Embodiment 1

[0020] Heat the 0.2-3.0mm thick PVC artificial leather raw material with a base cloth below it to 150°C-200°C and place it on the surface of the plate ceramic blister mold, and stay in the vacuum range of 400mmHg-600mmHg for 2-8 seconds Blister treatment is carried out so that the surface of the PVC artificial leather raw material forms patterns corresponding to the surface of the plate-type ceramic blister mold. After cooling, the PVC artificial leather raw material is formed into leather / leather products for use.

Embodiment 2

[0022] Heat the 0.1-3.0mm thick natural leather + PVC coated raw material to 150°C-200°C and place it on the surface of the roller-type ceramic blister mold. Within the vacuum range of 350mmHg-600mmHg, the roller-type ceramic blister mold Movement at a speed of 10-35 m / min makes the surface of the raw material of natural leather + PVC coating form a pattern corresponding to the surface of the roller-type ceramic blister mold. After cooling, the raw material of natural leather + PVC coating is formed into a leather / Leather products are available for use.

[0023] At the same time, heat the raw material of 0.1-3.0mm thick natural leather + PVC coating to 150°C-200°C and place it on the surface of the plate ceramic suction mold. Stay on the plastic mold for 2-8 seconds to carry out blister treatment, so that the surface of the raw material of natural leather + PVC coating forms a pattern corresponding to the surface of the plate ceramic blister mold. After cooling, the raw mater...

Embodiment 3

[0026] Heat the 0.4-3.0mm thick PU artificial leather raw material to 120°C-170°C and place it on the surface of the roller-type ceramic blister mold. In the vacuum range of 450mmHg-700mmHg, the roller-type ceramic blister mold will be heated at 10-30m / The movement at a speed of 1 minute makes the surface of the PU artificial leather raw material form a pattern corresponding to the surface of the roller-type ceramic blister mold. After cooling, the PU artificial leather raw material is formed into leather / leather products for use.

Abstract

A processing method of vacuum forming for leather products comprises: step 1, making mold; step 2, heating raw materials of the leather products to a specified temperature, putting on surface of the mold, staying in vacuum forming conditions, and forming patterns on surfaces of the raw materials of the leather products, the patterns being corresponding to those on the surface of the mold; and step 3, cooling the raw materials of the leather products, and molding into the leather products for later use, wherein the specified temperature is 150-200 DEG C, the vacuum forming conditions are a vacuum degree range between 350-700 mmHg. According to the invention, the method is simple in technology, molds are convenient to prepare, products can be molded for one time, simulation of finished products is strong, and production efficiency is high.

Description

technical field [0001] The invention relates to a vacuum blister processing method, in particular to a vacuum blister processing method for leather / leather products, and belongs to the technical field of leather / leather product processing. Background technique [0002] With the improvement of living standards, the demand for leather / leather products in the consumer market is increasing. Whether it is used as shoes, clothing, luggage or other purposes, the requirements for the fineness and simulation of the texture and pattern on the surface of leather products are getting higher and higher. The textures and patterns on the surface of existing leather / leather products are usually processed by embossing molds, and the embossing molds usually include steel wheels, silica gel wheels, nickel wheels and the like. The finished product processed by this processing method is limited to ordinary lines, and it is impossible to make exquisite patterns. The embossing effect is general, ...
