Preferably, the spraying thickness in the material A priming process is 0.2 mm; meanwhile, the spraying thickness in the process of spraying A, B materials is 1.5-2.0 mm.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, a zinc oxide cross-linking agent, sodium silicate and a mildew-proof bacteriostatic agent are added into the material A of the system, and the material B selects a soluble metal salt without chloride ions as a coagulant, so that the marine corrosion-resistant chloride ion penetration-resistant bacteriostatic spray-quick-setting rubber asphalt waterproof coating is prepared. Wherein, the soluble metal salt without chloride ion is used as a physical coagulant to quickly coagulate the rubber asphalt mixed emulsion into a film, so that the construction is quick and convenient without sagging; the zinc oxide is used as a chemical cross-linking agent to be cross-linked with the neoprene latex component, so that the chemical cross-linking points of the coating are increased, the compactness of the coating is improved, and the chloride ion permeability, the waterproof performance and the mechanical performance are improved; the sodium silicate component is used as a base surface improving treating agent, after the material A is primed, the sodium silicate component, the rubber asphalt and other components can simultaneously permeate into concrete pores, the sodium silicate can react with cement to block pores, and the rubber asphalt component and a quick-setting film sprayed immediately next ensure good interlayer bonding; the bacteriostatic agent realizes bacteriostatic action.

In the prior art, the CN107043598A adopts polyisocyanate to crosslink with rubber components, and the nano zinc oxide has the activation effect. The polyisocyanate is crosslinked with organic ammonium, acid and alcohol in the component C besides the rubber component, and the quick-setting essence is that the polyisocyanate is crosslinked with the organic ammonium, acid and alcohol in the component C.

In addition, the material B is compounded by selecting the alkyl polyoxyethylene ether and the soluble salt without chloride ions, the addition of the alkyl polyoxyethylene ether reduces the rapid hardening speed to a certain extent, and is not easy to observe in a test rapid hardening time experiment because both are instantaneous rapid hardening, but can be seen from the time of coating water outlet after spraying, the time of forming small water beads by the spraying film without the alkyl polyoxyethylene ether is about 10-15 s, the water outlet time of the spraying film with the added alkyl polyoxyethylene ether is prolonged to 25-30 s, the water outlet speed is reduced, and the water outlet period is prolonged; although the water outlet is slow, the construction is not influenced, the sagging problem is not generated, the boiling point of the glycol added in the material B is higher than 197.3 ℃, the glycol has a certain evaporation rate, but is slower than water, and the drying speed is reduced; the alkyl polyoxyethylene ether and the ethylene glycol act together, and the problems of foaming, cracking and the like of a coating film caused by too fast drying of the coating film are solved.
