Embodiment

[0051] First, the preparation of colorless binder: it is based on petroleum resin (Ss) and mineral oil (Ks), adding one of SBS or EVA as a modifier, mixed according to a certain proportion and heated to 150°C It is in a molten state at a temperature of ~170°C, so that the solid SS is fully swollen in Ks, and then the components are mixed with each other through high-speed shearing to form a uniform mixture to make a colorless cement. SS is solid at room temperature, with high cohesiveness, light color, and good thermal stability, but it is brittle and hard, and its impact resistance is poor, so it cannot be used alone as a road cement. As a by-product of petroleum, KS is viscous and fluid at room temperature, has good miscibility with SS, and has good plasticization and toughness. At a temperature of 150°C to 170°C, the molten SS swells in KS to form a mixture, which reduces the brittleness of solid SS and enhances plasticity and toughness. The mixed cement can meet the genera...
