Crosslinking agent for anti-icing coatings
The basic principle of superhydrophobic surface was introduced briefly in wuhan university of science and technology, and the preparation technology and the latest achievements of superhydrophobic coating were studied in two aspects of superhydrophobic structure construction.
Hydrophobic coatings with low surface energy can be prepared by using the preparation method of RTV antifouling flash coating. Such as selection of production of a certain institute 107 room temperature vulcanized silicone rubber as film forming material, and using stannous octylic acid catalyst, vinegar is four butyl titanate as crosslinking agent, the preparation of a kind of low surface energy of hydrophobic coating.
In this way, a rough structure is constructed, which is the structure of nano-nano-nano-nano-nano-nano-nano-nano-nano-nano-nanoparticles and the chemical grafting intensity.
The study of anti-icing technology and the methods of prevention measures are of great significance to improve the safe operation of power system. Especially along with the development of the western region the scale enlargement of cwe resources construction, long distance conveying electricity through cold, high humidity and high altitude, line ice disaster problem will become more prominent, how to prevent ice deicing technology has become one of the key technologies.
And upgrade to strengthen the construction of the uhv transmission lines becomes the key point of the development of the electric power industry, to line the requirement of ice is strengthened, the high performance of preventing ice materials and technology has become the urgent request of the security and stability of electric power.
Research at home and abroad in recent decades and explored a variety of anti-icing de-icing method, from the classification, the ease and improve the state of the transmission lines ice measures mainly has two kinds, namely the anti-icing and de-icing technology. The anti-icing technology of transmission lines is mainly designed to avoid overlying areas when designing transmission lines. The technology at home and abroad has more than 30 kinds, can be divided into four categories: thermal de-icing method, mechanical de-icing method, passive de-icing method and other methods, in addition to the above method, electronic freeze, corona discharge and collision particles before freezing and heating method is also being studied.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
Among them, passive anti-icing method does not need to consume additional energy, so this method is first considered in engineering applications. In all passive anti-icing methods, the method of using hydrophobic and ice-resistant coating has aroused wide interest. On the basis of this, it is necessary to strengthen the research and development of anti-icing coatings.
Current anti-icing technologies are generally energy-intensive and have no safe and effective methods. It is a feasible way to solve the above problems by developing a special water-repellent coating.
The coating on metal substrate not only has a good combination of resistance and good thermal conductivity, at the same time, the surface coatings with low surface energy, high hydrophobic, hate ice and spectral absorption of heat, can reduce the water and ice on the adhesion, makes it easy to fall off, so as to achieve the purpose of preventing ice. This method is easy to operate, easy to control, low cost, and has good prospect for the use effect.
In addition, the coating product prices generally low, construction is convenient, not only can be used in power transmission and transformation line, also can be widely used in iron tower, pole, insulator and related fixed piece of equipment, especially in the mountains, hills, forest regions such as power equipment, can significantly reduce the amount of ice of line and delay the formation of ice.
The anti-icing principle of anti-icing coatings generally has two ways of thinking: firstly, the heat source is used to improve the temperature of the coated surfaces and prevent the cooling water from freezing. The second is to minimize the bonding between the ice and the substrate, making it easy to fall off and remove.
Anti-icing coating can be divided into four categories: 1. Electrothermal coating; Hot paint; 3. Hydrophobic coatings; 4. Super hydrophobic anti-lotus leaf coating. Among them, the leaves on the surface of super hydrophobic and self-cleaning effect is known as a self-cleaning effect of lotus leaf or "lotus effect", people according to the hydrophobic mechanism of lotus leaf preparation with "lotus effect" super hydrophobic surface and coating.
