A kind of weak alkaline inorganic multifunctional diatom mud dry powder coating and preparation method thereof

Abstract

The invention relates to a weakly alkaline inorganic multifunctional diatom ooze dry powder paint. The invention is characterized in that the paint is composed of the following components in parts by weight: 10-15 parts of diatom ooze, 5-30 parts of titanium white, 8-10 parts of 2000-mesh nano calcium carbonate, 25-40 parts of 600-mesh calcium carbonate, 3-5 parts of kaolin, 5-15 parts of talcum powder, 5-10 parts of zeolite powder, 1-2 parts of nano titanium dioxide, 1-2 parts of zinc oxide, 2-4 parts of tourmaline powder, 2 parts of powder defoaming agent, 2 parts of powder dispersing and wetting agent, 10 parts of dispersible latex powder, 2-4 parts of inorganic bentonite, 1-2 parts of cellulose ether, 2-4 parts of silicon dioxide, 5-8 parts of potassium methane-silicate powder, 5-8 parts of sodium methane-silicate powder, 0.3-0.5 part of silane coupling agent and 0-3 parts of inorganic pigment. The paint has the advantages of long storage time, stable performance, bright color, easy color matching, favorable weather resistance, high covering rate, stable color and delicate hand feeling.

Description

technical field

[0001] The invention relates to the field of fine chemicals, in particular to a weakly alkaline inorganic multifunctional diatom mud dry powder coating and a preparation method thereof. Background technique

[0002] Architectural coatings are mainly water-based coatings, which use water as the dispersion medium, including water, emulsion, fillers, additives, etc. However, as high as 40-55% of water in the composition of water-based paints and high packaging costs, it takes a lot of manpower, material and financial resources for the packaging and transportation of water-based paints; at the same time, a large amount of organic anti-mold preservatives are needed to ensure product shelf life. and storage. Therefore, the development of dry powder coatings is the current market demand. At present, inorganic dry powder coatings on the market are generally added with inorganic film-forming components such as cement, lime or gypsum, which have the advantages of anti...
