Problems solved by technology

[0003] (1) Incineration or landfill method, since harmful gases such as sulfur dioxide are generated during the incineration process, it is very easy to cause environmental pollution, and the landfill method is a waste of land The refractory nature of resources and materials will also cause great harm to the environment, and this method is currently being phased out;
[0004] (2) Simple recovery and granulation of waste electrical shell materials, defective materials, defective products or recycled products without any scientific and technological modification, downgraded to Although the use of ordinary plastics has solved the problem of environmental pollution, the economic value of these secondary materials has not been fully utilized, and the flow of inferior materials to the market will have serious consequences, resulting in the emergence of inferior products

Abstract

The invention discloses high-performance polypropylene alloy prepared through waste and old polypropylene materials and a preparation method and application of the high-performance polypropylene alloy. According to the prescription of raw materials, the polypropylene alloy comprises the following components by weight: 60 to 85 parts of polypropylene, 0.2 to 0.4 part of B-215 long-acting heat stabilizer, 5 to 10 parts of EPDM (Ethylene-Propylene-Diene Monomer) and 10 to 30 parts of BaSO4. The polypropylene alloy disclosed by the invention has the characteristics of high performance, scratching resistance, low temperature resistance, good fire resistance, ageing resistance, and the like; and the polypropylene alloy can be applied to preparing housings of an electric fan and an electric cooker, manufacturing a showing stand or a car bumper, has resistance to high temperature of 80 DEG C and resistance to low temperature of minus 40 DEG C, and has the service life being over 20 years.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the recycling technology of waste plastics, in particular to the technology of preparing high-performance polypropylene alloys from waste polypropylene materials. Background technique [0002] Polypropylene (PP) is a very commonly used material, so it is widely used in the preparation of electrical housing materials, automotive materials or display rack materials, etc. There are a lot of old materials and waste materials in each period. In the production process, a large number of inferior materials or defective products and recycled products will be produced. At present, there are mainly the following methods for the treatment of waste materials, inferior materials, defective products or recycled products: [0003] (1) Incineration or landfill method, because harmful gases such as sulfur dioxide are generated during the incineration process, it is easy to cause environ...
