Abstract

The invention discloses a preparation method for an antistatic composite material. The preparation method comprises the following steps of uniformly mixing each component in parts by mass, adding the components into a twin-screw extruder for melting blending, and performing extrusion and cooling granulation to obtain the antistatic composite material. The prepared antistatic composite material has good antistatic performance and good wear resistance; influence on the mechanical strength of the antistatic composite material is eliminated; in addition, the antistatic composite material has high compatibility with resin, and transfer, precipitation and extraction in a plastic product are eliminated.

Description

A kind of preparation method of anti-static composite material
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of preparation method of anti-static composite material.
Technical background
Electrostatic, a kind of exactly electric charge remained static is immobilising electric charge (electric charge of flowing just defines electric current) in other words.When accumulation just defines electrostatic on certain object or time surperficial, and electric charge is divided into positive charge and negative charge two kinds, and that is electrostatic phenomenon is also divided into two kinds of i.e. positive electrostatic and negative electrostatic.Positive electrostatic is just defined when positive charge is gathered on certain object, negative electrostatic is just defined when negative charge is gathered on certain object, but no matter be positive electrostatic or negative electrostatic, all Charger transfer can occur when static electrification object contact zero potential object (ground connection object) or when having the object of potential difference with it, being exactly that we are daily sees Spark Discharges.Such as northern wintry weather is dry, and human body easily brings electrostatic, will Discharge Phenomena when contacting other people or metallic conductor, and these electrostatic have certain infringement to human body.Plastics are the widely used high molecular synthetic materials of modern society, have very high surface resistivity, thus make plastics electrostatic will be made to rest on frosting once friction, have impact on the use of plastics; And plastic prod is day by day universal, electrostatic is ubiquitous, very harmful to people.In order to prevent the electrostatic of plastics from producing, static inhibitor can be applied at frosting, but coating easily scraping, fundamentally can not solve electrostatic problem.There is the advantages such as light weight, not corrosion, good insulating, so plastics will be used in a lot of links of household electrical appliances production due to plastics.But the quality of much modified plastics is on the market unstable, its wear resisting property is not good, or easily weares and teares, and reduces work-ing life.
Summary of the invention
For above shortcomings in prior art, the object of the invention is to provide a kind of preparation method of nonabradable anti-static composite material.
The object of the invention is to be achieved through the following technical solutions: a kind of preparation method of anti-static composite material, be made up of following weight parts component: 160-165 mass parts styrene-butadiene rubber(SBR), 30-35 mass parts neoprene latex, 10-14 mass parts polycarbonate resin, 10-15 mass parts toughner, 10-15 mass parts softening agent, 10-13 mass parts calcium sulfate, 6-10 mass parts dispersion agent, after 10-12 mass parts static inhibitor and 10-14 mass parts toughner fully mix, add in twin screw extruder and extrude after melt blending at 170-200 DEG C of temperature and under screw speed 80-90r/min condition, cooling granulation, obtain anti-static composite material of the present invention.
Described toughner is grafting maleic anhydride with ethylene propylene terpolymer.
Described dispersion agent is the one in polyethylene wax, oxidized polyethlene wax, polyamide wax.
Described softening agent is adipic acid monomethyl ester, monoethyl adipatee, sebacic acid monomethyl ester or ethyl glutarate.
Described static inhibitor is graphite or conductive carbon fibre.
The beneficial effect that the present invention has: the plastics that the present invention obtains have good antistatic and wear resisting property; And do not affect the physical strength of plastics; To get well with the consistency of resin simultaneously, not move in plastics, do not separate out, be not extracted.
