Abstract

The invention discloses a high-moisture-absorption drying agent and a preparation method thereof. The drying agent is prepared from the following ingredients in parts by weight: 20 to 30 parts of zeolite powder, 10 to 18 parts of bentonite, 5 to 12 parts of kieselguhr, 3 to 10 parts of plant starch, 2 to 8 parts of bamboo fiber, 5 to 10 parts of chitosan, 3 to 10 parts of activated aluminum oxide, 2 to 8 parts of pine bark extracts, 3 to 10 parts of liquorice root antioxidants and 1 to 4 parts of nanometer silver ion powder. The preparation method is simple; the prepared drying agent has good moisture absorption performance; meanwhile, the anti-oxidization and antibacterial functions are also realized; the moisture absorption effect of the drying agent is further improved.

Description

technical field [0001] The invention relates to the technical field of desiccant preparation, in particular to a highly hygroscopic desiccant and a preparation method thereof. Background technique [0002] A desiccant is a dehydrating agent that absorbs moisture from the atmosphere. It physically absorbs water molecules in its own structure or chemically absorbs water molecules and changes its chemical structure to become another substance. It is suitable for preventing moisture in instruments, meters, electrical equipment, medicines, food, textiles and other various packaging items. [0003] The desiccant in the prior art has a certain drying effect, but it is easily oxidized during the moisture absorption process, which affects the moisture absorption effect, and the existing desiccant has a short storage time. Contents of the invention [0004] The purpose of the present invention is to provide a highly hygroscopic desiccant and a preparation method thereof, so as to s...
