Description

Technical Field

[0001] The utility model relates to a high temperature resistant decorative paper with a multi-layer structure, belonging to the technical field of decorative paper. Background Art

[0002] Decorative paper is an indispensable raw material in many building materials products, such as low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards and floors. In the product structure, decorative paper mainly plays a decorative role in providing patterns and a covering role in preventing the bottom layer of glue from seeping through. This layer requires the paper to have good covering power, impregnation and printing properties. Decorative paper requires a smooth surface, good absorbency and adaptability, a uniform tone for base colors, and bright colors for colored ones.

[0003] However, the existing decorative paper may need to be placed outside during use. When the external sunlight is too strong, it will directly irradiate the decorative paper, which may cause it to be affected by high temperature. High temperature may cause the color of the decorative paper to darken or fade, affecting its aesthetics. Secondly, it may also cause bubbling and delamination, as well as deformation or shrinkage due to high temperature, affecting its flatness.

[0004] Therefore, a multi-layer high temperature resistant decorative paper is proposed. Utility Model Content
