Glue technology, carries out depth depolymerization reaction to realize, the rubber such as tire is big mainly for 36 mesh above vulcanized rubber powder particles
Use sulfur-crosslinked keys contained in sulphur/accelerator vulcanizing system, its network structure mainly include single sulphur, double sulphur, many sulphur with
And the sulfur-crosslinked key of ring-type, the dissociation energy of these carbon-sulfide linkage (- C-Sz-C-) and sulphur-sulfide linkage (- C-S-S-C-) cross-bond is relatively low,
Cleavage reaction easily occurs during depolymerization reaction, generation low molecular compound and low molecule free radical are decomposed, so as to prepare
Paste liquid rubber, can solve compatibility of the rubber powder in pitch and can admix problem with vast scale；From technique
On, liquid rubber is added in emulsified asphalt, is to add liquid rubber after relatively stable emulsified asphalt is formed mostly, is showed
Field processing is used, you can be not understood as entering in emulsified asphalt to use by liquid rubber " blending ".And the present invention is by technique
Improve, semisolid paste liquid rubber is well dissolved in as modifying agent in pitch, form stable compatible system, then to drip
Green grass or young crops is modified emulsification, and high solid emulsified modified asphalt can be made, along with SBS is composite modified, makes emulsified asphalt performance notable
Improve, stability enhancing is easy to long-distance transportation to store, is more widely applied, and damaged tire is also utilized effectively, simultaneously
Greatly reduce the production cost of modified pitch.
