Abstract

The invention relates to a water-based polyurethane enamel paint which is prepared by mixing a component A and a component B in a weight ratio of 7:1, wherein the component A comprises the following components in parts by weight: 100 parts of water-based acrylic grafted polyurethane emulsion, 20-28 parts of pigment, 10-20 parts of functional filler, 0.2-0.5 part of rheological agent, 0.1-0.5 part of wetting dispersant, 0.1-0.5 part of substrate wetting agent, 0.2-0.5 part of anti-settling agent, 0.2-0.5 part of defoaming agent, 0.2-0.5 part of thickening agent and 0.1-0.5 part of leveling agent; and the component B comprises the following components in parts by weight: 10-15 parts of isocyanate and 10-15 parts of dipropylene glycol dimethyl ether. The enamel paint is used on the surface of a rubber tube in an airplane and other non-metal composite materials, and has the advantages of short drying time, strong adhesive force, medium resistance, bending resistance, flame retardancy, favorable high/low temperature resistance, no adverse effect on the substrate and the like.

Description

technical field [0001] The invention relates to a water-based polyurethane enamel, which is suitable for the surface of non-metallic composite materials such as rubber tubes. Background technique [0002] In recent years, major developed countries in Europe and the United States have higher and higher environmental protection requirements for aircraft coatings, and have passed legislation to limit VOC emissions and heavy metal consumption. Water-based coatings are the development trend of coatings, and so are aircraft coatings. Traditional solvent-based coatings used for aircraft cabin parts contain a large amount of organic solvents, which not only pollute the environment, pose fire hazards, but also seriously damage the health of construction workers. [0003] Coatings for aircraft interior parts have been developed abroad. They are not only low-toxic and environmentally friendly, but also have outstanding adhesion, flexibility, flame retardancy and excellent decoration. T...
