Production method of stabilized solid wood composite floor with buffer layer

Abstract

The invention discloses a production method of a stabilized solid wood composite floor with a buffer layer, comprising four steps of preparing materials, gluing, preparing blanks and hot pressing. The composite floor comprises a surface layer (1), a core layer (3) and a base layer (4); the buffer layer (2) is arranged between the surface layer (1) and the core layer (3); the wood grains of three layers of the surface layer (1), the buffer layer (2) and the base layer (4) are all arranged longitudinally consistently; and only the wood grains of the core layer (3) which is formed by parallelly arranged rectangular battens (5) at intervals are laterally distributed. The composite floor produced by the method is specially used for the floor or the wall plate to decorate the house, compared with the general three-layer solid composite floor, because of adding the buffer layer, the cracking phenomena that wavy stripes and the surface-layer wood appear in the original three-layer solid composite plate are improved; a continuous binding interface is formed on the surface of the core layer; the surface-layer binding area is increased; the bonding strength is improved; and the deformation of the surface-layer wood is impeded, thus the stability of the floor is improved.

Description

technical field [0001] The invention relates to a production method of a laminated product, in particular to a production method of a solid wood composite floor formed by laminating and gluing wooden boards or strips with a buffer layer. Background technique [0002] The three-layer solid wood composite floor that is more popular with consumers and therefore commonly used is made of a hard solid wood panel layer, a core layer of medium-soft solid wood strips, and a veneer bottom layer, which are hot-pressed with glue. Flooring has similar advantages, such as wear-resistant surface and beautiful wood grain. Because natural defects such as knots and boreholes are eliminated during production, it is cleaner and more beautiful, and the cost is low, and high-quality precious wood can be rationally used, so it is very popular and widely used. However, due to the inconsistency of the materials of the three layers and the asymmetry of the structure, the floor inevitably has problem...

Problems solved by technology

There are also articles introducing the use of coniferous wood with small deformation stress for the bottom plate, some advocate increasing the curing time of each layer of blanks, and some suggest changing the vertical asymmetric structure of the upper, middle and lower layers into a symmetrical structure to balance the stress, etc. However, no relevant information on the technical solution of increasing the buffer layer to improve stability has been retrieved
