Embodiment 1

[0033] (1) Preparation,

[0034] The material preparation process includes: material selection, rotary cutting, defrosting, drying, dipping, drying, cold pressing, sawing and other processes, which belong to the prior art. Process the recombined wood through the above procedures, and saw it into a chord surface width of 20mm, a diameter surface thickness of 5mm, and a length of 1200mm specification recombined wood unit (such as figure 1 shown).

[0035] (2) Diameter surface sizing of recombined wood units

[0036] The diameter surface of the recombined wood unit is sizing, using the glue sizing method, the adhesive used is a water-based polymer isocyanate adhesive, and the sizing amount is controlled at 100 g / m2-105 g / m2 sizing surface layer Apply a quantitative amount of water-based polymer isocyanate adhesive evenly to the radial surface of the recombined wood unit (such as figure 2 shown).

[0037] (3) Dimensional splicing

[0038] Splicing the diameter and surface of...

Abstract

The invention relates to a formaldehyde-free recombined wood integrated material for furniture, and a manufacturing method thereof. Recombined wood units are jointed in diametral planes and are glued in chord planes to form the formaldehyde-free recombined wood integrated material. A gluing agent having a glue layer used in diametral plane jointing is a water based polymer isocyanate gluing agent (API); and a gluing agent having a glue layer used in chord plane gluing is a soy-based protein gluing agent. The invention also provides the manufacturing method of the formaldehyde-free recombined wood integrated material. The manufacturing method includes: material preparation, recombined wood unit diametral plane gluing, diametral plane jointing, single-layer recombined wood jointed plate chord plane gluing, and chord plane assembly gluing; in diameral plane gluing, the used gluing agent is the API; and in single-layer recombined wood jointed plate chord plane gluing, and the used gluing agent is the soy-based protein gluing agent. The non-formaldehyde gluing agents are adopted, the formaldehyde release amount of the recombined wood integrated material is less than 0.1 mg / L, the API used in diametral plane jointing can improve the gluing performance of the plate, and processing energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of recombined wood glulam in the wood-based panel industry and its manufacturing technology, in particular to a formaldehyde-free recombined wood glulam for furniture and a manufacturing method thereof. Background technique [0002] Recombined wood is the main raw material of small-diameter fast-growing forest wood. On the premise of maintaining the original wood fiber arrangement direction and retaining the basic properties of wood, it is a new type of composite wood designed and developed to solve the defects of wood anisotropy and uneven material. Structural materials are an important technical means for efficient value-added utilization of low-quality wood and bamboo materials. Mainly used in floors, furniture, outdoor plank roads, garden buildings and other fields. [0003] Isocyanate and soy-based protein adhesives are non-aldehyde adhesives that have been widely used in plywood, particle board, oriented strand...
