Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of heat conductive flame-retarding plastics.
Technical background
In recent years, the higher requirement that the fast development of electronic product proposes the performance of plastics.Wherein, the integrated level of electronic circuit is more and more higher, and the gathering of heat is also more and more.Gathering of heat causes device temperature to raise, and job stability reduces.Therefore, its material requirements is had to high thermal conductivity, so that heat conducts rapidly.Yet, yet the heat-conducting plastic using in electronic product is on the market because the base material adopting mostly is non-high-temperature resistant material, causes the thermal conductivity of its worth product not high.
Simultaneously in order to adapt to different Working environments and user demand, thus can be to the plastics property improved performance, and and the plastics only with single function are in the more and more fierce market of competition now, more and more out inferior position.So need to carry out modification to plastics, make it there is a more than specific character, thereby strengthen the competitive power in market.
The plastics of flame retardant type are nonflammable, and rate of flame propagation is little, and mass loss rate and heat release rate are lower, and have certain self-extinguishing.But the flame retardant plastics performance of using at present can not meet the demands, and adopts halogen flame more, combustion processes can be emitted hydrogen halide human body is caused to serious harm.So the selection of fire retardant in plastics, is a very complicated process, must consider above-mentioned every factor.Yet the quality of modified plastics is on the market unstable, flame retardant properties is not good.
Summary of the invention
For above shortcomings in prior art, the object of the invention is to provide a kind of heat conductive flame-retarding plastics.
The object of the invention is to be achieved through the following technical solutions: a kind of heat conductive flame-retarding plastics, are comprised of following weight parts component: 155-158 mass parts PP, 20-25 mass parts carbon fiber, 10-15 mass parts aluminium powder, 10-15 mass parts crystalline flake graphite, 10-15 mass parts nitro-cotton resin, 10-13 mass parts silicon carbide, 10-18 mass parts aluminium sesquioxide, 5-8 mass parts DOS, 10-12 mass parts methylbenzene glycol and 10-14 mass parts aniline.
Plastics, are comprised of following weight parts component: 156 mass parts PP, 23 mass parts carbon fibers, 14 mass parts aluminium powders, 12 mass parts crystalline flake graphites, 13 mass parts nitro-cotton resins, 11 mass parts silicon carbide, 16 mass parts aluminium sesquioxides, 6 mass parts DOS, 11 mass parts methylbenzene glycol and 13 mass parts aniline.
