The moisture absorption agent comprises a hygroscopic inorganic porous material and sodium polystyrene sulfonate, wherein sodium polystyrene sulfonate is attached to the surface of the hygroscopic inorganic porous material; the hygroscopic inorganic porous material is silica gel with the average pore size which is greater than 4nm. The moisture absorption agent has the characteristics of large moisture absorption capacity and high moisture absorption selectivity and has strong adsorption capacity to moisture. The moisture absorption agent, in which polystyrene sulfonate is attached to the surface of the inorganic porous material, can be obtained through simple stirring, filtrating and drying. The moisture absorption agent can be applied to humidity regulating devices, humidifying devices and ventilating devices.
Description
Technical field
The present invention relates to a kind of formula of hygroscopic agent, belong to chemical industry processing technique field.
Background technology
Hygroscopic agent refer to can be from air any material of absorbing moisture, also claim drier.Conventional solid moisture absorbent has silica gel, aluminium oxide, and molecular sieve etc., these materials have strong compatibility to moisture.The hygroscopic agent scope of application is extensive, can be placed on wardrobe and draw moisture, prevents that clothes is mouldy spoiled, can be placed in automobile except absorbing moisture, can also draw peculiar smell in car, can also be placed in room, absorbs the moisture of air, reduces indoor humidity.
Along with improving constantly that people require indoor environment comfort level, air-conditioning, as the effective means that regulates Indoor environment thermal environment and air ambient, has obtained unprecedented development.But the high energy consumption of air-conditioning is also paid close attention to gradually, and air conditioner energy saving is imperative.The new full recuperation of heat of wind is the effective measures that reduce air conditioning energy consumption.Wherein, rotary type total heat exchanger is one of at present main full heat recovery technology of new wind.The core technology of rotary type total heat exchanger is hygroscopic agent, in order to guarantee indoor air quality, compare with conventional drying agent, be used for the hygroscopic agent of rotary type total heat exchanger except having the feature that hygroscopic capacity is large and adsorption rate is fast, the more important thing is, also tackle steam and there is high adsorptive selectivity, guarantee steam in a hygroscopic agent absorbed air and as much as possible little in the adsorbance of the VOCs gases such as toluene, acetaldehyde to the pollutant component in room air.As core technology, dehydrating breather has not only required high water vapor adsorptive selectivity, also requires harmful components adsorbance as far as possible little.
Traditional hygroscopic agent is difficult to have high selectivity, high hygroscopic capacity simultaneously, restriction in various degree its application in air-conditioning system.Hygroscopic agent water absorption is in the market few, selectively low, and preparation technology is numerous and diverse, and production cost is high, is not suitable for humidity control device, damping device and air interchanger and uses.Therefore develop a kind of novel hygroscopic agent, be applicable to humidity control device, damping device and air interchanger and there is very important market significance.
Inorganic porous material is a kind of novel material, the porous material that adopts special process to be prepared into, and affecting its adsorbing factor has space, aperture, the selection of material, the time of pore-forming, the temperature of pore-forming, the flow velocitys of pore-forming etc., pore size plays critical effect to suction-operated.Poly styrene sulfonate is a kind of macromolecular material, and its molecular weight is huge, can be applicable to the aspects such as reactive emulsifier, water soluble polymer, water treatment agent, semiconductor, has good suction-operated, and steam is had to good adsorption ability.
The present invention be take inorganic porous material and poly styrene sulfonate and is developed a kind of hygroscopic agent as primary raw material, and this hygroscopic agent has that water absorption is large, the selective high feature of moisture absorption, the high adsorption capacity to moisture.By simple stirring, filtration, dryly can obtain poly styrene sulfonate and be attached to the lip-deep hygroscopic agent of inorganic porous material.This hygroscopic agent can be used for humidity control device, damping device and air interchanger.
Summary of the invention
Object of the present invention provides a kind of formula of hygroscopic agent, and this hygroscopic agent has that water absorption is large, the selective high feature of moisture absorption, and the high adsorption capacity to moisture, can be used for humidity control device, damping device and air interchanger.
Object of the present invention is achieved through the following technical solutions: this hygroscopic agent comprises hygroscopicity inorganic porous material, and kayexalate; Kayexalate is attached to the surface of hygroscopicity inorganic porous material; Described hygroscopicity inorganic porous material is that average pore size is silica gel more than 4nm.
Preparation method:
By simple stirring, filtration, dryly can obtain poly styrene sulfonate and be attached to the lip-deep hygroscopic agent of inorganic porous material.
Beneficial effect of the present invention:
A kind of hygroscopic agent of the present invention, has that water absorption is large, a selective high feature of moisture absorption, and the high adsorption capacity to moisture, can be used for humidity control device, damping device and air interchanger.
