Problems solved by technology

But PC also has its disadvantages: prone to stress cracking, poor wear resistance, poor processing fluidity, high cost, and poor solvent resistance
The flame retardants that have been studied so far mainly include bromine-based, phosphorus-based and silicon-based flame retardants. However, bromine-based flame retardants release toxic gases such as HCl during combustion, which pollute the environment and are restricted in use. They are gradually being replaced by halogen-free flame retardants. Fuel replacement

Abstract

The invention discloses a halogen-free flame retardant PC / PET alloy material and a preparation method thereof. The halogen-free flame retardant PC / PET alloy material comprises, by mass, 10-40% of PC, 50-70% of PET, 5-12% of a compound halogen-free flame retardant master batch, 3-8% of a compatibilizer, 0.5-2% of a dispersant and 0.1-1% of an antioxidant. The halogen-free flame retardant PC / PET alloy material simultaneously has the respective advantages of the PC and the PET, has the high strength and heat resistance of the PC, has the chemical resistance and easy machinability of the PET, and also has excellent comprehensive properties; and the compound halogen-free flame retardant master batch has the characteristics of no halogen, flame retardation, smoke inhibition, non-toxicity, safety, high efficiency, less consumption, use convenience and the like when the compound halogen-free flame retardant master batch is used in the flame retardation modification of the halogen-free flame retardant PC / PET alloy material.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant PC / PET alloy material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is one of the five major engineering plastics. It has comprehensive and balanced mechanical, electrical and heat resistance properties, and is famous for its excellent impact strength and creep resistance. But PC also has its disadvantages: prone to stress cracking, poor wear resistance, poor processing fluidity, high cost, and poor solvent resistance. Polyethylene terephthalate (PET) is a crystalline polymer that can maintain excellent physical and mechanical properties in a wide temperature range. It has excellent fatigue resistance, friction resistance, and aging resistance. Excellent performance, outstanding electrical insulation, stable to most organic solvents and inorganic acids, low energy consumption and good processability. ...
