Description
Technical field
The present invention relates to prescription of a kind of building board that can regulate indoor humidity and preparation method thereof, belong to building material field.
Background technology
The humidity adjusting material that building board adopted with moisture control function commonly used at present mainly divides two classes, and a class is to utilize porous mediums such as timber, gypsum, zeolite as humidity adjusting material, and another kind of is to utilize hygroscopic salt as humidity adjusting material.With the building board of porous medium as humidity adjusting material, owing to the moisture in the sheet material mainly is present in the pore with gaseous form, so moisture storage amount is generally less than normal, can only be as a kind of auxiliary moisture control method; With the hygroscopic salt is the building board of humidity adjusting material, because hygroscopic salt is attached directly on the base material such as concrete, become salts solution after the salt moisture absorption, and base materials such as concrete are very limited to the absorption of salts solution, therefore in the higher environment of relative humidity, such building board surface can occur coagulating the water phenomenon, can't be applied to the internal surface of building enclosure.
Summary of the invention
The present invention seeks to propose prescription of a kind of building board that can regulate indoor humidity and preparation method thereof, it is little to solve the same type of material moisture storage amount, the problem of sweating.
The moiety of the building board that can regulate indoor humidity that the present invention proposes is: 1. humidity adjusting material is that macromolecule resin absorbs the gel that forms behind the salts solution, and salts solution wherein is CaCl
2Or LiCl etc. has the solution of moisture-absorption characteristics, and the weight ratio of macromolecule resin and salts solution is 1: 10～20; 2. agglutinate is the air-setting agglutinate, wherein the jointing compound that is adopted is air-setting jointing compound such as cement, gypsum, aggregate is for mainly comprising aggregates such as particle is less, density is lighter yellow sand, perlite, and the volume ratio of jointing compound and aggregate is 1: 1～2 in the agglutinate; On also in the prescription weight ratio of humidity adjusting material and agglutinate be 1: 0.5～1.
The preparation method of above-mentioned building board comprises the steps: that (1) preparation mass percent concentration is 10%～40% hygroscopic salt solution; (2) press macromolecule resin and salts solution 1: 10～20 weight ratio adds an amount of macromolecule resin in salts solution, stir into gel, obtains humidity adjusting material; (3) 1: 1～2 the volume ratio preparation agglutinate of pressing jointing compound and aggregate; (4) press humidity adjusting material and mix humidity adjusting material and agglutinate with the weight ratio of agglutinate 1: 0.5～1, after stirring fast, inject mould, and place temperature in 15～30 ℃ of scopes, in the environment of relative humidity between 70%～80 %, health 48 hours; (5) after health finishes, the demoulding, moulding.
Automatically absorb or discharge water vapour because the effect of hygroscopic salt solution, the present invention can change with ambient moisture, and because salts solution is absorbed by macromolecule resin, therefore water phenomenon with fixed attention all can not appear in inside of the present invention or surface.And moisture storage amount of the present invention is much larger than other moisture control material, therefore as long as it is applied to the building enclosure internal surface, it just can be surplus wet the storing in summer, discharge again to winter, play the effect in " summer wet winter with ", alleviate even removed from fully the humidity load of air-conditioning system greatly, as long as so summer refrigerated water satisfy the requirement of refrigeration duty, water temperature must be too not low, helps the utilization of natural cold sources such as low temperature underground water.
Description of drawings
Accompanying drawing is when envrionment temperature is 24 ℃, the saturated aqueous rate curve of different damping sheet materials.
Embodiment
Embodiment
Preparing a kind of step that can regulate the building board of indoor humidity is: (1) preparation mass percent concentration is 30% CaCl
2Solution; (2) press macromolecule resin: the weight ratio of salts solution=1: 15, in salts solution, add an amount of macromolecule resin, stir into gel, obtain humidity adjusting material; (3) by 1: 1 volume ratio mix cement slurry (water cement ratio is 0.53) and perlite aggregate, stir, obtain agglutinate; (4) mix humidity adjusting material and agglutinate by 1.5: 1 weight ratio, after stirring fast, inject mould, and place temperature in 20 ± 3 ℃ of scopes, in the environment of relative humidity between 70%～80%, health 48 hours; (5) after health finishes, the demoulding, moulding.
The building board that generates is put into different relative humidity environment, measure its saturated aqueous rate under different relative humidity environment, and be linked to be curve, as accompanying drawing 1.
Give the plot of water cut of kahikatea [1] and zeolites conditioning plate [2] in the accompanying drawing 1.Contrast three kinds of materials, as can be seen, saturated aqueous rate of the present invention and rate of curve thereof are all much larger than other two kinds of materials.When ambient relative humidity when 33% changes to 75%, saturated aqueous rate of the present invention changes and is about 385kg/m
3, this shows 1m
3Sheet material can absorb the moisture of 385kg, and its surperficial relative humidity only is changed to 75% from 33%, corresponding, it can guarantee to use room of the present invention indoor humidity also to fluctuate in above-mentioned scope, this shows that the present invention is a kind of good moisture control material.
Explanation is in addition, with LiCl solution replaced C aCl
2Solution; Or adopt other aglite such as plastics sand to replace perlite; Or adopt gypsum as the air-setting jointing compound; Still the moisture control sheet material of suitably adjusting preparation by disclosed each weight ratio of technical scheme by above-mentioned steps also has the similar saturated aqueous rate curve with embodiment, has good moisture control ability.Technical scheme as above-mentioned material is replaced or the adjustment weight ratio forms also belongs to protection domain of the present invention.
