Problems solved by technology

[0004] Epoxy resin is an excellent anti-corrosion resin in anti-corrosion coatings, but its aging resistance and moisture resistance are generally poor; at present, the development of outdoor anti-corrosion epoxy coatings in China is slow, and there are few formulas; silicone modified resins have different prices. The difference in performance is obvious, and there are fewer mature products

Abstract

The invention discloses an epoxy polysiloxane anticorrosive paint, and belongs to the field of fine chemical paints. The epoxy polysiloxane anticorrosive paint comprises a component A and a component B in a mass ratio of 100:(13-16), wherein the component A is prepared from the following raw materials in parts by weight: 30-45 parts of epoxy resin, 5.0-10.0 parts of epoxy polysiloxane, 6.0-10.0 parts of a reactive diluent, 1.0-2.0 parts of a silane coupling agent, 0.3-0.5 part of a thickening agent, 0.4-0.6 part of a dispersing agent, 0.2-0.4 part of a flatting agent, 0.2-0.4 part of a defoaming agent, 0.4-0.6 part of a plasticizer, 1.0-3.0 parts of a diluent, 5.4-16.8 parts of pigments and 29-38 parts of a filler; the component B is a cashew nut shell oil-modified amine curing agent. The paint is greatly improved in corrosion resistance, acid resistance, alkali resistance, heat resistance, weather resistance and the like, and has excellent adhesion, flexibility, solution resistance, and the like.

Description

technical field [0001] The invention belongs to the technical field of fine chemical coatings, and in particular relates to an epoxy polysiloxane anticorrosion coating. Background technique [0002] For a long time, it has been difficult to find Chinese companies in the international first-line wind power anti-corrosion coatings and marine heavy-duty anti-corrosion coatings. In the field of offshore wind power heavy-duty anti-corrosion coatings, Chinese coating companies have retreated across the board. Facing the harsh working environment, developing high-performance coatings with good anti-corrosion and wear resistance is one of the most effective ways to solve the corrosion and abrasion problems of marine materials. At the same time, in China, every year due to metal material corrosion or local corrosion damage, equipment pipelines suddenly leak or lose strength, causing a large number of accidents and economic losses. [0003] The steady development of China's economy h...
