Problems solved by technology

For example, the refrigerator liner, end cover and fruit and vegetable boxes are mostly made of acrylonitrile-butadiene-styrene copolymer ABS, impact-resistant polystyrene HIPS or general-purpose polystyrene GPPS, which have a large surface energy and are easy to absorb oil stains It is difficult to clean; in addition, this kind of material also has problems such as low hardness, easy to scratch, and easy to crack and age when it is in contact with food oil for a long time.

Abstract

The invention relates to an easy-to-clean coating and a preparation method and application thereof. The easy-to-clean coating comprises the following components in parts by weight: 20 to 30 parts of fluorosilicone modified acrylic resin, 10 to 20 parts of urethane acrylate, 0.5 to 7 parts of a dispersing agent, 23 to 60 parts of a solvent and 0.7 to 1.5 parts of a curing agent. The preparation method comprises the following steps: 1) adding the fluorosilicone modified acrylic resin into the solvent, carrying out uniform mixing, and adding the urethane acrylate to obtain a mixed solution; 2) sequentially adding the dispersing agent and the solvent into the mixed solution and carrying out uniform mixing; and 3) finally, adding the curing agent until the curing agent is completely dissolved to obtain the easy-to-clean coating. The easy-to-clean coating disclosed by the invention has the advantages of good adhesive force, high wear resistance, good toughness, aging resistance and the like,and is low in cost and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an easy-to-clean coating and a preparation method and application thereof. Background technique [0002] With the rapid development of science and technology, the application and research of engineering plastics are becoming more and more extensive. Compared with other materials, its performance in all aspects has reached a higher standard, and it has been widely used in household appliances. However, due to the working environment of different household appliances, there are also some special functional requirements for engineering plastics. For example, the refrigerator liner, end cover and fruit and vegetable boxes are mostly made of acrylonitrile-butadiene-styrene copolymer ABS, impact-resistant polystyrene HIPS or general-purpose polystyrene GPPS, which have a large surface energy and are easy to absorb oil stains It is difficult to clean; in addition, this kind of material also ha...
