Abstract
本发明涉及一种硅烷改性生物基聚氨酯防水密封胶及其制备方法,所述硅烷改性生物基聚氨酯防水密封胶由25~40重量份硅烷改性生物基聚氨酯树脂、50~60重量份无机填料、5~15重量份环氧化植物油、1~5重量份硅烷偶联剂和0.1~0.5重量份催化剂混合而成。硅烷改性生物基聚氨酯树脂由生物基二元醇、二异氰酸酯、氨基硅烷合成。采用含生物基C36二聚体单元的大分子二元醇或共聚聚酯多元醇,赋予憎水、耐酸碱和抗紫外老化的能力。经1%硫酸、1%氢氧化钠、5%氯化钠水溶液浸泡60天,以及水‑紫外线处理2000小时后,拉伸强度保持率高于95%,断裂伸长率保持率高于90%。该密封胶能应用于建筑、家装等领域的防水密封。
Description
技术领域
本发明涉及一种硅烷改性生物基聚氨酯防水密封胶及其制备方法,属于密封胶技术领域。
背景技术
建筑和家居装修领域采用的密封胶通常是硅酮胶和聚氨酯密封胶。在长期使用过程中,某些特定位置的胶条受到长期的紫外线、高温、高湿等复杂环境的影响,硅酮胶的硅油成分会缓慢渗出,污染基材、影响美观,传统的聚氨酯密封胶由聚醚多元醇和异氰酸酯合成,聚醚多元醇软段和氨酯键容易在紫外线、酸、碱、盐的影响下发生老化。此外,聚氨酯密封胶往往含有邻苯二甲酸酯类增塑剂,欧美等发达国家地区已经将邻苯二甲酸酯类物质列为禁用或限制使用化学物质,而且邻苯二甲酸酯类物质分子量小、极性低,随时间延长也会迁移至表面,一方面导致密封胶老化、弹性变差,另一方面危害人类的身体健康。
密封胶老化的重要介质是水,蒸气形态的水分子渗透到密封胶内部,或溶解酸、碱、盐成分的水缓慢侵蚀到内部,在紫外线或高温的刺激下,将加速老化。专利CN201010593673、CN201610946574、CN201810264240和CN201911309263选择聚二甲基硅氧烷软段与常规聚醚多元醇复配合成聚氨酯预聚物,旨在利用聚二甲基硅氧烷的低表面能特性来提高密封胶疏水的能力,从而提升其防水能力。专利CN200910146833选用石油基烯烃类物质,即双环戊二烯石油树脂和由端羟基聚丁二烯合成的丁羟聚氨酯,同样是利用低表面能特性来赋予防水性能。
