Description
Technical field
The present invention relates to heat conduction technical field, in particular it relates to a kind of Heat conduction nylon composite material and preparation method thereof.
Background technology
Traditional plastics are generally heat-insulating material, and the heat-conducting plastic of Coolpoly companies exploitation brings new contract for this field
Machine.The commercial applications of Coolpoly companies heat-conducting plastic manufactured about upper century-old ten thousand products product many in 1998
Individual field succeeds, and is widely used in various consumer electronics, power electronics, automobile, motorcycle, illumination, medical equipment and its
Its apparatus etc..Coolpoly heat-conducting plastics using engineering plastics and general-purpose plastics as base material, such as PP, ABS, PC, PA, LCP, PPS,
PEEK etc..Typical heat-conducting plastic pyroconductivity scope is 1-20W/mK, and some grades can reach 100W/mK. foldings one
Numerical value is about 5-100 times of conventional plastic, and general pyroconductivity only has 0.2W/mK.This conductivity is also golden with some
Symbolic animal of the birth year is worked as, and such as pyroconductivity of stainless steel is 15W/mK, and the pyroconductivity of some cast aluminium alloys is 50-100W/mK.
Compared with traditional material, heat-conducting plastic has higher flexible resistance and tensible rigidity, but impact strength is poor.Lead
Thermoplastic materials, which is primarily useful for substituting some, the micromodule, optical module, mechanical component of strict demand to product size
With the can ceramic objectses of medical component.When using elastomer as base material, it can be used as packing ring, damper or contact material.Lead
Thermoplastic materials is combined the simplification of plastic shaping with excellent heat conductivity, can be realized by injection moulding some metals or
