Example Embodiment

[0019] 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.

[0020] 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 .

[0021] 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.

Abstract

The invention discloses a foamable hot melt adhesive compound. According to parts by weight, the prescription of the foamable melt adhesive compound comprises: 10 to 65 portions of polythene, 5 to 20 portions of modified polyvinyl, 5 to 60 portions of EVA, 0.1 to 15 portions of foaming agent, 0.02 to 2 portions of blowing promoter, 0.1 to 0.8 portion of cross linker and 0.5 to 5.0 portions of other accessory ingredients. The foamable melt adhesive compound can be applied to preparing halogen-free and anti-flaming aluminum-plastic composite panels. The product overcomes the defects of the existing pure polythene core materials and halogen core materials and provides a halogen-free and anti-flaming core layer material which has innocuity, harmless and high heat pressing sticking intensity and is used for fire-proof aluminum-plastic composite panels, with anti-flaming performance achieving grade B1; the sticking intensity between the obtained aluminum-plastic composite panels and aluminum panels can achieve more than 135N/25mm, thus reducing the steps of using glue films for compounding; besides, the aluminum-plastic composite panels produced by utilizing the invention have the characteristics of small density, good anti-flaming performance as well as good temperature preservation, sound isolation and heat isolation effects.
