Description
Technical field
The present invention relates to a kind of alloy plastic and preparation method thereof, particularly relate to a kind of antistatic PC/ASA alloy plastic and preparation method thereof.
Background technology
Merlon (PC)/acrylonitrile one styrene one acrylic copolymer (ASA) belongs to polycarbonate alloy class, there is the weatherability of excellent shock resistance, heat resistance and excellence, being widely used in the aspect such as automobile, electronic product, prospect is considerable.But plastic products easily produce electrostatic and glue and inhale dust, can cause major disaster time serious.Generally, the method preventing polymer surfaces from producing electrostatic has air ionization, metal contact discharge, conductive materials imports, surface forms hygroscopic mem-brane and applies antistatic additive etc..
But, the antistatic effect of usual PC/ASA alloy plastic is unsatisfactory.
Summary of the invention
For above-mentioned deficiency present in prior art, one of the technical problem to be solved provides a kind of antistatic PC/ASA alloy plastic.
The preparation method of the two offer above-mentioned antistatic PC/ASA alloy plastics of the technical problem to be solved.
The technical problem to be solved is achieved by the following technical solution:
A kind of antistatic PC/ASA alloy plastic, is made up of following weight parts raw material:
Described compatilizer is PE-g-ST, PP-g-ST, ABS-g-MAH, PE-g-MAH or PP-g-MAH.
Described antistatic additive is the one in (3-dodecanamide propyl) trimethyl sulfate methyl ammonium, lauric acid diethyl amide and N, N-bis-(2-ethoxy)-myristamide or its mixture.
Preferably, described antistatic additive is 50-70wt% (3-dodecanamide propyl) trimethyl sulfate methyl ammonium, 10-30wt% lauric acid diethyl amide and 10-30wt%N, N-bis-(2-ethoxy)-myristamide composition.
Wherein, (3-dodecanamide propyl) trimethyl sulfate methyl ammonium, also known as antistatic additive LS, English name: (3-lauramidopropyl) trimethyl ammonium methyl sulfate.Lauric acid diethyl amide, No. CAS: 120-40-1.N, N-bis-(2-ethoxy)-myristamide, No. CAS: 7545-23-5.
Present invention also offers the preparation method of above-mentioned antistatic PC/ASA alloy plastic: weigh each component by proportioning, after mixing, melting mixing, extruding pelletization, i.e. obtain described antistatic PC/ASA alloy plastic.
Concrete, can be to weigh each component by proportioning, in high-speed mixer, under room temperature, control rotating speed is at 300-400 rev/min, mixes 2-8 minute, through double screw extruder extruding pelletization at a temperature of 230-270 DEG C, i.e. obtains described antistatic PC/ASA alloy plastic.
The antistatic behaviour of the antistatic PC of the present invention/ASA alloy plastic is more excellent, and surface is difficult to adsorb dust, and the combination property of product is more excellent, can become variously-shaped automotive upholstery by injection molding.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
In following embodiment, each raw material introduction:
The injection grade PC resin of Japan Di Ren company trade mark L-1250Y selected by PC resin.
ASA resin, selects the ASA resin of BASF Aktiengesellschaft trade mark KR2866C.

Compatilizer, selects compatilizer PE-g-MAH.
Antioxidant 1076 selected by antioxidant.
Antistatic additive: (3-dodecanamide propyl) trimethyl sulfate methyl ammonium, also known as antistatic additive LS, English name: (3-lauramidopropyl) trimethyl ammonium methyl sulfate.
Lauric acid diethyl amide, No. CAS: 120-40-1.
N, N-bis-(2-ethoxy)-myristamide, No. CAS: 7545-23-5.
Embodiment 1-4
Each raw material is weighed according to embodiment 1-4 data corresponding in table 1.
In high-speed mixer, under room temperature, control high-speed mixer rotating speed is at 350 revs/min, mixes 7 minutes, proceed to after taking-up in double screw extruder, extruding pelletization at a temperature of 250 DEG C, screw machine rotating speed controls, at 400 revs/min, i.e. to obtain described antistatic PC/ASA alloy plastic.
