Abstract
The invention provides a flame retardant acrylonitrile-butadiene-styrene (ABS)/polycarbonate (PC) alloy special material. The special material is characterized in that an advanced production technology is adopted to combine ABS, polycarbonate, a compatibilizer, a flexibilizer, a flame retardant and the like together and prepare the flame retardant ABS/PC alloy material. The flame retardant ABS/PC alloy material provided by the invention has excellent comprehensive performance; and the products of the material have good mechanical properties, heat resistance, impact resistance and fire resistance, and the flame retardancy reaches the grade UL94V-0. The products have good injection moulding property and beautiful appearance, and can be used in large and small parts such as communication equipment parts, computer parts, office equipment parts, automobile parts, electronic/electrical parts and industrial parts. The flame retardant ABS/PC alloy special material can be applied in some fields to replace PC and used in fields with harsh working environment to replace ABS.
Description
Technical field the present invention relates to the polymer modification technology, especially makes the new technology of flame-proof ABS/PC alloy PP Pipe Compound.
The background technology ABS resin is a kind of widely used thermoplastic engineering plastic, and any surface finish has good processing properties and shock resistance, moderate cost, and over-all properties is good.But ABS resin is inflammable, does not have flame retardant resistance, usually causes fire failure, brings life and property loss to people, thereby has limited its application in some fields.
The PC resin is a kind of widely used engineering plastics, has many-sided excellent properties, like electrical insulating property, dimensional stability, the thermotolerance of excellence, also have from put out, performance such as fire-retardant, but price is expensive.ABS resin and PC consistency are relatively poor, for improving consistency, can in system, add solubilizing agent.PC and ABS that employing has flame retardant resistance carry out blend, and the over-all properties of the ABS/PC alloy material of generation is better, has good mechanics, heatproof, impact property and flame retardant resistance especially, and its flame retardant resistance reaches the UL94V-0 level.Processing characteristics is good, also has good stress crack resistance performance.
Summary of the invention the present invention provides a kind of flame-proof ABS/PC alloy PP Pipe Compound, and it is by ABS; Polycarbonate, i.e. PC; Expanding material; Toughner; Compositions such as fire retardant.Before moulding, at first to carry out drying to pellet, drying conditions is at 120 ℃ of oven dry 4-6h.The ABS that measures, PC and other auxiliary agents are put into high-speed mixer, and first stirring at low speed a moment, a little time of high-speed stirring again is to evenly.Flame-proof ABS/PC alloy material is prepared in melt blending granulation on twin screw extruder.
