Problems solved by technology

However, high polymer stiffness results in poor acoustic damping and sound barrier performance compared to softer polymer interlayers
Of course, softer polymers cannot perform to the same level as ionomers in hurricane glazing, so there is a need to develop interlayer products that achieve good hurricane resistance and high acoustic barrier performance
[0006] Certain ionomer-based multilayer interlayers with improved acoustic properties have generally been disclosed in the literature (see, e.g., previously incorporated US7297407B2, US2015 / 0158986A1, US2016 / 0167348A1, US2017 / 0320297A1, US2018 / 0117883A1, WO2016 / 076336A1, WO2016 / 076337A1, WO2016 / 076338A1 WO2016 / 076339A1 and WO2016 / 076340A1), but exemplary interlayers do not have a sufficient combination of properties for hurricane resistant laminated glazing

preparation example Construction

[0206] Regarding the production method of laminated glass, for example, in the case of using a nip roll, a method is exemplified in which after the first provisional contact bonding is performed at the flow start temperature of the skin resin or lower, after the near flow Temporary contact bonding is further carried out at the starting temperature. Specifically, for example, a method is exemplified in which the component is heated at a temperature of about 30°C or higher and about 100°C or lower by an infrared heater or the like, then degassed by a roll, and further heated at about 50°C or more Heating at a temperature of about 150° C. or less, followed by contact bonding by rollers to achieve bonding or temporary bonding.

[0207] In addition, laminated glass can also be produced by aggregating and laminating glass coated with layer B on both surfaces of layer A such that the composition of the laminated material of the present invention is included inside the laminated glass. ...

specific Embodiment approach

[0214] A particular embodiment of the invention is a multilayer interlayer which, when laminated between two panes of glass each 6 mm thick to produce a laminate, has a combination of: a) sound transmission Class (STC) of 40 or greater (as determined according to ASTM E90-2016 and ASTM E413-2010 described above), b) and laminate haze of less than about 0.6 (as determined according to ASTM D1003 described above -61 (determined by method A), c) hurricane large projectile (Class D) resistance to shock and positive pressure cycling to 6.22 kPa according to ASTME1996-2017 as described above, and d) by modulating the transmission of solar infrared radiation Sun barrier protection.

Abstract

Provided herein are multilayer polymeric interlayers comprising ionomers and acoustic damping compositions, and glass laminates made from them, which provide an improved combination of hurricane resistance, acoustic damping properties and, optionally, solar barrier performance.

Description

technical field [0001] The present invention generally relates to multilayer interlayers and glass laminates containing such interlayers. More specifically, the present invention relates to a multilayer interlayer comprising at least one ionomer layer, at least one sound-insulating interlayer and optionally having solar heat shielding properties, wherein a glass laminate comprising such an interlayer has acoustic damping and associated desired combination of acoustic barrier properties, flexural strength, bending stiffness and optical properties, and optionally solar heat shielding properties, which enable protection from windborne debris and hurricane force winds. Background technique [0002] Laminated glass is commonly used in window panes etc. for construction and transportation related end uses. It is usually made by laminating two sheets of glass to a polymer interlayer. A particular advantage of laminated glass over solid glass sheets is the improved impact and shat...
