Description

A kind of PS composite materials
Technical field
The invention belongs to technical field of polymer materials, particularly relates to a kind of PS composite materials.
Background technology
Polystyrene (PS) has light, nontoxic, odorless, and chemical stability is good, and electrical insulation capability is good, and at normal temperatures not Common solvent is dissolved in, the advantages that water imbibition is small.Although the comprehensive performance of PS is very excellent, in some specific application necks Domain, the physical property of PS, often do not reach certain requirement, and which greatly limits the application range of PS.
The content of the invention
The object of the present invention is to provide a kind of PS composite materials and preparation method thereof, to improve the physical of PS composite materials Energy.
The present invention is achieved by the following technical solutions：
A kind of PS composite materials, are made of the component of following parts by weight：
The TiO2The preparation method of-g-P (GMA-AN), comprises the following steps：
1) by TiO2, lauryl sodium sulfate, polyoxyethylene nonylphenol ether 10, deionized water be placed in ultrasonic disperse 6- in four-hole boiling flask 10h, adds the potassium peroxydisulfate of certain mass, 80-120 DEG C of reaction 4-6h, obtains mixed solution A；
2) glycidyl methacrylate, acrylonitrile are added into four-hole boiling flask, are mixed with mixed solution A, 120-160 DEG C of reaction 8-12h, obtains mixed solution B；
3) by mixed solution B filtration washings, white product is obtained, 80-100 DEG C of reaction 6-8h is up to product TiO2-g-P (GMA-AN)。
The TiO2, lauryl sodium sulfate, the polyoxyethylene nonylphenol ether 10, the deionized water and the potassium peroxydisulfate Mass ratio be 20-30: 0.1-0.3: 0.2-0.4: 200-280: 1-3.
The mass ratio of the glycidyl methacrylate, the acrylonitrile and the mixed solution A is 12-16: 10-14 ∶230-260。
The graphene is the graphene after processing, and the processing method of the graphene after the processing comprises the following steps：
1) weigh octadecylamine, ethanol is added into the aqueous solution of graphene, under 100-120 DEG C of oil bath pan environment, return Stream reaction 20-24h；
2) step 1) products therefrom is filtered, is placed in 60-80 DEG C of vacuum tank dry 20-24h, the stone after must both handling Black alkene.
The mass ratio of the octadecylamine, the ethanol and the graphene is 20-28: 50-60: 100-160.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyls) Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one kind or more in 6- (3,5- di-t-butyl -4- hydroxyphenylmethyls) benzene Kind.
The lubricant is the one or more in zinc stearate, calcium stearate or potassium stearate.
The beneficial effects of the invention are as follows：
The technical program utilizes the oxygen-containing functional group on the surface of graphene, in surface grafting by way of chemical bonding Suitable long chain alkane, long chain alkane can effectively stop the reunion of graphene, allow graphene to be better dispersed in PS and answer In condensation material.The addition of graphene can lift the antistatic property in PS composite materials at the same time.
The technical program is in TiO2GMA, AN are grafted on surface, compared to directly adding TiO2, physical property is more preferable, this is Because one side P (GMA-AN) is connected to TiO with chemical bond2, surface grafting rate higher, is conducive to stress to be transmitted to particle On, another aspect surface grafting thing can improve TiO2With PS compatibilities.
