Abstract

The invention relates to a thermal insulating coating widely applied to glass substrates, in particular to a water-based hydrophobic nano-resin, a glass thermal insulation coating and a preparation method. The waterborne hydrophobic nano-resin is prepared by mixing and reacting 10 to 40 percent of the solution of vinyl nano-oxide, 0.5 to 4.0 weight percent of emulsifier, 30 to 60 weight percent of acrylate monomer, 5 to 30 weight percent of fluoroacrylate monomer, 3 to 12 weight percent of vinyl siloxane, 0.1 to 4 weight percent of initiator, 0.5 to 2 weight percent of neutralizer and 5 to 30 weight percent of de-ionized water. The method comprises the following steps of: from the standpoint of chemical grafting, first preparing a nano-oxide containing vinyl; then synthesizing the hydrophobic nano-resin by copolymerizing the nano-oxide with a free radical of a fluoro (silicon) acrylic monomer; and finally preparing the hydrophobic glass thermal insulating coating by using the resin. The glass thermal insulating coating has the advantages of high comprehensive performance, thermal insulation, contamination resistance and aging resistance, and wide market prospect in the environmentally-friendly society.

Description

Technical field: [0001] The invention relates to a heat-insulating coating widely used on glass substrates, in particular to a water-based hydrophobic nano-resin and glass heat-insulating coating and a preparation method. Background technique: [0002] With the rapid growth of our country's economy, environmental and energy issues have attracted more and more attention. The glass doors and windows of buildings have poor heat insulation effect, resulting in huge waste of energy. The research and development of new energy-saving products and the reduction of electricity load are of great significance to alleviating the energy shortage in our country at this stage. In order to save energy, people have adopted various measures To solve the heat insulation problem of building glass. At present, metal-coated heat-reflective glass and various heat-reflective films are mainly used in the market to block the penetration of part of the sunlight, so as to achieve the purpose of heat i...
