Manufacture method of synthetic paper

Abstract

The invention discloses a manufacture method of synthetic paper, which is used for manufacturing the synthetic paper with resin as a base material and stone powder as filler. The process steps include stone power drying-stone power modifying-banburying pelleting of the stone powder and the resin-flow calendar extruding raw paper of the synthetic paper-raw paper heating drawing- corona processing-coating processing. Compared with the film blowing method, the manufacture method improves filling quantity of inorganic powder by more than 10% and especially increases the paper pattern processing process. Craquelure is formed on the surface of the synthetic paper after drawing, so that printing ink can be easily adsorbed, and the writing and printing performances of the synthetic paper are much closer to those of plant fiber paper.

Description

technical field [0001] The invention relates to a method for manufacturing synthetic paper, which belongs to the technical field of synthetic paper. Background technique [0002] Traditional paper is made of interwoven plant fibers, and the surface is covered with tiny pores, which have good permeability and adsorption to ink. In order to reduce the dependence on plant fibers and overcome the environmental pollution caused by paper production, modern times have developed the technology of making paper substitutes using polymer materials as substrates and filling them with inorganic substances. This kind of paper substitutes is called synthetic paper. Synthetic paper is highly praised by contemporary society because of its rich raw materials and little environmental pollution caused by the production process, also known as environmentally friendly synthetic paper. [0003] Currently commercially available synthetic paper is made of polymer materials filled with inorganic fi...

Problems solved by technology

Synthetic paper production technology including the prior patent application CN101701433 of the applicant is based on CaCO 3 、TiO 2 Such materials are filled with polyolefin, flow calendered to make base paper film, and then stretched, which greatly improves the performance of synthetic paper, but the similar plastic processing method used can only add about 40% to 50% of inorganic powder If the filler exceeds this ratio, it cannot be processed into paper
