Problems solved by technology
[0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defect that the surface layer of the recombined bamboo board is easy to crack during long-term use caused by the secondary pressing of the existing recombined composite floor, and to provide a crack-proof recombined composite floor. Floor and its processing method, the recombined composite floor made by using the processing method will not crack on the surface after long-term use

Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] Such as figure 1 Shown, a kind of anti-cracking recombined composite floor, comprises the recombined bamboo board 1 of surface layer and several layers of composite boards (not shown in the figure) below it, the surface of recombined bamboo board 1 is provided with primer layer 2 from inside to outside , a putty layer 3, an adhesive film base layer 4, and a protective paint layer 5. The recombined bamboo board is formed by pressing bamboo bundles randomly placed in the same direction, and the primer layer 2 is a colored water-based paint layer.
[0020] An anti-cracking processing method for recombined composite flooring, comprising the following steps carried out in sequence.
[0021] a, make primer, smear water-based paint to form primer layer 2 on the surface of the recombined composite floor (that is, the surface of the restructured...

The invention relates to the field of recombined bamboo floor manufacturing, in particular to an anti-cracking recombined composite floor and a processing method thereof, aiming at the technical defect that the floor surface is easy to crack in the using process as the traditional recombined composite floor is manufactured by adopting secondary lamination. The invention provides an anti-cracking recombined composite floor and a processing method thereof. The anti-cracking recombined composite floor comprises a floor body with a recombined bamboo board on the surface layer and is characterizedin that an adhesive film base layer which is formed after PUR (Polyurethane) thermosol is solidified is arranged on the surface of the recombined bamboo board, and protection paint is coated on the adhesive film base layer to form a protection paint layer. The adhesive film base layer formed by the PUR thermosol is firmly adhered on the recombined bamboo board on the surface layer of the composite floor as elastic adhesive base cloth, therefore, the anti-cracking recombined composite floor avoids the surface of the recombined bamboo board from cracking resulted from internal stress and has good anti-cracking effect as well as favorable masking and covering roles on emerged tiny cracks.
Description
technical field [0001] The invention relates to the field of recombined bamboo floor manufacturing, in particular to an anti-crack recombined composite floor and a processing method thereof. Background technique [0002] The existing recombined composite floor has a multi-layer structure, the surface layer is a recombined bamboo board, and the lower layers are composed of more than two layers of solid wood boards criss-crossed and bonded, plywood and solid wood bottom boards are bonded, and bamboo chips are bonded with single or multiple layers under high temperature and high pressure. There are three types of plywood and fiberboard. In addition, the lower layers can also be other composite boards. The surface layer and other layers of this recombined composite floor are made by pressing separately, and then they are uniformly stacked in the mold for secondary compression to form a finished recombined composite floor, because the secondary compression will destroy the alread...
