| 目的 为提高复合材料涂装前的喷漆表面平整度，保证漆膜表面状态。方法 分别采用表面修整剂、针孔填充剂和封孔剂等三种工艺材料，对玻璃纤维增强树脂基复合材料表面进行喷漆前的表面修整，并涂装配套的防护底漆。通过对修整材料的固化性能、与基材及漆层的表面结合力以及涂层系统相容性等性能进行测试，并与未使用工艺材料进行表面修整处理的复合材料喷漆后的表面状态进行对比，评价三种工艺材料的工艺性能、附着力及与涂层的相容性等。结果 在树脂基复合材料表面，涂装前配套使用针孔填充剂和封孔剂或针孔填充剂和表面修整剂进行表面修整，可有效降低复合材料表面针孔、凹坑等缺陷对涂装外观的影响，且漆层与基底的结合力大于15 MPa，与未使用工艺材料的涂层系统比较，性能未下降。结论 三种工艺材料与底面漆的相容性良好，对涂层力学性能及耐介质性能无不良影响，可配套用于复合材料涂装前的表面修整，提升涂装表面状态。 |

| The work aims to improve surface evenness of fiber reinforced composites before painting, and guarantees surface conditions of paint films. To-be-painted surfaces of the composites were finished with process materials. Three kinds of process materials including surfacer, pinhole filler and sealant were used for surface finishing of glass fiber-reinforced resin-based composites, and then for painting matched protective primer. Process properties, adhesion and compatibility with coating of the three process materials were evaluated by testing curing property of finished materials, adhesion to substrate and paintcoat, and coating system consistency, and comparing surface conditions of painted composites not finished by process materials. Effects of such defects as pinholes and pits on coating appearance could be reduced effectively by finishing the surfaces of resin-based composites with pinhole filler, sealant, or pinhole filler and surfacer before painting, and the adhesion between paintcoat and substrate was over 15 MPa. The three process materials can be used for surface finishing of composites before painting and improving of painted surface states since they are consistent with primer, and they have no negative effects on mechanical properties and medium resistance. |
