Acrylic Soap Emulsion And Film-forming Characteristics

This work was financially supported by CNCCC institute. The targetis to meet the requirement of textile paste and interior or exterioremulsion. During textile process, yarn should endure repeating friction,tension, coil and impact. The paste is used to reduce the breakage rateand increase the yarn efficiency. During conventional method, PVA andstarch are used as the additives. However, the large amount of PVA hasmuch potential influence on the environment. Some of countries haveinhibited this product. In this work, we have done some research work toreplace PVA. The influences of emulsion polymerizing process, includingthe amount of sodium acrylate, monomers, initiators, buffering agents,polymerization temperature and agitating speed on the performance ofemulsion were discussed.The silicone modified acrylate and organic siloxane compositesurfactant-free emulsion were synthesized by the copolymerization oforganic silicone monomers containing double bond and acrylic monomers.The film forming process are analyzed by the testing technologies suchas Raman spectral, FTIR, and SEM. By using polyacrylate surfactantemulsion and silicone modified acrylated surfactant emulsion as binders,Textile sizes of good abrasion resistance, penetration resistance andexterior coatings with excellent chemical resistance are formulated.The experiment results indicated that the high solid polyacrylatesand organic siloxane modified surfactant-free emulsion can substitute PVAto increase the yarn efficiency with minimum impact on the environment.Moreover, the emulsions could provide excellent water resistance andabrasion resistance in application of textile sizes and exterior orinterior coatings of architecture.
