Description

Technical Field

[0001] The utility model relates to the technical field of road anti-icing mixture test equipment, and more specifically to a device for measuring the slow-release effect of an anti-icing mixture additive. Background Art

[0002] Anti-icing materials are mainly composed of hydrophobic materials and anti-icing components (inorganic halides or organic polyol compounds). They have a core-shell capsule structure at the microscopic level. The components that play an anti-icing role are wrapped by the external structure to reduce their release rate and increase the service life. Among them, the anti-icing component can lower the freezing point; the hydrophobic material mainly plays an interfacial isolation role, which can form an isolation interface on the surface of the road surface to block water infiltration and reduce the adhesion between ice and the road. In this case, the road surface will be difficult to freeze and the surface snow can be melted. Due to the anti-icing and hydrophobic properties of the anti-icing road surface, water will not freeze again on the road surface, and the ice and snow on the road surface can be easily removed.

[0003] On the basis of ensuring the lowering of the freezing point of the road surface, a slow-release agent is added to the anti-icing modifier. The main component of the slow-release agent is a microscopic porous material. After the effective components of the anti-icing modifier are coated, the effective components come into contact with the external environment through the pores of the porous material, which can reduce the loss of the self-melting ice modifier in the non-icing season, while ensuring the continuous precipitation of the effective components during snowfall and ice formation. However, different slow-release agent dosages will affect the effective service life of the anti-icing mixture specimens, and it is necessary to measure the anti-icing mixture specimens according to different asphalt mixture gradings. Therefore, it is necessary to design a corresponding measuring device to measure the slow-release effect of different dosages of slow-release agents. Utility Model Content
