Abstract

The invention relates to a bulking agent and a preparation method thereof. The preparation method of the modified epoxy resin thermosetting epoxy asphalt bulking agent is characterized by comprising the following steps of: selecting 80 parts of epoxy resin, 187 parts of trichloromethane, 100 parts of oleic acid and 0.01-0.1 part of stannic chloride by weight; dissolving the epoxy resin into the trichloromethane; adding the oleic acid; and dripping the stannic chloride at 40 DEG C-45 DEG C to react for 1-1.5 hours to obtain the modified epoxy resin thermosetting epoxy asphalt bulking agent. The bulking agent obtained in the method can ensure that the asphalt and the epoxy resin are mixed more uniformly.

Description

technical field [0001] The invention relates to a compatibilizer and a preparation method thereof. The compatibilizer is mainly used in the preparation of thermosetting epoxy asphalt materials in the construction field. Background technique [0002] Asphalt has excellent water resistance, moisture resistance, and corrosion resistance, and its resources are abundant and its price is low. It has been used for pavement materials and waterproof materials for a long time. However, due to the relatively low molecular weight of asphalt and its wide molecular weight distribution, it is highly sensitive to temperature. As the temperature increases, the strength of asphalt decreases; as the temperature decreases, the asphalt material becomes brittle. Therefore, the wide application of asphalt is largely limited. [0003] With the rapid development of highway construction in our country, the national trunk highway network is being formed, a large number of high-grade highways are pav...
