Problems solved by technology

However, with the wide and large application of plastic boxes and plastic products, various waste plastics and waste plastic products are also produced in large quantities. These waste plastics are difficult to degrade in the natural environment and can only be disposed of by incineration or landfill.
However, when incinerated, many harmful gases such as hydrogen chloride will be produced due to high-temperature combustion, which will cause great harm to the environment.
In the landfill process, the toxic substances in the plastic will seep out, causing secondary pollution and affecting the use value of the land.

Abstract

The invention discloses a method for preparing an anti-electrostatic property modified plastic raw material. The method comprises the following steps: (A) cleaning wastes: putting plastic wastes and a mixture, which is prepared from polyethersulfone and polyetherimide through mixing according to the mass ratio of 4: 1, into a pickling tank, soaking for 2 days, then, fishing out and air-drying; (B) crushing the air-dried wastes, heating to melt the wastes, adding ABS (Acrylonitrile-Butadiene-Styrene copolymer), brucite powder, chloromethane, graphite, a nonionic surfactant, benzophenone and a conductive agent, and enabling the raw material to be viscous; (C) extruding the viscous raw material obtained in the step (B) with an extruder, so as to form strips, arranging a cutter in front of the extruder, cutting the strips once every 1mm, so as to form small strips, and enabling the cut small strips to fall onto a water-cooled conveying belt; (D) cooling the small strips by the water-cooled conveying belt during conveying, and bagging until the small strips are conveyed to the tail end, thereby obtaining anti-electrostatic property modified plastic raw material granules, wherein the melting temperature is 180-300 DEG C, and the conveying degree of the water-cooled conveying belt is 8-10 meters. The method is simple in preparation, convenient in use and high in waste utilization ratio.

Description

[0001] technical field [0002] The invention relates to the technical field of plastic raw materials. In particular, it relates to a method for manufacturing an antistatic modified plastic raw material. [0003] Background technique [0004] In people's daily life, various plastic products are used. These plastic products are not easy to degrade after being discarded, and random discarding will cause pollution problems. Therefore, the recycling of these discarded plastic products is a technical problem that needs to be solved. At present, the application of a series of plastics including polyethylene, polypropylene, polyvinyl chloride, polystyrene and polyester covers all aspects of industrial and agricultural production and people's daily life. However, with the wide and large application of plastic boxes and plastic products, various waste plastics and waste plastic products are also produced in large quantities. These waste plastics are difficult to degrade in the natu...
