Embodiment Construction

[0021] The following will be described in detail in conjunction with the embodiments of the present invention.

[0022] The bonding process of EVA material block and EPE pearl cotton block includes the following steps:

[0023] The first step is to prepare EVA material blocks and EPE pearl cotton blocks;

[0024] The EVA is "ethylene-vinyl acetate copolymer" and the rubber-plastic foam material made of it, molecular formula (C2H4)x.(C4H6O2)y; the EPE is expandable polyethylene, also known as pearl cotton;

[0025] In the second step, the EVA material block and the EPE pearl cotton block are cleaned;

[0026] The third step is to dry the EVA material block and the EPE pearl cotton block;

[0027] The fourth step is to attach one end of the EVA material block and the EPE pearl cotton block. After bonding, blow high-temperature hot air through the hot air composite machine to heat. Hot air heating, the heating lasts for 2 minutes, until the other end of the EVA material block ...

Abstract

The invention discloses a technology for bonding an EVA block and an EPE block. The technology comprises following steps: step one, preparing an EVA block and an EPE block; step two, cleaning; step three, drying; and step four, laminating the EVA block and the EPE block, after lamination, blowing the EVA block and the EPE block by high temperature hot wind from a hot wind compounding machine so asto heat the EVA block and the EPE block; during the heating process, clamping the EVA block and the EPE block by hot air rollers, and synchronously heating the EVA block and the EPE block by hot airfor 2 minutes until the EVA block and the EPE block are completely bonded. The provided technology has the advantages that the phenomenon of excessive glue is avoided; the bonding does not need any glue or double faced adhesive tape; the bonding is realized through physical heating, the chemical odor is reduced; no chemical discharge is generated; steps of twice cutting and chemical bonding (adhesive or double faced adhesive tape) are eliminated; the production process and technology are simplified, and thus the production cost is reduced.

Description

technical field [0001] The invention relates to the field of bonding technology, in particular to the bonding technology of EVA material block and EPE pearl cotton block. Background technique [0002] The existing technology is to use double-sided adhesive tape or glue to bond EVA with pearl cotton after cutting. Adhesion to the product, leaving glue marks; 2) The glue or double-sided tape will have peculiar smell; 3) It will increase the processing procedures and processes and increase the cost; 4) It is not conducive to environmental protection requirements. [0003] For this reason, the bonding process of the EVA material block and the EPE pearl cotton block is designed to solve the above problems. Contents of the invention [0004] The present invention provides the bonding process of EVA material block and EPE pearl cotton block for overcoming above deficiency, and the step that comprises has: [0005] The first step is to prepare EVA material blocks and EPE pearl c...
