Abstract
The invention belongs to the technical field of modified polystyrene materials, and particularly relates to high rigidity high gloss polystyrene resin; the composition comprises the following raw materials: high impact polystyrene, general purpose polystyrene, a stabilizer, a processing aid and a dye; and high rigidity and high gloss performances are obtained by modification of the high impact polystyrene.
Description
Technical field
The invention belongs to Polystyrene material technology field, be specifically related to a kind of high rigidity high gloss polystyrene resin.
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 resin.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of polystyrene resin, 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 high rigidity high gloss polystyrene resin, and it is comprised of following raw material: high-impact polystyrene, General Purpose Polystyrenre, stablizer, processing aid and dyestuff; Wherein the weight content of high-impact polystyrene is 75%-90%, and the weight content of General Purpose Polystyrenre is 5%-25%, and stablizer, processing aid and dyestuff are surplus.
Optimize, described processing aid is white oil.
Optimize, described stablizer is oxidation inhibitor.
Optimize, described dyestuff is carbon black.
The preparation method of above-mentioned high rigidity high gloss polystyrene resin provided by the invention, its step is as follows, first by each raw material according to weight content homogenizer stirring and evenly mixing, then proceed in twin screw extruder and melt extrude, cooling, last granulation can make product.
Beneficial effect of the present invention is:
1, the present invention, through the modification to high-impact polystyrene, makes poly styrene polymer have high rigidity and high-luster, and 60 ° of angles of its glossiness, by 65 of high-impact polystyrene, bring up to 75 ~ 95, and 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, 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 high rigidity high gloss polystyrene resin, and it is comprised of following raw material: high-impact polystyrene, General Purpose Polystyrenre, stablizer, processing aid and dyestuff; Wherein the weight content of high-impact polystyrene is 75%-90%, and the weight content of General Purpose Polystyrenre is 5%-25%, and stablizer, processing aid and dyestuff are surplus.
Wherein, described processing aid is white oil.
Wherein, described stablizer is antioxidant 1010, i.e. chemical name: four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester.
Wherein, described dyestuff is carbon black.
The preparation method of the above-mentioned high rigidity high gloss polystyrene resin that present embodiment provides, its step is as follows, first by each raw material according to weight content homogenizer stirring and evenly mixing, then proceed in twin screw extruder and melt extrude, cooling, last granulation can make product.
Wherein, raw material stirs 10min in homogenizer.
Wherein, finally by granulation, make cylindrical pellet product.
Wherein, 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.
The present invention provides four kinds high rigidity high gloss polystyrene resins according to above-mentioned formula and preparation method, be designated as sample 1-4, wherein the raw material weight proportioning of each sample is as described in Table 1, and contrast with high-impact polystyrene, glossiness and the flexural strength of having tested each sample, be recorded in table 1.
Table 1
| ? | Sample 1 | Sample 2 | Sample 3 | Sample 4 | High-impact polystyrene |
| Raw material | Weight part | Weight part | Weight part | Weight part | —— |
| High-impact polystyrene | 100 | 100 | 100 | 100 | —— |
| General Purpose Polystyrenre | 10 | 20 | 25 | 30 | —— |
| Oxidation inhibitor | 0.5 | 0.5 | 0.5 | 0.5 | —— |
| Carbon black | 1 | 1 | 1 | 1 | —— |
| White oil | 0.2 | 0.2 | 0.2 | 0.2 | —— |
| Glossiness (60 ° of angles) | 78 | 82.5 | 87 | 95 | 65 |
| Flexural strength (Mpa) | 52.1 | 59.8 | 65 | 74.3 | 35 |
From upper table, contrasted: glossiness and the flexural strength of polyphenylacetylene combination sample provided by the invention are better than high-impact polystyrene, so the present invention is better than prior art.
Present embodiment has following features:
1, present embodiment is through the modification to high-impact polystyrene, General Purpose Polystyrenre and high-impact polystyrene cooperatively interact, make poly styrene polymer 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, present embodiment does not need to adopt compatilizer, even if material has the feature of good stability, ageing-resistant, easy processing.
3, present embodiment 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.
