Abstract

The invention aims to provide a charcoal and mineral crystal compound air purifying material and a preparation method thereof. According to the technical scheme provided by the invention, by taking wood sawdust as a carrier, the charcoal and mineral crystal compound air purifying material is formed by carbonizing bentonite, diatomite, sepiolite and tourmaline in vacuum; and the preparation method disclosed by the invention comprises the following steps: (1), drying the wood sawdust at 50-70 DEG C for 8-12 h; (2), adding 1-10% of bentonite, 1-10% of diatomite, 1-10% of sepiolite and 1-10% of tourmaline powder, stirring at room temperature for 1-3 h after adding water, and standing for 5-10 h; (3), removing supernatant, drying at 50-70 DEG C, heating solid matters in vacuum to 200-500 DEG C, and activating; and (4), after activating for 2 h, cooling to room temperature and grinding, and sieving through a 100-mesh sieve, thus obtaining the compound air purifying material.

Description

Brilliant material for air purification of a kind of charcoal grandidierite and preparation method thereof

Technical field

The present invention relates to air purifying process field, be specifically related to brilliant material for air purification of a kind of charcoal grandidierite and preparation method thereof.

Background technology

Raising along with socio-economic development and living standards of the people, modern is for the living environment pay attention to day by day that is signifying quality of life, yet the especially chemically composited material of various new decorative material for building carries the toxic gases such as a large amount of formaldehyde, benzene homologues, ammonia, room air is caused to serious pollution, and the malaise symptoms such as sears optical, skin are itched, headache, failure of memory frequently occur.The research of material for air purification has become scientist's the focus of attention.

Absorption method is because its method is simple and the pollution-free absorption that is widely used in pernicious gas.But most adsorbents exist that adsorption efficiency is low, saturated velocity is fast, or cost is higher, and even some can bring the shortcomings such as secondary pollution, the research and development of therefore efficient cheap scavenging material easy to use are very urgent.

Summary of the invention

The object of this invention is to provide brilliant material for air purification of a kind of charcoal grandidierite and preparation method thereof, to overcome the existing defect of current adsorbent.For achieving the above object, the technical solution used in the present invention is as follows:

Using wood sawdust as carrier, through adding bentonite, diatomite, sepiolite and tourmaline vacuum carbonized to form.Preparation method comprises the steps:

1, wood sawdust is dried to 8-12h at 50-70 ℃;

2, the bentonite that adds 1-10%, the diatomite of 1-10%, 1-10% sepiolite, 1-10% tourmaline powder, adds water stirring at room 1-3h, standing 5-10h;

3, remove supernatant, 50-70 ℃ of oven dry, then activate being heated to 200-500 ℃ under solid matter vacuum condition;

4, after activation 2h, be cooled to room temperature and pulverize, cross 100 mesh sieves, obtain the brilliant material for air purification of this grandidierite.

The present invention is usingd wood sawdust as carrier, take other sorbing materials as auxiliary material, is mixed and processed.Wood sawdust, loose porous, after mixing with bentonite, diatomite, sepiolite and tourmaline powder, adding water stirs, sawdust is in water suction, bentonite, diatomite, sepiolite and tourmaline powder are drawn in body and surface, carry out again vacuum carbonized, formed the brilliant material for air purification of a kind of charcoal grandidierite.

The present invention has following distinguishing feature:

(1) invent described material for air purification, raw material sources are extensive, cheap;

(2) invent described material for air purification preparation method simple, adsorption rate is high;

(3) invent described material for air purification stable performance, the life-span is long, can preserve for a long time use.

the specific embodiment:

1,80g wood sawdust is dried to 10h at 50 ℃;

2, the bentonite that adds 7g, the diatomite of 6g, the sepiolite of 3g, the tourmaline powder of 4g, adds 500ml

Water stirring at room 3h, standing 10h;

3, remove supernatant, 50 ℃ of oven dry, then activate being heated to 300 ℃ under solid matter vacuum condition;

Embodiment 2:

1,80g wood sawdust is dried to 12h at 60 ℃;

2, the bentonite that adds 6g, the diatomite of 5g, the sepiolite of 6g, the tourmaline powder of 3g, adds 500ml

Water stirring at room 2h, standing 8h;

3, remove supernatant, 60 ℃ of oven dry, then activate being heated to 400 ℃ under solid matter vacuum condition;

Embodiment 3:

1,80g wood sawdust is dried to 8h at 70 ℃;

2, the bentonite that adds 7g, the diatomite of 4g, the sepiolite of 3g, the tourmaline powder of 6g, adds 500ml

Water stirring at room 1h, standing 5h;

3, remove supernatant, 70 ℃ of oven dry, then activate being heated to 500 ℃ under solid matter vacuum condition;
