Abstract

The invention discloses a sand texture type polyester / epoxy powder coating and a preparation method thereof. The sand texture type polyester / epoxy powder coating comprises the following raw materials, by weight, 350-400 parts of polyester resin (P5040), 240-280 parts of epoxy resin (E-12), 100-150 parts of extinction barium sulfate, 40-60 parts of spherical silica powder, 8-12 parts of modified polyethylene wax powder, 10-15 parts of organic coated titanium dioxide, 5-10 parts of sand texture agent (SWMBX-30), 4-6 parts of benzoin, 5-8 parts of 2-phenyl imidazoline, 4-6 parts of 2-methylimidazole, 5-10 parts of ferrite yellow, 5-10 parts of iron oxide red and 10-15 parts of carbon black. The prepared powder coating has the advantages of being high in hardness, high in intensity, high in abrasion resistance, good in heat resistance, good in ageing resistance, short in solidifying time, environment-friendly, free of pollution and the like. The solidified coating produces a texture effect of the sand texture, the sand texture is meticulous and clear, distribution is even, visual comfort is provided for people, and combination properties of the coating are good.

Description

technical field [0001] The invention relates to a powder coating, in particular to a sand grain type polyester / epoxy powder coating and a preparation method thereof. Background technique [0002] As an environmentally friendly coating, powder coating has the advantages of no solvent, low pollution, simple coating process and high coating efficiency. The surface of the powder coating commonly used at present is flat, dull, poor in hand feeling and lacks three-dimensional effect after curing. With the rapid development of the powder coating industry, people are no longer satisfied with the monotonous gloss or color-changing decoration of various home appliances and equipment to be coated. The art-type powder coating has a beautiful and clear appearance on the surface of the coating film. Patterns, to give the coated device a beautiful and colorful appearance, or to cover up the defects on the surface of the coated object by its texture effect, so as to improve the decorativen...
