降低双组分聚氨酯铺装材料异辛酸铅用量的研究

Reduction of Catalyst Lead Octoate in the Two component Polyurethane Paving Materials

研究了催化剂对双组分聚氨酯铺装材料固化情况及对产品物理性能的影响。为了降低催化剂异辛酸铅的用量 ,对复合催化剂的配比和用量进行了选择性实验。实验结果表明 ,异辛酸锌与异辛酸铅复合催化剂适合本体系 ,其质量比以

The effects of catalysts on the solidification and the mechanical properties of two component polyurethane paving materials were studied.The results showed that,to reduce the use level of lead octoate,complex catalysts of lead octoate and zinc octoate are suitable for this system.It is appropriate that the mass ratio of zinc octoate and lead octoate is 2∶1.And the amount of the complex catalysts was also selected.
