Method of preparing bamboo wood complementary composite material

Abstract

The present invention belongs to the technical field of artifical boards and composite materials. The present invention applies the following processing steps: the collection of bamboo materials, the processing of bamboo culms, the slicing of bamboo strips, the processing of bamboo filament, the processing of a bamboo filament curtain, the glue dipping of the bamboo filament curtain, the glue trickling and drying of the glue-dipped bamboo filament curtain, the peeling and slicing of wood veneers, the removal of wood scars, the production of glulam, the glue dipping and drying of the wood veneers, unidirectional bamboo-wood laminating assembly, pressing, etc. By utilizing the characteristics of bamboo and wood and the performance complementation of bamboo as the main material and wood as the auxiliary material, a high-quality composite material with an excellent performance and without inside defects is produced.

Description

Technical field: [0001] The invention belongs to the technical field of wood-based panels and composite materials. Background technique: [0002] Bamboo is a renewable natural material with excellent performance, and the outer bamboo has good performance. However, the bamboo is thin-walled, hollow, and irregularly elliptical cone-shaped with a sharp point, and the radial properties of the bamboo are very different, and the external and internal properties of the bamboo are very different. Bamboo can be made into different processing units, including bamboo tubes, bamboo strips, bamboo slices (bamboo strips), bamboo filaments, vascular bundles and bamboo fibers. It is difficult to directly make high-performance structural materials from bamboo tubes. The main reason is that the geometric shape of the bamboo tube is irregular and the connection is difficult. The second is that the vascular bundles are densely distributed on the outside of the bamboo tube, and the dry shrink...

Problems solved by technology

It is difficult to directly make high-performance structural materials from bamboo tubes

The main reason is that the geometric shape of the bamboo tube is irregular and the connection is difficult

Second, the distribution of vascular bundles on the outside of the bamboo tube is dense, and the dry shrinkage and wet expansion rate is high

However, it is difficult to accurately locate the direction and position of the bamboo silk, and there will be a certain number of voids inside the bamboo silk composite material, which will affect the performance of the material.
