Problems solved by technology

[0007] The main purpose of the present invention is to provide a synthetic leather manufacturing method in which the base material and the skin are molded at one time. It utilizes two sets of injection mixing devices to separately manufacture a base material and a skin layer of a PU plastic foam layer at the same time, and make the two All of them are laminated in a half-reacte

Example Embodiment

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Please refer to figure 1 Shown, the synthetic leather manufacturing method that the base material that the present invention proposes and dough one-shot molding comprises the following steps:

[0045] A base cloth 10 is conveyed to a predetermined direction, and the base cloth 10 is made of cloth, non-woven fabric, microfiber or the like, and it is conveyed by the conveying wheel 11 and the roller 431, the upper roller 71, the lower roller 431 positioned at its rear side The rollers 72 and the take-up device 80 are jointly driven in a synchronous manner, so that they are transported forward along the table surface of a workbench 12 .

[0046] Take a first injection mixing device 20 and place it above the base cloth 10, inject and pour the PU resin and foaming material on the surface of the base cloth 10 to form a base material...

Abstract

A synthetic leather manufacturing method in which a base material and a skin are formed at one time, which utilizes two sets of injection mixing devices to manufacture a PU plastic foam layer and a skin layer at the same time, and make both of them half-reacted but not completely hardened. In order to achieve the effect of one-time molding, the present invention overcomes the shortcomings of the known technology that the base material and the dough must be manufactured separately, and the space for storage and accumulation of materials is wasted, thereby shortening the manufacturing process and saving plant equipment. And manpower, electricity and material resources, as well as reducing production costs, no air, water pollution, and has the advantages of a wider range of uses.

Description

technical field [0001] The invention relates to a synthetic leather manufacturing method, in particular to a method of injecting and pouring foamed plastic material on a base cloth by using an injection machine, and then injecting and pouring unfoamed plastic material on a release form by using another injection machine. A synthetic leather manufacturing method that forms a skin on paper and presses the substrate and the skin in a semi-reactive state that has not yet fully hardened. Background technique [0002] At present, the known manufacturing method of artificial synthetic leather must first produce a base material, which usually contains various raw materials and solvents in one or several dipping tanks, and guides the base cloth to pass through the dipping tanks impregnation of the material, and then introduce the base cloth into a water tank to make the surface gel and solidify, and then use electric heating drying equipment to dry it to form a synthetic leather base...
