Problems solved by technology

[0003] At present, in asphalt mixture transportation and asphalt pavement construction, rubber-tyred road rollers and transport carriage boards generally use diesel oil, vegetable oil, etc. as release agents. On the road performance of asphalt pavement will have a greater negative impact
In particular, the effect of the oil-based release agent on the dilution of the asphalt on the road surface causes the asphalt film on the road surface to peel off easily, and the aggregate on the road surface is easily exposed for a short time, thus accelerating the early water damage of the asphalt pavement; for steel wheel rollers, watering is generally used The method is to prevent the wheel from sticking, and a large amount of water is used to reduce the surface temperature of the mixture quickly, especially during low temperature construction, which seriously affects the compaction of the asphalt mixture, thereby affecting the road performance

Abstract

The invention discloses a water-soluble environment-friendly asphalt separant and a preparation process thereof. The water-soluble environment-friendly asphalt separant is prepared from the following raw materials in parts by weight: 8 to 10 parts of kelp extract, 0.2 to 0.5 part of polyethylene glycol, 4 to 6 parts of peregal, 1 to 3 parts of sodium nitrilotriacetate, 0.1 to 0.3 part of gelatin, 2 to 5 parts of modified silicone oil, 2 to 3 parts of emulsifier and 20 to 35 parts of water. The preparation method comprises the following steps: preheating a kelp extract, sodium nitrilotriacetate, gelatin, modified silicone oil and polyethylene glycol, sequentially adding into a reaction kettle, stirring for 15 minutes, adding peregal and water, continuously stirring for 15 minutes, adding an emulsifier, and carrying out high-speed shearing emulsification for 3 times through colloid, so as to prepare the water-soluble environment-friendly asphalt separant. The modified silicone oil has excellent water solubility, so that the separant can be washed away by water in time after being used for the pavement without causing early water damage to the asphalt pavement; and furthermore, the problem that the current separant has a remarkable dissolving effect on asphalt in an asphalt mixture is solved.

Description

Technical field[0001]The present invention belongs to the technical field of road materials, and is specifically a water-soluble environmentally-friendly asphalt isolation and its preparation process.Background technique[0002]Isolating agent is a functional material between the mold and the sample, a type of processing auxiliary agent to prevent sample and mold bonding on the surface of the surface of the object to be easily bonded to each other. The isolation agent is used as a material applied to the surface of the mold, which can form a micrometer thickness and thermally stable film layer in the mold surface, which can make the molded specimen easily detach, and the ingredients of the isolator Less affected.[0003]At present, asphalt mixture transportation and asphalt road construction, glue roller and transport vehicle boards generally use diesel, vegetable oil, etc., such isolators have significant dissolved effect on asphalt in asphalt mix, residual road surface On, the road pe...
