Tribological Property of Polycyclotriphosphazene-Sulfone Microsphere/Epoxy Resin Composite Coating

摘要

摘要: 以六氯环三磷腈为原料合成聚环三磷腈-砜(PCPS)微球, 用其对环氧树脂进行填充改性, 采用空气喷涂方法在钢板表面制备复合涂层, 通过XRD、SEM和滑动摩擦磨损试验机等研究了PCPS微球及其复合涂层的结构, 考察了微球含量对复合涂层摩擦学性能的影响。结果表明: PCPS微球为非晶结构, 平均粒径约为493 nm, 在涂层中分散均匀; 涂层的摩擦因数和磨损量均随微球含量的增多而先减小然后略微增大, 微球质量分数为3 %时涂层的摩擦因数最低且磨损量最小, 分别为0.37和1.8×10-6 mm3, 其磨损以粘着磨损机理为主。

Abstract: Polycyclotriphosphazene-sulfone (PCPS) microsphere synthesized with hexachlorocyclotriphosphazene as raw material was used to prepare epoxy resin composite coatings by air spraying on the surface of steel sheets. Structures of PCPS microsphere and composite coatings were analyzed by XRD and SEM, and the effects of microsphere content on the tribological properties of composite coatings were investigated on a friction and wear tester. Results show that PCPS microsphere with 493 nm average diameter had amorphous structure and could well disperse in coatings. The friction coefficient and wear loss of composite coatings first decreased and then increased with the increase of microsphere content, and the composite coating with 3 wt.% content of PCPS microsphere exhibited the lowest friction coefficient of 0.37 and the smallest wear loss of 1.8×10-6 mm3. Adhesive wear mechanism played a dominant role during wear process.
