对进口乳胶纸的面涂胶乳进行红外光谱分析,结果表明所用的面涂胶乳为苯丙类乳液。采用进口浸渍纸为基纸,用多种苯丙乳液进行面涂试验研究。采用自制的软单体含量较高并能自交联的苯丙乳液涂布得到的乳胶纸,涂布量较小,抗溶剂性优良,面涂层不发黏,后续涂布酚醛树脂的纸张柔韧性最好,能满足后续植砂加工要求。 Infrared spectrum analysis of the surface-coated latex of imported latex paper showed that the surface-coated latex used was styrene-acrylic emulsion. Imported impregnated paper as base paper, with a variety of styrene-acrylic emulsion surface coating test study. The use of self-made high content of soft monomer and self-crosslinking styrene-acrylic emulsion coated latex paper obtained with a smaller amount of coating, excellent solvent resistance, the top coating is not sticky, subsequent coated phenolic resin paper The best flexibility to meet the follow-up planting sand processing requirements.
