Abstract
The invention discloses a kieselguhr-based composite material which is characterized by being prepared from the following components: crylic acid, methylcellulose, dodecanol, lauric acid, kieselguhr, peroxosulfuric acid, N,N'-methylene bisacrylamide. According to the kieselguhr-based composite material, the kieselguhr with high moisture releasability, an organic macromolecular material with high hygroscopicity and phase change materials such as dodecanol, lauric acid and thermo-sensitive polymer methylcellulose are combined and matched to prepare a novel composite material with two functions of adjusting the temperature and the humidity. The temperature and humidity adjustment effect of the composite material is good, and the maximum hydroscopicity and moisture desorption ratios are respectively 128 percent and 85 percent.

4.5～5；The consumption of f, h is respectively the 0.5-1.5% of a gross weight.
One of preferably, described raw material is according to percentage by weight a:b:c:d:e=1.8:3:0.5:0.5:4.7；
The consumption of f, h is respectively 1.2 % of a gross weight.
The preparation method of diatomite based composites, its step is as follows:
(1) e at 650-700 DEG C.Constant temperature 0.5h；
(2) by the aqueous solution of appropriate 8mol/L NaOH, it is placed in reaction vessel, a is dissolved in appropriate distilled water as A
Solution, is slowly added to A under ice water bath environment while stirring；
(3) it is stirred vigorously down and is sequentially added into h, e, b, c, d, f and appropriate distilled water；At 75-80 DEG C, heat 5-6h, formed
Take out during solid gel, be placed in 110 DEG C of freeze-day with constant temperature in electric drying oven with forced convection, dried ball mill grinding.
Described solution A concentration is preferably 50% mass fraction.
The invention has the beneficial effects as follows: this invention combines the diatomite of high wet putting, the organic polymer material of high-hygroscopicity
Material, coordinates phase-change material lauryl alcohol, laurate, and temperature sensing polymer methylcellulose to prepare one under certain conditions
What kind was novel has the bifunctional composite of conditioning.The conditioning effect of composite is good, wherein maximum moisture adsorption and releasing
Rate is respectively 128% and 85%.
