The modified regeneration high impact polystyrene mainly comprises the following components by weight percentage: 10%-50% of high impact polystyrene, 15%-80% of recycled high impact polystyrene, 5%-20% of toughening agent, 5%-40% of calcium carbonate, 0.1%-1% of antioxygen 1010, 0.3%-1% of silane coupling agent and 0.4%-2% of pigment. The invention also provides the preparation method of the modified regeneration high impact polystyrene for the tubes and pipe fittings. The preparation method can be used for effectively recycling waste high impact polystyrene. The modified regeneration high impact polystyrene for the tubes and pipe fittings has the advantages that resources are saved, the environment is protected, the cost is lowered, the preparation process is simplified and the like.
Description
Technical field
What the present invention relates to is a kind of high-impact polystyrene, is meant that specifically tubing, pipe fitting are with modification regeneration high-impact polystyrene and preparation method thereof.
Background technology
Existing high-impact polystyrene (HIPS) is to form through the graft copolymerization manufactured, and soon elastomerics, carries out mass polymerization or suspension polymerization then and makes in PS with minimum microparticulate, and its manufacturing cost is higher, and method is complicated, and production requirement is higher.
Summary of the invention
The objective of the invention is to solve that existing high-impact polystyrene production cost is high, the problem of complex manufacturing, provide a kind of high-impact polystyrene that utilizes recovery that production cost is reduced and specific aim applies to tubing, pipe fitting on tubing, the pipe fitting with modification regeneration high-impact polystyrene and preparation method thereof.
Realize that technical scheme of the present invention is following:
Tubing, pipe fitting are used the modification regeneration high-impact polystyrene, mainly are made up of following components in weight percentage:
High-impact polystyrene 10%～50%
Reclaim high-impact polystyrene 15%～80%
Toughner 5%～20%
Lime carbonate 5%～40%
Antioxidant 1010 0.1%～1%
Silane coupling agent 0.3%～1%
Pigment 0.4%～2%.
Further, said recovery high-impact polystyrene is the sheet stock that waste and old high-impact polystyrene obtains after fragmentation, cleaning, oven dry, homogenizing.
Further, the fineness of said lime carbonate is 2500 orders.
Tubing, pipe fitting are made up of following steps with the preparation method of modification regeneration high-impact polystyrene:
(1) high-impact polystyrene, recovery high-impact polystyrene, toughner, lime carbonate, antioxidant 1010, silane coupling agent, pigment mix under high-speed condition, make the material that is mixed;
(2) extrude and promptly process finished product with the forcing machine material that will be mixed.
For the more effective mixing of carrying out each component of ability, all components mixes in proportioning machine in the said step (1).
In order better to realize the present invention, the forcing machine that adopts in the said step (2) is a twin screw extruder.
As a kind of preferred, said finished product is processed particle.
The present invention has the following advantages and beneficial effect:
1, the present invention will reclaim high-impact polystyrene and match with other components and process the modification regeneration high-impact polystyrene that is exclusively used on tubing, the pipeline; And existing the discovery utilizes waste and old material to process the thinking that is exclusively used in the material on tubing, the pipeline; Have on the document that also has no about utilize reclaiming high-impact polystyrene and process the report of the modification regeneration high-impact polystyrene that is exclusively used on tubing, the pipeline, and then can derive the present invention and have very high creativeness.
2, the prescription of putting down in writing among the present invention is not only because of utilizing the recovery high-impact polystyrene that its cost is reduced greatly; And then the business economic remarkable benefit is improved; But also can resource be utilized effectively through recycling waste and old out of use high-impact polystyrene; Thereby alleviate the pollution of environment effectively, realize the substantive distinguishing features of sustainableization development.
3, adopt prescription of the present invention, not only can produce qualified tubing, pipe fitting is used the modification regeneration high-impact polystyrene, and utilize its tubing of processing, pipe fitting performance to be superior to tubing, the pipe fitting that utilizes brand-new high-impact polystyrene to produce at present.
4, adopt method of the present invention, not only can prepare qualified finished product effectively, and operating process is very simple, and be fit to apply.
5, the lime carbonate that adopts of the present invention is 2500 orders, and all components mixes in proportioning machine, each component is mixed, thereby effectively guarantee the quality of finished product.
6, the present invention adopts twin screw extruder; Have fricative heat is less, material is suffered shearing relatively evenly, the transport capacity of screw rod is big, extrusion capacity is more stable, material residence time progress and make all components mix advantage of uniform more in machine barrel; And then the efficient and the quality of assurance production effectively, satisfy user's demand substantially.
7, finished product of the present invention is processed particle, can be when using particle of the present invention to process tubing, pipe fitting, and hot melt institute energy requirement is lower, and the waste of the energy when avoiding effectively utilizing finished product of the present invention to process tubing, pipe fitting reaches the purpose of saving.
