Abstract

The invention relates to a novel laminated wood. The novel laminated wood comprises a fir core veneer layer positioned at a central position, two cotton wood veneer layers which are respectively adhered on both upper and lower surfaces of the fir core veneer layer and two laminated wood layers which are adhered on the other surface of the two cotton wood veneer layers respectively, wherein the directions of wood grains of every two adjacent two veneer layers are vertical to each other. The invention also relates to a method for preparing the laminated wood. The method comprises the steps of producing the laminated wood layers, producing the cotton wood veneer layers, producing the fir core veneer layer, sizing, laminating, molding and the like. The novel laminated wood has the advantages of good stability, low cost and environment protection and can be widely used for preparing indoor decoration, such as furnitures, floors, door panels, ceilings and the like.

Description

technical field [0001] The invention belongs to the wood processing industry, and in particular relates to a novel glued wood and a manufacturing method thereof. Background technique [0002] Glulam, also known as finger-jointed lumber or laminated lumber, is a material formed by gluing boards and small squares whose fiber directions are basically parallel in the length, width and thickness directions. Glulam preparation has been disclosed in the prior art. CN101115599 (2008-01-30) discloses a veneer manufacturing method, comprising: (i) gluing plate-shaped flat wood chips into strip-shaped wood blocks with an adhesive; (ii) soaking the strip-shaped wood blocks and / or or heat treatment; (iii) cutting the strips into veneers; (iv) drying the veneers obtained in step (iii) until their moisture content is lower than the fiber saturation point. CN101259627 (2008-09-10) also discloses a method for preparing laminated lumber, which includes assembling graded Chinese fir, making ...
