Description

Sealant cartridge {Cartridge for sealant}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealant cartridge, and more particularly, to a sealant cartridge in which two-pack sealants and hardeners can be stored in different containers.

Sealants such as silicone sealant, polyurethane sealant or polysulfide sealant, UV sealant, UV adhesive, or UV coating agent are widely used for waterproofing window frames and joints.

Sealants are used in combination with a curing agent in the host material to speed up the curing process when exposed to air during use. These sealants are roughly divided into one part and two parts.

In the above, the one-pack sealant is packaged in a state in which a small amount of the curing agent is mixed in the main body in the same space. Such a one-part sealant has a merit that it is not only convenient to use but also does not generate bubbles during mixing because it does not mix by adding a curing agent to the main material at the time of use. However, since the one-part sealant is mixed with a small amount of hardener in the main material, it is cured slowly in the cartridge during storage, so the storage period is short, and since a small amount of hardener is mixed in the main material, There is a disadvantage in that the curing time is long after the discharge is completed by the operation.

In addition, the two-component sealant is discharged by the ejection gun in a state in which the main material and the hardener are respectively packed in different spaces, and the main material and the hardener are mixed and filled in the cartridge. The two-component sealant has a relatively long storage period compared to the one-component sealant because the curing agent is added to the base material and mixed before use. However, since the two-component sealant has to be mixed by adding a hardening agent to the main material when used, it is disadvantageous in use and disadvantages in that bubbles are generated due to mixing and the adhesive strength is lowered.

Accordingly, a cartridge has been developed that improves and has advantages of the one-component sealant and the two-component sealant. These cartridges form one body and are packaged in different spaces with a two-component sealant consisting of a main body only and a hardener.

The sealant cartridge 10 according to the prior art includes first and second main bodies 11 and 13, a nozzle portion 15, and first and second plungers 17 and 19.

The first and second bodies 11 and 13 have a cylindrical shape, the other side of which is open, and the outer surface is coupled to form a body. In the above, the first and second main bodies 11 and 13 are formed in a cylindrical shape in which the other side is opened as the main material and the curing agent are embedded in a liquid or paste state, respectively.

In the above, the main material embedded in the first main body 11 is discharged to bond the adherend, and the curing agent embedded in the second main body 13 is mixed with the main material embedded in the first main body 11 while being discharged and mixed to cure the main material. Speed up to cure faster.

In addition, the diameter of the first main body 11 and the second main body 13 is formed in proportion to the mixing ratio of the main material and the curing agent, wherein the main material has a larger mixing ratio than the curing agent, When the hardener is embedded in the second main body 13, the first main body 11 has a larger diameter than the second main body 13.

The nozzle unit 15 is installed at one end of the first and second main bodies 11 and 13, and each discharge port is formed by cutting with a knife or the like during use.

The first and second plungers 17 and 19 are installed to flow inside the other open sides of the first and second main bodies 11 and 13. In the above, the first and second plungers 17 and 19 have at least a portion of the outer surface contacting the inner surfaces of the first and second main bodies 11 and 13 so that the first and second plungers 17 and 19 are contacted by the user from the outside. It moves in one direction from the inside of the second body (11) (13) so that the built-in base material and hardener are discharged to the outside through each discharge port formed at one end of each nozzle unit (15).

In the above description, the first and second bodies 11 and 13, the nozzle unit 15, and the first and second plungers 17 and 19 are vinyl resin, polyethylene, polypropylene, polystyrene, and phenol resin. , Polyester, polyurethane, polyamide, polyvinyl chloride, fluororesin, ABS (Acrylonitrile Butadiene Styrene), it may be formed of any one of synthetic resins such as phenol resin and melamine resin. And the 1st and 2nd main body 11 and 13 containing the nozzle part 15 can be formed by injection molding.

In the above, a sealing coating (not shown) may be formed on each of the inner surfaces of the first and second bodies 11 and 13. In the above, each of the sealing coatings is introduced into the first and second bodies 11 and 13 from the outside through between the first and second bodies 11 and 13 and the first and second plungers 17 and 19. To prevent air from penetrating; Thus, the main body and the curing agent embedded in each of the first and second main bodies 11 and 13 are prevented from reacting with the air to solidify. In addition, each sealing coating acts as a lubrication to facilitate movement of the first and second plungers 17 and 19 in the first and second bodies 11 and 13.

