Problems solved by technology

However, the softener only has the effect of improving the softness of the paper, and cannot improve the properties of the paper such as mildew resistance and whiteness.
[0010] At present, there are few softeners with smooth, soft and mildew-proof properties on the market, and some paper softeners have an impact on the whiteness, shade and other properties of paper.

Abstract

The invention relates to the technical field of softening agents, in particular to a softening agent special for paper softening and mould proofing and a preparation method thereof. The softening agent is prepared from the following components in parts by weight: 5-10 parts of resin, 3-8 parts of cetyl dimethicone, 2-5 parts of nano zinc oxide, 2-5 parts of chitosan, 2-4 parts of hydroxyethyl cellulose, 3-5 parts of an aloe extract, 1-2 parts of a solvent, 1-2 parts of a pH regulator, 2-3 parts of liquid wax and 5-10 parts of water. The softening agent has the advantages of being good in handfeeling and water and mold proofing effect, high in stability and free of influences on paper whiteness.

Description

technical field [0001] The invention relates to the technical field of softeners, in particular to a special softener for paper softening and mildew resistance and a preparation method thereof. Background technique [0002] Softeners are compounds that contain long-chain hydrocarbon groups at one end of their molecular structure and polar or reactive groups that can bind to fibers at the other end. Softener molecules can form hydrophobic groups on the surface of fibers to adsorb outwards, thereby reducing the dynamic and static friction coefficients of fiber materials and obtaining a smooth and soft feel. Papers that require high softness include toilet paper, crepe paper, handkerchief paper, napkins, etc. Other paper types such as processed paper have higher and higher requirements for softness, so the application of softeners in papermaking has attracted more and more attention. . [0003] The function of softener can be roughly divided into two aspects: one is to improv...
