Problems solved by technology

[0003] In the prior art, as a high-strength flat plate made of wood fiber and thermosetting resin through high-pressure polymerization, the anti-folding board has an obvious laminated structure; static electricity is a kind of charge in a static state. Static electricity is formed when an object is on or on the surface; charge transfer will occur when an object with static electricity touches a zero potential object (grounded object) or an object with a potential difference with it, which is the phenomenon of spark discharge that we see every day. The interference can still be overcome. The existing anti-static board lacks special measures in terms of anti-static. However, in places with high requirements such as operating rooms and laboratories, the anti-static performance of the anti-static board cannot meet the requirements, resulting in poor use. limit

Embodiment 1

[0021] Such as figure 1 As shown, the antistatic and anti-folding board of this embodiment includes a substrate 1, and the outside of the substrate 1 is coated with a decorative paper 2 treated with impregnated resin. Cured coating 3, the electron beam cured coating 3 is composed of the following raw materials by weight percentage: 30% polyester acrylic acid, 19% phenolic acrylic acid, 15% co-crosslinking agent, 15% hexanediol diacrylate, flame retardant 4%, coupling agent 0.5%, leveling agent 0.5%, nano-silver powder 10%, dispersant 1%, antistatic agent 5%, the above materials are stirred and mixed to obtain electron beam curing coating resin, wherein the co-crosslinking agent is Trimethylolpropane Triacrylate.

Embodiment 2

[0023] The manufacture method of the antistatic anti-fold special board of embodiment 1, comprises the steps:

[0024] A. Electron beam curing coating resin preparation: Add the following raw materials into the mixer by weight percentage, including polyester acrylic acid 30%, phenolic acrylic acid 19%, co-crosslinking agent 15%, hexanediol diacrylate 15%, barrier Combustion agent 4%, coupling agent 0.5%, leveling agent 0.5%, nano silver powder 10%, dispersant 1%, antistatic agent 5%, start the agitator and heat to 50 ° C, stir evenly, vacuumize, and obtain electrons Beam cured coating resin solution.

[0025] B. Impregnate the decorative paper with resin, dry and rewind to ensure that the obtained decorative paper has a uniform weight, a smooth surface, and the light fastness rating of the printing ink is not less than 6.

[0026] C. Glue coating and curing. Apply the electron beam curing coating resin in step A to the impregnated decorative paper obtained in step B by rollin...

Embodiment 3

[0035] A kind of manufacturing method of antistatic anti-fold special board, on the basis of embodiment 2, there is following difference in the manufacturing method of present embodiment:

[0036] In step B, the grammage of the decorative paper before impregnation is 130 g / m2, the amount of glue applied during impregnation is 80 g / m2, the volatile matter is 3%, and the light fastness rating of the printing ink is grade 7 to ensure uniform impregnation of the decorative paper.

[0037] In step B, the impregnated resin is a mixture of melamine-formaldehyde resin and phenol-formaldehyde resin, wherein the mass percentage of melamine-formaldehyde resin is 50%, and the mass percentage of phenol-formaldehyde resin is 50%, so as to ensure the decoration after impregnation The paper retains its toughness while retaining its affinity for electron beam cured coating resins.

[0038]In step C, the coating thickness is 0.15 mm; in step D, the substrate is made of fiberboard substrate impr...

Abstract

The invention relates to an antistatic compact laminate and a preparation method thereof. The antistatic compact laminate comprises a base plate, decorative paper treated by impregnating resin coats the base plate, and electron beam curing coatings coat surfaces of the decorative paper. Since the decorative paper on surfaces of the compact laminate is coated with the electron beam curing coatings,electron beam curing coating resin comprise nanometer silver powder and an antistatic agent, the antistatic agent is a commercialized permanent high-molecular antistatic agent, and the electron beamcuring coating resin is prepared by blending the commercialized permanent high-molecular antistatic agent with the low-cost nanometer silver powder by physical blending, the antistatic performance ofthe compact laminate is improved substantially.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to an antistatic and anti-folding board and a preparation method thereof. Background technique [0002] Anti-fold special board has excellent stability and is easy to clean and maintain, so it has a wide range of applications.
