Description
Technical Field
The invention belongs to the field of water-based paint, and particularly relates to efficient anticorrosive flame-retardant epoxy graphene paint and a preparation method thereof.
Background
The development of the construction industry is promoted by the development of economy and society, and large buildings such as exhibition halls, terminal buildings, superstores, gymnasiums, high-grade hotels, industrial plants and the like are continuously increased and develop towards large and attractive directions, and most of main bearing and reconstruction pieces of the large buildings are steel structures. As a new building structure form in recent years, a steel structure has the characteristics of flexible structure, light dead weight, high strength, good shock resistance and deformation, short construction period, easiness in maintenance and the like, is widely applied to buildings, and particularly shows strong vitality in the aspects of super high-rise and large-span buildings and the like. For this reason, fire protection of steel structures is receiving increasing attention. Although steel is a non-combustible material, its fire resistance is far inferior to that of masonry and reinforced concrete structures, and the mechanical strength of steel decreases with the increase of temperature. When the temperature is raised to the critical temperature of the steel (generally 540 ℃), the yield stress is only 40% of the normal temperature. The fire resistance limit of the steel is only 15min under the direct burning of high-temperature flame. The fireproof coating is an ideal method for preventing the fire of the steel structure building. The steel structure is used as the main form of modern buildings, and is widely applied due to the advantages of light weight, high strength, good earthquake resistance, short construction period, high building industrialization degree, high space utilization rate and investment saving. The metal corrosion brings huge economic loss, wherein 30% of steel is wasted due to corrosion, the steel structure must be coated with anticorrosive paint, and the steel structure fireproof paint is a necessary material for steel structure enforced by the state. The paint is a material which can be coated on the surface of an object by different construction processes to form a continuous solid film with firm adhesion and certain strength, and the film formed by the method is generally called a coating film, also called a paint film or a coating. The object is exposed in the atmosphere and is corroded by oxygen, moisture and the like, so that the damage phenomena such as metal corrosion, wood decay, cement weathering and the like are easily caused, the surface of the object is coated with the coating to form a protective film, the occurrence and the development of the damage phenomena can be prevented or delayed, and the service life of various materials can be prolonged.
With the rapid development of infrastructure construction, particularly the building industry, in our country, steel structure building materials are increasingly used in industrial, commercial and civil buildings; meanwhile, in the industries of chemical industry, petroleum, food, light industry and the like, most of equipment and pipelines also need to be protected against fire. Whether steel structure buildings, chemical equipment and pipelines are subjected to anti-embroidery and anti-corrosion protection before fireproof coating. The fire-proof paint is also called fire-retardant paint, and has the functions of preventing flame from spreading rapidly or forming a heat-insulating layer to isolate the substrate from the heat source in case of fire by changing the surface combustion characteristics of the material. The anticorrosive paint forms a compact protective layer on the surface of the material, so that the material is prevented from being oxidized, decomposed and the like, and the service life of the material is prolonged. However, the current common practice is: the surface of the steel structure is coated with a layer of rust-proof and corrosion-proof primer, and then a layer of fireproof paint is coated on the primer. This approach has two major drawbacks: (1) the antirust and anticorrosive coating is usually red lead alkyd resin or zinc-rich epoxy resin, which causes serious pollution to the environment; (2) the bonding force between the antirust anticorrosion coating and the fireproof coating is different to a certain extent, the compatibility is poor, after long-term use, two layers of coatings of the material can be stripped and fall off, and further the protection of the base material is lost, so that the service life of the material is shortened. Therefore, the development of the steel structure fireproof coating with the advantages of good fireproof performance, excellent corrosion resistance, weather resistance, aging resistance, good decoration and the like is undoubtedly an important task for the research of the steel structure fireproof protection technology in China.
