A kind of modified asphalt adhesive was made using asphalt as base,butyl rubber as modifier,rosin resin as tackifier and asbestos powder as filler.
以石油沥青为基料,丁基橡胶为改性剂,松香树脂为增粘剂,石棉粉为填料,合成了一种汽车底盘 用改性沥青胶粘剂。
Hot -melt road marking coating is prepared by modified rosin resin,properties of coating is improved by hotplastic elastomer poly(ethylene-vinyl acetate).
采用改性松香树脂研制热熔型路标涂料。
The emulsifying conditions of rosin resin,with rosinate soap emulsifier, were studied.
以松香酸皂为乳化剂，对松香树脂的乳化条件进行了探讨，考察了松香树脂乳液的稳定性，并将稳定的松香树脂乳液以不同比例与天然胶乳混合，研究其复合稳定性，结果表明：混合时加入适量的ＴＸ－１０，可在较宽的配比范围内得到稳定的复合乳液，为水乳型橡胶压敏胶的生产提供了基本条件。
