Embodiment 1

[0034] This embodiment provides a polymer modified asphalt with heat storage function, which consists of the following raw materials in parts by weight:

[0035] 100 parts of base asphalt, 10 parts of polymer, 2 parts of functional improver, 0.5 part of stabilizer, 1 part of coupling agent, of which:

[0036] The base asphalt is road petroleum asphalt, the polymer is poly(3,4-dioxyethylenethiophene), the function improver is poly(styrene sulfonic acid), the stabilizer is phenylenedioctyl phosphite, and the coupling agent is It is isocyanate propyl triethoxysilane.

[0037] The preparation method of the polymer modified asphalt with heat storage function of the present embodiment is:

[0038] Step 1. Mix the polymer, function improving agent, stabilizer and coupling agent, then add dimethyl sulfoxide, stir and mix evenly to obtain the polymer modifier;

[0039] The add-on of described dimethyl sulfoxide is that the dimethyl sulfoxide of every 100 weight parts base bitumen is ...

Embodiment 2

[0043] This embodiment provides a polymer modified asphalt with heat storage function, which consists of the following raw materials in parts by weight:

[0044] 100 parts of base asphalt, 4 parts of polymer, 1 part of functional improver, 0.3 part of stabilizer, 0.1 part of coupling agent, of which:

Abstract

The invention provides a polymer modified asphalt with a heat accumulation function, and a preparation method thereof. The polymer modified asphalt is prepared from, by weight, 100 parts of base asphalt, 0.5-10 parts of a polymer, 0.01-2 parts of a functional improver, 0.01-0.5 parts of a stabilizer and 0.01-1 part of a coupling agent. The preparation method comprises the following steps: mixing modifying materials, adding dimethyl sulfoxide, and stirring and mixing above materials until uniformity to obtain a polymer modifier; and adding the polymer modifier to the base asphalt at a high temperature. The modified asphalt can improve the pavement performance of road asphalt, also has a good heat accumulation function, improves the winter pavement performance of the asphalt, reduces the low temperature diseases of a pavement, has good stability, and is nontoxic and anticorrosive. The modified asphalt is environmentally-friendly, nontoxic and anticorrosive modified asphalt, and also has the advantages of wide sources of raw materials, no pollution in the production process, and low price. The preparation method has the advantages of simplicity, low cost and good economic benefit.

Description

technical field [0001] The invention belongs to the field of road engineering materials and relates to asphalt, in particular to a polymer modified asphalt with heat storage function and a preparation method thereof. Background technique [0002] Road ice and snow in the cold season have a certain degree of impact on the entire transportation system, economic system and people's normal outdoor activities and work. In winter, snow and ice on the roads in colder areas of our country are common. According to relevant statistics, 50% of traffic accidents, 71% of major traffic accidents and 65% of direct economic losses in our country occur in bad weather, and it is necessary to strengthen the bad weather conditions. The prevention of traffic safety accidents, and the icing of snow on roads and bridges is an important aspect. And in the winter of our country, there are often traffic accidents caused by ice and snow on the roads, and the consequences are very serious, ranging fro...
