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. 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 have a great impact on the body of the constructor and the environment.

preparation example Construction

[0046] The present invention provides a kind of preparation method of a kind of cold mix epoxy asphalt material described in above-mentioned technical scheme, comprises the following steps:

[0047] a) Add asphalt, asphalt diluent, epoxy asphalt compatibilizer, and epoxy asphalt curing agent into a common reaction kettle and mix to obtain part A of epoxy asphalt material;

[0048] b) Add epoxy resin and epoxy diluent together into an ordinary reaction kettle and stir and mix to obtain part B of epoxy asphalt material;

[0049] c) Mix part A of the epoxy asphalt material obtained in step a) with part B of the epoxy asphalt material obtained in step b) to obtain an epoxy asphalt material, the weight ratio of the part A to the part B For (0.5~5): 1;

[0050] The step a) and the step b) are in no sequence.

[0051] According to the present invention, the parts A and B are the same as those described above, and will not be repeated here.

[0052] In the present invention, some s...

Abstract

The invention provides a cold mixing epoxy asphalt material and a preparation method. The cold mixing epoxy asphalt material comprises a part A and a part B; the part A comprises the following components by weight: 100 parts of asphalt, 5-50 parts of epoxy asphalt diluents, 10-50 parts of epoxy asphalt compatibilizer and 5-50 parts of epoxy asphalt curing agent; the part B comprises the following components by weight: 40-100 parts of epoxy resin and 5-50 parts of epoxy resin diluents, wherein the weight ratio of the part A to part B is 0.5-5: 1. In the invention, the asphalt diluent and the epoxy diluent provide better construction fluidity to the epoxy asphalt material under room temperature, and easily penetrate into the pavement cracks for repairing; and can be stirred under normal temperature for usage without heating and insulation transportation.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cold-mix epoxy asphalt material capable of stirring, mixing and construction at room temperature and a preparation method thereof. Background technique [0002] The epoxy asphalt material disclosed in the prior art is a semi-fluid paste at room temperature. When paving and using, it must be heated under strict high temperature control to make its viscosity reach about 200cp, such as the mixing temperature of ChemCo epoxy asphalt in the United States. The mixing temperature of TAF epoxy asphalt in Japan is 121°C, and the mixing temperature is 180°C. 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. Transportation is difficult. On the other hand, during the heating process of epoxy asphalt, asphalt fumes harmful to human body will be produced, which w...
