Abstract

The invention discloses a heat-conducting antistatic plastic which is prepared from the following components in parts by mass: 120-125 parts of LDPE (low-density polyethylene), 20-25 parts of polyamide imide resin, 10-13 parts of silicon carbide, 10-15 parts of beryllium oxide, 10-15 parts of AIN, 10-13 parts of polyethylene wax, 10-14 parts of aluminum oxide, 10-13 parts of ethyl acetate and 10 parts of lactose. The plastic has favorable heat-conducting and antistatic functions, does not influence the mechanical strength, has favorable compatibility with resin, and can not migrate, precipitate or be extracted in a plastic product.

Description

A kind of heat conduction anti-static plastic

Technical field

The invention belongs to polymeric material field, be specifically related to a kind of heat conduction anti-static plastic.

Technical background

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 generation of static can bring many troubles, as static discharge, can endanger electronics, makes equipment produce various faults, reduction of service life.Along with the market expansion of electric equipment products, more and more higher to the demand of electrostatic-resistant heat conducting plastic, such as the shell of circuit board material, electrical isolation plate, mobile communication equipment.Yet general-purpose plastics on the market, its thermal conductivity is low, and working temperature is low, and filler hardness is high, large to equipment attrition, easily produces static.

Summary of the invention

For above shortcomings in prior art, the object of the invention is to provide a kind of heat conduction anti-static plastic.

The object of the invention is to be achieved through the following technical solutions: a kind of heat conduction anti-static plastic, is comprised of following weight parts component: 120-125 mass parts LDPE, 20-25 mass parts polyamide-imide resin, 10-13 mass parts silicon carbide, 10-15 mass parts beryllium oxide, 10-15 mass parts AIN, 10-13 mass parts polyethylene wax, 10-14 mass parts aluminium sesquioxide, 10-13 mass parts ethyl acetate and 10 mass parts lactose.

An anti-static plastic, is comprised of following weight parts component: 122 mass parts LDPE, 23 mass parts polyamide-imide resins, 12 mass parts silicon carbide, 12 mass parts beryllium oxide, 12 mass parts AIN, 11 mass parts polyethylene waxs, 11 mass parts aluminium sesquioxides, 11 mass parts ethyl acetate and 10 mass parts lactose.

An anti-static plastic, is comprised of following weight parts component: 123 mass parts LDPE, 21 mass parts polyamide-imide resins, 11 mass parts silicon carbide, 14 mass parts beryllium oxide, 14 mass parts AIN, 13 mass parts polyethylene waxs, 13 mass parts aluminium sesquioxides, 12 mass parts ethyl acetate and 10 mass parts lactose.

The beneficial effect that the present invention has: the plastics that the present invention makes have good heat conduction and anti-static function; And do not affect the physical strength of plastics; With the consistency of resin, to get well, in plastics, do not move, do not separate out, be not extracted simultaneously.
