Problems solved by technology

The main reason is that although the PVC leather produced by the coating and scraping production process feels soft, it is necessary to add a large amount of flame-retardant plasticizers and powder flame retardants to the PVC formula to meet the flame-retardant requirements of passenger cars, which leads to The viscosity of PVC paste increases, and if the viscosity of PVC paste increases, it will be difficult to apply and scratch, and then the subsequent process cannot be carried out
At the same time, there have been no reports on the formulation and process of PVC composite fabrics produced by the coating and scraping method and meeting the flame-retardant standards for passenger cars.

Abstract

The invention discloses a high-oxygen-index automotive trim PVC (polyvinyl chloride) composite fabric prepared by a blade-coating method and a preparation method thereof. The composite fabric comprises PVC leather, flame-retardant sponge and flame-retardant base cloth, wherein the PVC leather is attached to the flame-retardant sponge and the flame-retardant base cloth through a flame-retardant water-based adhesive; the PVC leather comprises a surface treatment layer, a surface layer, a foaming layer, a bonding layer and a base cloth layer; the surface layer is prepared from the following raw materials of PVC paste resin, a plasticizer, phosphate, tetrabromophthalic anhydride ester, antimony trioxide, magnesium hydroxide, aluminum hydroxide, organic silicon, a heat stabilizer and color paste; the foaming layer is prepared from the following raw materials of PVC paste resin, a plasticizer, phosphate, tetrabromophthalic anhydride ester, antimony trioxide, magnesium hydroxide, aluminum hydroxide, organic silicon, a heat stabilizer, color paste and a foaming agent; and the phosphate ester is a mixture of a plurality of phosphate ester compounds which do not include tricresyl phosphate. The PVC composite fabric prepared by the invention not only has soft hand feeling, but also can meet the flame-retardant requirements of automotive trim, especially a passenger car seat fabric.

Description

technical field [0001] The invention relates to the technical field of artificial leather, in particular to a high oxygen index PVC composite fabric suitable for passenger car seats produced by a coating and scraping method and a preparation method thereof. Background technique [0002] Flame retardancy is a basic requirement for automotive interior materials, and all countries have clear regulations on the flammability of automotive interior materials. The flame retardant requirements for passenger car interior materials are higher. On April 1, 2017, the industry standard JT / T-2016 "Flame Retardant Characteristics of Operating Passenger Car Interior Materials" was officially implemented. On July 1, 2020, GB 38262-2019 " The Combustion Characteristics of Passenger Car Interior Materials was officially implemented, requiring that the horizontal combustion of seat leather materials should not be lower than B, the vertical combustion should be ≤100mm / min, the limiting oxygen in...
