Abstract

The invention discloses a preparation method of an anti-friction paper pulp molded product. The preparation method comprises the following preparation steps: S1, slurry preparation process, S2, molding process, S3, drying process, S4, moisture regaining process, S5, hot pressing process and S6, inspection process. According to the present invention, the length and the width of the fiber are small due to the secondary decomposition of the fiber, and the material contains the small particles, such that the synthesis degree of the fiber after the paper pulp molding cannot be 100%, such that the surface of the product is easily damaged, and the performance defect exists. According to the invention, fiber modification and filling of gaps among fibers are realized by using an additive and a combined formula, fine fibers and particles are effectively combined together, and a protective film is generated in a hot pressing process, so that the surface density of a paper pulp molded product is improved, and a friction-resistant protective layer is formed on the surface of the paper pulp molded product.

Description

Technical field [0001] The present invention is a pitch molding product field, which can increase the problems of low wear resistance and dandruff loss of products in the art. Improve the adverse phenomenon caused by friction during the logistics process. Background technique [0002] Because the recycling yellow pulp material is the recycling material, the fiber is small and width after two decomposition, and the length and width of the fiber are small, and the material also contains less particulate matter. These reasons cause the synthesis of the fiber after the mold is molded and mold cannot be intertwined with each other. As a result, the product's surface is easily damaged due to the bumps and frictions of the product due to the bumps and frictions of the product, thus falling off from the product surface of small fibers and particles, resulting in the appearance and performance defects that do not meet the standards. At present, the industry uses vibration testing ISTA3A t...
