Problems solved by technology

The coating can form a uniform, hydrophobic, elastic and non-porous surface, with a total thickness of 200μm-300μm. The thermal conductivity of the high-temperature epoxy modified urushiolphthalein anti-corrosion coating is 2.134w / m??k, and the coating thickness is thin , so the effect on the heat transfer coefficient is very small. Since the anti-corrosion coating is smooth and not easy to scale, the overall thermal conductivity of the heat exchanger tube bundle with epoxy-modified urushiolphthalein anti-corrosion is better than that of the heat exchanger without anti-corrosion and scaling Bundle, but still needs further improvement

Abstract

The invention discloses an anti-corrosion coating, belonging to the technical field of coatings. The anti-corrosion coating solves the problems of poor corrosion-resistant effect and short corrosion-resistant life of the traditional coating. The anti-corrosion coating comprises the following raw materials in percentage by weight: 25%-40% of epoxy resin, 25%-40% of modified paint phenolphthalein resin, 5%-10% of titanium nanoparticles, 10%-15% of pigment fillers, 10%-15% of solidifying agents and 15%-20% of solvents. According to the anti-corrosion coating, the solidifying agents are capsule solidifying agents which take ethylene diamine as a core material and polymethyl methacrylate as a wall material and overcome the defects of the traditional epoxy resin solidifying agent, so that the temperature change resistance of the coating can be effectively enhanced; talcum powder and graphite can not only be taken as the components of the pigment fillers, but also have flame-retardant effects. The anti-corrosion coating disclosed by the invention has the advantages of resistance to the corrosion of liquid mediums, such as acid, alkali, salt, organic solvents, oil and the like as well as resistance to boiling water, can be used for a long time in an environment at 220 DEG C, keeps the characteristic of ultra durability of natural raw lacquer, and has no anaphylactic reaction on human bodies.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-corrosion coating. Background technique [0002] With the continuous development of industrial technology and the use of metal materials more and more widely, the corrosion of metal and its components has spread to all fields of the national economy, causing huge losses to human society. In order to reduce the loss of corrosion, people have taken many protective measures, but so far the most common, economical and practical protective measures are paint protection. Among various anti-corrosion technologies, the anti-corrosion technology of paint is the most widely used. It is widely used due to the characteristics of simple construction, economical application, and not being restricted by equipment area and shape. Among the many types of coatings, epoxy resin plays an important role in anti-corrosion coatings. It is widely used as a coating material for metal anti-corro...
