Super temperature-difference resistant and salt-mist corrosion resistant asphalt varnish and preparation method thereof

Abstract

The invention discloses a super temperature-difference resistant and salt-mist corrosion resistant asphalt varnish prepared from the following raw materials in parts by weight: 20-24 parts of methyl organic silicon resin, 26-32 parts of vinyl resin, 4-6 parts of diaminodiphenyl-methane, 1-2 parts of benzotriazole, 4-5 parts of potassium polyacrylate, 3-5 parts of polyethylene glycol, 12-16 parts of modified asphalt, 7-9 parts of modified waste resin sand, 1-2 parts of sodium selenite, 0.5-1.0 part of an accelerant CMCM, 1-2 parts of cobalt naphthenate, 1-2 parts of triammonium citrate, 2-3 parts of aluminum stearate, 5-7 parts of polyacrylate, 1-2 parts of a silane coupling agent, 0.5-1.0 part of magnesium ammonium sulfate, 3-4 parts of floating beads, 2-3 parts of hollow microspheres, 6-9 parts of methylbenzene, 5-8 parts of dimethylbenzene and 6-9 parts of butanol acetate. By adopting the asphalt varnish disclosed by the invention, harms of the waste resin sand to the environment are solved, the production cost of the varnish is reduced, and the quality of the varnish is improved.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an asphalt paint with super temperature difference resistance and salt spray corrosion resistance and a preparation method thereof. Background technique [0002] The corrosive environment of the ocean is complex, which can be divided into the ocean atmosphere area (the part that does not touch seawater all the year round), the ocean splash area (the part where the splash of sea water can be sprayed), and the ocean tidal range area (the part that can be submerged by sea water when the sea tide rises) , the ocean full immersion area (the area soaked by seawater all the year round) and the seabed mud area (the part below the seawater full immersion area); the corrosion types are divided into uniform corrosion, pitting corrosion, crevice corrosion, turbulent corrosion, cavitation corrosion, galvanic corrosion, etc. Corrosion and corrosion fatigue, etc. Ships have been in t...

Problems solved by technology

The various organic resins or organic and inorganic compounds contained in a large amount of waste resin sand piled up are slow to decompose, causing serious harm to the soil, and can acidify the soil. Some compounds will flow into rivers with rain, polluting water sources, people Once consumed, it will cause serious damage to people's health
