Antifouling organosilicon paint and preparation method thereof

Abstract

The invention relates to an antifouling organosilicon paint and a preparation method thereof. The antifouling organosilicon paint is prepared from the following raw materials in parts by weight: 20-50 parts of amino silicon oil, 0.1-10 parts of polyfunctional epoxy compound, 0.1-2 parts of tert-butyl hydroquinone, 1-5 parts of methyl silicon oil and 50-100 parts of solvent. The invention provides a preparation method of the organosilicon paint, which comprises the following steps: adding the amino silicon oil, polyfunctional epoxy compound, methyl silicon oil, tert-butyl hydroquinone and solvent into a reaction vessel according to parts by weight, and uniformly mixing to obtain the antifouling organosilicon paint. The paint can be cured at normal temperature. The obtained coating is transparent and colorless, can generate favorable anti-adhesion effect and low stripping force, has the advantages of high water / oil fouling resistance and low surface tension, is applicable to external surfaces of metals, ceramics, glass, textiles, paper, wood products and the like, and has wide application range.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a coating, in particular to an anti-sticking organic silicon coating and a preparation method thereof. Background technique [0002] Silicone coatings are 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, some heat-labile materials such as paper and plastic are prone to changes in material composition, color or shape when heated, and their applications are limited. The reaction b...
