Embossing preparation process of wood for solid-wood doors and windows

Abstract

The invention discloses an embossing preparation process of wood for solid-wood doors and windows. The machining process comprises the steps of: firstly, machining a material according to size, wherein a log is sawn into a base material according to the discharging size; secondly, carrying out wet-humid softening on the material, wherein the base material is soaked in hot water and then dried to control the water content of the base material; thirdly, modifying the material, wherein the treated base material is immersed in a modifying agent for being subjected to dipping treatment to obtain a modified material; fourthly, dewatering the modified material, wherein the modified material is dewatered in an environment with low temperature so that the water content is lowered; and fifthly, mould-pressing the modified material and sizing resin, wherein the modified material is hot-pressed in a metal hot-pressing mould. By adopting the mode, according to the embossing preparation process of wood for solid-wood doors and windows, the solid-wood doors and windows are prepared by using a wood fiber cell lossless mould pressing method through modifying the wood, and are endowed with excellent dimensional stability, crack resistance, high density, high surface hardness, structure property and the like so as to be used for replacing and be superior to a conventional product.

Description

technical field [0001] The invention relates to the field of wood processing, in particular to a wood embossing preparation process for solid wood doors and windows. Background technique [0002] During the milling process of the board and the generation of three-dimensional patterns, the transverse fibers of the wood will be cut off in large quantities, so that the exposed cell cavity and cell wall are easy to absorb moisture, resulting in unstable material dimensions and easy deformation of the product. Poor, when the external environment changes greatly, the material is easy to crack. At the same time, the exposed part of the wood has a relatively large cross-section, and a large number of large-sized tube holes and cell cavities will cause excessive penetration of the finishing paint and oil, poor finishing effect, and affect the appearance.
