Problems solved by technology

Exterior wall paint is safe, rich in color, and easy to update, but it has poor protection performance on the wall such as crack resistance and weather resistance, and is easy to get dirty and fade; while the reflection of glass curtain wall, the high density of ceramic hanging board and the appearance The wall brick itself is heavy, which brings potential danger to the use of high-rise buildings on the outer wall, and is usually fired at high temperature. It is a high-pollution and high-energy-consuming product, and both safety hazards and environmental hazards coexist.
Metal exterior wall decoration materials such as aluminum panels and aluminum-plastic panels are difficult to popularize due to their high cost and complicated installation requirements

Abstract

The invention provides an extrusion-molded alkali-activated steel slag-alkaline residue exterior wall decorative board. The exterior wall decorative board is formed by laminating a decorative surfacelayer and a middle material layer. The decorative surface layer is externally sprayed with a decorative surface layer material, and the middle material layer is prepared from an extrusion-molded middle layer material. The decorative surface layer material is prepared from the following ingredients (by weight): 100 parts of steel slag, 30 parts of alkaline residue, 21 parts of an alkaline activator, 42 parts of water, 19 parts of pulp fiber, 5 parts of a pigment, and 1.1 part of polypropylene fiber. The middle layer material is prepared from the following ingredients (by weight): 100 parts of steel slag, 40 parts of alkaline residue, 15 parts of an alkaline activator, 36 parts of water, and 40 parts of pulp fiber. By the technical scheme of the invention, potential hydraulicity of steel slag-alkaline residue is fully utilized, a high-strength product which achieves various performance indexes of the exterior wall decorative board is generated at a high hydration speed, the blank qualityof the board is guaranteed, and mass production can be realized.

Description

technical field [0001] The invention relates to a decorative board, in particular to a preparation method of an exterior wall decorative board. Background technique [0002] Steel slag is a by-product of the steelmaking process, and its emissions are about 10-15% of steel production. At present, the comprehensive utilization rate of steel slag is only 10%. Nearly 90 million tons of steel slag are not effectively utilized every year. The stacking and idleness of a large amount of steel slag not only takes up a lot of cultivated land, but also contains heavy metal ions and alkali metal ions in steel slag. It will seep into the soil and cause groundwater pollution. [0003] Alkali slag refers to the alkaline waste slag discharged in the process of alkali making and alkali treatment in industrial production, including the waste slag discharged in the process of making alkali by ammonia-soda method and the alkaline waste slag discharged in other industrial production processes. ...
