Embodiment 1

[0018] The main purpose of the present invention is transparency and heat insulation. The components and their proportions (parts by weight) used in this embodiment are: water-based polyurethane 500, nanometer tin oxide antimony oxide doped powder conductive paste 500, film forming Additive 5, leveling agent 2, defoamer 2, anti-scratch agent 2, ultraviolet absorber 2. Among them, alcohol ester 12 is used as film-forming aid, and anionic liquid light stabilizer is used as ultraviolet absorber. The leveling agent, defoamer, and anti-scratch agent used in the present invention all adopt the stock solution product of German Degussa Company.

Embodiment 2

[0020] In this embodiment, the components and their proportions (parts by weight) used in the present invention are: acrylate emulsion 550, nano-indium oxide tin oxide doped powder conductive paste 450, film-forming aid 6, leveling agent 2. Defoamer 2. Anti-scratch agent 2. Ultraviolet absorber 2. Among them, alcohol ester 12 is used as film-forming aid, and anionic liquid light stabilizer is used as ultraviolet absorber.

[0021] Among the above-mentioned components of the nano-transparent heat-insulating coating, the water-based polyurethane can be replaced by a hydrophilic fluorocarbon emulsion; the acrylate emulsion can be replaced by a modified silicone acrylic emulsion.

[0022] The preparation method of above-mentioned nanometer transparent thermal insulation coating is as follows:

[0023] a. Put the water-based polyurethane or acrylate emulsion of the above weight ratio into a clean stainless steel dispersing kettle;

[0024] b. Add film-forming aid alcohol ester 12...

Abstract

The invention relates to a nano transparent heat-insulating dope and a preparation method thereof. The dope is made from the following components in portion by weight: 450 to 550 portions of transparent film forming substances, 450 to 550 portions of nano oxide doped powdered conductive paste and 10 to 15 portions of auxiliary agent. The nano oxide doped powdered conductive paste comprises the following components in portion by weight: 1 to 5 portions of dispersant, 150 to 200 portions of tin oxide and antimony oxide doped powder or indium oxide and tin oxide doped powder and 800 to 850 portions of deionized water. The dope of the invention has advantages of low cost, simple and convenient construction, high transparency, obvious heat-insulating effect and the like. For example, when a layer of transparent dope film with a thickness of about 30 mu m is coated on the surface of glass, the daylighting of the glass is not influenced and the solar heat radiation is effectively insulated to produce a difference of 6 to 8 DEG C between indoor and outdoor temperatures.

Description

technical field [0001] The invention relates to a heat-insulating coating and a preparation method thereof, in particular to a nano-transparent heat-insulating coating and a preparation method thereof. The coating of the invention is mainly applied to the surface of transparent carriers such as building glass, vehicle and ship glass, organic glass and the like. technical background [0002] The main ways of traditional technology to solve the problem of glass heat insulation are: one is to use heat insulation film, but its price of more than 200 yuan per square meter is unbearable for ordinary people, and it is only used in high-end cars at present; Reflects heat, but the opacity and light pollution caused by this product prevents its widespread use. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical deficiencies existing in the existing glass heat insulation materials, and provides a nano transparent heat insulation coati...
