Abstract

The invention provides embossed paper and a preparation method and application thereof. The embossed paper comprises a resin embossed layer and a paper layer which are sequentially arranged in a stacked mode. The preparation method comprises the following steps: (1) mixing raw materials of the resin embossed layer, and then conducting melting to obtain molten resin; and (2) coating one side of a paper layer with the molten resin obtained in the step (1), and carrying out cold pressing through an embossing cylinder to obtain a resin embossed layer, thereby obtaining the embossed paper. The embossed paper provided by the invention can solve the problem that the appearance and the practicability are influenced by bubbling caused by long-term use of a sticker, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of composite paper, in particular relates to an embossed paper and its preparation method and application, in particular to an embossed paper with exhaust effect and its preparation method and application. Background technique [0002] Embossed paper is a kind of paper for cover decoration. It is called "embossed" because of the inconspicuous depressions on its surface. In the field of stickers, there is a problem that after long-term use, water and other substances in the sticker glue evaporate to produce bulges, which seriously affects the appearance and practical use. [0003] Disclosed in CN108221476A is a kind of color halo pearlescent laser transfer embossed paper and its manufacturing method, wherein the color halo pearlescent laser transfer embossed paper comprises: a base paper layer, a color halo pearlescent coating, coated on the top of the base paper layer; The paint layer is coated on the halo pearlescen...
