    News: In the modern construction market, the application of
    coatings
    has been concerned, with the acceleration of the pace of environmental protection and energy conservation, intelligent coatings are also becoming a fresh paint force, its wide application prospects for the paint industry will create a considerable market space.
    a long time ago, the Krumanu mixed animal oils or plant proteins with hay ash and applied them to the inner walls of rock caves, ingesting the first coating in history. Until 60 years ago, we were using synthetic wall coatings such as lead whites, vegetable oils and drying agents.
    in mild environments, the coating can last up to about 3 years. Compared with the history of coatings, intelligent coatings are a new concept put forward in recent years.
    The reason why the concept of intelligence is relative to traditional coatings, the traditional sense of coatings generally refers to only protective and decorative properties of coating materials, usually these properties are one-way, that is, this performance can not be changed with the surrounding environment to respond, and "smart" is precisely the opposite, intelligent coatings can change the external environment in a controlled manner to respond to the corresponding feedback, to produce adaptive special properties, so that the coating continues to be effective.
    from the development of intelligent coatings, the realization of intelligent coating performance can be achieved through three basic steps. First, the choice of additives, suitable additives need to have a unique performance performance, enough to meet the formulation of "intelligent" performance requirements, followed by the choice of coating resin substations, pigments and raw materials, such materials from a single performance can not meet the basic properties of the coating, but through formulation matching can meet the basic properties of the coating, including a variety of force properties and resistance, and again to achieve the coating performance feedback on the external environment.
    There are several main types of intelligent coatings in the mainstream, one is environmental feedback type, including sensing coatings, thermal and pressure-sensitive coatings, one is nano-application type, including self-healing coatings, optical coatings, superconducting coatings, etc., one is bioactive, including antibacterial coatings, bio-based coatings, light-induced and bio-induced coatings, and the other is innovative coating materials, including super hydrophobic coatings, self-lubricating coatings and self-sacrifice coatings.
    The conductive intelligent coating developed by the University of Newcastle in the UK to monitor the fatigue of metal structures such as bridges, in the formulation design of the addition of fine ballast crystals, when the crystal is stretched and squeezed, can produce electrical signals proportional to the external force, people can understand the fatigue level of building materials by analyzing these electrical signals.
    In use, as long as the staff in the metal structure surface coating the coating, and then apply a conductive coating, when the voltage is applied, the crystal in the coating and the surface of the component form the correct angle, the metal components no matter what direction the force, the coating can produce the corresponding electrical signal, the greater the force, the stronger the generated electrical signal.
    the American Chemical Society in 2010, scientists announced the successful development of an intelligent coating that "perceives" temperature. Applying the material to the roof not only reflects sunlight in the hot summer months, reducing high electricity bills, but also transforms the role of transporting solar energy to the house and keeping the room warm when cold air strikes.
    in the coating process, waste cooking oil is first liquefied into a liquid polymer that, unlike unprocessed cooking oil, does not give off any taste. In warm weather, asphalt roof temperatures coated with smart paint can drop by 50 to 80 percent, while in cold weather, the temperature can increase by 80 percent.
    coatings are closely related to the scientific development of materials, especially polymeric materials. Nanomaterials technology, which has emerged in recent years, has accelerated the rapid progress of intelligent coatings. In addition, the promotion of environmentally friendly environmental requirements, but also to a large extent to promote intelligent coatings in the water-based, solvent-free, high-solid, energy curing,
    powder coatings
    and other fields of breakthrough.
    Although the future field of coating development can not be absolutely accurately predicted, but it is clear that with the emergence of intelligent technology and micro-technology development, paint product differentiation, the impact on society, will be dramatic changes in the coming decades, it will help us paint a better future.
