Ecological type multi-functional inorganic water-based dry powder coating capable of purifying air

Abstract

The invention discloses an ecological type multi-functional inorganic water-based dry powder coating capable of purifying air. The coating is prepared from, by mass, 50-65% of veined stone powder, 15-35% of superfine ash-calcium powder, 0.2-0.5% of powder thickener TF-05, 0.1-0.2% of dispersant SN-5040, 0.2-0.5% of a powder coalescing agent P871, 0.6-1.0% of hydroxyethyl cellulose and 0.2-0.8% of an AD anti-setting agent. The veined stone powder is natural mineral powder, a production process of the coating is simple, environmentally friendly and healthy, hydroxy anions generated by the coating purifies the air mainly through the processes such as electric property neutralization, a chemical reaction and physical adsorption, and through the adsorption electric property neutralization effect, part of dissociative fine-grain gas molecules floating in the air can be adsorbed by the hydroxy anions and then fall down to the ground due to self weight, so that the air can be purified.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to an ecological multifunctional inorganic water-based dry powder paint capable of purifying air. Background technique [0002] Coatings are one of the largest sources of indoor pollution. The current architectural coatings use synthetic resin as the main film-forming material, and some use organic solvents, especially in the process of manufacturing and construction of organic coatings. A certain amount of organic solvents are used. Solvents are directly discharged into the atmosphere during the production and construction of coatings, resulting in environmental and health damage, and the technological progress of conventional coatings mostly focuses on improving the weather resistance, suspension, pollution resistance, aging resistance of coatings, etc. On the other hand, although conventional coatings have strong wall decoration and protection functions, they do not hav...

Problems solved by technology

[0002] Coating is one of the biggest sources of indoor pollution. The current architectural coatings all use synthetic resin as the main film-forming substance, and some use organic solvents. Especially in the process of manufacturing and construction of organic coatings, a certain amount of organic solvents are used. These organic Solvents are directly discharged into the atmosphere during the production and construction of coatings, causing environmental and health damage, and most of the technological progress of conventional coatings focuses on improving the weather resistance, suspension, pollution resistance, and aging resistance of coatings. On the one hand, although conventional paints have strong wall decoration and protection functions, they do not have the functions of purifying the air, generating negative ions and inhibiting bacteria, and the commonly used materials for interior decoration contain more or less nitrides, chlorides, Sulfide, formaldehyde and other organic and inorganic harmful substances, these harmful substances emitted by the decoration materials containing harmful substances, will linger indoors for a long time, causing great harm to the human body. If the human body inhales these harmful gases too much, it will cause breathing Difficulty, dizziness, tears and vomiting, etc. Therefore, it is the greatest wish of every user who needs to carry out interior decoration to remove these residual harmful gases as soon as possible and purify the air.
