Description

Technical Field

[0001] The invention relates to the technical field of building materials, in particular to a polypropylene imitation stone composite wallboard and a preparation method thereof. Background Art

[0002] Currently, there are many decorative materials available on the market for interior and exterior walls, including veneers, coatings, and more. Veneers, such as marble slabs, granite slabs, ceramic tiles, and cement-based stone wall tiles, are commonly used for exterior wall decoration. They are often used on the interior and exterior walls of high-end buildings for reinforcement and aesthetics. However, these building decoration materials often require gluing real pebbles, cultural stones, and other materials onto the wall piece by piece, which is inefficient and prone to falling off, significantly limiting their application. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides a polypropylene imitation stone composite wall panel and a preparation method thereof.

[0004] In a first aspect, the present invention provides a polypropylene imitation stone composite wall panel. The raw materials for preparing the polypropylene imitation stone composite wall panel include the following components in parts by weight:

[0005] 80 parts of polypropylene, 16 parts of flame retardant, 0.5 parts of anti-ultraviolet and anti-oxidation composite additives, 1.5 parts of phase solution, 1.5 parts of dispersant and 0.5 parts of color masterbatch.

[0006] Furthermore, the flame retardant includes decabromodiphenylethane and antimony trioxide.

[0007] Furthermore, the anti-ultraviolet additive includes UV325 masterbatch.

[0008] Furthermore, the antioxidant aid includes antioxidant 1010 and antioxidant 168 masterbatch.

[0009] Furthermore, the phase solution includes a maleic anhydride grafted compatibilizer.

[0010] Furthermore, the dispersant includes EBS.

[0011] Furthermore, the color masterbatch includes masterbatch of colors such as gray, light yellow, light pink, and light green.

[0013] In a second aspect, the present invention provides a method for preparing the polypropylene imitation stone composite wall panel according to any one of the first aspects, the preparation method comprising the following steps:

[0014] Polypropylene monomer imitation stone tiles of various colors with a length of 150 mm, a width of 300 mm, and a thickness of 2 mm were respectively produced by injection molding;

[0015] The polypropylene monomer imitation stone tiles of various colors are again combined into multi-color polypropylene composite wall tiles by injection molding to obtain the polypropylene imitation stone composite wall panel.

[0016] Furthermore, when the polypropylene single tiles of various colors are prepared by injection molding, the injection molding machine needs to be equipped with a corresponding single tile special mold.

[0017] Furthermore, when preparing the polypropylene multi-color composite wall tiles by combining the individual tiles of various colors by injection molding again, the injection molding machine needs to be equipped with a dedicated composite mold that matches the above.

[0018] Furthermore, the above preparation method uses polypropylene multi-color mushroom stone wall panels as an example to illustrate the production method of multi-color polypropylene imitation stone composite wall panels. The material ratio and production method of other imitation stone polypropylene wall panels such as imitation granite and imitation pebbles are the same.

[0019] The above technical solution provided by the embodiment of the present invention has at least the following advantages compared with the prior art:

[0020] An embodiment of the present invention provides a polypropylene imitation stone multi-color composite wall panel, which uses a specific proportion of polypropylene as the main raw material to produce a polypropylene imitation stone composite wall panel that has the characteristics of being light in weight and easy and quick to install. It can effectively solve the problems of low installation efficiency and easy falling off of existing building decoration materials such as natural stones such as pebbles and mushroom stones.
