Problems solved by technology

[0002] Paper is a commonly used item in people's daily life. It can also be used for the transmission of information and the packaging of items. According to the hardness and smoothness of paper materials, paper materials with higher hardness and better smoothness can also be used in industrial applications. However, when the existing paper materials are used for industrial packaging, there are many problems as follows: firstly, the hardness and smoothness of the paper materials are not enough, which can easily cause damage to the product packaging, thereby affecting the quality of the product; secondly, if To increase the hardness and smoothness of paper, it is necessary to add chemical additives to the raw pulp, which not only increases the cost, but also causes pollution to the environment after being discarded.

Abstract

The invention discloses raw paper pulp. The raw paper pulp comprises leaf fiber pulp of dicotyledonous plants, wherein the leaf fiber pulp comprises celtis plant leaf fiber pulp, oak plant leaf fiberpulp, populas plant leaf fiber pulp and fagus plant leaf fiber pulp. The raw paper pulp has the beneficial effects that the raw paper pulp has good strength characteristics; the strength of a paper material can be improved by 30%-40% after the raw paper pulp is mixed with poor pulp for use; the raw paper pulp can also be independently used for preparation of a paper material; and the prepared paper material is high in hardness and attractive in appearance, meets the packaging requirements of industrial products is met, and can be recycled after being discarded.
