Embodiment 1

[0043] The preparation method of the spherical heat-insulating nanomaterial provided in this example, the specific steps are as follows:

[0044] a) Weigh 0.3g SnCl 4 , dissolved in 80mL deionized water;

[0045] b) Stirring with magnetic force at room temperature for 10 minutes to obtain a light blue transparent solution 1;

[0046] c) Weigh 2.6058g SnCl 4 (10mmol) and 0.1141g SbCl 3 (0.5mmol), so that the molar ratio of Sb:Sn is (1:20), the two are dissolved in an appropriate amount of 2mol / L hydrochloric acid solution to obtain a colorless and transparent solution 2;

[0047] d) Dilute the ammonia solution to 1:1 for later use to obtain solution 3;

[0048] e) At 60°C, add 0.1g of cetyltrimethylammonium bromide, and use the double drop method to slowly and uniformly drop solutions 2 and 3 into solution 1 while stirring, so that the doping element antimony is in the system The concentration is 0.005mol / L, and the pH of the control solution system is less than 3;

Abstract

The invention discloses a preparation method and application of a spherical thermal insulating nanometer material. The preparation method comprises the following steps of: preparing a heat reflection spherical nanometer material ATO (Arsenic Trioxide)by adding a morphology control agent by means of a co-precipitation method; carrying out mixing and ball milling on film forming agents and the well dispersed heat reflection spherical nanometer material ATO to obtain a paint, wherein the film forming agents comprise polyurethane, acrylic resin and epoxy resin; and coating the paint on a glass and transparent resin material. The prepared film coating has good thermal insulation and transparent conductivity effects, light transmissivity of the transparent conductive film coating in a visible light region is more than 80%, light transmissivity of the transparent conductive film coating in an infrared light region is less than 20%; compared with blank glass, the temperature of the glass coated with the thermal insulating transparent conductive paint can be reduced by 5-10 DEG C, and the thermal insulating transparent conductive paint has excellent thermal insulation and transparent conductivity effect; and compared with the prior art, the product has the effects of stable chemical property, high transmissivity in the visible light region, low transmissivity in a near / far infrared light region, excellent thermal insulation performance and the like, and is easy to store for a long term.

Description

technical field [0001] The invention relates to a preparation method of a spherical heat-insulating nanometer material and an application of the spherical heat-insulating nanometer material in preparing a heat-insulating transparent conductive film. Background technique [0002] At present, energy saving and new energy exploration have become important issues in the world. [0003] In high-rise buildings, transparent ceilings, automobiles, exhibitions and other occasions that require good lighting, the glass used has higher requirements for the permeability of visible light. Since the transmission selectivity of ordinary glass to the solar spectrum is not high, when visible light passes through, a large amount of heat in the infrared region will also pass through the glass, resulting in an increase in indoor temperature, which greatly increases the burden on air conditioners. Thereby causing waste of energy. [0004] In order to save energy, people have invented heat-refle...
