Description
Technical field
The invention belongs to technical field of polymer materials, particularly relate to a kind of antistatic PS composite material.
Background technique
For polystyrene (PS) as common thermoplastic, application is very extensive.But with the development of science and technology, one
A little specific fields, people are more next to the performance requirement of PS material, especially wearability, antistatic property and mechanical property requirements
Higher, which greatly limits application of the PS composite material on these special dimensions.
With butyl polyacrylate (PBA) engrafted nanometer zirconium dioxide (ZrO2), then PS is modified, so that it is multiple to improve PS
Wearability, antistatic property and the physical property of condensation material, this method not yet see report so far.
Summary of the invention
The object of the present invention is to provide a kind of antistatic PS composite material, with improve the wearability of PS composite material, resist it is quiet
Electrical property and physical property.
The present invention is achieved by the following technical solutions:
A kind of antistatic PS composite material, is made of the components of following parts:
The modified Nano ZrO2, preparation method is as follows:
(1) a certain amount of butyl acrylate, nanometer ZrO are weighed2, potassium peroxydisulfate, aluminum sulfate and neopelex；
(2) by potassium peroxydisulfate, neopelex, butyl acrylate and nanometer ZrO2After mixing, at 160-180 DEG C
Oil bath react 6-12h, then add aluminum sulfate demulsification 6-10h, filtration washing both modified Nano ZrO2。
The nanometer ZrO2Diameter is 40-80nm.
The butyl acrylate, the nanometer ZrO2, the potassium peroxydisulfate, the aluminum sulfate and the detergent alkylate sulphur
The mass ratio of sour sodium is 10-30: 30-40: 0.3-0.7: 1-3: 0.1-0.3.
The antistatic agent is antistatic agent Atmer 163 or antistatic agent Atmer 190.
The compatilizer is MAH-SEBS.
Three (2,4- di-t-butyl) phenyl-phosphites that the antioxidant is, four [β-(3,5- di-t-butyl -4- hydroxy benzenes
Base) propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one of 6- (3,5- di-t-butyl -4- hydroxyphenylmethyl) benzene
Or several mixing.
The lubricant is one of zinc stearate, calcium stearate or potassium stearate or a variety of.
The preparation method of anti-static and abrasion-resistant high-performance PS composite material described in any of the above embodiments, comprising the following steps:
(1) 60 parts -80 parts of PS, 5 parts -10 parts of phenolic resin, 20 parts of -30 parts of modified Nano ZrO are weighed2, 0.1 part-
0.5 part of MAH-SEBS, 0.1 part of -0.5 part of antioxidant, 0.1 part of -0.3 part of mix lubricant simultaneously stir evenly, and obtain mixture；
(2) by mixture extruding pelletization obtained in step (1) to get arrive PS composite material.
Preferably, the step (2) specifically: mixture obtained in step (1) is put into double screw extruder
Extruding pelletization in hopper, wherein the double screw extruder includes six humidity provinces sequentially arranged, area's temperature 140~180
DEG C, two 190~230 DEG C of area's temperature, three 190~230 DEG C of area's temperature, four 190~230 DEG C of area's temperature, five area's temperature 190~230
DEG C, six 190~230 DEG C of area's temperature, 190~230 DEG C of head temperature, 200~280r/min of screw speed.
The beneficial effects of the present invention are:
The presence of MAH-SEBS enhances PS and nanometer ZrO in the technical program2Interfacial adhesion, nanometer ZrO2In PS base
Favorable dispersibility in body, this is more advantageous to the heterogeneous nucleation for promoting PS matrix, accelerates the crystalline rate of PS matrix, enhances PS
The mechanical property of composite material.
The addition of antistatic agent makes the antistatic property of PS composite material be greatly improved, surface resistivity drop
To 108Ω or so.
