Description

Technical Field

[0001] The utility model relates to the technical field of facing paper, in particular to a fireproof board facing paper. Background Art

[0002] Fireproof board facing paper is an important component of fireproof board veneer, and is mainly used to enhance the decorative effect of the material. Fireproof board facing paper has been specially treated, and it is not only rich in color and diverse in texture, but also has excellent wear resistance, corrosion resistance and aging resistance. During the production process, fireproof board facing paper is combined with a paper base (usually made of cellulose paper, wood fiber, etc.) and thermosetting resins, phenolic resins and other adhesives to form a strong and durable fireproof board veneer through a high temperature and high pressure process. This veneer not only has excellent fire resistance and can effectively prevent the occurrence and spread of fire, but also has excellent decorative effects and can meet various design requirements. In general, fireproof board facing paper is an indispensable part of fireproof board veneer. Its existence not only enhances the fire resistance of the material, but also provides rich visual effects for architecture and interior decoration.

[0003] Currently, most of the facing papers for fireproof boards on the market are single base layers with low toughness. They are prone to deformation and breakage during dragging or pulling. Breakage will make the facing panels unsightly on the fireproof boards and require tearing off and re-pasting, which wastes materials and takes time, reducing the efficiency of pasting facing papers for fireproof boards.
