A flame retardant glass fiber polycarbonate alloy

Abstract

The invention discloses a flame-retardant glass fiber polycarbonate alloy. The invention specially designs a flame retardant to be added to the glass fiber polycarbonate composite material, which contains an appropriate amount of calcium nitrate, hexanediol, and iron citrate. It can effectively improve the flame retardant performance of the product, and the composite material will not burn or drip under high temperature, and effectively eliminate the "wick effect" of glass fiber. Due to its excellent mechanical properties and flame-retardant properties, the glass fiber polycarbonate composite material provided by the invention is especially suitable for preparing auto parts, electronic product components and the like.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a flame-retardant glass fiber polycarbonate alloy. Background technique [0002] Glass fiber reinforced polycarbonate material has high strength, high impact resistance, and good dimensional stability. It is a "strong and tough" material. After adding glass fiber reinforcement, polycarbonate greatly improves its mechanical properties and heat resistance. and dimensional stability. In practical applications, plastic can replace steel and reinforced engineering plastics to meet the requirements of light weapon packaging boxes, automotive fields, home appliances and other fields. Existing polycarbonate polymers usually have poor flame retardancy and low safety, which limits their applications in many fields; for example, in lighting equipment / automotive construction, polycarbonate polymers must meet very stringent fire protection requirements For this reason, the flame...

Problems solved by technology

Existing polycarbonate and glass fiber products all add bromine, chlorine and other halogen flame retardants to their raw materials in order to achieve a better flame retardant effect. Although the flame retardant effect is excellent, it will produce large smoke and strong toxicity when burned Hydrogen halide and other halogen-containing organic substances, and dioxins will be produced when burned, which is extremely harmful to the human body

As we all know, halogen-based flame retardant materials will produce a large amount of toxic and corrosive smoke when burned, which will pollute and corrode the environment and molds, and have been banned in many developed countries; most halogen-free flame-retardant Although the effect of the drug is good, it is difficult to promote its use in China due to the high cost

In addition, these flame retardants have no substantial mitigation effect on the "wicking effect" of glass fiber, and are not resistant to high temperature, and are easy to decompose and fail at high temperature, which cannot fundamentally solve the fire performance of glass fiber polycarbonate composite materials. bad question
