Description
Technical field
The invention belongs to technical field of polymer materials, particularly relate to a kind of high performance PE composite material.
Background technique
For polyethylene (PE) as common thermoplastic, application is very extensive.But with the development of science and technology, it is one
A little physical property requirements are high, cannot meet the requirements in the high application field of dielectric properties, which greatly limits PE composite materials to exist
Application on these special dimensions.
Summary of the invention
The object of the present invention is to provide a kind of high performance PE composite materials, to improve mechanical property and the Jie of PE composite material
Electric constant.
The present invention is achieved by the following technical solutions:
A kind of high performance PE composite material, is made of the component of following parts by weight:
The preparation method of the PE-g-PS, comprising the following steps:
(1) weigh a certain amount of PE, benzoyl peroxide, calcium hydroxy phosphate, neopelex, polystyrene and
Water；
(2) after mixing the weighed article of institute, 6-8h is reacted in 100-120 DEG C of oil bath；
(3) it is filtered by vacuum after reaction using vacuum pump, the vacuum oven that suction filtration is placed on 60-80 DEG C is dry
2-4h both obtains product PE-g-PS.
The PE, the benzoyl peroxide, the calcium hydroxy phosphate, the neopelex and polystyrene
Mass ratio be 60-80: 2-4: 1-3: 2-6: 20-40.
The PS-TiO2Preparation method, comprising the following steps:
(1) a certain amount of PS, nano-TiO are weighed2, potassium peroxydisulfate, NaCl and neopelex；
(2) by KPS, neopelex, PS and nano-TiO2After mixing, 8- is reacted in 140-180 DEG C of oil bath
12h, then adds NaCl demulsification 7-13h, and filtration washing both obtains PS-TiO2。
The nano-TiO2Diameter is 30-70nm.
The PS, the nano-TiO2, the potassium peroxydisulfate, the NaCl and the neopelex quality
Than being 70-90: 15-25: 2-4: 5-9: 1-3.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyl)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one of 6- (3,5- di-t-butyl -4- hydroxyphenylmethyl) benzene or several
The mixing of kind.
The lubricant is one of zinc stearate, calcium stearate or potassium stearate or a variety of.
A kind of preparation method of the high performance PE composite material of any of the above-described, comprising the following steps:
(1) 60 parts -80 parts of PE, 10 parts -20 parts of PS, 20 parts of -30 parts of PE-g-PS, 4 parts of -8 parts of PS-TiO are weighed2、
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 PE 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 180~220 DEG C of area's temperature, three 180~220 DEG C of area's temperature, four 180~220 DEG C of area's temperature, five area's temperature 180~220
DEG C, six 180~220 DEG C of area's temperature, 180~220 DEG C of head temperature, 200~280r/min of screw speed.
The beneficial effects of the present invention are:
The new PE composite material not only excellent physical properties of synthesis, dielectric constant is also high, improves answering for PE composite material
Use range.
