Abstract

The invention discloses an environment-friendly inner wall coating material and a preparation process thereof. The environment-friendly inner wall coating material is prepared from, by weight, 60-80 parts of diatomite, 70-90 parts of quartz sand, 15-30 parts of sepiolite, 20-30 parts of nano calcium silicate, 8-20 parts of calcium hydroxide powder, 5-10 parts of bamboo charcoal fibers, 1-5 parts of glass fibers, 0.6-2 parts of potassium perborate, 1-3 parts of nano zinc oxide, 0.2-0.6 part of kathon, 0.1-0.5 part of a dispersing agent, 0.2-0.8 part of a wetting agent and 0.1-0.3 part of an antifoaming agent. The preparation process of the inner wall coating material includes diatomite purification and mixed ball milling. The environment-friendly inner wall coating material has advantages of safety, environmental friendliness and excellent antibacterial, waterproof, mould-proof and fireproof performances and is suitable for serving as coating for inner walls, and the preparation process is simple.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly interior wall coating material and a preparation process thereof. Background technique [0002] With the development of society and the improvement of living standards, people's awareness of environmental protection and health has been significantly enhanced, and the requirements for the comfort and safety of the living environment are getting higher and higher. Indoor temperature, air relative humidity, and air quality are important environmental parameters for living comfort. Diatom mud is a kind of interior wall coating material based on diatom earth. Diatom earth is a single-celled aquatic plankton that lived millions of years ago. After diatoms die, they will deposit on the bottom of the water. Hundreds of millions of years of accumulation and geological changes become diatomaceous earth. The main component of diatomite is protein, which ...
