In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.

An anti-aging PVC decorative plate comprises a substrate 1, wherein one side of the substrate 1 is provided with a splicing groove 2, a fixed groove 4 is arranged inside the splicing groove 2, the other side of the substrate 1 is provided with a splicing convex edge 3, and the lower end of the splicing convex edge 3 is provided with a fixed convex edge 5; the upper surface of base plate 1 is equipped with

printing layer

6, 6 upper surfaces of printing layer are equipped with foaming layer 7, the upper surface of foaming layer 7 is equipped with protective layer 8, the upper surface of protective layer 8 is equipped with glass steel lacquer layer 9.

Specifically, adjacent two base plate 1 the concatenation bead 3 card is gone into behind the splice groove 2, fixed bead 5 embedding in fixed recess 4, alright realize the connection of two PVC decorative boards like this. Further preferably, the bottom 21 of the splicing groove 2 is arc-shaped; outer tip 31 of concatenation bead 3 is circular-arc, and circular-arc setting more does benefit to the smooth and easy concatenation between the PVC decorative board, avoids comparatively sharp acute angle fish tail or bumps other article simultaneously.

Preferably, the material of the glass fiber reinforced plastic paint layer 11 is unsaturated resin paint, and the material of the protective layer 8 is UV glue, so that the glass fiber reinforced plastic paint is more environment-friendly, and the release of toxic and harmful gases is reduced.

The production method of the aging-resistant PVC decorative board comprises the following steps

Processing a substrate: the coating comprises the following components, by weight, 4-6 parts of inorganic fiber, 100 parts of PVC, 90-95 parts of ethylene acrylate, 12-15 parts of starch modified bentonite, 4-6 parts of formyl peroxide, 2-4 parts of titanium dioxide, 7-9 parts of calcium oxide, 3-6 parts of alkyd resin, 15-26 parts of magnesium carbonate, 4-5 parts of dimethyl silicone oil, 3-6 parts of anion powder, 5-7 parts of paraffin, 2.3-4.2 parts of barium stearate, 1.1-1.8 parts of calcium stearate, 3-5 parts of a release agent and 2.1-2.4 parts of a coloring agent; vacuum heat treatment: performing heat treatment in vacuum medium with vacuum degree of 0.9Pa at 200 deg.C for 30min, and naturally cooling; molding: placing the mixture after heat treatment and cooling into a mold, placing the mold into a heat preservation box at 50-60 ℃, pressurizing by a press machine at 4-5Mpa, preserving heat for 3h, demolding to obtain a substrate, ventilating and airing the substrate, controlling the airing temperature at 30-40 ℃, and airing for 45 h;
