Sound-insulation shock-absorption antibacterial coating and preparation method thereof

Abstract

The invention discloses a sound-insulation shock-absorption antibacterial coating and a preparation method thereof. The formula comprises the following raw materials in parts by weight: 150-200 partsof cement, 100-150 parts of heavy calcium carbonate powder, 130-180 parts of wood fiber, 50-80 parts of sepiolite fiber, 30-60 parts of basalt fibers, 20-40 parts of micronized glass beads, 3-5 partsof hydroxypropyl methyl cellulose, 8-15 parts of redispersible latex powder, 10-20 parts of shells, 10-20 parts of medical stone, 5-10 parts of nano titanium dioxide, 1-3 parts of Octakis(trimethylsiloxy)silsesquioxane, 3-5 parts of a dispersing agent and 2-4 parts of toner. The coating provided by the invention not only has the advantages of good shock absorption, sound insulation, antibiosis, flame retardance, adhesive property, dispersibility, lower cost and the like, but also is excellent in environmental protection performance and harmless to human bodies, can purify the air and remove harmful substances such as formaldehyde in the air, and can be widely applied to the building fields such as residences, schools, hospitals, hotels and office buildings.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a sound-insulating, shock-absorbing and antibacterial coating and a preparation method thereof. Background technique [0002] The noise pollution that occurs in the society now is particularly prominent because of its indoor noise pollution, which brings great inconvenience to people's normal life. Therefore, everyone attaches great importance to indoor noise pollution, but the construction technology of sound insulation products on the market is complicated, the price is high, and the sound insulation effect is not obvious. Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. [0003] Existing coatings o...

AI Technical Summary

Problems solved by technology

[0003] Existing coatings often have some technical defects, such as poor adhesion, easy to fall off, poor noise prevention, shock absorption, and antibacterial effects, prone to mildew or oxidation, poor water resistance, and easy to occur due to humid air. Moldy phenomenon, especially during the rainy season in the south, the air is more humid, and it is more likely to have mildew on the inner wall, which brings a lot of inconvenience to consumers

Secondly, most of the existing paint products have poor dispersion, and the paint liquid has agglomeration and agglomeration during the spraying process, resulting in uneven brushing; again, most of the existing paint products contain certain formaldehyde, Harmful substances such as volatile organic compounds usually require long-term ventilation before they can be used normally, and some harmful substances such as formaldehyde in some coatings are also easy to volatilize, and the environmental protection performance is very poor. lasting harm to the body
