Preparation method of paper pulp with walnut shell as raw material

Abstract

The invention discloses a preparation method of paper pulp with walnut shell as a raw material. The raw materials of the paper pulp comprise the following components, in parts by weight: 400-450 parts of walnut shell, 1-4 parts of a heat initiator, 1-4 parts of a defoaming agent, 2-8 parts of an oxidant, 10-20 parts of bentonite, 10-30 parts of oyster shell powder, 2-8 parts of medical stone powder, 2-8 parts of limonene, 2-8 parts of distillers' grain residue, 4-20 parts of toosedarin-containing plant insecticide, and 0.2-0.4 part of an auxiliary agent. According to the invention, waste is utilized, and the paper pulp is energy-saving and environmentally friendly. The paper pulp has special insect-resistant and antibacterial functions, and has long service life and high cleanness. With the paper pulp, worm damage and bacterium growth can be effectively prevented, such that collection and preservation are facilitated. The paper pulp has high safety, and the method has an important significance. The method can be widely popularized for application.

Description

technical field [0001] The invention belongs to the field of pulping, and in particular relates to a pulp and a preparation method thereof. Background technique [0002] Traditional pulping refers to the production process of using chemical methods, mechanical methods or a combination of both to dissociate plant fiber raw materials into natural or bleached pulp. The commonly used process is to crush the plant fiber raw materials, cook, wash, screen, bleach, purify, and dry the pulp. A new biopulping method has been developed in modern times. First, special bacteria are used to specifically decompose the lignin structure, and then mechanical or chemical methods are used to dissociate the remaining cellulose, and then bleached. In this process, the organisms have already decomposed and opened most of the lignin, and the chemical method is only used as an auxiliary function. Compared with the traditional method, the chemical products used are less, so it can achieve less or no...

Problems solved by technology

[0003] Pulp prepared by various methods is used to prepare paper products in human life. However, since the pulp raw materials are prepared from natural organic materials, the prepared paper products are easy to be corroded, or easy to attract flies or easy to grow. mold, so it is necessary to develop a variety of pulps for users to choose and use according to their needs
