High isolation protection material and preparation method thereof

Abstract

The invention relates to a protective material with high barrier property and a method of preparation of the material. The protective material is composed of an anti-tear layer, an adhesive layer, a high barrier layer, and a seal layer from outer to inner successively, wherein, the high barrier layer can prevent biochemical toxic agent and toxic gas from passing and has the function of corrosion resistance; the seal layer is made of film materials with better thermal stability and mechanical strength, and has the protective effect for high barrier layer; the adhesive layer can mainly increase the binding force between fabric and barrier film, and prevent delamination; the anti-tear layer is made of fabric which is flame retardant or non-flame retardant and can increase the anti-tear function of the composite layer and strength force of all directions of the composite material. The layers are adhered together by adhesive, and then made into protective materials with high barrier property which has multilayer and various protective functions. The protective material has the advantages of excellent anti-tear property, excellent corrosion resistance, and light weight, which can be used for emergency rescue clothing, biochemical protective clothing, risk chemical dealer protective clothing, missile and rocket inflowing protective clothing, etc.

Description

technical field [0001] The invention relates to a protective material, in particular to a high-barrier protective material and a preparation method thereof. Background technique [0002] In the prior art, the double-sided coated tape of butyl rubber or chlorobutyl rubber is usually used as the isolated nuclear, biological and chemical protection material, which mainly relies on its rubber layer or plastic layer to isolate nuclear dust and slow down the biological and chemical agents. permeation of. The material has good protection against persistent poisons such as mustard gas, Viex, and soman, and has good cold resistance, anti-aging, and decontamination resistance. But the disadvantage is that the material is bulky and airtight. When used in hot conditions, the evaporation of sweat is hindered, and the phenomenon of "heat accumulation" will occur, and the human body is prone to overheating and heatstroke; "Condensation" occurs. Commonly used breathable nuclear, biologic...

But the disadvantage is that the material is bulky and airtight. When used in hot conditions, sweat evaporation is hindered, and "heat accumulation" occurs, and the human body is prone to overheating and heatstroke; produce "condensation"

The commonly used breathable nuclear, biological and chemical protective clothing usually uses activated carbon coating method or activated carbon fiber layer to achieve the purpose of nuclear, biological and chemical protection, but the use time of these protective materials is limited, usually not more than 6 to 8 hours

Especially for some chemicals or poisons with strong penetrating ability and corrosion ability, such as unsymmetrical dimethylhydrazine, dinitrogen tetroxide, red smoke nitric acid, etc., these protective materials cannot prevent the entry of poisonous gas and poisonous agents well, and the protective Clothing is too big for protection
