Problems solved by technology

Unfortunately, however, plastic glazing has a higher permeability to infrared radiation compared to glass glazing, which ultimately leads to increased heating of interior spaces such as those of buildings and vehicles
Increased interior space temperature reduces passenger or resident comfort and may cause increased demand for air conditioning, which in turn increases energy consumption

Embodiment 1- Embodiment 13

[0070] Example 1-Example 13: Preparation of infrared blocking layer

[0071] Five infrared blocking compositions were prepared by mixing a polymer solution of UVHC5000 (commercially available from Momentive Co.) containing 45 wt% solids with a 20 wt% CTO dispersion. The IR blocking composition was bar coated onto a 0.5mm thick polycarbonate sheet, heated at 80 degrees Celsius (°C) for 30 minutes, and under ambient conditions using a Fusion UV model F300S-6 processor using H lamp, 300W / in, UV curing at 5m / min. The polycarbonate sheet had a haze of 0.1%, a visible light transmission of 90%, and a total solar energy transmission of 86%.

[0072] Adhesion, haze, total solar energy transmittance, and visible light transmittance of the infrared blocking layers of Example 2, Example 3, and Example 5 were measured and shown in Table 1. The transmission (dotted line) and reflection (solid line) spectral data of the infrared blocking layer of Example 5 in the visible IR range were me...

Embodiment 14- Embodiment 16

[0079] Example 14-Example 16: Effect of polymer matrix

[0080] Three infrared blocking layers were prepared using the same coating method as in Example 1-Example 5, except that the curable prepolymer was changed. The curable prepolymer of Example 14 is UV curable silicone based coating UVHC5000, the curable prepolymer of Example 15 is heat curable acrylate D1457, and the curable prepolymer of Example 16 is UV curable Acrylate DM353L, all commercially available from Momentive. Example 14 and Example 16 included the solvent propylene glycol monomethyl ether (PGME).

[0081]

[0082] Table 3 shows that Example 14 has a significantly lower haze of only 4.9% compared to the haze of Examples 15 and 16 at the same CTO loading.

[0083] Embodiments of compositions, layers formed therefrom, layered structures comprising layers, and methods of formation of the present invention are listed below.

Embodiment approach 1

[0084] Embodiment 1: An infrared blocking composition, comprising: based on the total weight of the curable prepolymer and the infrared blocking agent, 60 to 95wt% or 60 to 98wt% of the curable prepolymer; based on the curable prepolymer The total weight of the substance and the infrared blocking agent, 2 to 40wt% or 5 to 40wt% of the infrared blocking agent; wherein the infrared blocking agent contains indium tin oxide, antimony tin oxide, tin oxyfluoride, tungsten oxide or contains the foregoing A combination of at least one of them.

Abstract

In an embodiment, an infrared blocking composition comprises 60 to 98 wt% of a curable prepolymer based on a total weight of the curable prepolymer and an infrared blocking agent; 2 to 40 wt% of the infrared blocking agent based on a total weight of the curable prepolymer and the infrared blocking agent; wherein the infrared blocking agent comprises indium tin oxide, antimony tin oxide, fluorine tin oxide, tungsten oxide, or a combination comprising at least one of the foregoing.

Description

[0001] References to related applications [0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 62 / 350,346, filed June 15, 2017. This related application is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to an infrared blocking composition, a method of forming the same, and an infrared layer formed therefrom. Background technique [0004] Plastic glazing has many advantages over traditional glass glazings. These advantages include, for example, increased fracture resistance, reduced weight and, for use in vehicles, increased occupant safety in the event of a traffic accident and lower fuel consumption. Unfortunately, however, plastic glazing has a higher permeability to infrared radiation compared to glass glazing, which ultimately leads to increased heating of interior spaces, such as those of buildings and vehicles. Increases in interior space temperature reduce passenger...
