Abstract
Using butyl acrylate and styrene as monomers and potassium persulfate as the initiator, collagen extracted from discarded leather scraps was modified through emulsion polymerization to prepare a new collagen-modified paper surface sizing agent. . Using the product grafting rate and precipitation rate as inspection indicators, the preparation conditions of the modified collagen surface sizing agent were optimized through single-factor experiments; Fourier transform infrared spectrometer (FT-IR), laser particle size analyzer, and transmission electron microscope (TEM) were used ) to characterize the product and study its sizing properties. The results showed that a grafting reaction occurred between collagen and non-ionic monomers, and the grafting rate was about 65%. The product has a spherical structure, and its particles are regular in shape and uniform in size, with an average particle size of 0.117 ¦Ìm. Using it as a sizing agent can increase the ring crush strength and tensile strength of paper by 1.5 times and 1.8 times respectively, and reduce the water absorption value in 60s by 2.8 times, achieving strong water resistance. This article uses collagen extracted from waste leather scraps as raw material to prepare papermaking sizing agent. It not only promotes the resource utilization of leather solid waste, but also makes it possible to provide a new type of papermaking sizing agent for the papermaking industry.
