Description
Technical Field
The invention relates to the technical field of coatings, in particular to an environment-friendly water-based permeable primer for repairing a paint film of a building steel structure.
Background
Steel structures are structures composed of steel materials and are one of the main building structure types. The steel structure mainly comprises steel beams, steel columns, steel trusses and other members made of section steel, steel plates and the like, and rust removing and preventing processes such as silanization, pure manganese phosphating, washing drying, galvanization and the like are adopted. The components or parts are typically joined by welds, bolts or rivets. Because of its light dead weight, and construction is simple and convenient, widely apply to fields such as large-scale factory building, venue, superelevation layer.
The steel structure belongs to metal materials, and metal can be easily corroded due to chemical or electrochemical action when contacting with surrounding media, and is a spontaneous and ubiquitous phenomenon. The metal corrosion brings much inconvenience to production and life, and causes huge economic loss.
There are many means for preventing corrosion of metals, such as using corrosion-resistant metal materials, electrochemical protection, adding corrosion inhibitors, coating anti-corrosive paints, etc. Among them, the use of anticorrosive coatings is most common. The variety of anticorrosive coatings is many, and the anticorrosive coatings mainly comprise: phenolic resins, epoxy resins, perchloroethylenes, polyurethanes, furan resins, rubbers, and the like, and are used in various corrosion-resistant applications as required.
At present, the common anticorrosion protective layer of the building steel structure is provided with the following components: the alkyd primer is matched with alkyd finish; the similar finish paint is matched with chlorinated rubber, high chlorinated polyethylene and chlorosulfonated polyethylene primer; the epoxy primer is matched with an epoxy micaceous iron intermediate paint, an epoxy finish paint or a polyurethane finish paint and the like; polyvinyl chloride red lead primer is matched with similar finish; the zinc-rich primer is matched with an epoxy micaceous iron intermediate paint, an epoxy finish paint or a polyurethane finish paint and the like; the metal covering layer sprayed with zinc, aluminum and the alloy thereof is matched with the closed bottom and the epoxy micaceous iron neutralization epoxy finish paint or polyurethane finish paint.
The anticorrosion coating can be gradually aged or generate defects under the influence of external natural environmental conditions, such as sun exposure, high and low temperature, water vapor, rainwater soaking and the like, so that a paint film is damaged. When air and moisture permeate into a paint film to contact a substrate, the protection effect of the paint film is ineffective, corrosion is accelerated, and finally the protection of the coating cannot reach the designed service life, so that the maintenance and repair of the anticorrosive paint coating are particularly important. According to the requirements of the regulations of the anticorrosion technical regulations of the building steel structure, the anticorrosion coating of the building steel structure needs to be maintained and managed regularly, including appearance inspection, anticorrosion performance inspection and corrosion amount detection, and the on-site repair of bulges, peeling and corrosion points is required, and the on-site repair needs to meet the following regulations:
1. the surface of the damaged part of the anti-corrosion protective layer is cleaned by adopting sand blasting for rust removal, and the rust removal grade of the surface of the anti-corrosion protective layer reaches Sa2 specified in the national standard GB 89231/2And (4) stages. When the sand blasting condition is not available, dynamic or manual derusting can be adopted, and the derusting grade reaches St3 grade.
2. The surface of the anti-corrosion protective layer at the lap joint part should be free of pollution and attachment and should have a certain surface roughness.
3. The repair coating is preferably an anticorrosive coating which is matched with the original coating or compatible with the original coating, and can meet the site construction environmental conditions, and the storage and the use of the repair coating meet the requirements of a product use specification.
And actually, when the steel structure is locally damaged after being used for a certain time and the original coating is matched to repair according to requirements, the steel structure can be repaired difficultly or cannot achieve the required repairing effect due to various reasons because of various problems, so that the service life of the steel structure is influenced, and the following points are summarized:
1) the positions of the building steel structure needing to be repaired in the using process are basically damaged in welding seams, assembly bolt contact points and transportation and assembly processes, and are not properly repaired at the moment, and the positions are mostly in a half-empty state after being installed or in steel structure assembly connection and some gaps. These locations requiring repair limit the inability of many pre-processing equipment to enter. Therefore, the pretreatment grade required by repair cannot meet the requirement in many times, and after the repair is carried out, the corrosion products, the residual moisture in gaps and the paint film after air repair, which are not treated in place on the substrate, continue to expand and corrode in a short time, and then the paint film is expanded to lose the protective effect.
