Embodiment 1

[0025] In this embodiment, a special material for geonet is modified by using waste polyester bottle flakes (PET) and mixed polyethylene waste (PE). The special material for geonet is prepared from the following raw materials in parts by weight Made: 100 parts of PET / PE mixed waste, 6 parts of chlorinated polyethylene, 1.5 parts of maleic anhydride, 2 parts of silane coupling agent, 2 parts of paraffin oil, 0.5 part of ferrous sulfate, wherein the PET / PE mixed The waste consisted of 10wt% polyester bottle flakes (PET) and 90wt% polyethylene mixed waste (PE).

[0026] The above-mentioned geonet special material prepared from polyester waste bottle flakes (PET) and polyethylene mixed waste (PE) is prepared by the following method, including the following steps:

[0027] (1) Separately crush polyester waste bottle flakes (PET) and polyethylene mixed waste (PE) into materials of similar size, clean them, dehydrate and dry them, and then mix them evenly in proportion to obtain PET / ...

Embodiment 2

[0031] In this embodiment, a special material for geonet is modified by using waste polyester bottle flakes (PET) and mixed polyethylene waste (PE). The special material for geonet is prepared from the following raw materials in parts by weight Made: 100 parts of PET / PE mixed waste, 8 parts of chlorinated polyethylene, 1 part of maleic anhydride, 2 parts of silane coupling agent, 1 part of paraffin oil, 0.5 part of ferrous sulfate, wherein the PET / PE mixed The waste consisted of 20 wt% polyester bottle flakes (PET) and 80 wt% polyethylene mixed waste (PE).

[0032] The method adopted in this embodiment to prepare the above-mentioned geonet special material is the same as that in Embodiment 1.

Embodiment 3

[0034] In this embodiment, a special material for geonet is modified by using waste polyester bottle flakes (PET) and mixed polyethylene waste (PE). The special material for geonet is prepared from the following raw materials in parts by weight Made: 100 parts of PET / PE mixed waste, 8 parts of chlorinated polyethylene, 2 parts of maleic anhydride, 3 parts of silane coupling agent, 2 parts of paraffin oil, 0.5 part of ferrous sulfate, wherein the PET / PE mixed The waste consisted of 30wt% polyester bottle flakes (PET) and 70wt% polyethylene mixed waste (PE).

[0035] The method adopted in this embodiment to prepare the above-mentioned geonet special material is the same as that in Embodiment 1.

Abstract

The invention relates to a special geonet material prepared by modifying polyester and polyethylene mixed wastes and a preparation method for the special geonet material, and belongs to the technical field of waste plastic treatment and resource utilization. The preparation method comprises the steps of firstly grinding polyethylene terephthalate (PET) and polyethylene (PE) mixed wastes into materials with similar sizes, cleaning, drying and mixing uniformly to prepare PET/PET mixed wastes; and secondly mixing 100 parts of the prepared PET/PET mixed wastes with 5-10 parts of chlorinated polyethylene, 1-2 parts of maleic anhydride, 1-3 parts of a silane coupling agent, 1-3 parts of paraffin oil and 0.5 parts of ferrous sulfate, and performing extrusion granulation to prepare the special geonet material. The tensile strength of the special geonet material prepared with the method exceeds that of a Beijing Yanshan petrochemical brand-new LDPE-1I2A-1 geonet material; the strength requirement of the special geonet material is fully met; the special geonet material is high in quality and high in value; and the resource utilization of the plastic wastes is realized.

Description

technical field [0001] The invention belongs to the technical field of treatment and resource utilization of waste plastics, and relates to a geonet special material modified from polyester waste bottle flakes and polyethylene mixed waste and a preparation method thereof. Background technique [0002] Existing polyester waste bottle flakes (i.e. polyethylene terephthalate, PET) are generally used alone to blow low-end products such as daily-use packaging bottles and pesticide packaging bottles, polyethylene (PE) mixed waste It is also processed into low-end products such as convenience bags, garbage bags, blown daily-use packaging bottles and pesticide packaging bottles by using a separate recycling method. This kind of extensive recycling has simple processing, poor quality and low utilization value. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a geonet special material modified from...
