Abstract
The present invention discloses a nonflammable lightweight construction interior / exterior composite panel and a method of manufacturing the same. The present invention provides a nonflammable lightweight construction interior and exterior composite panel comprising a frame panel made of a case in which a filler is received and seated, a ceramic formed body which is filled in a state of being seated on the frame panel, Wherein the ceramic formed body comprises 5 to 10 parts by weight of calcium carbide (calcium carbide) and 5 to 10 parts by weight of water, based on 100 parts by weight of the pearlite crushed particles, A chemical reaction agent, and 60 to 65 parts by weight of water glass (sodium silicate) are blended in a binder, and the mixed molding composition is charged in a predetermined mold and compressed and heated to a temperature in the range of 700 to 1,000 ° C. . According to such a constitution, it is possible to obtain excellent mechanical properties and light weight due to porosity, while being excellent in energy efficiency because it is very resistant to heat and humidity and excellent in thermal insulation, and is excellent in fire resistance and gas harmfulness, It is possible to easily produce and provide composite panels for interior and exterior use.
Description
The present invention relates to an interior and exterior composite panel and a method of manufacturing the same. More particularly, the present invention relates to an interior / exterior composite panel and a method of manufacturing the same. More particularly, And a method of manufacturing the same.
Recently, large-scale new buildings such as commercial buildings and residential complexes are becoming more and more super-tall, large-scale, and complex, and they are becoming a landmark of the area. In the case of such an ultra-high-rise large-scale complex structure, it is essential to use a building material to increase energy efficiency as well as to reduce the weight of the envelope system for structural stability and self weight reduction. Accordingly, for example, foam materials having relatively light weight and excellent heat insulating properties such as polystyrene, polyethylene, polypropylene, and polyurethane are mainly used as heat insulators or core materials for sandwich panels.
However, the above-mentioned foamed inner and outer materials are advantageous in economical efficiency and workability, but they are known to have a weak point in heat resistance and flame retardancy such as generation of toxic gas and flame propagation by easily burning in a fire.
On the other hand, inorganic materials such as mineral wool and glass wool are often used as a heat insulating material in a composite panel such as a sandwich panel in order to improve the heat insulation performance of interior / exterior materials of buildings, It is also excellent in heat insulation and shielding property, but there is also a problem that harmful substances such as a lack of air permeability and environmental hormones are discharged.
On the other hand, safety and environment-friendly standards and rules for buildings and residential environments that are safe from various disasters have been strengthened recently. For example, in the case of building exterior wall finishing materials, fireproof materials or semi-fireproof materials are used as finishing materials, The Ministry of Land, Transport and Maritime Affairs has decided that the flame retardant materials that are installed in accordance with the fire prevention standard will be used as finishing materials.
Therefore, according to the trend as described above, recently, functions such as heat insulation and sound absorption have been improved, and as an eco-friendly material which is not harmful to the human body, particularly, as standards such as flame retardancy and incombustibility that can prevent the spread of disasters in the event of a disaster such as fire There is a desperate need for development of a new environmentally friendly interior / exterior material suitable for the environment, and various methods for manufacturing interior / exterior materials capable of satisfying such conditions are suggested. For example, in Korean Patent Registration No. 10-0530015, there are disclosed inorganic materials such as perlite, an expandable inorganic material, diatomaceous earth, loess powder and activated carbon, a liquid inorganic binder such as sodium silicate and alumina sol as a binder, and a thermosetting phenol resin Are mixed and compression-molded at a high temperature.
However, the building interior material disclosed in the above publication has an excellent flame retardancy, but it has disadvantages and drawbacks in that it is heavier and more expensive than a foamed heat insulating material such as polystyrene, polyethylene, polypropylene and polyurethane.
On the other hand, there is a growing demand for environmentally friendly and healthful natural materials such as wood, natural marble, jade, loess, and ceramics as main materials. Such a building interior material is lightweight, There is a disadvantage and a disadvantage that it is difficult to satisfy the required performance of the building material which requires the characteristics such as incombustibility, soundproofness, waterproofness and structural strength, and the price is also high.
SUMMARY OF THE INVENTION The present invention has been made in view of the technical background as described above and it is an object of the present invention to solve the problems of the background art described above, It can not be said to have been publicly known to the general public before.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems and disadvantages of conventional interior and exterior materials for construction as described above, and it is an object of the present invention to provide a non-combustible lightweight And to provide an interior / exterior composite panel.
Another object of the present invention is to provide a non-combustible lightweight construction interior and exterior composite panel which can be formed into various shapes by a simple and easy manufacturing process, thereby improving moldability and economy.

The reason why the average particle size of the pearlite crushed particles is grouped into the first and second pearlite crushed
That is, when the average particle size of the pearlite pulverized particles is too large, the pearlite pulverized particles are mixed and the uniformity of the pores between the respective particles is decreased, so that it is difficult to secure proper mechanical properties due to the reduced density of the formed body. It is difficult to uniformly form the roughness, thereby preventing the function and performance of the interior / exterior material from deteriorating.
In the next step, as shown in FIG. 6, calcium carbonate (calcium carbonate) and water (or salt water) are mixed to produce a chemical reactant 20 (step S-12).

Meanwhile, in the present invention, as is well known, the pearlite is caused by volcanic activity, and volcanic lava or magma flows into atmospheric or surface lakes and is rapidly cooled to 3 to 5% .
Therefore, when the pearlite is pulverized to a predetermined particle size and heat of about 1,000 ° C is applied, the water is gasified and expanded in the softened particles to form innumerable inner pores, and the pearlite is formed into an extremely light pearlite which is 10 to 20 times the original volume.
That is, the pearlite as described above has excellent properties such as light weight, heat insulation, sound absorption, abundance of raw materials, low price, and safe usability. Accordingly, the pearlite pulverized particles are formed as a main component constituting the base of the ceramic formed
