The invention aims at providing a method for improving epoxy coating combining strength. Firstly, the base surface is subject to surface derusting treatment; secondly, a base is subject to ordinary pressure air plasma treatment; and finally, a coating is prepared according to the conventional epoxy resin preparing process. The bonding strength of the prepared coating can be increased by about 1-1.5 times under the condition that raw materials and the process conditions are not changed, and falling or scratching of the coating is effectively prevented; at an occasion with epoxy resin as a bonding agent, as the bonding strength of the epoxy resin and the base surface is high, the bonding force of the epoxy resin bonding agent can be greatly improved. The method solves the problem that in theprior art, an epoxy resin coating is prone to stripping is solved. 本发明的目的是提供种提高环氧涂层结合强度的方法，首先对基体表面进行表面除锈处理，然后对基体进行常压空气等离子处理，最后按照常规的环氧树脂制备工艺制备涂层，制备涂层的粘结强度在原料和工艺条件不变的情况可增大约1～1.5倍，有效地防止了涂层的脱落或划伤；对环氧树脂作为粘结剂的场合，由于环氧树脂与基体表面的粘结强度高，
