Abstract

The invention discloses an anti-falling internal and external wall basaltic mud coating which solves the technical problems that an existing coating is not high in strength and prone to cracking and falling, and belongs to the technical field of coating preparation. The coating is prepared from, by weight, 20-30 parts of basalt powder, 8-12 parts of shell powder, 4-8 parts of kieselguhr, 2-5 partsof sodium carboxymethylcellulose, 1-5 parts of quartz stone powder, 0.1-0.3 part of graphene and 6-10 parts of activated carbon. The invention further provides a preparing method of the anti-fallinginternal and external wall basaltic mud coating. The method includes the steps of raw material mixing, stirring, drying and the like. The anti-falling internal and external wall basaltic mud coating has the advantages of being high in wall surface adhesiveness, high in durability, free of chalking, free of color fading and free of cracking and falling and is suitable for indoor decoration of various types of buildings. The preparing method is easy to implement and suitable for large-scale production.

Description

technical field [0001] The present invention relates to the technical field of paint preparation, in particular to a kind of anti-shedding basalt mud paint for interior and exterior walls and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, the problems of decoration pollution and indoor pollution have been widely concerned and valued, people's aesthetic level has gradually changed, and people's requirements for home decoration have also been further improved. There is a higher demand. [0003] At present, the market of coatings is numerous, and although variety is abundant, all have shown respective advantages and disadvantages to varying degrees. For example, although traditional water-soluble paints such as polyvinyl alcohol are cheap, they have poor durability and are not waterproof. Emulsion paints such as acrylic esters contain a variety of additives, which are not environmentall...
