Problems solved by technology

However, the anti-corrosion performance of polyurethane is relatively poor, and the coatings made of it often cannot meet the requirements of anti-corrosion performance, and need to be modified; in addition, as an organic polymer material, polyurethane itself is easy to burn, and the coating itself made of it is easy to burn. The fire resistance performance is poor, and when it is used in wood coatings and architectural coatings, it has the defect of poor flame retardancy

Abstract

The invention discloses a flame-retardant corrosion-resistant polyurethane coating material, which comprises the following raw materials in parts by weight: 75-85 parts of polyurethane prepolymer, 15-25 parts of alkyd resin, 2-5 parts of dimethyl silicone oil, 2-5 parts of epoxy resin, 1-3.8 parts of perfluorooctanol, 0.5-1.5 parts of graphene oxide, 2-3.8 parts of nano boron carbide, 1-5 parts ofbentonite, 0.3-1.5 parts of trimethylolpropane, 0.5-1.3 parts of dipropylene glycol, 2-3 parts of paraxylene, 3-7 parts of ethyl acetate, 0.1-1 part of a silane coupling agent and 2-3.9 parts of plasticizers. The polyurethane prepolymer is prepared from diisocyanate, phosphorus-modified glycol and polyoxypropylene glycol as raw materials. The flame-retardant corrosion-resistant polyurethane coating material has high adhesive force with a basal body, good flame retardancy and excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a flame-retardant and corrosion-resistant polyurethane coating. Background technique [0002] Polyurethane coatings have excellent properties such as abrasion resistance, flexibility, adhesion and chemical resistance, and have been widely used as wood coatings, architectural coatings, automotive coatings and waterproof coatings. However, the anti-corrosion performance of polyurethane is relatively poor, and the coatings made of it often cannot meet the requirements of anti-corrosion performance, and need to be modified; in addition, as an organic polymer material, polyurethane itself is easy to burn, and the coating itself made of it is easy to burn. The fire performance of the paint is poor, and when it is used in wood coatings and architectural coatings, it has the defect of poor flame retardancy. Contents of the invention [0003] Based on the technical problems existing i...
