PVC/PCA composite coating fabric of sanitary tent and processing technology of PVC/PCA composite coating fabric

Abstract

The invention relates to tent fabric, in particular to PVC / PCA composite coating fabric of a sanitary tent and a processing technology of the PVC / PCA composite coating fabric. The PVC / PCA composite coating fabric of the sanitary tent is prepared from, by weight, 50-100 parts of PVC paste resin, 0-50 parts of copolymer resin, 40-80 parts of an environment-friendly plasticizer, 0-30 parts of a cold-resistance plasticizer, 2-4 parts of an environment-friendly compound stabilizer, 10-30 parts of a flame retardant, 0-4 parts of a mildew preventive, 0-5 parts of a light stabilizer, 0-40 parts of a filler and 0-8 parts of a binder, wherein the copolymer resin is chloroethylene / vinyl acetate / acrylate terpolymer resin (PCA), and the sum of weights of the PVC paste resin and copolymer resin is 100 parts. According to the PVC / PCA composite coating fabric, the use of a large quantity of the low-molecular-weight plasticizer is avoided, and the fabric has excellent wear resistance, folding resistance and low-temperature resistance while the cold-resistance plasticizer is not used or the usage amount of the plasticizer is lowered.

Description

technical field [0001] The invention relates to a tent fabric, in particular to a hygienic tent PVC / PCA composite coated fabric fabric and its processing technology, belonging to the technical field of fabrics. Background technique [0002] Tents have been widely used in national defense, medical disaster relief, scientific research and other fields. When an epidemic or disaster occurs, medical emergency tents are often used in large-scale disaster relief shelters, disaster relief personnel command centers, on-site emergency medical treatment centers, temporary barracks, disaster relief material transfer stations, etc., which are divided into metal skeleton support and non-skeleton inflatable tents. It has the characteristics of easy disassembly and assembly, easy folding, light weight and convenient portability. However, medical emergency tent manufacturers use a variety of fabrics, including ordinary canvas, Oxford cloth, PE woven laminated fabric, polyester fabric / PVC la...

AI Technical Summary

Problems solved by technology

The appearance of the products processed by the three methods is similar, and they are all used in tent manufacturers, but in terms of physical and chemical properties and durability, the bonding method and the coating method are weaker than the coating method

[0004] However, in the existing coating method for producing tent fabrics, due to the unreasonable formula structure, the selection of functional materials is unscientific

As a result, it is difficult to meet high tear, high peel strength; durability, low temperature flex resistance, light aging resistance, flame retardant, environmental protection, antibacterial, anti-pollution and other high comprehensive performance index requirements

To varying degrees, there are shortcomings such as easy peeling of the coating, low-temperature embrittlement and cracking, poor anti-aging performance that makes it difficult to reuse repeatedly, flammability, selection of materials that do not meet environmental protection requirements, and lack of necessary antibacterial and anti-pollution functions.
