Macromolecular electrostatic powder capable of improving flame retardant property of plate

Abstract

The invention provides macromolecular electrostatic powder capable of improving the flame retardant property of a plate, belonging to the technical field of electrostatic spraying powder. The macromolecular electrostatic powder capable of improving the flame retardant property of the plate in the invention comprises the following raw materials in parts by weight: 40-50 parts of epoxy resin, 4-6 parts of a thermal curing agent, 2-4 parts of dicyclopentadiene dioxide, 1-3 parts of biuret polyisocyanate, 2-3 parts of methylisobutylketone, 4-5 parts of titanium dioxide, 3-5 parts of vermiculite powder, 2-4 parts of polyvinyl butyral, 4-6 parts of sodium hexametaphosphate, 3-5 parts of titanium dioxide, 2-4 parts of aluminum oxide, 4-5 parts of a silane coupling agent and 1-2 parts of a dispersant. On the basis of traditional electrostatic powder raw materials, the preparation raw materials of the electrostatic powder are reasonably optimized in the invention; the raw material is easy to obtain and low in cost; a coating formed after electrostatic spraying is light, thin and uniform, and has good glossiness; and meanwhile, the coating is good in adhesive force, high in hardness and goodin corrosion resistance and flame retardance, improves the use safety of the plate, and prolongs the service life of the plate.

Description

technical field [0001] The invention relates to the technical field of electrostatic spraying powder, in particular to a polymer electrostatic powder that can improve the flame-retardant performance of a board. Background technique [0002] The powder coating is sprayed onto the surface of the material to be processed by electrostatic spraying, and the non-adhesive powder particle layer is heated and melted to form a firm coating that is closely combined with the surface of the material. This coating has excellent anti-corrosion performance and decorative function. Compared with solvent-based coatings, it has the advantages of safer, less pollution, good adaptability, high efficiency and no dependence on petroleum as raw material. [0003] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various unit materials by certain mechanical processing, and glued with or without adhesives and other additives. It mainly inc...

Problems solved by technology

It mainly includes three categories of products such as plywood, particleboard and fiberboard. During the processing of the board, it is necessary to carry out electrostatic spraying treatment on the surface of the board to improve the performance of the board surface. However, in the prior art, because the raw materials prepared by electrostatic powder are relatively simple, spraying The performance of the coating formed on the surface of the plate is single, which can no longer meet the existing needs
