Abstract

The invention relates to a recycling method of a plastic bottle. The recycling method comprises the following steps of step 1, cleaning the recycled plastic bottle, rolling, and cutting the rolled plastic bottle into blocks; step 2, boiling the cut plastic bottle blocks; step 3, putting the cut plastic bottle blocks into a melting extruding machine, and melting the plastic in the melting extrudingmachine; step 4, cooling the melted plastic, and putting into a screw extruding machine. The recycling method has the advantages that the plastic bottle can be conveniently and efficiently separated,and the purity of the recycled plastic is effectively improved; the method is simple, the public benefit and environment-friendly effect are realized, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a method for recycling plastic bottles. Background technique [0002] Plastic bottles with high recycling value now mainly include mineral water bottles and carbonated beverage bottles. The main material of mineral water bottles and carbonated beverage bottles is PET, and the material of the bottle cap is ABS or PP. The ABS cap and PS cap are submerged caps, and PE caps And the PP cover is an unsinkable water cover. [0003] The recycling of waste plastic bottles is a requirement of environmental protection. In the process of recycling plastic bottles, in order to improve the purity of plastic bottles, not only labels, glue and beverage residues must be removed, but also bottle caps must be separated. In the traditional mineral water bottle recycling technology, due to the crude processing equipment and rough processing methods, not only the production efficiency is low, but also the qua...
