Embodiment 1

[0052] 1. The preparation method of oleyl chloride thermosetting epoxy asphalt compatibilizer, which includes the following steps:

[0053] 1) Preparation of oleyl chloride: In a 500 mL three-necked flask equipped with a constant temperature oil bath, a stirring device, and a reflux device, add 126 grams of oleic acid, 21 grams of phosphorus trichloride, and 140 grams of chloroform. The temperature is raised to 50°C for reaction 4. After hours, the lower layer precipitate was separated, and the solvent (trichloromethane) was evaporated to obtain 134 g of oleyl chloride.

[0054] 2) Add 40 grams of epoxy resin E-51 and 80 grams of acetone into a 250 mL three-necked flask, stir to fully dissolve the epoxy resin in the acetone, heat up to 35°C, and add 7 grams of 5wt% NaOH aqueous solution dropwise to complete the addition. Then, it was reacted at 35°C for 1.5 hours to obtain a hydrolyzed epoxy resin. Take 134 grams of oleoyl chloride and the hydrolyzed epoxy resin (40 grams) obtaine...

[0069] 2) Add 100 grams of epoxy resin E-44 and 200 grams of acetone into a 500 mL three-necked flask, stir to fully dissolve the epoxy resin in the acetone, raise the temperature to 35°C, dropwise add 20 grams of 5wt% NaOH aqueous solution, and add to complete Then, it was reacted at 35°C for 1.5 hours to obtain a hydrolyzed epoxy resin. Take 298 grams of oleyl chloride and the hydrolyzed epoxy resin obtained in this step, 300 grams of t...

Embodiment 3

[0073] 1. The preparation method of oleyl chloride thermosetting epoxy asphalt compatibilizer, which includes the following steps:

[0074] 1) Preparation of oleyl chloride: In a 500mL three-necked flask equipped with a constant temperature oil bath, a stirring device, and a reflux device, add 100 grams of undecylenic acid, 17 grams of dimethyl sulfoxide, and 120 grams of toluene, and heat to 60°C for reaction After 4 hours, the lower layer precipitate was separated, and the solvent (toluene) was evaporated to obtain oleyl chloride.

[0075] 2) Add 100 grams of epoxy resin E-42 and 380 grams of acetone into a 500 mL three-necked flask, stir to fully dissolve the epoxy resin in the acetone, raise the temperature to 35°C, dropwise add 20 grams of 8wt% NaOH aqueous solution, and add dropwise to complete Then, it was reacted at 35°C for 1.0 hour to obtain a hydrolyzed epoxy resin. Take 298 grams of oleoyl chloride and the hydrolyzed epoxy resin obtained in this step, 353 grams of tolu...

Abstract

The invention relates to a thermosetting epoxy asphalt material and a preparation method thereof, which are mainly used in field of buildings. The thermosetting epoxy asphalt material is characterized by being prepared from the following raw materials in part by weight: 100 parts of asphalt, 20 to 40 parts of epoxy resin, 20 to 40 parts of vulcanizer, 20 to 40 parts of curing agent, 0.3 to 1.2 parts of curing accelerator and 20 to 60 parts of oleoylchloride thermosetting epoxy asphalt compatibilizer. In the thermosetting epoxy asphalt material prepared by the method, the asphalt and the epoxy resin are uniformly mixed.

Description

Technical field [0001] The invention relates to a thermosetting epoxy asphalt material and a preparation method thereof, which are mainly used in the construction field. Background technique [0002] Asphalt has excellent water resistance, moisture resistance, and corrosion resistance, and is rich in resources and low in price. It has long been used as pavement materials and waterproof materials. However, due to the relatively low molecular weight of asphalt and its wide molecular weight distribution, it is highly sensitive to temperature. When the temperature is increased, the strength of the bitumen decreases; when the temperature is decreased, the bituminous material becomes brittle. Therefore, the wide application of asphalt is largely restricted. [0003] With the rapid development of highway construction in my country, the national trunk road network is being formed, with a large number of high-grade highways being paved and the construction of large-span bridges. This mak...
