ThermocinétiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Paints and coatings are typically used to beautify and protect, but there are many examples of specialty coatings that serve other functions. The development of these "functional" coatings has been a trend in the industry for many years, and there are numerous examples such as soft-feel coatings for consumer electronic, sound-damping coatings for mitigating noise in automobiles, and antimicrobial coatings designed to kill microorganisms that come into contact with the coated surface.
Another trend in the paint and coatings industry has been the development of coatings that control the use of energy.
Access to energy is an important global driver for economic growth, and how we generate, efficiently use, and ultimately conserve energy has important consequences for the future of our environment and society. Coatings technology has an important role to play in this ongoing struggle. For example, coatings that can be cured at lower temperatures inherently use energy more efficiently.
The replacement of heavier bitumen pads with lightweight liquid-applied sound-damping coatings allows auto manufacturers to remove weight from automobiles. Reducing weight of transportation vehicles uses energy more efficiently and improves mileage. Antifouling coatings help the fuel efficiency of ships by preventing the buildup of biofouling on the hull, which increases drag and makes engines work harder to achieve the same result. Several types of functional coatings are targeted at managing thermal energy. Cool-roof coatings keep the interior of buildings cooler and lighten the load on air conditioning during the hot, sunny days of summer. High solar reflectivity and thermal emissivity helps the coating deflect energy in sunlight, preventing the roof from heating up as much, and thus less heat is conducted through the roof and into the building. Cool coatings for exterior building walls also function in a similar manner. Cool coatings also help defend against the urban heat island effect, where urban environments with large areas of dark roofs and paved surfaces tend to be warmer than nearby rural areas. Thermal insulation coatings are also used to manage thermal energy for both personnel protection and energy conservation purposes. However, thermal insulation coatings rely on a different mechanism and prevent heat transfer between materials due to their low thermal conductivity.
In this article, we introduce thermal insulation coatings and the science behind how they work. First, a discussion on the physics of heat transfer and thermal conduction will provide some necessary context to understand how insulation works. A description of traditional insulation materials and some lingering problems with those materials will give perspective into why thermal insulation coatings were developed, followed by a description of how thermal insulation coatings are formulated, applied and perform. A brief comparison with cool-roof coatings will also be given to clarify common misunderstandings about functional coatings and how they each help with energy management.Note de contenu : - Mechanisms of heat transfer

ThermocinétiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : A mixture of etherified melamine–formaldehyde and acrylic emulsion resin was designed, with the hybrid resin improving the fire retardancy of indoor plywood as well as the CO and CO2 emissions. The water-based hybrid resin exhibited a single curing peak; the need for solvents was reduced. Compared with pure etherified melamine–formaldehyde resin, the hybrid resin had better flame retardancy and produced less pollution. Scanning electron microscopy and cone calorimetry were conducted, and the analyses revealed that lower binder resin concentrations resulted in improved flame retardancy and better char layer formation. When the binder resin concentrations were increased and CO/CO2 emissions were continued beyond 300 s, the flame retardancy of the intumescent coating was the same as that of the lower binding resin concentrations. Furthermore, the chemical structure and durability of the phosphocarbonaceous structure were verified through Fourier transform infrared spectroscopy and solid-state nuclear magnetic resonance analyses.

Traitement thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Thermally modified wood (TMW) is increasingly used in exterior applications as an alternative to tropical hardwoods or wood impregnated with biocides. Despite its enhanced biological durability and dimensional stability, a surface treatment of TMW with coating systems can be required in certain applications. This study assessed material characteristics of Norway spruce and Scots pine wood that was thermally modified according to the ThermoWood® process and their effect on the performance of commercially available coating systems: a solventborne oil, a waterborne alkyd-reinforced acrylate paint and a waterborne acrylate paint. Residual extractives and remaining degradation products found in TMW, carry the risk of causing discoloration or of interfering with the curing reactions of coating systems. The penetration of coating systems into TMW was not found to differ from unmodified wood, although an excessive penetration of solventborne oil was found occasionally for TMW. The adhesion strength of waterborne coatings depended on the system that was used. While one system performed sufficiently on TMW, the other coating systems showed a considerable reduction in adhesion strength already after a mild treatment (<200°C). This reduction could not be attributed to the increase in hydrophobicity of TMW that was evident from contact angle measurements, but was rather related to the mechanical interaction of the specific substrate/coating system.

Traction (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : Acrylic-based latex blend coatings, comprising a hard (Tg=45°C) and soft (Tg= -5°C) phases are evaluated in terms of the total energy they absorb before failure in a tensile test. Simultaneous measurement of the work and heat of deformation using a novel technique of differential gas pressure stretch calorimetry enables an estimate of change in their internal energy by application of the first law of thermodynamics. As the hard phase content of the blend is increased from 0-100%, its stiffness and tenacity increase, while the toughness (i.e., the energy to failure) undergoes a maximum at an intermediate composition. A partitioning of the mechanical work into heat and internal energy over the complete range of blend composition highlights the result that a simultaneous maximization of the heat dissipation and energy absorption is necessary to maximize blend toughness. This provides a new framework in which the properties of blend systems can be tailored in terms of their stiffness and toughness to design improved coatings.
