Abstract

A stone plastic composite (SPC) floor includes a decorative surface. The SPC floor has an SPC substrate and a decorative surface formed on the SPC substrate; the decorative surface is a wooden board or a bamboo board; the moisture content of the decorative surface is controlled within 5-7%. The SPC substrate is divided into an upper layer, a middle layer, and a lower layer, and the main components of the SPC substrate comprise polyvinyl chloride resin powder, calcium carbonate, a calcium-zinc stabilizer, an inner lubricant, PE wax, chlorinated polyethylene (CPE), acrylic ester (ACR), a composite lubricant, and a coloring agent. The SPC floor can ensure that the decorative surface does not wrap and deform, and other performances of the floor are not affected, and thus is low in costs.
