Abstract

The invention discloses a preparation method of a microcrystalline foam thermal insulation decorative plate through lithium deposition sintering. The preparation method sequentially comprises the following steps: treating lithium deposition mother liquor; drying the high-concentration lithium ion solution; melting at high temperature; carrying out water quenching; drying and crushing; carrying outcrystallization and a foaming heat treatment; annealing and demolding; and processing. According to the preparation method of the microcrystalline foam thermal insulation decorative plate, a large amount of lithium deposition mother liquor can be consumed; therefore, the lithium deposition mother liquor can be fully recycled; the economic loss in the original production process of the lithium deposition mother liquor can be effectively reduced; and meanwhile, the lithium deposition mother liquor can be used for preparing the microcrystal foam thermal insulation decorative plate, so that the environmental protection effect of the preparation process of the microcrystal foam thermal insulation decorative plate can be effectively highlighted, and the use value of the preparation method of the microcrystal foam thermal insulation decorative plate is highlighted.

Description

technical field [0001] The invention relates to the technical field of thermal insulation decorative boards, in particular to a method for preparing thermal insulation decorative boards sintered with lithium-precipitated microcrystalline foam. Background technique [0002] Thermal insulation decorative panels are also called thermal insulation and decorative integrated panels, also called integrated panels, which are composed of thermal insulation materials and decorative panels. There are all kinds of thermal insulation decorative panels, but the production and processing of some thermal insulation decorative panels are not environmentally friendly, and even other wastes are produced during the production process, which will cause great adverse effects on the external environment. [0003] Lithium precipitation is the lithium precipitation mother liquor produced by extracting lithium salt from lithium ore by evaporation and crystallization process. Since the lithium precipi...
