Embodiment

[0042] This embodiment relates to this embodiment and also relates to a method for manufacturing an environmentally friendly composite board with vertically arranged bamboo strips. The specific steps are:

[0043] Step 1: Sand one side of a 3mm thick wood chip, spray a layer of natural eucalyptus oil on the sanded surface (spray amount 20-25g / square meter), and dry naturally at 10-40°C for more than 2 hours , and then apply environmentally friendly three-bean glue. The size of the veneer is: 3mm thick, 13cm wide, and 96cm long; the veneer can be veneer or finger-jointed board;

[0044] Step 2, coating both sides of the double-sided sanded vertical bamboo strip layer with environmentally friendly three-bean glue, and pasting and pressing a layer of 3mm thick wood chips on both sides;

[0045] Step 3, heat-press the composite slab of the three-layer wood-bamboo-wood structure (wood veneer + vertical bamboo layer + veneer) at a temperature of 110-120°C and a pressure of 2.0 MPa f...

Abstract

The invention provides a manufacturing method for a bamboo strip vertical environment-friendly composite board. The manufacturing method includes the steps that firstly, one face of a veneer is sanded, natural eucalyptus oil is sprayed to the face of the veneer, drying is conducted for 2 or more hours, and then environment-friendly three-bean glue is sprayed; secondly, the two faces of a bamboo strip vertical layer are coated with environment-friendly three-bean glue; thirdly, hot pressing is conducted on a composite board blank of the wood, bamboo and wood three-layer structure; fourthly, the composite board plank is posput for 3 or more days for health maintenance, and then an environment-friendly composite material is obtained; and fifthly, grooves and tongues are sequentially formed in the four faces, namely, the two ends and the two sides, of the environment-friendly composite material, sanding is conducted, and a finished product is obtained after UV paint lines are arranged and decoration paint are sprayed on six faces. A floor manufactured from the bamboo strip vertical layer manufactured according to the method has a quite high natural solid wood sense and is environment-friendly, direct plate splicing is achieved, timber is fully used, and resources are saved; and the transverse or longitudinal flatly-placed bamboo-wood structures of bamboo strips are broken, so that the bearing strength of the bamboo strip vertical environment-friendly composite board is higher, the vertical structure of the bamboo strips and the transverse structure of veneers can fully restrain each other, and the bamboo strip vertical environment-friendly composite board is not prone to deformation.

Description

technical field [0001] The invention relates to a method for preparing a vertically arranged layer of bamboo strips, in particular to a method for manufacturing an environmentally friendly composite board with vertically arranged bamboo strips. Background technique [0002] At present, bamboo strips have been widely used as raw materials for composite materials, but most of them are horizontal structures with low load-bearing strength, and technical problems such as lack of realism, unqualified environmental protection, and easy deformation of the panels still need to be resolved. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a method for manufacturing an environment-friendly composite board with vertically arranged bamboo strips. [0004] The present invention is achieved through the following technical solutions: [0005] In the first aspect, the invention relates to a method for manufactur...
