Description
Technical field
The humidity-controlling building material that the present invention relates to humidity-controlling building material composition and this humidity-controlling building material composition molding is obtained.
Background technology
In the past, in the wood house of Japan, realized adjustable wet, anti-dew, the mildew resistance of appropriateness by the building materials utilizing cob wall etc. to have adjustable wet.But in recent years, from the view point of raising vibration strength, have a mind to avoid such cob wall, in addition, the public hazards material in order to avoid extraneous air invades indoor and develops height airtightization of buildings.
On the other hand, with the high temperature and humidity exceeded in the past caused by climatic oscillation in recent years, for building materials up to now, the comfortable humidity of indoor maintenance is made to become difficulty.In order to solve this problem, such as, carried out there is the similar porous inorganic material such as zeolite, diatomite of the damping mechanism such as utilization and cob wall in the past to regulate the research of the humidity-controlling building material of the function of humidity as what record in patent documentation 1, patent documentation 2.
On the other hand, the polymkeric substance be made up of organic materials as recorded in patent documentation 3, patent documentation 4 has the feature that moisture uptake is large, rate of moisture absorption is fast of unit weight, but volume change when water adsorption and desorb is large and be difficult to maintain shape etc., is difficult to intensity and the adjustable wet of the appropriateness got both required by humidity-controlling building material.
