Description

Polycarbonate material and preparation method and application thereof
Technical Field
The invention belongs to the technical field of engineering plastics. More particularly, it relates to a polycarbonate material and its preparation method and application.
Background
Polycarbonate (PC) is an engineering plastic with excellent performance, has high mechanical strength, good impact resistance, stable size, good heat resistance, excellent electrical insulation property and good comprehensive performance, and is widely applied to the fields of household appliances, digital products and the like. For the electronic and electrical industry, for example, heat generated by electronic devices such as electronic components and chips can be rapidly accumulated and increased, the devices can not work normally due to overhigh temperature, and the metal with good heat conduction performance is usually used as a heat dissipation shell, but the metal shell can bring about the problems of signal shielding and the like. In order to solve the problems, the heat-conducting plastic is produced at the same time, and compared with metal, the heat-conducting plastic has the characteristics of light weight, strong plasticity, easy processing and forming, chemical corrosion resistance and the like; meanwhile, the heat-conducting plastic has the advantages of color diversity and low comprehensive cost, can meet the design freedom degree to the maximum extent, and becomes a good alternative scheme.
At present, the heat-conducting performance of the material is improved by adopting a method of adding a heat-conducting filler to uniformly fill a polymer matrix material. Among the common thermally conductive fillers are thermally conductive oxides (e.g., Al)2O3、MgO、SiO2Etc.), thermally conductive nitrides (e.g., AlN, Si3N4、BN、SiC、B4C3Etc.), the higher the thermal conductivity, the better the thermal conductivity of the plastic. For example, chinese patent application CN111087778A discloses a heat conductive polycarbonate composition with improved flow properties, which is obtained by adding surface-treated oxides, sulfides, and nitrides of main group II, III, and IV elements to achieve the effect of heat conduction. However, the filler adopted by the method needs higher filling amount to achieve better heat-conducting property, and the realization of high heat-conducting rate has a bottleneck; secondly, the impact property, the processing property and the like of the plastic can be directly reduced due to large filling amount, so that the practical application is influenced; and isThe surface polarity of the heat-conducting filler is strong, and the heat-conducting filler is difficult to uniformly disperse in a polymer, so that the viscosity of the composite material is increased, the requirement on production fluidity is difficult to meet, the mechanical property of the composite material is greatly reduced, and the application of the composite material is greatly limited.
