Description
Technical field
The present invention relates to a kind of damping material of construction that can automatically regulate indoor humidity.
Background technology
The excess moisture of air, makes people produce humidity, the sense of discomfort such as uncomfortable in chest, brings out the diseases such as sacroiliitis, encourages various moulds virus amount reproductions simultaneously and grows, and affects food-processing and preservation.But air humidity content is too low, can make people produce again allergic, eye xeromycteria, respiratory system resistibility declines, and is unfavorable for healthy.
Current domestic people in the industry can regulate the damping material of construction of indoor humidity automatically in research and development, refer to patent No. ZL200810017527.X, name is called " a kind of damping material of construction that can automatically regulate indoor humidity ", but its automatic humidifying effect is more undesirable, moisture adsorption and releasing speed is slow and moisture adsorption and releasing effect is less obvious.
Summary of the invention
In view of this, technical problem to be solved by this invention is: provide a kind of moisture adsorption and releasing speed sooner and the larger damping material of construction that can automatically regulate indoor humidity of moisture adsorption and releasing amount.
In order to achieve the above object, the present invention adopts following technical scheme to realize:
Can automatically regulate a damping material of construction for indoor humidity, wherein, raw material and the weight part of this material of construction are respectively: the plaster of Paris of 40 parts, 10 parts of vegetable fibres, 8 parts of lithium chloride colloidal sols, 3 parts of calcium sulphate retarders, 11 parts of white portland cement clinkers; The Chemical Composition of above-mentioned plaster of Paris, for taking β semi-hydrated gypsum as main component, does not add the powdered adhesive ramming material of any admixture in advance, and β semi-hydrated gypsum molecular formula is β CaSO
41/2H
2o; Raw material composition and the weight percent content of above-mentioned lithium chloride colloidal sol are: 10% LiCl and 90% polyacrylic High hydrophilous resin colloidal sol, described vegetable fibre is the reed rod powder that reed rod is ground into.
As preferably: also comprise in this raw material of building materials that weight part is the Common Aucklandia Root of 0.1 part and the Lepiota brunneoincarnata powder of 0.1 part.
As preferably: also comprise the slag micro powder of 3 parts of weight parts and the secondary calcium phosphate powder of 0.2 part in this raw material of building materials.
As shown from the above technical solution, the invention has the beneficial effects as follows:
Compared to existing technology, damping successful of the present invention, moisture adsorption and releasing speed is fast.Compared with using the room of this material and not using the room of this material, relative humidity on average reduces by 10% left and right.In actual applications, in the time that indoor relative humidity fluctuates in 30%～60% scope, 1m
2damping sheet material, can make 10m
2the relative humidity in the space of left and right reduces by 16% left and right.In the moisture absorption stage, when the Air permenbility of indoor door and window is 3.9 to 11.72m
3when/h, 1m
2damping sheet material, maximum can reduce about air humidity content 0.60g/kg.And the present invention is cheap, reed rod cost is low, and material easily obtains.Manufacture craft is simple, and production machinery only needs a stirrer and makes the mould of sheet material, is applicable to dissimilar factory process and makes.
And conventionally in the time making moisture absorption material of construction, all adopt straw and straw, commonly in the industry think that the damping effect of the two is the best, and nobody is applied to reed rod in humidity adjusting material, the present invention adopts reed rod powder to mix in the ratio proportioning in the present invention with other raw materials in the present invention as vegetable fibre, make damping effect greatly be better than adopting straw or wheat straw, damping effect is its 2 times of left and right, that is, with the present invention and the ZL200810017527.X of same deal, moisture adsorption and releasing amount of the present invention is all 2 times of left and right of the latter, damping effect is far superior to the latter, and the speed of moisture adsorption and releasing has improved half than the latter, and it is better to whitewash rear texture.Adopt reed rod powder to replace traditional straw or wheat straw is applied in material of construction as vegetable fibre, damping effect is so good, this be do not have completely at the beginning of design thinkable.
