Bamboo-wood composite board core and vertical core board using same

Abstract

The invention belongs to the technical field of artificial boards, and discloses a bamboo-wood composite board core and a vertical core board using the bamboo-wood composite board core. The bamboo-wood composite board core is formed by alternately paving and assembling a plurality of groups of board strips and a plurality of longitudinal bamboo strips and then gluing and laterally pressing the board strips and the longitudinal bamboo strips, and a plurality of transverse bamboo strips are embedded in the upper surface and the lower surface of the board core in a staggered mode; the board strips are formed by splicing a plurality of core strips in a bonding mode, each core strip is formed by cutting after a plurality of layers of veneers are assembled and hot-pressed, the overlapping direction of the veneers is located in the width direction of the core strips, and the wood grain direction of the veneers is located in the length direction of the core strips. The invention discloses a vertical core board using the bamboo-wood composite board core. The vertical core board comprises an upper decorative layer, an upper surface layer, the bamboo-wood composite board core, a lower surface layer and a lower decorative layer which are bonded with one another from top to bottom. The bamboo-wood composite board core and the vertical core board using same are high in transverse static bending intensity, excellent in deformation resistance, good in overall flatness, attractive in texture, suitable for the fields of indoor decoration, furniture manufacturing and the like, and particularly suitable for manufacturing cabinet doors such as wardrobes, cupboards, door leaves and the like.

Description

technical field [0001] The invention belongs to the technical field of artificial boards, and in particular relates to a bamboo-wood composite board core and an applied vertical core board. Background technique [0002] Due to the increasing shortage of natural wood resources, artificial panels can make full use of small-diameter wood and corner waste in the wood processing process to improve the utilization rate of wood, so artificial panels are more and more used in furniture manufacturing, house decoration, etc. field. There are many types of wood-based panels in the market, and decorative wood-based panels such as particleboard, blockboard and plywood are more commonly used. Among them, compared with other types of wood-based panels, blockboard has better nail-holding power, high strength, low moisture content, and has the characteristics of firmness, sound absorption, and heat insulation, so blockboard is the most widely used in wood-based panels.

AI Technical Summary

Problems solved by technology

Since the board cores are all wood strips processed from small-diameter logs, the material of the small-diameter wood strips is uneven, and the internal stress and deformation are large after the board core is assembled, which also leads to the production of blockboards. After a period of use, it is easy to warp the end or crack the surface, which seriously reduces its appearance and performance

In other words, the established structure of the board core is the main reason for the common quality defects of the existing blockboards such as low transverse static bending strength and poor deformation resistance.
