Polyolefin hot melt adhesive composition for woodworking pre-coating and edge sealing

The invention provides a polyolefin hot melt adhesive composition for woodworking pre-coating and edge sealing. The polyolefin hot melt adhesive composition comprises the following components: 70-80 parts of at least one polyolefin polymer; 1-30 parts of an elastomer; 0.1 to 20 parts of a modifier; 0.01 to 3 parts of a catalyst; 0.1 to 1 part of an antioxidant; wherein the elastomer is a thermoplastic elastomer selected from the group consisting of styrenic block copolymers (SBC), thermoplastic vulcanizates (TPV), thermoplastic polyolefins (TPO), copolyesters (COPE), thermoplastic polyurethanes (TPU), copolyamides (COPA), olefin block copolymers (OBC), and combinations thereof; according to the invention, the tackifier and the viscosity modifier in the modifier are used for modifying the bonding strength of the hot melt adhesive, and the phenolic antioxidant is used for ensuring the bonding property of the raw materials under a high-temperature condition, so that the performance of the prepared hot melt adhes
