Description

Non-fire panel with expansive stone}

The present invention relates to a fire door plate using an expandable mineral.

Most of the materials used as the interior materials of buildings are combustible materials. In the event of a fire, the building interior materials become combustion media, releasing toxic gas and rapidly spreading the fire to adjacent facilities. Therefore, in recent years, a lot of interiors are constructed of fire-resistant materials in general buildings.

Due to the characteristics of the harsh environment applied to the fire-proof material, the material is extremely limited, and at present, ceramics, iron plates, and foamed resins, etc., which can withstand temperatures of 1000 ° C. or higher are mainly used. However, except for the ceramic material among the above materials, the heat resistance is weak, so that the fire door melts when exposed to high temperature for a predetermined time or more, and the ceramic material has good heat resistance, but the strength is weak and the moldability is poor.

Conventionally, the fire door structure has a shape in which a honeycomb spacer is interposed between fireproof plate materials and a plate is connected with a metal material. However, such a structure, when subjected to high heat, the board is severely distorted and a gap is formed, and the fire and high heat are not blocked, and leaks to the outside.

In order to solve the problems of the conventional fire door has been disclosed fireproof door plate using an expandable mineral, but in recent years the interest in health has been increased and the conventional fire door plate has not sufficiently considered the effect on the health of indoor residents, There has been a need for fire door boards that promote health.

The present invention has been made to meet these demands, and an object of the present invention is to provide a fire door door using an expandable mineral that is excellent in thermal insulation and sound absorption and sound insulation, lightweight, non-combustible, improve the health of the human body and prevent environmental pollution There is.

Hereinafter, the present invention will be described in detail.

Fireproof door plate using the expandable mineral produced by the present invention is prepared as follows.

First, vermiculite (pearl vermiculite) and pearlite (pearl stone) are pulverized.

The pulverized vermiculite and pearlite are screened to a particle size of 1 to 5 mm in size, and then the vermiculite and pearlite selected for particle size are rapidly heated to 800 to 1200 ° C. to be peeled and expanded 10 to 15 times. The exfoliation expansion uses an expansion device made of a known expansion furnace.

Next, 30 to 42% by weight of the expanded vermiculite and 40 to 50% by weight of expanded pearlite, 10 to 18% by weight of finely divided ocher, 0.92 to 1.3% by weight of silicate silica, 0.59 to 0.97% by weight of silica gel, Mg-Al sulfonate sodium bicarbonate 0.17 to 0.30% by weight is blended, and then the blended raw material is laminated between two steel sheets to be molded by heating and pressing.

Vermiculite (vermiculite) used in the present invention is a mineral produced by weathering or hydrothermal alteration of biotite, and water molecules are bonded therein, and when heated to a high temperature, bubbles are formed while moisture inside the mineral evaporates. Innumerable pores are formed in and expands up to 20 to 40 times the volume of gemstones.

Pearlite (pearl stone) used in the present invention is a obsidian formed when the volcanic rock is rapidly cooled, the water contained therein evaporates and swells when heated to a high temperature, becomes a fine porous white mineral, acidity is neutral, nutrient content There is little and weeds, seeds, pathogens and pests do not live at all.

Pollution-free pearlite and vermiculite are three-layer structured clouding minerals, which contain moisture between layers, causing dehydration between layers and exfoliating and expanding, thus acting as a myriad of porous thermal insulation soundproof inorganic insulating materials.

Vermiculite is divided into vermiculite gold and vermiculite silver according to its quality. The following Table 1 shows the main components of the vermiculite gold, vermiculite silver, pearl rock, and ocher (kaolin) according to the test report tested by Korea Institute of Construction Materials.

The test was conducted according to KSL 4007-96 and KSE 3808-98. At a measurement temperature of 20.8 ° C., vermiculite gold had a pH of 9.1, vermiculite silver had a pH of 8.1, pearlite had a pH of 6.7, and loess had a pH of 3.8. .

In addition, the emissivity and radiant energy of the vermiculite of the vermiculite were measured by using the FT-IR spectrometer at a measurement temperature of 40 ° C., and compared with the black body. Μm) and vermiculite was 3.62 × 100 W / m ² (40 ° C.).

On the other hand, the present invention is a mixture of the loess with the expandable mineral for the manufacture of fire door plate material, the emissivity of the loess was 0.93 (5 ~ 20 ㎛) and the emission energy of the loess was 4.31 x 100 W / m ² (40 ℃). The present invention is the strength of the plate by the addition of the ocher, the effect of far-infrared radiation beneficial to the human body, the energy saving effect by the heat storage, condensation by the antibacterial effect and humidity control ability to suppress the habitat of harmful insects or bacteria It is characterized by the prevention effect.

The sodium silicate, silica gel and Mg-Al sulfonate sodium binder is an inorganic adhesive.

The physical properties of the sodium silicate are silicate ions, polysilicate ions and silicate ions micelles (Micell) in the colloidal form, SiO ₂ / Na ₂ O in the form of a flow at 550 ~ 700 ℃ generally melt at 1300 ℃.

The temperature for mixing and heating the inorganic adhesive to the expandable mineral is 80 ~ 120 ℃, the pressing force is 180 ~ 220 kg / cm ² . The viscosity of the adhesive is sufficiently low at the heating temperature, and the strength is excellent because the inorganic adhesive is firmly adhered while being sandwiched between the mineral particles by the pressing force.

The ocher from which the exfoliated expanded vermiculite and bio mineral far-infrared is radiated is light and has a fire resistance of 1400 ° C. or more and humidity (RH) of 75% to 1% or less, and condensation is prevented due to a temperature difference between inside and outside. Therefore, by controlling the temperature change in the room to maintain normal body temperature with internal air purification and bio mineral far-infrared rays and vitalize skin health metabolism, the effects of the resonance resonance effect of the human body such as stress relief, digestion promotion, muscle pain relief and waste product promotion Can be obtained.

The fire door board produced by the present invention is mixed with vermiculite and pearlite, a special mineral, a non-toxic non-toxic mineral, and mineral clay, which is yellow clay, which is helpful to the human body. Lightweight non-combustible by making a frame, in the event of a fire as a perfect non-flammable material, as well as acting as a fire, it is effective to improve the health of indoor residents in normal.

Examples will be described below.
