Abstract

The invention discloses a flame-retardant, antitoxic and anti-chemical fabric and a manufacturing method thereof. The fabric sequentially comprises an outer layer, a middle layer and an inner layer from the outside to the inside, and the layers are sequentially connected; the outer layer adopts a flame-retardant polyolefin film; the inner layer adopts any one of an ePTFE film, a flame-retardant TPU film, a flame-retardant TPEE film, a flame-retardant PVC film, a flame-retardant polyolefin film, a flame-retardant PU coating, a flame-retardant PVC coating, a PVDC coating and a PVDF coating; andthe middle layer is composed of a flame-retardant fiber fabric and a polyhaloolefin film. The fabric has the advantages of excellent hazardous chemical substance penetration resistance, good anti-toxicity, good flame retardancy and light weight. The overall thickness of the fabric is 1.0-2.5 mm, the gram weight is less than 550 g / m<2>, the fabric can resist mustard gas penetration for 72 h or more, can resist chemical substance penetration for 8 h or more, and has an afterflame time of 10 s or less, a smoldering time of 10 s or less and a damaged length of 100 mm or less. The method is simple,and is easy to implement.

Description

technical field [0001] The invention relates to the field of chemical protective fabrics, in particular to a flame-retardant, anti-virus and chemical-resistant fabric and a manufacturing method thereof. Background technique [0002] Chemical protective clothing is the main equipment to protect the life safety of on-site emergency rescue personnel when dealing with hazardous chemical accidents, and its core component is chemical protective fabric. Moreover, the phenomenon of hazardous chemical accidents is often accompanied by some flash and deflagration phenomena, so the flame retardancy of chemical protective fabrics is also required. In addition, violent terrorist attacks at home and abroad have emerged one after another in recent years, and the security situation is not optimistic. Therefore, it is especially necessary to endow the chemical protective fabric with anti-virus function. [0003] Traditional chemical protection fabrics are formed by coating rubber materials...
