The present invention relates to a board for construction and a method of manufacturing the same,
More specifically, the present invention relates to a building board having high quality and competitive strength, which is excellent in heat insulation, sound absorption and flame retardancy, has a lightweight porous structure, and is manufactured by using perlite (perlite) as a main material. And a method for producing the same.
In general, in order to improve the standard of living, to upgrade the knowledge industry, and to respond to the rapidly changing environment of the information society, it is necessary to enlarge, modernize and functionalize buildings according to the absolute need of the residential space. And it is an inevitable reality.
Therefore, research and efforts have been continued to develop materials that satisfy both lightweight, fireproof, soundproofing, and insulation and insulation of building materials. In response to this demand, porous construction materials are being developed in various fields .
Although the building materials developed so far have been applied to styrofoam, urethane, asbestos, gypsum board or the like, the above-mentioned building materials have problems in that they are not all lightweight, incombustible, soundproofing, insulation and insulation.
First, the Urethane product made of Styrofoam and Urethane is excellent in the warming property to protect the cold air from the outside and to block the outside heat to the outside due to the air inside. On the other hand, in summer, There is a problem in that the room is cooled by the temperature difference inside. However, there is a problem with relatively low heat. In case of fire, toxic gas is spouted and the damage is very high. Urethane foam also has lower ignition rate than styrofoam. There is a problem of being discharged, and the weight is heavy.
On the other hand, asbestos is a mineral containing magnesium and silicon. It is made of soft fibers such as cotton. It has high fire resistance, resistance to friction, resistance to chemicals and electrical insulation. And the like, cause not only diseases such as cancer to humans but also the workability is reduced due to heavy weight when wetted with water. The gypsum board is surely a non-combustible material excellent in heat insulation and warmth, There was a problem that the weight was heavy and it was broken when wet.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems,
The object of the present invention is to provide a high-quality product that is lightweight, non-flammable, sound-absorbing and especially excellent in thermal insulation due to pearlite as a main material to produce a building board corresponding to a building material, So that it is possible to enhance the competitiveness with other companies' products.
In order to solve the technical problems of the present invention as described above, the present invention provides a lightweight and porous pearlite, which comprises a binder which functions or plays a role of enhancing the adhesion of the pearlite, The board is characterized by the construction board.
The binder is characterized by containing calcium sulfate (CaSO 4 .2H 2 O: zircon), potassium sulfate (K 2 SO 4 ), hydroxypropylmethyl cellulose, and heterogeneous mixture.
According to another aspect of the present invention, there is provided a method of manufacturing a building board,
Pearlite; calcium sulfate, potassium sulfate, hydroxypropylmethyl cellulose, and a heterogeneous binder; A curing agent; Preparing the material to prepare water:
Mixing and mixing the pearlite, the binder and the curing agent, which are prepared in the material preparation step, together with water to prepare a kneaded product;
A molding step of filling the kneaded material obtained in the mixing and kneading material preparing step into a mold and molding the same;
A drying step of separating and drying the board cured in the mold; And a control unit.
As described above, the building board using pearlite as a main material according to the present invention is excellent in heat insulation, heat insulation, sound absorption and flame retardancy because it uses pearlite as a main material, has a lightweight porous structure, .
Further, since the building board according to the present invention is environment-friendly, harmless to the human body, and lightweight, it is possible to solve the weak points of the existing building board and to easily work.
Hereinafter, a construction board according to a preferred embodiment of the present invention will be described in detail.
The building board according to the present invention is preferably used as an interior material of a building, and may be formed into a rectangular plate shape as well as various shapes and sizes in addition to a square shape.
The building board according to the present invention is formed by including ① perlite (perlite) as a main material. Here, the main material means that the entire material constituting the board is contained in an amount of 50 wt% or more.
The pearlite is formed by firing the perlite at a temperature of 1,000 to 1,200 DEG C, and is formed into a porous structure having many capillaries by light white porous particles.
The porosity of the pearlite is about 48%, and thus the heat insulating and sound absorbing effect is very excellent.
In particular, pearlite has a specific gravity of 0.15 ~ 0.25, which is a material that can lighten the board for construction.
(2) The building board according to the present invention further comprises pearlite as a main material and a binder and a curing agent.
For example, perlite 1: binder 0.9: water 1: curing agent 0.1.
The binder is a mixture of 45 wt% of calcium sulfate, 22 wt% of potassium sulfate, 7 wt% of hydroxypropylmethyl cellulose, and 26 wt% of heterogeneous silica by stirring at 120 rpm / min.
Among the substances constituting the binder
Calcium sulfate was prepared by preparing 11 wt% sulfuric acid, 65 wt% calcium, 4 wt% salt and 20 wt% dichloride in a low-vacuum stirrer at 200 rpm / min
Potassium sulfate is obtained by stirring 75% by weight of potassium, 5% by weight of glucose and 20% by weight of calcium chloride in a low vacuum at 200 rpm / min.
Hydroxypropyl methylcellulose is obtained by mixing 60% by weight of cellulose, 18% by weight of hydroxylated hydroxypropyl, and 22% by weight of methyl ether with stirring.
Hyungseokgo is obtained by heating raw gypsum at 180 ℃ or more and 36 hours or more.
The binder according to the present invention as described above is an environmentally friendly material which is excellent in adhesiveness, is smooth and easy to form, is low in cost, harmless to human body, and is nonflammable and does not generate harmful substances even in the event of fire.
The curing agent is a material added so as to have an appropriate curing time.
In addition, it is possible to selectively include a coating material as required.
When the above-mentioned paints are mixed to produce a building board according to the present invention, the composition ratio thereof is preferably a ratio of perlite 1: binder 0.9: water 1: curing agent and paint 0.1.
In the binder material, potassium sulfate and hydroxypropylmethylcellulose react chemically with each other to increase the adhesive force of pearlite, and calcium sulfate and bipyongseok have strong adhesive properties when the moisture is evaporated during the drying process, Thereby enhancing the strength.
