joint sealant

In this paper,the performance of aging and fatiguing resistance of joint sealers is tested by taking a cycle-experiment of hot-pressed and hard-drawn to simulate the real application of joint sealers.

通过对比试验研究,得出以硅氧键为主链的有机硅填缝材料的抗疲劳老化性能优异,经热压冷拉后,粘结强度保持在95%以上,远高于国内目前普遍使用的聚氨酯、焦油型和芳油型填缝胶。
