Abstract

The invention relates to the technical field of silicone rubber, particularly to high-hardness air-pressure-resistant silicone rubber, a preparation method and a use method thereof. The high-hardnessair-pressure-resistant silicone rubber is prepared from the following raw materials in parts by weight: 4-8 parts of hydroxyl-terminated polydimethylsiloxane, 100-115 parts of methyl vinyl silicone rubber, 60-70 parts of modified fumed silica, 1-3 parts of vinyl hydroxyl silicone oil, 0.4-0.8 part of a silane coupling agent, 0.06-0.18 part of a release agent and 0-1.5 parts of a hardening agent. According to the invention, the high-hardness air-pressure-resistant silicone rubber disclosed by the invention has very good hardness and air pressure resistance, has relatively good comprehensive properties such as viscosity, tensile strength and shrinkage rate, and can well meet the requirements of special industrial production on hardness; and the preparation method is simple, convenient to operate and control and high in production efficiency, large-scale industrial production can be achieved, the using method of the high-hardness air-pressure-resistant silicone rubber is convenient to operate and control and stable in quality, and the prepared silicone rubber product is stable in performance.

Description

technical field

[0001] The invention relates to the technical field of silicone rubber, in particular to a high-hardness air pressure-resistant silicone rubber, a preparation method and a use method thereof. Background technique

[0002] In the prior art, silicone rubber raw materials are widely used in various industries due to their superior performance, but ordinary silicone rubber raw materials are mainly composed of silicone chain links containing methyl groups and a small amount of vinyl groups, which have good oil resistance and elasticity. And tear strength, when it is applied to industry, its performance is often unsatisfactory. Unreinforced silicone rubber has extremely low strength and poor air pressure resistance, so it has no practical value, so it is used in some applications that require high hardness and air pressure resistance. Field applications are limited, so we invented a high-hardness air-resistant silicone rubber. Contents of the invention
