Thermal-insulation slurry and preparation method thereof, water-based insulating glass coating and preparation method thereof

Abstract

The invention provides thermal-insulation slurry and a preparation method thereof, and water-based insulating glass coating and a preparation method thereof. The thermal-insulation slurry is made from nano-scale graphene oxide and nano-ATO mainly; as the nano-ATO has special optical property, in other words, the nano-ATO has high rejection rate in both the long-wave part of an infrared region and an ultraviolet light region, has high transmittance in a visible region, and meanwhile, as the nano-scale graphene oxide has high thermal insulation efficiency, reflection of radiation of the infrared region can be enhanced effectively, and the defect of poor thermal insulation property of the nano-ATO to the near-infrared short-wave region is overcome. The water-based insulating glass coating is prepared from the thermal-insulation slurry and high-transparency high-adhesion water-soluble polyacrylic resin, so that defects of low transparency and poor thermal insulation effect of the prior art are overcome, the problem about poor thermal-insulation property to the near-infrared short-wave region is solved, and the water-based insulating glass coating keeps stable and uniform for a long time.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a heat-insulating slurry and a preparation method thereof, and a water-based heat-insulating glass coating using the heat-insulating slurry and a preparation method thereof. Background technique [0002] After more than 30 years of high-speed economic development, my country has become the second largest economy in the world, but at the same time it has also caused great energy consumption and waste. China has nearly 40 billion square meters of existing buildings, 95% of which are not energy-efficient buildings. The new national building energy-saving standards stipulate that new buildings must achieve 50% energy-saving. At present, my country's building energy consumption accounts for 40% of the total energy consumption, and the energy lost through doors and windows is 46%. Therefore, building energy conservation must first be grasped from doors and windows. In recent years, large windo...
