Problems solved by technology

The cost of decolorizing petroleum asphalt is expensive, the process is complicated, and it is difficult to produce in large quantities. The decolorized substance also has a certain color, which is not easy to be colored. The quality of the obtained cementitious material is uncontrollable. It is easy to crack at low temperature and unstable at high temperature. Use in areas with different climatic conditions and different rainfall is not conducive to the promotion of colored cementitious materials

Embodiment 1

[0027] A kind of colorless binder, comprising 60kg rubber oil, 37kg carbon five petroleum resin, 3kg ethylene-vinyl acetate copolymer, is prepared according to the following steps:

[0028] Step 1: Inject 60kg of rubber oil into the reactor and heat up to 145°C-155°C;

[0029] Step 2, add 37kg of C5 petroleum resin to the reaction kettle with a screw conveyor, keep the temperature at 145°C-155°C, and stir until the reactants are completely melted;

[0030] Step 3: put 3kg of ethylene-vinyl acetate copolymer into the reaction kettle, stir, and swell for 5-7 hours; mix the components with each other to form a uniform mixture, and obtain the finished product of colorless cement.

[0031] When in use, the colorless cement is transported to the mixing building through the cleaned asphalt pump and pipeline to complete the production task.

Embodiment 2

[0033] A kind of colorless binder, comprising 58kg rubber oil, 39kg carbon five petroleum resin, 3kg ethylene-vinyl acetate copolymer, is prepared according to the following steps:

Abstract

The invention discloses a colorless cementing material which is prepared by mixing the following components in parts by weight: 43-70 parts of base oil, 28-50 parts of modifier and 2-7 parts of high-molecular copolymer. The invention also discloses a preparation method of the colorless cementing material, which comprises the following steps: sequentially mixing rubber oil, C5 petroleum resin and ethylene-vinyl acetate copolymer, and heating to a molten state until the C5 petroleum resin and ethylene-vinyl acetate copolymer are sufficiently swollen and mixed in the rubber oil to form a uniform mixture, thereby obtaining the colorless cementing material. The colorless cementing material disclosed by the invention has the advantages of greatly lowered cost, simple preparation process, favorable adhesiveness with aggregate, favorable high-temperature stability, low cracking tendency at low temperature, favorable water damage resistance, higher viscosity than imported pitch, stable quality and accessible raw materials, is suitable for regions with different temperatures, climatic conditions and rainfall amounts, and is easy to prepare.

Description

technical field [0001] The invention relates to a colorless cementing material and a preparation method thereof. Background technique [0002] The research and application of colored cementitious material pavement began in the early 1980s in my country, but with little effect, and there are still few applications on the road. In the 1990s, red iron oxide was added to black asphalt to produce colored cementitious materials, but the color of the road surface of this colored cementitious material was dull and could not meet the aesthetic requirements. Moreover, the production of colored binder pavement with black asphalt can only pave dark red pavement, and pavement of other colors cannot be produced. In recent years, colored cementitious concrete pavement has been used more and more in places such as highways, roads or squares, which has aroused people's interest and attention, and is regarded as a "new green building material" by the global engineering community. The colore...
