Problems solved by technology

[0006] Although the above-mentioned invention uses small-diameter wood, it saves a lot of ordinary logs and expands the use range of artificial wood. It can be made into decorative veneer, wooden load-bearing components and other products through reprocessing according to needs, such as planing or rotary cutting. Low density, low hardness, soft texture, weak strength, easy to crack, seriously affecting the wide use of artificial wood
[0007] The fast-growing wood grows faster, resulting in slightly inferior material and weak corrosion resistance. The veneer often has stains and other defects during use, which limits its application range to a certain extent.

Embodiment 1

[0077] 1. Dyeing treatment of veneer

[0078] 1) Rotate the fast-growing poplar wood into poplar veneers with a thickness of 0.8 mm, select a rotary-cut poplar veneer without holes, skins, and burrs. The moisture content of the veneer is 25-35% in the natural state, and the ;

[0079]2) Add wood staining agent, dyeing auxiliaries (Yuanming powder, penetrating agent, defoamer, etc.) -95°C; then soak the eucalyptus veneer in the dyeing solution of the dyeing machine, dye the veneer, check that the color meets the requirements, take out the veneer, clean and drain the dyeing solution on the surface; among them, according to the difference of the veneer The color is selected, the concentration of the dye solution is 0.3-0.5%, and the dyeing time is 3-8h, which is determined according to the thickness of the veneer. In the embodiment of the invention, the veneer is dyed into American cherry color as an example;

[0080] 3) Dry the filtered veneer with a dryer at a temperature of ...

Embodiment 2

[0115] In the veneer dyeing process, except that the thickness of the veneer is 1.5 mm and the moisture content is 20%, the rest is the same as in Example 1;

[0116] In the process of preparing wood softener, the weights of SMQ-05, penetrant JFC, Pingpingjia O and water are respectively 25kg, 2kg, 6kg and 100kg; the weight of the first batch of water accounts for 30% of the total water weight, and the first heating The temperature of heating up is 50 ℃, and the temperature of heating up for the second time is 70 ℃, all the other are identical with embodiment 1;

[0117] In the process of preparing the impregnation solution, except the weight of raw materials is as follows: the weights of urea, formaldehyde, melamine, polyvinyl alcohol, softener and triethanolamine are 200kg, 610kg, 190kg, 50kg, 30kg, 20kg respectively; the pH of the first stage of the reaction 7.5, the reaction temperature is 90 ℃, the reaction time is 25min, the amount of the first batch of urea accounts for...

Embodiment 3

[0124] In the veneer dyeing process, except that the thickness of the veneer is 1mm and the moisture content is 30%, the rest are the same as in Example 1;

[0125] The process of preparing wood softener is except that the weights of SMQ-05, penetrating agent JFC, flat plus O and water are respectively 15kg, 2kg, 4kg, and 100kg; 1 same;

[0126]In the process of preparing the impregnating solution, except that the weight of the raw materials is as follows: the weights of urea, formaldehyde, melamine, polyvinyl alcohol, softener and triethanolamine are respectively 250kg, 700kg, 250kg, 50kg, 30kg and 10kg; the pH of the first stage of the reaction is 7.8, the reaction temperature is 85°C, the reaction time is 20min, the amount of the first batch of urea accounts for 40% of the total amount of urea; the second stage of the reaction: when the second batch of urea is added, the pH value is 5.0, the reaction temperature is 85°C, the second batch of urea The viscosity of the two-st...

Abstract

The invention relates to technical wood and a manufacture method thereof. The manufacture method comprises the steps of dying and drying eucalyptus and poplar veneers, conducting gum dipping and thickening on the wood veneers by using an ultrasonic vibration method, assembling gum dipping boards, conducting semi-solidification hot-pressing maintaining by using a curve die high-frequency press, conducting square slicing on the technical wood or cutting the technical wood into wood veneers, assembling the wood veneers in the same direction according to needed thickness, and conducting hot pressing and thickening. The thickness of the technical wood veneers or wood square produced by using the manufacture method is as high as 0.8-1.8kg / cm<3>, the thickness of the technical wood is more than 1.5 times of that of common technical wood, a plurality of items of physical and mechanical properties are improved by more than 1.5 times, the technical wood is not easy to crack, product durability improves to more than one time, service life of products is prolonged, and using fields of the products are extended.

Description

technical field [0001] The invention relates to an artificial wood and a preparation method thereof, in particular to an artificial wood which can be used as a surface decoration material and a preparation method thereof. Background technique [0002] At present, with the continuous improvement of people's living standards, people's liking and demand for wood products are increasing. However, with the decreasing resources of global high-grade timber, especially since the implementation of the natural protection forest project, The contradiction between supply and demand of wood is becoming more and more acute, and it is difficult to meet the growing demand by relying on natural wood. At the same time, although my country is currently vigorously developing plantation forests and fast-growing forest tree species, the soft wood produced by plantation forests and fast-growing forests has problems of low decorative value and low physical and mechanical properties, especially the ...
