Description

A kind of high stability modified pitch and preparation method thereof
Technical field
The present invention relates to pitch preparation field, more specifically a kind of high stability modified pitch and preparation method thereof.
Background technology
Matrix pitch is that temperature sensitivity is higher, and the influence factor of climate is larger, and easily softening trickling, causes to drip under high temperature There is track in green road surface；Easily become fragile under low temperature, leads to the cracking of bituminous paving.Therefore it is modified by adding other compositions, And rubber powder is widely used due to deriving from a wealth of sources and modified effect is good, but rubber powder activity is relatively low, with The compatibility of matrix pitch is poor, therefore is being easy to happen sedimentation, and asphalt performance is caused to be deteriorated.
Invention content
The goal of the invention of the present invention is aiming at the deficiencies in the prior art, to provide a kind of high stability modified pitch And preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of high stability modified pitch is grouped as by following groups counted in parts by weight：100 parts of matrix pitch, rubber powder 20- 30 parts, 0.3-0.5 parts of foaming agent, 0.05-0.1 parts of stabilizer, 0.1-0.2 parts of antifoaming agent, 5-10 parts of compatilizer, epoxy resin 10-20 parts.
Above-mentioned foaming agent is sodium bicarbonate.
Aforementioned stable agent is the diaryl disulfide of nitro substitution.
Above-mentioned antifoaming agent is dimethicone.
A kind of preparation method of above-mentioned high stability modified pitch, includes the following steps：
（1）Matrix pitch is heated to 160-180 DEG C, and rubber powder is added and continues to stir 5min；
（2）Stabilizer is added in above-mentioned matrix pitch and continues to stir；
（3）Foaming agent is added in stirring, point 10 additions are primary every 10s additions, after dropwise addition foaming agent crosses 1/2, are added compatible Agent and epoxy resin continue that foaming agent is added dropwise, continue stirring 5 minutes after completion of dropwise addition.
（4）After reaction, it is cooled to 100-120 DEG C of temperature, antifoaming agent is added, antifoaming agent, which divides 10 times, to be added, every 30 seconds Add once, continue stirring after being added dropwise to complete 5 minutes to obtain the final product.
The beneficial effects of the invention are as follows：By increasing foaming agent, pitch is foamed, internal structure is of short duration to become bee Socket, rubber powder, compatilizer and epoxy resin are distributed in three-dimensional honeycomb after expanding, and epoxy resin is full of honeycomb hole Interior, epoxy resin and matrix pitch are combined closely, and the structure after being formed passes through the processing of antifoaming agent, the connection knot formed Structure is squeezed, and structure more crypto set substantially increases the stability of pitch, stabilizer is added in the adding procedure of antifoaming agent, It prevents existing destructurized.
