Embodiment 1
[0044] Example 1: Add 57 parts (mass, the same below) of petroleum asphalt (origin: Shanjiasi) heated to 90-120°C into the reactor, add 1.14 parts of maleic anhydride, heat up to 120-155°C, and wait for the pressure to stabilize , into N 2 , keep the total pressure at 0.25MPa, and after 4 hours of reaction, slowly release the pressure to 0.1MPa. Then gradually lower the temperature to 100-110°C, add 10 parts of polyethylene glycol (DC-4110, Ningwu Chemical Plant, Jurong City, Jiangsu Province; calculated based on the neutralization of completely residual functionalized asphalt modified small molecular compounds parts by mass; the same below), 1.2 parts of liquid hydroxyl-terminated polysiloxane (107 silicone rubber, 3000 cP, Shanghai Silicon Mountain Polymer Material Co., Ltd.), and then the temperature was programmed to 130-140 ° C for 1-3 hours. Then add 17.16 parts of oxalic acid, 5 parts of polyisobutylene succinic anhydride (average molecular weight: 5100, Changzhou Guan...
Embodiment 2
[0045] Example 2: Add 57.3 parts of petroleum asphalt (US Shell) heated to 90-120 ° C into the reactor, add 11.4 parts of maleic anhydride, heat up to 120-160 ° C, and after the pressure is stable, feed N 2 , keep the total pressure at 0.45MPa, and after 5 hours of reaction, slowly release the pressure to 0.1MPa. Then gradually lower the temperature to 100-110° C., add 2 parts of polypropylene glycol (DC-403, Ningwu Chemical Factory, Jurong City, Jiangsu Province), and program the temperature to 130-140° C. to react for 1-3 hours. Then add 15.13 parts of dimer acid (Zhejiang Yongzai Chemical Factory), 10 parts of adipic acid, 3 parts of polyisobutylene succinic anhydride (average molecular weight 2400, Changzhou Guanghui High-tech Chemical Co., Ltd.) that have been heated to 90-140 ° C in advance, 10 parts of polyazelaic anhydride (average molecular weight 1200, Changzhou Guanghui High-tech Chemical Co., Ltd.) and 0.57 parts of triethylamine were pre-mixed for 30 minutes and d...
Embodiment 3
[0046] Example 3: Add 68 parts of petroleum asphalt (US Shell) heated to 90-140°C into the reactor, add 8.2 parts of maleic anhydride, heat up to 230°C for reaction, and reflux with 80°C warm water at the same time, after reacting for 6 hours, then gradually Cool down to 100-110°C, add 3.2 parts of liquid hydroxyl-terminated polysiloxane (107 silicone rubber, 3000cP, Shanghai Silicon Mountain Polymer Material Co., Ltd.), program temperature rise to 130-140°C and react for 1-3 hours. Alkyd resin (brand 3370A, Jiangsu Sanmu Group Co., Ltd.) 14.4 parts, methyl nadic anhydride (Changzhou Guanghui High-Tech Chemical Co., Ltd.) 5 parts, polyglutaric anhydride (average molecular weight 1200, Changzhou Guanghui High-Tech Chemical Co., Ltd.) ) 7 parts, and 0.6 parts of diethylenetriamine were added to the reactor, stirred and mixed for 1 hour, and finally dispersed at high speed in the colloid mill to obtain part A; when in use, part A and part B (epoxy resin E -44) Raise the temperatu...
