Embodiment 1

[0025] A multi-layer composite high-strength barrier film prepared by recycling waste plastics is composed of three layers, including an outer strength film layer, a middle layer connecting film layer and an inner layer barrier film layer.

[0026] The main raw materials of the strength film layer of the outer layer include recycled PET recycled materials, recycled PE recycled materials, nano-calcium silicate particles treated with silane coupling agents, PE-g-maleic anhydride, and recycled PET modifiers. Among them, recycled PET recycled materials accounted for 46% of the total raw material mass ratio, recycled PE regeneration accounted for 30% of the total raw material mass ratio, nano calcium silicate particles treated with silane coupling agent accounted for 19% of the total raw material mass ratio, PE-g -Maleic anhydride accounts for 3% of the total raw material mass ratio, and recycled PET modifier accounts for 2% of the total raw material mass ratio.

Embodiment 2

[0043] The main raw materials of the strength film layer of the outer layer include recycled PET recycled materials, recycled PE recycled materials, nano-calcium silicate particles treated with silane coupling agents, PE-g-maleic anhydride, and recycled PET modifiers. Among them, recycled PET recycled materials accounted for 55% of the total raw material mass, recycled PE accounted for 26% of the total raw material mass, silane coupling agent-treated nano-calcium silicate particles accounted for 14% of the total raw material mass, PE-g -Maleic anhydride accounts for 3.2% of the total raw material mass ratio, and recycled PET modifier accounts for 1.8% of the total raw material mass ratio.

[0044] The preparation method of the nano-calcium silicate particles treated with the silane coupling agent is as follows: a small amount of ethanol-dispersed silane coupling agent and nano-calcium silicate particles are put into a high-speed mixer and stirred at a high speed for 10-20 min...

Abstract

The invention relates to a multilayered composite high-strength barrier film material prepared by adopting recovered waste PET bottles, PE bottles and recovered paperboard fiber as main materials. The composite film material is obtained by composition of three layers of films and comprises an outer strength layer, a middle connecting layer and an inner barrier layer. The composite film has excellent strength and barrier property, can be widely utilized in the field of various strength films, is mostly made by recovered and reused wastes, is low in cost, is beneficial to environmental protection and has great promotion values.

Description

technical field [0001] The invention relates to a method for preparing a high-strength barrier film, in particular to a method for preparing a multi-layer composite high-strength barrier film using recycled plastic waste as the main raw material. Background technique [0002] With the rapid development of modern synthetic resin industry, the application of plastic products is becoming more and more extensive. While plastic products bring convenience to people, a large amount of waste plastics also cause serious pollution to the environment. The use cycle of plastics is very short, and a large number of plastic products are discarded after about 6 to 12 months. 40% of plastics It can no longer be used after 1-2 years. In the past few decades, waste plastics have been regarded as part of municipal solid waste (MSW), and waste plastics account for 4%-10% (wt) or 10%-20% (vol) in MSW in developed countries. In recent years, with the implementation of the law on the promoti...
