New solid wood board with melamine impregnated bond paper directly attached

Abstract

A new type of solid wood board directly pasted with melamine impregnated film paper is based on a new structure of solid wood laminated wood. Paste melamine-impregnated film paper directly on the surface of the new solid wood board with stable structure. In the present invention, the thin veneer is horizontally pasted on the front and back sides of the solid wood composite board, which enhances the overall bonding force of the solid wood composite board and maintains the excellent performance of the solid wood composite board, even in environments with large dry-humidity and temperature differences. , Solid wood integrated panels are not prone to shrinkage and cracking. The formed board not only has wear-resistant, dry and wet resistance, corrosion resistance and good decorative properties on the surface; moreover, it maintains the excellent performance of solid wood integrated boards, and overcomes the drying and shrinkage of traditional integrated boards due to changes in physical environment factors in practical applications. Expansion, cold shrinkage and heat expansion, easy cracking and warping deformation.

Description

technical field [0001] The invention belongs to a new board, in particular to a novel solid wood board directly pasted with melamine-impregnated film paper. technical background [0002] At present, melamine-impregnated film paper-faced wood-based panels are mainly composed of plywood, blockboard, particleboard, fiberboard, etc., and the two sides of the substrate are respectively pasted with melamine-impregnated film paper; Paper-faced wood-based panels are mainly divided into four types: melamine-impregnated film paper-faced plywood, blockboard, particleboard, and fiberboard. Compared with solid wood sawn timber, melamine impregnated film paper veneered wood-based panels have low raw material requirements, wide sources, high wood utilization rate, many product specifications, good processing performance, and diversified surface decoration, and the surface is wear-resistant and durable. Excellent properties such as heat resistance, water resistance, chemical pollution resi...

Problems solved by technology

However, due to the various gaps in the solid wood glulam itself, during the process of directly pasting the melamine-impregnated film paper, the air in the gaps expands to cause blisters on the paper surface and damage the appearance; secondly, due to the special physical properties of wood, In the process of directly pasting the melamine-impregnated film paper at high temperature, the wood texture of the glulam itself will also be highlighted, causing confusion in the decorative texture of the melamine-impregnated film paper, which affects the senses; the third is due to the growth environment of the solid wood glulam board The degree of expansion and contraction of wood under the action of high temperature and high pressure is also different due to different lighting conditions, resulting in uneven surface after directly pasting melamine-impregnated film paper; Fourth, solid wood glulam with melamine-impregnated film paper will still warp Deformation, cracking and other defects

Due to the above reasons, it is currently difficult to directly paste melamine-impregnated film paper on the surface of solid wood glulam.
