Sound insulation coating for door and preparation method thereof

Abstract

The invention discloses a sound insulation coating for a door. The sound insulation coating is prepared from the following materials in parts by weight: 30-35 parts of nano calcium carbonate, 8-10 parts of isocyanate, 12-14 parts of silicon powder, 15-20 parts of toluene diisocynate, 4-8 parts of methyl cellulose, 6-14 parts of fluororesin, 3-7 parts of polyphenylene sulfide, 14-18 parts of polysulfone, 35-40 parts of activated aluminium oxide, 16-20 parts of resol, 6-10 parts of polyisocyanate, 22-26 parts of tetrabutyl phosphoric chloride, 15-20 parts of triethanolamine, 4-9 parts of silicon carbide, 15-20 parts of kaolin, 4-8 parts of graphite, 11-16 parts of polyvinyl alcohol, 33-36 parts of hydrogenated castor oil, 40-45 parts of polyamide wax, 22-24 parts of titanium dioxide, 8-9 parts of zinc chromate, 20-26 parts of sodium lauryl sulfate, and 30-35 parts of trichlorofluoromethane. The sound insulation coating for the door is good in sound insulation effect, has water absorption and dampproof functions, and is steady in chemical performance.

Description

technical field [0001] The invention relates to a sound-insulating coating for a door and a preparation method thereof. Background technique [0002] Paint, traditionally called paint in China. The so-called 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, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a paint film or a coating." [0003] The main sound-insulating raw m...

Problems solved by technology

[0004] At present, the existing door sound insulation coating does not have a good sound insulation effect, and does not have the function of water absorption and moisture resistance, and its chemical properties are unstable.
