Description

Hardly combustible construction interior material and the manufactury method

The present invention relates to a flame retardant building interior material and a method for manufacturing the same, and more specifically, to produce a building interior material by mixing and pressing a flame retardant mixed with a water repellent and waste fibers, deciduous powder, vermiculite powder, hard coal powder, and resin powder. Fire retardant construction to prevent the damage of life and the spread of fire by toxic gas in case of fire and to make the building interior materials include waterproof function, antibacterial function, insulation function and sound absorption function. It relates to an interior material and a method of manufacturing the same.

In general, building interior materials are made of combustible plastics or wood, which generates various toxic gases during fire and at the same time, spreads the fire, causing a lot of human life and property damage, and using interior materials as a new resource. The cost increased.

In addition, general building interior materials sold at low prices include formalin, toluene, and volatile organic compounds, which emit a large amount of chemicals that are harmful to the human body. People usually have so-called sick house syndrome (rhinitis, atopic dermatitis, hives, asthma, headaches, bronchitis, etc.).

Therefore, in recent years, we have developed functional boards that can fundamentally block the causes of sick house syndrome while preventing many lives and property damages in the event of fire. Insulation, sound absorption, etc. are included.

On the other hand, the prior art is described in Utility Model Registration No. 20-253182 (heat resistant high strength regenerated fiber plywood and its manufacturing method) as follows. First heat treatment at a temperature of 0 ℃ to 500 ℃, and then constitutes the fiber. In order to sufficiently dissolve the thermoplastic fibers, heat them at a temperature of 280 ° C. to 380 ° C. for 2 to 20 minutes using a far-infrared heater, and then, at 300 ° C. to 400 to impart partial thermal decomposition and heat resistance of the fibers. It is prepared by heating at a temperature of < RTI ID = 0.0 > C < / RTI > and compressing it for 2-20 minutes at a pressure between 10 Kg / cm 2 and 30 Kg / cm 2 so as to have a dense structure.

The prior art described above simply produces a single regenerated fiber plywood by heating and compressing the fiber. Since the mixing step of the flame retardant is omitted, the regenerated fiber plywood generates toxic gases in the event of fire and increases human damage. There is a problem of spreading fire.

Another problem is that the regenerated fiber plywood is made of poly-based fibers with no added function, which causes the sickhouse syndrome when the regenerated fiber plywood is installed inside the building, and is also vulnerable to waterproofing and antibacterial properties. Has

At this time, the deciduous leaves are harder and harder plant crops (after harvesting), such as conifers, broadleaf and reed grass, pampas grass, red pepper, eggplant, soybean, and sunflower.

The mixing process (S300) is a process of manufacturing the flame retardant mixture 300 by mixing the pulverized powder 100 and the water repellent solution

Mixed fiber powder 29 ~ 31kg, deciduous powder 29 ~ 31kg, vermiculite powder 18 ~ 20kg, hard coal powder 18 ~ 20kg, resin powder 1 ~ 3kg after mixing the mixed powder to water repellent flame retardant 100kg: 100 ~ 120kg Mix

Mixed fiber powder 40 ~ 58kg, deciduous powder 58 ~ 40kg, resin powder 1 ~ 3kg and then mixed mixed powder to water repellent flame retardant 100kg: 100 ~ 120kg ratio,

It is a process of mixing the mixed powder powder and water-repellent flame retardant in a ratio of 100kg: 100 ~ 120kg after mixing 38 ~ 39kg of the mixed fiber powder, 29 ~ 31kg of vermiculite powder, 29 ~ 31kg of hard coal powder, and 1 ~ 2kg of resin powder.

The water-repellent flame retardant was prepared by dissolving 0.1 kg of the mixture obtained by mixing 0.065 to 0.075 kg of sodium phosphate and 0.025 to 0.035 kg of ammonium phosphate in 1.9 to 2.1 kg of water to obtain a dissolving solution, followed by Korean Industrial Standard KS M1415 ( Liquid sodium silicate) is produced by adding a water repellent to the flame retardant solution by mixing 0.9 ~ 1.1kg of one solution, the mixing ratio of the flame retardant and the water repellent is prepared by mixing a water repellent 0.020 ~ 0.025kg to 1kg flame retardant.

