Abstract

The invention discloses a PVC floor added with coal gangue powder. The PVC floor comprises a UV coating, a wear-resisting layer, a printing layer, a filling layer and a stabilizing layer which are sequentially arranged from top to bottom. The filling layer comprises the following components in parts by weight: 20-26 parts of PVC resin, 60-70 parts of stone powder, 5-8 parts of a plasticizer, 1-5 parts of a flame retardant and 1-2 parts of a heat stabilizer, wherein the stone powder comprises at least one of coal gangue powder, marble powder and granite powder; the stabilizing layer comprises the following components in parts by weight: 25-30 parts of PVC resin, 30-40 parts of coal gangue powder, 25-45 parts of a plasticizer, 3-6 parts of a lubricant, 1-5 parts of a flame retardant and 1-2parts of a heat stabilizer. According to the invention, waste utilization is carried out on the coal gangue, and the coal gangue is used as filler of the PVC floor, so that the production cost of thePVC floor is reduced, the compression stability of the PVC floor is also improved, and the PVC floor is not easy to break and upwarp, good in usability and long in service life.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a PVC floor added with coal gangue powder and a preparation method thereof. Background technique [0002] PVC floor, also known as plastic floor, is a floor decoration material mainly produced from PVC (polyvinyl chloride) materials. Due to its superior properties such as light weight, wear resistance, fire resistance, and environmental protection, PVC flooring has gradually replaced traditional tiles and wooden floors and has become the first choice for floor materials. However, most of the existing PVC floors are filled with calcium carbonate, bentonite, etc., and their compression stability needs to be improved. [0003] Coal gangue (shale) is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal associated with the coal seam during the coal formation process....
