Abstract

The invention discloses a reflecting thermal insulating paint which comprises the following components in parts by mass: 70 parts to 80 parts of water, 85 parts to 100 parts of rutile type titanium dioxide, 35 parts to 40 parts of cenosphere, 10 parts to 12 parts of far infrared ceramic powder, 6 parts to 10 parts of dispersing agent and 230 parts to 250 pars of pure elasticity acrylic emulsion. The invention also provides a preparation method of the reflecting thermal insulating paint. The reflecting thermal insulating paint belongs to water-based paints, has the advantages of safety and environment protection, has the thermal insulating temperature higher than 10 DEG C, has extensibility,crack resistance and wide application.

Description

Technical field: [0001] The invention relates to the technical field of coatings, in particular to a solar heat-reflecting heat-insulating coating used for building exterior surfaces (including walls and roofs) and industrial storage tanks and a preparation process. Background technique: [0002] Human beings actively develop solar energy to save limited resources. However, the heat generated by the intense radiation of the sun also brings a lot of inconvenience to people's lives. In developed countries, the energy used by cooling equipment such as air-conditioning units, air-conditioning equipment and electric fans accounts for more than 20% of the total annual energy consumption; In China, the energy consumed by these devices is as high as about 41%, and there is an increasing trend every year. The excessive loss of these energy sources has a lot to do with the thermal insulation measures taken by buildings. [0003] In order to reduce the increase of the external enviro...
