摘要
Abstract
In this study,methyl methacrylate(MMA)was used as the hard monomer and butyl acrylate(BA)as the soft monomer.The pre-emulsified seed emulsion polymerization method was adopted.The crosslinking agent N-hydroxymethylacrylamide/methacrylic acid(NMA/MAA)was added to the core layer,and styrene(St)was added to the shell layer to prepare the cross-linked modified core-shell styrene-acrylic emulsion.The obtained emulsion was coated onto thin sheet paper to prepare barrier paper.FT-IR spectroscopy confirmed that MMA,BA,St,NMA/MAA all participated in copolymerization.NMA/MAA successfully grafted onto the main chain structure of the emulsion molecule.TEM indicated that the latex particles pres-ent a core-shell structure and had a uniform particle size distribution,with a particle size of approximately 111 nm.The barrier paper prepared with PMBS-NA3 emulsion(with St dosage of 20%and crosslinking agent dosage of 0.5%)had good water resistance,Cobb1 800 s water absorption value was 8.6 g/m2,which was approximately 48.5%lower than that of the barrier paper prepared with unmodified emulsion,and had excellent oil resistancd,kit grade reached 10 grade.关键词
