Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coatings, and particularly to an emulsified asphalt waterproof coating for marine engineering and a production device thereof. Background Art

[0002] Emulsified asphalt is a viscous asphalt that is dispersed in water containing an emulsifier - stabilizer in the form of micro - droplets through heat fusion and mechanical action, forming an oil - in - water (O / W) type asphalt emulsion. Emulsified asphalt is a road construction material that liquefies road asphalt, which is usually used at high temperatures, into a material with very low viscosity and good fluidity at normal temperature through mechanical stirring and chemical stabilization (emulsification) methods. It can be used at normal temperature or 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 - concentration in the marine environment, it has a corrosive effect on the concrete of buildings and the steel bars in the concrete, seriously affecting their service life; therefore, it is necessary to modify the waterproof coating to make it have better corrosion resistance; in addition, because asphalt is relatively viscous, in the conventional production and processing process, due to the limited range of the stirring blades, only laminar flow will occur in the stirring part and no eddy current will be formed; therefore, dead zones are easily formed in the places that cannot be stirred and cannot be mixed evenly, resulting in waste of raw materials.

Specific implementation mode

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Material A includes: 45% asphalt, 15% dispersant, 25% filler, 3% nano-silica, 2% sodium hydroxide aqueous solution, 0.1% mildew preventive, and the remaining components are water; the above components are all in mass percentage;

[0050] Among them, the asphalt is No. 60 petroleum asphalt;

[0051] The dispersant is lime paste dispersant;

[0052] The filler is a slurry prepared from 70% short asbestos fiber with a length of less than 6 mm, 20% silicate powder, 1% silicone defoamer, and the remaining components are water;

[0053] The mildew preventive is a zinc pyrithione suspension with a content of 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 all in mass percentage;

[0055] The ammonium salt without chloride ions includes ammonium sulfate or ammonium nitrate;

[0056] The fluorinated polymer includes one of polytetrafluoroethylene, polyvinylidene fluoride or perfluoroalkoxy resin to improve the anti-corrosion performance. The A material and the B material are respectively prepared using the production device described in Example 2 for standby; before use, the pH value of the A material is adjusted to 10 - 13 with sodium hydroxide solution, which is beneficial to the rapid solidification of the coating; then the A material and the B material are sprayed in a conical shape simultaneously onto the same construction surface at an angle of 45 - 60 degrees using different atomizing sprayers; a waterproof layer is sprayed in the construction area to be constructed; after the atomizing sprayers discharge materials evenly, the angle is adjusted to make the two conical surfaces staggered, and the staggered part is located 5 - 10 cm in front of the construction spraying area to be constructed. In this example, a cold asphalt suspension emulsion is processed with asphalt as the base material, lime paste as the dispersant, and asbestos wool as the filler. After spreading lime emulsified asphalt on the base layer, due to the evaporation of water, the internal structure of the suspension is redistributed, and the extremely fine asphalt particles, lime, and asbestos wool are squeezed and wrapped with each other. The asphalt coagulates into a film, and the lime forms a uniform honeycomb-like skeleton in the asphalt, thus becoming a waterproof layer with high heat resistance and good anti-aging performance; the function of rapid solidification is achieved by the ammonium salt without chloride ions in the B material, and at the same time, a mildew-proof agent and a fluorinated polymer are added to make it have better anti-corrosion performance.
