Embodiment Construction

[0015] A kind of preparation technology of high plasticity low-temperature hot-melt adhesive of the present embodiment comprises polyester fiber, TPU, PE and EVA,

[0016] Its operation steps are:

[0017] (1) Weaving the polyester fiber net into a base material by a loom;

[0018] (2) Mix and heat PE, EVA, and TPU to liquid glue, and the glue is transported between the two layers of substrates in the equipment by the extruder;

[0019] (3) Through the cold pressing roller, the glue between the base materials is controlled and extruded according to the thickness required by the process to form a plate;

[0020] (4) Then use the glue applicator to scrape the two sides of the board, and apply the melted TPU glue on both sides of the board to make it a high-plasticity low-temperature hot-melt adhesive finished board that can be evenly bonded on both sides.

[0021] Each hot-melt adhesive sheet includes 30-60 parts of polyester fiber, 20-60 parts of TPU, 20-60 parts of PE and 20...

Abstract

The invention discloses a preparation process of a high-plasticity low-temperature hot melt adhesive. The key points of the technical scheme are as follows: the high-plasticity low-temperature hot melt adhesive comprises polyester fibers, TPU, PE and EVA. The preparation process comprises the following operation steps: (1) weaving polyester fiber nets into a base material by adopting a weaving machine; (2) carrying out mixed heating on the PE, EVA and TPU till liquid glue is obtained, and conveying the glue between two layers of base materials in a device by adopting an extruding machine; (3)carrying out controlled extrusion and output on the glue between the base materials by adopting a cold compression roll according to the thickness of the technological requirement, so as to form a plate; and (4) carrying out glue scraping operation on two sides of the plate through a gluing machine, and coating two sides of the plate by adopting the fused TPU, so as to form the high-plasticity low-temperature hot melt adhesive finished product plate capable of realizing adhering of two sides. The hot melt adhesive plate can be operated under normal temperature, and thus harm caused to a personby the process of softening the plate adopting a chemical reagent is avoided.

Description

technical field [0001] The invention relates to a shoe material hot-melt adhesive, more specifically, it relates to a preparation process of a high-plasticity low-temperature hot-melt adhesive. Background technique [0002] The chemical film of the lining of the shoe material needs to be softened by chemical reagents during use, and then the workers carry out subsequent processing to form the lining surface of the shoe material. The operation steps are complicated, and the chemical reagents can be harmful to the human body. cause harm. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a preparation process of high plasticity low temperature hot melt adhesive which is easy to operate, convenient to use and does not cause harm to the human body. [0004] In order to achieve the above object, the present invention provides the following technical scheme: a preparation process of high plasticity ...
