Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a high-strength and high-toughness modified silicone rubber material. Background technique [0002] Silicone rubber refers to the rubber whose main chain is composed of silicon and oxygen atoms alternately, and there are usually two organic groups attached to the silicon atoms. Silicone rubber has good low temperature resistance, and the heat resistance of silicone rubber is also outstanding. Silicone rubber has high temperature stability. Although the strength of silicone rubber at room temperature is only half of that of natural rubber or some synthetic rubber, it can be used at high temperatures above 200°C. Under environmental conditions, silicone rubber can still maintain a certain degree of flexibility, resilience and surface hardness. Silicone rubber has good air permeability, and its oxygen transmission rate is the highest among synthetic polymers. In addition, silicone ...
