Efficient drying agent prepared from modified guar gum and soybean mixture

Abstract

The invention aims at providing an efficient drying agent prepared from a modified guar gum and soybean mixture. According to the technical scheme for achieving the aim, a preparation method comprises the following steps: dissolving guar gum into water, and stirring at room temperature for 0.5-2 hours; adding an acrylate monomer partially neutralized with alkali, and mixing to be uniform; adding acrylamide and potassium persulfate, and stirring for reaction at 30-70 DEG C for half an hour; after the reaction, performing suction filtration, drying and crushing; adding an auxiliary material, soybeans, and stirring to be uniform; puffing in a puffing machine; grinding and screening to obtain the drying agent.

Description

technical field [0001] The invention relates to the field of desiccants, in particular to a high-efficiency desiccant prepared from a mixture of modified guar gum and soybeans. Background technique [0002] A desiccant is a dehydrating agent that absorbs moisture from the atmosphere. Its drying principle is to physically absorb water molecules in its own structure or chemically absorb and change its chemical structure to become another substance. [0003] The commonly used desiccants include chemical desiccants and physical desiccants. Chemical desiccants dry by combining with water to form hydrates, such as calcium sulfate and calcium chloride, etc. Physical desiccants dry by physically adsorbing water, such as silica gel and activated alumina. However, most of the desiccants have low water absorption capacity, and are easy to reach saturation after absorbing water or become a solution during the moisture absorption process. The most serious thing is that when such desicca...

Problems solved by technology

However, most of the desiccants have low water absorption capacity, and they are easy to reach saturation after absorbing water or become a solution during the moisture absorption process. The most serious thing is that when such desiccants are accidentally eaten by children, they will cause damage to the human body.
