Problems solved by technology

[0002] Due to the complex sorting of the scattered plastic daily necessities contained in domestic waste, the sorted plastics contain many impurities, the treatment process is complicated, and the cost is high. Recycling is generally done by landfill or incineration, which not only causes waste of resources, but also easily pollutes the environment
[0003] Even if the scattered plastic daily necessities contained in household garbage are sorted out for reuse, the existing recycling method usually adopts the method of water separation and sorting, which consumes a lot of water. This process has high cost and great environmental pollution. and other disadvantages

Embodiment 1

[0028] A method for recycling plastics provided in this embodiment, the method for recycling plastics is specifically:

[0029] (1) Sorting domestic waste to obtain domestic waste plastics;

[0030] (2) Granulate the sorted garbage plastics;

[0031] (3) Add compatibilizer, coupling agent and filler to plastic granules and stir for 20-30 minutes to modify and make plastic granules. Wherein, the compatibilizer includes the following raw materials in parts by weight: 65 parts of polydimethylsiloxane-methyl methacrylate, and 35 parts of polysiloxane-acrylate. The coupling agent is a silane coupling agent. The filler is diatomaceous earth.

[0032] The compatibility shell improves various mechanical properties such as impact resistance and stretch resistance of the plastic.

[0033] Wherein, the specific method of sorting in the step (1) is:

[0034] a. Dewater domestic waste to obtain solid waste and leachate;

[0035] b. The solid waste is broken into bags to obtain oversi...

Abstract

The invention belongs to the technical field of plastic processing, and provides a method for recycling and reutilizing plastic. The method comprises the steps that (1) household garbage is sorted, and household garbage plastic is obtained; (2) the sorted garbage plastic is subjected to granulating; and (3) a compatilizer, a coupling agent and filler are added into plastic granules to be stirred for 20 min to 30 min, modification is carried out, and plastic granules are manufactured. The method for recycling and reutilizing the plastic is relatively simple, pollution to the environment is small, and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, in particular to a method for recycling plastics. Background technique [0002] Due to the complicated sorting of the scattered plastic daily necessities contained in domestic garbage, the sorted plastics contain many impurities, the treatment process is complicated, and the cost is high. Recycling is generally done by landfill or incineration, which not only wastes resources, but also easily pollutes the environment. [0003] Even if the scattered plastic daily necessities contained in domestic garbage are sorted out for reuse, the existing recycling method usually adopts the method of water separation and sorting, which consumes a lot of water. This process has high cost and great environmental pollution. and other disadvantages. [0004] At present, the reuse of recycled plastics is mainly to modify the recycling, mainly using the following methods: one is to add a compatibilizer ...
