Powdery paint containing nano-attapulgite and preparation method thereof

Abstract

The invention discloses powdery paint containing nano-attapulgite and a preparation method thereof. The powder paint comprises the following raw materials: an epoxidized polybutadiene resin, a rosin resin, nano-attapulgite, polyethylene glycol, dimethylimidazole, bronze red pwder, hollow glass beads, ultramicro-wax-powder, isooctyl polyethenoxy ether, an anti-oxidant 565, tributyl citrate, chitosan, and a film forming resin. The powder paint provided by the invention is green environment-friendly type paint, and has the characteristics of nontoxicity, high temperature resistance, no solvent contained, and no VOC emission; by adopting an epoxidized polybutadiene resin as a main raw material and adding in a film-forming resin and nano-attapulgite, the film-forming ability of the powder paint is enhanced, the surface levelling property of the powder paint is improved, high gloss retention is achieved, and the decorative quality of the powder paint is improved; and qualified rates of prepared finished products are high, and industrialized mass production can be realized.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a powder coating containing nano-attapulgite 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, cracking, peel...
