The content of the invention
It is an object of the invention to provide a kind of lower shrinkage, high thermal stability impact-resistant polystyrene material and its preparation side
Method, it is possible to reduce deformations of the high-impact HIPS when being heated, it is ensured that the assembling of product and use.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of lower shrinkage, high thermal stability impact-resistant polystyrene material, including following weight portion component：
Further scheme, the high-impact polystyrene resin refers to the melt flow rate (MFR) under the conditions of 200 DEG C/5kg
It is the polystyrene resin of 2-10g/10min.
Further scheme, the toughener is styrene-butadiene-polystyrene block copolymer SBS or polyphenyl second
Alkene-Ethylene/Butylene-polystyrene triblock copolymer SEBS.
Further scheme, the filling reinforcing agent is talcum powder, and the particle diameter for filling reinforcing agent is 1-10 μm.
Further scheme, the antioxidant is four [β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol esters
With three [2.4- di-tert-butyl-phenyls] phosphite esters with 1:The weight of 1-2 is formed than compounding.
Further scheme, the lubricant is the one kind in calcium stearate, Tissuemat E, ethylene bis stearamide, silicone
Or several mixtures.
It is another object of the present invention to provide a kind of lower shrinkage, high thermal stability impact-resistant polystyrene material, system
Preparation Method, comprises the following steps：
(1) high-impact polystyrene resin, toughener, filling reinforcing agent, antioxidant and profit are weighed by above-mentioned part by weight
Lubrication prescription, releases after mixing 5-10min in high-speed mixer together；
(2) above-mentioned mixed material addition double screw extruder is carried out into melting mixing, is extruded, cooling, pelletizing, drying are
Lower shrinkage of the invention, high thermal stability material are obtained, the temperature range that each section of extruder is 170-210 DEG C.
Beneficial effects of the present invention：
(1) present invention in lower shrinkage, high thermal stability impact-resistant polystyrene materials process is prepared by add toughener,
Filling reinforcing agent, antioxidant and lubricant, obtained polystyrene material shrinkage factor within 0.5%, at a higher temperature
With good dimensional stability, the temperature in use scope of material is expanded and increased HIPS dimensionally stables at relatively high temperatures
Property；
(2) lower shrinkage, high thermal stability impact-resistant polystyrene material prepared by the present invention, the detection mark according to the industry
Standard, notch impact strength is more than 9KJ/m2, bending modulus be more than 2000MPa, show good toughness.
Specific embodiment
The present invention is described in further detail with reference to specific embodiment.
The all raw materials of the present invention are commercially available.
Toughener is styrene-butadiene-polystyrene block copolymer SBS or polystyrene-second in embodiment 1-5
Alkene-butylene-polystyrene triblock copolymer SEBS；Filling reinforcing agent is the talcum powder that particle diameter is 1-10 μm；Antioxidant is four
[β-(3,5- di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester and three [2.4- di-tert-butyl-phenyls] phosphite esters are with 1:
The weight of 1-2 is formed than compounding；Lubricant be calcium stearate, Tissuemat E, ethylene bis stearamide, silicone in one kind or
Several mixtures.
Lower shrinkage, high thermal stability impact-resistant polystyrene material in embodiment 1-5 be the raw material shown in table 1 by weight
Part composition, specific preparation method is comprised the following steps：
