| 目的 为了提高HGB与聚合物的相容性及共混物的静态接触角。方法 分别用三类含氟树脂(聚醚301M型氟碳树脂、聚酯JF2X型氟碳树脂、PF500型氟硅树脂)改性HGB。通过红外光谱、热重测试，评价各类含氟树脂表面接枝HGB的接枝效果，并与未改性HGB进行比较。通过测试三类改性HGB与未改性HGB的接触角，比较四种HGB的疏水性能，并通过扫描电子显微镜分析表观形貌，观察表面粗糙度对改性HGB接枝效果的影响。通过EDS对HGB表面的元素种类及含量进行分析。结果 红外光谱、扫描电子显微镜、EDS以及热重分析均证明，三类含氟树脂均成功接枝到HGB表面。由表面形貌可知，HGB表面接枝三类含氟树脂后，表面均变得粗糙，覆盖了一层包覆物。EDS测试发现，三类含氟树脂接枝的HGB均检出F元素，且氟硅树脂接枝的HGB的F元素最高。此外，经含氟树脂接枝的HGB静态接触角显著提高，聚酯型含氟树脂、聚醚型含氟树脂、氟硅树脂接枝的HGB的静态接触角分别为130.72°、146.80°、152.12°。结论 在常温条件下，该制备方法成功地将三种含氟树脂接枝到HGB表面，其中75 ℃下的接枝程度最高，最佳反应时间为10 h。 |

| Three types of fluorine-containing resins (polyether 301M fluorocarbon resin, polyester JF2X fluorocarbon resin, PF500 fluorosilicone resin) are used to modify HGB, thereby the compatibility of HGB with polymer and the static contact angle of the blend can be improved. The infrared spectroscopy test and thermogravimetric test are used to evaluate the effect of grafting HGB on the surface of various fluorine-containing resins, and compare with the unmodified HGB. The contact angle of three types of modified HGB and unmodified HGB are tested by static contact angle to compare the hydrophobic properties of the four types of HGB, and the appearance is analyzed by scanning electron microscope to observe the surface roughness so as to evaluate the modified HGB Grafting effect. The element types and contents of HGB surface are analyzed by EDS test. Infrared spectroscopy testing, scanning electron microscopy and EDS testing, and thermogravimetric analysis all prove that the three types of fluororesin are successfully grafted on the surface of HGB. Scanning electron microscopy proved that the three types of fluororesin are grafted on the surface of HGB with a rough surface, covered with a coating; EDS test proves that the F element detected on the surface of three types of fluororesin grafted HGB compared with the ungrafted HGB, and the F element on the surface of fluorosilicone resin grafted HGB is the highest. The static contact angle of HGB grafted with fluororesin is significantly improved. The static contact angle of HGB grafted on the surface of polyester fluororesin, polyether fluororesin, and fluorosilicone resin is 130.72°, 146.80°, and 152.12° respectively. Therefore, this preparation method successfully grafted three fluorine-containing resins onto the surface of HGB, among them, the highest degree of grafting is 75 ℃, and the best reaction time is 10 h under normal conditions. |
