Abstract

The invention provides a solid-waste-based PVC wear-resistant wood grain film and a preparation method thereof, and belongs to the field of PVC calendering film base materials. The wood grain film comprises polyvinyl chloride, a plasticizer, a stabilizer, titanium dioxide, superfine steel slag powder, superfine desulfurized fly ash powder and superfine silica fume powder. A superfine tire vertical mill and a heating device of the superfine tire vertical mill are utilized to form 2000-mesh steel slag superfine powder, 2500-mesh desulfurized fly ash superfine powder and 3000-mesh silica fume superfine powder, and then the superfine powder, polyvinyl chloride, a plasticizer, a stabilizer and titanium dioxide are prepared into the wood grain film. According to the invention, the industrial bottlenecks of high price and large primary resource consumption of the PVC wood grain film produced from titanium dioxide, active nano calcium carbonate and wollastonite are solved; the hardness, wear resistance and the like of the PVC wood grain film need to be improved; the method utilizes high energy consumption of ball milling, and the processed ultrafine powder forms a spherical shape and does not have the defect of fiber characteristics. The solid waste is fully utilized, and the current industrial development requirements of energy conservation, environmental protection and circular economy are met.

Description

technical field [0001] The invention belongs to the field of PVC calendered film base materials, in particular to a solid waste-based PVC wear-resistant wood grain film and a preparation method thereof. Background technique [0002] PVC wood grain film is a typical calendered film, which can be combined with wood, plastic, aluminum plate and steel plate to make a multifunctional decorative material. It is widely used in household appliances, interior decoration, aircraft, ships, trains and billboards, etc. occasion. In the production formula of PVC wood grain film, titanium dioxide, nano light calcium carbonate, wollastonite, etc. are the most commonly used fillers. However, the prices of titanium dioxide, nano-light calcium carbonate and wollastonite continue to rise, resulting in a substantial increase in the production cost of PVC wood grain film. [0003] Steel slag is a solid waste produced in the steelmaking process, accounting for about 15% to 20% of the steelmaking...
