Description

Laminated coated glass with same color on front and back sides and preparation method thereof
Technical Field
The invention relates to the technical field of coated glass, in particular to laminated coated glass with the same color on the front and back sides and a preparation method thereof.
Background
The coated glass has good heat insulation performance, excellent energy-saving performance and excellent optical performance. Because the interlayer of the laminated glass is a tough transparent flexible material, when the laminated glass is impacted and broken, the fragments still firmly adhere to the interlayer, thereby improving the safety performance of the glass. With the current pursuit of safety and comfort performance, the application of the sandwich coating product is more and more.
The main body part of the building is usually designed as interlayer coated hollow glass, and the shutters of the refuge layer of the building curtain wall or the partition of the house are usually designed as glass with the same color in the positive and negative directions due to the factors of installation and appearance effect, and the color of the glass is coordinated with the color of the interlayer coated hollow glass of the main body part.
At present, the production of the shutter glass is mainly carried out by the colored PVB, but the cost of the colored PVB is high and is about 5 times of the cost of the common PVB, and the energy-saving performance of the prepared laminated glass is poor. The production of the laminated shutter glass is also carried out by adjusting the color of the colored glaze, but the production of the colored glaze glass has the harm of environmental pollution, and the color difference between the colored glaze surface and the non-colored glaze surface is large and cannot be matched and coordinated with the main body part.
