Polyurethane heat reflection ship hull coating

Abstract

The invention discloses polyurethane heat reflection ship hull coating, and relates to double-component acrylic polyurethane weathering heat reflection ship hull coating which can reach the film thickness requirements by generally applying one to two topcoat in coating. The film forming matters of the polyurethane heat reflection ship hull coating includes aliphatic polyurethane resin and acrylic resin, which are simultaneously added with weathering pigments and fillers and heat reflection materials so that various mechanical physical performances and weathering performances of the coating are greatly improved. The coating is double-component acrylic polyurethane corrosion protective coating, including acrylic resin, polyurethane resin, plasticizers, heat reflection material, pigments and fillers, imported dispersants, anti-sedimentation agents, and the like; and the weight ratio of A component and B component is 8:1. The coating has very excellent aging resistant performance, hard coating film, high glossiness and strong adhesion force, can achieve good external corrosion prevention effect, and is widely used in steel structures, pipelines, storage tanks, tank cars and equipment in the industries such as the chemical engineering, the machinery, the ship, the metallurgy and the like as the surface corrosion prevention coating.

Description

technical field [0001] The invention relates to an external anti-corrosion finish paint, in particular to a two-component acrylic polyurethane heat-reflecting ship hull paint which is suitable for the outer surface of a steel structure and has excellent weather resistance and heat reflection function. Background technique [0002] In steel structure anti-corrosion engineering, coating has always been the most important, most economical and effective anti-corrosion method. At present, the corrosion of ships and general steel structures is mainly manifested in the damage of internal structures and parts exposed to atmospheric environments such as sunlight and salt spray. Alkyd and epoxy ester antirust primers are mainly used for domestic maintenance of steel structures and cabins, while alkyd paints are mostly used for shell parts. Due to their poor water resistance, weather resistance, and chemical resistance, these types of antirust paints and topcoats have a protection per...

Problems solved by technology

[0004] At present, a small number of manufacturers in China have produced acrylic polyurethane two-component coatings, but the supporting coatings for harsh environments such as high humidity, high salt spray, long-term sunlight exposure and heat reflection function are still blank.
