Description

Mold and method for manufacturing highly simulated stone and wood grain decorative panels

The present invention relates to a mold for manufacturing decorative panels and a method thereof, in particular to a mold and a method for manufacturing decorative panels with high simulation stone or wood textures.

It is reported that due to the complicated mining and processing of stone and other building materials, if natural stone is used for indoor or outdoor decoration design, its weight cannot be underestimated, and the installation process is time-consuming and labor-intensive, making it difficult to popularize it. Therefore, some industry players have launched lightweight imitation stone products. Quality decorative boards are used as building materials to be attached or fixed to the surface of buildings such as walls to reduce costs and installation time. The decorative boards are mainly made of polyurethane polyether polyol as raw materials, with additions such as catalysts, foaming agents and interfaces. Various additives such as active agent... are poured into the mold, and then the raw material is foamed and molded through the mold and demoulded to form a decorative plate. The surface of the mold is textured to match the decorative plate. The surface forms imitation stone texture.

However, when manufacturing the decorative panel, a release agent (also called a release agent) must be sprayed on the surface of the mold first to prevent the decorative panel from being unable to be demolded due to sticking to the mold during the foaming process. Cause damage to moldings or decorative panels. Moreover, the degree of simulation of the decorative plate is limited because the texture on the surface of the mold is not delicate enough, so that the imitation stone texture formed by the decorative plate is not similar to the real stone texture. However, if the texture on the surface of the mold is too delicate, even if it has been made in advance. Even if the release agent is sprayed on the surface of the mold, it will be difficult to demould the decorative panel from the mold, and forced demoulding may damage the mold or the formed decorative panel.

Moreover, the decorative board made of this polyether polyol is soft and easily damaged by external forces. Deformation occurs. For example, during construction, fixing elements (nails or screws, etc.) are applied to the decorative panel. Often, due to the deformation of the decorative panel, the fixing elements and the decorative panel do not mesh well, causing the decoration to be damaged. The board is prone to problems such as looseness and instability.

Therefore, how to provide a mold or method that can produce stone or wood decorative panels with high degree of simulation, facilitate the demoulding of decorative panels, and solve the above conventional problems and deficiencies, is the inventor of the present invention and is engaged in this industry.
