Abstract

The invention relates to a coating paint for plywood and a preparation method of the coating paint. The coating paint is prepared from the following raw materials in parts by mass: 50-60 parts of epoxy modified acrylic resin, 18-24 parts of hexamethoxy methyl melamine resin, 7-12 parts of butyl acrylate, 3-6 parts of dibutyl phthalate, 0.015-0.028 part of 2-amino-2-methyl-1-propyl alcohol, 3-6 parts of polyacrylate resin, 0.15-0.25 part of cellulose acetate butyrate, 0.15-0.25 part of polysiloxane, 8-15 parts of alcohol-soluble fast yellow GR, 4-10 parts of dimethyl ether, 0.5-2 parts of water-proofing agent, 7-15 parts of isopropyl alcohol, 3-6 parts of isopropyl acetate, and 7-12 parts of distilled water. The paint provided by the invention has good appearance, processability and weatherability, and is not easy to be abraded after the plywood is coated with the paint, and the plywood can be kept attractive and durable for a long period of time.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coating finish paint for splints and a preparation method thereof. Background technique [0002] Plywood, also known as plywood, is made of three or more layers of 1mm-thick veneer or sheet glued by hot pressing. It is the most commonly used material for hand-made furniture, such as furniture manufacturing, interior decoration, and residential construction. sheet. Plywood not only has all the advantages of natural wood, such as light bulk density, high strength, beautiful texture, insulation, etc., but also can make up for some natural defects of natural wood, such as knots, small format, deformation, and large differences in vertical and horizontal mechanics. The splint also has the advantages of good elasticity and toughness, impact and vibration resistance, easy processing and painting. [0003] In daily use, in order to improve the aesthetics and use value of the plywood, it is ne...
