Abstract

The invention discloses an ultraviolet light curing type antifouling, toughening and high temperature resistant coating and a preparation method thereof. The coating comprises the following components in mass percentage: 10-40% of aliphatic polyurethane acrylic (ester) resin, functional I acrylic monomer 5-25%, functional II acrylic monomer 5-25%, reactive diluent 5-25%, organic solvent 10-40%, photoinitiator 0.5-3%, other additives 0.5-10%. The antifouling, toughening and high temperature resistant coating of the present invention has good hydrophobicity and oil repellency, high temperature resistance, toughness and gloss, and the coating adopts UV curing type, does not need high temperature heating, and is suitable for a wide range of substrates; it is environmentally friendly, pollution-free, and has a short curing time , conducive to industrial production.

Description

technical field [0001] The invention relates to the field of ultraviolet light curing coatings, in particular to an ultraviolet light curing antifouling toughening high temperature resistant coating and a preparation method thereof. Background technique [0002] In daily life, most products such as metal profiles, glass products, plastic products and other products are covered with a layer of plastic film, such as PVC film, to protect the surface of the product. However, according to the application scenarios and performance requirements of different products, it is difficult for ordinary plastic protective films to meet the functions of customers' individual needs. Therefore, based on the basic performance of "protecting the surface", endowing the protective film with auxiliary properties such as antifouling, toughening, UV resistance, high temperature resistance, and aging resistance plays an important role in protecting products. Contents of the invention [0003] The ...
