摘要
目的:了解自然老化对内着色SY-1硅橡胶色彩稳定性的影响,以便为选用适宜的硅橡胶着色颜料提供理论依据。方法:SY-1硅橡胶按所加色料不同分为4组(对照组、水粉颜料土黄色、油画颜料土黄色、无机盐类颜料中铬黄),按国家标准对其进行自然老化同时避光保存并测定老化前后L*、a*、b*值,据此计算DE值。结果:经避光保存6个月,对照组△E为0.78±0.02;水粉土黄组DE为3.95±0.40;油画土黄组DE为2.0±0.12;中铬黄组DE为1.4±0.07。经自然老化6个月,对照组DE为1.32±0.01;水粉土黄组DE为6.69±0.12;油画土黄组DE1.79±0.42;中铬黄组DE为20.14±0.13。结论:SY-1硅橡胶在自然老化条件下,油画类颜料色彩稳定性优于水粉颜料和无机盐类颜料。
Objective: To explore into the effects of ozone aging factors on the color stability of the SY-1 siliconeelastomer so as to select the best pigments for clinical application. Methods: Consulting 1976 CIE LAB standards ofchromatic aberration, we analyzed the effects of ozone aging on the color stability of SY-1 silicone elastomers paintedwith three color series (control, gouache color, oil pigment and inorganic salts). Results : Under the timepass conditionfor six month ,the DE of control is 0.78±0.02, gouache color was 3.95±0.40 oil pigment was 2.0±0.12; inorganicsalts was 1.4±0.07 respectively; Under the nature condition for six month ,the DE of control was 1.32±0.01, gouachecolor was 6.69±0.12 oil pigment was 1.79±0.42; inorganic salts was 20.14±0.13 respectively. Conclusion: Underthe nature aging condition, the SY-1 silicone elastomers stained with oil pigment showed better color stability than thatwith gouache color and inorganic salts.
