Problems solved by technology

Through the treatment of the roof, such as coating the heat-insulating and heat-dissipating paint layer on the roof is one of the means to stabilize the indoor temperature. The traditional roof is often poured with asphalt, which is not easy to achieve thermal insulation effect in winter, and the heat dissipation effect in summer is also poor. , and planting green plants on the roof can effectively avoid the shortcomings of the asphalt roof, but the green roof has relatively high requirements on the building itself, such as drainage, load-bearing capacity, etc.
[0003] At present, there are cases of heat-insulating coatings on the market, which mainly reduce the energy absorbed by the wall and reduce heat conduction by reflecting infrared light to save energy. Although infrared light-reflecting coatings reduce the infrared light Absorption achieves cooling, but the coating itself does not have heat dissipation performance, and the heat absorbed by it will directly cause fluctuations in the indoor temperature through the heat transfer of the wall, making the indoor temperature stability poor, which increases the energy consumption to achieve indoor constant temperature , so that the effect of energy saving and environmental protection is poor, and this kind of coating layer is not resistant to aging, the adhesion is not strong, and it is easy to be washed away by rain

Abstract

The invention discloses a heat dissipating organic silicone coating for roofs. The coating comprises an A component and a B component, wherein the A component is formed by mixing of propyltriethoxysilane, dimethyldiethoxylsilane, alcohol, titanium dioxide, aluminum oxide, bentonite and water, and the B component is formed by mixing of a titanium complex, dibutyltin dilaurate and a coupling agent;and the A component and the B component are uniformly mixed when being used. The heat dissipating organic silicone coating for the roofs disclosed by the invention has good heat dissipation performance, strong adhesion, impact resistance, high-temperature resistance, convenient use, and curing time and effects which can be adjusted according to actual conditions.

Description

technical field [0001] The invention relates to the field of roof heat dissipation coatings, in particular to a roof heat dissipation silicone coating. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, as well as the improvement of architects' design concepts, buildings are becoming more and more high-end and multi-functional. Among them, maintaining the stability of the indoor temperature is one of the requirements for the building. In this way, through the treatment of the building wall or roof, the heat transfer from the outdoor temperature to the indoor is avoided, so as to ensure that the indoor is stable and relatively stable, thereby reducing the energy consumption to achieve a constant indoor temperature, thereby effectively realizing energy saving and environmental protection. . Through the treatment of the roof, such as coating the heat-insulating and heat-dissipa...
