ある。In the above-mentioned adsorbents, activated carbon is black, iron-based adsorbents such as iron hydroxide and iron sulfate are colored substances, and hydrogen sulfide-based The adsorption of zeolites causes them to turn black, which limits their use. Zeolites generally have a low hydrogen sulfide adsorption capacity, and organic acids generally have poor heat resistance, making them unsuitable for kneading into resins.

ることが可能である。A detailed description of the present invention includes aluminum dihydrogen tripolyphosphate, which is a white solid acid with excellent adsorption ability for basic malodorous substances such as ammonia and trimethylamines, and acidic malodorous substances such as hydrogen sulfide and mercaptans. By using a white adsorbent, which is a composite of zinc hydroxide and zinc oxide, which has excellent adsorption ability for gases, it is possible to adsorb acidic and basic gases simultaneously, and both base materials are inorganic solids. They have excellent heat resistance, and the reactivity of both is small, so even if they are mixed in a resin, it is possible to maintain their respective characteristics without reducing their properties.

ルム、脱臭繊維として利用する事も出来る。The resins for each of these adsorbents can be mixed and kneaded at the same time, and the resins used for these include polyethylene, polyvinyl chloride, polypropylene,
Polystyrene, polyethylene terephthalate, polyacrylonitrile, polyacrylate resins, etc. can be advantageously used. The kneaded product can of course be used as a deodorizing agent by granulating or molding it as it is, but it can also be made into a film or fiber and used as a deodorizing film or fiber.
この時、各脱臭剤の添加量は対樹脂０．５％〜２０％が
好ましい。２０％を超えると通常その脱臭剤の量が多過
ぎて、フィルム化、繊維化が困難となる。At this time, the amount of each deodorizing agent added is preferably 0.5% to 20% based on the resin. If it exceeds 20%, the amount of deodorizing agent is usually too large, making it difficult to form into a film or fiber.

特徴がある。In addition, a more porous foam can be obtained by infiltrating liquefied propane, liquefied butane, etc. into a mixture of resin and deodorizing agent and performing post-foaming. Of course, it is used as a deodorizing agent, but because it is lightweight and porous, it has a large surface area, making it even more efficient at deodorizing.

用吸着剤はない。Traditionally, chemical adsorption deodorizers for complex gas systems containing both basic gases such as ammonia and amines and acidic gases such as hydrogen sulfide and mercaptans have been applied to organic compounds that adsorb ammonia and amines. Dual-purpose adsorbents are used that combine acids and inorganic substances (e.g., iron chloride) with iron hydroxide, iron sulfate, zeolite, and activated carbon, which adsorb hydrogen sulfide and mercaptans. There isn't.

ある。In the above-mentioned adsorbents, activated carbon is black, and iron-based adsorbents such as iron hydroxide and iron sulfate are colored substances, which are effective in adsorbing hydrogen sulfide. It turns black and its use is limited. Zeolites generally have a low hydrogen sulfide adsorption capacity, and organic acids generally have poor heat resistance, making them unsuitable for kneading into resins.

ることが可能である。A detailed description of the present invention includes aluminum dihydrogen tripolyphosphate, which is a white solid acid with excellent adsorption ability for basic malodorous substances such as ammonia and trimethylamines, and acidic malodorous substances such as hydrogen sulfide and mercaptans. By using a white adsorbent, which is a composite of zinc hydroxide and zinc oxide, which has an excellent adsorption ability for gases, it is possible to adsorb acidic and basic gases simultaneously, and both materials are inorganic solids. They have excellent heat resistance, and the reactivity of both is low, so even if they are mixed in a resin, it is possible to maintain their respective characteristics without reducing their properties.

Polystyrene, polyethylene terephthalate, polyacrylonitrile, polyacrylate resins, etc. can be advantageously used. The kneaded product can of course be used as a deodorizing agent by granulating or molding it as it is, but it can also be made into a film or fiber and used as a deodorizing film or fiber.
