Reinforced and toughened flame-retardant PC (Poly Carbonate)/ABS (Acrylonitrile Butadiene Styrene) composite material and preparation method thereof

Abstract

The invention discloses a reinforced and toughened flame-retardant PC (Poly Carbonate) / ABS (Acrylonitrile Butadiene Styrene) composite material and a preparation method thereof. The reinforced and toughened flame-retardant PC / ABS composite material comprises the following components in parts by weight: 10-70 parts of PC, 5-60 parts of ABS, 1-8 parts of organic montmorillonite, 1-3 parts of compatilizer, 0.5-2 parts of antioxidant and 0.1-3 parts of flame retardant. The PC / ABS composite material is modified by adding organic montmorillonite and inorganic non-halogen fire retardants into the PC / ABS composite material; and as the organic montmorillonite has a laminated structure, the organic montmorillonite can be uniformly dispersed into the composite material, the toughness of the composite material can be improved, and the rigidity of the composite material can be improved as well. Since the inorganic non-halogen fire retardant is adopted, the flame-retardant property of the composite material is improved, and the composite material is green and environment-friendly, so that the prepared composite material has a broad application prospect.

[0002] PC (polycarbonate) has excellent impact resistance, creep resistance, dimensional stability and electrical insulation. It is an engineering plastic with superior performance. It is widely used in mechanical equipment, construction, transportation and other fields, but there are also The disadvantages of poor fluidity, easy stress cracking, easy aging and poor wear resistance limit its application in many fields

[0003] ABS is a thermoplastic resin with good chemical resistance, good molding processability and high cost performance. The disadvantages are poor heat resistance and weather resistance, low impact strength and tensile strength.

The combination of the two can combine the excellent properties of the two, but the compatibility of PC and ABS is not good. Although a compatibilizer can be added, there is still a problem of poor compatibility, which in turn affects the rigidity and toughness of the composite material.

Although halogenated flame retardants have good flame retardancy, they will produce a large amount of toxic gases when burned, which will pollute the environment and endanger human health.
