Light-colored waterborne heat-insulation coating and method for preparing same

Abstract

The invention discloses light-colored waterborne heat-insulation coating and a method for preparing the same. The light-colored waterborne heat-insulation coating comprises, by weight, 10-30% of water, 1-3% of texanol, 1-3% of propylene glycol, 0.1-0.5% of organosilicon, 0.05-1% of polycarboxylic acid ammonium salt, 0.03-1.1% of isothiazolinone, 0.03-1.1% of sodium alkylarysulfonate, 10-30% of titanium dioxide, 8-18% of high-reflection macromolecular compounds, 5-35% of acrylic acid emulsion, 0.24-1% of polyacrylate, 5-35% of calcium carbonate, 0-10% of color paste and 0.1-0.5% of celluloses. The light-colored waterborne heat-insulation coating and the method have the advantages that the light-colored waterborne heat-insulation coating is applicable to carrying out heat-insulation and anti-seepage treatment on roofs, balconies and cement asbestos tile surfaces, can be used for heat-insulation cooling treatment on metal tile surfaces and outdoor metal storage tanks, is excellent in weather resistance, pollution resistance, abrasion resistance and scrub resistance, is waterborne, environmentally friendly, non-toxic and tasteless and can be easily, conveniently and quickly constructed, energy can be obviously saved, power consumption can be obviously reduced, and the temperatures of coatings can be reduced by 10 DEG C at least under the burning sun; the light-colored waterborne heat-insulation coating can be adjusted to have diversified light colors according to decoration aesthetic requirements and has durable heat-insulation functions.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a light-colored water-based heat-insulating coating and a preparation method thereof. Background technique [0002] At present, with the development of society and the improvement of people's living standards, more attention is paid to energy saving, environmental protection and safety in the selection and use of building materials. For architectural coatings with decorative, protective and livable improvement functions, energy conservation, environmental protection and safety are particularly important, and they are also effective measures for the implementation of energy conservation and emission reduction targets in various countries. A series of energy-saving and environmentally friendly architectural coatings have emerged, the most typical of which are white roof coatings and white or light-colored wall coatings, which can significantly reduce the temperature inside buildings and all...

AI Technical Summary

Problems solved by technology

Domestic heat insulation coatings for buildings are mainly inorganic silicate barrier heat insulation coatings and reflective heat insulation coatings that have been developed in recent years. Although these two types of heat insulation coatings have good heat insulation effects , but they are all white and have a very high amount of pigments and fillers, basically no decoration

Moreover, the VOC emitted during the construction of oil-based thermal insulation coatings used today not only affects the comfort of construction, but also causes air pollution

Ordinary water-based thermal insulation coatings can only be made into white or near-white coatings. When the surface of the coating film is polluted or the coating film ages and discolors, the heat insulation effect drops rapidly, or even loses the heat insulation function. The effective time of heat insulation is generally Only about 3 years, relatively short, this kind of heat insulation effect is not obvious, even without a little heat insulation effect, especially when it is applied to the heat insulation of dark building surfaces, the heat insulation effect is very inconspicuous
