 Organic compounds, synthetic rubber


There are two main methods for the synthesis of rubber by organic compounds: the synthesis of natural rubber and the method of synthetic rubber.


1. Synthesis of natural rubber: natural rubber is a polymer organic compound produced by rubber trees, and the main component is polymer isoprene (polyisoprene). The emulsion that flows through the cut wounds of the rubber tree is treated and processed to obtain pure rubber.


2. Methods of synthetic rubber: synthetic rubber is mainly obtained by chemical synthesis. The most common method of synthetic rubber is polymerization, that is, the polymerization reaction of monomer compounds to form polymer compounds, so as to obtain rubber materials. Here are some common methods of synthetic rubber:


Styrene-butadiene rubber (BR): copolymerization of butadiene and styrene in the presence of a catalyst;


Butadiene rubber (SBR): copolymerization of styrene-butadiene rubber and acrylonitrile in the presence of a catalyst;


Nitrile rubber (NBR): copolymerization of butadiene and acrylonitrile in the presence of a catalyst;


Ethylene propylene monomer (EPDM): ethylene, propylene and non-conjugated diene are polymerized at high temperatures;


Neoprene (CR): Copolymerization of butadiene and vinyl chloride in the presence of a catalyst.


These synthetic rubbers can obtain rubber materials with different properties and uses through different monomer combinations and polymerization reaction conditions. Compared with natural rubber, synthetic rubber has a wider range of controllability and customization, and is suitable for application needs in various fields.

 

 The characteristics of flame retardant rubber for electrical and electronic appliances include:


1. Flame retardant performance: Flame retardant rubber has self-extinguishing performance, which can prevent the further spread of fire and reduce the risk of fire when it is exposed to fire sources. It inhibits the spread of flames and smoke, reducing the release of toxic gases.


2. Electrical insulation performance: flame retardant rubber has good electrical insulation performance, which can effectively insulate and protect electronic and electrical equipment, and prevent current leakage and electric shock risk.


3. High temperature resistance: flame retardant rubber can maintain stable performance in high temperature environment, not easy to melt and deform, and provide reliable protection.


4. Chemical resistance: flame retardant rubber has good resistance to most chemical substances, is not easy to be corroded and dissolved, and can be used in harsh chemical environments.


5. Good flexibility and elasticity: flame retardant rubber has good flexibility and elasticity, which can adapt to electronic and electrical equipment of different shapes and sizes, providing effective protection and sealing.


It should be noted that the specific characteristics and specifications of flame retardant rubber for electrical and electronic appliances may vary depending on the product model, manufacturer and material formulation. In applications, the use of suitable flame retardant rubber materials can improve the safety and reliability of electrical and electronic equipment.
