Abstract

The invention discloses a hot melt adhesive and a production method thereof, and belongs to the technical field of chemical industry. The hot melt adhesive is prepared from, by weight, 10-20 parts ofdibutyl phthalate, 5-10 parts of triethanolamine, 4-10 parts of epoxy propane phenyl ether, 2-8 parts of benzisothiazolone, 2-10 parts of polyurethane resin, 5-9 parts of hydroxypropyl distarch phosphate, 2-10 parts of N-methylpyrrolidone, 3-9 parts of peroxide hydroxyl diisopropylbenzene, 1-5 parts of Furfuryl alcohol resin, 4-10 parts of antioxidants and 2-6 parts of cross-linking agents. The hot melt adhesive has excellent hot melt performances and cohesiveness, can be normally used at the high temperature and is simple to product, low in cost and excellent in performance.

Description

technical field [0001] The invention relates to a hot-melt adhesive and a preparation method thereof, belonging to the technical field of chemical industry. Background technique [0002] Adhesive refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesive, which has the characteristics of continuous stress distribution, light weight and low process temperature. Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Glue is developing the fastest in modern times and has a wide range of application industries. There are many classification methods of adhesives, which can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitive type, etc. according to the application method; according to the application object, it can be divided into structural type, non-configuration or special adhesive; the connect...
