Partial embossed wallpaper

technical field

The utility model relates to the technical field of embossed embossed wallpaper, in particular to a partially embossed wallpaper.

Background technique

Wallpaper, also known as wallpaper, is a widely used interior decoration material.

The local embossed wallpaper prepared in Example 6 of the utility model comprises a cotton and linen fabric substrate layer, a hydrophobic layer with a thickness of 0.015mm arranged on the surface of the cotton and linen fabric substrate layer; A base color layer with a thickness of 2 mm; a foam layer with a thickness of 2 mm arranged on the surface of the base color layer, and the surface of the foam layer is provided with pattern-shaped overlay embossing.

According to the method described in the above-mentioned technical scheme, the embossing accuracy of the local embossed wallpaper provided by Embodiment 6 of the utility model is tested; the test result is that the embossing accuracy of the partially embossed wallpaper provided by Embodiment 6 of the utility model is The degree is 0.2mm.

As can be seen from the above embodiments, the utility model provides a partially embossed wallpaper, comprising: a substrate layer; a hydrophobic layer arranged on the surface of the substrate layer; a foam layer arranged on a part of the surface of the hydrophobic layer , the surface of the foam layer is embossed in a pattern shape. The partial relief embossed wallpaper provided by the utility model contains a hydrophobic layer, and the setting of the hydrophobic layer can reduce the expansion and contraction performance of the base material layer, so that the embossing in the foam layer has better accuracy.
