Embodiment 1

[0013] A high-strength insulator silica gel and a preparation method thereof, the preparation method is as follows; first add 100 parts of methyl vinyl raw rubber with a vinyl molar content of 0.2% in a kneader, and stir for 2-4 minutes; mix 50 parts of white Carbon black, 400 parts of aluminum hydroxide, 2 parts of stearic acid 1801, 4 parts of hydroxy silicone oil and 4 parts of vinyltriethoxysilane were added in several times, and fully stirred after each addition to obtain a silicone rubber mixture; kneading After molding, the temperature is raised to 150°C, cooled to 80°C with cooling water, and the glue is produced to obtain the mixed silicone rubber; after the glue is produced, it is cooled to room temperature to obtain the product.

[0014] Vulcanizing agent can be added to vulcanize during use, vulcanized at 170 degrees Celsius for 5 minutes, and secondary vulcanized at 200 degrees Celsius for 4 hours.

Embodiment 2

[0016] A high-strength insulator silica gel and a preparation method thereof, the preparation method is as follows; first add 100 parts of methyl vinyl raw rubber with a vinyl molar content of 0.2% in a kneader, and stir for 2-4 minutes; mix 60 parts of white Carbon black, 300 parts of aluminum hydroxide, 3 parts of stearic acid 1801, 3 parts of hydroxy silicone oil and 3 parts of vinyltriethoxysilane were added in several times, and fully stirred after each addition to obtain a silicone rubber mixture; kneading After molding, the temperature is raised to 150°C, cooled to 80°C with cooling water, and the glue is produced to obtain the mixed silicone rubber; after the glue is produced, it is cooled to room temperature to obtain the product.

[0017] Vulcanizing agent can be added to vulcanize during use, vulcanized at 170 degrees Celsius for 5 minutes, and secondary vulcanized at 200 degrees Celsius for 4 hours.

Abstract

The invention discloses a high-strength insulator silica gel and a preparation method thereof. The high-strength insulator silica gel comprises crude rubber, precipitated silica, aluminium hydroxide, hydroxyl silicone oil, vinyltriethoxysilane, stearic acid and the like. The ingredients above are mixed by a kneader. The high-strength insulator silica gel possesses high strength and hardness, and excellent processability; is difficult to distort; is capable of meeting the requirements of an composite insulator; and has a wider application range.

Description

technical field [0001] The invention relates to the manufacture of silicone rubber materials, in particular to a high-strength insulator silica gel and a preparation method thereof, belonging to the field of rubber material manufacture. Background technique [0002] Silicone rubber has many excellent properties such as good high and low temperature resistance, ozone resistance, weather resistance, insulation and production inertia, and is widely used in various fields of the national economy. The characteristics of silicone rubber itself and its excellent processing and forming properties determine that it has the conditions to become the material for making insulators. But to be applied to insulators, the strength of silicone rubber is difficult to meet the requirements of insulators. Therefore, it is very positive to study high-strength insulator silicone. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art...
