Problems solved by technology

However, if the fluorocarbon resin is directly mixed with other resins, the compatibility of the fluorocarbon resin and other resins in the obtained thermosetting powder coating is not good, resulting in poor stability of the coating; and the amount of fluorocarbon resin in this coating is large, The cost is still high, which is not conducive to the promotion and application of fluorocarbon coatings

Abstract

The invention relates to an anti-corrosion thermosetting powder coating. The anti-corrosion thermosetting powder coating is composed of raw materials including, by weight part, 20-40 parts of perfluoroalkylpolyether modified polyester resin, 20-40 parts of epoxy resin, 5-10 parts of FEVE (fluoroethylene vinyl ether) fluorocarbon resin, 4-10 parts of curing agent, 0.2-1 part of catalyst, 0.3-2 parts of rutile nano-titanium dioxide, 15-30 parts of kieselguhr, 15-30 parts of barium sulfate, 0.5-2 parts of leveling agent, 0.1-0.8 part of pigment and 0.1-0.5 part of degassing agent. The anti-corrosion thermosetting powder coating compounds the perfluoroalkylpolyether modified polyester resin, the epoxy resin and the FEVE fluorocarbon resin to achieve high corrosion resistance, high adhesive force and good wettability.

Description

technical field [0001] The invention belongs to the field of thermosetting powder coatings, in particular, the invention relates to a corrosion-resistant thermosetting powder coating. Background technique [0002] Thermosetting powder coatings have become the "4E type" (high production efficiency, excellent coating performance, Eco-friendly, economical) coatings. At present, it is mainly used in metal coating, household appliances, automobiles, aluminum materials and other fields. According to statistics, the consumption of thermosetting powder coatings in my country was 1.05 million tons in 2012, 1.12 million tons in 2013, 1.24 million tons in 2014, 1.35 million tons in 2015, and 1.42 million tons in 2016. The annual sales volume reaches 1.605 million tons, showing an increasing trend year by year. Thermosetting powder coatings mainly include epoxy resin powder coatings, polyester powder coatings, polyurethane powder coatings, acrylic powder coatings, fluorocarbon powder ...
