Abstract
The invention belongs to the technical field of polystyrene materials, and particularly relates to a preparation method of a high-rigidity high-gloss polystyrene modified material; the preparation method includes mixing, extruding and pelletizing steps; and according to the preparation method, high rigidity and high gloss properties are obtained by modification of high impact polystyrene.
Description
Technical field
The invention belongs to Polystyrene material technology field, be specifically related to a kind of preparation method of high rigidity high gloss Polystyrene material.
Background technology
By styrene monomer, through the synthetic polystyrene material of free radical polycondensation, be commonly referred to General Purpose Polystyrenre (GPPS), it is a kind of water white general-purpose plastics, cheap, and there is good thermal insulation, insulation and the transparency, but because its matter is crisp, easily split, resistance to impact shock is low, greatly limited its application.Therefore people adopt polydiene and styrene monomer to carry out copolymerization and make high-impact polystyrene (HIPS), improved the toughness of polystyrene material, widened the Application Areas of polystyrene material, high-impact polystyrene (HIPS) has been widely used in the industries such as electronics, electrical equipment, instrument, packing, daily necessities at present.
But rigidity and the glossiness of high-impact polystyrene (HIPS) are poor, in prior art, yet there are no high-impact polystyrene (HIPS) is carried out to modification, make the technology report of high rigidity high gloss Polystyrene material.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of preparation method of Polystyrene material, make it to high-impact polystyrene, carry out modification, obtain the performance of high rigidity and high gloss.
Technical scheme provided by the invention is, a kind of preparation method of high rigidity high gloss Polystyrene material, and its step is as follows, first by each raw material homogenizer stirring and evenly mixing, then proceed in twin screw extruder and melt extrude, cooling, last granulation can make product; Described raw material comprises: high-impact polystyrene, General Purpose Polystyrenre, stablizer, white oil and dyestuff; Wherein the weight content of high-impact polystyrene is 75%-90%, and the weight ratio of General Purpose Polystyrenre and high-impact polystyrene is 1-3:10.
Optimize, described stablizer is oxidation inhibitor.
Optimize, described dyestuff is carbon black.
Optimize, raw material stirs 10min in homogenizer.
Optimize, finally by granulation, make cylindrical pellet product.
Optimize, while extruding, the barrel temperature of twin screw extruder is: back segment 180-210 ℃, stage casing 200-210 ℃, leading portion 215-220 ℃, head temperature 215-220 ℃, head pressure: 4-7Mpa.
In preparation method of the present invention, white oil has improved the dispersiveness of General Purpose Polystyrenre and high-impact polystyrene and has mixed shape, makes the material modified composition that obtains even, stable performance, consistent, if white oil replaces with the auxiliary agents such as other dispersion agents or lubricant, reach above-mentioned effect.
Beneficial effect of the present invention is:
1, the present invention is through the modification to high-impact polystyrene, General Purpose Polystyrenre and high-impact polystyrene cooperatively interact, make Polystyrene material there is high rigidity and high-luster, 60 ° of angles of its glossiness are by 65 of high-impact polystyrene, bring up to 75 ~ 95, flexural strength, by 35Mpa, is brought up to 50 ~ 75Mpa.
2, the present invention does not need to adopt compatilizer, even if material has the feature of good stability, ageing-resistant, easy processing.
3, method provided by the invention need only be through mixing, extrude, granulation just can implement, processing method is simple, easily operates.
4, the present invention can regulate the proportioning of each raw material as required, thereby regulates rigidity and the glossiness of material, has the advantages that to guarantee rigidity of material and glossiness simultaneously.
Embodiment
Below in conjunction with embodiment, illustrate the present invention.
The technical scheme that present embodiment provides is, a kind of preparation method of high rigidity high gloss Polystyrene material, and its step is as follows, first by each raw material homogenizer stirring and evenly mixing, then proceed in twin screw extruder and melt extrude, cooling, last granulation can make product; Described raw material comprises: high-impact polystyrene, General Purpose Polystyrenre, stablizer, white oil and dyestuff; Wherein the weight content of high-impact polystyrene is 75%-90%, and the weight ratio of General Purpose Polystyrenre and high-impact polystyrene is 1-3:10.
Wherein, described stablizer is oxidation inhibitor.
