Composite board of small pieces of bamboo reinforcement, and manufacturing method

Abstract

A composite board containing bamboo skeleton and with high strength, hardness, density and smoothness is prepared through making bamboo strips, drying, coating adhesive, braiding to become bamboo skeleton, rolling on bamboo material, bamboo twigs, leftover of bamboo and wood, or straw or stalk, pulverizing, ageing, drying, sieving, mixing with adhesive, applying it onto said bamboo skeleton, pre-pressing, and hot pressing.

Description

【Technical field】 [0001] The invention relates to a bamboo tendon scrap composite board formed by hot pressing using a bamboo tendon net made of bamboo and scraps such as bamboo and wood processing residues or plant straws and a manufacturing method thereof, belonging to the field of board manufacture. 【Background technique】 [0002] Bamboo has the advantages of high strength, high hardness, rich resources, and can replace wood. Bamboo branches, residual scraps from bamboo processing, or plant straws and other scraps have the characteristics of good filling, uniform expansion, and good sound and heat insulation. Therefore, the two It is widely used in the panel industry. At present, the wood-based panels produced by using bamboo and scrap materials are divided into plywood, laminated board and particle board according to their structure and processing technology. The first two boards use bamboo as the main raw material. The bamboo is split into pieces, coated with glue, and...

AI Technical Summary

Problems solved by technology

The first two boards use bamboo as the main raw material. The bamboo is split into pieces, coated with glue, and hot-pressed into boards. The strength and hardness are good, but there are large raw material consumption, high processing requirements, many internal gaps, low density, and thickness errors. Large and other defects, the number of turnovers is less when used as a building formwork, and its surface is rough, which often cannot meet the flatness requirements of the building surface

The latter uses crushed material as the main raw material, and the crushed material is cold-pressed or hot-pressed into boards. The bamboo consumption is less, the cost is low, the product density is high, and the flatness is high, but there are defects in the mechanical strength of the product, which cannot be used as a building. Performance requirements for formwork, car body panels and other heavily loaded bamboo and wood panels, low reuse rate

It is difficult to increase the density and strength of the bamboo and wood boards produced by the existing methods, and the phenomenon of thickness error is difficult to avoid
