Abstract
The invention discloses an environmental-protective energy-saving aqueous radiation heat-insulating coating which is characterized by being made from following raw materials, by weight: 23-25 parts of a cordierite-based composite infrared radiation material, 33-36 parts of pure acrylic emulsion, 5-7 parts of natural latex, 7.5-8.5 parts of rutile titanium dioxide, 22-25 parts of anhydrous ethanol, 1-2 parts of sodium polyacrylate, 4-5 parts of hollow micro-spheres, 1-2 parts of linseed oil, 0.8-1 part of hydroxypropyl methyl cellulose, 0.5-0.7 parts of sodium polyphosphate, 26-28 parts of deionized water and 0.6-0.8 parts of glyceryl stearate. The coating is reasonable in component formula. By means of addition of the cordierite-based composite infrared radiation material prepared through special processes, the coating is improved in infrared emitting rate, which is beneficial to heat insulation and temperature decreasing. The rutile titanium dioxide and the like are subjected to surface activation and then are mixed with other components, so that the coating is less in granularity, is good in coating film adhesivity, and can reduce indoor/outdoor temperature difference, thereby reducing energy consumption of an air conditioner. The coating can save energy and reduce emission and is valuable to popularize.
Description
Technical field
The present invention relates to technical field of coatings, particularly a kind of environment-friendly and energy-efficient water-based radiation heat insulation coating and preparation method thereof.
Background technology
Coating Water-borne modification is protection of the environment and the common prescription saving petroleum resources.Water-borne coatings take water as primary solvent, to human body and environmental hazard little, and have easy construction, security good, be easy to store the features such as transport, oneself becomes the important development direction of modern coatings.Current water-borne coatings is widely applied in building coating field.
Thermal insulating coating is the thermal accumlation being reduced coated article inside by mechanism such as obstruct, reflection, radiation, thus reaches energy-conservation a kind of functional coating with improving the object such as Working environment or safety.General thermal insulating coating is divided into isolation-type, reflection-type and Radiation Heat-insulated Paint three class.Wherein, Radiation Heat-insulated Paint is by transferring the UV-light in the sun power absorbed, visible ray and near infrared luminous energy to heat energy, in 8-13. 5 mu m waveband, pass air infrared window in the mode of ir radiation, be transmitted into air skin efficiently, thus reach the object reducing temperature.The distinguishing feature that Radiation Heat-insulated Paint is different from other two classes thermal insulating coatings is: all the other two class thermal insulating coatings can only slow down but can not the transmission of block heat, and Radiation Heat-insulated Paint can fall with the heat radiation of the form of heat emission by absorption, thus impel that coating is inside and outside lowers the temperature with same speed.
In recent years, along with the continuous quickening of national Development of China's Urbanization, rapidly, the living environment of people is constantly improved in building industry development.But because the building of the overwhelming majority does not adopt energy-saving structure and energy-saving material, cause building energy consumption to account for very large proportion in Chinese society total energy consumption, therefore researching and developing energy-saving building materials has become to reduce building energy consumption the instant problem that current social will solve.
