Dipped paper mould pressing wood flooring block

Abstract

The invention relates to a dipped paper mould pressing wood flooring block which is a wood floor, comprising a surface structure, a base material and a bottom layer. The surface structure comprises a wear-resisting layer, a surface layer and a decoration layer. The bottom layer is a decorative paper board of dipping thermosetting resin, or veneers. The base material is density fiberboard providedwith a tenon and a groove which are adapted with each other and arranged at the edge of an opposite edge of the base material. The surface structure and the base material are overlapped with an edge contour area and a central area below the surface area of the walking surface; a dent-shaped strip of an arc-shaped line segment section contour with a symmetry axis vertical to the bottom surface of the floor block is pressed at the overlapped surface structure and base material. The invention provides dent-shaped strip with a cross section that is designed to accord with the press working principle, reduces the stress concentration and is provided with the waveform dent-shaped strip extending along the longitudinal direction in the central area, thereby enhancing the bending section coefficient, i.e. the bending strength. The invention can be widely paved in fields such as hotels, houses, schools, hospitals and the like.

Description

technical field [0001] The invention relates to a wooden floor, in particular to an impregnated paper molded wooden floor board. Background technique [0002] During the use of wooden floors, experience tells us that the most vulnerable part is the edge. Often the wooden floor is first eroded here, and then the corners are dropped, which will then involve adjacent parts, and finally accelerate the damage of the entire piece. In response to this undesirable phenomenon, designers have adopted improvements in structure and technology. At present, the commonly used manufacturing process of impregnated paper laminated wooden floor is to press the impregnated paper on the base material installed on the press platform under the action of high pressure of about 2400 tons and high temperature of about 200 ℃ through the template on the press. The improved structure and process is to press the pre-designed pattern on the special steel template, so when the impregnated paper laminates ...

Problems solved by technology

However, due to the fact that there must be stress concentration at the sharp corner of the V-shape during press processing, in fact, there is a certain risk of cracking at the sharp corner of the above-mentioned V-shaped pressing
