Coating composition used for containers and accessories and coating process

一种用于集装箱和配件的涂层组合以及涂装工艺

Abstract

The invention discloses a coating composition used for containers and accessories and a coating process. The coating process comprises the following steps: performing surface treatment on the containers and accessory substrates and removing oil fouling and rustiness attached to the surfaces of the accessory substrates to enable the surface roughness of the substrates to be 1-50 microns; performing surface pretreatment on the containers and the accessory substrates to improve the adhesive force and the salt spray resistance property of a coating; coating undercoat on the accessory substrates after the pretreatment; finally, coating finishing coat on the accessory substrates coated with the undercoat. According to the invention, the protective coating formed on the containers and the accessories has more excellent properties in comparison with the existing container coating and can meet the mechanical properties and salt spray resistance required by the accessories. The coating process can replace the current hot galvanizing technology which is not environmentally friendly and reduces damage of heavy metal to the environment.
本发明公开了一种用于集装箱和配件的涂层组合以及涂装工艺,首先对集装箱及配件底材进行表面处理,在底材表面上除去油污和锈蚀,使得表面粗糙度在1-50微米;接着对集装箱及配件底材进行表面预处理,提高涂层的附着力和耐盐雾性能;再接着在已经预处理好的底材上涂装底漆;最后在已涂装好底漆的底材上涂装面漆。本发明在集装箱和配件形成的保护涂层具有比目前集装箱涂层更为优异的性能,能满足配件所需的力学及耐盐雾性能,其涂装工艺可以取代目前不环保的热镀锌工艺,减少重金属对环境的破环。
