Sintering project abandoned soil expanded perlite heat insulation and decoration integral board and preparation method thereof

Abstract

The invention discloses a sintering project abandoned soil expanded perlite heat insulation and decoration integral board, which consists of a heat insulation base layer and a decoration surface layer, wherein the heat insulation base layer is prepared from 50 to 80 parts of engineering waste soil, 50 to 80 parts of expanded perlite, 5 to 10 parts of bonding agents, 0.5 to 1 part of foaming agents, 2 to 6 parts of foam stabilizing agents, 6 to 8 parts of reinforced fiber, 0.2 to 0.3 part of cosolvents and 30 to 50 parts of water through sintering; the decoration surface layer is prepared from20 to 70 parts of silicon dioxide, 30 to 80 parts of zinc oxide, 5 to 8 parts of boric oxide, 2 to 4 parts of aluminum oxide, 0.5 to 2 parts of lithium oxide, 0.5 to 3 parts of coloring agents, 0.2 to0.3 part of dispersing agents, 0.1 to 0.4 part of anti-foaming agents and 20 to 40 parts of water through sintering. The solid wastes are efficiently utilized; meanwhile, the prepared sintering project abandoned soil expanded perlite heat insulation board has the integral functions of fire prevention, heat insulation and decoration.

Description

technical field [0001] The invention belongs to the field of building materials, and specifically relates to a sintering project spoil expanded perlite thermal insulation and decoration integrated board and a preparation method thereof. Background technique [0002] Building energy consumption has exceeded 1 / 3 of the total energy consumption of society. Improving the thermal insulation performance of building envelope is an effective means to reduce building energy consumption. Organic insulation materials commonly used in buildings, such as polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane board (PU), etc., have low thermal conductivity and good thermal insulation performance, but due to their poor fire resistance and durability It has been unable to meet the development needs of building fire protection and safety. Inorganic insulation materials such as rock wool, expanded perlite, and expanded vermiculite have good fire resistance, chemical stabili...

AI Technical Summary

Problems solved by technology

But their obvious disadvantages are: (1) The expansion perlite slab is prepared by pressing, which causes the expansion perlite to be broken and affects the thermal insulation performance of the board; The density of the board is increased, which leads to a further increase in the thermal conductivity of the board; (3) It does not have the integrated effect of heat preservation and decoration. After the board is installed on the wall, it needs to be plastered and decorated, resulting in cumbersome construction technology and increased costs.
