Abstract
The invention relates to the technical field of asphalt additives, and especially relates to an application of active calcium carbonate in an SBS asphalt stabilizer. The application concretely comprises the following steps: 1) weighing sulfur powder, SBS, styrene butadiene rubber, octadecyl amine ethoxylate ether, stearyl trimethyl ammonium chloride, polyethylene resin and nanometer zinc oxide, adding the weighed substances into a grinding machine, heating above added substances to 110-130 DEG C, and shearing and grinding the heated substances for uniform mixing; and 2) continuously adding active calcium carbonate and nonylphenol polyoxyethylene ether, heating the added substances to 170-190 DEG C, shearing and grinding the heated substances for uniform mixing, carrying out extruding granulation through a twin-screw extruder, and pelletizing the granulated substance to prepare the SBS asphalt stabilizer. The use of the active calcium carbonate in the preparation of the SBS asphalt stabilizer improves the dispersibility and the compatibility of the SBS asphalt stabilizer in SBS modified asphalt, thereby improving the stability of the SBS modified asphalt.
Description
Technical field
The invention belongs to asphalt additive technical field, more particularly to a kind of activated Calcium carbonate is in SBS asphalt stabilizers
Application.
Background technology
With the continuous development of various countries' communication, the continuous improvement of the road surface requirement of highway, for laying road surface
The quality requirement of pitch also constantly increases.Current pitch causes its high temperature stability performance, water stable due to due to its component
Property and antiskid performance etc. cannot all meet the needs of growing highway pavement laying.
In order to solve these problems, some modified pitch are continued to bring out, for SBS modified pitch, due to pitch and
The modifying agent physical difference opposite sex is larger, and traditional SBS modified pitch is uniformly divided SBS by physical methods such as stirring, shearings
Dissipate in pitch, SBS does not occur obvious chemical reaction with pitch, only miscible in physical significance, its stability
Or the needs on high request road surface can not be met.
