Problems solved by technology

[0003] In the prior art, the bamboo composite material prepared with radial bamboo strips as a unit has the advantages of high material utilization rate, less glue consumption, high strength-to-weight ratio of the plate, and low production cost, but there is also a large porosity of the plate. , poor flatness defects
Bamboo composites prepared by rolling and decomposing bamboo bundles have the advantages of high density, less pores, smooth surface, etc., but there are some problems such as low material utilization rate and board strength-to-weight ratio, glue consumption and production costs. high defect
At the same time, bamboo is a natural biomass material, which has defects such as poor fire resistance and easy combustion.
The existence of the above problems has seriously restricted the application fields of bamboo and the market competitiveness of products.

Embodiment 1

[0042] like figure 1 As shown, the manufacturing method of the high-strength bamboo composite reconstituted material of a three-layer hybrid structure of the present embodiment specifically includes the following steps:

[0043] (1) Preparation of radial bamboo strips: sawing fresh moso bamboo into bamboo tubes with a length of 1.5 m, and after removing green and yellow, the bamboo tubes were processed into radial bamboo strips with a thickness of 1.5 mm using a radial breaking machine.

[0044] (2) Bamboo bundle preparation: sawing fresh moso bamboo into a bamboo tube with a length of 1.5m, using a bamboo dispersing machine to split the bamboo tube into bamboo pieces with a width of 30mm, removing the bamboo green and then using a decompression machine to decompose it into horizontal loose, Longitudinal bamboo bundles.

[0045] In this application, the size of the bamboo bundle is inconsistent with the bamboo strip, and there is no specific requirement for the thickness. Be...

Embodiment 2

[0064] like figure 1 As shown, the manufacturing method of the high-strength bamboo composite reconstituted material of a three-layer hybrid structure of the present embodiment specifically includes the following steps:

[0065] (1) Bamboo bundle curtain preparation: cutting fresh moso bamboo into a bamboo tube with a length of 2.0m, using a bamboo dispersing machine to split the bamboo tube into bamboo pieces with a width of 25mm, removing the green bamboo and using a decompressor to roll it into horizontal looseness, After the longitudinally connected bamboo bundles are loosened, the bamboo bundles are woven into curtains in parallel with a weaving machine. The distance between adjacent bamboo bundles is not greater than 2mm, and the distance between adjacent sutures is 0.4m, resulting in a length of 1.5m and a width of 2.0 m bamboo beam curtain.

[0066] When using bamboo bundles to weave bamboo curtains, the size of the bamboo bundles only needs to be evenly matched, no s...

Abstract

The invention discloses a method for manufacturing a high-strength bamboo composite reconstituted material. Treatment; when forming the slab, the mixed bamboo strips of the core layer of the slab are arranged in random directions, the bamboo bundle curtains on the upper and lower layers are continuously lengthened and sprayed with fire-retardant and flame-retardant solution, and cut off when the preset length is reached to obtain a slab; The blanks are sequentially hot-pressed and post-treated to obtain high-strength bamboo composite reconstituted materials. The high-strength bamboo composite reconstituted material prepared by the invention has the characteristics of continuous paving operation, high utilization rate of bamboo materials, large strength-to-weight ratio, fire resistance and flame retardant.

Description

technical field [0001] The invention belongs to the field of manufacturing bamboo composite reconstituted materials in the wood industry, and particularly relates to a continuous pavement, high-strength bamboo composite reconstituted material with fire-retardant and flame-retardant functions, and a manufacturing method thereof. Background technique [0002] my country is rich in bamboo resources, the area of ​​bamboo forest and the volume of bamboo are the largest in the world, and bamboo has the advantages of high strength-to-weight ratio, short maturity period, and sustainable utilization of one-time planting. An important measure of shortage. It is one of the most important ways to realize the industrialized utilization of bamboo materials by splitting bamboo materials into radial bamboo strips or rolling them into loosened bamboo bundles, and then recombining them into boards under high temperature and high pressure conditions. [0003] In the prior art, the bamboo compo...
