Abstract

The invention relates to water soluble environment-friendly coating for an inner wall and a preparation method thereof. The coating comprises the following components in parts by weight: 0.8-3 parts of chitosan, 0.5-3 parts of polyvinylpyrrolidone, 20-30 parts of kaolin, 4-7 parts of titanium white, 1-5 parts of silicon dioxide, 55-65 parts of solvent, 1-3 parts of acetic acid and 1-3 parts of glycerol. Compared with the prior art, the water soluble environment-friendly coating provided by the invention has the advantages of all qualified indexes, favorable environment friendliness, proper price, and the like.

Description

technical field [0001] The invention relates to an interior wall paint, in particular to a water-soluble environment-friendly paint for an interior wall and a preparation method thereof. Background technique [0002] Coatings (especially interior wall coatings) have a history of several decades. Due to the basic use of organic solvents, they produce great toxicity during the storage, preparation, construction and use of raw materials, which damages people's health. At the same time It also pollutes the environment. As a result, water-soluble paints are produced in an effort to reduce the harm to people and the environment. However, due to the limitations of raw materials and imperfect preparation methods, water-soluble paints still have many deficiencies in construction and use by users. Therefore, in the preparation of water-based paints When coating, a wide variety of additives are added in order to achieve various properties, which greatly increases the probability of to...
