Abstract
A sealing adhesive for repairing the crack on road is prepared from petroleum asphalt (60-85%), SBS (5-20%), viscosity increasing resin (5-20%), anti-stripping agent for asphalt (0.1-4%), anti-ageing agent for rubber (0.2-1.4%) and toluene (10-30%). Its advantages are high adhesion and elasticity and better temp sensitivity.
Description
Technical field
The present invention relates to the repairing road cracks material, particularly relevant with a kind of asphalt roads crack repairing seal gum of thermoplastic elastomer modification that utilizes.
Background technology
Traditional maintenance of surface is that common petroleum pitch heating and melting is poured in the crack, and owing to bituminous elasticity, cohesiveness, thermonasty equal difference, crack again in the clinking place in very short time, must safeguard again, very uneconomical.The object of the present invention is to provide a kind of modifying asphalt, can bear heat and winter severe cold in summer with favorable elasticity, cohesiveness and thermonasty, can high-temperature softening deformation, can not ftracture ageing-resistant performance excellence, long service life again in winter.
Summary of the invention
The present invention is to be base-material with petroleum pitch, and SBS is a properties-correcting agent, and has mixed tackifying resin, development of anti stripping agent for asphalt, anti-aging agent and toluene.
Prescription of the present invention is as follows:
Petroleum pitch: 60%-85% SBS:5%-20% tackifying resin 5%-20% development of anti stripping agent for asphalt: 0.1%-4% rubber antioxidant: 02%-1.4% toluene: 10%-30%.(above prescription all by weight 100%)
By the road seal gum good heat resistance that this prescription and method make, 50 ℃ are indeformable, the low temperature softness, and-28 ℃ of not embrittlement, 20 ℃ of adhesion tension force 500%, bonding force is strong, melt viscosity 2000 ± 500mpa.s/190 ℃.
Embodiment
Further specify the present invention below in conjunction with embodiment.
Embodiment 1
Petroleum pitch: 100g SBS:5g tackifying resin: 6g development of anti stripping agent for asphalt: 0.3g rubber antioxidant: 0.5g toluene: 15g.Seal gum product by above-mentioned prescription gained through its performance index of lab investigation is: 86 ℃ of melt viscosities 1600 of softening temperature (190 ℃) brittle point＜-28 ℃ adhesion tension force〉500%.
Embodiment 2
Petroleum pitch: 100g SBS:8g tackifying resin: 12g development of anti stripping agent for asphalt: 0.8g rubber antioxidant: 0.5g toluene: 35g.Seal gum product by above-mentioned prescription gained through its performance index of lab investigation is: 86 ℃ of melt viscosities 1600 of softening temperature (190 ℃) brittle point＜-28 ℃ adhesion tension force〉500%.
