Embodiment 1

[0015] Weigh 100 kg of polycarbonate, 60 kg of ABS resin, 20 kg of flame retardant, 5 kg of chlorinated polyethylene, 4 kg of EVA and 1 kg of oleic acid, wherein the flame retardant is more than 8 kg Polyaryl phosphate, 3 kg of magnesium hydroxide, 2 kg of barium hydroxide and 7 kg of potassium fluorobutane sulfonate.

[0016] Put PC pellets and ABS pellets in a vacuum drying oven, dry PC pellets at 115°C for 5 hours to obtain dry PC pellets; dry ABS pellets at 80°C for 3 hours to obtain dry ABS pellets . After mixing dry PC pellets and ABS pellets, add flame retardant, chlorinated polyethylene, EVA and oleic acid, mix evenly, place in a twin-screw screw machine, and pelletize after melt extrusion to obtain PC / ABS alloy pellets. The temperature of each zone of the twin-screw screw machine is: zone 1 temperature: 220°C, zone 2 temperature: 230°C, zone 2 temperature: 230°C, zone 4 temperature: 235°C, zone 5 temperature: 230°C, zone 6 temperature: 230 ℃; twin-screw residence t...

Abstract

The invention relates to a flame-retardant PC / ABS (Poly Carbonate / Acrylonitrile-Butadiene-Styrene) alloy containing no halogen-system flame retardant. The flame-retardant PC / ABS alloy comprises 80-150 parts of polycarbonate, 40-70 parts of ABS resin, 12-30 parts of flame retardant, 1-10 parts of compatilizer, 1-10 parts of toughening agent and 1-5 parts of lubricant. The flame-retardant PC / ABS alloy has the advantages of low production cost, good machining performance, high flame-retardant grade and environmental friendliness.

Description

technical field [0001] The invention relates to the field of macromolecules, in particular to a flame-retardant PC / ABS alloy without halogen-based flame retardants. Background technique [0002] Polycarbonate (PC) is an engineering plastic with excellent performance, but it has disadvantages such as poor processing fluidity, easy stress cracking, sensitivity to notch, easy wear, poor chemical resistance, and high price, which make its application in many fields restricted. limit. The performance of acrylonitrile-butadiene-styrene (ABS) is between engineering plastics and general-purpose plastics. In order to meet the fire safety requirements of PC / ABS alloys in practical applications, the research on halogen-free and environment-friendly PC / ABS alloy materials has become the focus in the field of flame retardancy. Contents of the invention [0003] The object of the present invention is to provide a flame-retardant PC / ABS alloy without halogen-based flame retardants. ...
