Abstract
The invention discloses an antistatic PVC plastic and a preparation method thereof. The antistatic PVC plastic is prepared from PVC, DOP, CPE, metal powder, barium stearate, octadecanamide, dibasic lead sulfate, furnace black, and PE wax. The preparation method comprises the steps of: putting the PVC, DOP, CPE into a high-speed mixing machine for mixing uniformly, adding the other ingredients, stirring for 15-20min at a speed controlled at 300 ~ 600r/min and a temperature of 150 ~ 200 DEG C, emptying and cooling; and then performing extrusion granulation. The antistatic PVC plastic of the invention has the advantages of excellent antistatic properties and tensile strength, and high temperature resistance.
Description
Technical field
The present invention relates to the plastic cement field, relate in particular to a kind of antistatic PVC plastics and preparation method thereof.
Background technology
Static, a kind of exactly electric charge that remains static is immobilising electric charge (mobile electric charge has just formed electric current) in other words.When accumulation on certain object or the surface time just formed static, and electric charge is divided into two kinds of positive charge and negative charges, that is to say that it is positive static and negative static that electrostatic phenomenon also is divided into two kinds.When accumulating on certain object, positive charge just formed positive static, when accumulating on certain object, negative charge just formed negative static, but no matter be positive static or negative static, all charge transfer can take place when static electrification object contact zero potential object (ground connection object) or when the object of potential difference is arranged with it, be exactly our daily spark discharge phenomenon of seeing.Northern wintry weather drying for example, human body is with static easily, electric discharge phenomena will occur when contact other people or metallic conductor, and these static have certain infringement to human body.Plastics are the widely used high molecular synthetic materials of modern society, have very high surface resistivity, thereby make plastics will make static rest on frosting once friction, have influenced the use of plastics; And plastic prod is universal day by day, and static is ubiquitous, and is very harmful to people.In order to prevent the generation of static electricity of plastics, can apply static inhibitor at frosting, but coating scrapes easily, can not fundamentally solve electrostatic problem.The invention provides a kind of plastics that have antistatic effect itself.
Summary of the invention
The invention provides a kind of anti-static plastic and preparation method thereof, have good antistatic effect.
The present invention is by the following technical solutions:
A kind of antistatic PVC plastics comprise the component of following weight part meter:

PE wax 0.5～1
As preferably, the granularity of furnace treated black is greater than 80 orders.
As preferably, metal powder is one or more in Ba, Cd, the Zn powder.
The preparation method of above-mentioned anti-static plastic may further comprise the steps: PVC, DOP, CPE dropped into high mixer, mixes, add remaining ingredient again, and control rotating speed 300～600r/min, 150～200 ℃ of temperature stir 15-20min, the blowing cooling; Extruding pelletization then.
As preferably, described PVC drops into and is dried to moisture at 60-70 ℃ before the high mixer is 0.07%.
As preferably, the described dry warm air drying that adopts.
Surface resistivity of the present invention can well prevent static up to 2 * 108 Ω, and tensile strength has the good mechanical performance about 50MPa, transmittance is nearly 90%, and turbidity is lower, less than 4%, the appearance property of product is good, and texturing temperature surpasses 200 ℃, is far longer than general plastics.
