Embodiment 1

[0026] Embodiment 1: the manufacture of environment-friendly paper

[0027] With 70% weight of natural inorganic mineral powder (wherein heavy calcium accounts for 67% weight, titanium dioxide accounts for 3% weight); 2% weight auxiliary agent (wherein coupling agent accounts for 1% of weight, dispersant accounts for weight 0.5%, antioxidant accounts for 0.285% by weight, whitening agent accounts for 0.015% by weight, antistatic agent accounts for 0.2% by weight,), 18% polyethylene by weight (wherein high density polyethylene accounts for 12% by weight, 6% by weight linear low density polyethylene; 9% by weight polypropylene; 0.5% by weight butane and 0.5% by weight nucleating agent. The total weight of the above material ingredients is 100%. After powder modification, mixing, plasticization and kneading, it is made into a lump material, which is extruded by a paper film making machine to form a micro-foaming closed-cell structure of 100 microns to 200 microns and has a bidire...

Abstract

The invention discloses a stone papermaking method, which is characterized by comprising the following steps: adding 2 to 2.5 weight percent of auxiliary agent such as stearic acid and the like into 70 to 80 percent of natural inorganic ore powder such as heavy calcium, light calcium, talcpowder, titanium white powder and the like serving as main raw materials to modify the raw materials, adding 18 to 11.5 weight percent of polyethylene and 9 to 5 weight percent of polypropylene into the raw materials, and mixing, plasticizing and kneading the mixture to form a bulk material; and performing double-fold feed on the bulk material, pressing the bulk material into a paper film extruder, injecting 0.5 weight percent of butane and 0.5 weight percent of nucleating agent into the extruder, mixing and heating the mixture, extruding a paper film, then foaming, blowing, drawing, cooling and shaping the paper film to form a paper film base material, and forming a stone paper finished product through corona, coating, drying and finishing. The gram weight of stone paper is reduced by physical micro-foaming technology. The method has the advantages of simple manufacturing process, low cost, dry production, use of few water circulating cooling machines, no three-waste discharge and pollution avoidance.

Description

Technical field: [0001] The invention belongs to the field of light industry, relates to papermaking production technology, and is a manufacturing method of a novel environment-friendly inorganic powder paper. Background technique; [0002] Most of the existing traditional papermaking methods are produced by wet method, through a series of physical and chemical methods to process pulp and other complex processes, which consume a lot of resources such as water, electricity, coal, plants, manpower, etc., high cost, many processes, and pollution It is heavy, destroys the ecological environment, is difficult to control, and does not meet the current low-carbon and environmental protection requirements. Invention content: [0003] The purpose of the present invention is to provide a stone papermaking method, using inorganic mineral powder, adding a small amount of additives, modifying, adding an appropriate amount of auxiliary materials, and producing a new type of environmenta...
