Production process for separating and recycling paper-plastic composites

Abstract

The invention discloses a production process for separating and recycling paper-plastic composites, which relates to the production process for separating and recycling the paper-plastic composites and is characterized by comprising the steps of: crushing the paper-plastic composite materials by a crusher, hydrothermally degrading the composite materials in a soaking and cleaning tank, removing paper by a paper removing machine so as to separate paper from plastic, mixing the separated paper with water to obtain pulp, filtering and dehydrating the pulp to obtain finished pulp, and preparing the separated plastic into plastic products by a plastic extruding machine. The production process has the following benefits: 1. the process is scientific and reasonable, the paper-plastic composites can be separated and recycled without adding any chemical material or heating, therefore, the process saves time and labor and is safe and efficient; 2. the paper-plastic composites can be separated thoroughly with the recycle rate, paper and plastic can be totally separated and recycled, and the economic benefit is good; 3. water can be recycled completely, and precious water resources can be saved; and 4. the process does not pollute environment.

Description

Technical field: [0001] The invention relates to the technical field of recycling waste materials, and further relates to a production process for separating and recycling paper-plastic composites. Background technique: [0002] With the rapid development of the plastic industry and composite material industry technology, various paper-plastic composites have emerged as the times require, and have been used more and more widely. On the one hand, they have brought great convenience to people's production, and on the other hand A large amount of waste materials are produced, therefore, the recycling of waste paper-plastic composites has become an important part of the recycling of waste materials. At present, the recycling of paper-plastic composites mostly adopts a stirring process, which requires a large amount of water and some chemical raw materials, as well as heating the materials. The recycling rate is low, energy and water resources are wasted, and environmental pollut...

Problems solved by technology

At present, the recycling of paper-plastic composites mostly adopts a stirring process, which requires a large amount of water and some chemical raw materials, as well as heating the materials. The recycling rate is low, energy and water resources are wasted, and environmental pollution is caused. It is urgent to innovate a new Paper-plastic composite separation and recycling production process
