技術名稱: 矽複合水性PU製程技術開發

技術簡介

本技術克服Silicone在PU共聚合中相容性不佳的問題,成功的將Silicone導入PU中、合成矽複合水性PU,與國內外使用水性PU摻合矽油添加劑之混合技術不同。

Abstract

This synthesis technology overcomes the poor compatibility of silicone in silicone/PU copolymerization system, and silicone is incorporated successfully with PU to synthesize silicone-modified PU dispersions, which are different from silicone oil-blended PU dispersion

技術規格

反應時間≦8小時,反應溫度≦100℃;乳液固形份≧30%,黏度≦200 cps;固體中矽單體含量:0.5~20 wt%,乾膜延伸率≧300%

Technical Specification

reaction time≦8 h, temp.≦100℃; solid content≧30%, viscosity≦200 cps, silicone content: 0.5~20 wt%; film elongation≧300%

技術特色

利用化學共價鍵將Silicone與PU結合在一起,化學鍵不易斷裂、使Silicone可以於PU樹脂中長期發揮功用,不似外添加型矽油的不耐水洗性;藉由PU導入矽烷之控制技術,可達成表面張力(Surface Tension)的微調,產品更可應用於防水性能要求較高的地方。
