Abstract

The present invention relates to the technical field of preparation of humidity-controlling materials, and more particularly to a preparation method of a high-temperature resistant composite humidity-controlling material. When indoor humidity is high, capillary condensation may occur in the internal pores of diatomite, so that the humidity is reduced. When the humidity is low, the moisture storedin the pores of the diatomite can be released through the pores, so that the environmental humidity is improved. Calcium lignosulphonate is grafted with acrylamide to obtain a graft copolymer, and thelignosulfonate is adsorbed to various organic or inorganic particles, so that the hydration of free water molecules on the diatomite crystal layer is effectively weakened and blocked. Meanwhile, thecoalescence stability of the system is improved by a large number of anionic groups and non-ionic polar groups. N-vinyl pyrrolidone has the capability of resisting high-temperature degradation and metal salt ion invasion, and meanwhile, the nitrogen atoms and oxygen atoms in the N-vinyl pyrrolidone interact with the oxygen atoms or ammonia atoms in the acrylamide molecules, so that the hydrolysisof the acrylamide can be inhibited. The preparation method has an extensive application prospect.

Description

technical field

[0001] The invention relates to the technical field of preparation of humidity control materials, in particular to a preparation method of high temperature resistant composite humidity control materials. Background technique

[0002] Indoor is the main place of human life. Like temperature, air humidity is also one of the important environmental parameters that affect the comfort of the indoor environment. Appropriate humidity plays an important role in ensuring human health, prolonging the service life of indoor items, ensuring the normal operation of instruments and equipment, and maintaining the sustainable development of the ecological environment. significance.

[0003] At present, people mainly adjust the relative humidity of indoor air through mechanical means such as humidifiers and air conditioners. However, the mechanical method of regulating humidity not only has the disadvantages of high energy consumption, environmental pollution, and ecologica...
