Abstract

The invention provides a graphene sizing agent composition and a preparation method thereof. The sizing agent comprises the following components: graphene or graphene derivatives, anionic surfactant, dispersant, paraffin, modified starch, shell polysaccharides, deionized water. The preparation method is as follows: dissolving the modified starch in deionized water to obtain a modified starch solution; adding a cationic surfactant, paraffin and chitosan to the modified starch solution, and dispersing to obtain a composition A; The composition A is mixed with graphene or graphene derivatives and a dispersant, and after dispersion, emulsified, and the pH is controlled to be 4-5 to obtain the sizing agent composition. The invention has the following beneficial effects: it can significantly improve the antibacterial, anti-mite and anti-mildew properties of paper; it can significantly improve the strength of paper; the bursting strength of paper is increased to 4.5kg; it can be widely applied to toilet paper, antibacterial medical In the production and processing of cultural paper.

Description

technical field [0001] The invention relates to a graphene sizing agent composition and a preparation method thereof, belonging to the technical field of papermaking additives. Background technique [0002] Sizing agent, also known as pulp sizing, is a papermaking additive used to treat pulp, paper, and cardboard to achieve fluid penetration resistance, and can endow paper and cardboard with ink resistance, water resistance, emulsion resistance and Corrosion and other properties, thereby improving the smoothness, strength and service life of paper and board. [0003] After the existing sizing agent is used, the strength of the paper is poor; the antibacterial property is poor and it is easy to breed bacteria after being dripped with organic stains; the service life of the paper is small and it is easy to mold. Contents of the invention [0004] For the defects in the prior art, the object of the invention is to provide a kind of graphene sizing agent composition and prepa...
