Abstract

The invention discloses a compression deformation resistant and high hardness foam silicone rubber material and preparation method thereof. The foam silicone rubber material is made of component A andcomponent B which are of equal mass, wherein the component A includes, by mass ratio, 100 parts of liquid silicone rubber, 0.5 to 2 parts of foaming agents, 15 to 45 parts of aids, 0.25 to 2 parts ofcatalysts, and 1 to 5 parts of colorants, and component B includes, by mass ratio, 100 parts of liquid silicone rubber, 0.5 to 2 parts of foaming agents, 25 to 55 parts of aids, 1 to 5 parts of crosslinking agents, and 0.5 to 2 parts of inhibitors. The compression deformation resistant and high hardness foam silicone rubber material has the advantages of having good thermal insulation, high hardness, delicate cells of a closed-cell structure and good compression set performance, being capable of not only providing a good cushioning effect when the device is impacted but also being used as aninsulating product to retard thermal diffusion, and reducing the risk in life.

Description

technical field [0001] The invention relates to a silicone rubber foam material and a preparation method thereof, in particular to a compression-resistant high-hardness foam silicone rubber material and a preparation method thereof. Background technique [0002] Silicone rubber foam material is a multifunctional polymer elastomer prepared by foaming in a certain way based on silicone rubber. It not only retains the excellent properties of silicone rubber itself, such as insulation, weather resistance, and corrosion resistance, but also has the characteristics of foam materials such as light weight, heat insulation, shock absorption, shock resistance, and impact resistance, so it is used as a high-performance material such as heat insulation, shock absorption, etc. Widely used in automotive, national defense, aerospace and other cutting-edge fields. [0003] According to the vulcanization method, silicone rubber foam materials can be divided into two categories: thermal vulc...
