Problems solved by technology

[0005] Halogen-containing flame-retardant materials have excellent flame-retardant properties, but such halogen-containing flame-retardant materials will produce a large amount of smoke and toxic corrosive hydrogen halide gas, causing secondary hazards, so halogen-free flame retardants came into being. It is gradually replacing the use of halogen-containing flame retardants in flame-retardant materials, but compared with halogen-containing flame retardants, the flame-retardant performance of most halogen-free flame retardants is difficult to meet the flame-retardant requirements of thin-walled parts

Abstract

The invention discloses a high-toughness halogen-free flame-retardant PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) alloy reflecting material which comprises the following components in percentage by weight: 50-70% of PC resin, 5-10% of ABS resin, 2-3% of self-made compatilizer, 10-30% of titanium white, 0.2-0.5% of halogen-free flame retardant 1, 0.2-1% of halogen-free flame retardant 2, 0.2-0.3% of anti-dripping agent, 0.2-0.5% of antioxidant and 0.4-0.8% of processing assistant. The preparation method comprises the following steps: weighing the components in percentage by weight, mixing in a high-speed mixer for 2-3 minutes, discharging, and carrying out extrusion granulation on a double screw extruder, wherein the processing temperature is 220-260 DEG C, and the rotation speed of the screw is 380-420 rpm. The method improves the processibility, stress cracking resistance and solvent resistance of the PC. The two halogen-free flame retardant are compounded, so that the reflecting material can be more widely applied to manufacturing of reflecting cups and various other illumination reflecting products, and reflecting panels.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PC / ABS polymer alloy, in particular to a high-toughness halogen-free flame-retardant PC / ABS alloy reflective material and its preparation method and application. Background technique [0002] Polycarbonate (PC) is an engineering plastic with superior comprehensive properties. It has excellent impact toughness, dimensional stability, electrical insulation, creep resistance, weather resistance, transparency and non-toxicity. It is widely used in Automotive, electrical and electronic, construction, office equipment, packaging, sports equipment, medical care and other fields, but pure PC also has the disadvantages of notch sensitivity and poor stress crack resistance. At the same time, due to the high transparency of PC, the reflectivity of light is very Low, generally less than 5%, can not meet the requirements of reflective lampshades or reflectors, [0003] Titanium d...
