Embodiment Construction

[0051] A method for manufacturing a bamboo long fiber composite profile of the present invention will be described in detail below in conjunction with the implementation.

[0052] The manufacturing method of the recombined bamboo product whose specification is 2500×200×200mm, its production steps are:

[0053] (1) Raw material preparation

[0054] A, Preparation of Bamboo Long Fiber Reinforcement

[0055] A-1, cut bamboo into 2500mm long bamboo tubes, then cut it into bamboo slices with a width of 40mm with a collider, and remove green (bamboo skin) and yellow (bamboo skin) of bamboo slices with a steel brush and a rolling machine. The innermost part, the bamboo cavity wall) part and rolled into bundles of bamboo fibers;

[0056] A-2, place the bundle-shaped bamboo fibers after removing green and yellowing in 0.8% sodium hydroxide solution, heat to 80°C, soak for 2 hours and then soak in clean water for half an hour to obtain hemicellulose and fruit Bundle-shaped bamboo fib...

Abstract

The invention relates to a method for manufacturing a bamboo macrofiber composite material. Bunchy bamboo fibers of which the green and yellow are removed are taken as raw materials and dipped with a water soluble phenol formaldehyde adhesive, and the production steps comprise material preparation (comprising the preparation of bamboo macrofiber reinforcement and a water soluble phenol formaldehyde resin matrix), adhesive dipping, extraction, warm-pressing, curing and post curing. The method has the advantages that: (1) the method has reasonable process, strong production continuity, high efficiency, low energy consumption, and no environmental pollution; (2) the manufactured bamboo macrofiber composite material has no mold and no crack, and has the density between 0.9 and 1.3g / cm<3>, thehardness between 60 and 150MPa, the static bending strength between 140 and 160MPa, the water-absorbing expansion rate between 0.3 and 2 percent, the surface wear resistance between 0.04 and 0.09g / 100r, and the formaldehyde emission between 0.1 and 0.4mg / L; and (3) the invention provides a more positive production technique for reasonably utilizing the bamboo resources, so that the reconstituted bamboo timber application prospect is better.

Description

【Technical field】 [0001] The invention relates to the technical field of processing wood or similar materials, in particular to the manufacture of wood-based panels, in particular to a method for making bamboo long-fiber composite profiles using bamboo. 【Background technique】 [0002] Due to the reduction of forest resources and restrictions on deforestation, timber resources are becoming increasingly tense. In order to alleviate the tension of timber resources and achieve better environmental protection, it is feasible to use bamboo with a short growth cycle and good material properties to replace timber. [0003] At present, various products made of bamboo and new production technologies emerge in an endless stream. The emergence of recombinant bamboo has brought the utilization level of bamboo to a new height. Existing recombined bamboo technology has the disclosed "bamboo material recombined and reinforced molding method" in Chinese patent ZL99117809.2, which is to spli...