The main body and the hardener built into the first and second main bodies 11 and 13 of the cartridge 10 for silicon according to the prior art described above, respectively, as shown in FIG. It discharges using the discharge gun 21 containing 25. The cartridge 10 cuts one end of the nozzle unit 15 before or after it is mounted on the discharge gun 21 to form respective discharge ports, and the mixer 27 is formed in the nozzle unit 15 where the respective discharge ports are formed. To combine.

When the cartridge 10 is mounted on the discharge gun 21 and the mixer 27 is coupled, the holding handle 29 of the discharge gun 21 is gripped and the operation knob 31 is operated to operate the first push rod ( 23 is moved from one side to the other to move the first plunger 17 into the first body 11 to discharge the embedded main body to the outside. The discharge gun 21 is directly applied to the first push rod 23 by the operation of the operation knob 31, and indirectly applied to the second push rod 25 through the first push rod 23. Accordingly, the second push rod 25 is also moved in one direction along with the first push rod 23 to move the second plunger 19 into the second main body 13 to discharge the built-in curing agent to the outside.

In the above, the main body and the hardener discharged from the first and second main bodies 11 and 13 to the outside are uniformly mixed by the mixer 27 to adhere the adhesive agent (not shown). In the above, the curing agent is mixed in the main material to which the adhesive is adhered, so that the hardening agent improves the curing speed of the main material so as to cure rapidly.

However, since the sealant cartridge according to the prior art is formed by combining the first and second bodies, the structure is complicated, making it difficult to manufacture and increasing the cost of the mold used during manufacturing. In addition, since the curing agent is higher in viscosity than the main material, it is discharged by the second pressing bar that indirectly applies the force rather than the first pressing force that directly applies the force. There was a problem that should be discarded without using. In addition, when the main material and the hardener built in the liquid or paste state in the first and second bodies, respectively, are stored for a long time, there is a problem of curing by infiltration of external air.

Accordingly, it is an object of the present invention to provide a sealant cartridge which can form a first body and a second body, respectively, and thus can have a simple structure and easy manufacturing while reducing the cost of a mold used in manufacturing.

In addition, since the first and second main bodies 41 and 43 including the first and second nozzle parts 45 and 47 are separated from each other, the structure is simple and can be easily manufactured by injection molding, respectively. The mold used for the test is also simple, which can prevent the cost increase.

The first sealing coating 53 is formed on the inner surface of the first body 41, and the second and third sealing coatings 55 and 57 are formed on the inner and outer surfaces of the second body 43, respectively. . In the above, the first, second and third sealing coatings 53, 55, 57 do not react with the main body and the curing agent embedded in the first and second bodies 41 and 43, respectively, and do not react with each other. Have In addition, the first, second and third sealing coatings 53, 55 and 57 have a viscosity of about 5 to 100 times higher than that of the main body and the curing agent incorporated in the first and second main bodies 41 and 43, respectively. It is formed by coating a silicone rubber or silicone compound in a paste state which has a lubricating function.

Therefore, the first sealing coating 53 is between the inner side of the first body 41 and the outer peripheral side of the first plunger 49, and the second sealing coating 55 is made of the inner side of the second body 43 and the first side. The outer circumferential side of the second plunger 51 and the third sealing coating 57 have external air between the outer side of the second body 43 and the inner circumferential side of the first plunger 49. 41) (43) to prevent the internal material and hardener from curing, respectively. In addition, the first, second and third sealing coatings 53, 55 and 57 are lubricated, so that the first and second plungers (in and out of the first and second main bodies 41 and 43) are lubricated. The movement of the 49 and 51 is facilitated.

In another embodiment of the present invention, the first, second, and third sealing coatings 53, 55, 57 are not formed, and the inner and outer circumferential sides of the first plunger 49 and the outer circumference of the second plunger 51 are provided. A sealant, such as a silicone rubber or silicone compound in a paste state, may be applied to the side surface. The sealing agent such as silicone rubber or silicone compound in a paste state applied to the inner and outer circumferential sides of the first plunger 49 and the outer circumferential side of the second plunger 51 may be formed of the first and the first agents.
