However, since the outbreak of the "poison track" event, the conventional on-site paving type track has been gradually eliminated by the market, and is replaced by various prefabricated plastic tracks, wherein the prefabricated plastic track using SEBS as the base material has been widely paid attention to in the industry because of its excellent environmental protection, motility and unique full recyclability.
The laying process of the prefabricated plastic track is an adhesion composite system formed by the adhesive, at present, the most common two-component polyurethane adhesive is formed by a resin matrix with hydroxyl or amino and isocyanate, the two components are uniformly mixed and then coated between the ground and the track during laying, and the hydroxyl or amino reacts with the isocyanate to generate carbamate or urea bonds to form the track polyurethane adhesion composite system. However, the bonded composite systems also have problems, especially poor adhesion, which plagues the stability and durability of the track paving process. The key point of the problem is that the polarity of the SEBS-based plastic track is small, polyurethane, especially generated carbamate or urea bonds, is large, and the polyurethane cannot form firm adhesion due to the polarity difference, so that how to improve the adhesion of the SEBS-based track polyurethane adhesion composite system is an urgent problem to be solved.
