Embodiment

[0017] Example: A method of using waste PE materials to prepare recycled plastic pipes

[0018] The plastic pipe material formula is recycled high-density PE resin, recycled low-density PE resin, color masterbatch and conventional plastic defoamer; its components are 68.8 kg of recycled low-density PE resin, recycled 29.2 kg of high-density PE resin, 1.5 kg of color masterbatch and 0.5 kg of conventional plastic defoamer.

[0019] The method of manufacturing plastic pipes is:

[0020] The first step is to put 68.8 kg of recycled low-density PE resin, 29.2 kg of recycled high-density PE resin, 1.5 kg of color masterbatch and 0.5 kg of conventional plastic defoamer into the storage tank for pre-mixing;

[0021] The second step is to pump the mixed raw materials into the container of the pumping machine by the vacuum pumping machine for secondary stirring to ensure the uniform distribution of various ingredients;

[0022] The third step is to heat and extrude the raw materials ...

Abstract

The invention discloses a method for preparing a recycled plastic pipe by means of a waste PE material, and belongs to a method for recycling waste plastics. The method is mainly used for solving theproblem that waste plastics pollute the environment. According to the technical scheme, the pipe is prepared from 68.8 kilograms of recycled low-density PE resin, 29.2 kilograms of recycled high-density PE resin, 1.5 kilograms of color masterbatch and 0.5 kilogram of a conventional plastic defoamer through an extrusion forming method, wherein the total weight of the materials is 100 kilograms. Themethod can be used for producing the plastic pipe, and the pipe can be used for conveying water.

Description

technical field [0001] The invention discloses a method for preparing recycled plastic pipes by utilizing waste PE materials. Background technique [0002] Since the invention of plastics, it has been widely used. When it brings great benefits, it also has many negative effects. For example, the increasing pollution of waste plastics to the environment is a huge threat. Among them, the plastic woven bag is discarded after one-time use, which is a kind of great waste and bad behavior that destroys the environment. [0003] Most of the existing woven bags are made of low-density PE resin (LDPE), also known as low-pressure PE and high-density PE resin (HDPE), also known as high-pressure PE plastic materials, which can be completely recycled through regeneration. [0004] The present invention is exactly a kind of successful compensatory attempt of carrying out for this reason. [0005] Rinse and clean the recovered waste plastic woven bags and crush them; then dry them; then ...
