Problems solved by technology

Most of the formaldehyde content of composite flooring on the market exceeds the standard. The use of such products has caused serious harm to human health.
In addition, there is also PVC plastic floor, which is not afraid of water, environmentally friendly, and quiet, but at the same time, it is not flame-retardant, anti-static, and anti-aging. Intrude into and damage the base of the plastic floor, otherwise it will reduce the service life

Abstract

The invention discloses a coal ash composite floor. The coal ash composite floor is prepared from the following raw materials by weight: 130-132kg of 280-300-mesh coal ash, 8-10kg of 80-100-mesh coal ash, 0.05-0.06kg of 1mm rock wool, 45-48kg of PVC, 13-15kg of 1100-1200-mesh talcum powder, 1.4-1.5kg of lead salt composite stabilizer, 0.1-0.12kg of AC foaming agent, 1.8-2kg of CPE (chlorinated polyethylene), 0.7-0.8kg of ACR401 and 1.5-1.6kg of PE wax. A preparation method of the coal ash composite floor comprises the following steps: weighing the materials; pouring the weighed coal ash and talcum powder in a hot blending mixer, stirring, then adding the PVC, stirring, then adding the other materials, and stirring to obtain a mixture; putting the mixture in a storage hopper of an extruder, and controlling the feeding amount of the mixture by controlling the spiral revolution of the extruder; carrying out extrusion molding on the mixture to obtain a green body; cutting, polishing and slotting the green body to prepare a semi-finished product; and carrying out varnish stoving on the semi-finished product to prepare a finished product. By virtue of waste utilization, the semi-finished coal ash composite floor is capable of saving energy and protecting environment.

Description

technical field [0001] The invention relates to the floor field, in particular to a fly ash composite floor. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. Fly ash is one of the largest industrial wastes in my country. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing year by year. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to human beings and organisms. [0003] Composite flooring is a ground decoration material made of medium-density wood-based panels or high-density wood-based panels through molding, film covering, trimming, and joint cutting. Among them, the content of formaldehyde is a key indicator related...
