Abstract

The invention provides a reprocessing method and device of an EVA foamed product and a board made through the reprocessing method and device of the EVA foamed product and relates to the field of recycling of the EVA foamed products. The reprocessing method comprises the steps that the EVA foamed product or/and waste of the EVA foamed product is/are heated and fused into an EVA material; the EVA material and an auxiliary material are heated and fused into an auxiliary material-material mixture; and the mixed EVA material and auxiliary material are made to form a designated shape and/or a structure, wherein the auxiliary material is polyethylene or/and polyester fiber or/and polypropylene fiber. In this way, the ineffective product can be fully used as the raw material of the reprocessing method, on the one hand, the demand for recycling the EVA foamed product and/or the waste of the EVA foamed product can be met, and on the other hand, the produced new material or product can meet production and life demands of people. Hence, environmental protection can be facilitated, and huge commercial value is achieved at the same time.

Description

technical field [0001] The invention relates to the field of recovery and reuse of EVA foamed products, in particular to a reprocessing method and equipment for EVA foamed products and the board produced therefrom. Background technique [0002] EVA is made from ethylene-vinyl acetate copolymer (also known as ethylene-vinyl acetate copolymer) by copolymerization of ethylene (E) and vinyl acetate (VA). The English name is: Ethylene Vinyl Acetate, referred to as EVA, E / VAC. Polymerization methods include high-pressure bulk polymerization (for plastics), solution polymerization (PVC processing aid), emulsion polymerization (adhesive), and suspension polymerization. Emulsion polymerization is used for vinyl acetate (VA) content higher than 30%, and high-pressure bulk polymerization is used for low vinyl acetate content. [0003] The performance of EVA has a great relationship with the content of vinyl acetate (VA). When the content of VA increases, its resilience, flexibility,...
