Description
The technical field is as follows:
the invention relates to a method for manufacturing a high-performance solvent-free flame-retardant polyurea coating, belonging to the field of application of high-performance coatings.
Background art:
spray polyurea elastomer technology has undergone three stages of development, polyurethane, polyurethaneurea and polyurea. In the three systems, the component A is essentially identical, and is an aromatic or aliphatic prepolymer and a semi-prepolymer, with the difference being the component B. The component B of the spray polyurethane consists of hydroxyl-terminated resin and a hydroxyl-terminated chain extender, and contains a catalyst for improving the reaction activity.
The component B of the spray polyurethane/urea can be hydroxyl-terminated resin, or can be composed of amine-terminated resin and amine chain extender, and generally contains a catalyst for improving the reaction activity. The component B of the spray polyurea is required to be composed of an amino-terminated resin and an amino-terminated chain extender, does not contain any hydroxyl component and catalyst, and can contain a certain amount of a dispersing agent and neutral ash 2 BL.
Because the reaction activity of the amino-terminated compound and the isocyanate component is extremely high, the reaction can be instantly completed at room temperature or low temperature without any catalyst, thereby effectively overcoming the fatal defects that the polyurethane and polyurethane/urea elastomer are foamed due to the influence of environmental temperature and humidity in the construction process, and the material performance is rapidly reduced.
The polyurea spraying technology integrates the advantages of anticorrosive materials such as paint, rubber, plastic and the like, and is one of the most advanced international anticorrosive technologies at present. The gel has the technical advantages that the gel is fast cured, can be sprayed on any curved surface without generating a flow phenomenon, the gel time is as short as 10s or less, and the walking strength can be achieved within 10 min; it is not sensitive to temperature and moisture, and is not influenced by ambient temperature and humidity during construction. The polyurea can be constructed in a low-temperature environment of-28 ℃ and can also be constructed in a humid and rainy environment; the paint has 100 percent of solid content, meets the requirement of environmental protection, has no smell in the construction and use processes, and is particularly suitable for the anticorrosion construction of the inner wall of a storage tank and the inner wall of a pipeline with poor ventilation; the requirement of thickness can be met by one-time construction, and the defect that the traditional anticorrosive paint needs to be constructed for many times is overcome; the coating is compact and seamless, can resist the long-term corrosion of media such as water, seawater, acid, alkali, salt, oil and the like, and has outstanding resistance to chemical media and soil erosion; the mechanical strength is high, the elongation rate is good, the impact resistance is good, and the material is not easy to damage under the action of temperature alternation and external force impact; the adhesive force is good, the adhesive force is more than 10MPa on the steel which is sand blasted to Sa2.5 grade, and the steel does not fall off after long-term use; the breakdown voltage resistance is up to more than 20kv/mm, and the matching property with cathode protection is good; the catalyst is not contained, the ultraviolet light aging resistance is good, and the paint is not pulverized and cracked after being used outdoors for a long time; wide use temperature, can be used for a long time at the temperature of between 50 ℃ below zero and 121 ℃, and the modified high temperature resistant polyurea can be used for a long time below 150 ℃, and the like.
The polyurea spraying technology has excellent physical properties and construction performance, and is a novel coating technology. The material can completely or partially replace the traditional polyurethane, epoxy resin, glass fiber reinforced plastic, FBE and polyolefin compounds, and has wide application prospect in the industries of chemical corrosion prevention, pipelines, buildings, ships, water conservancy, traffic, machinery, mine wear resistance and the like.
The anticorrosive materials for the metal chemical storage tank are generally divided into two categories, namely a lining and a coating. Commonly used liners include rubber liners, plastic liners, and glass fiber reinforced plastic liners. The rubber lining is made of natural rubber or synthetic rubber and can be used at normal temperature and pressure. The disadvantages are that the field heating vulcanization is needed, the construction process is very complicated, and the quality is difficult to ensure. The plastic lining is generally a prefabricated block material, a special pasting process is needed during construction, and leakage is easily caused at a joint, so that integral failure is caused. The glass fiber reinforced plastic lining adopts a manual pasting process, has large smell, pollutes the environment, needs a plurality of constructions and is difficult to ensure the construction quality.
