Problems solved by technology

[0002] With the continuous improvement of people's production and consumption levels, all kinds of bags have become indispensable accessories in people's lives. China is a big producer of bags. In China, there are more studies on the structure of bags, and relatively little research on materials. Less, more materials from other industries are used for production. The main materials of existing hard trolley cases are ABS, PC, PP and other plastic molding materials. During use, the surface is easy to wear when it encounters collision or friction. It will affect the appearance and performance of the trolley case. In the prior art, nano-coating is sprayed on the surface to enhance the scratch resistance of the case surface. However, in actual use, the use environment of the case is relatively complicated, and it may be When used in a high temperature and humid environment, the nano-coating installed on the outside of the box is prone to peeling off, which not only affects the appearance, but also affects the normal use of the box

Abstract

The invention belongs to the technical field of trolley case surface processing and particularly relates to a surface processing method of an anti-scratch plastic trolley case. The method includes: soaking a trolley case base into processing liquid with the temperature being 45-55 DEG C, performing ultrasonic processing for 5-10 minutes, and using washing liquid to wash for 10-20 minutes; sprayingcomposite coating to the washed trolley case base in a working environment of 30-35 DEG C, wherein the thickness of the composite coating is 600-800 micrometers; solidifying the sprayed trolley casebase under the temperature of 60-70 DEG C. Compared with the prior art, the method has the advantages that bonding strength of the coating and the base can be guaranteed effectively, the coating can be fast and stably combined with the surface of the trolley case base, falling off or bubbles can be avoided, the overall strength of the trolley case is increased evidently, and the probability of defective products during production is lowered.
