AI Technical Summary

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

Abstract

Multifunctional liquid rubber spray coating comprises components of A, B, wherein A component comprises liquid rubber asphalt emulsion whose solid content is 50-75%, wherein 2-65% rubber elusion content, 30-97% asphalt elusion content, 0.0-5.0% carbon black, 0.0-6.0% ultra-fine powder, 0.025-2.50% anion dispersing agent and 0.025-3.00% anion surface activator, which is waterborne spray coating, and B component is water solution which comprises 3.0-18.0% concentration calcii chloridum (89.0-99.2%), sodium chloride (0.50-4.0%) and composite aluminum iron polymer (0.3-7.0%). The two components are sprayed on the same basal plane through adopting a double-component airless spraying device to form a gelatin film with 0.5-4mm after 3-5 seconds solidification, which has the characteristics of strong bonding, temperature resistance, weather resistance, and excellent chemical stability, heat insulation and puncture resistance. The A component can be individually sprayed, or can be combined with the double components.

Description

technical field [0001] The invention belongs to the field of spray coating compositions, and relates to a spray coating composition based on natural rubber, synthetic rubber and asphalt; and relates to a water-based latex coating composition. At the same time, it also relates to the process of coating liquid or other fluids with spraying system equipment and using methods on general surfaces. Background technique [0002] Coatings with multiple anti-corrosion functions, waterproof functions, protective functions, thermal insulation functions, sound absorption and noise reduction functions, and flame-retardant functions are very much needed materials for engineering construction in the construction industry. Especially in the protective construction of underground, road bridge, and tunnel engineering, it is necessary to coat the tunnel face with a layer of waterproof protective layer as soon as possible after excavation, and it is hoped that it will be cured soon.
