Abstract

An ultraviolet light-curable silicone release agent of the present invention is prepared from the following raw materials in parts by weight: 100 parts of amino silicone oil, 2-15 parts of glycidyl methacrylate, 5-100 parts of reactive diluent, and 0.1 parts of antioxidant ‑2 parts, 0‑8 parts of high viscosity methyl silicone oil, 0.1‑10 parts of photoinitiator, 100‑300 parts of solvent. The present invention also provides a preparation method for the above-mentioned organosilicon release agent. Weigh each reaction raw material according to the weight ratio, then add amino silicone oil, glycidyl methacrylate, antioxidant, and solvent into a reaction container, and after the reaction is complete, Add active diluent, high viscosity methyl silicone oil, and photoinitiator to the mixture, and then add it, and stir evenly. The silicone release agent of the present invention has a low curing temperature, and the obtained coating is transparent and colorless, can produce a good release effect, has low peeling force, and has strong resistance to water, oil and dirt, and can be applied to surfaces such as metals, ceramics, and glass. surface layer.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a coating, in particular to an ultraviolet light curing organic silicon release agent and a preparation method thereof. Background technique [0002] Silicone coating is an important direction in the field of anti-fouling coatings. Because of its low surface tension, transparency, non-toxicity, high temperature resistance, and good weather resistance, it is widely used as an antifouling coating or anti-adhesion coating on the surface of metals, ceramics, paper, plastics, and textiles. [0003] Most of the silicone coatings used in the past use vinyl silicone as the resin, hydrogen-containing silicone oil as the crosslinking agent, metal platinum as the catalyst, and cure at 130-230 °C. Due to the high curing temperature, a large amount of energy is required, and substrates that are not resistant to high temperatures such as paper and plastic may cause denaturation of the product, w...
