Abstract
The invention discloses a modified polystyrene material which comprises the following raw materials in percentage by weight: 65-90% of polystyrene resin, 8-30% of styrene-butadiene copolymer and 1-5% of liquid paraffin. The raw materials according to the formula are proportionally added, and a mixer is started to mix the raw materials for 5 minutes; and the mixture can be directly put into a common injection molding machine for production without drying the raw materials. The transparency of the modified GPPS (general purpose polystyrene) material disclosed by the invention remains the transparency of the original GPPS material, the elongation at break is enhanced from 2% to 5%, and the impact strength can be enhanced from 3KJ/m<2> to 15KJ/m<2>.
Description
Technical field:
The present invention relates to a kind of transparent material, the modified polystyrene material on the transparent plastic articles such as being applied in the refrigerator lampshade of more specifically saying so.
Background technology:
At present, the lampshade material that is applied on the refrigerator is that PC (polycarbonate) material is injection molded substantially, later stage is because PC is on the high side, change into and use PCTA (copolyester) material substitution PC, but under precondition, PC and PCTA material price are all higher, consider for the angle that reduces cost, and need seek the injection moulding that new material substitution PC and PCTA material are used for lampshade.Common GPPS material because shock strength is poor, when injection moulding and later stage assembling, the cracking situation can occur when producing baroque Transparent Parts such as lampshade.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of method of modifying that can improve GPPS toughness and not influence the material transparency, make modification GPPS material can successfully substitute PC material and copolyester material.
Technical solution problem of the present invention adopts following technical scheme:
Modified polystyrene material comprises following raw materials by weight percent:
Polystyrene resin (GPPS): 65-90%
Styrene-butadiene copolymer (K resin): 8-30%
Whiteruss (white oil): 1-5%
It is low-cost that the present invention mainly provides a kind of use, and the modification GPPS material of high impact strength, high-clarity is applied in the refrigerator lampshade.Use the common plastic mixer required various raw materials of will filling a prescription to add in proportion, start and get final product after stirrer stirs 5min, stirred materials can directly drop into common injection moulding machine and can produce, and need not starting material are carried out drying treatment.If the dispersiveness to raw material has higher requirement, need that then above material is dropped into homogenizer in proportion and stir, stir by the cooling and stirring machine then, after dropping into dual-screw pelletizer again and carrying out granulation, can carry out ordinary production dropping into injection moulding machine.The adding proportion of control styrene-butadiene copolymer (K resin) is the difficult point in the process, if ratio is improper, because the influence of the specific refraction of two kinds of materials can make transparency of products descend significantly.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Material of the present invention is a major ingredient with common GPPS material, in the GPPS material, add a certain proportion of K resin (styrene-butadiene copolymer) and improve its toughness, the purpose of adding toner (optional raw material) mainly is that material is dyeed, and the purpose of adding white oil is to improve dispersiveness.Above material is by after the twin screw granulation, and the modification GPPS material transparency that processes can keep the transparency of original GPPS material, and elongation at break brings up to 5% from 2%, and shock strength is from 3KJ/m
2Can bring up to 15KJ/m
2
1, reduces material cost, comprise unit price, manufacturing expense, weight etc.Attached cost analysis:
The price of K resin: 18000 yuan/ton
GPPS price: 10500 yuan/ton
The price of modification GPPS material: 11250 yuan/ton
The price of PC and copolyester: 20000 yuan/ton
After using the GPPS material, material is per ton to reduce cost 8750 yuan.
The proportion of modification GPPS is: 1.03g/cm3
The proportion of PC and copolyester is: 1.20g/cm3
After using the GPPS material, product weight can reduce by the 16.5% (density of modification GPPS material: 1.03g/cm
3, the density of PC material is 1.20g/cm
3).
Drying-free when producing behind the use GPPS material, PC and copolyester must 120 ℃ of dry 4h.
2, materials procurement channel of the present invention is simple, the modifying process stable performance.
3, the modification GPPS materials processing performance of the present invention's generation is better than original material, and feed back is easy to reuse.PC and copolyester are owing to the flavescence of being heated easily, and feed back can not reuse.
4, moulding good fluidity, technology is simple, and processing temperature is low, drying-free.And the difficult moulding of PC material, the processing temperature height, time of drying is long.
Below by embodiment, the invention will be further described.
