Problems solved by technology

[0004] 1. Silica sol is gelled alone, mainly in the state of small particles, and can be formed by adding various pigments, fillers or additives, but the film is very brittle and easy to crack
[0005] 2. Easy to mold, poor gloss
[0006] 3. Silica sol has poor stability and is easily affected by pH, ions, temperature, additives, fillers, etc.
[0007] 4. The mixing performance of silica sol and emulsion is poor, and the compatibility is not good, so modifiers need to be added
[0008] 5. Silica sol and emulsion are mixed with various additives, fillers, etc., the system stability is very poor, it is easy to gel, scrapped, the technical requirements are extremely strict and there are usually no rules
[0009] 6. After mixing silica sol and emulsion, the stability of the finished paint is poor, and the final thickening is serious

Abstract

The invention provides a high-modulus lithium silicate / potassium trimethylsilanolate adhesive agent and an inorganic interior wall environment-friendly coating prepared through the adhesive agent. The adhesive agent is obtained through a one-step reaction conducted on a silica solution, potassium trimethylsilanolate and lithium hydroxide monohydrate. The environment-friendly coating is composed of water, the adhesive agent of the inorganic interior wall environment-friendly coating, rutile titanium dioxide, calcium stearate, calcined kaolin, calcium carbonate, methylcellulose and auxiliaries. The coating has the advantages of being free of TVOC, free of smell, environmentally friendly and the like, is high in stain resistance, resistant to water scrubbing and dense in paint film, has the graffiti function of waterproof pens and more accords with the requirement of child health paint.

Description

technical field [0001] The invention relates to an inorganic interior wall environmental protection paint and a production process thereof. Background technique [0002] As people have higher and higher requirements for indoor air quality. As well as the increasing shortage of petroleum resources, pure inorganic environmental protection coatings will surely become the direction of future development. [0003] At present, inorganic coatings usually adopt the method of modifying acrylic emulsion with silica sol. This coating cannot be strictly called an inorganic coating. The combination of silica sol and acrylic emulsion has the following disadvantages: [0004] 1. Silica sol is gelled alone, mainly in the state of small particles, and can be formed by adding various pigments, fillers or additives, but the film is very brittle and easily cracked. [0005] 2. Easy to mold and poor luster. [0006] 3. Silica sol itself has poor stability and is easily affected by pH, ions, t...
