Abstract

The invention provides a coated fabric for a liquid bag. The coated fabric comprises a base fabric, first coatings and second coatings. The base fabric is made by blending sea-island fibers and polyester fibers, a first coating is respectively arranged on both sides of the base fabric, and a second coating is disposed at the end of each first coating. Each first coating material includes the following raw materials: polyvinyl chloride paste resin, plasticizer, paraffin, epoxidized soybean oil, heat stabilizer, ultrafine calcium carbonate, nano calcium carbonate, adhesive, antimold, halogen-free phosphorus flame retardant and ammonium molybdate. Each second coating includes the following materials: polyvinyl chloride paste resin, plasticizer, paraffin, epoxy soybean oil, heat stabilizer, ultrafine calcium carbonate, nano calcium carbonate, antimold, halogen-free phosphorus flame retardant and ammonium molybdate. A preparation method of the coated fabric for the liquid bag is further provided. The coated fabric is free of pollution in the processing process, is an environment-friendly product, has the advantages of good wear resistance, long service life, high acid and alkali corrosion resistance, excellent processing performance and the like, and can be widely used for the liquid bag of various liquids.

Description

technical field [0001] The invention relates to the technical field of coated cloth, in particular to a coated cloth for liquid bags and a preparation method thereof. Background technique [0002] Coated fabric mainly refers to the use of a special process to coat a layer of material with special functions on the basis of the fabric, which adds special functions to the fabric, so it is also called functional coated fabric. [0003] Most of the existing special transport vehicles can only transport goods in one form. When liquid goods need to be transported, most of the special transport vehicles used are liquid tank transport vehicles. Due to the constraints of the tank structure, the items to be transported are single, and the container flexitank has been gradually developed. However, when the existing flexitank is in use, there are still some deficiencies: poor wear resistance, short service life, weak acid and alkali resistance and corrosion resistance.
