Abstract

The invention discloses a water-soluble boiled tung oil environment-friendly asphalt separant, which is prepared from the following raw materials in parts by weight: 3 to 5 parts of boiled tung oil, 8 to 10 parts of kelp extract, 0.2 to 0.5 part of polyethylene glycol 200, 4 to 6 parts of peregal, 1 to 3 parts of sodium nitrilotriacetate, 0.1 to 0.3 part of gelatin and 8 to 10 parts of deionized water. The preparation method comprises the following steps: S1, preparing a compound stabilizer; s2, preparing a compound emulsifier; s3, sequentially adding a compound emulsifier and a compound stabilizer into boiled tung oil, stirring, adjusting the pH value to be neutral, and then adding the mixture into quick stirring and emulsifying equipment for emulsification and stirring; and S4, after stirring, taking out the emulsion in the charging barrel to obtain the water-soluble boiled tung oil environment-friendly asphalt separant. The problems that in the prior art, an asphalt separant is high in cost, unsafe to use and not environmentally friendly are solved.

Description

technical field [0001] The invention belongs to the technical field of asphalt release agents, in particular to a water-soluble cooked tung oil environment-friendly asphalt release agent. Background technique [0002] In the asphalt pavement construction of the highway, since the asphalt mixture (mixed with asphalt and mineral materials at high temperature) must be paved at a high temperature of 110-130 ° C, the paving contact parts of the paving equipment The surface of the surface, the surface of the direct contact part of the rolling equipment, transportation means, auxiliary small tools, etc., because the surface temperature of the contact part is low, the asphalt mixture begins to cool and solidify with the temperature change, and thus adheres to the surface of the contact part of the equipment, etc. Over time, more solidified asphalt mixture will accumulate on the equipment. On the one hand, it will affect the subsequent construction operations of equipment and tools. ...
