Preparation method of large-sized solid wood composite board and prepared solid wood composite board

Abstract

The invention relates to a preparation method of a large-sized solid wood composite board. The preparation method comprises the following steps that a dried solid wood large board is stamped into small wood strips with the same thickness and the same or similar width; the small wood strips are made into equal-length wood strips with the same length, and surface treatment is conducted; the equal-length wood strips are transversely spliced into a large-sized wide board; a surface material is compounded on the combined and machined large-sized wide board, specialized putty is adopted as a coatingmaterial adopted in the compounding process, a coating layer is formed on a surface layer of the large-sized wide board through the specialized putty, and drying and curing are conducted after compounding; and lastly, double-faced sanding operation and flushing construction are conducted, and a finished product is prepared. According to the preparation method and the prepared solid wood compositeboard, the defects that in an existing solid wood large board and other machining modes, deformation is prone to occurring, and the outturn percentage is low are overcome, new functions brought by the surface material are highlighted after the deformation problem is solved, and the solid wood-based new material machining and applying new view is achieved.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a preparation method of a solid wood composite material and a novel large-scale solid wood composite material prepared. Background technique [0002] As a building decoration material, solid wood panels have always been the most ideal choice. Solid wood panels have the effect of environmental protection and health. They can not only keep warm but also have the effect of being close to nature, which is beneficial to people's physical and mental health. However, solid wood boards have certain disadvantages as building materials and furniture materials, which greatly limit their application. Since solid wood panels are naturally grown from trees, there are endogenous growth stresses caused by problems such as scarring, annual rings, windward, and sunny, and the accumulation of growth stress is most likely to cause defects such as deformation and cracking in the later stage.
