Embodiment 1

[0037] Modified recycled high-impact polystyrene special materials for home appliances, mainly composed of 20% polystyrene, 55% recycled polystyrene, 10% toughening agent, 6% talcum powder, 5% calcium carbide, 1% impact modifier, 0.1% dicumyl peroxide, 0.4% antioxidant 1010, 0.5% silane coupling agent, 0.5% EVA wax, 0.5% stearic acid, 1% composition of pigments.

[0038] The specific preparation method is as follows:

[0039] First, waste polystyrene is crushed, washed, dried, and homogenized to obtain recycled polystyrene.

[0040] Add recycled polystyrene and other components into the batching machine, stir in the batching machine at high speed for 5 minutes and mix evenly, and then make the mixed material 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

[0042] 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:

[0043] 40% Polystyrene, 20% Recycled Polystyrene, 13% Toughener, 10% Talc, 10% Calcium Carbide, 2% Impact Modifier, 0.5% Diisoperoxide Propylbenzene, 1% antioxidant 1010, 1% silane coupling agent, 1% EVA wax, 1% stearic acid, 0.5% pigment, and the high-speed stirring time in the batching machine is 6 minutes.

Embodiment 3

[0045] 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:

[0046] 11% polystyrene, 63% recycled polystyrene, 6% toughener, 7% talc, 6% calcium carbide, 3% impact modifier, 0.3% diisoperoxide Propylbenzene, 0.7% antioxidant 1010, 0.8% silane coupling agent, 1.2% EVA wax, 0.6% stearic acid, 0.4% pigment, and the high-speed stirring time in the batching machine is 7 minutes.

Abstract

The invention discloses a modified renewable high impact polystyrene special material for household appliances and a preparation method thereof, and solves the problem that the special material for household appliances is high in production cost and complicated in production process in the prior art. The special material disclosed by the invention is mainly composed of the following components in percentage by weight: 10-75% of polystyrene, 10-80% of recycled polystyrene, 5-20% of toughener, 5-40% of talcum powder, 5-40% of calcium carbonate, 1-5% of impact modifier, 0.1-2% of diisopropylbenzene peroxide, 0.4-2% of antioxidant 1010, 0.5-3% of silane coupling agent, 0.5-3% of EVA (ethylene-vinyl acetate) wax, 0.5-3% of stearic acid and 0.4-4% of pigment. The invention also provides the preparation method of the modified renewable high impact polystyrene special material for household appliances. The invention can effectively recycle waste polystyrene, and has the advantages of resource saving, environment protection, cost reduction, simplified preparation process and the like.

Description

technical field [0001] The invention belongs to the technical field of waste polystyrene recycling and specifically relates to a special material for modified and regenerated high-impact polystyrene used in household appliances and a preparation method thereof. Background technique [0002] Polystyrene has the advantages of high gloss, good insulation, good heat resistance and good fluidity, and can be widely used in the preparation of air-conditioning chassis, office supplies, toys, food packaging, CD pieces, radio and TV casings. However, due to the wide use, polystyrene waste is increasing day by day, which not only causes serious pollution to the environment, but also forms a great waste of resources. The manufacturing cost of existing special materials for household appliances is relatively high, and the production process is complicated. Contents of the invention [0003] The purpose of the present invention is to provide a modified recycled high-impact polystyrene ...
