Abstract

The invention relates to hot melt adhesive technical field, and particularly discloses a hot melt adhesive for artificial turf coating and a preparation method thereof. The hot melt adhesive for the artificial turf coating comprises, by weight, 15-50 parts of ethylene-vinyl acetate copolymers, 20-80 parts of propylene-vinyl copolymers, 20-80 parts of polyolefin plastomers and 5-30 parts of amorphous a-olefin copolymers; and the hot melt adhesive is premixed by a high-speed mixer and then squeezed by a twin-screw extruder. The hot melt adhesive is free of solvents and odor, is environmental-friendly, has strong wettability to adherends and can be used for adhering grass tightly, has high peel strength, and has high pullout force of lawn when used as the adhesive resin of the artificial turf coating.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives, in particular to a hot-melt adhesive for artificial turf back glue and a preparation method thereof. [0002] Background technique [0003] Plastic artificial turf is a kind of imitation natural lawn fabric, which has the advantages of easy laying, convenient maintenance, bright color, strong adaptability and long service life. It can be applied to the ground laying and decoration of stadiums, balconies and hotels. The grass silk material of artificial turf is mostly made of polypropylene, nylon, polyethylene and other spinning tufts, and the back material is mostly natural or synthetic ephedra or polypropylene material. The grass silk is woven interlacedly on the bottom back through the weaving holes on the bottom back layer, and the connection reinforcement at the pile is formed by scraping and coating a layer of adhesive on the bottom back. Most of the adhesives currently used are...
