Abstract

The invention relates to a biological desiccant, which is characterized by comprising the following ingredients including a water retention agent, a water absorbent, an anti-sticking agent and an adsorbent, wherein the water retention agent is konjak flying powder or konjak full powder; the water absorbent is one or a mixture of several materials from anhydrous calcium chloride, magnesium chloride and L-carnitine-L-tartrate; the anti-sticking agent is one or a mixture of several materials from silicon dioxide, white carbon black and talcum powder; the adsorbent is bamboo charcoal or active carbon. The biological desiccant and a preparing method of the biological desiccant have the advantages that the effects of safety, no toxicity and no pollution are achieved; the water absorbing capacity is high; the biological desiccant is suitable for being applied to environments with any humidity; in the environment with T being 25 DEG C and RH being 90 percent, the moisture absorption rate can reach 70 to 200 percent; the prepared desiccant finished product also has the function of odor adsorption; the preparing process is simple; the one-step forming rate of the product is high; the problem of low profits since the konjak flying powder is only used as feed for a long time is solved; the application value of konjak by-products and the diversity of drying agent products are improved.

Description

technical field [0001] The invention relates to the field of desiccants, in particular to a biological desiccant and a preparation method thereof. Background technique [0002] Desiccant is a product with a long history, which is widely used in the storage and transportation of food, medicine, clothing, furniture, wood, handicrafts, electronic appliances, hardware products, etc. At present, several common raw materials are silica gel, live ore, montmorillonite, calcium chloride, quicklime, molecular sieve, etc., which mainly play a moisture-proof effect by absorbing water vapor. The above traditional desiccants have their own disadvantages. For example, quicklime releases heat after absorbing moisture to generate alkaline calcium hydroxide, which has caused many safety accidents in its application; silica gel, molecular sieve, live ore, etc. have low water absorption, and their moisture absorption effect is poor in an environment with low air humidity; calcium chloride It ...