The traditional anticorrosive paint has the advantage of convenient construction, and can be used on the inner wall or the outer wall. However, these coating systems generally suffer from insufficient hardness and toughness, are highly susceptible to cracking under thermal stress or impact, premature cracking can lead to leakage of stored fluids, and repair and maintenance costs are increased; the system contains organic solvent, which is harmful to human body and pollutes environment, and pinholes generated by solvent volatilization can cause penetration of corrosive medium; multiple construction is needed, the period is long, the efficiency is low, and the like.
The polyurea spraying technology effectively solves the problems, has obvious technical advantages when being applied to corrosion prevention engineering of the inner wall and the outer wall of a steel storage tank, and has been successfully applied to projects such as crude oil tanks, heavy oil tanks, sewage tanks, hydrochloric acid tank cars and the like of Daqing oil fields, Shengli oil fields, Xinjiang oil fields, Qilu petrochemical industries, Lanzhou petrochemical industries and Yueyang petrochemical industries.
In addition, the SPUA technology can also be used for chemical storage tanks with heat preservation requirements as a protective layer of a heat preservation layer. The traditional method is to wrap galvanized iron sheets outside polyurethane foam, but the existing joints are easy to cause water inflow, and the foam is quickly corroded and aged. And the adoption of the SPUA technology can play the dual roles of corrosion resistance and water resistance, has no seam, and is beautiful and practical.
In order to prevent chemical raw materials from leaking, storage tank cofferdams are built around some chemical storage tanks. Early storage tank cofferdams are simple and crude, are generally formed by enclosing concrete or concrete walls, and are paved with broken stones at the bottoms. Once a large amount of raw materials are leaked, the cofferdam can be temporarily stored, but a small amount of leaked chemical raw materials can permeate into soil to cause serious pollution to the soil. With the increasing importance of the developed countries on environmental protection, the storage tank cofferdam must be completely closed to protect the soil. The plastic lining is applied to the storage tank cofferdam and has the advantage of good corrosion resistance, but the construction process is complex, and particularly the construction is very difficult in places with complex shapes and many pipe fittings. In addition, the constructed plastic lining has a large number of seams and often causes leakage, however, the polyurea can resist the erosion of water and most chemical media and has the characteristics of no pollution, no flowing, quick construction and the like. More importantly, the polyurea elastomer after spraying has no seams, good flexibility and elongation rate of more than 300 percent, can connect the capillary cracks on the concrete substrate together, and has excellent anti-seepage effect. At present, the application of polyurea in northern western Tai and Alaska areas in foreign concrete storage tank cofferdams in large quantities indicates that polyurea can withstand severe weather tests. Besides the storage tank cofferdam, the similar application fields also include the protection of surfaces such as chemical engineering trenches, power plant drainage ditches, ground impermeable layers and the like.
Polyurea represents the current development of the international latest anticorrosion technology. Currently, many of the international well-known pipe works use polyurea or/and polyurethane foam in combination for oil and gas pipelines that need to be insulated.
With the popularization and development of the polyurea technology, the superiority of the polyurea technology is well known by people. In the near future, polyurea will become one of the main corrosion-resistant materials for the outer wall of pipes together with fusion bonded epoxy powder, 3 PE.
The SPUA material can also be widely used as the inner wall anticorrosion of nodular cast iron pipes, steel pipes and cement pipes. To achieve a service life of 50 years, the inner wall of a cast iron pipe or a steel pipe must be subjected to an anticorrosive treatment, and a cement mortar lining has been conventionally used. The cement mortar is the pipeline lining with the longest history, but is easy to crack after stress shrinkage, and has more surface defects (such as pitted surfaces, sand holes and hollows); the cement mortar lining causes the content of soluble substances to be improved, the hardness to be changed, and NH3Precipitation, leading to alkalization of the water; the instability of water also affects disadvantages of cement mortar and the like.
