Abstract

The invention relates to a method for preparing an inorganic structural material, and particularly relates to an ultra-thin vermiculite-based fire-proof plate and a preparation method thereof, belonging to the crossing field of fire science and building and ornament materials. The ultra-thin vermiculite-based fire-proof plate is prepared from magnesium oxide, magnesium chloride, magnesium sulfate, water, fiberglass mesh, fiber glass filament, aluminium dihydrogen phosphate, trisodium phosphate, vermiculite powder, and coal ash. According to the fire-proof plate and the preparation method thereof, free magnesium chloride is the root cause to generate water drops on the vermiculite-based fire-proof plate, and by regulating the formula of magnesium oxide and magnesium chloride, and adding magnesium sulfate and coal ash, the prepared vermiculite-based fire-proof plate is smooth, does not warp and deform, and avoids generating water drops.

Description

technical field [0001] The invention relates to a method for processing and preparing an inorganic structural material, in particular to an ultra-thin vermiculite-based fireproof board and a preparation method thereof, which belong to the intersection field of fire science and building decoration materials. Background technique [0002] Ultra-thin fireproof board can be used as a substitute for wood packaging in the packaging industry, and can replace asbestos tiles, kiln-fired tiles, and glazed tiles in the building materials industry, or can be made into building material components to replace some Portland cement products. my country's annual packaging wood consumption is 5 million m 3 , using ultra-thin fireproof boards for packaging, can save more than 200,000 m per year 3 . For a country lacking in forest resources like my country, it is very economically meaningful to develop and adopt a large amount of wood substitute materials. In terms of building materials, the...