2) After the assembly of part of indoor building steel structures is completed, fireproof paint can be coated, after the fireproof paint is coated on the steel structure anticorrosion paint film, the corrosion range is not easy to find due to the existence of the fireproof paint at the periphery of a corrosion point, only part of the corrosion point is easy to repair, the periphery corrosion still continues to spread, and then the paint film is lost to protect the effect.
3) The corrosion condition of the steel structure under natural environmental conditions is performed in the presence of air and water. Therefore, most of places of the building steel structure needing repairing still have moisture condensation, can seriously influence repairing coating, bring very big hidden danger.
Therefore, the repair paint with strong universality and low requirement on the substrate is of great research significance.

The performance test of the environment-friendly water-based penetration primer for repairing the paint film of the architectural steel structure obtained in the examples 1 to 6 and the comparative examples 1 to 3 is carried out, and the results are shown in tables 1 and 2.
Table 1 Performance test results of the environment-friendly water-based permeable primer for repairing paint film of building steel structure obtained in examples 1-5
Table 2 Performance test results of the environment-friendly water-based penetration primer for repairing paint film of building steel structure obtained in example 6 and comparative examples 1-3
As can be seen from tables 1 and 2: the environment-friendly water-based penetrating primer for repairing the paint film of the building steel structure has the following advantages: 1. the steel structure paint film with the color of the steel structure can be repaired in different colors under the condition of ensuring normal appearance, and the comparative example 1 shows that after the resin is replaced, the steel structure paint film with the color of the steel structure is unqualified due to the appearance of the steel structure with the color of the steel structure. The drying time was normal as determined by GB/T1728-. 2. Adhesion was tested according to GB/T9286-1998: the 1-grade adhesion is achieved when the rusty substrate is treated to st2 grade, and the 0-grade adhesion is achieved when the substrate is treated to st3 grade, which means that the paint can be fully penetrated and wrapped on the low-surface-treated substrate and can penetrate into the metal substrate for adhesion; the coating has 0-grade adhesive force with an epoxy coating, a polyurethane coating and a fireproof coating, which means that the coating can be well matched with an original steel structure design anticorrosive coating without incompatible phenomenon. As can be seen from comparative example 1, the adhesion failure phenomenon occurs on the treatment of the base material with different treatment grades and on the anticorrosive coating with different original design after the resin is replaced, which means that the conventional acrylic resin on the market can not meet the requirements on the performance. 3. The flexibility is detected according to GB/T1731-1993, and the impact resistance is normal according to GB/T1732-1993. 4. The water resistance can reach 240h according to GB/T1733 + 1993 detection, which represents that the paint has excellent water resistance, the paint film can well block water penetration, the phenomenon of unqualified water resistance is shown in a comparative example 1 when the conventional resin sold in the market is replaced, the phenomenon of reduced water resistance is also shown in a comparative example 2 when the amount of the main resin is reduced, which represents that the proportion of the resin has great influence on the water resistance, and the phenomenon that the proportion of the antirust pigment is replaced has little influence on the water resistance is shown in a comparative example 3. 5. The salt spray resistance detection is carried out according to GB/T1771-2007, the salt spray resistance level of 240h can be achieved in the treatment level 3 with rust, the treatment level 2 can be over 200h, and the paint has excellent anti-corrosion performance and can meet the repair anti-corrosion requirement. As can be seen from comparative example 1, the salt spray resistance of the replacement main body resin is greatly reduced on different substrate treatment levels, and the replacement main body resin is not qualified. It can be seen from comparative example 2 that reducing the resin ratio also greatly affects the salt spray resistance and further affects the effect, and it can be seen from comparative example 3 that reducing the amount of the anti-rust pigment also causes the salt spray performance to be greatly reduced, and further causes disqualification 6, and the acid and alkali resistance can meet the standard requirements when tested according to GB/T1763-79. 7. The total content of harmful elements in the coating is determined according to GB/T30647-2014, and the detection result shows that the coating does not contain heavy metals and is environment-friendly. 8. The test was carried out according to the specification of 5.3.6 in GB/T14449-2017 to satisfy the requirements for the ejection rate. 9. The internal pressure is tested according to the specification of 5.5.1 in GB/T14449-2017, and the requirements can be met. 10. The leakage test was performed as specified in QB 2549 and 2002 of 5.2, and was satisfactory.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
