Preparation method of an insect-proof and moth-proof composite humidity-regulating material

Abstract

A preparation method of an insect and moth resistant composite humidity controlling material comprises the following steps: 1, dissolving K2CO3 and NaCl in to prepare an inorganic salt solution; 2, adding an ethanol solution of camphor essential oil into the inorganic salt solution; 3, immersing sodium polyacrylate particles in the solution prepared in step 2; 4, adding konjac glucomannan to deionized water, and stirring to prepare a colloidal solution; 5, slowly adding chloropropylene oxide into the ethanol solution in a dropwise manner to the final concentration of the obtained chloropropylene oxide solution of 4-6wt%; 6, dipping the product obtained in step 3 in the aqueous konjac glucomannan solution obtained in step 3, taking out, uniformly dispersing on a watch glass, uniformly sprinkling the surface of the sodium acrylate particles with the chloropropylene oxide ethanol solution prepared in step 5 through a spray method, allowing the obtained particles to stand, and cross-linking for 2h; and 7, repeating step 6, and drying to obtain a finished product. The finished product has the characteristics of fast moisture absorption and liberation response speed, large wet capacity, long-acting insect and moth resistances, use convenience and the like.

Description

technical field [0001] The invention relates to a preparation method of an insect-proof and moth-proof composite humidity-regulating material, which is aimed at the control of the relative humidity of the micro-environment, and is mainly applicable to the fields of cultural relics protection, book archives storage and storage, etc. Background technique [0002] As a passive means of humidity control, humidity control materials do not need to consume any energy. They have important practical significance for the construction of an energy-saving society, the promotion of sustainable development of the ecological environment, the improvement of indoor air quality, and the improvement of environmental comfort. More and more researchers have begun to conduct various research work on humidity-conditioning materials. Humidity control materials can be roughly divided into the following categories: special silica gel, inorganic salts, inorganic minerals, organic polymer materials, co...

[0003] Invention patent CN201110212362.3 discloses a composite silica gel humidity control agent, which is used to moderately adjust the micro-environment of the museum. Its moisture absorption is only 24% at 60RH%, and only about 40% at 80%. The moisture absorption is not high. , and then the humidity control performance is limited

[0004] Sodium polyacrylate is a kind of super absorbent resin, which has excellent hygroscopic performance, but poor hygroscopic performance, and it is difficult to desorb moisture.

The humidity control effect of inorganic salt humidity control materials is determined by the saturated vapor pressure corresponding to the salt solution, and its stability is good, but the inorganic salt is easy to deliquescence, which is easy to cause pollution
