Problems solved by technology

However, in the stretching process, inorganic metal fillers will also form fine pores on the surface of the pearlescent paper, which will affect the smoothness of the surface of the pearlescent paper
Moreover, in the subsequent processing technology, the solvent may infiltrate through the pores on the surface of the pearlescent paper, causing the deformation of the pearlescent paper and changing the size specifications, which will affect the subsequent application of the pearlescent paper
[0004] In addition, after a long time of use, the calcium carbonate on the surface of the pearlescent paper may fall off, causing powder removal on the surface of the pearlescent paper, causing inconvenience to the subsequent printing process, and making the surface of the pearlescent paper rough and affecting the quality
Therefore, existing pearlescent paper still needs to be improved

Abstract

A pearl paper and a method for manufacturing the same are provided. The pearl paper includes a first surface layer, a second surface layer, and a lightweight layer. The lightweight layer is disposed between the first surface layer and the second surface layer. The first surface layer is a polypropylene layer. The second surface layer is a polypropylene layer. The lightweight layer has a continuousphase part and a dispersed phase part. A material of the continuous phase part contains polypropylene and a material of the polymer dispersed phase part contains polyester. According to the invention, a film can be formed under the condition that calcium carbonate or calcium silicate (inorganic metal filler) is not added, and the light-weight pearl paper is manufactured.

Description

technical field [0001] The invention relates to a pearlescent paper and a manufacturing method thereof, in particular to a lightweight pearlescent paper without foaming agent and inorganic metal filler and a manufacturing method thereof. Background technique [0002] Pearl paper is a kind of synthetic paper, which is made of petrochemical synthetic resin. Compared with ordinary paper made of wood pulp, pearlescent paper has better water resistance, tear resistance and surface smoothness. However, the existing pearlescent paper uses polypropylene as the main material, and the density of the prepared pearlescent paper is usually high, so it cannot have the advantage of light weight. [0003] In order to reduce the density of pearlescent paper, an appropriate amount of inorganic metal fillers, such as calcium carbonate or calcium silicate, can be added to the polypropylene raw material for producing pearlescent paper. In this way, when the polypropylene raw material is in the...
