preparation example Construction

[0029] The present invention also provides a method for preparing the above-mentioned odor-cleaning colored asphalt composition, the steps are as follows:

[0030] (1): Add base oil according to the weight percentage ratio, heat to 165°C-175°C, add thermoplastic styrene-butadiene rubber and stir to melt;

[0031] (2) After completely dissolving, add petroleum resin, anti-aging agent, viscosity-increasing additive, odor inhibitor and surfactant in sequence, stir and mix evenly, and develop for 1 hour to prepare the odor-cleaning colored asphalt composition.

Embodiment 1

[0034] Take by weight 40 parts of aromatic hydrocarbon oil, 15 parts of C 9 Petroleum resin, 20 parts of styrene-butylene-styrene segmented copolymer, 1 part of anti-aging agent, 0.5 part of tackifier, 0.5 part of odor inhibitor and 0.8 part of surfactant.

[0035] Heat the aromatic oil to 165°C-175°C, add 20 parts of styrene-butylene-styrene block copolymer and stir to melt;

[0036] After complete dissolution, add 15 parts of C 9 Petroleum resin, 1 part of anti-aging agent, 0.5 part of tackifier, 0.5 part of odor inhibitor and 0.8 part of surfactant. After stirring and mixing evenly, develop for 1 hour, and the clean-odour colored asphalt composition is prepared. See Table 2 for conventional technical indicators for testing colored asphalt.

Embodiment 2

[0038] Take by weight 45 parts of heavy oil minus secondary fission heavy oil, 18 parts of C 9 Petroleum resin, 30 parts of styrene-butylene-styrene block copolymer, 2 parts of anti-aging agent, 0.5 part of tackifier, 1 part of odor inhibitor and 0.5 part of surfactant.

[0039] Heat the heavy oil to 165°C to 175°C, add 30 parts of styrene-butylene-styrene block copolymer and stir to melt the heavy oil;

[0040] After complete dissolution, add 18 parts of C 9 Petroleum resin, 2 parts of anti-aging agent, 1 part of tackifier, 1 part of odor inhibitor and 0.5 part of surfactant. After stirring and mixing evenly, develop for 1 hour, and the clean-odour colored asphalt composition is prepared. See Table 2 for conventional technical indicators for testing colored asphalt.

Abstract

The invention provides an odorless color asphalt composition, which is prepared from the following components by weight: 40-50 parts of base oil, 15-20 parts of a petroleum resin, 20-30 parts of a thermoplastic styrene-butadiene rubber, 1-2 parts of an anti-aging agent, 0.5-1 part of a tackifying aid, 0.5-1.2 parts of an odor inhibitor, and 0.5-0.8 part of an interface active agent. According to the present invention, the odorless color asphalt composition acts through the odor inhibitor and the interface active agent so as to reduce the formation and volatilization of H2S, SO2, NOX and otherasphalt flue gases during color asphalt production and construction and significantly eliminate the odor, wherein the asphalt performance is not significantly changed, and the environment protection and the health of personnel can be easily achieved. The present invention further provides a preparation method of the odorless color asphalt composition.

Description

technical field [0001] The invention belongs to the field of road engineering materials, in particular to an odor-cleaning colored asphalt composition and a preparation method thereof. Background technique [0002] Colored asphalt pavement has the obvious effect of beautifying the road environment, better coordination with the surrounding architectural art, beautifying the city, inducing traffic, improving road traffic safety, and greatly improving the monotony of ordinary black pavement, so it is becoming more and more The more it is used in areas such as new roads, squares, and traffic guidance sections of high-grade highways in iconic cities, it can reflect the characteristics and style of a country or a city. At present, colored asphalt pavement has been built in various degrees in various parts of our country. [0003] However, during the production and construction of colored asphalt, a large amount of asphalt fume will be produced, which will have a serious impact ...
