Embodiment 1

[0053] This embodiment is a self-healing viscous oil, which is prepared from the following raw materials by weight: Component 1 includes: 94 parts of petroleum asphalt, 2 parts of styrene-butadiene-styrene copolymer , 4 parts of polyolefin, 0.1 part of stabilizer; Component 2 includes the following parts by weight: 3 parts of dimethyl silicone oil, 95 parts of kerosene solvent, 1 part of 4-phenoxyphenylboronic acid, and 1 part of flame retardant. Component 1 and Component 2 are mixed and diluted in a weight ratio of 1:1.

[0054] The adhesive layer oil with self-healing characteristics was prepared as follows:

[0055] (1) heating petroleum pitch to 170~175 ℃, adding linear styrene-butadiene-styrene copolymer thereinto, and stirring for 60 minutes, and the stirring speed is 600 rev / min;

[0056] (2) in the above-mentioned mixture, add high density polyethylene, and shear and stir for 60 minutes, and the mixer rotating speed is 600 rev / min;

[0057] (3) adding stabilizer sulf...

Embodiment 2

[0061] Component 1 includes: 94 parts of petroleum asphalt, 2 parts of styrene-butadiene-styrene copolymer, 4 parts of polyolefin, and 0.1 part of stabilizer; Component 2 includes the following parts by weight: 3 parts of dimethyl silicone oil , 95 parts of kerosene solvent, 1 part of 4-phenoxybenzeneboronic acid, and 1 part of flame retardant. Component 1 and component 2 are mixed and diluted in a weight ratio of 1:1.5.

[0062] The preparation method of the adhesive layer oil with self-healing characteristics is the same as the preparation method in Example 1.

Embodiment 3

[0064] Component 1 includes: 93 parts of petroleum asphalt, 1 part of styrene-butadiene-styrene copolymer, 6 parts of polyolefin, and 0.1 part of stabilizer; Component 2 includes the following parts by weight: 2 parts of dimethyl silicone oil , 95 parts of kerosene solvent, 2 parts of 4-phenoxybenzeneboronic acid, and 1 part of flame retardant. Component 1 and Component 2 are mixed and diluted in a weight ratio of 1:1.

Abstract

The invention discloses a self-healing viscous layer oil and a preparation method. The raw materials are composed of two components. Component 1 includes 93-97 parts of petroleum asphalt, 1-2 parts of styrene-butadiene-styrene copolymer, 3-6 parts of polyolefin, and 0.1-0.2 parts of stabilizer; Component 2 includes 2 parts of dimethyl silicone oil -3 parts, 94-96 parts of kerosene solvent, 1-3 parts of 4-phenoxyphenylboronic acid, and 1-3 parts of flame retardant. The petroleum asphalt is heated, and styrene-butadiene-styrene copolymer and polyolefin are respectively added to it and stirred and sheared, then a stabilizer is added, and stirring is continued to develop and swell to obtain component 1; add two to the kerosene solvent. Methyl silicone oil, 4-phenoxybenzene boronic acid and flame retardant are stirred to obtain component 2, and component 1 and component 2 are mixed and diluted in a ratio of 1:1 to 1:1.5, and stirred, A viscous layer oil with self-healing characteristics is obtained. The invention has the characteristics of high-strength interlayer bonding performance, high self-healing property under normal temperature conditions, repeated bonding and strong environmental protection.

Description

technical field [0001] The invention relates to the technical field of road sticky oil, in particular to a sticky oil with self-healing characteristics and a preparation method. Background technique [0002] In recent years, my country's traffic has shown the trend of "high speed, large flow, heavy load and channelization", so it has put forward a severe test for the bonding layer between different structural layers. The bonding performance between road asphalt and aggregate is one of the decisive indicators to determine the resistance to loosening and spalling and the durability of asphalt pavement. Engineering experience shows that in areas with more friction with vehicle tires, such as parking areas at traffic light intersections on asphalt pavements, road surface diseases such as particle drop and looseness often occur. [0003] But the bonding ability of asphalt-aggregate is not one-time, under suitable temperature and pressure, the asphalt-aggregate in the state of mu...
