Powder coating containing modified sepiolite powder and preparing method thereof

Abstract

The invention discloses a powder coating containing modified sepiolite powder and a preparing method thereof. The powder coating containing the modified sepiolite powder is composed of raw materials comprising modified epoxy resin, bisphenol S epoxy resin, linear low density polyethylene resin, modified sepiolite powder, polyethylene wax, film forming resin, polydimethylsiloxane, benzoin, silver powder, acrylic resin, superfine talcum powder, hexamine, 2,6-di-tert-butyl-4- dimethylamino methyl) phenol, n-butyl methacrylate and polyacrylamide. The powder coating is a green and environment-friendly coating, nontoxic and heat-resistant, contains no solvent, and discharges no volatile organic compound (VOC), and furthermore the modified sepiolite added in the powder coating enhances compatibility of the modified epoxy resin, the bisphenol S epoxy resin and the linear low density polyethylene resin, improves surface leveling of the powder coating, has high gloss retention, and enhances decorating performance of the powder coating, and therefore, an obtained finished product is high in pass percent, and industrialization mass production can be achieved.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a powder coating containing modified sepiolite powder and a preparation method thereof. Background technique [0002] With the continuous and stable growth of my country's economy and the continuous improvement of people's living standards, the powder coating business of metal components is also increasing, especially in industries such as household appliances, instruments and meters, transportation facilities, aluminum profiles, various vehicles, and daily hardware. , powder coating can provide metal with excellent anti-corrosion protection and decorative properties, but due to the unsatisfactory anti-pollution performance of existing coatings used in the above-mentioned fields, various types of dust, dirt and even oil are often attached to the coating; anti-sticking ability It is also not ideal, and the coating formed by the existing powder coating is prone to blistering, crack...
