First, the necessity of rubber flame retardant
With the continuous advancement of science and technology, rubber products have been widely used in all walks of life. Wires and cables, rubber ropes, conveyor belts, hoses, air ducts, rubber belts, and rubber products used in the electrical and electronic industries must meet the corresponding national standards in terms of flame retardant properties and mechanical properties. The requirements for the flame retardant properties of rubber products are also getting higher and higher, and the development and application of flame retardant rubber has become particularly important.
Two, several important ways of rubber flame retardant
The main way of flame retardant is to slow down thermal decomposition and block the combustion process. The specific ways of flame retardant are as follows:
1. Add one or several substances to change the thermal decomposition behavior of the rubber, make the thermal decomposition temperature of the prepared rubber higher, and reduce the flammable gas generated by the decomposition.
2. The added substances can generate non-combustible gas when heated, or produce viscous substances that isolate O2, or absorb heat when heated, so that the three elements of combustion (combustibles, oxygen, and reaching the ignition point) cannot be satisfied.
3. Add substances that can capture HO• to interrupt the chain reaction and stop the flame propagation.
4. Change the structure or properties of the rubber molecular chain, improve the thermal decomposition ability or make it flame retardant.
Due to the good compatibility between rubber and various additives, the addition of various flame retardants is still an important means of rubber flame retardant modification.
Rubber flame retardant is an inevitable trend of scientific and technological development. With the development of the market, rubber flame retardants will have better market and application prospects. We will continue to innovate, continue to research new and efficient flame retardants, and prepare flame retardant rubber with better comprehensive properties through experiments.
