Abstract

The invention relates to the technical field of road surface deicing and particularly discloses biological anti-freezing protein water-based emulsion for preventing icy pavement as well as a preparation method thereof. The emulsion is prepared from the following raw materials in parts by mass: 3.2 to 12.8 parts of biological anti-freezing protein, 45 to 75 parts of water, 0.2 to 0.8 part of cationic emulsifier, 1 to 4 parts of butyronitrile rubber latex, 4 to 11 parts of calcium octadecate and 0.175 to 0.555 part of inorganic acid. According to the emulsion provided by the invention, the components are cheap, the production process is simple, the deicing effect is obvious, occurrence of icing is completely inhibited at -2 to 0 DEG C and the icing occurrence rate is 15 percent or below at -4 to -2 DEG C; furthermore, the size of ice crystals can be effectively reduced, and great popularization and application value is achieved in road icing regions in winter.

Description

technical field [0001] The invention relates to a biological antifreeze protein aqueous emulsion for preventing road icing and a preparation method thereof, belonging to the technical field of road deicing. Background technique [0002] At present, the means of deicing roads in winter is mainly to spread a certain amount of salt products, such as sodium chloride, on condensed road sections. The ice road section cannot be spread, resulting in a very unsatisfactory deicing effect. [0003] In order to solve the problem of road icing, many institutions and researchers at home and abroad have done a lot of research. In the past ten years, the more successful results are to imitate the biological superhydrophobicity of lotus leaves and use the surface wettability theory to prepare silane-based hydrophobic coatings. Spray on the road surface to form a super-hydrophobic anti-icing film, so as to carry out road anti-icing. The advantage of this method is that it is no longer passi...
