Problems solved by technology

[0003] The flocking cloth is usually bonded to the outer surface of the PVC cloth by glue, but the glue is generally in a glass state after solidification and has no elasticity.
The flocking air bed and inflatable pillow will deform the polyvinyl chloride cloth during the inflation process, so that the glue on the surface of the polyvinyl chloride cloth will be deformed synchronously, which will make the glue easy to occur during the inflation process of the flocking air bed and inflatable pillow The cracking situation makes the glue easy to separate from the PVC cloth and the flocking cloth, which in turn makes the PVC flocking fabric easy to glue and crack, and there is still room for improvement

Abstract

The invention relates to the technical field of spinning. In order to solve the problem that a polyvinyl chloride flocking shell fabric is easy to chip and crack, the invention provides a preparationmethod of a polyvinyl chloride flocking shell fabric and the polyvinyl chloride flocking shell fabric prepared based on the preparation method. The preparation method comprises the following steps: S1, heating polyvinyl chloride flocking glue to be melted; S2, smearing the glue to the outer surface of polyvinyl chloride cloth to form a glue layer; and S3, statically implanting flocks to the glue layer, wherein the polyvinyl chloride flocking glue is prepared from the following components in parts by weight: 80-120 parts of an ethylene-vinyl acetate copolymer, 54-81 parts of thermoplastic polyurethane elastomer rubber, 30-45 parts of an epoxy structural adhesive and 2-3 parts of 2,6-di-tertiary butyl methylphenol. Oxidizing degradation of the rubber is prolonged favorably as a result of the2,6-di-tertiary butyl methylphenol, so that the service life of the glue is prolonged. The 2,6-di-tertiary butyl methylphenol is reacted to the epoxy structural adhesive easily, so that molecules areeasy to entangle, so that the strength of the glue is improved favorably, and therefore, the polyvinyl chloride flocking shell fabric is unlikely to chip and crack.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a polyvinyl chloride flocking fabric and a preparation method thereof. Background technique [0002] Polyvinyl chloride flocking is a high-grade packaging and decoration material formed by electrostatic flocking treatment on polyvinyl chloride. to use. [0003] The flocking cloth is generally bonded to the outer surface of the polyvinyl chloride cloth by glue, but the glue is generally in a glass state after solidification and has no elasticity. The flocking air bed and inflatable pillow will deform the polyvinyl chloride cloth during the inflation process, so that the glue on the surface of the polyvinyl chloride cloth will be deformed synchronously, which will make the glue easy to occur during the inflation process of the flocking air bed and inflatable pillow The situation of cracking makes the glue easy to separate from the polyvinyl chloride cloth and the flocking cloth,...
