JPH10237918A - Dirt-proof water drain trap - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make it possible to maintain dirt-proof effect over a long period of time and also to realize deodorization effect by forming a thermoplastic resin composition blended with a particular amount of tourmaline powder to the thermoplastic resin and by constituting a dirt-proof water drain trap. SOLUTION: A thermoplastic resin composition is formed by blending 0.1 to 15wt.% tourmaline powder to a thermoplastic resin and a dirt-proof water drain trap is constituted. This tourmaline is a crystal electrically polarized without externally adding electricity, and the center of plus electric charge and the center of minus electric charge are deviated from the original positions. This deviation creates polarity and a surface activity is given to water contacting to the tourmaline. And the effect of resistance to bacteria and sterilization accelerates the surface activity of water of this water and the hydrolysis of chlorine dissolved in water, converts chlorine into HOCL- or COI- and these create the effect of bacteria resistance and others.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antifouling drainage trap, and more particularly to an antifouling drainage trap installed at an inlet of a drain pipe in a kitchen or a bathroom.

[0002]

2. Description of the Related Art Drainage from sinks installed in kitchens, kitchens, centralized kitchens and the like is discharged to a sewer through a drain pipe. Usually, a drainage port of the sink is provided with a perforated plate and a garbage storage basket so that cooking waste and garbage are not washed away, and a drainage trap provided with a water seal valve so that odor does not flow backward through the drainage pipe. Almost the same drain trap is provided at the drain port of the bathroom and the laundry drain port.

Referring to FIG. 1, an example of a drain trap of a sink will be described. A drain trap body 1 is attached to the bottom of the sink, and a drain port lid 2 is provided at the top of the drain trap body 1.
However, a rotating plate 3 is provided below, a garbage storage basket 4 is provided below, and a deodorant cap 5 is further provided below. The drain trap body 1 has a drain pipe (not shown) at its lowermost part. Zu) is connected. The drain trap is made of plastic or metal, and a part of the rotating plate 3 is made of rubber.

[0004] This drain trap is always moist, has nutrients such as cooking debris and food leftovers, and has an appropriate temperature, making it an environment extremely suitable for propagation of bacteria, bacteria, mold, and the like. I have. Therefore, in the summer, in a few days, even in the winter, about 1 to 2 weeks, slime due to the propagation of bacteria etc. occurs and it is not only dirty, but if left for a long time, the mesh of the garbage storage basket 4 is clogged and the water flows Gets worse. Therefore, it was necessary to frequently clean with a scourer or the like, or to clean with a chlorine bleach or a pipe cleaner.

[0005] The revolving plate 3 and the garbage storage basket 4 are still easy to clean, but the deodorizing cap 5 and the inside of the drain trap body 1 are difficult to clean, and the drains and washing drains in the bathroom are rarely cleaned. , Causing odor.
As a conventional technique for preventing such contamination by bacteria and the like, there is known a method in which an antibacterial agent, a bactericide, or the like is blended into plastic, which is a raw material of a drain trap. However, although this method is temporarily effective, the effect is weakened by hot water or kitchen detergent, and there is a problem that the antifouling effect is not maintained for a long period of time. In addition, since the sink is a place where food is handled and is often in contact with the human body, usable drugs are limited in terms of safety.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a drain trap having a long-lasting antifouling effect and an excellent odor preventing effect.

That is, the present invention relates to an antifouling drainage trap formed by molding a thermoplastic resin composition in which 0.1 to 15% by weight of tourmaline powder is blended with a thermoplastic resin.
This is an antifouling drain trap using a rubber composition in which 0.1 to 15% by weight of tourmaline powder is mixed with rubber.

Hereinafter, the present invention will be described in detail. As the thermoplastic resin as the main material of the thermoplastic resin composition of the present invention, any thermoplastic resin that can be injection-molded can be used. Examples of such a thermoplastic resin include high-density polyethylene (HDPE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile-styrene-butadiene resin (ABS),
Examples include polyamide (nylon), polyethylene terephthalate (PET), and polycarbonate (PC). And, from the viewpoint of durability against wastewater containing animal and vegetable oils and fats, detergent, heat resistance against high-temperature hot water and economic efficiency,
Polypropylene having a heat distortion temperature (HDT) of 100 ° C. or higher is preferred. Further, in order to improve heat resistance, glass fiber or the like may be blended.

Further, as the rubber which is the main material of the rubber composition of the present invention, any rubber which is usually used for packing a drain trap or the like can be used. Examples of such rubber include natural rubber and polybutadiene rubber (PB).
R), synthetic rubbers such as styrene-butadiene rubber (SBR) and chloroprene rubber (CPR). Chloroprene rubber is preferred from the viewpoint of durability.

