Problems solved by technology

In recent years, research on improving and perfecting the application performance of styrene-acrylic emulsions has become increasingly active. Researchers have used polymer solutions or emulsions as emulsifying dispersants for styrene-acrylic emulsions to eliminate some of the shortcomings of traditional emulsifiers, but their emulsifying performance is poor. Disadvantages of high emulsion viscosity and poor stability

Abstract

The invention relates to a cultural paper reactive emulsifier surface sizing agent which has molecular structure as the following. The preparation method consists of the steps of: reacting polyethylene glycol, lauryl alcohol, and maleic anhydride so as to obtain maleic acid polyethylene glycol ester dodecy, then with ammonium persulfate and sodium bisulfite as the initiators, subjecting maleic acid polyethylene glycol ester dodecy, styrene, methyl methacrylate, acrylic acid-2- ethylhexyl acetate, hydroxyethyl acrylate, acrylamide and dimethyldiallylammoniumchloride to a core-shell copolymerization reaction so as to prepare the cultural paper reactive emulsifier surface sizing agent. The obtained cultural paper reactive emulsifier surface sizing agent can enhance the strength, water resistance and stiffness of cultural paper, and can substantially improve the wear resistance, printing ink affinity, permeability, stiffness and other application performances of paper. In printing, the cultural paper reactive emulsifier surface sizing agent of the invention can make the printing ink brighter and clearer, and simultaneously greatly mitigates the phenomena of cross color, strike-throughand linting and dusting etc. in color printing.

Description

technical field [0001] The invention relates to the field of preparation of surface sizing agents, in particular to a cultural paper reactive emulsifier surface sizing agent and a preparation method thereof. Background technique [0002] my country's forest resources are poor, and the raw materials for papermaking are mainly wheat straw and waste paper. The fibers of wheat straw and waste paper are short, the strength is poor, and there are many miscellaneous cells, which greatly affects the quality of paper. The surface strength, smoothness, printability and ink absorption performance of paper are getting higher and higher, and the paper used now is due to the addition of more fillers, which causes the surface strength and smoothness of the paper to decrease, so that the printing process occurs. Powder shedding phenomenon. The surface strength of the paper is directly related to the speed of the paper machine, the application performance of the paper, and the shelf life of t...
