Embodiment 1

[0054] (a) Poaching treatment:

[0055] The air-dried poplar wood was sliced ​​into veneers with a thickness of 0.6 mm, boiled in hot water at 60°C for 10 minutes to remove the extracts from the poplar veneers, and then dried to absolute dryness.

[0056] (b) Surface treatment:

[0057] Put the poplar veneer processed through step (a) into a surface treatment solution consisting of 1.0 parts by weight of 3-aminopropyltrimethoxysilane and 9.0 parts by weight of ethanol solution for 5 min, then take out the poplar veneer Dry in the air, after the solvent on the surface of the poplar veneer volatilizes, put it in a drying oven, and dry it at 105°C for 2 hours.

[0058] (c) Surface sensitization and activation treatment:

[0059] Put the poplar veneer after the surface treatment in step (b) into a sensitizer solution composed of 3.0 parts by weight of tin chloride and 7.0 parts by weight of hydrochloric acid solution for 20 seconds, then wash it with water and then dip it in 5.0...

Embodiment 2

[0066] (a) Poaching treatment:

[0067] The air-dried Chinese fir was sliced ​​into shavings with a thickness of 0.5mm, boiled in hot water at 60°C for 15 minutes to remove the extractives in the wood, and then dried to absolute dryness.

[0068] (b) Surface treatment:

[0069] The shavings obtained by step (a) are put into a surface treatment solution composed of 1.0 parts by weight of 3-aminopropyltrimethoxysilane and 9.0 parts by weight of ethanol solution and immersed for 8 minutes, then take out the shavings and dry them in the air. After the solvent on the surface of the shavings evaporated, put them in a drying oven and dry them at 103°C for 1 hour.

[0070] (c) Surface sensitization and activation treatment:

[0071] Put the shavings after the surface treatment in step (b) into a sensitizer solution composed of 3.0 parts by weight of tin chloride and 7.0 parts by weight of hydrochloric acid solution for 40 seconds, then wash them with water and then immerse them in a...

Embodiment 3

[0080] (a) Poaching treatment:

[0081] Air-dried poplar wood was sliced ​​into veneers with a thickness of 0.7mm, boiled in hot water at 70°C for 5 minutes to remove extracts from the poplar veneers, and then dried to absolute dryness.

[0082] (b) Surface treatment:

[0083] Put the poplar veneer processed through step (a) into a surface treatment liquid composed of 1.0 parts by weight of trimethoxysilane and 9.0 parts by weight of ethanol solution for 10 minutes, then take out the poplar veneer and cool it in the air After the solvent on the surface of the poplar veneer volatilizes, put it in a drying oven and dry it at 107°C for 2.5 hours.

[0084] (c) Surface sensitization and activation treatment:

Abstract

The present invention provides one kind of chemical plating liquid composition for wooden material and the process of preparing electromagnetic shielding material on the surface of wooden material. The chemical plating liquid composition consists of metal salt 2.0-7.0 weight portions and complexing agent 3.0-6.0 weight portions. The chemical plating process includes the steps of water boiling of wooden material, surface treating, surface sensitizing and activating, reducing and surface chemical plating. The obtained electromagnetic shielding material has an electromagnetic shielding effectiveness in the frequency range of 5 KHz-1500 MHz up to 31.8dB-51.4dB. The present invention can raise the surface decoration effect of wooden material, endows wooden material with conducting performance and electronic shielding performance, raise the application value and use safety of wooden material.

Description

technical field [0001] The invention relates to a composition for surface chemical plating solution, in particular to a composition for surface chemical plating solution of wooden materials and a method for preparing wooden electromagnetic shielding material using the composition. Background technique [0002] Wood is widely used in every link of national economic development, from people's daily living utensils, furniture, interior decoration and furnishing components to packaging supplies, transportation tools, sports equipment to large buildings, wood plays an important role. The use of wood has witnessed the development of human civilization. [0003] As the most typical biocomposite material, wood has the advantages of large strength-to-weight ratio, good heat insulation, sound insulation, low processing energy consumption, less environmental pollution, renewable, and natural degradation. However, wood also has some disadvantages, such as properties Large variability, ...
