Manufacturing method of remaking light-colored bamboo for outdoors

Abstract

The invention discloses a manufacturing method of remaking light-colored bamboo for outdoors. By softening, rolling and combing the bamboo, the bamboo is prepared into bamboo fiber bundles , impregnation gluing is carried out in a modified phenolic resin adhesive, after the sizing bamboo fiber bundles are uniformly paved into slabs, the bamboo fiber bundles are fed into a hot press for hot press molding. A bamboo chip softening solution is set to a multi-step implementation softening solution, the soaking softening time of a conventional acid solution or a conventional alkali liquor is reduced, by occurring an acylation reaction of glacial acetic acid, dicyclohexylcarbodiimide and maleic anhydride in a cooperating mode, saccharides, starch and protein can be rapidly decomposed by the acylation reaction on one hand, the damage to a cellulose microstructure is reduced and the breakage of a molecular bond of lignin is reduced, the reaction process of the acylation reaction is mild, the color of the fiber bundles is not deepened, the rinsing process is reduced, the bonding performance of the bamboo fiber bundles and the phenolic resin is increased by modifying the phenolic resin adhesive, and the overall mechanical property of a composite plate is increased by adding filler.

Description

technical field

[0001] The invention relates to the technical field of production and application of agricultural by-products, in particular to a production method of light-colored outdoor recombined bamboo. Background technique

[0002] my country is a country rich in bamboo resources. Applying bamboo to the field of composite panels improves the utilization rate of bamboo on the one hand, and provides a composite panel with excellent performance on the other hand. Bamboo wood fiberboard is a high-tech green environmental protection material mainly made of wood cellulose and plant cellulose as basic materials, thermoplastic polymer materials, plastics and processing aids, etc., mixed evenly and then heated and extruded by mold equipment. The new decorative material has both the performance and characteristics of wood and plastic, and is a new type of composite material that can replace wood and plastic. Not only has the characteristics of elegant appearance, but also has g...
