Abstract

The invention belongs to the technical field of pulping and papermaking processing, and particularly relates to a paper pulp release agent for household paper and a preparation method of the paper pulp release agent. The paper pulp release agent for the household paper is prepared from the following components in parts by mass: 40 to 50 parts of modified vegetable oil, 20 to 30 parts of beewax, 10 to 20 parts of ionic liquid, 10 to 20 parts of plant ash solution, 5 to 10 parts of glycerin monostearate, 3 to 6 parts of polyvinyl alcohol, 2 to 6 parts of polyethyleneimine, 3 to 5 parts of bactericide and 5 to 10 parts of sodium dodecyl sulfate. The release agent prepared by the method can be used for improving the bulk and softness of the household paper, enhancing the smooth and fine feeling of the paper, is relatively high in dry and wet strength and is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking processing, and in particular relates to a household paper pulp release agent and a preparation method thereof. Background technique [0002] Household paper includes roll paper, tissue paper, napkins, facial tissue, paper handkerchiefs, kitchen paper towels, etc., which are convenient for people to use at home and out. With the continuous improvement of people's material living standards, tissue paper has quickly become one of the most intimate consumer goods in people's lives. The production and market demand for tissue paper in my country has also grown rapidly, and people's quality requirements for tissue paper are also increasing. The higher it is, both the strength of the paper and the lightness and softness of the paper are required. The quality of household paper will directly affect the usage of consumers. More and more companies have begun to pay attention to the research...
