Problems solved by technology

Among the current flame retardants of polymer materials, metal oxides and hydroxides are cheap and non-toxic, but they are not compatible with materials, which will reduce the thermodynamic properties of materials
Although halogenated flame retardants, especially bromine-containing flame retardants, have good flame retardant effects, they have serious disadvantages such as large smoke generation, corrosive and toxic gases, and molten droplets when they burn.

Abstract

The invention discloses a flame retardant finishing method of a fleece polyester fabric for the seats in high-speed trains. The finishing method comprises the following steps: soaking fleece polyester fabric in a silica-alumina composite sol according to a weight ration of 1:10-20, baking, painting a P-S flame retardant on the fabric, wherein the content of the P-S flame retardant is 200 to 280 g / L, and baking. The silica-alumina composite sol is prepared by mixing silica sol with a mass concentration of 1 to 5% and alumina sol with a mass concentration of 0.5 to 5% according to a mole ratio of 1: 0.8-1.2. The processed fleece polyester fabric has a good flame retardant performance, and at the same time the fleece surface is not influenced.

Description

technical field [0001] The invention belongs to the flame-retardant field of seat fabrics for high-speed rail and motor vehicles, and mainly relates to a method for flame-retardant fleece polyester seat fabrics for high-speed rail and motor vehicles. Background technique [0002] For more than half a century, high-speed trains in Japan, Germany, France and many other countries have been developing rapidly. Fast, comfortable and high-safety high-speed trains have promoted the rapid development of social economy in various countries. In order to cooperate with the national Olympic strategy, my country has also started to develop high-speed rail and bullet trains since the beginning of this century. After nearly 10 years of rapid development, it has achieved world-renowned achievements. The process of continuous improvement of comfort and continuous enhancement of reliability to meet the needs of social and economic development. [0003] Interior textiles are one of the most cr...
