Connect, the chain macromolecule compound that repeated arrangement is formed, abbreviation PC.Makrolon has good rigidity, toughness, low temperature resistant
Property, heat resistance, glossiness, transparency and electrical insulating property etc., but its melt viscosity is big, chemical proofing is poor, be also easy to produce stress
Ftracture and to notch sensitive etc..
The fire retardant of traditional fire-retardant polycarbonate is halogenated flame retardant, although its anti-flammability is very well and addition is few,
But it can produce substantial amounts of toxic smog and carcinogenic bioxin during fire-retardant, and the halocarbon for producing can corrode
Equipment, causes secondary pollution.
As people are to environmental protection and the attention of personal safety, the country such as European Union has limited halogenated flame retardant
Use.At present, the conventional flame retardant thermoplastic resin composition of in the market is mainly phosphoric acid ester, Sulfonates and polysiloxane-based
