Description
Technical field
The present invention relates to a kind of polycarbonate composite material, particularly relate to a kind of PE modified poly-carbonic acid and be combined
Material.
Background technology
Merlon (Polycarbonate, PC) is the high molecular polymer in strand containing carbonate group,
Having good thermostability and mechanical performance, be one of five large-engineering plastics, the three of PC engineering plastics greatly should
It is glazing, auto industry and electronics, electrical equipment industry with field, secondly also has industrial machinery part, light
Office equipment, medical treatment and health care, thin film, leisure and protective equipment, the building materials etc. such as dish, packaging, computer.
Containing phenyl ring, ester bond in the linear molecule backbone structure of Merlon so that it is existing rigidity, also have simultaneously
Standby certain toughness, good resistance to elevated temperatures, but there is also melt viscosity height, poor processability simultaneously
Problem, PC generally, without sharp melting point, (230-320 DEG C) scope under normal process temperature
Interior melt viscosity is high, and the little and temperature sensitive property of the sensitivity of viscosity versus shear rate is big, additionally, there may be
The problems such as high temperature facile hydrolysis, therefore PC belongs to a kind of plastics more difficult to process.
