Abstract
The invention provides a producing method of PVC artificial leather based on a calendering scrape coating method. The producing method comprises the steps that first, a bottom layer to be foamed is subjected to calendering, and an bottom film is obtained; then, a scrape coating machine coats prepared scrape paint on the bottom film in a scrape manner, and the bottom film with surface slurry is obtained; finally woven cloth and the bottom film with the surface slurry are subjected to hot-pressing and composition by a hot-pressing foaming machine; and foaming of the bottom layer, plasticization of a surface layer and embossing are accomplished during the hot-pressing and the composition. Compared with the conventional process of calendering the bottom layer, calendaring the surface layer and then compositing, the surface layer calendering course is removed; when the PVC synthetic leathers with the same style and quality are produced, the productive capacity can be improved by about 30%; the energy consumption is reduced by about 30%; during the hot-pressing and the composition, the plasticization of the surface layer, the foaming of the bottom layer and the embossing are combined into one procedure; the energy consumption is reduced; and the production efficiency is improved. With the adoption of a surface scrape coating method, a used scrape paint formula is innovated, and the PVC artificial leather with various functions can be produced.
Description
Technical field
The invention belongs to PVC artificial leather technical field, particularly a kind of PVC artificial leather spread coated paint and adopt this spread coated paint to prepare the method for PVC artificial leather.
Background technology
Artificial leather and synthetic leather are histological structure and the serviceability of simulation leather, and can be used as the composite of leather substitute.Usually with the lamina reticularis of woven fabric and non-weaving cloth simulation leather, with the grain layer of micropore polymeric coating layer simulation leather, resulting artificial leather is all more similar with leather to the synthetic leather positive and negative, is widely used in making footwear, boots, case and bag and ball etc.
In common sorting technique, artificial leather be with woven fabric as base cloth, apply the simulated leather material that high molecule size is made, most with polyvinyl chloride (PVC) as coating agent, be commonly called as " PVC " artificial leather.
In China, artificial leather the earliest is the nitrocellulose varnished cloth that the Shanghai varnished cloth producers' cooperative of the forties produces, and develops artificial leather about Shanghai Plastic goods one factory in 1958 greatly, has also just formally opened the prelude of Chinese people fabricate-leather development.So far, formed thousands of manufacturing enterprises in the inland of China, artificial leather has been widely used in the thousands of kinds such as the lamp box advertisement, canopy lid, automobile of clothes, shoes and hats gloves, case and bag, family's living furniture, culture and sports, industrial or agricultural and the communications and transportation of people's daily life.
Approximately nineteen thirty, polyvinyl chloride (PVC) is in the U.S., German Industrial, and approximately 10 years evenings, polyvinyl chloride (PVC) is just at Japanese industry.Japan had developed the Carlender machine in 1958, made PVC foamed plastic leather.PVC artificial leather epithelium is tough and tensile, uses a lot at vehicle, suitcase, clad material.Again in default of gas permeability and water vapor permeability, so be not suitable for doing footwear.But because PVC is cheap, so still generally use.
Artificial leather is kilogram according to the national standard Statistical Criteria, and according to square metre being unit, conversion relation is 0.66 kilogram/square metre of artificial polyvinyl chloride leather product; 0.5 kilogram/square metre of Synthetic Leather.To 316 artificial leather synthetic leather enterprise production statistics more than the scale, 2010 annual Chinese people fabricate-leather synthetic leather total outputs are 218.9 ten thousand tons according to State Statistics Bureau, and wherein artificial leather accounts for 42%, its production rank the first in the world.
At present, polyvinyl chloride (PVC) production technology has following several, and technical characterictic is as follows respectively:
(1) direct knife coating: the technological process of production is as follows:
Base fabric → plastisol primary coat → dry → offset bright dipping → cooling → plastisol face to be coated with → embossing → cooling → finished product.
(2) directly knife coating foaming: the technological process of production is as follows:
Base fabric → dipping or primary coat → dry → be coated with foaming layer → plasticizing to foam → cool off → be coated with surface layer → oven dry → cooling → post processing.
(3) blade coating film applicator coating foaming: the technological process of production is as follows:
Base fabric → be coated with foaming layer → plasticizing → cooling → pad pasting → foaming → embossing → cool off → batch.
(4) release liners transfer method: the technological process of production is as follows:
Raw material metering → high-speed stirred → three roller grinding → release liners uncoilings → be coated with surface layer → plastify → be coated with foaming layer → be coated with adhesive layer → end fits → plastifies → peel off → bass batches → check of bass covering with paint → bundling.
(5) calendered layer is legal: the technological process of production is as follows:
At first roll foamed bottom layer and obtain bottom film, then the surface layer that do not foam of calendering obtains the surface layer film, at last with base fabric, bottom film, that surface layer film three utilizes the hot-pressing and foaming machine to carry out is compound, finishes foaming and the embossing of bottom when hot pressing is compound.
At present, for the production of PVC artificial leather, ubiquity the higher and lower problem of production efficiency of energy consumption, and how to save energy and reduce the cost also is main target and the power that present enterprise carries out technical research.
