Product Description

Since the industrial production of butyl rubber, the raw material route, production process and the structure of polymerization kettle have not changed much. Generally, methyl chloride is used as diluent and aluminum trichloride is used as catalyst. The monomer conversion can be adjusted by controlling the amount of these two. The polymerization of butyl rubber is carried out by positive ion reaction. The reaction temperature is low, the reaction speed is fast, the exothermic heat is concentrated, and the molecular weight of the polymer decreases sharply with the increase of temperature. Therefore, it is the main problem in production to rapidly discharge the polymerization heat to control the reaction at a constant low temperature.



The polymerization kettle is a tubular reactor with a large heat transfer area and a central tube. During operation, the internal circulation volume is increased by the high-speed rotation of the lower agitator, so as to ensure the uniform temperature at all points in the kettle. After halogenation, the curing rate of butyl rubber is greatly increased, the blending and curing properties with other rubbers are improved, and the adhesion is also significantly improved. Halogenated butyl rubber is especially suitable for making inner sealing layer of tubeless tire, sidewall and adhesive of radial tire, in addition to general use of butyl rubber.

Butyl rubber has good air tightness. It also has heat resistance, ozone resistance, aging resistance, chemical resistance, shock absorption and electrical insulation properties. It has good resistance to sunlight and ozone, and can be exposed to animal or vegetable oil or oxidizable chemicals. The inner tube of all kinds of tires, the airtight layer of tubeless tires, and various sealing gaskets are used as the lining, pipeline, and conveyor belt of corrosive liquid containers in the chemical industry, and as waterproof materials in agriculture.
