Problems solved by technology

The disadvantage is that the firmness of the film layer is not high, it is easy to oxidize and deteriorate over time, and the life cycle is limited
As another example, the PET low-emissivity film or XIR film used in China CN1307969 "Low-E laminated glass containing PET film" is a patented product of Southwall (Shaohua) in the United States. Small, and the XIR membrane instrument is wrinkled
Another example is the Chinese CN 2820861Y "heat-reflective laminated glass" that uses a polymer material as a heat-insulating functional film and PVB material to form a film by hot rolling, so that the visible light transmittance of the material is not high, only 70%.

[0022] ATO

Embodiment 1

[0023] Embodiment 1: get 20kg polyethylene type resin and be dissolved in the mixed solvent of the ethanol of 43.2kg and n-butanol, add the nano material body slurry 30kg that makes by above-mentioned proportion 1 again, and leveling agent 1.0kg, defoaming agent Add 0.8kg of solvent, 2.0kg of dispersant, and 3.0kg of adhesion promoter, and stir evenly to prepare a transparent heat-insulating coating. Coat the prepared transparent heat-insulating coating on the surface of the glass substrate to make heat-insulating glass, and heat it to dry and cure. The drying temperature is 60°C, and the coating film is dry for 5 minutes, and the coating film is dry after drying at 100°C for 3 minutes. The dry film thickness is 30um. Then laminated glass is made from this heat-insulating glass, the visible light transmittance is 85%, the infrared shielding rate is 75%, and the heat insulation lowers the temperature by 7°C.

Embodiment 2

[0024] Embodiment 2: Get 44kg acrylic resin and dissolve in the mixed solvent of 32kg of acetone and butanol, then add 20kg of nano material body slurry made by the above proportion 2, and 0.7kg of leveling agent, 0.6kg of defoamer kg, 1.1kg of dispersant, and 1.6kg of adhesion promoter, and stirred at a high speed to obtain a transparent heat-insulating coating. Apply the prepared transparent heat-insulating coating on the surface of PET film to prepare a laminated glass interlayer film, and dry it with heat at 60°C for 12 minutes to dry the film, with a dry film thickness of 35um. Then laminated glass is made from this laminated glass interlayer film, the visible light transmittance is 82%, the infrared shielding rate is 70%, and the heat insulation and temperature reduction are 6°C.

Abstract

The invention relates to an insulating mould coating, a laminated glass intermediate film, a piece of heat-protecting glass and a piece of laminated glass thereof. The transparent insulating mould coating is prepared by dissolving a thermal plastic macromolecule resin into a solvent, then adding a nanometer material body sizing agent and other auxiliary agents and stirring the mixture evenly. Theinsulating mould coating can be coated on glass and transparent resin film materials, and has very strong bonding strength, and refraction coefficients similar to that of the glass and the laminated glass intermediate film; and the insulating laminated glass prepared by using the insulating mould coating has the characteristics of high visible light transmittance, infrared ray shielding, heat insulation, ultraviolet ageing resistance and the like. The insulating mould coating is simple to prepare, needs no large-scale equipment, and is favorable for popularization.

Description

Technical field: [0001] The invention relates to a paint, in particular to a transparent heat-insulating paint, and a laminated glass interlayer and heat-insulating glass with heat-insulating function using the heat-insulating paint, as well as a glass made of the heat-insulating glass and the laminated glass interlayer into laminated glass. Background technique: [0002] In general, laminated glass has a structure in which at least one pair of glasses is integrated under high temperature and high pressure with, for example, a PVB (polyvinyl butyral resin) laminated glass interlayer film. PVB film is firmly bonded to the glass. It can resist penetration, has good safety, blocks ultraviolet rays and reduces noise. It is an excellent safety glass. [0003] However, generally used laminated glass has a problem of being poor in heat insulation, although it is excellent in safety. Thereby various preparation methods of heat insulating laminated glass arise at the historic momen...
