Abstract

The invention provides a slow release type mildew-proof molecular sieve as well as a mildew-proof drying agent and a preparation method thereof. The slow release type mildew-proof molecular sieve is prepared from the following components: a mildew-proof agent, a carrier, a slow releasing agent, a plasticizer and a molecular sieve, wherein the mildew-proof agent is selected from one or two of a fumigation agent and mustard oil. The mildew-proof drying agent is prepared from the following components: clay type minerals, a binding agent and the slow release type mildew-proof molecular sieve. The preparation method of the mildew-proof drying agent comprises the following step of uniformly mixing and stirring the clay type minerals, the binding agent and the slow release type mildew-proof molecular sieve. The mildew-proof drying agent provided by the invention has the advantages of good drying effect, high mildew-proof capability, lasting effect, wide application area, wide application range, convenience for utilization, safety and no toxin and the like.

Description

technical field [0001] The invention relates to a desiccant, in particular to an anti-mildew desiccant comprising a slow-release anti-mildew molecular sieve and a preparation method thereof. Background technique [0002] The role of desiccant: if used in a relatively closed space, it is used to control the humidity of the space where the product is located, so as to protect the product from moisture. Check by yourself during the packaging and transportation of various products such as leather products, textiles, garments, toys, sports equipment, electronic products, and footwear. Generally, the desiccant used has single function, poor moisture absorption effect, short action time, and unsatisfactory use effect. agent, mineral desiccant, fiber desiccant, etc. Depending on the material, the drying capacity of the desiccant will vary. [0003] According to the current situation of common desiccants on the market, it is found that most of the desiccants mainly rely on moistur...
