Problems solved by technology

The screw extruder is easy to wear and tear, and the performance will be greatly reduced after wear, and it will be expensive to replace the screw and barrel
[0014]2) The PU coating obtained by the roller coating method has different lengths of fluff, uneven flatness, poor scratch resistance, and will be hydrolyzed when exposed to water and alkali. The mechanical strength and tear resistance are not ideal, and high temperature embossing is not possible, and the velvet feel and physical properties are difficult to meet customer requirements

Abstract

The invention discloses a method for producing a PVC imitated cashmere shoe material fabric, which is characterized by comprising a production process of a substrate surface layer, a production process of a substrate bottom layer, a composite foaming process of the substrate surface layer and the substrate bottom layer, a PVC imitated cashmere coating and foaming process and a post treatment process, wherein the composite foaming process of the substrate surface layer and the substrate bottom layer comprises a preheating process of the substrate surface layer and the substrate bottom layer, acomposite process of the substrate surface layer and the substrate bottom layer, and a foaming process of a composite material in turn; and the PVC imitated cashmere coating and foaming process comprises a preparation process of PVC imitated cashmere foaming melt, a process for coating the PVC imitated cashmere foaming melt on a foamed composite substrate discharged in the composite foaming process of the substrate surface layer and the substrate bottom layer, and a foaming process of the PVC imitated cashmere foaming melt in turn. Compared with the prior art, the method has the advantages oflittle disposable investment, high flatness, high post-processing automation degree, good physical performance and environmental protection.

Description

Technical field: [0001] The invention relates to a production method of a plastic composite material. Background technique: [0002] Existing PVC imitation cashmere shoe material fabric is made up of soft PVC base material and one deck PVC yangbuck powder resin coating. Domestic manufacturers all adopt the PU treatment agent roller coating method to produce PVC imitation cashmere shoe material fabrics. Its production process is as follows: [0003] In view of the above characteristics, the existing calendering process of PVC imitation cashmere shoe fabric substrate is as follows: [0004] 1. Production of surface layer and bottom layer of substrate: [0005] It consists of high-speed stirring, low-speed cooling and stirring, melt preparation by single-screw extruder, filtration, four-roll calendering, cooling, and winding. [0006] 2. The existing process flow of PVC imitation cashmere shoe fabric coating is as follows: [0007] Firstly preheat the surface layer and th...
