Embodiment 1

[0024] A wood-based panel with electromagnetic shielding function, its structure is that the raw materials include poplar veneer and aniline prepolymer, wherein the aniline prepolymer is in-situ polymerized into polyaniline in the poplar veneer, and the wood-based panel has a double-layer structure , wherein the surface layer is poplar veneer containing polyaniline; the bottom layer is wood plywood.

[0025] Its manufacturing method comprises the following process steps:

[0026] 1) The surface layer is to vacuumize the poplar veneer with a thickness of 1.2mm for 30 minutes, mix the aniline monomer and phosphoric acid solution at 0~5°C (mass ratio is 1:1), and then under vacuum pressure Immerse the aniline prepolymer into the wood / bamboo veneer for 25 minutes, then slowly drop the ammonium persulfate oxidant (1.5:1 mass ratio to the aniline monomer) to make the aniline monomer In-situ polymerization in an ice bath environment for 6 hours, take out the test piece, wash the unr...

Embodiment 2

[0033] A wood-based panel with electromagnetic shielding function, its structure is that the raw materials include rotary-cut bamboo veneer and aniline prepolymer, wherein the aniline prepolymer is polymerized into polyaniline in-situ in the rotary-cut bamboo veneer, and the wood-based panel has a double Layer structure, in which the surface layer is rotary cut bamboo veneer containing polyaniline; the bottom layer is medium density fiberboard.

[0034] Its manufacturing method comprises the following process steps:

[0035] 1) The surface layer is to vacuumize the rotary-cut bamboo veneer with a thickness of 0.6mm for 20 minutes, mix the aniline monomer with the phosphoric acid solution at 0-5°C (mass ratio is 1:1.2), and Immerse the aniline prepolymer into the rotary-cut bamboo veneer for 30 minutes, and then slowly drop in the ammonium persulfate oxidant (the mass ratio of aniline monomer is 1.3:1), so that the aniline monomer is at 0~5℃ In-situ polymerization reaction in ...

Embodiment 3

[0042] A wood-based panel with electromagnetic shielding function, its structure is that the raw materials include beech veneer and aniline prepolymer, wherein the aniline prepolymer is in-situ polymerized into polyaniline in the beech veneer, and the wood-based panel has a double-layer structure, wherein Top ply beech micro-veneer with polyaniline; bottom ply particleboard.

[0043] Its manufacturing method comprises the following process steps:

[0044] 1) The surface layer is made of beech veneer with a thickness of 0.5mm and vacuumized for 15 minutes. Mix the aniline monomer and phosphoric acid solution at 0~5°C (mass ratio is 1:1), and then put it under vacuum pressure. The aniline prepolymer was impregnated into the rotary-cut bamboo veneer for 30 minutes, and then ammonium persulfate oxidant (mass ratio of 1.5:1 to aniline monomer) was slowly dropped to make the aniline monomer In-situ polymerization reaction in bath environment for 6 hours, take out the test piece, wa...

Abstract

The invention discloses an artificial plate with an electromagnetic shielding function and a manufacturing method thereof. The artificial plate is prepared from a wooden / bamboo single plate and an aniline prepolymer, wherein the aniline prepolymer is subjected to in-situ polymerization in a wooden / bamboo single plate substrate to form conductive polyaniline macromolecules and adopts a double-layer structure; a surface layer is a polyaniline-containing wooden / bamboo single plate, and a bottom layer adopts a wooden plywood, a medium (high)-density fiber plate or a chipboard. The artificial plate has the advantages that characteristics of wood and polyaniline are fully used; the wooden artificial plate is used as a base material, and a wooden / bamboo material with the polyaniline is laminated on the surface layer of the base material, so that the novel wooden artificial plate with a conductive function is prepared. The artificial plate has the self performance feature of the wooden material, and the electromagnetic shielding efficiency of the artificial plate is up to 32.78-49.35dB under a shielding efficiency test within a frequency range of 5-1,500KHz according to a military standard (GB-SJ20524-1995) of the electronic industry in China.

Description

technical field [0001] The invention relates to a man-made panel with electromagnetic shielding function and a manufacturing method thereof, belonging to the technical field of manufacturing electromagnetic shielding materials.
