Embodiment 1～7

[0037] Under the condition of 20°C, the required amount of resin, inorganic salt, surfactant, alcohol and water are mixed to prepare microemulsion resin. Then mix the required amount of nanometer powder, coating additives and the prepared microemulsion resin, and stir to prepare the thermal insulation coating compositions A to G for glass.

[0038] The components and weight percentages of each coating composition are shown in Table 1.

Abstract

This invention relates to a method for preparing heat-insulating paint composition for glass. The heat-insulating paint composition comprises: micro-emulsified resin 20-60 wt. %, nanopowder (20-150 nm) 15-40 wt. %, and paint additive as balance. The micro-emulsified resin comprises: at least one of organosilicon resin, inorganic silicon resin, alkyd resin, epoxy resin, acrylate and polyurethane 50-80 wt.%, inorganic salt 0.001-5 wt.%, at least one of anionic, cationic and nonionic surfactants 0.001-8 wt.%, C1-C5 lower fatty alcohol 1-20 wt.%, and water as balance. The heat-insulating paint composition has such advantages as high heat insulation performance, high transparency, and high hardness, and can be used on building glass and automobile glass.

Description

technical field [0001] The invention relates to a thermal insulation coating composition for glass and a preparation method thereof. Background technique [0002] The main source of heat for Earth's biosphere is the sun. The energy transfer is mainly based on sunlight, and through radiation, convection and conduction, the earth's environment absorbs heat and needs to release heat to achieve a suitable living and working temperature. At the same time, most buildings use glass as a window for lighting and viewing; however, glass will strengthen the ability to receive sunlight and be affected by the environment. According to analysis, the energy consumption of buildings accounts for 27% of the energy consumption of the whole society, and the doors and windows in buildings account for 40% of the energy consumption of buildings; In order to maintain a suitable temperature in the room, energy must be consumed. More than 40% of indoor energy consumption in metropolitan cities is...
