A kind of preparation method of bamboo floor with excellent compression resistance

Abstract

The invention discloses a method for making a bamboo floor with excellent compression resistance. The bamboo floor with excellent compression resistance is composed of a surface layer and a base layer, the material of the surface layer is hemp bamboo, and the material of the base layer is From top to bottom, one layer of moso bamboo and one layer of hemp bamboo are interlaced and stacked layer by layer. The specific production steps of the bamboo floor with excellent compression resistance are: material selection, yellowing and greening, rolling and crushing, high temperature carbonization, low temperature Drying, dipping, filtering and drying, hot pressing. The present invention changes the raw material from the original single moso bamboo to the combination of hemp bamboo and moso bamboo. Using hemp bamboo as the surface material, and through the combination of hemp bamboo and moso bamboo, and the change of the phenolic adhesive formula, the surface density and smoothness of the bamboo floor are effectively ensured, and the bonding effect between the bamboo floor layers is greatly improved.

Description

technical field [0001] The invention relates to a bamboo floor and a preparation method thereof, in particular to a preparation method of the bamboo floor with excellent compression resistance. Background technique [0002] Bamboo flooring is a new type of building decoration material, which is made of natural high-quality bamboo through several processes. Bamboo wood flooring is wear-resistant, pressure-resistant, moisture-proof, and fire-resistant. Its physical properties are superior to solid wood flooring, its tensile strength is higher than that of solid wood flooring, and its shrinkage rate is lower than that of solid wood flooring. . Therefore, it has a wider market demand. Existing bamboo floors are generally prepared from a single material (moso bamboo), and the specific steps are: moso bamboo→cut off→flatten the outer bamboo joints→open strips→remove inner knots→planing on both sides of the bamboo strips (remove bamboo green , Bamboo yellow) → cooking (insect-pr...

AI Technical Summary

Problems solved by technology

Moso bamboo fiber is shorter than hemp bamboo fiber, so it has better hardness, but poor toughness

Ma bamboo has good toughness, but poor hardness.

Therefore, although the bamboo floor produced by purely using moso bamboo as raw material has high hardness, its toughness is relatively poor.

Moreover, the fibers of moso bamboo are arranged vertically, which leads to the disadvantages of relatively low surface density and smoothness in the produced products.

After the material is hot-pressed and glued, the layers are parallel to each other, the bonding effect is low, and its compressive performance and radial bending strength are also reduced.
