Abstract

The invention relates to a fireproof and insect-proof interior wall coating. The coating is characterized by comprising the following components in parts by mass: 40-80 parts of water-based syntheticresin emulsion, 50-100 parts of silica sol, 100-200 parts of potassium silicate, 15-30 parts of a methylsiloxane derivative, 40-80 parts of an insect prevention mixed solution. In the water-based synthetic resin emulsion, water-based synthetic resin is a copolymer of ethylene and vinyl acetate; and the size of the silica sol is 10-20 nm. The coating has the following beneficial effects: the coating has good compatibility, does not contain APEO, does not contain VOC, and does not depend on raw materials of film-forming assistants, antifreezing agents and other assistants; and the characteristics of fire resistance, good paint film air permeability and high water vapor permeability of inorganic materials are utilized, and in combination with the effects of the anti-mosquito mixed liquid, theanti-mosquito mixed liquid can play a role for a long time.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a fire-proof and insect-proof interior wall coating and a preparation method thereof. Background technique [0002] The interior wall coating has the characteristics of convenient construction, outstanding performance, safety and environmental protection, and occupies a dominant position in domestic interior wall decoration, and its market share exceeds 70%. At present, with the improvement of people's living standards and concepts, the decorative demand is only one aspect considered by consumers. More consumers are beginning to pursue the functionality and environmental performance of interior wall coatings. Due to the use of organic film-forming substances, the paint does not have its fireproof performance, and some inorganic paint formulations have poor stability and are easy to crack. [0003] The climate in summer is humid and hot, which is more suitable for the breeding and activit...
