The polyolefin material is nontoxic and odorless, is convenient to process, and has excellent heat resistance, electrical property, insulating property and the like, so that the polyolefin becomes one of the most widely applied materials in daily life. The adhesion of polyolefin materials to metal materials is increasingly in demand in the industries of automobiles, decoration, home appliances and the like. The polyolefin as a nonpolar material is difficult to bond with metal, and is mainly realized by polyurethane, acrylic acid and other liquid adhesives at present, but the liquid adhesives generally contain volatile substances, and have the problems of environmental pollution, inconvenient processing and use and the like.
The hot melt adhesive is widely used as an environment-friendly material convenient to use. In the prior art, hot melt adhesives are also reported for metal and non-metal materials. For example, patent CN114479682a describes a hot melt adhesive film for bonding metal and PVC, which is suitable for polar materials and has poor bonding properties for nonpolar materials, and a method for preparing the same. Patent CN104804659a describes a hot melt adhesive film for metals and nonpolar materials, but the film is complex in preparation process and poor in alcohol and water boiling resistance, and the effect of some relatively difficult-to-stick metals such as copper, zinc, etc. is not described. Patent CN115044311a describes a hot melt adhesive film for bonding between metal and non-metal layers, which uses a thermosetting epoxy adhesive layer, and thus requires a long hot press curing time when in use, which brings many limitations to practical application. Therefore, the existing hot melt adhesive films cannot meet the market demands in terms of bonding metal and polyolefin materials.
