Description
The present invention relates to a decorative panel for building using a stone and a manufacturing method thereof, and more particularly, to a panel using stone powder as a main material and having a high strength and a low expansion shrinkage as compared with a panel using a conventional soil as a main material And a method of manufacturing the same. The present invention also relates to an eco-friendly building material having improved functions such as antimicrobial property, heat insulation property, and nonflammability.
Conventional heat insulation panels used as building materials such as floors, walls, ceilings and the like generally use quicklime as a main material. However, the above-mentioned quicklime has a problem that not only toxic gas is generated in a fire but mold easily occurs due to the water absorption property inherent in quicklime.
In recent years, attempts have been made to make building materials using soil such as loess as a high-function nonflammable environment-friendly material. However, when soil is used as a main material, strength as a building material is not sufficiently manifested, There is a problem that cracks occur during long-term use due to high expansion / contraction ratio of materials in accordance with the environment.
In addition, when a large amount of other synthetic materials such as an adhesive is mixed in order to reinforce these problems, there is a limitation in that the meaning as a highly functional eco-friendly building material is lost.
On the other hand, building materials made of stone such as marble are used as high-grade building materials due to their unique surface gloss and high strength, And difficulty in mining, processing and moving the stone, which is a disadvantage in that a large amount of cost is required for construction and maintenance.
Therefore, when using incombustible environmentally friendly materials, it is possible to realize high strength while minimizing the amount of synthetic materials used, and it has low volume strain and high absorption capacity against external impact, so there is no cracking or cracking even when used for a long time, It was necessary to develop economical building materials by drastically lowering it.
In order to solve the above problems, it is an object of the present invention to provide a nonflammable eco-friendly material which can realize a high strength while minimizing the amount of synthetic materials used, unlike the conventional building materials using earth as a main material.
In addition, since the present invention has low volume strain due to external environment and high absorption capacity against external impact, there is almost no cracking or cracking even when used for a long time, and the cost of mining, processing and transportation is reduced compared to existing stone, And to provide a building material that can be lowered.
Another object of the present invention is to provide a highly functional building material having a high far infrared ray emissivity and having properties such as deodorization, fungus resistance and antimicrobial properties.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a decorative panel for construction comprising a stone powder, a pulp and a gelatin additive. At this time, the abrasive powder may include any one of blast furnace, marble, elvan, granite, and boulder, and the gelatin additive preferably includes glue.
In addition, it is preferable that the heat insulating panel for construction of the present invention contains 80 to 90 wt% of the limestone, 5 to 10 wt% of the pulp and 5 to 15 wt% of the gelatin additive.
Meanwhile, the thermal insulation panel for construction of the present invention comprises a step of mixing slurry, a pulp mixture solution and a gelatin mixture to prepare a slurry mixture; And shaping the slurry mixture followed by hot air drying.
Preferably, the pulp mixture is a mixture of pulp and water in a ratio of 3: 7 to 5: 5 (w / w), and the gelatin mixture is a mixture of gelatin and water in a ratio of 3: 7 to 5: 5 (w / w) is preferably used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, which are intended to illustrate the present invention in a manner that allows a person skilled in the art to easily carry out the invention. The present invention is not limited thereto.
Throughout this specification, when an element is referred to as "including" an element, it is understood that it may include other elements as well, without departing from the other elements unless specifically stated otherwise.
Conventional functional building panels using soil as a main material are not only hard to exhibit sufficient strength as a building material but also have a problem that cracks occur easily during long-term use due to high expansion / contraction ratio of materials due to external environment. Further, when a large amount of an adhesive component is mixed to increase the strength, the content of the soil itself as an environmentally friendly material is lowered.
On the other hand, in the case of a building insulation panel made of a stone such as marble, the strength is high but the absorption power against the external impact is low, and there is a disadvantage that excessive cost for construction and repair is consumed due to difficulty in mining, processing and moving.
In order to solve this problem, the present invention is characterized by using stone powder as a main material of a building panel. Due to the compactness of the particles, the stone can realize high strength without using a large amount of additives, and the volume strain due to the surrounding environment is low, so that cracking does not occur even when used for a long time. In addition, there is no need to maintain the shape of the stone, which can drastically reduce mining, processing and transportation costs.
