Description
Technical Field
The invention belongs to the technical field of waterproof and anticorrosive coatings for buildings, and particularly relates to a polymer asphalt glass flake waterproof and anticorrosive coating.
Background
The heavy-duty anticorrosive coating is one of paint coatings, and can be used in a relatively harsh corrosive environment and can achieve a longer protection period than a conventional anticorrosive coating. The glass flake coating belongs to an effective heavy anti-corrosion coating, the glass flakes are flake thin glass products with the thickness of 3-4 mu m, and because the glass flakes are very thin, the glass flakes are mutually parallel and overlapped in the coating film to generate a labyrinth effect, so that a unique shielding structure is formed, and fluid or gas generates resistance through the flake layered structure and reduces the flow, thereby increasing the anti-permeability and mechanical strength of the coating film and achieving the purpose of prolonging the anti-corrosion time of a matrix.
The currently used glass flake anticorrosive coatings are mostly epoxy glass flake anticorrosive coatings, have the problems of poor ultraviolet resistance, low elongation and the like, and can not meet the use requirements when being applied to the field of building water resistance and corrosion resistance.
Disclosure of Invention
The invention provides a polymer asphalt glass flake waterproof anticorrosive coating which is researched and developed aiming at the problems of poor ultraviolet resistance, low elongation and the like of epoxy glass flake anticorrosive coatings and is applied to the field of building waterproof anticorrosion.
In order to achieve the purpose, the invention adopts the following technical scheme:
the polymer asphalt glass flake waterproof anticorrosive paint comprises the following components in parts by weight: 20-30 parts of emulsified asphalt, 20-30 parts of glass flakes, 15-20 parts of acrylic emulsion, 15-20 parts of heavy calcium carbonate, 2-5 parts of barium sulfate, 5-8 parts of water, and a proper amount of dispersant, defoamer and preservative.
Further, the polymer asphalt glass flake waterproof and anticorrosive paint comprises the following components in parts by weight: 30 parts of emulsified asphalt, 20 parts of glass flakes, 20 parts of acrylic emulsion, 20 parts of heavy calcium carbonate, 5 parts of barium sulfate, 5 parts of water, a dispersing agent, a defoaming agent and a proper amount of a preservative.
Further, the polymer asphalt glass flake waterproof anticorrosive paint is characterized in that the defoaming agent is nonylphenol polyoxyethylene ether, the dispersing agent is sodium hexametaphosphate, and the preservative is isothiazolinone.
Further, the polymer asphalt glass flake waterproof and anticorrosive coating comprises the following components in parts by weight: 0.3 part of nonylphenol polyoxyethylene ether, 0.6 part of sodium hexametaphosphate and 0.4 part of isothiazolinone.
Further, the polymer asphalt glass flake waterproof and anticorrosive paint has the emulsified asphalt mixing temperature of 40-80 ℃.
Further, the preparation method of the polymer asphalt glass flake waterproof and anticorrosive paint comprises the following steps: firstly, adding emulsified asphalt, glass flakes, acrylic emulsion, heavy calcium carbonate, barium sulfate and water into a paint mixing tank according to a proportion, stirring and dispersing for 4-5 minutes at 400 revolutions per minute of 300-.
The petroleum asphalt has the characteristics of excellent cohesiveness, good aging resistance, high impedance value, low corrosion current density and the like, and the raw materials are easy to obtain and low in price, and the petroleum asphalt is taken as the raw material of the anticorrosive paint and occupies a leading position in the anticorrosive field for a long time. However, the coating has the characteristics of hot flowing and cold brittleness, so that the coating is always prepared into a solvent type anticorrosive coating, the problems of pollution and high cost caused by an organic solvent are solved by using water as a solvent through an asphalt emulsification technology, the problems of environmental pollution, resource waste and harm to human bodies caused by solvent volatilization during production and use are solved by using water as a solvent through the asphalt emulsification technology, and meanwhile, the material cost is greatly reduced. The emulsified asphalt is oil-in-water or water-in-oil liquid asphalt produced by asphalt and emulsifier under the action of certain process, and has very low viscosity and good fluidity at normal temperature. Because of its good adhesion, aging resistance and water-proofing ability, it has been widely used for a long time for water-proofing and sealing materials, road repairs and the like. As a traditional waterproof material, asphalt still has a huge application market. According to the difference of the electric property of the used emulsifier, the emulsified asphalt is divided into cationic emulsified asphalt, anionic emulsified asphalt, nonionic emulsified asphalt and the like.
The glass flake is a flake-shaped thin glass product with the thickness of 3-4 mu m, the glass flake is used as an anticorrosive coating of a filler, the anticorrosive coating has high cohesive force and excellent chemical resistance and ageing resistance, flat glass flakes with the transverse-longitudinal ratio of 30-120 in the constructed glass flake coating are of a palace structure which is arranged in parallel in an overlapping mode in resin, so that a compact impermeable layer structure is formed, and permeation of corrosive media in the solidified resin must pass through numerous tortuous paths, so that in an anticorrosive layer with a certain thickness, the distance of corrosion permeation is greatly prolonged, and the thickness of the anticorrosive layer of the glass flake is effectively increased.
The acrylic emulsion has excellent gloss and transparency, good anti-blocking performance, good cohesiveness, aging resistance and corrosion resistance of asphalt, and good tensile strength, elongation at break, low-temperature flexibility and bonding strength to a base material when being compounded and crosslinked with the water-based acrylic emulsion.
The invention has the advantages and beneficial effects that: the invention mainly comprises polymer emulsion, emulsified asphalt, glass flakes, heavy calcium and other fillers, takes the acrylate elastic emulsion and the emulsified asphalt as film forming substances, has good emulsifying effect, effectively solves the problem of ultraviolet resistance of the building waterproof anticorrosive coating by compounding the emulsified asphalt, the acrylic emulsion and the glass flakes, further strengthens the physical properties of the coating by adding the heavy calcium and the barium sulfate, and is green and environment-friendly.
