Embodiment 1

[0029] Waste polystyrene plastic regenerated and modified home appliance special material, by weight, consists of 100 parts of waste polystyrene TV shell crushing material, 8 parts of SEBS, 0.3 parts of EBS, 0.2 parts of calcium stearate, 0.15 parts of zinc stearate composition.

[0030] The specific preparation method is as follows:

[0031] First, after dismantling the scrapped TV sets, the polystyrene scraps are crushed, rubbed, washed, rinsed, and dried, then soaked in salt water, screened out the scraps floating on the salt water, and then washed and dried again to obtain Broken waste polystyrene TV casings. Among them, the brine is composed of 100 parts of industrial water, 8 parts of sodium chloride, and 2 parts of calcium chloride.

[0032] Then add waste polystyrene TV shell broken material, SEBS, EBS, calcium stearate, zinc stearate into the high mixer and mix for 4 minutes to get the premix; put the premix into the twin-screw extruder Internally heated, melted, e...

Embodiment 2

[0035] The difference between this embodiment and Example 1 is that the parts by weight of each component are different, and the parts by weight of each component in this embodiment are as follows:

[0036] 100 parts of waste polystyrene TV casing crushing material, 5 parts of SEBS, 0.1 part of EBS, 0.4 part of calcium stearate, 0.2 part of zinc stearate.

Embodiment 3

[0038] The difference between this embodiment and Example 1 is that the parts by weight of each component are different, and the parts by weight of each component in this embodiment are as follows:

[0039] 100 parts of waste polystyrene TV casing crushing material, 6 parts of SEBS, 0.2 part of EBS, 0.3 part of calcium stearate, 0.1 part of zinc stearate.

Abstract

The invention discloses a recycled waste polystyrene plastic produced special modified material for household appliances, and a preparation method thereof, and the material can be used for solving the problem that, in the existing technology, the recovery rate of polystyrene plastic of television shells is lower, and resource is wasted. The material is composed of the following components in parts by weight: 100 parts of waste polystyrene television shell broken material, 5-8 parts of SEBS, 0.1-0.3 parts of EBS, 0.1-0.5 parts of calcium stearate and 0.1-0.3 parts of zinc stearate, wherein the waste polystyrene television shell broken material is obtained by detaching the waste television, smashing the polystyrene broken material, rubbing, cleaning, rinsing, drying, and soaking in brine, screening, then, cleaning again, and drying. The invention also provides the preparation method of the recycled waste polystyrene plastic produced special modified material for the household appliances. The method can be used for effectively recycling the polystyrene plastic of the waste televisions, and has the advantages of saving resource, protecting environment, lowering the cost, simplifying the preparation process, and the like.

Description

technical field [0001] The invention specifically relates to a special material for recycled and modified waste polystyrene plastics for household appliances and a preparation method thereof. Background technique [0002] Polystyrene is the main raw material for the plastic casing of black home appliances. With the arrival of the peak of domestic black home appliance scrapping, a large amount of waste polystyrene plastics have been produced. However, due to the extremely strict requirements on the appearance of plastics used in home appliances, the polystyrene casing of waste home appliances is only Recycling is in low-end plastic products, such as wood-plastic and home appliance shells produced by workshops. [0003] At present, polystyrene plastics for TV shells are recycled. Due to the impurities in other components and more flame retardants, there are many blisters and flow lines on the appearance, so most waste polystyrene cannot be used in TV shells. The use range of...
