Abstract

The invention discloses a combined hot melt adhesive net film and a preparing technology thereof, and particularly relates to a combined hot melt adhesive net film used for bonding metal and nonpolar materials and a preparing technology of the combined hot melt adhesive net film. Due to the fact that the specific formula is adopted, the polar polyamide hot melt adhesive and the nonpolar polyolefin including a bulking agent are effectively fused. According to the combined hot melt adhesive net film prepared through the technology, the bonding strength of the combined hot melt adhesive net film is high, bonding is durable and stable, and the combined hot melt adhesive net film is particularly suitable for bonding and combining of stainless steel, aluminum, copper and other metal materials with polyethylene, polypropylene and other nonpolar polymers. Meanwhile, according to the preparing technology, the process from raw material preprocessing to final finished combined hot melt adhesive net film preparing is finished in one set of production procedures, the production fault can be greatly reduced, the production efficiency is high, and cost is low.

Description
