Problems solved by technology

In recent years, domestic and foreign research on how to deal with coal gangue has been carried out in depth. Among them, coal gangue is mainly used in cement production, but the utilization rate is low, and the current comprehensive utilization rate is still less than 15%.
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 in high-rise buildings on the exterior wall, and is usually fired at high temperature, which is a high-pollution and high-energy-consumption product, with safety hazards and environmental hazards coexisting
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 a method for manufacturing an exterior wall decorative board. The exterior wall decorative board is formed by laminating a decorative surface layer and a middle material layer.The decorative surface layer is externally sprayed with a decorative surface layer material, and the middle layer material is beater-addition molded by a beater-addition machine. The decorative surface layer material is prepared from the following ingredients (by weight): 100 parts of slag, 0-50 parts of coal gangue, 1-25 parts of an alkaline activator, 20-50 parts of water, 5-28 parts of pulp fiber, 1-30 parts of a pigment and 0.5-1 part of polypropylene fiber. The middle layer material is prepared from the following ingredients (by weight): 100 parts of slag, 0-70 parts of coal gangue, 1-22parts of an alkaline activator, 10-40 parts of water, 5-42 parts of pulp fiber and 0.5-2 parts of polypropylene fiber. By the technical scheme of the invention, potential hydraulicity of slag-coal gangue 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 quality of the board is guaranteed, and mass production can be realized.

Description

technical field [0001] The invention relates to a method and equipment for making exterior wall decorative panels, in particular to a method for using alkali-activated slag-coal gangue to produce exterior wall decorative panels. Background technique [0002] Coal gangue is the waste rock that is separated during the process of coal development and washing, and is one of the largest industrial solid wastes. According to statistics, the comprehensive discharge of coal gangue accounts for about 15%-20% of raw coal production, and the storage capacity has reached 7 billion tons. A large amount of coal gangue is not only a heavy burden on coal mine production, but also seriously pollutes the environment. Therefore, the treatment and recycling of coal gangue has become an inevitable problem for human beings today. In recent years, domestic and foreign studies on how to deal with coal gangue have been carried out in depth. Among them, coal gangue is mainly used in cement producti...
