Water-based nano-reflective heat-insulating transparent coating and preparation method thereof

Abstract

The invention discloses a water-based nano reflection and heat insulation transparent coating and a preparation method thereof. The formula of the coating comprises the followings in percentages by weight: 35%-50% of a water-based acrylic emulsion, 5%-15% of water-based lithium silicate, 5%-15% of a water-based polyurethane emulsion, 5%-10% of a water-based heat insulation nano dispersion sizing agent, 5%-10% of a water-based heat insulation and heat preservation nano dispersion, 2%-12% of a wetting dispersant, 0.2%-0.5% of a flatting agent, 0.2%-1% of a thickener, 0.1%-0.2% of an antifungus and anti-mildew agent, 0.5%-2.5% of a coalescing agent, 0.5%-2% of a silane coupling agent and 5%-25% of deionized water. According to the water-based nano reflection and heat insulation transparent coating disclosed by the invention, under the precondition of without influencing lighting, heat radiation is blocked and infrared heat energy is prevented from being conducted into the interior of a base material through effective reflection and heat energy conduction, and thus the effects of heat insulation and heat preservation are reached. Heat energy, entering the room through the base material, generated by an outdoor heat source can be effectively blocked in summer, and indoor heat can be effectively blocked from being dispersed in winter, so that the application of refrigeration and heat preservation equipment can be effectively reduced, and the energy-saving effect is obvious.

Description

technical field [0001] The invention relates to the field of water-based nano-reflective heat-insulating materials, in particular to a water-based nano-reflective heat-insulating transparent coating and a preparation method thereof. Background technique [0002] When the global energy is increasingly tense, in order to alleviate the energy pressure brought about by economic development, major countries in the world have begun to implement energy-saving strategies. With the acceleration of urban and rural construction and the improvement of living standards, the installed capacity of air-conditioning and heating continues to increase, and the proportion of building energy consumption is constantly increasing. Building energy saving has become an important part of the energy saving strategy. An important part of building energy saving is the heat insulation of building doors, windows and glass curtain walls. [0003] At present, the concept of building energy-saving design ha...
