Preparation and Sizing Performance of the Modified Collagen Surface Sizing Agent

Abstract:

Using collagen as the raw material, methyl acrylate and vinyl acetate as the soft and hard monomers, ammonium persulfate as the initiator, a surface sizing agent was prepared by the emulsion polymerization method to modified the collagen. The optimum prepared conditions were got by the single factor experiment, follow as m(soft monomer)/m(hard monomer) for 1:2 or 1:1, m(collagen)/m(monomer) for 1:2, the dosage of initiator for 0.8% of monomers amount, the reaction time for 2h. The FT-IR showed that the grafting reaction between vinyl monomers and collagen happened and the vinyl monomers reacted completely. The particle size distribution of the emulsion indicated that its size distribution was uniform and the average size was 0.117μm. The results of application experiments showed that the tensile strength and tearing strength of paper were stronger than that of base paper for 3 times and 1.9 times, after sizing by using the emulsion. The water-resistance of paper was also improved.
