Embodiment 1

[0021] First add 69kg of DMF into the blending pot, then add 5kg of fatty alcohol polyoxyethylene ether, 10kg of PU resin, and 0.5kg of PMA in turn while stirring, until they are all dissolved evenly, and finally add 0.5kg of UV-9, 15kg of antimony oxide, and mix thoroughly. Then carry out ultrafine grinding for 30 hours, so that the particle size of the antimony oxide particles is nanoscale, stop grinding, filter, compound after filtering, filter again, and discharge after detection.

Embodiment 2

[0023] First add 92.6kg DMF into the blending pot, then add 2kg fatty alcohol polyoxyethylene ether, 5kg PU resin, and 0.2kg PMA in turn under stirring until all are dissolved evenly, and finally add 0.1kg UV-9, 0.1kg antimony oxide, and stir thoroughly Mixing, and then superfine grinding for 12 hours, so that the particle size of the antimony oxide particles is nano-scale, stop grinding, filter, compound after filtering, filter again, and discharge after detection.

Embodiment 3

[0025] First add 80.9kg DMF into the blending pot, then add 3.5kg fatty alcohol polyoxyethylene ether, 7.5kg PU resin, 0.35kg PMA in turn under stirring until all are dissolved evenly, and finally add 0.25kgUV-9, 7.5kg antimony oxide, fully Stir and mix, then carry out ultrafine grinding for 21 hours, so that the particle size of the antimony oxide particles is nanoscale, stop grinding, filter, compound after filtering, filter again, and discharge after detection.

[0026] After testing, the nano-scale infrared insulating glass energy-saving coating obtained by adopting the technical solution of the present invention has main physical performance indicators shown in Table 1.

[0027] Test items

Abstract

This invention relates to a method for producing nanoscale energy-saving glass paint with IR-isolating performance. The glass paint comprises: UV absorbent 0.1-0.5%, IR absorbent 0.1-15.0%, dispersant 2.0-5.0%, surface wetting agent 0.2-0.5%, resin 5.0-10.0%, and solvent 69-92.6%. The method comprises: adding solvent into a mixing pot, stirring, adding dispersant, resin and surface wetting agent to complete dissolution, adding UV absorbent and IR absorbent, stirring, performing ultrafine grinding for 12-30 h so that the granularity D50 is 40-100 nm, ending grinding, filtering, compounding, filtering, and discharging. The obtained glass paint is transparent, and can absorb UV and IR. Glass coated with the glass paint can prevent UV and IR while is permeable to visible light. The glass paint has such advantages as good UV and IR absorbency, high heat resistance, high durability, high hardness, and high dispersibility, and can be used on building glass and automobile glass.

Description

technical field [0001] The invention relates to a glass energy-saving coating, in particular to a nano-scale infrared-insulating glass energy-saving coating and a manufacturing method thereof, belonging to the technical field of new energy-saving materials. Background technique [0002] At present, the heat insulation of architectural glass materials marketed in the market mainly adopts the following measures: (1) film, which is expensive and only suitable for high-end automotive glass; (2) reflective film, which is difficult to be widely used due to its opacity, and the reflection will A certain amount of light pollution is produced; (3) Double-layer insulating glass has good transparency. Although it is widely used, its infrared and ultraviolet shielding rate is low, its heat insulation performance is poor, and its production cost is high, and its waste of resources is large. [0003] A nano-scale infrared insulating glass energy-saving coating, which can well overcome the...
