Abstract

The invention discloses a method for processing and molding an improved bamboo skin panel. The method comprises the following steps of: jointing non-woven fabrics, hot melt adhesive and bamboo skin in turn or directly attaching the non-woven fabrics and the hot melt adhesive to the bamboo skin by using a Bristol board; molding a bamboo skin side with plastic after the mixture is solidified and shaped; removing the non-woven fabrics and the hot melt adhesive by a grinding method, or directly removing the Bristol board; and spraying a corresponding coating on the surface of the bamboo skin to obtain a surface layer. A bamboo skin layer is jointed with a plastic layer, so that the hot melt adhesive is prevented from being blended with the plastic, corresponding air bubbles are prevented and the panel can finally keep higher flatness. After the outer non-woven fabrics and the hot melt adhesive are removed by grinding or the Bristol board is removed, the surface effect of the bamboo skin is not affected, soft flocks are not produced on the bamboo skin and the bamboo skin does not crack. The panel is made of a natural material, is accordant with the concept of environmental protection and has natural texture and color of the bamboo skin, so that the textural quality of a product can be improved. The method can be widely applied to the field of China compulsory certification (3C) home appliances and any product of which the structure is similar to that of a decorative lighting and that of an automobile interior trim.

Summary of the invention

The present invention is intended to propose a kind of improved bamboo skin panel production and processing method, adopt the panel of former green material bamboo skin as the surface, adopt natural material, the applying environmental protection concept, natural texture color with bamboo skin, foaming phenomenon in the time of simultaneously can effectively avoiding PUR and plastic cement to melt makes the bamboo skin panel produced can be not wrinkling and have a better flatness.

The objective of the invention is to be achieved through the following technical solutions:

A kind of improved bamboo skin panel processing molding method, at first with nonwoven, PUR, bamboo skin three combination successively or directly with western paperboard and the applying of bamboo skin, with that face of bamboo skin and plastic rubber shaping, adopt the method for grinding again after the fixed typing for the former, nonwoven and PUR is worn; Directly western paperboard is removed for the latter.

Further, with nonwoven and PUR is worn or western paperboard removed after, in the corresponding coating of bamboo skin surface spraying as surface layer.

Further, described bamboo micromicro adopts natural material bark, animal skins to substitute.

Bamboo skin panel production and processing method of the present invention, original process is improved, adopt nonwoven, PUR, bamboo skin three successively in conjunction with or directly make the bamboo skin fixed with the mode of bamboo skin applying with western paperboard, form an integral body, can not produce cracking man-hour thereby add, the bamboo cortex is directly combined with plastic layer, both have better bond strength, avoided the fusion of PUR and plastic cement, can not produce corresponding bubble, make panel finally can keep better flatness, outer field nonwoven and PUR do not influence the surface effect of bamboo skin after worn or western paperboard removes.The bamboo skin panel that adopts this method to produce adopts natural material, the applying environmental protection concept, and have the natural texture color of bamboo skin, can promote the texture of product, and defect rate is low, can be widely used in 3C field of household appliances and any structure and lamp decoration, automotive trim structure similar products like.

Description of drawings

According to embodiment and accompanying drawing the present invention is described in further detail below.

The usual bamboo skin panel processing molding method principle schematic that adopts of Fig. 1;
