Abstract
The invention belongs to the field of chemical technology, specifically to a product formula for modified material of HIPS resin back material and use method thereof. The preparation method for the modified material of HIPS resin back material is as follows: putting the HIPS resin back material into a vibrating screen, and removing off dust, and sequentially adding HIPS resin back material after dust removal, white oil, SBS resin, EBS resin and anti-oxidant into a high-speed mixer, and mixing them for 5-15 min at a high speed, and discharging the mixed material which is the modified material of HIPS resin back material. The modified material of HIPS resin back material is put into a feed hopper of an injection molding machine and is directly injection molded into products, or is put into a feed hopper of sheet material extruder and extruded into sheet material. The modified material of HIPS resin back material has good tensile property, high impact strength and low production cost. The property of the modified material of the back material surpasses that of the raw material such that the modified material can be used in replacement of the HIPS raw material.
Description
Technical field
The invention belongs to chemical technology field, relate to a kind of HIPS resin feed back modifying material and using method thereof.
Background technology
HIPS resin is a kind of organic polymer material be prepared from for raw material with vinylbenzene and cis-1,4-polybutadiene rubber, its purposes is wider, large usage quantity, usually for the various daily living article of injection moulding and plastic toys goods, as for the production of the housing of conditioner, televisor, computer, washing machine, refrigerator, suction cleaner etc. and component, for the preparation of sheet material, the housing and component etc. of the light current device of electrician, telecommunication, instrument.HIPS resin in use can produce many wasters and regrinding-material, these wasters and regrinding-material just become feed back after crushed, the performance of the Performance Ratio raw material of feed back reduces many, if with these feed back direct production goods, goods will become very crisp, occur the phenomenons such as disconnected muscle, disconnected pawl.For this reason, many factories all have a headache for the use of these HIPS resin feed backs, some factory just by the feed back of HIPS resin in 10% ratio be added in virgin material and use, but do the performance that can reduce product on the one hand like this, feed back can not fall in complete digestion on the other hand, remaining feed back have to be regarded Treatment of Waste Plastics and be fallen, and does like this and production cost will be made to increase.In order to solve the problem, study a kind of HIPS resin feed back modifying material and using method just seems very urgent.
Summary of the invention
The object of this invention is to provide a kind of using method making it the modification of HIPS resin feed back become a kind of HIPS resin feed back modifying material and this feed back modifying material.
In order to achieve the above object, HIPS resin feed back is put into vibratory screening apparatus to screen out dust by the preparation method of a kind of HIPS resin feed back modifying material of the present invention, then add in high-speed mixer by screening out HIPS resin feed back, white oil, SBS resin, EBS and oxidation inhibitor after dust successively, open high-speed mixer, high-speed mixing is after 5 ~ 15 minutes, released by mixed material, this compound is HIPS resin feed back modifying material.Then HIPS resin feed back modifying material is put into the loading hopper of injection moulding machine, its direct injection moulding is gone out goods, or loading hopper HIPS resin feed back modifying material being put into plate-extruding machine is processed into sheet material.The formula composition of HIPS resin feed back modifying material and weight percent are: HIPS resin feed back 90 ~ 95%, white oil 0.2 ~ 1%, SBS resin 2 ~ 8%, EBS 1 ~ 2%, oxidation inhibitor 0.1 ~ 0.3%.
Oxidation inhibitor in formula is antioxidant 1010, or is irgasfos 168, or is the compound of antioxidant 1010 and irgasfos 168.
The specific embodiment of the present invention is:
HIPS resin feed back is put into vibratory screening apparatus and screens out dust, then according to formula composition and the weight percent of HIPS resin feed back modifying material, HIPS resin feed back after dust will be screened out successively, white oil, SBS resin, EBS and oxidation inhibitor add in high-speed mixer, open high-speed mixer, after mixing 5 ~ 15min, the material in high-speed mixer is released, this compound is HIPS resin feed back modifying material, then HIPS resin feed back modifying material is put into the loading hopper of injection moulding machine, its direct injection moulding is gone out goods, or HIPS resin feed back modifying material is put into the loading hopper of plate-extruding machine, be extruded into HIPS sheet material.
The invention has the beneficial effects as follows, HIPS resin feed back modifying material has the advantages that tensile property is good, shock strength is high, production cost is low, HIPS resin feed back modifying material directly uses the material property reduction avoiding feed back secondary granulation and cause, decrease feed back granulation cost, ensure that material property, avoid environmental pollution.
HIPS resin feed back modifying material and HIPS raw material, HIPS feed back and HIPS feed back modification granulation material performance see the following form 1:
The performance comparison table of table 1:HIPS resin feed back modifying material and HIPS raw material, HIPS feed back and HIPS resin feed back modification granulation material
| Sequence number | Test event | HIPS raw material | HIPS feed back | HIPS resin feed back modification granulation material | HIPS resin feed back modifying material |
| 1 | Tensile strength/Mpa | 33 | 32 | 28 | 36 |
| 2 | Shock strength/kj/m 2 | 12.5 | 8.2 | 12 | 15.2 |
| 3 | Elongation at break % | 20 | 6.4 | 10 | 22 |
| 4 | Rockwell hardness/HRL | 85 | 84 | 85 | 85 |
| 5 | Melt flow rate (MFR) g/10min | 3.5 | 3.6 | 4.0 | 4.2 |
The performance of the Performance Ratio HIPS raw material of HIPS resin feed back modifying material, HIPS feed back and HIPS resin feed back modification granulation material all will be got well as can be seen from the table, above-mentioned HIPS resin feed back modification granulation material is exactly that feed back modifying material its degradation after granulation is more by the granulation again of HIPS resin feed back modifying material.HIPS feed back modifying material is directly used in injecting products or extruded product, can either material property be ensured like this, the cost of feed back granulation can be saved again.
