The invention discloses a waste paper pulping auxiliary and a waste paper papermaking process. The component of the pulping auxiliary is high-molecular vegetable protein. The pulping auxiliary used inthe invention is a neutral product, does not corrode moulds, and can increase the fusion degree of talcum powder or calcium carbonate with paper fibers. According to the waste paper papermaking process provided by the invention, the paper usage quantity is reduced by 20%, the forming speed is high, the water content of products is reduced, the drying energy and the drying time are saved, the drying cost is saved by 30%, and the production efficiency is improved by about 30%. The product of the embodiment has low moisture absorption rate and high product strength. 本发明公开了种废纸制浆助剂及废纸造纸工艺，所述制浆助剂成分为高分子植物蛋白。本发明所用制浆助剂为中性产品，不腐蚀模具，能增加滑石粉活碳酸钙与纸纤维的融合度。本发明废纸造纸工艺，节约用纸量20%，成型速度快，降低产品含水量，节约干燥能源和干燥时间，节约干燥成本30%，提高生产效率约30%。本实施例产品吸潮率低，产品的强度高。
