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.

Stone plastic composite (SPC) floor comprising decorative surface

The invention relates to a bamboo floor, in particular to a composite bamboo floor. The composite bamboo floor comprises a floor surface board provided with a body, a pressed surface, a connecting surface connected with the core board, at least one cut surface board side face and surface board end faces, and the core board arranged under the floor surface board and provided with a core board surface connected with the floor surface board, a core board bottom surface, core board side faces and core board end faces, and the positions of the core board side faces or the core board side faces and the surface board side faces are provided with notch structures processed in two sides in the length direction of the composite bamboo floor. The composite bamboo floor is high in strength, high in processing efficiency and low in production cost.

Composite bamboo floor and manufacturing method thereof

The present invention relates to an outdoor bamboo floor and a manufacturing method thereof, in particular, to an outdoor bamboo floor subjected to an immersion treatment using hot oil. Conduits or other capillary structures of a bamboo material in the outdoor bamboo floor of the present invention are filled with an oil medium, with an oil content of 2-10%. The manufacturing method includes immersing a plate blank of the bamboo floor in a hydrophobic organic medium at 100-300&#xb0; C. for 1-10h, and are statically cooled down to a room temperature after being taken out.

Outdoor bamboo floor

A polyvinyl chloride (PVC) flooring, includes a wear-resistant layer, a decorative layer and a substrate layer from top to bottom in order, wherein the substrate layer comprises a flexible layer, a strength layer and a correction layer from top to bottom in order and the hardness of the strength layer is 1.05-1.10 times that of the flexible layer and the correction layer.
