Environmentally friendly diatom mud wall material and preparation method thereof

Abstract

The invention belongs to the field of indoor decoration coating, and relates to an environmentally friendly diatom mud wall material. The material is mainly prepared from, by weight, 50-75 parts of diatomite, 10-13 parts of nanometer titanium dioxide, 10-12 parts of ground calcium carbonate, 5-9 parts of wollastonite powder, 5-8 parts of quartz powder, 4-8 parts of attapulgite powder, 4-8 parts ofsierozem powder, 4-6 parts of graphene, 3-7 parts of propyl gallate, 2-7 parts of negative ion powder, 2-15 parts of a dispersant, 5-9 parts of a surface modifier, 5-10 parts of a mildew-proof antibacterial agent, 2-7 parts of a water resistant agent and 5-8 parts of a binder. The preparation process of the diatom mud wall material is simple, and the diatom mud wall material produced has better mildew-proof and antibacterial properties and excellent strength, flexibility and crack resistance, and overcomes technical problems including easy powder falling, easy cracking, low strength and no stain resistance of diatom mud wall materials.

Description

technical field

[0001] The invention belongs to the field of interior decoration coatings, and in particular relates to an environment-friendly diatom mud wall material and a preparation method thereof. Background technique

[0002] The main component of diatom mud is diatomaceous earth, and the main component of diatomaceous earth is diatoms. Diatoms are the first single-celled algal organisms that appeared on the earth. They live in seawater or lake water, and their shapes are extremely small. The main component of diatom mud is protein, which is rich in a variety of beneficial minerals and has a soft texture. Use an electron microscope to observe diatom mud. Diatom mineral is a micron-scale porous material. There are countless tiny holes on the surface of the particles, which are regularly and neatly arranged in circles and needles, with a porosity of more than 90. The number of micropores is thousands of times more than that of charcoal. This molecular sieve structure...
