Bamboo-wood composite container base plate with improved bamboo curtain splint surface layers, and manufacturing method thereof

Abstract

The invention provides a bamboo-wood composite container base plate with improved bamboo curtain splint surface layers, and a manufacturing method thereof. The bamboo-wood composite container base plate with improved bamboo curtain splint surface layers is characterized in that each half of the bamboo-wood composite container base plate comprises an improved bamboo curtain splint surface layer, two to three bamboo curtain splints (or two to three wood single boards) and wood single board with transverse textures, wherein the improved bamboo curtain splint surface layer, the two to three bamboo curtain splints (or two to three wood single boards) and the wood single board with transverse textures are orderly arranged from outside to inside; the bamboo curtain splints and the wood single board with transverse textures are arranged at intervals from outside to inside; the bamboo curtain splints can be replaced by wood single boards and when the bamboo curtain splints are replaced by wood single boards, the innermost three wood single boards have longitudinal textures; and phenolic resin impregnated material layers are arranged at the outermost sides of the bamboo-wood composite container base plate with the improved bamboo curtain splint surface layers. The manufacturing method comprises the following steps of 1, treating the wood single boards to enable the wood single boards to have water content less than or equal to 10%, coating double surfaces of each one of the wood single boards with glue, and aging or drying at a low temperature, and 2, assembling the wood single boards, the improved bamboo curtain splint surface layers, the bamboo curtain splints and the phenolic resin impregnated material layers to obtain a plate blank and carrying out hot pressing under the conditions of a temperature of 130 to 150 DEG C and the maximum pressure of 2.0 to 3.5MPa. The bamboo-wood composite container base plate with the improved bamboo curtain splint surface layers has the advantages that the improved bamboo curtain splint surface layers prepared from thin bamboo chips having the same width through a novel splicing technology are adopted and thus a container base plate prepared from the bamboo-wood composite container base plate with the improved bamboo curtain splint surface layers is beautiful and has good wear resistance, stable quality and all performance indexes such as intensity and elastic modulus according with technical requirements of the international container industry.

Description

technical field [0001] The invention relates to a bamboo-wood composite container bottom plate with an improved bamboo curtain as the surface layer and a manufacturing method thereof, belonging to the technical field of wood-based panel manufacturing in the wood industry. Background technique [0002] The main load-bearing area of ​​a container is the bottom plate. The container manufacturing industry requires the bottom plate to have high mechanical properties, appearance quality, impact resistance and aging resistance. The existing bamboo-wood composite container floor has two forms: the surface layer of patent ZL 98111153.x is a kind of bamboo-wood composite container floor with impregnated paper and bamboo mat, and the surface layer of another patent ZL 03152841.4 is formed by high-pressure hot pressing A thin layer of high-density bamboo is used as the surface and back layer, and then combined with structural particleboard or poplar veneer as the core for a second he...

AI Technical Summary

Problems solved by technology

The first kind needs to impregnate the paper and bamboo mat in order to obtain a beautiful appearance. The weaving of the bamboo mat requires more labor costs, and the surface quality of the bottom plate is not high; the latter can also achieve the required mechanical properties and acceptable appearance. , but due to the secondary molding, it is necessary to sand the glued surface and apply glue, and then go through secondary hot pressing and compounding, which consumes more energy, materials and labor

These two kinds of bamboo-wood composite container bottom plates have problems such as high cost, which is difficult for container owners to accept.
