Problems solved by technology

Moreover, the epoxy asphalt aggregate that has been mixed must be transported from the mixing station to the construction site under the condition of heat preservation. On the one hand, the production energy consumption of epoxy asphalt is high due to external heating. Transportation is difficult. On the other hand, during the heating process of epoxy asphalt, asphalt fumes harmful to human body will be produced, which will cause great damage to the body of the constructor and the environment.

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.

Abstract

The invention provides an epoxy asphalt material comprising a part A and a part B, wherein the part A comprises the following components in parts by weight: 100 parts of asphalt, 5-50 parts of epoxy diluent, 10-50 parts of epoxy compatibilizer, 10-50 parts of aliphatic dicarboxylic acid, 10-50 parts of aliphatic dicarboxylic acid polyanhydride and 5-50 parts of epoxy resin curing agent; the part B is epoxy resin; and the mass ratio of the part A to the part B is (0.5-5):1. In the invention, the epoxy diluent enables the obtained epoxy asphalt material to have good construction mobility at room temperature so that the epoxy asphalt material does not need to be heated for use and preserved with heat for transportation; and the epoxy asphalt material can be blended with stone at the room temperature for use, and has long operable time. Experimental results indicate that the epoxy asphalt material provided by the invention has a viscosity of about 200 cp at 20 DEG C and the time for the viscosity to reach 1000 cp is 84 minutes.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an epoxy asphalt material and a preparation method thereof. Background technique [0002] Epoxy asphalt is developed on the basis of ordinary asphalt. It has excellent high temperature stability, low temperature crack resistance, super fatigue resistance and excellent durability. The Marshall stability of the mixture obtained with stone can be More than 40KN, while the stability of ordinary asphalt concrete is only 8KN ~ 12KN, the difference is 4 to 5 times; the splitting strength can reach 4MPa, which is much higher than ordinary asphalt mixture, and the fatigue life is almost 10 times that of ordinary asphalt concrete ~ 30 times. Based on the excellent performance of epoxy asphalt, it is widely used in steel bridge deck pavement, tunnel pavement pavement, airport runway pavement, wharf and other heavy-duty traffic pavement pavement. [0003] The first application o...
