Problems solved by technology

[0003] At present, most of the spraying materials for industry or construction are paints or coatings, but the paints or coatings are not resistant to environmental aging. After rain, high temperature or sunlight, problems such as cracking, embrittlement, fading, and falling off will appear on the surface of the equipment or building. Cause equipment corrosion or building unsafe hidden danger
[0004] In addition, the existing spraying materials all contain solvents, which can cause diseases after being in contact with the human body or being inhaled. Even the anti-corrosion and environmentally friendly spraying paint formula disclosed in the patent application No. 201510692638.0 also contains alcohol solvents such as ethanol
[0005] Existing spraying material construction process is complex, as the patent application No. 201410088125.4 discloses a spraying paint formula and spraying process, even if it simplifies the traditional construction process, it also needs to spray three layers (primer, color paint, varnish ), and different steps also need to be baked, flowed, etc.; another example is that the patent application CN201410565667.6 discloses a method for spraying and repairing the sealant of the overall fuel tank of the aircraft, and the polysulfide sealant needs to be mixed with solvents such as acetone Uniform, and mixed with the grinding additives, until the viscosity is suitable for spraying

Abstract

The invention provides a spraying type silicone sealant. The spraying type silicone sealant is prepared from the following components: hydroxyl-terminated polydimethylsiloxane with the viscosity of 100cp to 10000cp. The spraying type silicone sealant can be directly sprayed on the outer surface of equipment or a building, an elastic sealing film can be formed after curing, air and moisture are isolated, and therefore corrosion of the equipment and the building is effectively prevented. The spraying type silicone sealant does not contain any solvent, is harmless to a human body and does not pollute the environment.
