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.
