Abstract

The invention discloses a recycled paper pulp prepared by utilizing waste paperboards, and relates to the technical fields of paperboard processing and production. The recycled paper pulp includes thefollowing raw materials in parts by mass: 300-500 parts of the waste paperboards, 100-150 parts of bagasse, 1-4 parts of a thermal initiator, 1-4 parts of a defoaming agent, 2-8 parts of an oxidant,10-20 parts of bentonite, 10-30 parts of fish bone meal, 2-8 parts of flour, 2-8 parts of citric acid, 2-8 parts of vinasse residues, 4-20 parts of solanine, 0.2-0.4 part of an auxiliary agent, 5-10 parts of a flame retardant, 5-8 parts of a waterproof agent, 50-80 parts of PVC particles, 5-10 parts of lime powder, and 5-10 parts of orange peel powder. According to the recycled paper pulp providedby the invention, the recycled paperboards are utilized to perform the reconstitution process of the paper pulp, the process steps are simple, the produced paper pulp has good quality, and the processed paperboard has good waterproof and fire-retardant capacity, thereby facilitating the improvement of the antibacterial effects and use effects of the paperboard.

Description

Technical field: [0001] The invention relates to the technical field of cardboard processing and manufacturing, in particular to recycled pulp prepared from secondary recovered waste cardboard. Background technique: [0002] With the rapid growth of online shopping and express delivery, the demand for carton packaging is increasing day by day. However, the widespread use of packaging cartons also brings unreasonable allocation of resources, resulting in a large number of cartons being discarded and wasted after being used once. , so as to cause adverse effects on the environment and resources; [0003] The cartons can be reused after recycling, and the more damaged cartons can be rebuilt. The present invention provides a process for preparing paper pulp from waste cardboards recycled twice. By improving the process of pulp, the quality of pulp is improved, and it plays a positive role in promoting the processing and production of cardboard in the later stage. Invention co...
