新型高黏着力化学浆料的合成及应用

Synthesis and Application of New Chemical Sizing Agent with High Adhesion

以乙酸乙烯酯、苯乙烯、丙烯酰胺、丙烯酸丁酯、丙烯酸为单体,以十二烷基苯磺酸钠等配制成的复合乳化剂为乳化剂,过硫酸铵为引发剂,采用自由基乳液聚合法,合成了高性能化学浆料,并进行了浆料性能测试及浆纱试验.结果表明:通过优化单体配比所合成的浆料具有高黏着力、低吸湿、低再黏等性能,与P24变性淀粉配合,作为主浆料取代PVA上浆,其浆纱质量好,织造效率高,布面质量好,得到用户的好评.

In order to synthesize new chemical sizing agent with high adhesion,low moisture absorption and low viscosity,synthesis of high performance chemical sizes was undertaken by free radical emulsion polymerization using vinyl acetate,styrene,acrylamide,butyl acrylate and acrylic acid as monomers,compound emulsifier as emulsifying agent which are the mixture of anionic emulsifiers（dodecyl benzene sulfonic acid sodium.etc） and nonionic emulsifiers and ammonium persulfate as initiator in this study.Properties of sizing agents were examined and sizing experiment was carried out.The results indicate that： synthesis of sizing agents by optimizing the monomer ratio has high adhesion,low moisture absorption,low viscosity etc.Synthesis of sizing agents with P24 modified starch,as the main sizing agents to replaced PVA sizing,which improves sizing quality,enhances weaving efficiency and cloth cover quality,is well received by customers.
