Abstract
The invention is a sealant special for sealing cracks of bituminous pavement, it contains (in weight share): petroleum pitch 100 shares, SBS 9-15 shares, tackifying resin 4-10 shares, antiageing agent 0.2-1 share, synthetic rubber 0-4 shares, stabilizer 0.15-0.45 share, softening agent 2-16 shares, viscosity-regulator 2-15 shares, antistripping agent 0.2-0.5 share, and reinforcing agent 35-60 shares. It has weak temperature sensitivity, strong adhesion and good elasticity.
Description
Technical field
The present invention relates to a kind of sealing adhesive for crack on road that is exclusively used in the sealing of the asphalt pavement crack cementation of fissures.
Background technology
Traditional pavement crack cementation of fissures sealing is that common petroleum pitch is poured in the crack through heat fused.Because the bituminous temperature sensibility is strong, deliquescing in summer, trickling are taken away by wheel, the hardening in winter, become fragile, and follow the string, and ftracture, and need 1 year cementation of fissures again, and be very uneconomical.
The present invention is directed to above problem, a kind of new formula technique is provided, its purpose is to overcome the deficiency that pitch is used for the pavement crack sealing, a kind of high performance sealing adhesive for crack on road is provided, can softening transform during sealing glue high temperature, do not taken away by wheel, having very high elasticity during low temperature does not ftracture, can be with fissured harmomegathus generation elastic deformation, cohesive force is strong, seals pavement crack all the time.
Summary of the invention
The present invention's prescription has following feature (by weight):
Petroleum pitch: 100 parts,
SBS:9-15 part,
Tackifying resin: 4-10 part,
Anti-aging agent: 0.2-1 part,
Synthetic rubber: 0-4 part,
Stablizer: 0.15-0.45 part,
Tenderizer: 2-16 part,
Viscosity modifier: 2-15 part,
Antistripping agent: 0.2-0.5 part,
Toughener: 35-60 part
Use molecular weight to be not more than 300,000 linear and star shaped SBS mixture in the prescription, overcome the deficiency of single a kind of form on temperature sensitivity, low temperature flexibility, elasticity, adjust the two proportioning, be fit to the pavement performance of different weathers.
Be different from modifying asphalt, high molecular polymer SBS and synthetic rubber content height in the sealant formula of the present invention, in use emanate between superpolymer and pitch, cause the seal gum cohesive strength to descend, through the wheel spreading, glue and pavement crack break away from, seal failure, product same segregation phenomenon that takes place in storage process is packed destroyed simultaneously.So the sulfide that the present invention has adopted benzene has improved high-temperature stability, cohesiveness, the package stability of seal gum as increasing the stablizer that superpolymer and pitch mix.
The tackifying resin that the present invention adopts is the mixture of aliphatic petroleum resin, aromatic petroleum resin and polyisobutene, and its ratio (weight meter) is: 2.5-6.5 part: 1-3 part: 0.5 part.Anti-aging agent is T501, and synthetic rubber is a divinyl rubber, and tenderizer is that alkane oil, viscosity are 32-46mm
2/ s, viscosity modifier is a rubber powder, antistripping agent is the mixture of poly-alkylene base glycol, alkoxide aliphatic polyamines and alkylamine, and toughener is the mixture of any one or two kinds in 400-600 order talcum powder, 400-600 order lime carbonate, the 200-300 order limestone powder.
By the road seal gum that prescription of the present invention makes, strong, the high-temperature stable of cohesive force, softening temperature be more than 90 ℃, the low temperature softness, and resilience is good, and 25 ℃ of recovery of elasticity reach more than 98%.
