Abstract

The invention provides a preparation method of a high-temperature-resistant thermoplastic hot melt adhesive for furniture edge sealing, and belongs to the field of hot melt adhesives for furniture edge sealing. The method prepares the high-temperature-resistant hot melt adhesive for furniture edge sealing by rationally designing a ratio of an ethylene-vinyl acetate copolymer (EVA) to an amorphousalpha-olefin copolymer (APAO) to resin to a filler to an antioxidant. The high-temperature-resistant hot melt adhesive for furniture edge sealing provided by the invention has the advantages of no drawing, higher initial adhesion, low odor and better bonding performance, and can meet the requirements for edge sealing of ordinary shaving boards, density boards and laminated wood boards; the hot melt adhesive for furniture edge sealing has better high-temperature resistance, and is suitable for storage and transportation of edge-sealing finished products under higher-temperature conditions (70-90 DEG C), while an ordinary EVA hot melt adhesive for edge sealing can only be used at 50-70 DEG C, so that the method solve the problem that the ordinary EVA hot melt adhesive for edge sealing cannotbe used under high-temperature conditions.

Description

technical field [0001] The invention belongs to the field of hot-melt adhesive for edge sealing of furniture, and in particular relates to a hot-melt adhesive for edge sealing of high-temperature-resistant thermoplastic furniture and a preparation method thereof Background technique [0002] Hot melt adhesive is a kind of thermoplastic adhesive. Within a certain temperature range, the macroscopic physical state of hot melt adhesive changes with the change of temperature, but its chemical properties remain unchanged. This kind of glue has 100% solid content, non-toxic, quick-drying, simple production process, high economic benefits, less equipment investment when customers use it, convenient use and high production efficiency. [0003] Hot-melt adhesives are widely used in all walks of life, especially in the field of furniture edge banding. When using hot-melt adhesives, it is required that the edge-banding hot-melt adhesives used must not have the problem of wire drawing an...
