Sealed energy-absorbing structure and packing box with the structure

Abstract

The application relates to an electroless plating process, specifically a sealed energy-absorbing structure and a packing box with the structure. The main structure of the packing box is divided into outer skin, foam interlayer, metal skeleton and inner skin. The composite coating is prepared by chemical plating on the surface of the metal skeleton, and the composite coating is prepared by chemical plating on the surface of the foam interlayer. The above composite structure can produce Energy absorption and sealing effect. Applying ultrasonic vibration during the preparation process can make the added molybdenum disulfide nanoparticles uniformly dispersed in the plating solution and avoid agglomeration. When the box receives impact and external force, the surface contact between the metal skeleton and the foam interlayer is changed to a point contact, the stress propagation is weakened, and there is a gap between the chemical plating on the surface of the metal skeleton and the chemical plating on the surface of the foam interlayer, which can further prevent In addition, due to the presence of raised molybdenum disulfide particles on the surface of the coating, it has self-lubricating properties and reduces the friction between particles.

Description

technical field [0001] The application relates to an electroless plating process, in particular to preparing a sealed energy-absorbing structure by electroless plating. Background technique [0002] Electroless plating is a new type of surface treatment technology, which has attracted increasing attention because of its simple process, energy saving and environmental protection. Electroless plating has a wide range of applications, uniform coating and good decoration. In terms of protection performance, it can improve the corrosion resistance and service life of the product; in terms of functionality, it can improve the wear resistance, electrical conductivity, lubrication performance and other special functions of the workpiece, so it has become a development of surface treatment technology in the world.

Problems solved by technology

[0003] There are two kinds of existing packaging box production methods: one is the relatively mature hand lay-up molding process (that is, wet method), and the other is the vacuum-assisted molding process (that is, dry method), wet method. At present, there are many packaging boxes for a certain equipment It is molded by glass fiber plus resin introduction process, which has the disadvantages of heavy weight / low rigidity and poor sealing performance of the molded product
