example 1

[0025]Weigh 2 kg of flax stalks and put them into a pulverizer for 30 minutes to pulverize the flax stalks. Wash the flax stalks with a concentration of 1 mol / L sodium hydroxide solution and 0.5 mol / L hydrochloric acid for 8 minutes, and then wash the flax stalks Put the crushed straw into an oven and dry at 110°C for 2 hours to obtain dry crushed matter; put the dried crushed matter into a steam explosion machine, and feed steam preheated to 210°C into the steam explosion machine until it reaches the steam explosion machine. When the pressure reaches 2.2MPa, after keeping the pressure and standing for 2 minutes, open the discharge valve of the steam explosion device, collect the material ejected from the discharge valve instantaneously, then put the obtained material into a frozen pulverizer, and pulverize it for 30 minutes to obtain crushed material. The pulverized material is finally dried by a vacuum freeze dryer for 2 hours to obtain superfine fiber powder; mix antimony tr...

Abstract

The invention relates to a preparation method of nano-sized indium tin oxide heat-insulating glass coating, and belongs to the technical field of coating preparation. The preparation method comprises the following steps: firstly, obtaining multi-hydroxyl group fiber powder through steam explosion; secondly, dissolving antimony trioxide and tin oxide by using nitric acid; thirdly, complexing antimony and tin ions in a mixed solution through complexing of the tartaric acid, and by using sodium hydroxide as a coprecipitant, reacting to produce an antimony and tin crystal nucleus precipitate, wherein hydroxyl groups on the surface of the fiber powder can adsorb crystal nuclei, so that the crystal nuclei are uniformly arranged on the surface of the fiber powder to prevent the crystal nuclei from further growing up, and thus agglomeration of nanoparticles is avoided; finally, calcinating at high temperature to remove a fiber powder carrier to obtain a heat-insulating filler with good dispersion, and then mixing the obtained heat-insulating filler with castor oil, wherein the number of ester groups on the surface of the heat-insulating filler is increased under the action of microorganisms, so that the compatibility of the heat-insulating filler and matrix resin is improved. The finally prepared heat-insulating glass coating is good in heat-insulating effect and high in transparency, and has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a nano-indium tin oxide heat-insulating glass coating, which belongs to the technical field of coatings. 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 c...
