Preparation method of compound insect-resistant humidity controlling agent

Abstract

The invention discloses a preparation method of a compound insect-resistant humidity controlling agent. The method comprises the following steps: A) taking sodium chloride and potassium carbonate, respectively dissolving into 150 parts of water, and fully stirring to completely dissolve; B) mixing two solutions prepared in the step A); C) adding water-soluble chitosan to the solution in the step B) to be completely dissolved; D) dissolving water dosage form pyrethrin pesticide into the prepared solution; E) adding copolymer resin of sodium polyacrylate-polyacrylamide to the mixed solution in the step D); F) carrying out thermal treatment on a synthetic product, so as to obtain the dried humidity controlling agent. The compound insect-resistant humidity controlling agent has the advantages that 1) the compound insect-resistant humidity controlling agent is quick in moisture absorption and liberation response speeds, and the relative humidity of a microenvironment can be efficiently and quickly adjusted; 2) regenerated and repeated utilization is very convenient; 3) the pyrethrin belongs to a botanical insecticide, and is free of pollution on environment; 4) the compound insect-resistant humidity controlling agent is simple in production technology and equipment, and easy to industrialize; 5) the material is good in anti-insect effect, and no hazardous substance is generated in the production process.

Description

technical field [0001] The invention relates to a preparation method of a humidity-regulating agent, in particular to a preparation method of an insect-proof compound humidity-regulating agent. Background technique [0002] Relative air humidity is an important parameter to measure the indoor environment. Appropriate humidity plays a very important role in human health and industrial and agricultural production. The annual average relative humidity in the humid areas of southern my country is 70% to 80%, sometimes as high as 95% to 100%, while the relative humidity in the dry period in the northern area is as low as 10%, so humidity adjustment is very necessary. Humidity adjustment methods include mechanical adjustment and non-mechanical adjustment. The machinery for adjusting humidity mainly includes dehumidifiers, humidifiers, and constant humidity air conditioners. The advantage of this method is high efficiency, but the disadvantage is that it consumes a lot of energy t...
