Discussion on the chemical composition and the basic process of rubber configuration.

Release date:2017-10-11 Author: Click:

Based on the analysis of the chemical composition of natural rubber, it is found that the basic composition of isoprene is isoprene. It was inspired by the polymerization of isoprene as monomer, and the synthetic rubber, called isoprene rubber, was obtained. The structure and properties of isoprene rubber are basically the same as those of natural rubber. Because isoprene was only obtained from turpentine, the sources of raw materials were limited, and butadiene was abundant. Therefore, a series of synthetic rubbers were developed based on butadiene. Such as polybutadiene rubber, styrene butadiene rubber, nitrile rubber and chloroprene rubber etc..

With the development of petroleum chemical industry, from the oil field gas and refinery gas by pyrolysis and purification, can obtain ethylene and propylene, butene and butane, isobutene, pentene, isoprene and other gases, which is a good material for the manufacture of synthetic rubber. Natural rubber accounts for only about 15% of the world's rubber production, and the rest are synthetic rubber. There are many kinds of synthetic rubber with different properties, which can replace or even surpass natural rubber in many occasions. Synthetic rubber can be divided into general rubber and special rubber. General large amount of rubber, such as styrene butadiene rubber synthetic rubber production accounted for 60%; followed by butadiene rubber, accounted for 15%; in addition, isoamyl rubber, chloroprene rubber, nitrile, ethylene propylene rubber, butyl rubber and so on, they all belong to the general rubber.

The preparation of rubber raw materials can be divided into three basic processes.

1.: Plastic plastication practice is gum cut, and rubber can be plasticized, homogenization, help a complexing agent mixing operation. The effect is to improve the dispersion of drugs, to prevent the friction heat generated in operation, and miscellaneous pieces of silicone rubber scorch phenomenon occurs, and then change the processing of rubber.

2. mixing: mixing with drug is uniformly mixed in the finished rubber plastication, and mixing quality, directly affect the products of good or not. Drugs are unevenly distributed, the molecular structure can not be completely crosslinked, miscellaneous pieces of silicone rubber are unable to reach the ideal.

3. out: complete mixing of raw rubber, after extrusion operation, the excess air pressure containing compound, and complete the required thickness, in order to facilitate the mold operation.

Dongguan strong rubber products Co., Ltd. is a private science and technology enterprise founded in May 2004. Factory formerly known as: Dongguan Hechuan rubber products factory in Sha tin. Due to the expansion of the company, in October 2010, the factory moved to Liang Jia Town, Dongguan Town, Shijie, the factory changed its name to: Dongguan strong rubber products Co., ltd.. The company specializing in the production of miscellaneous pieces of silicone rubber, silicone keypad, sealing ring, foot pad; the bell color EVA, foam, EPE; various kinds of imported double-sided adhesive; various insulating materials; all kinds of stamping products; products such as screen printing nameplate.
