INCOMBUSTIBILITY COMPOSITION FOR A BOARD OF AN ACCESS FLOOR, METHOD FOR PREPARING THE BOARD OF THE ACCESS FLOOR USING THE SAME AND BOARD FOR INCOMBUSTIBILITY ACCESS FLOOR

摘要

The present invention relates to a non-combustible composition for a double floor board, a method for manufacturing a double floor board using the same and a non-flammable double floor board, more specifically 1 to 90% by weight of stone powder, 1 to 30% by weight of a flame retardant for curing , Non-combustible composition for a double-floor plate comprising 1 to 80% by weight of organic fibers or inorganic fibers and 1 to 80% by weight of fly ash or bottom ash, a method for producing a double-floor plate using the composition and the method It relates to a plate for a double floor material prepared by.;According to the present invention, it is environmentally friendly while using waste materials, and it is excellent in hardness, strength, water resistance, etc. by reinforcing the disadvantages physically and chemically compared to the existing materials, and is inexpensive, and above all, non-combustible performance according to the composition ratio It is possible to provide an excellent non-flammable composition for a plate of a double bottom material, a method for producing a plate for a double floor material using the same, and a plate for a non-combustible double floor material.
