Problems solved by technology

However, with the younger consumers of interior decoration and the continuous improvement of consumption levels and individual needs, the above-mentioned traditional technological wood products can no longer meet the current aesthetic requirements.
[0003] my country's research on technological wood began in Shanghai in the 1980s, and it started relatively late. At present, there is no systematic research on heterogeneous composite technological wood in China, which makes my country's technological wood at the low end of the industry.

[0080] The preparation method of the prepressed formaldehyde-free soybean protein adhesive comprises the following steps:

[0081] S1, proportioned according to the low-temperature pre-cured pre-pressed soybean protein adhesive formula 1;

[0082] S2, adding the polyamide-based epoxy compound into water, ultrasonicating for 3 minutes, adding 20% ​​soybean meal powder, and emulsifying homogeneously for 15 minutes at 40 MPa to obtain the first mixture;

[0083] S3, adding the remaining soybean meal powder into the first mixture, mixing evenly, adding 40% triazine ring-based high-reactivity multifunctional epoxy compound, and reacting at 40°C for 25 minutes to obtain the second mixture;

[0084] S4, adding the remaining triazine ring-based high-reactivity multifunctional epoxy compound into the second mixture, reacting at 70°C for 8 minutes, and cooling down to room temperature to obtain a pre-pressed formaldehyde-free soybean protein adhesive.

Embodiment 1

[0156] According to the pattern design requirements, first recombine the 3-layer Ayousi veneer with a water-based API adhesive with a solid content of 54% and a viscosity of 600mPa·s to obtain the first blank layer, and then coat the two layers of the first blank layer on one side The high-elastic polyurethane adhesive with a viscosity of 250mPa·s (the amount of glue applied is 180g / ㎡) is compounded and pressure-bonded with the aluminum plate after the surface lye degreasing and acid solution neutralization to obtain the second base plate layer, and further The second base layer and the Ayousi veneer coated with urea-formaldehyde resin adhesive on both sides were recombined and recombined. The pressing time was 120 hours, the pressure was 0.6MPa, and the health was cured for 40 days. Finally, the Ayousi veneer and aluminum veneer were produced. Heterogeneous composite technology wood. High-elastic polyurethane adhesive is used for aluminum-wood composites, and high-strength ti...

Abstract

The invention relates to engineered wood, and in particular, relates to aluminum-wood heterogeneous composite engineered wood. The aluminum-wood heterogeneous composite engineered wood sequentially comprises an Ayous veneer layer, more than one group of second blank plate layers and an Ayous veneer layer; the second blank plate layers are each formed by compounding, pressurizing and gluing a firstblank plate layer, an aluminum plate and a second blank plate layer, and the first blank plate layer is formed by recombining more than one Ayous veneer. A preparation method comprises the followingsteps: (1) recombining more than one Ayous veneer by coating a first adhesive to prepare the first blank plate layer; (2) coating the single surface of each of two blank plates A with a second adhesive, and compounding, pressurizing and gluing with a pretreated aluminum plate to obtain the second blank plate layer; (3) compounding, recombining, pressurizing and curing the second blank plate layersand the Ayous veneer coated with a third adhesive, and thus obtaining the aluminum-wood heterogeneous composite engineered wood batten; and (4) slicing. The aluminum-wood heterogeneous composite engineered wood is not prone to cracking and good in stability and has the metallic luster decoration effect.

Description

technical field [0001] The invention relates to a technical wood, in particular to an aluminum-wood heterogeneous composite technical wood. Background technique [0002] With the rapid shrinking of virgin forests in the world, traditional timber exporting countries have raised the export threshold of logs, and my country has also implemented natural forest protection projects. The contradiction between supply and demand of natural precious timber has become increasingly prominent, seriously restricting the construction and decoration, furniture veneer and other industries. healthy growth. Under the above background, scientific and technological wood has developed rapidly. Scientific and technological wood (scientific name: recombined decorative wood) is made of veneer of common tree species as the main raw material, and is manufactured by veneer coloring, lamination, molding and gluing. A wooden decorative material with the texture, pattern, color and other characteristics o...
