摘 要: 采用苯乙烯-丁二烯-苯乙烯(SBS)和苯乙烯-异戊二烯-苯乙烯(SIS)嵌段共聚物,并配合极性的环氧化SBS(ESBS)和环氧化SIS(ESIS)作为基体材料,制备了环氧化SDS(苯乙烯系热塑性弹性体)型热熔压敏胶。研究了ESBS和ESIS用量对压敏胶的初粘力、持粘力和在不同极性底材上剥离强度的影响。结果表明,随着ESBS和ESIS用量的增加,压敏胶的初粘力和持粘力下降,在聚乙烯(PE)上的剥离强度下降,但在聚氯乙烯(PVC)和不锈钢上的剥离强度先增加后下降。当ESBS和ESIS的质量份数均为20份时,压敏胶的初粘力和持粘力分别为23#和43.6 h,在PVC和不锈钢底材上的剥离强度分别达到0.82 N/mm和1.10 N/mm。 Epoxidized SDS based-hot melt pressure sensitive adhesives(HMPSA) were prepared with styrene-butadiene-styrene(SBS) block copolymer,styrene-isoprene-styrene(SIS) block copolymer,epoxidized SBS(ESBS) and epoxidized SIS(ESIS) as base materials.The effect of the amount of ESBS and ESIS on the tack property,holding power and peel strength on different polar substrates was studied.The results showed that with the increase of the amount of ESBS and ESIS,the tack property,holding power and the peel strength on PE ...
