Example Embodiment

[0038] Example one

[0039] Catalytic slurry: 540 grams,

[0040] Emulsifier: 15 grams, PC-1310

[0041] Water: 445 grams, clear and transparent tap water without impurities

[0042] The catalytic oil slurry is firstly oxidized into a shallow oxidation oil slurry through an oxidation kettle. The process conditions of shallow oxidation are: oxidation temperature 180℃, air volume 8L / min·kg, oxidation time 5h. The penetration of the oxidized oil slurry is 185 1 / 10mm , Keep the lightly oxidized oil slurry at 130°C for later use. Add the emulsifier to the water and stir to make a soap solution and heat it to 60°C for later use. After the hot soap liquid is added to the emulsification equipment and circulated, the standby shallow oxidized oil slurry is added, and the cyclic shearing is performed for 3 minutes to obtain the road permeable layer oil product.

Example Embodiment

[0043] Example two

[0044] Catalytic slurry: 520 grams,

[0045] Emulsifier: 10 grams, FS-C01

[0046] Water: 470 grams, clear and transparent tap water without impurities

[0047] The catalytic oil slurry is firstly oxidized into a shallow oxidation oil slurry through an oxidation kettle. The process conditions of shallow oxidation are: oxidation temperature 200℃, air volume 10L / min·kg, oxidation time 6h. The penetration of the oxidized oil slurry is 166 1 / 10mm , Keep the lightly oxidized oil slurry at a temperature of 135°C for later use. Add the emulsifier to the water and stir to form a soap solution and heat it to 60°C for later use. After the hot soap liquid is added to the emulsification equipment and circulated, the shallow oxidized oil slurry to be used is added, and the circulation shearing is performed for 3 minutes to obtain the road permeable layer oil product.

Example Embodiment

[0048] Example three

[0049] Catalytic slurry: 560 grams,

[0050] Emulsifier: 18 grams, JY-R4

[0051] Water: 422 grams, clear and transparent tap water without impurities

[0052] The catalytic oil slurry is firstly oxidized into a shallow oxidation oil slurry through an oxidation kettle. The process conditions of shallow oxidation are: oxidation temperature 200℃, air volume 8L / min·kg, oxidation time 4h. The penetration of the oxidized slurry is 197 1 / 10mm , Keep the lightly oxidized oil slurry at 130℃ for later use. Add the emulsifier to the water and stir it to form a soap solution and heat it to 65°C for later use. After the hot soap liquid is added to the emulsification equipment and circulated, the shallow oxidized oil slurry to be used is added, and the circulation shearing is performed for 3 minutes to obtain the road permeable layer oil product.

Abstract

The invention provides road prime coat oil which comprises components in percentage by mass as follows: 50%-58% of mildoxidation slurry oil, 0.5%-2.5% of an emulsifier and the balance of water. The invention further discloses a preparation method of the road prime coat oil. The road prime coat oil can meet the technical requirements for emulsified asphalt prime coat oil for routine roads while the production cost can be lower than the emulsified asphalt prime coat oil by 20%.

Description

technical field [0001] The invention relates to a road penetrating layer oil, and also relates to a preparation method of the road penetrating layer oil. Background technique [0002] Road penetrating layer oil is a liquid material with penetrating effect, which is mainly used for the transition layer between the base layer and the asphalt layer of the highway asphalt pavement. After spraying the penetrating oil on the asphalt pavement base, a certain depth of thin layer can be formed on the surface of the base, which mainly plays the role of preventing the base from permeating, consolidating the surface of the base, and making the base and the asphalt surface well connected. "Technical Specifications for Construction of Asphalt Pavement on Highway" JTG F40-2004 clearly stipulates that all types of base layers of asphalt pavement must be sprayed with penetrating oil. [0003] At present, dilute asphalt with good permeability, emulsified asphalt, coal tar, etc. are generally...