When CO is in water2The mortar is damaged and sand grains are lost when the over-balance concentration reaches 7mg/L, so that the water quality is influenced. The SPUA material used as an anticorrosive material for the inner wall of the cast iron pipe has the advantages of good adhesive force, no cracking, strong corrosion resistance and long service life; the surface is smooth, the hydraulic friction coefficient is less than that of a concrete pipe and a steel pipe, and the water delivery efficiency can be improved. Under the condition of the same pipe diameter, the power and the energy of the pump are saved by more than 20 percent, and the operating cost is greatly reduced; no scale formation, no pollution of water quality by bacteria microorganism in water, no secondary pollution, and no change of permanent water delivery and water quality cleanliness.
In chinese patent No: 201110101576.3 discloses a method for producing a water-soluble polyurea resin, wherein the polyurea resin obtained by the method is mainly used for coating an article. A part of polyurea resin permeates into the object, so that the adhesion between the polyurea resin and the object is improved, and the polyurea resin is mainly used for fiber coating, concrete coating, water prevention and the like. In the application process of the water-soluble polyurea, the application field is limited.
In chinese patent No: 201110403185.7, which satisfies the requirements of not requiring long-term curing, not being affected by environmental conditions when cured, and not becoming yellow upon exposure to air for a long period of time, but in fact, the curing time of the polyurea resin composition is relatively long.
In chinese patent No: 201210198415.5, the modified polyurea coating is a polyurea resin synthesized by A, B two components, and 20-50 nm zinc oxide or titanium dioxide is blended as the inorganic modified filling material of the polyurea resin, however, in the process of the invention, the granularity of the zinc oxide and titanium dioxide is increased.
Chinese patent application No: 201310132859.3 discloses a spray polyurea coating and its preparation method; in the patent, two-component raw materials are adopted to prepare the polyurea coating, and because a certain amount of various additives are required to be properly added in the preparation process of the polyurea coating, the mass ratio of various components in the raw materials of the component B is changed after the additives are added, so that obvious formula difference exists for A, B two-component polyurea coatings.

The functional pigment is added into the resin system, so that certain properties of the coating can be effectively and pertinently improved, and the coating can be used in special environment, but the continuity of macromolecular segments is often influenced by the powder functional filler in the resin system, and the mechanical properties of the material are reduced to a certain extent. In addition, the dispersion of the powder particles in the resin often requires dilution with a large amount of solvent, which not only increases the production cost, but also causes great pollution to the environment. The invention has excellent dispersibility in a polyurea resin system without a solvent, and can construct good reflection performance and maintain good mechanical performance.

Meanwhile, the manufacturing method system of the high-performance solvent-free flame-retardant polyurea coating can show excellent mechanical performance, and can resist the phenomena of coating cracking, faults, peeling and the like caused by the change of an external environment in the using process to a certain extent. The method not only avoids the use of organic solvent, saves the production cost, but also does not damage the environment, more importantly solves the problem of extremely poor mechanical property of most of the prior coatings, prolongs the service life of the coatings and widens the application field of the coatings. The preparation method of the high-performance solvent-free flame-retardant polyurea coating provided by the invention has the advantages of high strength, excellent performance, low production cost, simple manufacturing process, no environmental pollution and easiness in realizing large-scale industrial production.
In the process of the invention, the purpose of adding the leveling agent properly is to facilitate the construction of the polyurea coating, which is beneficial to the flowing of the coating no matter manual or spraying, and certainly if the addition amount of the leveling agent is too much, the polyurea coating is easy to generate the phenomenon of bead hanging in the construction process of the building outer wall, on one hand, the construction quality is affected, and on the other hand, the polyurea coating is too wasted.
In the process of the present invention, the purpose of the appropriate addition of the defoamer is to eliminate the bubbles entrained by the polyurea coating composition during agitation to reduce the bubble content in the polyurea coating while improving the compactness of the polyurea coating.
