Embodiment 1

[0054] (1) The moso bamboo is decomposed into bamboo bundles with a length of 1000mm and a width of 20mm by using bamboo rolling equipment. Then adopt the conventional kiln drying method to dry the natural color bamboo bundles to a moisture content of 10%;

[0055] (2) Process poplar logs with a length of 1000mm into string-cut veneers with a thickness of 2.0mm by using a string cutting machine, stack the string-cut veneers neatly, and put them directly into a high-temperature and high-pressure treatment tank after being loaded on a wood car. Use the saturated water vapor supplied by the boiler to carbonize the string-cut poplar veneer, control the pressure of the water vapor in the treatment tank at 0.35MPa, carbonize the veneer for 2.5 hours, and carbonize the veneer to brown;

[0056] (3) Use a mesh belt dryer to dry the carbonized poplar veneer to a moisture content of 12%, and then use a veneer shear to cut along the longitudinal direction of the veneer along the grain to...

Embodiment 2

[0066] (1) Adopting bamboo material rolling equipment to decompose moso bamboo into length 1920mm, width is 25mm bamboo bundle, then adopts conventional kiln drying method to dry natural color bamboo bundle to moisture content of 12%;

[0067] (2) Process poplar logs with a length of 1920mm into string-cut veneers with a thickness of 2.5mm by using a string cutting machine, stack the string-cut veneers neatly, and put them directly into a high-temperature and high-pressure treatment tank after loading them on a wood car. Use the saturated water vapor supplied by the boiler to carbonize the string-cut poplar veneer, control the pressure of the water vapor in the treatment tank at 0.4MPa, carbonize the veneer for 1.5 hours, and carbonize the veneer to brown;

[0068] (3) Dry the carbonized poplar veneer to a moisture content of 10% by conventional kiln drying method, and then use a veneer shear to cut along the longitudinal direction of the veneer along the grain, and cut the pop...

Abstract

The invention discloses a method for manufacturing recombined bamboo decorative material, firstly bamboo beams are processed by a defibering treatment, a poplar log is rotary-cut into veneers, poplar veneers are carbonized, dried and sheared, then the bamboo beams and the poplar veneers are dipped with phenolic resin and are processed by second drying treatment, and finally the treatments of cold-pressing, heat curing, balanced modulation and post trimming are carried out, a novel recombined bamboo decorative material with stripe decorative effect, lower density, good dimensional stability and high horizontal bonding strength can be manufactured, during the manufacturing process of the recombined bamboo decorative material, the carbonized poplar veneer strips and the original bamboo beams are evenly mixed, the recombined bamboo decorative material manufactured with the method can be widely applied in the manufacture of floors, interior and exterior decoration materials and engineering structural materials, is practical, and is high in promotion and application value.

Description

technical field [0001] The invention belongs to the technical field of manufacturing decorative materials, in particular to a method for manufacturing recombined bamboo and wood decorative materials. Background technique [0002] my country's bamboo forest area, stock volume, and bamboo industry output value all rank first in the world, and the existing bamboo forest area is about 7.2 million ha 2 , of which Moso bamboo accounts for about 70%. At present, recombined bamboo is the most important bamboo product in my country, and it is widely used in the fields of flooring and furniture manufacturing. [0003] Existing recombined bamboo has a single color (mainly natural color and carbonized color), which is easy to crack when used in an over-dry environment, easy to wrinkle when used in an environment with excessive humidity, and easy to wrinkle when used in an environment with large humidity changes. The main reasons for this defect are: 1) the color of bamboo itself is si...
