Document Type and Number:
Japanese Patent JP2022049956
Kind Code:
A
Abstract:
To provide a method for producing an incombustible building material board in which efflorescence is hard to be generated in a relatively short time without using water and without generating a puncture during hot press.SOLUTION: A method for producing an incombustible building material board comprises: a step in which a mixture at least comprising: an active filler as a latent hydraulic substance of 100 pts.wt.; sodium metasilicate pentahydrate of 25 to 50 pts.wt.; and sodium tetraborate decahydrate is produced; and a step in which the mixture is scattered and bedded into a flask and is thereafter subjected to hot press in the temperature range of 120 to 160°C for 15 to 30 min to mold an incombustible building material, and the sodium tetraborate decahydrate in the mixture is blended by 10 to 30 wt.% to the sodium metasilicate pentahydrate.SELECTED DRAWING: None
