Description

technical field [0001] The invention relates to the technical field of rubber preparation, in particular to a preparation process of conductive rubber. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber belongs to completely amorphous polymer, its glass transition temperature is low, its molecular weight is often very large, more than hundreds of thousands, but the existing technology should make rubber have good physical and chemical properties, with strong heat resistance, water resistance, corrosion resistance, The characteristics of anti-aging and other aspects, then in the production process of rubber products, the requirements for its production technology are relatively high, and the production and preparation methods of rubber are relatively c...

Rubber belongs to completely amorphous polymer, its glass transition temperature is low, its molecular weight is often very large, more than hundreds of thousands, but the existing technology should make rubber have good physical and chemical properties, with strong heat resistance, water resistance, corrosion resistance, The characteristics of anti-aging and other aspects, then in the production process of rubber products, the requirements for its production technology are relatively high, and the production and preparation methods of rubber are relatively complicated, the production pollution is serious and the preparation rate is low. The thermoplastic rubber developed in the 1960s Rubber does not require chemical vulcanization, but is formed by thermoplastic processing methods. Rubber is divided into two types: general-purpose and special-type according to use. It is an insulator and is not easy to conduct electricity. However, if it is exposed to water or at different temperatures, it may become Conductor, conduction refers to the easy conduction of molecules or ions inside the substance. The molecular chains of rubber can be cross-linked. When the cross-linked rubber is deformed by external force, it has the ability to recover quickly and has good physical and mechanical properties. And chemical stability, rubber is the basic raw material of the rubber industry, widely used in the manufacture of tires, rubber hoses, tapes, cables and other various rubber products, rubber is divided into natural rubber and synthetic rubber according to raw materials, and divided into block raw rubber according to shape , latex, liquid rubber and powder rubber. Latex is a colloidal water dispersion of rubber. Liquid rubber is an oligomer of rubber. It is generally a viscous liquid before vulcanization. Powder rubber is to process latex into powder to facilitate Ingredients and Processing
