Polypropylene decorative film for furniture surface facing

Abstract

The invention relates to the technical field of decorative facing materials, and discloses a polypropylene decorative film for furniture surface facing. The polypropylene decorative film consists of a polypropylene base film layer, a printing layer, a coating layer and a back gum layer, and the polypropylene base film layer is a sheet-shaped base film formed by mixing and melting polypropylene resin, light calcium carbonate, nano titanium dioxide, color master batch, polyurethane, polyethylene wax and the like and then extruding the mixture. According to the polypropylene decorative film for furniture surface facing, polymerization and cross-linking between low-molecular prepolymers or oligomers and active monomers in a photocureable coating are initiated through the energy of ultraviolet light to obtain a cured paint film, the paint film is high in adhesive force, the hardness can reach 1H, and due to the compact surface structure, the paint film is good in scratch resistance and pollution resistance; and a back gum has good compatibility with polypropylene, is non-toxic, does not absorb water, and has hot melting viscosity, and the formed back gum layer can promote the bonding strength when the back gum layer is attached to a base material plate, has good fluidity at high temperature, and has good water resistance, acid and alkali resistance and weather resistance.

Description

technical field [0001] The invention relates to the technical field of decorative facing materials, in particular to a polypropylene decorative film for furniture surface facing. Background technique [0002] Furniture board decoration materials are mainly impregnated film paper, PVC, and paint. Formaldehyde is contained in impregnated film paper and paint, which releases free formaldehyde during the manufacturing and use process, which is harmful to the ecological environment and human health. Pollution and hazards. With the emphasis on environmental protection and health, the pollution and hazards of free formaldehyde have attracted much attention. People talk about the discoloration of "aldehyde". There are many environmental problems such as oxins, and some countries have successively proposed plastic restrictions to limit the use of PVC. [0003] The product trend of furniture boards is also changing towards green, environmental protection and high performance. Polypro...

Problems solved by technology

[0002] Furniture board decoration materials are mainly impregnated film paper, PVC, and paint. Formaldehyde is contained in impregnated film paper and paint, which releases free formaldehyde during the manufacturing and use process, which is harmful to the ecological environment and human health. Pollution and hazards. With the emphasis on environmental protection and health, the pollution and hazards of free formaldehyde have attracted much attention. People talk about the discoloration of "aldehyde". There are many environmental problems such as oxins, and some countries have successively proposed plastic restrictions to limit the use of PVC.

[0003] The product trend of furniture boards is also changing towards green, environmental protection and high performance. Polypropylene (PP) is a polymer with high temperature resistance, good toughness and strong chemical corrosion resistance. The material itself does not contain chlorine, does not contain Harmful substances such as formaldehyde and heavy metals have excellent comprehensive properties and are the most promising thermoplastic polymer materials today. However, polypropylene itself is a non-polar polymer, and it is difficult to print ink on the surface. Technical bottleneck overcome by this utility
