Embodiment 1

[0031] Modified recycled high-impact polystyrene for pipes and fittings, mainly composed of 22% high-impact polystyrene, 55% recycled high-impact polystyrene, 8% toughening agent, 10% calcium carbonate, 0.1% antioxidant 1010, 0.4% silane coupling agent, 1.5% pigment.

[0032] The specific preparation method is as follows:

[0033] First, waste high-impact polystyrene is crushed, cleaned, dried, and homogenized to obtain recycled high-impact polystyrene.

[0034] Add recycled high-impact polystyrene and other components into the batching machine, stir at a high speed in the batching machine and mix evenly, and the mixed material will be made after mixing evenly. Put the mixed material into the twin-screw extruder, use the extruder to extrude the mixed material to make strips, and cut them into granules. The granular material is the finished product of the present invention.

Embodiment 2

[0036] The difference between this embodiment and Example 1 is that the percentage content of each component is different, and the percentage content of each component in the present embodiment is as follows:

[0037] 5% high impact polystyrene, 70% recycled high impact polystyrene, 10% toughening agent, 13% calcium carbonate, 0.5% antioxidant 1010, 0.7% silane coupling agent, 0.8% pigment.

Embodiment 3

[0039] The difference between this embodiment and Example 1 is that the percentage content of each component is different, and the percentage content of each component in the present embodiment is as follows:

[0040] 50% high impact polystyrene, 15% recycled high impact polystyrene, 5% toughening agent, 26% calcium carbonate, 1% antioxidant 1010, 1% silane coupling agent, 2% pigment.

Abstract

The invention discloses modified regeneration high impact polystyrene for tubes and pipe fittings and a preparation method of the high impact polystyrene, which solve the problems of high cost and complex method of the conventional high impact polystyrene for the tubes and pipe fittings. 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 [0001] The invention relates to a high-impact polystyrene, in particular to modified and regenerated high-impact polystyrene for pipes and fittings and a preparation method thereof. Background technique [0002] The existing high-impact polystyrene (HIPS) is produced by graft copolymerization, that is, the elastomer is dispersed in polystyrene with very small particles, and then bulk polymerization or suspension polymerization is carried out, and its manufacturing cost is relatively low. High, complex methods, high production requirements. Contents of the invention [0003] The purpose of the present invention is to solve the problems of high production cost and complex production process of the existing high-impact polystyrene, and provide a kind of production cost reduction by using recycled high-impact polystyrene and targeted application on pipes and pipe fittings. Modified recycled high-impact polystyrene for pipes and pipe fittings and a preparation ...
