摘要： 对有机硅防雾耐磨涂料的固化反应过程用差热式扫描量热仪(DSC)进行分析, 再用FTIR 在位跟踪固化反应过程中特征官能团吸收峰的变化。结果表明, 有机硅胶体在140 ℃左右固化, 胶体中缔合羟基间脱水缩合速率很高, 羟基脱水程度与固化温度有关, 温度越高, 达平衡时羟基的浓度越低, 羟基浓度变化最大是在100 ～130 ℃, 由此确定最佳固化反应温度为120 ℃, 反应时间为1 h。把涂料分别涂覆在聚碳酸酯(PC)片材、聚酯(PET)薄膜、聚酯(PET)不干胶薄膜上, 所得涂层的防雾性、耐磨性、透明性、粘接性、抗破裂性优良, 表面均一平整, 铅笔硬度可达3H -4H , 与水的接触角为10°左右。

Abstract: Curing reaction process of anti-fogging and abrasion-resistant organosilicone coatings was studied by the method of differential scanning calorlmetry (DSC). Meanwhile absorption peak variations of the functional groups were characterized by in situ tracing of FTIR in the curing reaction process. The dehydration rate of the associated hydroxy groups in the organosilicone colloid is very fast at the initial time, while the dehydration degree is higher at higher curing temperatures, especially at 100～130 ℃, and the curing temperature of organosilicone coating was found at 140 ℃. At last, the optimum curing reaction conditions were determined:curing temperature of 120 ℃ and curing time of 1 h. Organosilicone coatings were coated on PC, PET film and sticky PET film. The properties of anti-fogging, abrasion-resistant, transparent, adhesive and anti-cracked were good, and the film is uniform. The pencil hardness of film is 3H-4H. The contact angle is 10° or so.
