Problems solved by technology

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"
[0003] 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 some of these protective materials do not have waterproof function, which affects the durability of use, some do not have camouflage function, and some do not have The flame retardant function cannot meet the needs of various harsh conditions, and cannot meet the needs of battlefields and special occasions.

Embodiment 1

[0058] Blend spinning of aramid 1313 pure fiber and stainless steel fiber, the stainless steel fiber is 1% of the weight of aramid 1313 pure fiber, then weave, and then use commonly used paint camouflage printing, and then pad containing 40g / L organic fluorine Finishing solution of oil-waterproof finishing agent FX-290, 20g / L nano-silver antibacterial agent and 10g / L DMDHEU, liquid extrusion rate is 40%, baking temperature is 150°C, time is 0.5 minutes, then drying and baking ; That is to make a multifunctional protective fabric layer;

[0059] Microporous polytetrafluoroethylene is made into a barrier layer, and then the multi-functional protective fabric layer and the barrier layer are hot-pressed at 130°C for 1 minute using a powder-dusting glue dot composite process to form a barrier composite layer; the adhesive is polyamide ;

[0060] Set the weight to 100g / m 2 , the specific surface area is 1000m 2 / g of viscose-based activated carbon fiber woven fabric and cotton fa...

Embodiment 2

[0063] The pure spun acrylic fiber and the nylon conductive fiber containing carbon black are blended and spun, the latter is 3% of the weight of the former, and then weaved, and then printed with commonly used paint camouflage, and then pad-rolled containing 120g / L organic fluorine antibacterial Finishing solution of oil and water repellent finishing agent FX-290, 60g / L phenol and 40g / L hexamethylol melamine, the squeeze rate is 80%, the baking temperature is 180°C, the time is 3 minutes, then drying and baking drying; that is, made into a multi-functional protective fabric layer;

[0064] The TPU film is made into a barrier layer, and then the multi-functional protective fabric layer and the barrier layer are hot-pressed at 160°C for 4 minutes using a powder dot composite process to form a barrier composite layer; the adhesive is 904 silicone adhesive (purchased from Shenzhen City Xinwei Chemical Co., Ltd.); before compounding, the multi-functional protective fabric layer is...

Embodiment 3

[0068] Blending sulfonamide and flame-retardant viscose blended fiber with a blending ratio of 50:50 and polyester organic conductive fiber is blended and spun, the latter is 2% of the weight of the former, and then weaves, and then uses high-temperature rapid steaming printing, fast steaming The evaporation conditions are a temperature of 120° C. and a time of 10 seconds. The steaming reduction formula is: caustic soda 40 g / L, sodium hydrosulfite 50 g / L. At the same time, 0.15% paint black is added to reduce the reflection value;

[0069] Then padding contains 100g / L organic fluorine oil-proof and waterproof finishing agent FX-290, 40g / L quaternary ammonium salt octadecyldimethylbenzyl ammonium chloride, 20g / L epoxy resin, 10g / L ethylene glycol Acetal finishing solution, the liquid squeeze rate is 50%, the baking temperature is 160 ° C, the time is 2 minutes, then dried and baked; that is, it is made into a multifunctional protective fabric layer;

[0070] The PES film is ma...

Abstract

The invention relates to a multi-functional vented protective material and a preparation method thereof. The protective material of the invention consists of a multi-functional protective textile layer, a barrier layer and an adsorption layer. The protective material of the invention has a plurality of functions and realizes the harmony, uniform and duration of the functions by organically combining filming, composition and arrangement. The vented NBC protective material prepared by the method of the invention has a plurality of functions, simple process technique, low cost and evident economic and social benefits.

Description

technical field [0001] The invention relates to a multifunctional breathable protective material and a preparation method thereof, in particular to a preparation method of a breathable nuclear, biological and chemical protective material. 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 a...
