Embodiment 1

[0028] Take the product of 1.2mm oak veneer as an example. The wood veneer and the base material of corresponding specifications have a moisture content of 10-20%; after gluing, veneering, cold pressing for 60 minutes, hot pressing, and then balance and health preservation, after 80-85 hours, the raw material is cut and sanded to form a plain board; then Carry out molding and groove treatment; then apply primer and topcoat; finally, the finished product is packaged and rolled off the assembly line.

Embodiment 2

[0030] Take the product of 1.2mm oak veneer as an example. The wood veneer and the substrate of corresponding specifications have a moisture content of 10-20%; after gluing, veneering, cold pressing, and then hot-pressing process, the hot-pressing temperature is controlled between 80-90 °C, and the hot-pressing time is controlled at 150-150 °C. After 200s, heat pressing and then carry out balanced health preservation. After 80-85 hours, carry out material cutting and sanding to form a plain board; then carry out molding and groove processing; then apply primer and topcoat; finally, the finished product is packaged and rolled off the assembly line.

Embodiment 3

[0032] Take the product of 1.2mm oak veneer as an example. The veneer and the base material of corresponding specifications have a moisture content of 10-20%; after gluing, veneering, cold pressing for 60 minutes, and then hot pressing, the pressure is kept at a unit pressure of 0.8-1.0 MPa, and after hot pressing, carry out 10-30s Hold the pressure, release the pressure after holding the pressure, and then enter the balanced health preservation stage. After 80-85 hours, carry out cutting and sanding to form a plain board; then carry out molding and groove processing; apply primer and topcoat; finally carry out Finished product packaging off the assembly line.

Abstract

The invention belongs to the technical field of building materials, and relates to a production process of a multilayer solid wood composite floor with a high-water-content wood veneer veneering. The process comprises the following steps of gluing and veneering, cold pressing, hot pressing, balanced curing, cutting, primer coating, forming, finish coating and finished product packaging, in the gluing and veneering process, the surface of a criss-cross multilayer board base material is coated with melamine-modified urea resin glue, the single-face glue applying amount is 80-130 g / m < 2 >, a layer of hard broadleaf wood veneer / wood veneer with the high water content is pasted after glue applying, the water content ranges from 10% to 20%, and the thickness ranges from 0.6 mm to 2.0 mm. Adjusting and improving are carried out on an existing production process, the production process is simple, the cost is low, dry energy is saved, the moisture return phenomenon caused by large rainwater, water content difference of various regions and the like in the transportation process is avoided, the high-water-content wood veneer is fully utilized, and existing forest resources are saved; and the prepared floor has no problems of buckling deformation, tile bending or cracking and the like, and the physical and mechanical properties meet the requirements of various indexes.

Description

technical field [0001] The invention belongs to the technical field of building materials and relates to the production of solid wood floors, in particular to a production process for multi-layer solid wood composite floors with high moisture content veneer veneers. Background technique [0002] Multi-layer solid wood composite flooring is made of natural precious tree species veneer (wood veneer) of different thicknesses as the surface layer, plywood made of solid wood veneer with criss-cross textures as the base material, coated with high-performance, high wear-resistant, high-environmental protection UV It is made of special paint for light-cured floors, and is widely used in the home building materials industry. However, with the shortage of forest resources, the resource limitation of solid wood composite flooring increases, especially the hard broad-leaved tree species selected from decades or even hundreds of years, and the available resources decrease rapidly. Raw m...
