Problems solved by technology

[0004] When diatom mud is made into coatings, it often has insufficient toughness and cannot be painted on a large area. At the same time, because auxiliary materials are often added during production and processing to expand the volume and reduce costs, this also has a negative effect on the impact resistance of diatom mud coatings. influences

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-toughness, impact-resistant and sterilized diatom mud coating. Background technique [0002] Diatom mud has the functions of adjusting humidity, releasing negative oxygen ions, fire retardant, sterilization and deodorization, etc. It is an excellent indoor coating. China is the country with the largest content and export of diatom mud in the world. The composition of diatom mud is A regular and neatly arranged circular or needle-shaped micron-scale porous material, with a porosity of up to 90%, and thousands of times more micropores per unit area than charcoal, with extremely strong physical adsorption properties and ion exchange performance. [0003] Negative ion powder is a kind of composite mineral that is artificially synthesized or proportioned by human beings using the principle of negative ions produced in nature. The negative ions released by negative ion powder...
