Abstract

The invention discloses an anti-UV irradiation silicone rubber compound and a preparation method thereof. The rubber compound consists of the following raw materials by weight: 40-60 parts of high phenyl silicone rubber, 25-45 parts of methyl MQ silicon resin, 1.5-2.5 parts of 4,4',4''-triphenylmethane triisocyanate, 5-10 parts of aluminum magnesium silicate, 3-6 parts of white factice, 2-3 parts of cobalt 2-ethylhexanoate, 2-3 parts of octamethyl cyclotetrasiloxane, 3-4 parts of tert-Butyl hydroperoxide, 3-6 parts of ethyleneglycol dimethacrylate, 2-4 parts of N,N'-dicyclohexylcarbodiimide, 10-15 parts of waste tire rubber powder, 2-3 parts of Di-t-butoxydiacetoxysilane, 8-14 parts of light calcium carbonate, 5-10 parts of glycerol tribenzoate, 4-8 parts of dipropylene glycol monosalicylate, 1-2 parts of 4-tert-butylphenol 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and 2-4 parts of an assistant. The silicone rubber compound provided by the invention has excellent anti-ultraviolet irradiation performance, good thermal stability to ultraviolet, and can be used for a long time under sunlight; and the rubber compound has excellent mechanical strength, high and low temperature resistance, corrosion resistance, electrical insulation property, long service life, wide application range and low cost.

Description

technical field [0001] The invention relates to an ultraviolet radiation-resistant silicone rubber compound and a preparation method thereof, belonging to the technical field of silicone rubber. Background technique [0002] Silicone rubber is a polymer material with polysilane as the main chain. Due to the non-polar and weak intermolecular interactions of the main chain siloxane segment, it has good thermal stability, weather resistance, aging resistance and electrical properties. Its mechanical properties are quite stable in a wide temperature range (-50~120°C), and it has been widely used in aerospace, electronic and electrical industries and other fields. Silicone rubber compounds currently on the market have the disadvantage of poor anti-ultraviolet radiation performance, and are prone to aging after long-term exposure to sunlight, resulting in short service life and unable to meet market demand. Therefore, it is necessary to modify the silicone rubber to obtain a sili...
