Problems solved by technology

The flame retardant BDP is liquid at room temperature. In a high-temperature processing environment, the viscosity of BDP is too different from that of PC / ABS melt, which leads to the inability to disperse stably and uniformly in the barrel and screw of the extruder, and the dispersion state of BDP is inconsistent, resulting in The flame retardancy and mechanical properties of the material are affected, and in the subsequent processing and molding process, BDP is easy to precipitate from the PC / ABS material

Abstract

A disclosed high-toughness low-precipitation halogen-free flame-retardant PC / ABS material is prepared from the following raw materials in parts by mass: 40 to 80 parts of polycarbonate, 5 to 20 partsof acrylonitrile-butadiene-styrene copolymer, 5 to 30 parts of modified BDP flame retardant, 2 to 20 parts of toughening agent, 0.2 to 1 part of antioxidant, 0.3 to 1 part of internal lubricant, 0.3 to 1 part of external lubricant, 0.3 to 1 part of anti-dripping agent and 0 to 1 part of pigment. The invention also discloses a preparation method of the high-toughness low-precipitation halogen-freeflame-retardant PC / ABS material. According to the invention, the flame-retardant and impact-resistant stability of the PC / ABS material can be effectively improved, and the problem that a flame retardant is separated out in the subsequent molding process can be improved.

Description

technical field [0001] The invention relates to the technical field of polycarbonate materials, in particular to a high-toughness, low-precipitation, halogen-free flame-retardant PC / ABS material and a preparation method thereof. Background technique [0002] PC / ABS material refers to a mixture of polycarbonate and acrylonitrile-butadiene-styrene copolymer, a thermoplastic made of polycarbonate (PC) and polyacrylonitrile (ABS), combining two The excellent characteristics of the material, the formability of the ABS material and the mechanical properties, impact strength, temperature resistance, and ultraviolet (UV) resistance of the PC can be widely used in automotive interior parts, business machines, communication equipment, home appliances and lighting equipment. . [0003] Since most electrical materials have flame retardant requirements, combined with the current international trend of halogen-free flame-retardant materials, higher requirements are put forward for the ha...
