PRIOR ART

The access efforts to energy sources in the world are among the reasons and determiners of wars and economical and political relations between countries. Pluralities of countries, which are developed and which are developing, needs more energy when compared with the population thereof. In order to meet the energy needs which increase every passing day and in order to release from foreign-source dependence, studies on development of renewable energy sources (wind, sun) and on energy saving are accelerated.

In developed countries, thanks to the energy efficiency decisions provided after 1975s, a very big saving has been provided like 55% in the amount of energy consumed until 2005. In 1990s, more importance has been given to energy efficiency, and as a result of this, total energy consumption in the world has not increased in a parallel manner to growth and has stayed at lower proportions.

The processes realized for decreasing heat passage between two media having different temperatures are called “thermal insulation”. Thermal insulation is used for decreasing the amount of energy consumed for heating in winter and for cooling in summer and for living in a more comfortable manner and thermal insulation is the precautions which decrease heat passage which occurs at external walls of buildings, window glass and joineries, roofs, upholsteries and transmission systems. Humans need mediums at temperatures 20-22 ^e C in order to sustain a comfortable life. In pluralities of regions of Turkey, winter months are substantially cold and the summer months are hot. The insulation material is thick in climates having big number of cold days and the insulation material is thinner in hot regions. Thermal insulation is important not only against cold but also for protection from the hot. The cooling cost in summer is much more than the heating cost in winter. In accordance with nature rules, heat, which is a type of energy, is always transferred from the hot medium towards the cold medium. This transfer cannot be stopped but can be controlled by means of thermal insulation. Heat loss occurs as the heat, which exists in the inner section of a building, moves to the outer medium, and the heat, which exists in the outer medium, moves into the building in summer and heats the medium.

As known, the thermal insulation coating materials used in the art have specific usage durations and it is seen that aggressive medium conditions are not substantially added to the determined usage durations. In this form, coating materials have less usage durations when compared with the estimated durations.

Besides, while coating materials provide thermal insulation, they are in connection with the solar and other thermal energies and this substantially affects the structures of said materials. The materials which provide thermal insulation must be materials which are resistant to thermal energies.

Since the materials used in thermal insulation are essentially in connection with the outer medium, they must also resist to the environmental indications. Particularly for thermal coating materials, ultraviolet radiation, acid-alkali rains and corrosive media are examined as secondary reasons and the coating materials must have high resistance to said conditions.

As a result, because of the abovementioned problems and requirements, a thermal insulation coating material, which can show high resistance against external medium conditions, is required in the related technical field.
