Abstract

The invention discloses short glass fiber PP (polypropylene) stone paper, which comprises upper and lower surface layers and an intermediate layer, wherein the master batches of the upper and lower layers are composed of 40-60wt% of CaCO3, 37-55wt% of PP homopolymer and the balance of processing auxiliary agent; the master batch of the intermediate layer is composed of 25-30wt% of short glass fiber, 35-50% of PP (homopolymer), 20-30% of hollow glass microbeads and the balance of processing auxiliary agent; and the master batch of the intermediate layer accounts for 70-90% of the total master batch mass, and the master batch of each of the upper and lower surface layers accounts for 5-15% of the total master batch mass. The invention also discloses a preparation method of the short glass fiber PP stone paper. The preparation method comprises the steps of: preparing master batches of the upper and lower layers as well as the intermediate layer, carrying out extrusion forming on the master batches of each layer, and calendering to obtain the finished product. The stone paper is low in specific gravity, good in physical properties and superior in comprehensive performances, and can satisfy the use requirements of every field.

Description

technical field [0001] The invention relates to the technical field of synthetic paper, in particular to short glass fiber PP stone paper and a preparation method thereof. Background technique [0002] Stone paper is also called Shike paper, which is made of powdered stone as the main raw material, plus 15% polyethylene and 5% adhesive. In the whole production process, there is no need for water, strong acid, strong alkali, bleaching powder and many organic chlorides. Compared with the traditional papermaking process, several important pollution steps such as cooking, washing, and bleaching are eliminated, and the papermaking process is fundamentally eliminated. Pollution problems caused by the production of "three wastes". This kind of paper is waterproof, strong and not easy to burn. The most important thing is that it does not need to cut down trees to make paper and will not produce pollutants. It is very environmentally friendly and is valued by people. [0003] Howev...
