specific Embodiment approach 1

[0011] Specific embodiment 1: The single-slat composite decorative wood of the present embodiment is produced as follows: 1. Fast-growing veneers such as eucalyptus wood are dyed (the veneer thickness is 2.0mm), and then cut into strips. The length of the cut veneer It is 400~1300mm and the width is 5~30mm. 2. Dipping the veneers with melamine modified urea-formaldehyde glue with a concentration of 20-30%, and the proportion of paraffin wax emulsion being 0-1%. The veneers after dipping are pre-dried. 3. The single slats are arranged in parallel in a special mold according to the pre-designed assembly plan. 4. Transport the mold to the cold press and pressurize on all sides, where the upper and lower pressure is 1-5Mpa, the pressure on both sides is 0.1-1Mpa, and the pressure time is 30-120min. 5. Put the cold-pressed and shaped slab into the mold of the hot press for hot pressing. The hot pressing temperature is 100-150℃, the pressure is 4-6Mpa, and the hot pressing time is 1...

specific Embodiment approach 2

[0013] Embodiment 2: The difference between this embodiment and Embodiment 1 is: the veneer used in step 1 can be the bleached, dyed or carbonized single slats of plantation forest fast-growing wood (such as eucalyptus, poplar or pine). The slats can also be natural forest decorative hardwood single slats of different colors or materials. The thickness of the single slat can be 0.5-4.0 mm, the length is more than 15 times the width, and the width is more than 1 time the thickness. The other methods are the same as the first embodiment.

specific Embodiment approach 3

[0014] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the sizing method of the veneer is spraying glue, drenching glue or gluing, and the adhesives used are urea-formaldehyde glue, phenolic glue, melamine glue, isocyanide Acid fat glue, acrylic glue, polyurethane glue, etc. and modified products or compounded products of the several kinds of glues, the solid content of the glue is 15-45%, and 0-20% of flour can be added to the glue according to demand. The curing agent is 0% to 1%, the pigment powder is 0% to 10% (the pigment powder can be a single color, or it can be any combination of several colors). The other methods are the same as the first embodiment.

Abstract

The invention relates to a single-veneer composite decoration board which is a novel decoration board and belongs to a novel technical invention in the filed of wood processing. The single-veneer composite decoration board is formed by adopting the following steps: taking different colors and species of decorative hardwood veneers or artificial fast-growing forest veneers after being bleached, dyed and carbonized as raw materials; cutting the veneers into veneer strips with a certain length and width; gluing, and then arranging and paving and pressing different veneer strips according to proportions as well as colors and textures of decorative hardwood which is designed in advance. Products produced by adopting the method are called single-veneer composite decoration boards in general. Thesingle-veneer composite decoration board has the advantages of low manufacturing cost and wood resources saving and is suitable for a plurality of occasions, such as furniture, indoor decorations, outdoor wood structures, and the like.

Description

(1) Technical field [0001] This invention is a new technical invention in the field of wood processing. (2) Background technology [0002] With the continuous reduction of natural resources of natural forests, people's available decorative hardwoods are becoming more and more limited. Nowadays, wood processing companies have a large waste of materials and low utilization of wood, which has caused a shortage of wood resources. Therefore, there is an urgent need to develop a new type of decorative hardwood, which not only has good decorative properties, is comparable to natural forest decorative hardwood, but also can use wood to a large extent (including natural forest and plantation), and the utilization rate of wood high. [0003] Veneer combination decorative wood is a new type of decorative wood. It is mainly decorated with hardwood veneers of natural forests of different colors and materials or artificial fast-rich forest veneers and their fragments after bleaching, dyeing, an...
