The present invention also provides a kind of preparation methods of above-mentioned pervious concrete reinforcing agent, will contain ammonia according to parts by weight
Then siloxanes, oligomeric diol, chain extender and the diisocyanate mixing of base add in nano silicon dioxide mixed mixed
It closes in liquid, obtains the pervious concrete reinforcing agent.
The beneficial effects of the present invention are：
The present invention pervious concrete reinforcing agent, the nano silicon dioxide comprising said ratio, the siloxanes containing amino,
Oligomeric diol, chain extender and diisocyanate are prepared, and in above-mentioned raw materials reaction, utilize nano-silicon dioxide modified reaction
That is, using nano-silicon dioxide modified polyurethanes technology, organic material conduct is used so as to improve simple for the polyurethane of acquisition
Ultimate tensile strength existing for reinforcing agent two is too low and the insufficient problem of reactive silica silicone content；And increase in its raw material proportioning
The content of nano silicon dioxide is added, has made the ultimate tensile strength of pervious concrete reinforcing agent, water resistance, stability, flexibility
It is significantly improved with ageing-resistant performance；In addition, color is transparent after nano-silicon dioxide modified urethane cures, permeable coagulation
Native reinforcing agent can coordinate natural or artificial colored stone to use, and be not required to addition cement, so as to embody original colored stone color,
With more the sense of reality.
