Embodiment 1

[0021] The coating composition with air purification function of this example is as follows:

[0022] Modified bentonite formaldehyde adsorbent 40%, modified bentonite 8%, modified sepiolite 15%, kaolin 13%, nano silver-loaded antibacterial agent 0.5%, titanium dioxide 6.5%, calcium carbonate 9.7%, diatomite tailings 4%, methyl cellulose 2.7%, wood fiber 0.6%.

[0023] The modified bentonite formaldehyde adsorbent is obtained by heating bentonite in sulfuric acid or hydrochloric acid, and then irradiating with microwaves. The specific preparation method is operated according to Chinese patent application 201610244147.4.

[0024] Modified bentonite is obtained by mixing bentonite with sodium carbonate or sodium fluoride at a mass ratio of 24:1 for 7 days, then drying at 80-100°C, and crushing to 320 mesh. The specific preparation method is as follows: crush the bentonite raw ore, select bentonite with a montmorillonite content of ≥80% (mass ratio), the mass percentage is 96%,...

Embodiment 2

[0031] The coating composition with air purification function of this example is as follows:

[0032] Modified bentonite formaldehyde adsorbent 30%, modified bentonite 10%, modified sepiolite 20%, kaolin 20%, nano silver-loaded antibacterial agent 0.2%, titanium dioxide 7.5%, calcium carbonate 5%, diatomite tailings 2%, methyl cellulose 5%, wood fiber 0.3%.

[0033] All the other are the same as embodiment one.

Embodiment 3

[0035] The coating composition with air purification function of this example is as follows:

[0036] Modified bentonite formaldehyde adsorbent 50%, modified bentonite 5%, modified sepiolite 10%, kaolin 10%, nano silver-loaded antibacterial agent 1%, titanium dioxide 4%, calcium carbonate 15%, diatomite tailings 3%, methylcellulose 1%, wood fiber 1%.

[0037] All the other are the same as embodiment one.

Abstract

The invention belongs to the field of environmental protection, and discloses a coating with the air purifying function. The coating is prepared from 30%-50% of a modified bentonite formaldehyde adsorbing agent, 5%-10% of modified bentonite, 10%-20% of modified sepiolite, 10%-20% of kaolin, 0.2%-1% of a nanometer silver-carrying antibacterial agent, 4%-8% of titanium dioxide, 5%-15% of calcium carbonate, 2%-6% of kieselguhr tailings, 1%-5% of methylcellulose and 0.3%-1% of wood fiber. A preparing method includes the steps that the raw materials are put into a stirring machine and jointly mixed and stirred to be even, and the powdery coating with the air purifying function is obtained. According to the coating with the air purifying function, an existing air purifying material is low in purifying efficiency, and has the harmful defects, and the coating with the air purifying function is free of rubber powder and cement, high in purifying efficiency, nontoxic and free of pollution.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a paint with air purification function. Background technique [0002] International environmental protection experts have listed "indoor air pollution" as the third generation of air pollution after "soot type" and "photochemical smog type" pollution. People have carried out a lot of researches on air purification, and have developed various materials with the function of purifying air. For example, Chinese patent CN102584113B uses diatomite, attapulgite powder, rubber powder and other raw materials to prepare environmentally friendly interior wall coatings, but the invention The diatomite and attapulgite powder have not undergone necessary modification treatment. The rubber powder itself contains organic volatiles such as formaldehyde, and the microporous characteristics of the diatom mud will be sealed by the colloid and cannot be adsorbed. Function, resulti...
