摘　　要：以改性松香树脂、350-1醇酸树脂和VA900型EVA树脂为成膜物质,并填加颜料、助剂和玻璃微珠制备了热熔型路标涂料,研究了影响改性松香树脂酸值和涂料软化点的条件,结果表明:改性松香树脂的酸值随反应时间的延长而下降,反应时间达到6h,反应温度为270℃时,酯化反应较完全,树脂的颜色较浅;改性松香树脂、350-1醇酸树脂和VA900型EVA树脂的质量比达到4:1:0.5时,涂料具有适当的干燥时间及较高的软化点。制备出的热熔型路标涂料具有干燥时间短、反光性能好、耐摩擦等性能,符合相关标准。The hot-melt road marking paint has been synthesized using modified rosin,alkyd resin and VA900-EVA resin as film forming material,while filling in pigment padding,assisted material and glass beads.The effect of sterification reaction time on acid value at different temperature in synthesizing modified rosin resin,and the proportion of thermoplastic resin are discussed in this article.This hot-melt road making paint has main characteristics such as durability,quickly drying and reflectivity while it conforms to the standard.The findings indicated that acid value of modified rosin drops along with the extension of reaction time.The esterification reaction has completed when reaction time achieves 6 hrs and temperature reaches at 270 ℃,so that modified rosin has shallow color.This coating has the suitable drying time and the high softening point when the quality proportion of modified rosin resin,350-1 alkyd resin,VA900-EVA resin is 4:1:0.5.
