Problems solved by technology

However, there are several major defects in its technical realization: one is that 65%-75% of the asphalt emulsion containing 65%-98% is solid matter; the rubber emulsion containing 2%-35% contains 55%-65% of solid matter , this raw material is difficult to purchase with
Second, the spray gun system design is extremely complex
The technology provided by US4287242 is: add anionic surfactant in the rubber asphalt emulsion, use airless spray equipment, make the emulsion and multivalent metal salt solution continuously contact and mix at the position between the spray equipment and the base surface to be sprayed, Therefore, a solid coating of rubber asphalt is formed on the surface of the foundation, and characteristics such as waterproof, moisture-proof and gas-proof are rapidly formed on the surface of the foundation; however, an anionic emulsion of rubber asphalt containing 70-80% of solid matter is also required, and this raw material is not easy to obtain
