Embodiment 1

[0031] A low-gloss, high-strength, halogen-free flame-retardant PC / ASA blend material, including the following weight ratio raw materials:

[0032] PC: 80 parts, ASA: 10 parts, halogen-free flame retardant: 20 parts, toughening agent: 10 parts, low gloss agent: 1 part, compatibilizer: 1 part, anti-dripping agent: 0.1 part, antioxidant Agent: 1.8 parts, UV absorber: 0.2 parts, lubricant: 0.2 parts.

[0033] Further, the PC is a mixture of different bisphenol A polycarbonates. By mixing different bisphenol A polycarbonates, a polycarbonate mixture with better comprehensive performance is obtained, so that it not only has higher mechanical properties and Thermodynamic properties, but also its high fluidity, good processing performance.

[0034] Further, the halogen-free flame retardant includes one or more of organosiloxane flame retardants, inorganic hydroxide flame retardants, sulfonate flame retardants, phosphorus flame retardants, nitrogen flame retardants kind.

Description

technical field [0001] The invention relates to the field of plastic blending, in particular to a low-gloss, high-strength, halogen-free flame-retardant PC / ASA blend material and a preparation method thereof. Background technique [0002] PC / ASA, a mixture of polycarbonate and styrene-acrylonitrile-acrylic rubber copolymer, is a composite material synthesized by PC and ASA, which combines the mechanical properties, high temperature resistance, impact resistance of PC and the easy molding of ASA , weather resistance and chemical resistance, widely used in automotive exterior parts, home appliances and lighting equipment. [0003] The flame-retardant PC / ASA materials currently used in the market are mainly divided into halogen-free flame-retardant PC / ASA and halogen-free flame-retardant PC / ASA. Due to the increasing awareness of environmental protection, halogen-free flame-retardant PC / ASA composite materials Has been favored by the market. However, on the one hand, the glos...
