example 1

[0021] Wash the rattan vine, vacuum freeze-dry, grind and disperse, collect the dispersed particles and mix the dispersed particles with a mass fraction of 5% ethanol solution at a mass ratio of 1:10, collect the mixed solution and place it under reflux at 55°C for 3 hours , collect the reflux solution and place it at 45°C for rotary evaporation to 1 / 10 of the original volume, obtain the extract solution and adjust the pH to 3.5 with 1% hydrochloric acid in mass fractions, collect the modified solution and convert the modified solution according to the mass ratio of 1:10. The liquid and petroleum ether were mixed and extracted for 3 times, the extract was collected and the volume ratio was 1:5, the extract was stirred and mixed with n-butanol for 3 times, the n-butanol was recovered by distillation under reduced pressure and the dry matter was collected, ground and pulverized to obtain Modified powder; then weigh 45 parts of deionized water, 10 parts of acrylic acid, 0.5 parts ...

Abstract

The invention relates to a method for preparing an antibacterial mould-proof zeolite-based humidity controlling material and belongs to the technical field of humidity controlling materials. Accordingto the technical scheme of the invention, water soluble alkaloids are extracted and loaded into a high water absorbing gel material, and the alkaloids are uniformly dispersed and pressurized and loaded into inner walls of pores of a zeolite material. Since the inner walls of the pores of the material are in a high pressure environment, the gel material effectively permeates and coats to the surface of the inner walls of pores of the zeolite, the pore structure is effectively reinforced due to effective coating after curing, the moisture-absorbing water-soluble antibacterial enzyme-inhibitoryalkaloids are obtained, effective long-acting bacteria inhibition is realized, and the antibacterial property of the zeolite-based humidity controlling material is improved.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial and mildew-proof zeolite-based humidity-controlling material, which belongs to the technical field of humidity-controlling materials. Background technique [0002] Humidity-regulating materials refer to materials that automatically adjust the relative humidity of the air by sensing changes in the temperature and humidity of the air in the conditioned space by relying on the material’s own moisture absorption and dehumidification properties without the help of any human energy and mechanical equipment. Its notable advantage is that it does not need to consume non-renewable energy such as electricity, has a good ability to automatically adjust the relative humidity of the air and has important development potential, which is of great significance to saving energy, improving environmental comfort, and promoting sustainable development of the ecological environment. . However, this passive ...
