Those skilled in the art person of continuously attempting to is modified to emulsified asphalt.
In modified emulsifying asphalt using it is more be polymer modification emulsified asphalt, wherein rubber-like modified emulsifying asphalt is produced
Product, because the molecular weight rubber asphaltene molecules amount more maximum than in pitch is much bigger, the motion energy of rubber molecular chain is very high,
Emulsified asphalt is demulsified initial stage, the constraint with regard to that can break through asphaltene molecule, is passed through from asphaltene molecule and is cross-linked with each other to form grid structure,
And pitch is then evenly dispersed in rubber molecule network structure, a structure completely stablized is formed.But current polymer changes
Property pitch is generally that physics is miscible, its compatibility between pitch, is not well solved always, its content of modifier is also difficult
To improve, and it is poor to deposit stability.
In view of the above problems, except common polymer modifiers, response type asphalt modifier is also growing.Instead
Answer type Production Process of Modified Bitumen simple, after pitch is dissolved, be directly added into response type modifying agent, it is multiple without shearing, being swelled etc.
General labourer's skill, because it belongs to chemical modification, therefore obtained modified pitch compatibility is good, storage stability.Chinese patent (CN
A kind of chemical modified bitumen cementitious matter and preparation method thereof 105111755A) is disclosed, RET and PPA is added in matrix pitch
Two kinds of response type asphalt modifiers, improve the high-temperature behavior of pitch, but its cryogenic property is not improved.
