Problems solved by technology

The product structure of imported release paper is that the surface of the base paper is coated with a layer of TPX resin material. This material has a natural release function, but its disadvantages are high cost, wasteful production, and high energy consumption. The technology used is electron beam curing. Resin technology has the disadvantages of high cost and high power consumption. The number of times of use is only about 10 times, which is only about 10% of that of polymer artificial leather release paper.
[0003]The traditional production process of leather release paper is to first coat the polymer release layer on the base paper, and then use an embossing machine to emboss the pattern. Heat the paper coated with the release layer to 150-260°C again, and the temperature of the release paper should not be too high, otherwise the release layer will separate from the paper, and the embossing speed can only be controlled at 8-15 meters per minute , therefore, the traditional leather release paper production process wastes time, manpower and energy consumption

Abstract

The invention relates to a high molecular leather release paper producing process capable of effectively improving the production efficiency of leather products. The process comprises the following steps: coating the back surface of body paper with oxidation-resistant liquid glue, drying by using hot air at an instantaneous high temperature, carrying out ultraviolet (UV) curing processing, conveying the processed body paper to a composite embossing unit, pushing multilayer high molecular resin to a high-temperature high-pressure clearance type current reducing spray head through a hot reflux high speed smelting pushing device, uniformly spraying the multilayer high molecular resin on the front surface of the body paper to form half-soakage combination with the body paper, carrying out mechanical embossing at the same time, combining the high molecular material with the body paper to form leather patterns, trimming and rolling to obtain the high molecular leather release paper.

Description

technical field [0001] The invention relates to a production process of polymer leather release paper, which belongs to the field of material processing. technical background [0002] Artificial leather release paper is a special release paper, its coating generally has a concave-convex pattern structure, it is widely used in the artificial leather and synthetic leather industry, as a carrier in the production of artificial leather and synthetic leather, artificial leather release paper Model paper can copy the pattern embossed on it to artificial leather and synthetic leather. my country's required release paper mainly depends on imports. The product structure of imported release paper is that the surface of the base paper is coated with a layer of TPX resin material. This material has a natural release function, but its disadvantages are high cost, wasteful production, and high energy consumption. The technology used is electron beam curing. Resin technology has the di...
