Slow-release salt-melting material for road surface thin ice, ice- inhibiting fog sealing layer material and application

The invention discloses a slow-release salt-melting material for road surface thin ice and an ice-inhibiting fog sealing layer material. An ice-melting salt is dissolved into high-temperature water atthe maximum concentration to prepare a saturated solution of the ice-melting salt, diatomite powder is added to adsorb and store ice-melting salt ions to obtain an adsorption salt, the adsorption salt is dried and crushed to obtain the slow-release salt-melting material, and the slow-release salt-melting material is mixed with slow-breaking emulsified asphalt to obtain the ice-inhibiting fog sealing layer material. The diatomite salt storage material in the ice-inhibiting fog sealing layer absorbs water when being wetted and escapes along with salt, and the demulsification curing time is shorter than that of a pure emulsified asphalt fog sealing layer, so that rapid opening of traffic is facilitated; meanwhile, the diatomite can adsorb the asphalt droplets, a large amount of structural asphalt with a high strengt
