Resin for carpentry paint and carpentry paint

Abstract

The invention provides resin for carpentry paint. The resin is prepared from the following components in parts by weight: 5-9 parts of n-butyl acrylate, 12-20 parts of methyl methacrylate, 7-12 parts of n-butyl methacrylate, 1-3 parts of styrene, 0.5-1 part of methacrylic acid, 1.5-4 parts of a cross-linking agent, 0.5-1 part of an initiator, 0.5-1 part of a fluorinated surfactant, 1.5-4.5 parts of an emulsifying agent and 1-2 parts of ammonia water. The resin for the carpentry paint is low in film-formation temperature, and can realize self-crosslinking at room temperature and low temperature; an obtained paint film is high in hardness, strong in adhesion and good in toughness; the paint film is maintained not to crack when the volume of wood is changed. Experimental results prove that the hardness of the carpentry paint can reach 2H in the fourth day after the carpentry paint is sprayed. The invention also provides the carpentry paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a resin for wood varnish and wood varnish. Background technique [0002] With the development of the economy and the improvement of people's living standards, the requirements for interior decoration are getting higher and higher. Wood lacquer is a kind of wood coating for interior decoration, which is mainly used for coating on the surface of wood to improve the smoothness of the surface of wood and make it more beautiful. At present, wood paint mainly melts the paint through organic solvents, and then coats it on the surface of the wood. After the organic solvent volatilizes, the paint can be cured on the wood. Since most paints use organic solvents, they not only pollute the environment, but also harm the human body. harmful. Therefore, the use of this kind of wood paint is restricted all over the world, and the product that replaces this kind of wood paint is water-based w...
