Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them.

[0026] An embodiment provided by the invention: 1. A mildew-proof desiccant, the raw materials in the desiccant include anhydrous calcium chloride, molecular sieve, natural plant fiber, activated carbon, isothiazolone, camphor tree extract and citrus extract thing;

[0027] Wherein, the raw material in the desiccant comprises by weight percent composition:

[0028]

[0029] The moisture absorption rate of calcium chloride desiccant can reach 300%, and the moisture absorption rate is 8-15 times that of ordinary desiccants. After completely absorbing moisture, it will not evaporate, thereby improving the water retention capacity of the desiccant, and ensuring that the water will not evaporate due to the increase in temperature after abso...

Abstract

The invention discloses an anti-mildew drying agent and a preparation method thereof, relates to the related field of drying agents, and aims to solve the problems that after a drying agent in the prior art absorbs water and carried out dehumidification, internal moisture is not easy to evaporate, the interior is damp, and mildew is easy to generate due to good water retention. Raw materials in the drying agent comprise anhydrous calcium chloride, a molecular sieve, natural plant fibers, activated carbon, isothiazolinone, a camphor tree extract and a citrus extract. The drying agent is prepared from the following raw materials in percentage by weight: 30.00%-45.00% of anhydrous calcium chloride; 15.00%-25.00% of a molecular sieve; 5.00%-15.00% of natural plant fibers; 13.00%-20.00% of activated carbon; 0.05%-0.4% of isothiazolinone; 2.00%-8.00% of a camphor tree extract; and 5.00%-12.00% of a citrus extract. The desiccant specifically comprises the following raw materials in percentageby weight: 38.00% of anhydrous calcium chloride; 21.00% of a molecular sieve; 8.00% of natural plant fibers; 16.00% of activated carbon; 0.20% of isothiazolinone; 6.40% of a camphor tree extract; and10.40% of a citrus extract.

Description

technical field [0001] The invention relates to the related field of desiccant, in particular to a mildew-proof desiccant and a preparation method thereof. Background technique [0002] Desiccants refer to substances that can remove moisture from wet substances, and are often divided into two categories: the first category is chemical desiccants, such as calcium sulfate and calcium chloride, which are dried by combining with water to form hydrates; the second category is Physical desiccants, such as silica gel and activated alumina, dry by physically adsorbing water. The use of desiccant is to avoid the occurrence of defective products caused by excess moisture. Physical desiccants are suitable for preventing moisture in instruments, meters, electrical equipment, medicines, food, textiles and other various packaging items. Desiccants are also widely used during sea transportation, because the goods are often damp and deteriorated due to high temperature during transportatio...
