Emulsified asphalt is a road construction material that is usually used at high temperatures. It is dispersed into water through mechanical stirring and chemical stabilization (emulsification) to liquefy into a very low viscosity and good fluidity at room temperature. It can be used at room temperature and can also be used with cold and wet stones. Common emulsified asphalt can also be used as a waterproof coating;

[0003] In marine engineering, due to the high Cl - The concentration has a corrosive effect on building concrete and the steel bars in the concrete, seriously affecting their service life; therefore, the waterproof coating needs to be modified to give it better corrosion resistance; in addition, since asphalt is relatively viscous, during conventional production and processing, the range of the mixing blades is limited, and only laminar flow will be formed in the mixing area without forming eddy currents; therefore, dead zones are easily formed in places that cannot be mixed, resulting in waste of raw materials.

[0051] The dispersant is lime paste dispersant;

[0052] The filler is a slurry prepared by 70% of short asbestos fibers with a length of less than 6 mm, 20% of silicate powder, 1% of organic silicon defoaming agent, and the remaining components are water;

[0053] The mildew inhibitor is a suspension of zinc pyrithione containing not less than 60%;

[0054] Material B includes: 30% ammonium salt without chloride ions, 5% fluorinated polymer, 3% ethylene glycol, and the remaining components are deionized water; the above components are calculated by mass percentage;

[0055] Ammonium salts that do not contain chloride ions include ammonium sulfate or ammonium nitrate;

[0056] The fluorinated polymer includes one of polytetrafluoroethylene, polyvinylidene fluoride or perfluoroalkoxy resin to improve the anti-corrosion performance. Use the production device described in Example 2 to prepare material A and material B for use; adjust the pH value of material A to 10-13 with sodium hydroxide solution before use, which is conducive to the rapid solidification of the coating; then use different atomizing sprayers to spray material A and material B at the same construction surface at an angle of 45-60 degrees to form a conical surface; spray to form a waterproof layer in the construction area; after the atomizing sprayer discharges the material evenly, adjust the angle so that the two conical surfaces are staggered, and the staggered part is located 5-10 cm in front of the construction spraying area. In this embodiment, a cold asphalt suspension emulsion is made of asphalt as the base material, lime paste as the dispersant, and asbestos wool as the filler.
