Problems solved by technology

However, silicone rubber has poor mechanical properties such as tensile strength and tear resistance. At room temperature, its physical and mechanical properties are inferior to most synthetic rubbers, and its oil resistance and solvent resistance are also poor, so it cannot be used in other synthetic rubbers. use in case of

Embodiment Construction

[0011] The technical solutions of the present invention are described below through specific examples.

[0012] Included in the technical scheme of the present invention, a kind of silica gel modified material composition, wherein, by accounting for the white carbon black of described composition gross weight 5-9%, the quartz of 50-80% or CaCO 3 , 0.5-4.0% process acid, 4.0-9.0% acid acceptor or oil resistant compounding agent, 1.0-3.0% filler, 0.8-2.5% heat stabilizer, 2.0-5.0% peroxide, 0.5- 2.0% hardener, 0.5-1.5% plasticizer.

[0013] In the above technical solution, the specific gravity of quartz or calcium carbonate can be increased under certain conditions to reduce the overall cost. Acid acceptors improve compression set and stability by eliminating the need for pre-vulcanization of the product. Other compounding agents can increase the impact on properties such as thermal stability, dielectric strength, conductivity and adhesion. The above formulation simplifies th...

Abstract

The invention provides a silicone rubber modified material composition and an application thereof. The composition consists of the following components in percentage by weight: white carbon black which accounts for 5-9% of the total weight of the composition, 50-80% of quartz or CaCO3, 0.5-4.0% of process acid, 4.0-9.0% of acid receptor or oil-resistant compounding agent, 1.0-3.0% of filling agent, 0.8-2.5% of thermal stabilizer, 2.0-5.0% of peroxide, 0.5-2.0% of hardening agent and 0.5-1.5% of plasticizer. The invention also provides the application of the silicone rubber modified material composition in silicone rubber mixing. By implementing the technical scheme, the silicone rubber modified material composition provided by the invention can obtain the technical effects as follows: the tensile strength and tearing strength of silicone rubber can be improved, and the oil resistance and solvent resistance properties of the silicone rubber can be improved.

Description

technical field [0001] The invention relates to a chemical preparation, in particular to a silica gel modified material composition and its application.
