s2, dissolving acrylic and a polymer in a solvent (different from the solvent in the anti-static layer, chloroform or carbon tetrachloride is adopted), and pouring and drying to obtain a transparent acrylic plate layer;
s3, weighing raw materials of the anti-static layer according to the parts by weight, mixing the raw materials into slurry, uniformly coating the slurry on a PET film, and drying the PET film;
s4, arranging an adhesive layer on the other side of the PET film, and adhering the adhesive layer to one side of the transparent acrylic plate layer;
and S5, bonding the other side of the transparent acrylic plate layer with the bottom layer through the adhesive layer.
Among this application technical scheme, one side on transparent ya keli board layer is pasted and is had the PET membrane, and PET epimembranal coating has the antistatic backing, also has the antistatic agent in the viscose layer simultaneously to make the ya keli board have good antistatic performance. The fiber filler in the antistatic layer enables the antistatic layer to have certain toughness, the surface of the antistatic layer is effectively prevented from cracking, the antistatic layer is guaranteed to have good antistatic performance all the time, and meanwhile, the anionic surfactant in the antistatic layer enables the antistatic layer to have better chemical stability, so that the corrosion resistance of the antistatic layer is effectively improved.
The transparent acrylic plate layer is formed by compounding acrylic, methyl methacrylate monomers and nano tannic acid, so that the acrylic plate has good oxidation resistance, antibacterial property and ultraviolet shielding property.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