The flame retardant mixture prepared as described above has a heat insulation function and a sound absorption function due to the characteristics of waterproof and antibacterial function and fibers in addition to flame retardancy.

Basic plate forming process (S500) is to supply a flame-retardant mixture 300 by mixing the various powders and flame retardant to the mold 810 and dried for 40 minutes to 60 minutes at 180 ~ 200 ℃ through the dryer 850 do.

At this time, while passing through the microwave, the moisture in the flame retardant mixture 300 is evaporated, and various bacteria are sterilized to form the base plate 500.

Building interior material molding process (S700) is composed of the first and second heat press process and cold press process.

The first hot pressing process by operating the following heat press machine 820 into the base plate 500 to the inner mold 810 and pressurized to a pressure of 6kgf / cm 2 ~ 20kgf / cm 2, at the same time heat press machine 820 It is a process of molding the plate to a predetermined thickness by applying heat for 50 to 70 seconds while maintaining a high heat of 190 ~ 210 ℃ by turning on the heater 830 installed in.

In the second heat press process, the plate subjected to the first heat press process is placed in the mold 810, and then the heat press machine 820 is operated to pressurize at a pressure of 20 kgf / cm 2 to 30 kgf / cm 2 . By heating the heater 830 installed in the heat press machine 820 while applying a heat for 50 to 70 seconds while maintaining a high temperature of 190 ℃ ~ 210 ℃, it is a process of making a plate of a more compact structure.

The cold press process is a process in which the base plate 500 is inserted into the mold 810 and pressurized by the cooling press 840 after the second heat press process, and the plate 500 is inserted into the mold 810. Then, while applying a pressure of 20Kgf / cm 2 ~ 30Kgf / cm 2 with a cooling press 840, while rapidly cooling for 5 to 10 ℃ to 50 ~ 70 seconds through a cooling pipe to complete the plate 500 .

At this time, the ocher layer 930 is formed in 2mm ~ 3mm on one side, or the char layer 950 is formed in 2mm ~ 3mm on one side, or the sheet layer 970 mixed with ocher and charcoal on one surface of the plate 500 unlike the above ) 2mm ~ 3mm.

As described above, the ocher layer 930 formed on the plate 500 generates far infrared rays. The far infrared rays are sterilized and chemically reacted to neutralize formalin, toluene, and volatile organic substances remaining in the room. At the same time, the polluted indoor air is purged and deodorized.

Because of this, the person who is active indoors is promoted metabolism by far-infrared rays generated as described above to prevent sick house syndrome.

Or the char layer 950 formed on the plate 500 is excellent in hygroscopicity to control the humidity in the room, and also removes the odor and formalin, toluene, volatile organic substances (Voc) and the like contained in the indoor air This will prevent people living indoors from building sick house syndrome.

Alternatively, ocher and charcoal are mixed on the plate 500 at a predetermined ratio to form a sheet layer 970. The sheet layer 970 simultaneously shows the characteristics of ocher and charcoal.

Then, the Korean paper 990 is attached to the ocher layer 930 or the char layer 950 or the sheet layer 970 configured as described above to finish the molding of the building interior material 700.

The reason for attaching the Hanji 990 is to prevent the ocher layer 930 or the char layer 950 or the sheet layer 970 forming the building interior material 700 from being separated from the plate 500, and the ocher layer 930 or the char layer. To increase the far-infrared generation of the 950 or the sheet layer 970 and the adsorption of harmful substances and to prevent the generation of toxic gases in the event of fire.

That is, in the past, the interior film (interior film) is attached to the outside because the film hinders the diffusion of far-infrared rays generated in the ocher layer 930 or the char layer 950 or the sheet layer 970 and generates toxic gas from the fire. It is to attach the Hanji 990 without using a film.

In Hanji 990, numerous perforations are formed to emit far-infrared rays generated from loess through the perforations, and harmful substances are absorbed through the perforated charcoal to function more efficiently than when using conventional films.

Building interior material 700 completed as described above can be used in a variety of applications for the interior wall or floor surface of the building, office interior partitions.

In addition, the building interior material 700, when installed and used indoors to prevent the sick house syndrome while exhibiting waterproof and antibacterial function, sound absorption function, heat insulation function.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Will be clear to those who have knowledge of.
