preparation example Construction
[0077] The present invention provides a kind of preparation method of epoxy asphalt material described in above-mentioned technical scheme, comprises the following steps:
[0078] a) Heat the asphalt to 80℃~180℃, mix epoxy diluent, epoxy compatibilizer, aliphatic dicarboxylic acid, aliphatic dicarboxylic polyanhydride and epoxy resin curing agent with the heated asphalt , to obtain part A of the epoxy asphalt material after stirring;
[0079] b) Mix part A and part B of the epoxy asphalt material obtained in step a) at room temperature to obtain an epoxy asphalt material, the part B is epoxy resin, and the part A and part B The mass ratio is (0.5~5):1.
[0080] In the present invention, the pitch is first heated to 80°C-180°C, preferably 90°C-170°C, more preferably 100°C-160°C, most preferably 110°C-150°C; Thinner, epoxy compatibilizer, aliphatic dicarboxylic acid, aliphatic dicarboxylic polyanhydride and epoxy resin curing agent are mixed with the heated asphalt, and after ...
Embodiment 1
[0090] 100 parts by weight of CH 3 (CH 2 ) 5 CH=CH(CH 2 ) 2 CH=CH(CH 2 ) 5 CH 3 And 150 parts by weight of epoxy resin (grade E-51, Sinopec Baling Petrochemical Co., Ltd.), and 7 parts by weight of catalyst ammonium bromide were added to the reactor, and reacted at 100 ° C for 4 hours , obtained with epoxy compatibilizer.
