Abstract

The invention discloses a polystyrene-b-polyisoprene / tackifying resin composite rubber particle and a preparation method and application thereof. The composite rubber particle comprises polystyrene-b-polyisoprene and tackifying resin components. The preparation method includes: preparing polystyrene-b-polyisoprene sol in an anionic polymerization system, adding tackifying resin into the sol, dissolving, mixing and performing condensation, solvent removal and granulation to obtain the polystyrene-b-polyisoprene / tackifying resin composite rubber particle. The composite rubber particle is free ofcold flow and adhesion at the room temperature and has a great self-adhesion performance under the action of rubber oil, and the tackifying resin composite rubber particle is great in resistance to high and low temperatures and excellent in sand and concrete surface adhesion performance in high-wax high-softening-point asphalt modification, is also high in water resistance and ductility and realizes expansion of high-wax asphalt application.

Description

technical field

[0001] The invention relates to a polystyrene-b-polyisoprene / tackifying resin composite rubber particle and a preparation method of the composite rubber particle, in particular to polystyrene-b-polyisoprene / tackifying resin The composite rubber particles are used in modified viscosifying building asphalt materials, and belong to the field of polymer synthesis and modified asphalt. Background technique

[0002] Many changes have taken place in modern roads and roads, which require improving the flow resistance of the pavement, that is, the ability to resist rutting at high temperatures; improve flexibility and elasticity, and the ability to resist cracking at low temperatures; improve wear resistance and prolong service life. Modern buildings generally use long-span prestressed roof panels, requiring roof waterproof materials to adapt to large displacements, more resistant to harsh high and low temperature climate conditions, better durability, self-adhesive, ...
