On-line synchronous registering co-extrusion SPC floor includes a base material layer, a decorative layer, and a wear-resistant layer. The decorative layer is arranged on the base material layer and provides patterns and designs. The wear-resistant layer is arranged on the decorative layer, is a transparent layer or a semi-transparent layer, and is provided with a concave-convex surface. The patterns or designs correspond to the concave-convex surface; the base material layer is composed of an elastic layer, a strength layer, and a stable layer, and shading is pressed on the bottom layer of the stable layer. Two co-extrusion lines are used for simultaneous extrusion to achieve an ABA three-layer effect of an SPC base material layer. A calender matches a synchronous registering system, and the patterns of the decorative layer are formed in a rolling manner.

On-line synchronous registering co-extrusion SPC floor and production process therefor

A foam flooring includes a stone-plastic base material structure, which sequentially comprises, from top to bottom, a first stable layer, a foaming layer and a second stable layer. The first stable layer and the second stable layer are both sheets with a PVC resin and filler powder as main components, with 25-40 parts by mass of the PVC resin and 55-75 parts by mass of the filler powder; and the density of the SPC foam flooring is 1.4-1.6 g/cm3. The foaming layer is arranged between the two stable layers, such that the overall density of the flooring is significantly reduced and reaches 1.4-1.6 g/m3; since the foaming layer is arranged inside, the surface strength of the overall flooring is not influenced.

Co-extrusion SPC foam flooring and manufacturing method thereof

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.
