Embodiment 1

[0033]Embodiment 1: with the four-year-old moso bamboo pole, except the bamboo base and the bamboo tip, the cut length is 1500mm bamboo section, the inner and outer joints are removed, the diameter is split into 17mm wide thick bamboo slices, and then the string is cut into three layers, bamboo green slices 4. Bamboo meat slices 5, bamboo yellow slices 6, and bamboo green slices 6 have a thickness of 4mm at the center line. Cook or carbonize with steam. After drying, cut off the thin edges on both sides to increase the side glued surface. Glue the sides, vertically horizontal Arranged neatly, with the plane facing upwards and the curved surface facing downwards, two adjacent green bamboo pieces are arranged upside down at intervals, so that the assembled boards will not become trapezoidal flat plates, and the bamboo green boards are pressed sideways as the bottom layer of the laminated board; then the bamboo yellow strings Splitting or radially splitting and pressing to form ba...

Embodiment 2

[0034] Embodiment 2: be used as indoor floor, then bamboo section is long 1000mm, and bamboo meat sheet 5 strings are split again, and roll is rolled into bamboo meat connecting silk sheet, thick 2mm, wide 20mm, carry out micro-carbonization treatment, soak phenolic glue, the solidification of glue Content 4%, be spread on the bamboo yellow core layer 2 as described in embodiment 1 after drying and make surface layer 1, pressure 30Mpa, heating 140 ℃, hot pressing 60min, all the other are with embodiment 1.

Embodiment 3

[0035] Embodiment 3: As an interior wall decoration board, the core layer 2 and the bottom layer 3 are prepared as in Example 1, the bottom layer 3 is facing outward, the core layer 2 is facing inwardly against the wall, and the bamboo green board is facing outwardly to show the bamboo country style.

Abstract

A laminated sheet of tabasheer core layer and bamboo green base layer includes a core layer, a base layer, characterized in that the core layer is composed of the connecting thread sheets cleaved by the raw materials of tabasheer, bamboo base part, bamboo tip part, concave thickness sheet and the glue, the base layer is arranged vertically with bamboo fiber of the base layer, core layer, side jointed board of bamboo green sheet cleaved to inner plane and outer arc face by the raw materials of bamboo green; the manufacturing method of the laminated sheet has following steps made by working procedures of pretreating, cooking, glue blending and drying of the raw material, vertical jointing board, paving and hot pressing of the bamboo green sheet, which can widely use as floor, wallboard, furniture panel, wrapper plate and so on, with advantages of high mechanical strength, high utilization rate, less procedure, quick work efficiency, low cost, remarkable economic benefit and ecological benefit of bamboo material.

Description

technical field [0001] The invention relates to a laminated board of a bamboo yellow core layer and a bamboo green bottom layer and a processing method thereof. A laminate made of base and bamboo tip as raw materials and a processing method thereof. Background technique [0002] In many bamboo processing industries, only bamboo meat is used as raw material, and bamboo green and bamboo yellow are used because they contain wax, sio 2 , difficult to glue and other reasons and discarded; the bamboo base and bamboo tip of the original bamboo have a large tip, it is difficult to obtain strips of similar width or thickness, and they are often discarded; There is a longitudinal groove everywhere, and the bamboo slices split in the chord direction here are not smooth, and they are concave thin slices, which cannot be used. Therefore, the effective utilization rate of whole bamboo stalk is about 30%, and nearly 70% of the part is discharged outside the raw material of bamboo process...
