明显降低 ；
（2）硫化胶的扯断伸长率升高，硬度和定伸应力
下降，拉断强度在使用 6 份时达到最大值 ；
（3）缓冲胶和布条之间的剥离强度与硫化胶的拉
伸强度呈现一定的相关性，在 6 份时达到最大值，且
在高附胶量和高含水量时剥离强度出现下降。

Effect of rosin on the mechanical properties of NR and the adhesion of
water-based adhesive

Abstract: This article investigates the effect of rosin on the vulcanization characteristics and mechanical
properties of NR, and also investigates the effect of rosin as a viscosity increasing resin added to a water-
based adhesive system on the adhesive properties of the adhesive. The results showed that as the amount of
rosin increased, the elongation of NR vulcanized rubber increased, the tensile stress and hardness decreased,
and the tensile strength reached its maximum at 6 parts; In terms of adhesive performance, the effect of rosin
on peel strength is consistent with its effect on the tensile strength of vulcanized rubber, reaching its maximum
at 6 parts.
Key words: V-band; wrapping adhesive; water based adhesive; thickening resin; peel strength
