Abstract

The invention discloses a thermoplasticity environmentally-friendly stone paper and a preparation method. The thermoplasticity environmentally-friendly stone paper comprises the following components in parts by weight: 80-90 parts of inorganic mineral powder, 3-5 parts of surface active ingredient, 2-3 parts of polymer monomer, 0.01-0.05 part of initiator and 5-15 parts of lubrication accessory ingredient, wherein the inorganic mineral powder is at least one of various inorganic mineral powders, such as wollastonite of which the grain diameter is 5-10 mu m, bentonite and the like; the surface active ingredient comprises at least one of anion surface active ingredient comprising inorganic acid ester; and the polymer monomer is one of methyl methacrylate, methyl acrylate, butyl acrylate and styrene. The thermoplasticity environmentally-friendly stone paper contains 90% of inorganic mineral powder, has favoarble thermoplasticity processing performance and can use the thermoplasticity processing equipment to carry out quick blow molding or calendaring and drawing shaping; and paper has obvious vertical and horizontal orientation, good deflection and strong rigidity, and appearance texture more approaches the traditional paper. The thermoplasticity environmentally-friendly stone paper is a novel environmentally-friendly paper.

Description

technical field [0001] The invention relates to an environmentally friendly paper with inorganic powder as the main component, commonly known as "stone paper" and a corresponding preparation method, more specifically, an environmentally friendly stone paper with thermoplastic processability and a preparation method. Background technique [0002] "Stone paper" is called "stone paper" because it contains inorganic powder components. It is a new type of paper derived from synthetic paper. It uses polymer resin as the main material and calcium carbonate as an auxiliary material. The synthetic paper is prepared by calendering processing equipment. Since the raw material of synthetic paper is mainly resin, the content of calcium carbonate powder is less than 40%, so not only the cost is high, but also depends on petroleum, and its application and development have been affected by petroleum. In recent years, this type of technology has made new breakthroughs in technological means,...
