This paper presents new thermo-reflective coatings with different properties. Basic, anti-corrosion and self-extinguishing coatings were analyzed. The coatings were obtained with a thickness varying from 1 to 3 mm. The coatings were subjected to detailed tests assessing their physical-mechanical properties, i.e., tensile strength, abrasion, pull-off test, water absorption, vapor permeability and thermal properties, i.e., the thermal performance of the reflective coatings, thermal transmittance, thermogravimetric analysis, differential scanning calorimetry, as well as thermomechanical analysis and thermal conductivity. In addition, the possibility of using such coatings in a wide range of temperatures and during application to various materials used as a substrate, i.e., concrete, metal and rigid polyurethane foam, was tested. The thermal analysis of coatings revealed that materials are stable to temperatures above 200 °C, there are no thermal transitions in the negative temperature region and shrinking in low temperatures is minimal (less than 0.5%). From the data obtained within the framework of this study, it can be concluded that anticorrosive, basic and self-extinguishing coatings are eligible for thermo-insulation applications in temperatures up to 200 °C.
本文介绍了具有不同性能的新型热反射涂层。分析了基础涂层、防腐涂层和自熄涂层。所获得的涂层厚度在1至3毫米之间变化。对涂层进行了详细测试，评估其物理机械性能，即拉伸强度、耐磨性、附着力测试、吸水性、透汽性以及热性能，即反射涂层的热性能、热传递率、热重分析、差示扫描量热法，以及热机械分析和热导率。此外，还测试了在广泛温度范围内以及应用于各种用作基材的材料（即混凝土、金属和硬质聚氨酯泡沫）时使用此类涂层的可能性。涂层的热分析表明，材料在温度高于200°C时稳定，在负温度区域没有热转变，在低温下的收缩最小（小于0.5%）。从本研究框架内获得的数据可以得出结论，防腐涂层、基础涂层和自熄涂层适用于温度高达200°C的隔热应用。
