Abstract

The invention relates to a hydrophobic high-wear-resistance paper pulp material and a preparation method thereof. According to the method, a fluorocarbon compound is used as a hydrophobic agent and added into a paper pulp forming formula to achieve a high hydrophobic effect; by an atomic layer deposition technique, surface modification of a paper pulp material with an inorganic nano oxide is realized, surface roughness of the paper pulp material is improved, and surface wear resistance of the paper pulp material is realized. Compared with the prior art, the hydrophobic wear-resistant paper pulp material has advantages that abrasion performance of paper pulp is substantially enhanced, and an excellent water-resistant effect is achieved. In addition, the preparation method is simple, and performances of an obtained product are evidently superior to those of existing products on the market.

Description

technical field [0001] The invention relates to the field of preparation of cellulose materials, and relates to a method for preparing a hydrophobic and highly wear-resistant pulp material and its products, in particular to the modification of the cellulose material to prepare the hydrophobic and highly wear-resistant pulp material. Background technique [0002] Pulp is a fibrous substance made from plant fibers and processed by different processing methods. It can be divided into many subdivided varieties according to the source of raw materials, processing methods, and processing degrees, and can be widely used in papermaking, man-made fibers, plastics, etc. , chemical industry and other fields. [0003] With the continuous improvement of environmental protection awareness, pulp products are also popularized. But for some special occasions and applications, the performance of the pulp itself cannot meet the needs of the product. For example, the water resistance of paper...
