Problems solved by technology

There are many fillers used to fill silicone rubber in the market. Although ordinary mineral fillers are cheap, they will greatly reduce the physical properties of the product after being filled in silicone rubber products. The commonly used white carbon black in silicon rubber Better physical properties can be obtained in rubber, but granular white carbon black has limited improvement in the tearing and processing properties of silicone rubber

Abstract

The invention discloses a silicon rubber material containing a titanate component. The silicon rubber material containing the titanate component is prepared from, by weight, 100 parts of silicon rubber and 1-50 parts of titanate, wherein titanate is fiber potassium titanate or flake potassium titanate. The silicon rubber material is reasonable in design and easy to prepare, the processing performance of a silicon rubber compound is not changed, a silicon rubber system is filled with a certain quantity of potassium titanate fibers subjected to surface treatment or potassium titanate fibers without surface treatment, the tensile strength of a silicon rubber product is increased by 10%, and the splitting and tearing strength of the silicon rubber product is increased by 30%-100%; meanwhile, the high-temperature resistance of the rubber material can be obviously improved, the elongation of the silicon rubber can also be reduced, and the rigidness of the extruded silicon rubber product can be improved.

Description

technical field [0001] The invention relates to the technical field of silicone rubber materials, in particular to a silicone rubber material containing titanate components that can improve the material performance and heat resistance of the silicone rubber material. Background technique [0002] With the development of social industry, the requirements for silicone rubber products are becoming more and more stringent. Nowadays, people are eager for silicone rubber products, especially white and light-colored products, to have better tear strength and tear resistance, and have better Heat resistance and good processability. There are many fillers used to fill silicone rubber in the market. Although ordinary mineral fillers are cheap, they will greatly reduce the physical properties of the product after being filled in silicone rubber products. The commonly used white carbon black in silicon rubber Better physical properties can be obtained in rubber, but granular white carb...
