Problems solved by technology

But the disadvantages are: the former method is not effective because the wood size is too large and the resin impregnation is uneven; the latter two methods have the defect that the material is processed too finely and too small, and as a result, the final board completely loses the natural texture of the wood and loses its natural texture. The aesthetic feeling and economic value are seriously damaged, and the processing time is long, the amount of sizing is large, and the cost is high

Abstract

The invention discloses a method of using a poplar or the poplar and paulownia to manufacture imitated precious wood. The method comprises the steps of force drying, dyeing, vacuum pressing and dipping, thermo-compression forming and the like. In the method, a paulownia single plate and a poplar bundle are dyed into a required color and then are assorted and combined, and alternatively different polar bundles dyed into different colors are assorted and combined according to the different colors; a traditional scientific method that when the wood is manufactured, large-warp wood is rotationally cut into specification single plates, then drying, dyeing, gluing and thermo-compression sizing are conducted, so that the imitated precious wood is manufactured is changed. The method makes good use of waste materials, and the use rate of the wood can reach more than 90%.

Description

[0001] technical field [0002] The invention relates to a method for manufacturing imitation precious wood, in particular to a method for manufacturing imitation precious wood by using poplar wood bundles or poplar wood bundles and paulownia veneer. Background technique [0003] Paulownia and poplar are important short-period fast-growing industrial timber tree species in my country. They have a wide planting area and a large stock volume, and have made important contributions to alleviating the tension between my country's timber supply and demand. However, due to their low density, poor hardness, and loose material And other mechanical properties defects, so that its application in furniture manufacturing, decoration materials, etc. is limited. The general practice at home and abroad is to impregnate large-scale paulownia, poplar boards or squares with resin, then vacuum impregnate, and then heat-press to shape, or make wood strips with a thickness of 0.5-5mm and a width o...
