Wood composite flooring needle, hardwood tree rift sawing plaga surfacing material decorative sheet and production method

Abstract

The invention provides a wood composite floor coniferous and broadleaf tree walk cutting lining decorative sheet and producing method. The decorative sheet is composed of peeler log veneer as core material and scientific wood sliced diameter-cut veneer which is sticked to the surface of the core material. The said method comprises a process of producing the scientific wood and a process of compression cementing using scientific wood sliced diameter-cut veneer as facing. On compressing, the method uses plastic film isolation and multilayer overlap compression. The batch products are obtained by applying pressure for one time. The invention can obtain true wood composite floor coniferous and broadleaf tree walk cutting lining decorative sheet with uniform and beautiful texture. The log of common diameter class is used to extend the range of sorting. The sliced scientific wood veneer is used, so that the quality raw material utilization factor is high and increased by tens times than using direct saw cutting plate. The said invention fundamentally solves the economical efficiency of the said products and makes the products suitable for the social consumption level.

Description

technical field [0001] The invention belongs to the field of wood processing. Background technique [0002] In order to improve the utilization rate of hard and clear needles, soft and hard miscellaneous woods in broad-leaved trees and minimize the deformation of the floor during use, in recent years, solid wood floors are mostly composite structures. The upper fabric of composite flooring mostly uses high-quality hard miscellaneous wood, and the lower part of the fabric uses soft wood to achieve the purpose of saving high-quality decorative wood. For a long time, the floor with a quarter-sawn surface has been the first choice for most layers. However, the yield of quarter-sawn boards obtained by cutting logs is low. Coupled with natural defects such as color difference and tree knots, the utilization rate of logs is generally only one fifth. This is extremely inconsistent with the current situation of timber shortage. Later, the log was first rotary cut, and then the rot...
