Abstract

The invention discloses a high-quality environment-friendly recycled paper processing method, and belongs to the technical field of environment-friendly recycled products, and solves a problem in theprior art that environment-friendly recycled paper through the waste paper recycling production is lower in quality. The method comprises the following steps: (1), smashing sorted and cleaned waste paper, mixing and grinding the smashed paper and water to form paper pulp, and performing filtering and stirring to make recycled pulp; (2), making semi-finished base paper; (3), making semi-finished surface paper; (4), coating the upper surface of the semi-finished base paper with an adhesive, pasting the semi-finished surface paper on the semi-finished base paper, and compressing the paper througha roller press to make semi-finished raw paper; (5), coating the surface of the semi-finished raw paper prepared at the step (4) with surface coating liquid, and performing the drying, surface pressing and polishing, finishing and winding to obtain finished recycled paper; (6), filling a surface gap to make the surface even; (7), preparing composite gloss oil and coating the paper with the glossoil; (8), performing hot-stamping operations, and placing the paper quietly. The environment-friendly recycled paper prepared through the method is clean and flat, is higher in quality, and can be used in various fields.

Description

technical field [0001] The invention belongs to the technical field of recycled environmental protection products, and in particular relates to a processing method for high-quality recycled environmental protection paper. Background technique [0002] Recycled paper is made of waste paper, which is crushed, decolorized and pulped through various processes. 80% of its raw materials come from recycled waste paper, so it is known as low energy consumption and light pollution. Eco-friendly paper. There are many kinds of urban waste paper, and different types of waste paper are used as raw materials to make different recycled copy paper, recycled packaging paper, etc. Generally, it can be divided into two categories: one is low-grade paper such as liner paper and toilet paper; the other is paper for books, newspapers and magazines, copy paper, printing paper, postcards and exercise books. [0003] The paper produced through more than a dozen processes such as sorting, purificat...
