Description

Anti-static halogen-free flame-retardant circulating packaging box and preparation method thereof
Technical Field
The invention relates to the technical field of packaging box preparation, in particular to an anti-static halogen-free flame-retardant circulating packaging box and a preparation method thereof.
Background
In the processes of loading, unloading, transportation, storage and management of electronic and electric products, extremely high electrostatic voltage can be generated due to mutual friction and vibration, and serious threat is caused to the products. For various static sensitive devices such as electronic elements, integrated circuits, instruments and meters, if materials which are easy to generate static electricity are adopted as packaging materials, the static electricity accumulation generated by friction or electromagnetic induction can generate discharge under proper conditions, so that product failure or part of elements are damaged, and great economic loss is caused. Therefore, as people's understanding of electrostatic hazards continues to deepen, antistatic packaging becomes more and more important. Various electronic products become more and more delicate, the electrostatic sensitivity of microelectronic products is more improved along with the miniaturization and integration of the products, and the demand on various antistatic packages is higher and higher. At present, electronic and electric appliance manufacturers generally adopt cartons as packing materials for storage and transportation, and match with anti-static packing bags to realize short-time protection. However, as the logistics industry is more competitive, each logistics enterprise pays more attention to efficiency, resulting in the phenomenon of violent sorting and random throwing of goods, and the paper packing box is almost used once, which causes a great deal of loss. And a few electronic and electric appliance manufacturers adopt the anti-static hollow plastic board boxes, but the anti-static hollow plastic board boxes are limited in bearing, are only suitable for light loads of several kilograms, and cannot provide effective protection for products of dozens of kilograms.
Therefore, the applicant of the patent researches and develops the packaging box capable of providing all-around protection for the electronic and electric products, such as strong pressure resistance, water and moisture resistance, static electricity resistance, flame retardance and the like, and can effectively protect electronic elements in the packaging box from being damaged by static electricity, being not damaged by collision and fire risks, so that loss and waste of the electronic and electric products in the production and transportation processes are reduced, the packaging box can be recycled for many times, the purposes of reducing the packaging cost and improving the benefit are achieved, and the packaging box has positive practical significance.
Disclosure of Invention
The invention aims to provide an anti-static halogen-free flame-retardant circulating packaging box and a preparation method thereof, and aims to meet the requirement of protection in the turnover process of electronic and electric products in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
an antistatic halogen-free flame-retardant circulating packing box and a preparation method thereof are characterized by comprising an upper surface layer and a lower surface layer of a composite material and a foam core material lining layer.
