Abstract

The invention discloses a novel environment-friendly cardboard material and a preparation method thereof. The preparation method comprises the following steps of: cleaning up, drying, smashing and grinding corncobs and bagasse to obtain mixed powder; well mixing regenerated paper pulp and plant fiber paper pulp in a beating machine, then adding the mixed powder, pretreated fly ash, starch modified white mud fibers and a composite antibacterial agent, and stirring and mixing well to obtain a pulp mixture; adding sodium hexametaphosphate and sodium dodecyl benzene sulfonate into the slurry mixture, and stirring and mixing to obtain slurry; and inputting the slurry into a paperboard forming machine for processing, and then drying to obtain the novel environment-friendly cardboard material. The plant fibers and the inorganic fibers in the prepared novel environment-friendly cardboard material are uniformly dispersed and smooth in surface, the binding force of the inorganic filler and the fibers is high, paper is high in strength and not prone to damage, the preparation raw materials are low in price and easy to obtain, economic benefits are high, and the novel environment-friendly cardboard material is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of wrapping paper processing, in particular to a novel environment-friendly paper shell material and a preparation method thereof. Background technique [0002] With the change of market demand, the development of the packaging industry is advancing by leaps and bounds. Ordinary wrapping paper is often used for a short period of time, and has the characteristics of low cost, light weight, easy processing, high strength, and convenient storage. In addition to the pulp, a certain amount of filler is added to the paper shell material. The filler can give the paper excellent whiteness, smoothness and opacity, and can also fill the gaps inside the paper to increase the density and uniformity of the paper. . On the other hand, most of the fillers are inorganic materials, which can reduce the addition of pulp, save wood resources, and reduce production costs. However, the addition of fillers will also have a cert...
