Abstract

The invention provides a drying agent for removing humidity and odor, which comprises the components by weight percent: 40-75% of ultrahigh molecular weight polyethylene, 20-55% of water absorbent and 5-40% of activated carbon, wherein the molecular weight of the ultrahigh molecular weight polyethylene is 2.5-4 million; and the water absorbent is one or compound of more in water absorption mineral substance, attapulgite clay, active carbon, anhydrous calcium chloride and activated aluminium oxide. The drying agent not only has the performance of removing humidity and odor with high efficiency, but also can be combined with other different functional agents, thus having the effects of absorbing acidic gas and alkaline gas or antibiosis, and the like.

Description

Technical field: [0001] The invention relates to the field of chemical industry, in particular to a desiccant for dehumidification and deodorization and a preparation method thereof. Background technique: [0002] Desiccant is the most commonly used substance in industrial and civil moisture-proof packaging. It achieves its purpose by absorbing water vapor, water and liquid. At present, commonly used desiccant materials include silica gel, molecular sieve, calcium oxide, mineral desiccant, fiber paper, etc., but the dehumidification effect is average and the performance is relatively simple. [0003] For example, the Chinese invention patent with application number 02820634.7 discloses a desiccant comprising a mixture of free fibers and at least one alkali metal or alkaline earth metal halide, optionally containing at least one Or calcium compounds of a different nature from alkaline earth metal halides. However, it is well known that alkali metal halides, such as anhydrou...
