AI Technical Summary

Problems solved by technology

At present, the main types of anti-stripping agents are: (1) Inorganic, such as lime, with low cost and good performance, but the process is relatively complicated, and if the process is not proper, the durability will be affected; (2) Metal saponified products, such as saponin iron, Low cost and easy to use, but due to the large difference in density with asphalt, it is easy to produce segregation and affect the effect
(3) Quaternary ammonium salt, easy to use, but poor performance due to poor stability
(4) Polymers, such as polyamide polymers, have good performance and are easy to use, but the cost of raw materials is relatively high

Embodiment Construction

[0011] Specific examples will be given below to better illustrate the effects of the present invention. The weight percentages of the specific components are: 50% polyethylene glycol 400, 15% diethylamine, 15% hexamethylenetetramine, 18% diethanolamine, and 2% ethylene glycol ether. First mix polyethylene glycol with hexamethylenetetramine and diethylamine, stir well, then add diethanolamine and glycol ethyl ether, then add to the hot melt pitch, stir well, let stand for one day before doing Adhesion test.

[0012] The asphalt anti-stripping agent prepared above was added to Esso asphalt, and the adhesion performance test test was carried out by boiling method. The asphalt anti-stripping agent prepared above was added to the asphalt at a rate of 0.4% of the asphalt mass fraction, according to national standards. The test was carried out by the boiling method, and compared with the commercial anti-stripping agent and the adhesion performance of the matrix asphalt. The performance...

Abstract

The invention relates to an asphalt antistripping agent of asphalt for a pavement and a preparation method thereof. The asphalt antistripping agent is prepared from the following raw materials in parts by weight: 50-65 parts of polyethylene glycol, 10-30 parts of alkoxy aliphatic polyamines, 5-15 parts of alkylamines, 5-15 parts of polyamines, 1-2 parts of alcohol ether compounds and 13-29 parts of diethanolamine. The preparation method comprises the following specific steps: mixing and dissolving the components in proportion and mixing the mixture with the asphalt. The new asphalt antistripping agent has the advantages of good antistripping effect and good thermal stability and cost performance.

Description

Technical field: [0001] The invention belongs to the field of chemical industry, and relates to an asphalt additive and a preparation method, in particular to a road asphalt anti-stripping agent and a preparation method thereof. Background technique: [0002] Due to the advantages that are difficult to replace, such as comfortable driving, fast traffic speed, high flatness, easy construction, and convenient maintenance of asphalt pavement, the traffic mileage of asphalt pavement is increasing year by year. Especially in recent years, with the development of asphalt pavement technology, the paving mileage of asphalt pavement has increased sharply. [0003] However, there are various types of diseases on asphalt pavements in various countries, and water damage is one of the most common types of diseases on asphalt pavements. It is mainly manifested by the peeling of asphalt from the surface of the aggregate, the loss of the cohesive force of the mixture, the decrease of the strength...
