Problems solved by technology

[0004] At present, the commonly used treatment methods for waste high-impact polystyrene plastics mainly include the following: landfill is the simplest treatment method; but landfill is not only difficult to degrade and occupies land, but also harmful substances in plastics such as pigments and plasticizers Additives such as additives may also dissolve, causing secondary pollution of the soil
Incineration is also a relatively common treatment method, but a large amount of toxic and harmful gases will be produced during the incineration process, such as dioxins, polychlorinated dibenzofurans, etc., causing new environmental pollution
Simple regeneration and granulation without any modification; the performance of high-impact polystyrene plastic after use decreases, and simple granulation can only be downgraded to ordinary materials. Although it is better than direct landfill and incineration, it still cannot make full use of HIPS plastic value

Abstract

The invention relates to the technical field of modification treatment of waste plastics, in particular to modified high-impact polystyrene plastic. The modified high-impact polystyrene plastic comprises, by weight, 85-95 parts of waste high-impact polystyrene plastics, 2-15 parts of high-impact polystyrene resin, 2-10 parts of flexibilizers, 0.1-0.4 part of heat stabilizers, 0.1-0.4 part of antioxidants, 0.1-0.3 part of ultraviolet absorbers and 1-3 parts of dispersing agents. By adding certain quantities of novel high-impact polystyrene and plastic additives, the impact resistance of the waste HIPS (high-impact polystyrene plastic) is increased while the tensile strength and the flexure strength of the plastic are guaranteed, mechanical properties of the plastic reach standards of fresh materials, the waste HIPS plastic can be recovered effectively, and affection to environments is low.

Description

technical field [0001] The invention relates to the technical field of modification treatment of waste plastics, in particular to the modification of waste high-impact polystyrene plastics. Background technique [0002] The rapid update of electronic and electrical products has produced a large amount of waste plastics, causing serious environmental pollution and a great waste of resources. In 2002, the European Parliament issued the 2002 / 96 / EC resolution "Waste of Electronic and Electrical Products", referred to as the WEEE Directive, which aims to strengthen the prevention and control of waste electronic and electrical waste by controlling the recycling process of waste electronic and electrical products Realize its recycling and utilization, reduce resource consumption and damage to the environment. In 2010, my country promulgated the "Regulations on the Administration of Recycling and Disposal of Waste Electronic Products", which came into effect on January 1, 2011. Th...
