Problems solved by technology

The main components of the current hot-melt adhesives used for the bonding and compounding of aluminum honeycomb panels are polar group-modified polyethylene and polyethylene-vinyl acetate. The melting point of such materials is generally not higher than 130°C, which limits aluminum Honeycomb panels can only be used in low temperature environments
Otherwise, the melting of the hot melt adhesive layer will damage the aluminum honeycomb panel structure and even cause safety accidents

Abstract

The invention discloses a high-temperature-resistant hot melt adhesive membrane for aluminum honeycomb boards, and a preparation method thereof. The high-temperature-resistant hot melt adhesive membrane for aluminum honeycomb boards is made from, by weight percent, 30-50% of polyester elastomer with above 180 DEG C of melting point, 10-40% of polyolefin copolymer modified by maleic anhydride, 0-40% of polyolefin copolymer, 10-30% of tackifying resin, 0-15% of filler, and 1-3% of functional aid. The components add up to 100%. The high-temperature-resistant hot melt adhesive membrane for aluminum honeycomb boards has the advantages of high adhesion strength, instantaneous resistance to the temperature up to 170-190 DEG C, and long-term resistance to the temperature up to 130 DEG C.

Description

[0001] technical field [0002] The invention relates to a hot-melt adhesive, in particular to a high-temperature-resistant hot-melt adhesive film for bonding aluminum honeycomb panels and a preparation method thereof, belonging to the technical field of polymer hot-melt adhesives. [0003] Background technique [0004] Aluminum honeycomb panel is a multi-layer composite panel composed of metal panel, aluminum honeycomb core, metal bottom plate and polymer adhesive. It has the advantages of light weight, high specific strength, sound insulation and heat insulation performance. Aluminum honeycomb panels can be used as floors and partition walls on trains, floors and ceilings on cars, decks on ships, and curtain walls on buildings. The use of aluminum honeycomb panels It can replace the thick metal aluminum plate to reduce the weight of the material while providing a good decorative effect. [0005] The bonding of aluminum honeycomb panels used structural adhesives such as e...
