Problems solved by technology

The flame retardant performance of polycarbonate reaches the V-2 level. Although it is superior to ordinary thermoplastic materials, it is still difficult to meet the requirements for flame retardant performance of polycarbonate materials in certain application fields, such as computer components, automobile parts, and building materials.
Moreover, the processing temperature of polycarbonate material is high, and the residual internal stress of the material is high, which is easy to cause the material to crack

Abstract

Belonging to the technical field of high polymer material preparation, the invention relates to a preparation method of a flame retardant SEBS (styrene-ethylene / butadiene-styrene) modified polycarbonate alloy material. The method consists of: first putting 160-180 parts of polycarbonate resin into a drying device and drying it at 106DEG C, then placing the polycarbonate resin with 27-34 parts of SEBS resin, 8-14 parts of a compatibilizer masterbatch, 21-28 parts of a flame retardant, 7-11 parts of a metal oxide, 0.3-0.7 part of an anti-aging agent, and 1.8-2.6 parts of a lubricating agent into a high-speed mixer to conduct mixing, then transferring the mixture into a twin-screw extruder to carry out melt extrusion, controlling the first zone of the twin-screw extruder at a temperature of 265DEG C, the second zone at 268DEG C, the third zone at 273DEG C, the fourth zone at 278DEG C, the fifth zone at 283DEG C, the sixth zone at 288DEG C, the seventh zone at 288DEG C and the eighth zone at 288DEG C, and subjecting the material from a die to trough cooling and pelletizing, thus obtaining the flame retardant SEBS modified polycarbonate alloy material, which, in addition to good processing performance and cracking resistance as well as excellent mechanical properties, and also has ideal flame retardance.

Description

technical field [0001] The invention belongs to the technical field of polymer material preparation, and in particular relates to a method for preparing a flame-retardant SEBS-modified polycarbonate alloy material. Background technique [0002] SEBS refers to the copolymer of "styrene-ethylene / butadiene-styrene". Polycarbonate has excellent comprehensive properties and is widely used in the fields of electronics, construction, packaging, medical equipment and transportation. The flame retardant performance of polycarbonate reaches the V-2 level. Although it is superior to ordinary thermoplastic materials, it is still difficult to meet the requirements for flame retardant performance of polycarbonate materials in certain application fields, such as computer components, automobile parts, and building materials. Moreover, the processing temperature of polycarbonate material is high, and the residual internal stress of the material is high, which is easy to cause the material to...
