AI Technical Summary

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

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a flame-retardant SEBS modified polycarbonate alloy material. Background technique [0002] SEBS is a 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 better than 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. It is often modified with a rubber...
