Or isolate the source of fire, to extend the ignition time of the substrate, or to postpone structural damage time increased insulation properties
Paint the general term, it belongs to the special functional coatings. Many plastics such as polyethylene, polystyrene and polypropylene thermoplastic
And unsaturated polyester a vinegar thermosetting plastic is easy to burn, it is necessary to take effective measures to prevent burning.
Combustion is an exothermic oxidation reaction, it must meet three conditions, may be combustible substance, the oxidizer (air or
Oxygen) and sources of ignition (flame or heat), these three conditions at least one combustion will not occur or blocked. Burn
Burned release a lot of heat, heat conduction the surrounding combustible thermal decomposition, resulting in the spread of combustion. Flame retardant
Nothing less than the destruction of any one of the burning conditions, such as adding an inorganic filler such as calcium carbonate and limestone and the like,
In order to reduce the flammability of plastics. However, this method is not very satisfactory method, more effective fire resistance tender
Add hydrated aluminum oxide or antimony and other inorganic flame retardants; containing material of phosphorus and Australia, both of these elements
Made of additives, can be attached to the main chain or a side chain of the polymer, which may be made of transparent, Paul
Held the original plastic characteristics of flame-retardant materials; intumescent fire retardant agent, also known as intumescent agent. These fire retardant case
To fire or heat the foam, the foam is very thick, it is difficult to burn, but also from the thermal and atmospheric insulation
Effect. Apparently use these methods to improve the content of fillers than simply cost, and some fire retardant
Corrosion of the mold. Add fire retardant in plastic is better to use plastic fire retardant coating economy.
