Abstract
The invention provides a softening agent for papermaking. The softening agent for papermaking is prepared from imidazolium quaternary, nonionic surface active agents, phosphate ester and polyhydroxy derivatives, wherein the mass ratio of the imidazolium quaternary to the nonionic surface active agents to the phosphate ester to the polyhydroxy derivative is (1-20):(20-90):(5-15):(1-20). Through the adoption of the softening agent disclosed by the invention, not only the softness of paper can be improved, but also the hardness and the hygroscopicity of the paper are not influenced, and at the same time, the softening agent has the functions of withstanding bacteria and corrosion inhibition. The softening agent can be widely used for papermaking industry.
Description
technical field [0001] The invention relates to the technical field of papermaking, specifically an additive used in the papermaking process to improve the softness of paper without affecting the strength of paper. Background technique [0002] Paper products are widely used in various fields of life. With the development of science and technology and the improvement of life, more and more paper is used in daily life, and the quality requirements of paper are also getting higher and higher. Paper hardness, softness, water absorption, lint and powder resistance and other properties determine the quality of paper. These indicators have become the key issues for the paper industry to improve the quality of paper products. The softness of paper is achieved by adding paper softener. Paper softener is an additive that can be adsorbed on paper fibers to increase the softness of paper and make paper feel comfortable and soft. [0003] The use of paper softener can form a...
