Flame-retardant, heat-insulating, burn-through-resistant and metal-droplet-resistant multifunctional composite fabric and preparation method thereof

Abstract

The invention discloses a flame-retardant, heat-insulating, burn-through-resistant and metal-droplet-resistant multifunctional composite fabric and a preparation method thereof. The composite fabric sequentially comprises a flame-retardant heat reflection outer layer, a first heat insulation layer, a second heat insulation layer and a comfortable layer from top to bottom, the flame-retardant heatreflection outer layer is formed by compounding a base cloth layer and a functional film layer, the functional film layer is a high-temperature-resistant polymer film hybridized with heat reflection nanoparticles, the base cloth layer is a blended woven fabric of organic high-temperature-resistant fibers and common flame-retardant fibers or a common flame-retardant woven fabric, the first heat insulation layer is a blended fabric layer of intrinsic flame-retardant fibers and high-heat-shrinkage fibers, the second thermal insulation layer is a phase-change flame-retardant fabric layer, and thecomfortable layer is a viscose-covering polyester wet-permeable woven fabric layer. The composite fabric has multiple functions of flame retardance, metal molten drop resistance, burn-through resistance and heat insulation, and can be directly used for preparing protective clothing for high-temperature operation. The preparation method comprises the following steps: preparing each layer of fabric,and carrying out quilting to obtain the integral composite fabric.

Description

technical field [0001] The invention relates to the technical field of safety thermal protection fabrics, in particular to a flame-retardant, heat-insulating, burn-through, and metal droplet-resistant multifunctional composite fabric and a preparation method thereof. Background technique [0002] Personnel in high-temperature industries such as fire fighting, petrochemical, and industrial furnaces need to wear protective clothing with flame-retardant, fire-resistant and burn-through properties. This type of clothing requires a high heat reflectivity on the surface; It should have a certain ability to resist the impact of metal droplets to protect the safety of the operator. [0003] Generally speaking, the fabrics used for high-temperature-resistant and flame-retardant clothing are either woven from high-temperature-resistant organic fibers, or the fabrics are treated with flame retardants to obtain flame-retardant functional fabrics. However, the fabrics prepared by these ...

Problems solved by technology

However, the fabrics prepared by these two methods only have certain flame retardancy, are not heat-insulating, and cannot realize their anti-metal droplet impact function.

[0004] Therefore, in order to improve the performance of the fabric against molten metal dripping, the existing welding and smelting protective clothing is made of multi-fiber blended fabrics or materials such as filming or coating aluminum on fabrics and leather to protect the human body from molten metal, sparks, etc. and high-temperature burns, such as the patent CN 10760751B discloses a flame-retardant, fire-proof, and metal droplet-proof aramid fabric, including an outer layer, a middle heat insulation layer, and an inner layer, wherein the outer layer is made of meta-aramid fiber, acrylic chlor
