Abstract

The invention discloses a nano-material modified thermal insulation interior wall coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 30-50 parts of acrylic emulsion, 2-4 parts of titanium dioxide, 3-5 parts of an enhancement solution, 0.3-0.5 part of a defoaming agent, 0.5-2 parts of a dispersing agent, 1-3 parts of a film-forming agent and 20-30 parts of water. The enhancement solution is prepared in the preparation process, the enhancement solution can also have a large amount of long-chain alkyl, the long-chain alkyl has a good hydrophobic effect, after the coating forms a coating film, the surface of the coating film has a good hydrophobic effect, meanwhile, the coating film is more convenient to clean, meanwhile, the coating film contains macromolecular chains and has good corrosion resistance, the internal rotation barrier energy of the molecular chain is low, and the molecular chain segment is easy to rotate, so that the toughness of the dried coating film is higher, the coating film is not easy to scratch, and the attractiveness of the coating film is ensured.

Description

technical field [0001] The invention relates to the technical field of coating preparation, in particular to a nano-material modified thermal insulation interior wall coating and a preparation method thereof. Background technique [0002] 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. There are many kinds of coatings, and their performance characteristics are different from each other. Various coatings and modified coatings have appeared on the market. Interior wall coatings are latex paints for general decoration. Latex paint is an emulsion material. According to different substrates, it can be divided into two categories: polyvinyl acetate emulsion and acrylic emulsion. Latex paint uses water ...
