Abstract

The invention relates to a high pressure steam impact resistant coating for metal materials and a preparation method of the coating. The coating is prepared from the following components in parts by weight: A) 10-40 parts of silicone-modified acrylic resin, B) 10-40 parts of hydroxy acrylic polyol resin, C) 1-20 parts of hydrolyzable organosiloxane resin, D) 0-30 parts of pigments and fillers, E)0.1-10 parts of an organophosphorus compound stabilizer, F) 0.1-10 parts of an organic phenolic antioxidant, G) 0.1-10 parts of additives such as a wetting leveling agent and the like, H) 1-40 parts of an organic solvent and I) a cross-linking agent. Compared with the prior art, the coating has excellent adhesion, water resistance, high pressure steam washing resistance and other film forming properties to metal materials. According to the needs of model design, the glossiness of a coating film is adjustable, and the coating is excellent in resistance to various chemicals, has an adjustable design appearance, is especially suitable for automotive exterior parts used in cold areas, and has the advantages of corrosion resistance, warm water resistance, high pressure steam impact resistance and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating for high-pressure steam shock-resistant metal materials and a preparation method thereof. Background technique [0002] In the cold regions of Europe, America and Northeast my country, high-temperature steam is often used to shock and wash cars in winter. High-pressure steam can not only sterilize, but also decontaminate. It has a unique thermal decomposition function, which can quickly dissolve the sticky nature of frozen ice, sediment and stains, so that it can be separated from the surface of the attached car paint film to achieve the purpose of cleaning . However, because the steam temperature used in high-temperature steam car washing is too high, excessive pressure will increase the high-temperature and high-pressure impact resistance of the car paint film. Long-term high-temperature and high-pressure steam impact car washing will cause the protective paint film...
