Preparation method of special material for injection moulding composite silicon rubber insulator mixing refine rubber

Abstract

the invention discloses a preparing method of insulator melted gel, which is characterized by the following: adopting hydroxyl silicon oil through potassium hydroxide method to replace national acetic anhydride method; utilizing dynamic high-temperature method to dispose aluminium hydroxide for flame-proof material; improving mixed property and manufacturing property of gel through associating methyl phenyl hydroxyl silicon oil and silane methyl vinyl triethoxy; fitting for injecting mould.

Description

technical field

[0001] The invention relates to the preparation technology of silicon rubber insulators, in particular to a method for preparing special mixing rubber materials for injection molding composite silicon rubber insulators by using potassium hydroxide as a catalyst. Background technique

[0002] Composite silicone rubber insulator is a new material developed rapidly in recent years. With its light weight, excellent electrical insulation and weather resistance, it is gradually replacing traditional ceramic insulators. At present, the technology used for composite silicone rubber insulators is mainly compression molding, which has low efficiency. The injection molding composite silicone rubber insulator mainly solves the fluidity of the rubber compound, which can greatly improve the production efficiency, and at the same time, the quality of the product is also greatly improved. Hydroxy silicone oil produced by the domestic acetic anhydride method is slightly acid...
