Problems solved by technology

In order to meet people's needs, there are several wall materials on the market that absorb and purify harmful substances in the air. In order to protect their air permeability, only a small amount of environmentally friendly latex powder or cement and other materials are added, but they have the following disadvantages: the bonding is not firm It is easy to lose powder, the wall absorbs water and is easily stained, it is not resistant to washing and is difficult to clean after being soiled, and the air is humid for a long time and absorbs too much water to cause bacteria to multiply and mold

Abstract

The invention discloses a composite antibacterial diatom mud coating which comprises the following raw materials in part by weight: 10-20 parts of porous basalt, 20-35 parts of diatomite, 8-13 parts of sodium silicate, 9-14 parts of medical stone, 12-17 parts of bentonite, 6-11 parts of wollastonite, 7-13 parts of kaolin, 5-10 parts of sepiolite, 4-9 parts of dolomite, 3-6 parts of graphene oxide,7-11 parts of modified wheat straw fibers, 3-6 parts of calcium carbonate, 2-5 parts of nano titanium dioxide, 1-3 parts of cellulose ether, 2-4 parts of negative ion powder and 1-3 parts of a dispersing agent. The composite antibacterial diatom mud coating disclosed by the invention is scientific and reasonable in formula, good in air permeability, resistant to wash and mildew-proof and has indoor odorous smoke dust removing and self-cleaning effects.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a composite antibacterial diatom mud coating and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's requirements for decoration are getting higher and higher. When people are pursuing high-end decoration effects, they are bound to put forward higher requirements for "wall materials". In order to meet people's needs, there are several wall materials on the market that absorb and purify harmful substances in the air. In order to protect their air permeability, only a small amount of environmentally friendly latex powder or cement and other materials are added, but they have the following disadvantages: the bonding is not firm It is easy to lose powder, the wall absorbs water and is easily stained, it is not resistant to washing and is not easy to clean up after being soiled, and the air is humid for a long ti...
