Embodiment 1

[0018] 1) Production of flame retardant masterbatch

[0019] Pour 30kg of CBT resin, 69kg of solid polycondensation type phosphate flame retardant, 0.2kg of phenolic antioxidant and 0.8kg of phosphite or thioester antioxidant into a high-speed mixer, and mix for 60 seconds at a low speed. The mixed raw materials are fed into a twin-screw extruder for forced feeding, blending and extruding. The blending processing temperature is 180-200°C, the screw speed is 250-350r / min, the product is thermally cut into pellets, air-dried and cooled, and packed for later use. CBT resin has a macrocyclic oligoester structure and is a mixture of different low molecular weight cyclic oligomers. The unique composition and low melt viscosity make it an ideal base resin for concentrated masterbatches, and can be mixed with amorphous, semi-crystalline and crystalline Compatible with permanent resins and improves fluidity. Solid polycondensation type phosphate flame retardant has good flame retarda...

Abstract

The invention relates to the field of organic polymer, in particular to a solid polycondensation type phosphate ester inflaming retarding ABS / PC (Acrylonitrile Butadiene Styrene / Polycarbonate) alloy and a preparation method thereof. CBT resin, a solid phosphate ester inflaming retarding agent, a phenols antioxygen and a phosphite ester or thioester antioxygen are mixed to prepare an inflaming retarding parent stock; polycarbonate, acrylonitrile-butadiene-styrene copolymer, acrylonitrile-EPDM (Ethylene-Propylene-Diene Monomer)-styrol copolymer and the inflaming retarding parent stock are poured into a high-speed mixer, and a toughening compatilizer, polytetrafluoroethylene and a lubricating agent are added to be stirred, wherein the raw materials comprise the following components in percent by weight: 19-30 percent of the CBT resin, 69-80 percent of the solid phosphate inflaming retarding agent, 0.1-0.5 percent of the phenols antioxygen and 0.1-1 percent of the phosphite ester or thioester antioxygen; and the solid polycondensation type phosphate ester inflaming retarding ABS / PC alloy material comprises the following components in percent by weight: 35-50 percent of the acrylonitrile-butadiene-styrene copolymer, 8-15 percent of the polycarbonate, 30-40 percent of the inflaming retarding parent stock, 8-15 percent of the acrylonitrile-EPDM-styrol copolymer, 1-5 percent of the toughening compatilizer, 0.2-1 percent of the polytetrafluoroethylene and 0.2-0.6 percent of the lubricating agent.

Description

technical field [0001] The invention relates to the field of organic polymer materials, in particular to a solid polycondensation type phosphate flame-retardant ABS / PC alloy and a preparation method thereof. Background technique [0002] We know that flame-retardant acrylonitrile-butadiene-styrene copolymer (ABS) / polycarbonate (PC) alloy is an important engineering plastic alloy, which has better performance than pure PC and ABS resin. The halogen-free flame retardant ABS / PC alloy has good formability and low temperature impact resistance, good heat distortion temperature, light stability and good flame retardancy. Compared with PC, it reduces the melt viscosity, improves the processing performance, and greatly improves the stress cracking resistance of the product; compared with ABS, it improves the heat resistance and weather resistance, and the cost is between PC and ABS. It also has the advantages of both, and can be better used in industries such as automobiles, electr...
