Humidity adjusting material is as a kind of passive damping means, without consuming any energy, for energy conservation social construction, Promote the sustainable development of ecological environment and improves indoor air quality, improves environmental degree of comfort etc. with important practical meaning Justice, thus more and more researchers start to carry out various research work to humidity adjusting material.
The many humidity adjusting materials prepared in the prior art have the following disadvantages: that humidity adjusting material internal gutter is few, cause to inhale and put Wet performance decline；It easily goes mouldy under high humidity environment, generates germ etc.；Particle agglomeration is caused after humidity adjusting material powder moisture absorption, is reduced Humidity.
High-molecular organic material wet volume capacity is big, but its moisture releasing performance relatively lags behind, and mineral material is relative to organic polymer Material wet volume capacity is small.By high-molecular organic material and porosity mineral and natural macromolecular material is compound can be improved in humidity adjusting material Portion's porosity improves moisture releasing performance, and wet volume capacity is big, and has effects that environmental protection.Konjaku is Araeceae herbaceos perennial Stem tuber, widely distributed in China, konjaku glucomannan water imbibition is strong, and swellbility in water is high, and galapectite is a kind of porous The inorganic mineral material of property, surface adsorption property are strong.By high-molecular organic material and konjaku glucomannan and galapectite is compound can To prepare a kind of natural composite humidity controlling agent.
Summary of the invention
The present invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of konjaku glucomannan composite humidity controlling agent Preparation method, increase the wet volume capacity of material with konjaku glucomannan, improve damping using special nano pore structure Rate, and anti-biotic material is imported, solve the problems, such as that humidity adjusting material easily goes mouldy under high humidity environment；It handles, is formed using foaming Multiple porosity humidity adjusting material, it is big to make it have wet volume capacity, and damping response is fast, improves radial migratory pathway, environmental protection, good stability it is excellent Point.
The technical scheme adopted by the invention is that: a kind of preparation method of konjaku glucomannan composite humidity controlling agent, feature It is that steps are as follows:
A, it takes 12-15 parts of sodium hydroxides to be added in 100-120 parts of deionized waters by mass fraction to dissolve, then plus 30 parts Acrylic monomers stirs evenly at being 65-70 DEG C in temperature in aforementioned sodium hydroxide solution；
B, 0.3-0.6 parts of potassium peroxydisulfates are taken by mass fraction, granularity is the galapectite of 200 mesh after 1-5 parts of activation, 1-3 parts Konjaku glucomannan, 0.01-1 parts of nano silver-supported antibacterial powder, 0.3 part of N, N '-methylene-bisacrylamide, 3 parts of urea successively add Enter into the reactor for filling step a acquired solution, reacts 20-30min at being 65-70 DEG C in temperature, obtain sticky solid production Object；
C, 4-5 hours dry at 145-150 DEG C after the step b polymer reacted is cooled to room temperature, pass through urine Element reduces foaming, and obtains porous humidity adjusting material, crushes 2-3min with pulverizer, obtains the humidity adjusting material powder of 100-200 mesh End.
Galapectite activates for roasting 2-2.5 hours through 400 DEG C.
The beneficial effects of the present invention are: 1, the composite Nano Ag-carried antibacterial powder in humidity adjusting material, solves humidity adjusting material and exists The problem of easily going mouldy under high humidity environment has sterilization, antiviral, the effect of bacterium for degrading, organic matter.2, it is foamed using urea, Porosity humidity adjusting material is formed, increases humidity adjusting material inner void, increases the wet volume capacity of humidity adjusting material, its damping is improved and rings Answer speed and radial migratory pathway.3, compared with existing conditioning agent, moisture content of the present invention, wet volume capacity are big, and relative humidity stability is good；System Standby easy, at low cost, effect is good；Environmental protection, it is pollution-free.
Specific embodiment
The present invention overcomes single humidity adjusting material humidity defect, by high-molecular organic material, inorganic mineral material, naturally The advantages of high molecular material and anti-biotic material are combined with each other, and on the one hand absorb all kinds of humidity adjusting materials improves synthetic material itself Wet volume capacity and humidity, while solving the problems, such as that humidity adjusting material easily goes mouldy under high humidity environment, there is sterilization, antiviral, The effect of bacterium for degrading, organic matter；On the other hand it is foamed by urea, forms porosity humidity adjusting material, increased in humidity adjusting material Portion's hole makes it have the advantages of wet volume capacity is big, and damping response is fast, raising radial migratory pathway, environmental protection, good stability.
