Foamable hot melt adhesive composition and uses thereof

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.

Description

technical field [0001] The invention relates to a core layer material of a halogen-free flame-retardant aluminum-plastic composite board used for building material decoration, in particular to a foamable hot-melt adhesive composition used for the core material of a halogen-free flame-retardant aluminum-plastic board and its application. In the manufacturing method of aluminum-plastic panel. technical background [0002] The fire-resistant aluminum-plastic panel mainly has a five-layer structure, including three-layer boards, which are the core layer of inorganic flame-retardant materials in the middle, and aluminum metal plates on the front and back. [0003] At present, the core materials of aluminum-plastic panels used in the building materials market mainly include pure polyethylene materials and halogen-containing flame-retardant core materials. The former pure PE core materials are currently sold in large quantities on the market and used as ordinary aluminum-plastic co...

AI Technical Summary

Problems solved by technology

However, since neither of the above two patents uses a foaming agent, the aluminum-plastic panel used for manufacturing consumes a lot of PE, and the cost is relatively high. At the same time, the thermal insulation, sound insulation and heat insulation performance are slightly poor.
