用浸涂法制备了G/MoS2/Ekonol/PES/PPS多元复合涂层,以涂层结合强度为评价标准,采用混料回归实验优化设计了G/MoS2/Ekonol/PES/PPS复合涂层的涂料配方,用拉开法测定复合涂层的结合强度,并对结合表面进行了观察和分析,研究了涂料组成、涂层制备工艺参数和涂层厚度对涂层结合强度的影响。结果表明,用浸涂法能制得力学性能优良的G/MoS2/Ekonol/PES/PPS复合涂层;采用典型配方Ekonol:PES:PPS:G/MoS2:助剂=25:20:45:8:2(质量比)能够得到较大的结合强度。
The composite coating of G / MoS2 / Ekonol / PES / PPS was prepared by dip coating method. The coating adhesion strength was used as the evaluation standard. The mixed G / MoS2 / Ekonol / PES / PPS composite coating Coating composition, the bonding strength of the composite coating was measured by open method, and the bonding surface was observed and analyzed. The effects of coating composition, coating preparation parameters and coating thickness on the bonding strength were studied. The results showed that G / MoS2 / Ekonol / PES / PPS composite coating with good mechanical properties could be prepared by dip coating method. The typical formulation Ekonol: PES: PPS: G / MoS2: additive = 25:20:45:8 : 2 (mass ratio) can get greater bonding strength.
