A kind of fly ash floor

Abstract

The invention discloses a coal ash floor. A raw material formula is by adopting coal ash, polyvinyl chloride and polyester (PE) wax. A preparation method comprises the steps of (1) weighing 80-90 parts of coal ash, 8-12 parts of polyvinyl chloride and 4-6 parts of PE wax according to proportions in the raw material formula; (2) fully mixing and stirring the weighed materials in a closed heating stirrer, stirring 300 liters each time, and stirring for 10 minutes; (3) putting a mixture into a feeding hopper of an extruder at the temperature of 170-190 DEG C until the mixture is extruded to be an elongated semi-finished product which is 1,200 mm long, 180 mm wide and 8-15 mm thick; (4) sanding, polishing and making tenons in four surfaces; (5) performing surface treatment, and painting ultraviolet (UV) paint; and (6) packaging finished products, and putting the finished products into a library. For the coal ash floor, the coal ash can be reused, and waste can be turned into treasures; furthermore, the floor is firm and cannot absorb water; pollution is prevented; acid and alkali resistance is realized; the coal ash floor is anti-ageing, is environment-friendly and can be safely used; and radioactivity toxicity is avoided.

Description

technical field [0001] The invention relates to the field of building boards, in particular to a fly ash floor. Background technique [0002] Fly ash is one of the largest industrial wastes in my country. Fly ash is the main solid waste discharged from coal-fired power plants. With the development of the power industry, the discharge of fly ash from coal-fired power plants has increased year by year, polluting the atmosphere. , the toxic chemical substances in it will also cause harm to human body and organisms, and the resource reuse of fly ash has become the most effective way to deal with industrial waste. At present, apart from solid wood flooring, the floor is mainly composite flooring. Although the price is relatively lower than solid wood flooring, because most of them are wood-based panels, the formaldehyde content often exceeds the standard. The use of such products will cause great harm to human health. There are radiation hazards as widely used floor tiles. Cont...
