Abstract

The invention discloses a preparation process of high-strength base paper. The high-strength base paper is prepared from paper pulp, titanium dioxide, calcium carbonate, sodium hydroxide, wood fibers, starch, alum, an antibacterial agent, a cross-linking agent, paraffin and a drying agent according to a certain proportion. The process comprises the steps of pretreatment, pulp preparation, pulp netting, wet paper forming, drying and paper post-treatment. According to the preparation process of the high-strength base paper, the raw materials are reasonably selected and scientifically proportioned, and the corresponding processing technology is carried out according to the raw material components and proportions, so that the prepared base paper is relatively good in friction resistance. The alum is added to serve as a bridging agent, so that pulp fibers and glue are better connected together, and the friction resistance is improved; and by adding calcium carbonate and wood fibers, the overall structural strength is improved.

Description

technical field [0001] The invention relates to a paper preparation process, in particular to a high-strength raw paper preparation process. Background technique [0002] The paper-based friction plate is used as a medium for transmitting engine power to the gearbox, and its role is very important. The preparation of paper-based friction discs usually requires first to make the skeleton and the corresponding patch paper, and then attach the patch paper to the skeleton by a placement machine. [0003] The friction resistance of the existing sticker paper is average, which leads to a high degree of wear in the actual application process, and finally causes the life of the paper-based friction sheet to be limited, and its use cost is high. Moreover, the friction resistance of the sticker paper is average, and it is easy to cause failure due to wear and tear during use, which affects the safety of the equipment and seriously endangers the safety of personnel. [0004] Therefor...
