Problems solved by technology

This product (Prior Art 2) simply sprays activated carbon powder on fabrics such as non-woven fabrics and then pressurizes them. Therefore, when wearing this product for activities, there is a problem that the activated carbon falls off from the fabric, and a part of the activated carbon is lost during washing. , so there is still the problem of not being able to reuse
[0013] For this product, because the activated carbon is in powder form, it is bonded to the fabric with an adhesive. In this case, the activated carbon is buried in the adhesive, so that the activated carbon cannot perform the adsorption function, especially the adhesive isolating the fabric. As a result, the fabric loses its breathability, so activated carbon has to be simply sprayed on the fabric

Embodiment Construction

[0084] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0085] Such as figure 1 As shown, the adsorbent for nuclear, biological and chemical agents according to the embodiment of the present invention includes powdered activated carbon 11, matrix 12, solvent S and microparticle filler A.

[0086] The matrix 12 is a mixed activated carbon 11 and is composed of a gel or colloid of a thermosetting or thermoplastic material that hardens from a liquid state to a solid state, and after hardening provides a sheet-shaped adsorption layer described later. For example, the matrix 12 is also excellent in adhesion to fibers under low temperature hardening conditions, and has excellent adhesion to fibers, and imparts elasticity to the adsorption layer, and then environmental-friendly water-based polyurethane can be used alone to improve The durability of the adsorption filter, or according to other requi...

Abstract

The invention relates to an adsorbent for a nuclear biochemical agent, a fabric and a manufacturing process. The adsorbent includes a matrix, powdered activated carbon, a solvent and a soluble microparticle filling material; the powdered activated carbon is mixed in the matrix and adsorbs toxic substances; the solvent is mixed in the matrix and mixed with the powdered activated carbon in the matrix; and the soluble microparticle filling material consists of multiple microparticles mixed with the solvent in the matrix and adhering to the powdered activated carbon, and can be extracted and removed from the hardened matrix, so that pores formed by bubble-shaped holes can be provided for the matrix. The pores can be provided for the outer peripheral face of the activated carbon through the microparticle filling material.

Description

technical field [0001] The present invention relates to an adsorbent for nuclear, biological and chemical agents, an adsorption filter for toxic substances, protective clothing and its manufacturing process, and more specifically relates to uniform formation of activated carbon to improve the adsorption performance of substances with or without substances, and does not cause the activated carbon to fall off during washing , and then the adsorbent for nuclear, biological and chemical agents, the adsorption filter for toxic substances, protective clothing and its manufacturing process that can be reused after washing. Background technique [0002] In general, with the development of a large number of lethal weapons and the increase of countries possessing them in modern warfare, products capable of protecting human bodies or equipment are being demanded. Among the weapons of mass destruction, the production cost of chemical weapons is low, and because of the miniaturized manuf...
