The invention relates to a panel for constructing a floor or wall covering. The panel comprises a substantially planar top surface, at least one core layer composed of a composite material which core layer is provided with the cavities, and a bottom surface. The panel further comprises at least one pair of opposite edges, said pair of opposite edges preferably comprising complementary coupling parts configured for mutual coupling of adjacent panels.

A decoupling mat (1) for a surface covering structure that can be covered by covering elements has a strip- or plate-shaped compensation element (2) which has upwardly projecting formations (4) arising from a lower support plane (3), which formations from an upper covering plane (6) at a distance from the lower support plane (3) and are arranged spaced apart from one another and have at least in sections an undercut (8) along their periphery. A water-permeable cover is fixed on a bottom side (12) of the lower support plane (3) and prevents penetration by a viscous adhesive into the upwardly projection formations (4). On at least some formations (4), the undercuts (8) are arranged along a region, extending in a curved manner, along a side wall of the upwardly projecting formations. A plurality of the first undercuts (8) is oriented in a first direction and a plurality of second undercuts (8) is oriented in a second direction. The cover may have a perforation or consist of a water permeable textile woven fabric or sheet, or of a water permeable non-woven fabric (13). A plurality of adjacent formations (4) are respectively connected to one another by ventilation ducts (7) projecting from the lower support plane (3), wherein the ventilation ducts (7) do not extend up to the upper covering plane (6).

A sound insulation flooring material according to the present invention in which a heat resistance, sound insulation, and adhesion are improved is implemented by sequentially stacking a plurality of layers, a first balance layer, a second balance layer, a primer layer, a PE foam layer, and a PE release paper layer. In this case, the primer layer includes a first composition, a second composition, and a curing agent, and the first composition includes a resin, propanol, 1-methoxy-2-propanol, propyl acetate, isopropanol, butanone, and water.

A method for attaching an underlay element to a weight-reduced board element. The method includes providing a board element and an underlay element, wherein a rear side of the board element includes a groove portion and a remaining portion. The groove portion includes at least one groove. An adhesive is applied on at least a portion of the remaining portion and/or on at least a portion of a corresponding residual portion of the underlay element, and the underlay element is arranged on the rear side of the board element, such that the adhesive contacts the underlay element and the rear side.

The invention relates to composite floorings, more particularly to a soundproof composite flooring of magnesium sulfate and solid wood. The soundproof composite flooring includes a paint layer, a solid wood layer, a magnesium sulfate substrate layer, and a soundproof layer which are sequentially arranged from top to bottom; the solid wood layer and the magnesium sulfate substrate layer are bonded via AB glue by cold pressing or via a hot-melt adhesive; a plurality of cylindrical holes are arranged along edges of an upper surface of the magnesium sulfate substrate layer, and a buffer structure is arranged in each of the cylindrical holes; the buffer structure includes a rubber base which fits a bottom of the cylindrical holes, and a support disk which is opposite to the solid wood layer. The rubber base and the support disk are connected by a rubber column.

The present application provides a non-slip board, relating to a technical field of non-slip materials, and aims at solving the problem that after long-term use, the flooring and the sound insulating pad have problems such as deformation, corner warping and the like due to expansion and contraction, which also causes displacement on the base surface. The present application further provides a production process of the non-slip board, in which the non-slip coating layer is applied to a sound insulating pad, a soft resilient floor board, a coiled material, a homogeneous coiled material or a hard floor board, and the sound insulating pad, the coiled material or the hard floor board is not prone to displacement after being laid onto the foundation ground.

A multi-layer modular flooring system provides a permanent covering for a ground surface. The flooring system comprises multiple floor panels that detachably fit together to cover the ground surface. The flooring system has two adjacent, parallel layers disposed flush against each otheran upper layer that is the walking surface, and a lower layer that is the layer engaged with the ground surface. The upper layer comprises a surface coating, and is shaped with a protruding portion and a corresponding recessed portion that releasably couple to each other. The lower layer is disposed flush against the upper layer, and defined by a resilient, dampening composition. A ground side of the lower layer is coated with a reusable adhesive composition that allows the floor panel to detachably adhere to the ground surface. The coupling of the protruding and recessed portions, and the reusable adhesive restrict lateral motion of the floor panels.

A physically crosslinked, closed cell continuous foam structure derived from recycled metallized polyolefin material; polypropylene, polyethylene, or combinations thereof, a crosslinking agent, and a chemical blowing agent is obtained. The foam structure is obtained by extruding a structure comprising a foam composition, irradiating the extruded structure with ionizing radiation, and continuously foaming the irradiated structure.

The invention relates to a tile, in particular a carpet tile. The invention also relates to the use a tile according to the invention as floor tile, wall tile, or ceiling tile. The invention further relates to a tile covering consisting of a plurality of tiles according to the invention. The invention additionally relates to a carpet covering consisting of at least one carpet tile according to the invention.

A composite material steel sheet comprises: at least one steel sheet, and a resin-impregnated paper composite layer, wherein the resin-impregnated paper composite layer may comprise stacked sheets of paper, and impregnated resin provide adhesion between the sheets of paper in contact with each other.
