Abstract

The invention discloses a production method of a gas-permeable PVC composite material. The preparation method comprises the following steps: uniformly stirring and mixing raw materials at a high speed, carrying out internal mixing and open mixing, calendering, cooling, drawing to obtain a rolled PVC film, and finally embossing and bonding to obtain the gas-permeable PVC composite material. According to the invention, based on the problem of fiber structure deformation during 3D fabric pattern embossing, the temperature is circularly reduced through an embossing machine and a fabric contact heating wheel, so that the fabric is prevented from being deformed due to high-temperature heating; in order to reduce the total thickness of the composite material, a thin PVC composite material can beobtained by adjusting the gap between embossing wheels and the temperature of embossing points; and based on the problem of unclear surface patterns in the prior art, the total thickness and the clearpatterns of the PVC composite material can be ensured by precisely controlling the temperature of the embossing points.

Description

technical field [0001] The invention belongs to the production field of PVC composite materials, and in particular relates to a production method of breathable PVC composite materials. Background technique [0002] The main component of PVC is polyvinyl chloride, which is light yellow, translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. And lower than polypropylene, there will be whitening at the inflection. Common products: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. Polyvinyl chloride (PVC) was industrialized in the United States and Germany in about 1930, and it was industrializ...
