Environment-friendly hot melt adhesive for Velcro compounding and preparation method thereof

The invention discloses an environment-friendly hot melt adhesive for Velcro compounding. The environment-friendly hot melt adhesive comprises the following components in percentage by mass: 10-16% ofan environment-friendly plasticizer, 28-35% of a high-molecular polymer, 47.5-60.8% of hydrogenated petroleum resin, 0.8-1% of an antioxidant and 0.2-0.5% of an ultraviolet absorber UV326, wherein the high-molecular polymer comprises one or more of SIS rubber with a high melt index, SBS rubber and SSBR rubber, the melt index of the SIS rubber with the high melt index is 11-40 g/10 min, and the content of styrene is 0-44%. According to the environment-friendly hot melt adhesive disclosed by the invention, the SBS rubber and the SIS rubber are introduced, the environment-friendly hot melt adhesive has excellent peel strength, temperature resistance and cohesion strength, has excellent adhesion to a compact or difficult-to-permeate base material, maintains the bonding strength of the Velcroin a low-temperature envir
