Environmental-protective energy-saving aqueous radiation heat-insulating coating and preparation method thereof

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 [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly and energy-saving water-based radiation heat-insulating coating and a preparation method thereof. Background technique [0002] Water-based paint is a common requirement for protecting the environment and saving petroleum resources. Water-based coatings use water as the main solvent, which is less harmful to the human body and the environment, and has the characteristics of convenient construction, good safety, and easy storage and transportation. It has become an important development direction of modern coatings. At present, water-based coatings have been widely used in the field of architectural coatings. [0003] Heat-insulating coating is a functional coating that reduces the heat accumulation inside the coated object through mechanisms such as barrier, reflection, and radiation, so as to achieve energy saving and improve the working environment or ...
