Abstract

The invention discloses a preparation method of a high-strength light-weight ceramic plate, which comprises the following steps: mixing acrylic acid, gelatinized sweet potato powder, polyaspartic acid and inositol phosphate in a mass ratio of (0.3-0.9):(2.1-2.7):1:(0.1-0.4) to obtain a mixed paste I, mixing with water, regulating the pH value to 8.5-10, and mixing with ground waste ceramic tile powder to obtain a ceramic paste mixture A; and carrying out chemical pre-crosslinking and irradiation crosslinking, foaming, curing to form, drying and calcining to obtain the high-strength light-weight ceramic plate. The ceramic plate has the advantages of high strength and small density, and greatly saving the cost; and the foamed ceramic plate has uniform pore size and stable performance.

Description

technical field [0001] The invention relates to the technical field of ceramic products, in particular to a preparation method of a high-strength and light-weight ceramic plate. Background technique [0002] At present, my country's building energy consumption has accounted for 30% of the total energy consumption, and building energy conservation has become the focus of energy conservation and emission reduction. It is of great significance to develop new thermal insulation and energy-saving wall materials and improve the thermal insulation performance of external walls to achieve building energy conservation. A large number of engineering practices have proved that wall insulation technology is the best way to achieve building energy conservation and insulation. [0003] Driven by the wave of building a green and energy-saving society, people's expectations and pursuits of building energy conservation are increasing day by day, and various wall enclosure systems such a...
