Embodiment Construction

[0051] see figure 1 As shown in the process flow chart of the present invention, a method for preparing high-performance wear-resistant paper, the wear-resistant paper is made by mixing coniferous wood pulp, powdered corundum pulp and additives, then going online, pressing, and drying, wherein , including the following steps:

[0052] The first step of raw material configuration:

[0053]Powdered corundum (purity 99.5%, specific gravity 3.9-4.1g / cm 2 , the particle size is 45-106um, of which the proportion of 53-75um powder accounts for about 87% of the total weight, and the powder corundum is activated and modified by silane coupling agent), water and dispersant, including sodium hexametaphosphate and Add sodium polyacrylate (Rohm and Haas ACUMER9400) into the dispersion bucket and mix, sieve with 150 mesh, and set aside;

[0054] Measure the additive wet strength agent (Hanghua Harima ws-1) and sieve it through 300 mesh, and set aside;

[0055] The coniferous wood pulp a...

Abstract

The invention relates to a preparation method of high-performance wear-resistant paper, comprising the following steps in sequence: the materials are prepared: powdered corundum, water and a dispersing agent are added in a dispersing barrel for mixing and sieved for spare use; an auxiliary agent is sieved for later use after being metered; soft wood pulp and water are crushed by a hydrapulper and pass through a first pulse storing pool and a double-disc grinder to enter a second pulp storing pool for later use; three types of spared pulp are mixed in a batching pool and mixed pulp is prepared; the mixed pulp passes through a papermaking pulp pool, a high-position box, a slushing pump and a step diffuser; the mixed pulp passes through an inclined net, and the netting concentration is 0.03-0.08%; and then squeezing and drying are carried out. The preparation method has the advantages that the mixed uniformity is improved by adopting the preparation technique of respectively preparing the soft wood pulp, the powdered corundum pulp and the auxiliary agent and then mixing, especially the powdered corundum is pre-dispersed, the pheonomenon that the bad dispersion of the corundum cause defects on the appearance quality brought by the finished wear-resistant paper, and the definition and the transparency are improved. In addition, the retention of the corundum is improved, and the used amount of the corundum is reduced.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a preparation method of high-performance wear-resistant paper. Background technique [0002] Modern papermaking procedures can be divided into main steps such as pulping, modulation, papermaking, and processing. Among them, the preparation process is one of the key points of the papermaking process. The strength, color tone, printing quality of the finished paper, and the length of the paper shelf life are directly related to it; the main work of the papermaking process is to evenly interweave thin paper materials. and dehydration, then drying, calendering, rolling, cutting, sorting, and packaging, so the common process is as follows: [0003] a. Screening of paper materials: Dilute the prepared paper materials to a lower concentration, and use screening equipment to screen out impurities and undissociated fiber bundles again to maintain quality and protect equip...