In the present invention, a thermoplastic resin composition in which tourmaline is blended with a thermoplastic resin is used as a raw material for molding. Originally, Tourmaline
Is famous as a jewel, but the Curie brothers have tourmaline's electrical properties, ie, piezoelectric (piezoelectric) properties, in which a charge is generated on the crystal surface when pressure is applied, and pyroelectricity, which generates a charge in the same way when heating a crystal ( It is also called tourmaline for its discovery of pyroelectric properties. Tourmaline is basically a silicate mineral containing boron, belongs to a hexagonal system, shows an asymmetric image of asymmetrical top and bottom, and has a Mohs hardness of 7-7.
5, the specific gravity is 2.9 to 3.1, and the chemical formula of the representative one is as shown in the following formula (1). NaX ₃ Al ₆ B ₃ Si ₆ (O, OH) ₃₀ (OH, F) (1) (where X represents Mg, Fe, Mn, Li or Al)

In the above formula (1), tourmaline in which X is Mg is composed of magnesite tourmaline / Dravit (Dravit).
Called e), the color is brown, dark green or black, occurring in denatured rocks and pegmatite. X is Fe, Mn
Is referred to as black tourmaline, iron tourmaline, and shari, and is produced in pegmatite, which is black in color, and has the largest production of tourmaline. Tourmaline where X is Li and Al is red tourmaline, lithia tourmaline, and elbaite.
The color is produced in transparent red, green or bicolor, flaky Lithium mica. The electrical properties of tourmaline are due to the fact that plus and minus poles are always formed at both ends of the tourmaline crystal (Kubo et al., Solid Physics Vol. 24, No. 12, p. 1055, 1989)
Year). The safety of tourmaline has also been confirmed by dissolution tests of various substances and others.

The tourmaline used in the thermoplastic resin composition of the present invention is not particularly limited as long as it is tourmaline, but red tourmaline which does not hinder toning is preferable. The tourmaline to be mixed with the thermoplastic resin needs to be in a powder state, has an average particle size of 1 to 50 μm, and preferably passes through a 40 mesh sieve.

The compounding ratio of tourmaline in the thermoplastic resin composition is 0.1 to 15% by weight, preferably 0.5 to 15% by weight.
It is about 5% by weight. If the blending ratio of tourmaline is less than 0.1% by weight, the generation of slime and the like cannot be suppressed. Not only is the product damaged, but also the product strength and productivity are reduced.

In order to increase the productivity of the thermoplastic resin composition, a masterbatch was prepared in which the proportion of tourmaline in the resin composition was increased to 50 to 100% by weight. It is preferable that the batch and the thermoplastic resin are mixed so that the mixing ratio is attained.

In order to enhance the electric properties of tourmaline, a conductive material such as carbon black, graphite powder, stainless steel fiber, ZnO whisker, or the like may be used in combination with the resin composition. Further, a fiber reinforced plastic product may be prepared by blending inorganic fibers such as glass fiber, rock wool and ceramic fiber, and organic fibers such as vinylon and polyester fiber. Further, if necessary, various additives such as phenol-based, phosphorus-based, hindered phenol-based antioxidants and stabilizers, for example, lubricants such as metal soaps, and fluidity modifiers, as long as the object of the invention is not impaired. A filler or an antioxidant may be blended.

The method for preparing the resin composition is not particularly limited, and any method can be used. For example, it may be processed into pellets by a method of kneading and extruding a thermoplastic resin or tourmaline using various extruders, or a method of melt-kneading using a usual kneading machine such as a kneader or a Banbury mixer.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The method for forming the drain trap of the present invention is not particularly limited, and may be formed by a usual injection molding method or the like. The shape and size of the product can be arbitrarily determined according to the purpose of use of the drain trap, and there is no particular limitation. For example, for a kitchen sink, as shown in FIG. 1, the drain trap body 1, the drain port lid 2, the revolving plate 3, the garbage storage basket 4, and the deodorant cap 5 are molded articles of a thermoplastic resin composition. be able to. The drainage receiving part, the eye plate and the deodorizing cap can be made of a thermoplastic resin composition for a bathroom, and the drainage receiving part and the deodorizing cap can be made of a thermoplastic resin composition for a washing drain.

In the case where the rubber packing is attached to the drain lid 2 and the rotating plate 3 and the rotating plate 3 is made of rubber, a rubber composition in which tourmaline is mixed with rubber is used. Is preferred. In this case, the type, the mixing ratio, and the like of tourmaline may be the same as the resin composition of the thermoplastic resin and tourmaline.

[0019]

The thermoplastic resin composition or the rubber composition used in the antifouling drainage trap of the present invention is obtained by blending tourmaline with a thermoplastic resin or rubber. This tourmaline can be prepared without externally applying electricity. The center of the positive charge and the center of the negative charge are displaced from the position where they should be located in the crystal having the electric polarization. This shift causes polarity and imparts surface activity to the water that comes into contact with the tourmaline powder. The effects of antibacterial and sterilization are the surface activity of this water and the hydrolysis of dissolved chlorine dissolved in water. that accelerate the chlorine HOCl and OCl ^- changed to such as these are considered to have an effect, such as antibacterial.
