Anti-corrosion antirust powder paint

Abstract

The invention discloses anti-corrosion antirust powder paint belonging to the technical field of powder paint of electrostatic coatings. The anti-corrosion antirust powder paint is prepared by the following common raw materials of powder paint in general proportion: epoxy resin, indoor polyester resin, a flatting agent, a degasifying agent, a flexibilizer, a flow promoter, fillings, and the like. The preparation method is carried out by adopting the prior powder paint production technology, and the formulation comprises composite iron-titanium powder and sheet zinc powder which are respectively 10-40 percent and 0-10 percent of the gross weight of the raw materials. The anti-corrosion antirust powder paint does not contain toxic raw materials limited to use, is suitable for the surfaces of steel and iron components treated in various pretreatment modes, and has favorable anti-corrosion antirust performance of the coatings, lower product cost than zinc-based heavy-duty anticorrosive powder paint, favorable performance price ratio and remarkable economic and social benefits.

Description

technical field [0001] The invention relates to an anti-corrosion and anti-rust powder coating, which belongs to the technical field of electrostatic coating powder coatings. Background technique [0002] Anti-corrosion and anti-rust powder coatings are one of the development trends of powder coatings. At the beginning, anti-corrosion powder coatings mainly improve the anti-corrosion ability of powder coatings by using base resin and anti-rust pigments and fillers. For higher anti-corrosion requirements, thick coating and multi-coating are adopted. The construction method of multi-layer or composite coating is used to achieve the anti-corrosion purpose of the coating. The commonly used anti-rust pigments are mainly red lead, zinc powder and aluminum tripolyphosphate. With the strengthening of social environmental protection awareness, the use of red lead is gradually restricted due to its high lead content and great social harm. The production and use of paints containing re...
