Coal ash lightweight board

Abstract

The invention discloses a light-quality partition of pulverized fuel ash. The raw materials of the light-quality partition comprise pulverized fuel ash, cement, perlite, polypropylene fiber, water reducing agent, acrylic emulsion, foaming agent and water, and each component of the raw materials is calculated in ratio by weight: 40-60 portions of the pulverized fuel ash, 15-25 portions of the cement, 5-10 portions of the perlite, 0.1-0.5 portions of the polypropylene fiber, 0.5-1.0 portions of the water reducing agent, 1.0-5.0 portions of the acrylic emulsion, 0.1-0.5 portions of the foaming agent and 20-30 portions of the water. The invention takes the pulverized fuel ash as the main raw material; besides, various components are added into the pulverized fuel ash so as to be mixed organically. The invention not only conforms to the energy saving, waste utilizing, environmental protection policy advocated by the State, but also improves the intensity and toughness of the plates and leads the plates to be uneasy to be broken.

Description

technical field [0001] The invention relates to a lightweight board for construction, in particular to a lightweight board with fly ash, which is suitable for assembling inner or outer walls of buildings and belongs to the field of building materials. Background technique [0002] Fly ash is the fine powder waste residue produced during the power generation process of thermal power plants. The annual discharge of fly ash in my country is about 100 million tons. In order to save energy, my country encourages the use of fly ash to produce building materials. The utilization rate of coal only reaches about 30% of its total emissions. In terms of building materials, most of them are used to produce low-end products such as fly ash blocks or insulation bricks. Although these products have certain strength, they have low toughness and are easy to Broken, it can only be used for the interior and exterior walls of non-load-bearing walls, and cannot be used in parts that require high s...

Although these products have certain strength, they have low toughness and are easy to Broken, it can only be used for the interior and exterior walls of non-load-bearing walls, and cannot be used in parts that require high strength and toughness, especially for large-area panels used for wall decoration or roofing. At present, there is no proposal to use fly ash as the main Systematic research and large-scale production of raw materials to make products such as lightweight panels
