Preparation method of indium tin oxide transparent heat-insulation paint

Abstract

The invention discloses a preparation method of indium tin oxide transparent heat-insulation paint. The preparation method comprises the following steps: (1) based on parts by weight: adding 10 to 20parts of de-ionized water into 20 to 30 parts of nano indium tin oxide; grinding for 30min in a grinding machine with the speed of 400 to 800r / min, so as to obtain nano indium tin oxide slurry; (2) weighing the following raw materials in parts by weight: 50 to 150 parts of waterborne polyurethane, 1 to 3 parts of hollow glass beads, 2 to 5 parts of a thickening agent and 1 to 2 parts of a flattingagent; stirring and dispersing for 10 to 30min under the condition that the rotary speed is 1000 to 2000r / min; then adding 0.5 to 1.5 parts of a de-foaming agent and continually stirring for 5 to 15min to obtain a paint precursor; (3) mixing the nano indium tin oxide slurry in step (1) and the paint precursor in step (2) according to the weight ratio of 1 to (30 to 80); then adding 1 to 3 parts of a dispersant and carrying out ultrasonic dispersion for 1 to 2h to obtain the indium tin oxide transparent heat-insulation paint. The paint disclosed by the invention has relatively good heat insulation performance and also has high light transmittance and has a wide application prospect when being applied to building glass or automobile glass.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a preparation method of indium tin oxide transparent heat-insulating paint. Background technique [0002] With the development of economy, the global demand for energy is increasing day by day. In the ever-increasing total energy consumption, building energy consumption is relatively large. The development of building energy-saving materials is the fundamental way of building energy conservation. For buildings, the heat lost through doors and windows accounts for about 50% of the heating and air conditioning energy consumption of the entire building. However, 60% of the heat loss through ordinary windows is transmitted by infrared rays. Therefore, after the heat convection and conduction of doors and windows are controlled, reducing infrared radiation becomes particularly important. [0003] As a new energy-saving material, transparent insulating water-based nano-coating can...

Problems solved by technology

The key to transparent thermal insulation coatings is the nano-semiconductor material that is selective to sunlight. At present, it is mainly tin antimony oxide. Among them, tin antimony oxide has become an acceptable product in the market due to its relatively low cost, but tin antimony oxide is due to its special nanometer Structural properties, there are problems of easy agglomeration, poor dispersion and low compatibility with the matrix resin, resulting in poor heat insulation effect and low light transmittance of the final heat insulation coating
