A kind of method for preparing antique wooden material with high strength

Abstract

The invention discloses a method for preparing antique wood material with high strength. The method comprises the following steps that step 1: heating a wood material to 50-80 DEG C; step 2: cooling the wood material to a nano-silica solution with a concentration of 30-50% and heating the wood material to 40-90 DEG C; step 3: rinsing a pretreated wooden material veneer to remove the nano-silica solution remaining on the surface of the wood material; and step 4: placing the rinsed wooden material veneer into a metal salt containing solution to carry out the reaction to obtain the wood material.The beneficial effects of the method for preparing antique wood material with high strength are that on one hand, the gap between the wood material is filled, and on the other hand, the cross-linkingreaction can bond the fibers of the wood material together, thereby improving the strength of the whole wood material; and due to the reaction of the metal salt containing solution, the wood materialcan be discolored, and then the interior of the wood material can be further discolored. The color change process is not just on the surface of the wood material.

Description

technical field [0001] The invention relates to the technical field of wood material processing, in particular to a method for preparing antique wood materials with high strength. Background technique [0002] Chinese ancient wooden structure architecture is an important part of our country's cultural heritage, and it is also a precious cultural heritage shared by all mankind. However, limited by the natural properties of wooden materials, wooden structure buildings are easily damaged by varying degrees of aging, decay, etc. due to factors such as wind, sun, and microbial corrosion. It is of great historical significance to cherish and protect ancient wooden structures, and it is imperative to repair and strengthen ancient wooden structures. CN1043462A and CN1526527A respectively disclose two methods of antique wood materials: "process method for antique treatment of wood product surface" and "process method for antique wood material". To achieve the purpose of making old ...

CN1043462A and CN1526527A respectively disclose two methods of antique wood materials: "process method for antique treatment of wood product surface" and "process method for antique wood material". To achieve the purpose of making old and antique, this kind of method has the disadvantages that the surface of wooden materials is easily deformed by heat and the treatment effect varies greatly

CN104441152B discloses "a treatment method for antique wooden materials", which is to prepare a layer of antique coating through processes such as surface treatment of wooden materials, painting, and sizing. Although this method has less damage to the structure of wooden materials, the processed wooden materials The anti-corrosion performance of the surface is good, but the antique coating is easy to produce a large contrast with the repaired part, which affects its repair effect

[0003] And these methods will have an impact on the wood material itself, causing its mechanical properties and strength to drop significantly
