Problems solved by technology
 The present invention is a foamable hot-melt adhesive composition for halogen-free flame-retardant aluminum-plastic plate core material. Calculated in parts by weight, the formula contains the following components: 10 to 65 parts of polyethylene, modified ethylene polymer 5-20 parts, EVA 5-60 parts, foaming agent 0.1-15 parts, foaming auxiliary agent 0.02-2 parts, cross-linking agent 0.1-0.8 parts, other auxiliary agents 0.5-5.0 parts.
 Among them, polyethylene is a combination of one or more of high-pressure polyethylene, high-density polyethylene or linear low-density polyethylene, and its melt flow rate is 0.1-15g / 10min, preferably 0.15-7g / 10min .
 The modified monomer of the modified ethylene polymer is selected from maleic acid (anhydride) and its esters, acrylic acid and its esters, styrene and its derivatives, methacrylates and glycidyl methacrylate Any one or a combination of two or more. Maleic acid (anhydride) and its esters are preferred.
