Embodiment Construction

[0009] The process of recycling waste plastics, the specific steps are as follows:

[0010] (1) A set of automatic flow production line is composed of a crushing and cleaning machine and a traction granulator. After the waste polyethylene plastic is broken, it is cleaned by the washing barrel, rinsed for the second time in the pool, and dried to make waste polyethylene. Plastic particles;

[0011] (2) Stir and mix waste polyethylene plastic particles with polyethylene raw materials, activators, compatibilizers, plasticizers, antioxidants, lubricants, plasticize and filter, and finally cut into granular plastics;

[0012] The proportioning relationship between waste polyethylene plastic and other raw materials is as follows by weight percentage: waste polyethylene plastic is 65%, polyethylene raw material is 15%, filler is 15%, compatibilizer is 1%, plasticizer is 1%, antioxidant 1%, activator 1%, lubricant 1%.

[0013] The filler is mica, or a mixture of mica and glass fiber...

Abstract

The invention provides a waste plastic recycling process method, aiming to solve the problems of occupation of land resources and environmental pollution caused by waste plastic recycling at present. In the technical scheme, the waste plastic recycling process method comprises the following steps: (1) crushing waste polyethylene plastic, cleaning with a washing barrel, rinsing again in a water tank, drying, and obtaining waste polyethylene plastic particles; and (2) uniformly mixing the waste polyethylene plastic particles with raw polyethylene materials, activators, compatilizers, plasticizers, antioxidants and lubricants, carrying out plasticization and filtration, and finally cutting to obtain granulated plastic. The waste polyethylene plastic and other raw materials are mixed according to the following weight percentage: 60-65 percent of the waste polyethylene plastic, 15-16 percent of the raw polyethylene materials, 15-20 percent of fillers, 1 percent of the compatilizers, 1 percent of the plasticizers, 1 percent of the antioxidants, 0.5-1 percent of the activators and 0.5-1 percent of the lubricants.

Description

technical field [0001] The invention relates to a process method for recycling waste plastics. Background technique [0002] In my country, about 14 million tons of waste plastics are not recycled every year, the recycling rate is only 25%, and the direct waste of resources is as high as 28 billion yuan. [0003] The recycling of waste plastics mainly includes physical recycling and chemical recycling. At present, the main methods used in the treatment of waste plastics in my country are landfill treatment and incineration treatment. There are serious disadvantages in landfill treatment: ① Due to the small density and large volume of plastic waste, it takes up a large space and increases the pressure on land resources; ② Plastic waste is difficult to degrade and will become permanent garbage after landfilling. Seriously hinder the penetration of water and the circulation of groundwater; ③The dissolution of additives in plastics such as plasticizers or colorants will also c...
