Problems solved by technology

[0004] For mobile phone battery aluminum foil packaging sealing hot melt adhesives, the technical requirements are strict. For EVA hot melt adhesives, the low-temperature bonding strength at -20°C cannot be achieved, while for polyurethane hot melt adhesives, the final strength and weather resistance can be satisfied. Requirements, but because it is a moisture curing reactive hot melt adhesive, the curing time is longer, the initial viscosity is weak, the production process is long and the cost is high

Abstract

The invention relates to mobile phone battery aluminum foil packing seal hot melt glue and a preparation method thereof, belonging to the technical field of macromolecular viscose. The method comprises the following steps of: putting sasol wax, tackifying resin C5 hydrocarbon resin and an antioxidant into an electric heating reaction furnace and heating; stirring; adding polyolefin and maleic anhydride modified polyolefin; heating for melting; and vacuumizing, discharging and packing to obtain a mobile phone battery aluminum foil packing seal hot melt glue product. Through the invention, the prepared polyolefin hot melt glue is simple in technology, excellent in high and low-temperature performance, good in initial adhesion and final strength and lower in cost, and prevents carbonization. When in feeding, components with lower viscosity are fed before components with higher viscosity; and the charging order can reduce the rotation load of a stirring paddle in the whole stirring process, reduce the mixing time and save the production cost.

Description

technical field [0001] The invention relates to a hot-melt adhesive for aluminum foil packaging of mobile phone batteries and a preparation method thereof, in particular to a polyolefin hot-melt adhesive and a preparation method thereof, and belongs to the technical field of polymer adhesives. Background technique [0002] Polyolefin hot-melt adhesive is a new type of adhesive, which does not contain any solvents, is pollution-free, has a simple production process, is convenient to use, and has a wide range of uses. It can be used in sanitary materials, packaging, book binding, wood, and automobile industries. [0003] Polyolefin hot melt adhesives are solid at room temperature, and melt into liquid when heated to 120~200°C. They can be used by spraying, rolling and scraping, and become solid when cooled to room temperature. Pressure, cooling and solidification will produce good bonding effect. [0004] For mobile phone battery aluminum foil packaging sealing hot melt adhes...
