Abstract

The invention relates to a drying agent and in particular relates to a preparation method of a charcoal particle drying agent. The preparation method of the charcoal particle drying agent comprises the following steps: uniformly mixing the raw materials; carrying out electronic radiation crosslinking treatment; and processing the raw materials into particles, strips or sheets. The raw materials comprise the following components in parts by weight: 60-80 parts of bamboo charcoal powder, 15-25 parts of bentonite, 10-13 parts of calcium chloride, 9-12 parts of magnesium sulfate, 5-8 parts of starch, 4-9 parts of attapulgite ore, 6-11 parts of hard gypsum ore, 1-3 parts of bamboo leaf oil, 3-7 parts of adhesive liquid, 0.1-0.5 part of capraldehyde, 0.2-0.4 part of linalool, 0.02-0.06 part of thymol, 0.6-0.9 part of glyceryl triabietate and 5-8 parts of a moisture absorption additive. The moisture absorption additive is selected from polyvinyl alcohol fiber, polyoxyethylene fiber, alginate fiber and mulberry silk; the adhesive liquid comprises phthalic anhydride, furfuryl alcohol, triethylene glycol, glutaric acid, butantriol, zinc oxide powder, magnesium oxide, chloroprene rubber, elastic rubber, softening oil, dimethyl carbonate, benzoyl peroxide, acetic ether, an emulgator, flour, nano-silver, a fire retardant, methylcellulose and deionized water. The drying agent is high in drying performance and fresh and natural in smell, and has a good deodorizing effect.

Description

technical field [0001] The invention relates to a preparation method of a desiccant, in particular to a preparation method of a carbon particle desiccant. [0002] Background technique [0003] There are many types of desiccants, and each has its own characteristics. How to improve the drying efficiency of the desiccant, prolong the service life of the desiccant, and reduce environmental pollution are also subjects that have been studied. [0004] CN102327729B (2013-4-17) discloses a bar-shaped container desiccant, the key point of its technical scheme is that the bar-shaped container desiccant is composed of dolomite attapulgite clay, sulfuric acid, high-viscosity attapulgite clay powder, chlorinated Calcium and super absorbent resin composition. The production method of the bar-shaped container desiccant: input the ingredients of the bar-shaped container desiccant into the mixer for mixing and stirring, and then seal and pack it into the bar-shaped container desiccant. ...
