Embodiment 1

[0029] Add 400g of naphthalene acid and 220g of triethylenetetramine into the three-necked flask, heat the mixture to 140°C in an oil bath, and stir the reaction for two hours. After two hours, connect the system to the vacuum system, start vacuuming, and pump the water in the three-necked flask After four hours, the water has been pumped out, and the liquid level in the three-necked flask is stable at this time, no more bubbles emerge, and the reaction is stopped to obtain naphthenic acid amide;

[0030] Add 206g of rosin and 100g of triethylenetetramine into another three-necked flask, heat the mixture to 140°C in an oil bath, stir and react for two hours, after two hours, connect the system to a vacuum system, start vacuuming, and drain the water Take it out, and after four hours, the water has been taken out, and now the liquid level in the three-necked flask is stable, no bubbles will emerge, and the reaction is stopped to obtain rosinamide;

[0031] Mix the prepared naph...

Embodiment 2

[0033] Add 400g of naphthalene acid and 220g of triethylenetetramine into the three-necked flask, heat the mixture to 140°C in an oil bath, and stir the reaction for two hours. After two hours, connect the system to the vacuum system and start vacuuming. The by-product water is pumped out. After vacuuming for two hours, raise the temperature of the oil bath to 180°C, and then continue to vacuumize. After reacting under vacuum for four hours, stop the reaction. At this time, the liquid level in the three-necked flask is stable and there are no more bubbles. , the oily liquid in the three-necked flask is imidazoline naphthenate;

[0034] Add 206g of rosin and 100g of triethylenetetramine into another three-necked flask, heat the mixture to 140°C in an oil bath, stir and react for two hours, after two hours, connect the system to the vacuum system, start vacuuming, and dehydration condensation reaction The by-product water is pumped out. After vacuuming for two hours, raise the...

Abstract

The invention relates to an asphalt material, particularly a preparation method of a rosin-base asphalt additive. The preparation method provided by the invention has the advantages of low price and low pollution. Naphthenate, rosin and polyethylene polyamine, which are used as raw materials, are successively subjected to amidation reaction, cyclization reaction and compounding to obtain the end product rosin-base asphalt additive. The invention has the advantages of small environmental pollution and the like, is convenient for construction and free from the restrictions of air temperature and weather conditions, can be supplemented when in use, and has wide industrial applicability.

Description

Technical field: [0001] The invention relates to an asphalt material, in particular to a preparation method of a rosin-based asphalt additive. Background technique: [0002] Asphalt cold patch is a high-tech road patching material. The key raw materials required for production are imported products. Its excellent bonding performance and loose construction performance are one of its notable characteristics different from ordinary patching materials. It can be used all-weather , suitable for repairing various types of road surfaces in any weather and environment, such as asphalt concrete roads, cement concrete roads, parking lots, airport runways, bridge expansion joints, etc. [0003] Asphalt cold repair technology is a new technology to repair road surface potholes without heating. The key process is to use high-tech means to produce a modified asphalt cold replenishment fluid, and then produce a cold patch asphalt mixture with a certain proportion and a certain gradation o...