The powder of the various rocks such as petite, marble, granite, granite, and boulder can be used as the above-mentioned abrasive, and bluffs having various functions such as antimicrobial, antifungal and ultraviolet ray emission can be used.
When the content of the abrasive grains exceeds 90 wt%, the formability of the panel deteriorates. When the content of the abrasive grains is less than 80 wt%, the strength of the panel is lowered, The physical properties are deteriorated.
The above-mentioned stone is easily obtained through various routes such as a mine or a stone processing factory, and it is preferable to carry out a pretreatment process to uniformize particles and remove impurities before being used in a panel. When the particles of the abrasive grains are uneven and contain a large amount of impurities, miscibility and cohesiveness with other components described later may be deteriorated and the physical properties of the panel itself may be lowered.
The pretreatment process may be performed by various methods. However, in one embodiment, the abrasive is removed by removing the impurities by rapid heating of the abrasive supplied through various paths, and the impregnation is performed using a roller mill, a vibrating ball mill, Or the like, to have a uniform particle size.
The rapid heating causes microcracks in the grain boundaries due to the difference in thermal expansion coefficient between the dissimilar elements constituting the stone, thereby separating the impurities and facilitating the subsequent grinding process. The rapid heating may be performed by various methods. Preferably, the rapid heating may be performed by raising the temperature of the abrasive to 700 to 800 ° C. in a short time of 1 to 10 minutes using an electromagnetic wave of 900 MHz to 5 GHz.
Rapidly heated calcareous matter is subjected to hydrothermal treatment in order to remove separated impurities. The hydrothermal treatment is preferably performed at a temperature of 200 to 250 ° C for 20 to 40 hours. The hydrothermal treated stone may have a uniform particle size of 0.1 to 1 mm after drying and pulverization.
Meanwhile, the thermal insulation panel for construction of the present invention is characterized by further comprising pulp and gelatin additives for enhancing the moldability of the stone. The gelatin additive component enhances the cohesive force between the particles of the dust particles and absorbs the external impact. The pulp component sucks the gelatin additive component and acts as a filling material for connecting the particles of the gelatin, Enhances cohesion and further improves cohesion.
As the gelatin additive, various materials including a gelatin ingredient may be used, and preferably glue, which is a natural material, is preferably used. The glue is a substance that solidifies the liquid of an animal such as an animal's skin, tendon, intestines, bones, etc., and is carbonized immediately upon a fire so that a toxic gas generation amount is small and a progress speed of a fire can be lowered.
In addition, the glue can achieve a high adhesive effect even with a small content, and the absorbency against external impact is high due to the specific elasticity of the material, so that cracking due to external impact of the existing stone panel can be prevented.
On the other hand, the glue may be used by adding glycerin in an amount of 1 to 10 parts by weight based on the total weight of the glue to improve the rheological properties of the glue and, in particular, to improve the miscibility with the glue. It is preferable that the glycerin is mixed and introduced into the glue mixture in the preparation step.
The content of the gelatin additive is preferably 5 to 15 wt%, and when the content of the gelatin additive is more than 15 wt%, the panel may bend. When the content of the gelatin additive is less than 5 wt% Molding is difficult to be performed.
When the content of the pulp exceeds 10 wt%, the flame retardancy of the panel and the physical properties of the panel deteriorate. When the pulp content is less than 5 wt%, the content of the pulp is less than 5 wt% And the coagulability of the gelatin additive and the cohesion of the granules are lowered.
Meanwhile, the heat insulating panel for construction of the present invention may be manufactured by mixing slurry, pulp mixture and gelatin mixture to prepare a slurry mixture, and molding the slurry mixture followed by hot air drying.
First, the mixture of pulp and solvent at a ratio of 3: 7 to 5: 5 (w / w), preferably 4: 6, and a mixture of gelatin and solvent at a ratio of 3: 7 to 5: (w / w), preferably in a ratio of 4: 6, is prepared, and then the mixture is mixed with the abrasive powder to prepare a slurry-type mixture. The solvent may be water or an organic solvent which can be removed by drying.
The slurry mixture thus prepared is shaped using a standard frame, and then dried with hot air to dry all of the solvent to finally complete the panel.
Hereinafter, embodiments and experimental examples of the present invention will be described. However, the scope of the present invention is not limited to the following preferred embodiments, and a person skilled in the art can carry out various modifications of the contents described in the present invention within the scope of the present invention.
