Problems solved by technology

[0005] Although CN101168476A and CN108911528A realized the blocking of ultraviolet and infrared rays by setting the metal layer in the glass, and reached a certain degree of heat insulation and UV insulation effect, the metal layer will also make the final product strongly shield electromagnetic waves. Equipment maintenance costs are high and implementation conditions are harsh

preparation example Construction

[0087] In the present invention, when the functional coating 30 in the laminated glass is located on the surface of the functional film 40, the preparation method of the laminated glass may include:

[0088] 1. Lay the functional film 40 on the curved glass plate, apply a functional coating on the surface of the functional film 40 away from the curved glass plate, and thermally cure to obtain a pre-formed functional film 40. The pre-formed functional film 40 has a second vertical radius of curvature;

[0089] 2. Laminate the preformed functional film with the inner glass plate 60 and the outer glass plate 10 having the first vertical radius of curvature in sequence to obtain a laminated glass.

Embodiment 1

[0100] Embodiment 1 provides a kind of laminated glass, and its preparation method comprises:

[0101] 1. Combine 10g chelating agent A, 70g silica sol C, 17g epoxy resin, 2g infrared absorber (Cs x WO 3 ) mixing, and after stirring evenly, the functional coating is obtained;

[0102] 2. Prepare a curved glass plate with a first vertical radius of curvature as the inner glass plate 60, and lay the functional film 40 on the curved glass plate (this curved glass plate is different from the inner glass plate 60, as in the following examples and comparative examples). ) on the convex surface of ), and then coating the functional coating on the first convex surface 41 of the functional film 40, and then thermally curing them together in an oven to obtain a preformed preformed coating with a second vertical radius of curvature coated with a functional coating The functional thin film 40 of 30, the thickness of the functional coating 30 is 3.2 μm. Wherein, the second vertical radi...

Embodiment 2

[0105] Embodiment 2 provides a kind of laminated glass, and its preparation method comprises:

[0106] 1. Mix 10g of chelating agent B, 70g of silica sol C, 17g of epoxy resin, and 2g of infrared absorber (Cs x WO 3 ) mixing, and after stirring evenly, the functional coating is obtained;

[0107] 2. Prepare a curved glass plate with a first vertical radius of curvature as the inner glass plate 60, lay the functional film 40 on the convex surface of the curved glass plate, and then coat the functional coating on the first convex surface 41 of the functional film 40, Then, they are thermally cured together in an oven to obtain a preformed functional film 40 having a second vertical radius of curvature and coated with a functional coating 30 with a thickness of 5.2 μm. Wherein, the second vertical radius of curvature is 75% of the first vertical radius of curvature.

[0108] 3. Take another curved glass plate with the first vertical radius of curvature as the outer glass plate...

Abstract

The invention provides laminated glass. The laminated glass comprises an outer glass plate, an inner glass plate, a functional coating and a functional film, the functional film is positioned between the outer glass plate and the inner glass plate; the functional coating is coated on the surface of the outer glass plate, the surface of the inner glass plate or the surface of the functional film; the functional coating is obtained by curing a functional coating, the raw material of the functional coating comprises an infrared ray absorber and / or an ultraviolet ray absorber, and the thickness of the functional coating is 3-20 [mu] m; the functional film comprises at least two layers of alternately laminated resin films, the thickness of the functional film is 50-200 microns, and the visible light transmittance of the functional film is greater than or equal to 70%. The laminated glass has excellent heat insulation performance, can effectively block more than 99% of ultraviolet rays, has good electromagnetic wave permeability, and meets the use requirements of vehicle window glass at different parts of a vehicle.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a laminated glass with low total solar transmittance. Background technique [0002] People pay more and more attention to the comfort of car driving. Under continuous sunlight, the ultraviolet, visible light, and infrared rays in the car will continue to increase the temperature inside the car and accelerate the aging of the parts in the car. Therefore, it is necessary to meet the glass transmittance. Under the required conditions, further reducing the transmission of light and increasing the reflection of light can further reduce the temperature rise in the car and the aging of parts, and at the same time prevent ultraviolet rays from causing damage to the retina and skin. [0003] CN101168476A discloses a bakeable and bendable low radiation coated glass, the visible light transmittance after forming the laminated insulating glass can reach more than 76%, and the sol...
