Description
Technical field
The invention belongs to technical field of composite materials more particularly to a kind of preparation methods of shock resistance PS modified material.
Background technique
PS resin (PS) is the polymer by styrene monomer free radical addition polymerization, for it is a kind of it is nontoxic, odorless,
Colorless and transparent thermoplastic resin, usually amorphous random polyme.PS material has excellent physico-chemical property, vitrifying
80-90 DEG C of temperature, amorphous density of states 1.04-1.06g/cm3, crystalline density 1.11-1.12g/cm3,240 DEG C of melting temperature, electricity
Resistance rate is 1020-1022 Ω cm, thermal coefficient 0.116W/ (mK) at 30 DEG C, has excellent insulation, insulation and transparent
Property, it 0-70 DEG C of long-term use temperature, since its is cheap and easy processing forms, is widely applied.
But existing simultaneously property of PS material is crisp, impact strength is low, the shortcomings that stress cracking and poor heat resistance easily occurs, greatly
The application field of PS material is limited greatly.In the prior art, the method for solving PS material disadvantage is mainly that PS resin and rubber are total
Mixed modification, obtains the PS composite material of high impact resistance and high tenacity, but relies solely on rubber and greatly reduce PS material
Rigidity, while PS material bring environmental issue is exacerbated, so that the PS resin material for being difficult to degrade originally is more difficult to via life
Object decomposes or photodegradation enters biogeochemistry circulation.
Summary of the invention
The object of the invention is to remedy the disadvantages of known techniques, provides a kind of preparation side of shock resistance PS modified material
Method.
In order to achieve the above purpose, the present invention the following technical schemes are provided:
A kind of preparation method of shock resistance PS modified material, which comprises the following steps:
(1) by calcene, poly- butyl rubber and silane coupling agent (3-5) in mass ratio: (24-26): (0.5-1) is mixed
It closes, discharges after high-speed stirred spare；
(2) by above-mentioned material and PS resin, zinc stearate, antioxidant (6-10) in mass ratio: (82-86): (4-6): (0.5-
0.8) it is mixed and stirred for uniformly, obtaining mixture；
(3) above-mentioned mixture is put into the hopper of double screw extruder, extruding pelletization is to get PS modified material of the present invention.
The preparation method of the shock resistance PS modified material, which is characterized in that the step 1 high speed speed of agitator control
It is made as 800-1000 revs/min, the time is 10-20 minutes.
The head temperature of double screw extruder is 185-195 DEG C in the step 3, and screw speed is 240-280 revs/min
Clock.
In the step 3, double screw extruder includes six regions successively arranged, and the temperature in the firstth area is 110-130
DEG C, the temperature in the secondth area is 160-180 DEG C, and the temperature in third area is 180-190 DEG C, and the temperature in the 4th area is 190-195 DEG C, the
The temperature in 5th area is 195-205 DEG C, and the temperature in the 6th area is 205-210 DEG C.
The PS modified material can be used for preparing the plastic wire coil that electromagnetic wire coiling uses.
The invention has the advantages that
PS material of the present invention is function modified by the addition progress of Multiple components, and wherein calcene is as inorganic enhancing
Toughening functions filler is used in conjunction with poly- butyl rubber, can enable material when being impacted by crackle after connecting with PS resin
The point stresses of extension are discharged by the rubber grain of flexible relative, are hindered crack propagation with this, are improved shock resistance, making
It by the double-screw extruding pelletizing temperature region accurately controlled in standby technique, enables and more tends to stablize on material structure, have excellent
Shock resistance, tensile property, expand the scope of application, have ideal practical value, be suitble to promote.
Specific embodiment
Below in conjunction with specific example, technical scheme is described further:
A kind of preparation method of shock resistance PS modified material, comprising the following steps:
(1) calcene, poly- butyl rubber are mixed with silane coupling agent 4:25:0.7 in mass ratio, after high-speed stirred
It discharges spare；
(2) above-mentioned material and PS resin, zinc stearate, antioxidant 7:84:5:0.5 in mass ratio are mixed and stirred for uniformly, obtaining
To mixture；
(3) above-mentioned mixture to be put into the hopper of double screw extruder, extruder includes six regions successively arranged, the
The temperature in one area is 115-125 DEG C, and the temperature in the secondth area is 165-175 DEG C, and the temperature in third area is 180-185 DEG C, the 4th area
Temperature be 190-195 DEG C, the temperature in the 5th area is 200-205 DEG C, and the temperature in the 6th area is 205-210 DEG C, twin-screw extrusion
