Problems solved by technology

It can be seen that the comprehensive performance of the protective tent made of this material is obviously insufficient, the material is thick and heavy, and the weather resistance is also poor
[0004] For butyl rubber, the disadvantages are poor processability, elasticity, strength and adhesion
For chloroprene rubber, its disadvantage is that it has obvious crystallization tendency at low temperature, and it is easy to become hard and affect the use.
Moreover, the molding process of the rubber material is complicated and inconvenient to manufacture

Embodiment Construction

[0016] Polyvinylidene chloride (PVDC) is a kind of plastic, in addition to the general properties of plastics, it also has high barrier properties. At present, PVDC has a large number of applications in food packaging. For example, the casings of ham sausage products are currently made of PVDC film. So far, although there are some patent applications, most of them are used in packaging products to achieve the function of moisture-proof and fresh-keeping. For example, the utility model with application number 90210463.2 mainly uses PDVC for paper packaging; the invention with application number 00119751.7 mainly It uses PDVC in liquid packaging; patent No. 03234637.9 mainly uses PDVC as the packaging of medicines.

[0017] However, there is currently no application of textile composites for safety protection, especially for protection against toxic gases. The present invention is described in detail below.

[0018] The textile composite material of the present invention inclu...

Abstract

The invention provides a spinning composite material which comprises a protection layer and a fabric layer; wherein, the protection layer comprises a PVDC layer. The protection layer further comprises one layer or more than one structure layer; the structure layer can be arranged between the fabric layer and the PVDC layer or between the fabric layer and any external side of the PVDC layer. The structure layer comprises a PVDC layer, a fabric layer, a thermal synthesis layer, a framework layer, a camouflage layer, an agglutination layer and a protection layer. By the invention, the fabric composite material has high gas defense performance, physical and mechanical performance and anti-aging and weatherability, and light weight. The invention is especially suitable for making the safety protection of tents, blindages and protection clothes, etc.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a textile composite material. Background technique [0002] Among the textile composite materials used for anti-virus, most of them use isolated anti-virus materials to realize the anti-virus function. Traditional insulating anti-virus materials are mainly polyvinyl chloride (PVC), butyl rubber and neoprene, and these materials have certain shortcomings. Let's explain: [0003] Most of the current nuclear, biological and chemical protection tent textile materials are made of fabrics covered with a PVC layer on the surface. For PVC, in order to achieve a certain anti-penetration performance against poisons, when coating, the material weight of PVC must reach at least 1000g / m 2 . It can be seen that the comprehensive performance of the protective tent made of this material is obviously insufficient, and the material is thick and heavy, and the weather resistance is al...
