Embodiment 1

[0015] Embodiment 1: foamed EVA waste material regenerated cloth-making process comprises that foamed EVA waste material 1 is classified and sorted by product source and color sorting in the same source, the foamed EVA that will be sorted and sorted Waste 1 is crushed and mixed into well-dispersed foamed waste pellets. After the composition analysis and confirmation of the foamed waste pellets, the addition and compatibility of EVA raw materials, fillers and coloring materials are carried out according to specific purposes. 5 into the mixture 6, and then through internal mixer 71, open mill 72 mixed melting, calender cloth making machine 73 to make EVA regenerated material cloth 8 with special purpose.

Embodiment 2

[0016] Embodiment 2: The sources of foamed EVA waste materials include slippers, soles, etc., and the slippers and soles, including the defective products discarded in the manufacturing process, are distinguished, and then several commonly used colors are designed as sorting color areas, and then according to the color areas Color sorting is carried out, and individual colors outside the color zone are put into the black zone.

Abstract

The invention relates to a regeneration cloth-manufacturing process for foamed EVA wasted materials. The regeneration cloth-manufacturing process comprises a sorting procedure, a crushing and mixing procedure, a component analysis procedure and a mixed melting cloth-manufacturing procedure. The sorted foamed EVA wasted materials are classified and enter the crushing and mixing procedure; after the foamed EVA wasted materials classified and entering the crushing and mixing procedure are transmitted to a crusher for crushing, the foamed EVA wasted materials enter a dry material mixer to be mixed into foamed waste granules with good dispersion; after components of the foamed waste granules are analyzed and determined in the component analysis procedure, the foamed waste granules are subjected to deficiency supplying and compatibility adding and then form a mixture with a specific purpose; the mixed melting cloth-manufacturing procedure is completed through an internal mixer, an open mill, a transmission mechanism and a calendaring cloth-manufacturing machine; after the mixture is fully mixed and melted into micelles by the internal mixer, the mixture is transmitted to the open mill by the transmission mechanism; the rubber mixed by the open mill is manufactured into regenerated cloth with the specific purpose and a color standard specification by the calendaring cloth-manufacturing machine, and the thickness of the regenerated cloth can reach 30 [mu]m or more according to the purposes.

Description

technical field [0001] The invention relates to a cloth-making process for regenerating foamed EVA waste materials, which belongs to the technical fields of resource regeneration and macromolecules. Background technique [0002] EVA is the abbreviation of ethylene-vinyl acetate copolymer. Generally, the content of vinyl acetate (VA) is 5%-40%. Compared with polyethylene (PE), EVA reduces high crystallinity and improves toughness and impact resistance due to the introduction of vinyl acetate monomer into the molecular chain. , filler compatibility and heat sealing performance, are widely used in foamed shoe materials, functional shed films, packaging molds, hot melt adhesives, wires and cables and toys and other fields. Due to the toughness, foamability and good molding properties of EVA, it has been widely used in mid-to-high-end slippers and shoe soles. EVA plastics are used to make slippers or soles by injection molding foaming process. Injection molding is to heat and m...
