AI Technical Summary

Problems solved by technology

However, wood wool cement boards are poorly processable, relatively heavy and susceptible to damage
Likewise, ease of use in building construction is not guaranteed
Therefore, wood wool cement boards are used as exterior wall materials or surface materials of buildings, but are hardly used as building finishing and interior materials

Embodiment 1-3

[0106] The ingredients described in Table 1 below were fed into the mixing chamber and they were premixed with each other for 10 minutes using a strong air flow generated by a compressor installed in the lower part of the mixing chamber. At this time, the amount of each component is described in Table 1 below. The main mixing of ingredients is performed using a low speed ribbon mixer or a high speed pulverizer. Next, the mixed ingredients were pressed using a 500-ton high-pressure hot press to form plates each having a thickness of 20 m / m and a size of 500 mm×800 mm. The formed panels were then allowed to spontaneously cure for 3 days to produce flame retardant panels. The physical properties of the flame retardant board were evaluated according to the above evaluation method, and the results are described in Table 1 below.

Embodiment 4-6

[0116] Fly ash and 7% by weight of the fire retardant described in Table 2 below were fed into the mixer through the metering system, and then mixed with each other in the mixer for 10 minutes. At this point, 5% by weight of lightweighting agent was optionally added to the mixer. Next, spray a portion of the flame retardant curing agent onto the mixture to form a uniformly mixed paste. After adding organic or inorganic fibers with relatively high water absorption into the paste and mixing with the paste for 10 minutes, the remaining flame retardant curing agent and 10% by weight of water were added to the paste containing organic or inorganic fibers. in the paste. At this point, the total content of flame retardant curing agent in the resulting paste was 15% by weight.

[0117] The resulting paste was transferred to an extrusion system and extruded to form noodle-like bodies, and thoroughly dried for 30 minutes in a drying device equipped with a conveyor line. The dried bod...

Embodiment 7-9

[0150] The organic or inorganic fiber (a), fly ash or bottom ash (b) and fire retardant (c) stored in the silo equipped with a metering system are fed into the mixing chamber, using a 30 - Strong air flow from 50 horsepower compressor mixes them with each other. At this time, the non-combustible light weight agent (f) can optionally be fed into the mixing chamber through the silo, and the above-mentioned ingredients are fed into the mixing chamber in the amounts described in Table 4 below.

[0151] Main mixing of these ingredients was performed using a mixer, and a predetermined amount of water was fed into the mixer through a water inlet located at the upper part of the mixer. After feeding the water into the mixer, the flame retardant curing agent (e) is sprayed into the mixing chamber through the nozzle.

[0152] All ingredients fed into the mixing chamber were mixed with each other for 10 minutes to form a paste. The paste was formed into a core material with a thickness...

Abstract

Disclosed is an incombustible composition, an incombustible construction product using the incombustible composition, and a method of producing the incombustible construction product. The incombustible composition includes organic or inorganic fiber, fly ash or bottom ash, fire proofing agent, and curing fire-retardant resin. Additionally, the method includes mixing components, constituting the incombustible composition, with each other, and pressing the incombustible composition using a high pressure hot press, a roller press or an autoclave to give a predetermined shape to the incombustible composition. Therefore, the incombustible composition is advantageous in that it is environmentally- friendly because it contains waste materials, and that it has excellent hardness, strength, and water resistance. Other advantages are that its production costs are relatively low, and that it has excellent incombustibility, depending on the contents of the components constituting the incombustible composition.

Description

technical field [0001] The present invention relates to a non-combustible composition, a non-combustible building product using the non-combustible composition and a preparation method of the non-combustible building product. More specifically, the present invention relates to a noncombustible composition for use as construction finishing and interior materials due to its safety against fire to prevent To prevent the spread of fire and prevent the production of toxic gases from the building finish and interior materials. The present invention also relates to a non-combustible building product using the non-combustible composition and a method for preparing the non-combustible building product. Background technique [0002] So far, medium density fiberboard (MDF), plywood, plaster board, and wood-wool cement board have been used as representative building finishing and interior materials in domestic and foreign building fields. [0003] However, the above construction mater...
