Preparation method of novel environment-friendly paper

Abstract

A preparation method of a new type of environmentally friendly paper, including the following preparation methods: 1. Add dry inorganic powder and surface treatment agent together into a high-speed mixer, and stir to obtain a modified inorganic powder; 2. Mix the modified inorganic powder and The high-temperature-resistant polymer is mixed evenly and added to the internal mixer, melted and blended, and then granulated by single-screw extrusion to obtain mixed pellets; 3. Mix the mixed pellets, chain extender, heat stabilizer and foaming agent together , followed by twin-screw melt extrusion and blow molding to obtain a semi-finished product; 4. Put the semi-finished product at room temperature to obtain a finished product. The invention has low cost and environment-friendly materials. The prepared paper has high hardness and good toughness.

Description

technical field [0001] The invention belongs to the technical field of paper manufacturing, and in particular relates to a preparation method of a novel environmentally friendly paper. Background technique [0002] At present, many kinds of synthetic papers have been invented in the world. Among them, the single-layer and multi-layer synthetic papers with polypropylene as the main component and inorganic mineral powder as the filler are all manufactured with the traditional plastic film product formula. In the manufacturing process, single-layer or multi-layer co-extrusion is used, and the forming die is made into a sheet with a straight die structure. After longitudinal stretching, the two sides of the sheet surface are laminated with the sheet or coated with a film. , and then stretched transversely; the synthetic middle layer made has two-way stretching, while the surface layer has one-way stretching, becoming a multi-layer synthetic paper. If the sheet after longitudina...

Problems solved by technology

Among them, office paper for cultural writing includes offset paper, writing paper, electrostatic copy paper, computer printing paper, glossy paper, etc., which account for a considerable proportion. At present, one of the main problems of these office papers is that they are seriously insufficient in high temperature resistance (above 100°C). , especially in copying, computer printing, etc., often warp and wrinkle, and sometimes cause paper jams, etc., thereby wasting resources and affecting office efficiency
