Embodiment 1

[0133] Preparation of first and second surface layers:

[0134] Add 40 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO) as a plasticizer to 100 parts by weight of polyvinyl butyral resin (PVB resin, 30 mol% of hydroxyl content), and mix The rollers were fully kneaded to prepare composition 1 for making the first and second surface layers.

[0135] The production of the middle layer:

[0136] Add 60 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO) as a plasticizer to 100 parts by weight of polyvinyl butyral resin (PVB resin, hydroxyl content 25 mol%), use a mixing The rollers were sufficiently kneaded to prepare a composition 2 for producing an intermediate layer.

[0137] Production of multilayer interlayer film:

[0138] The obtained compositions 1 and 2 were coextruded using an extruder to obtain a laminate in which an intermediate layer was laminated between the first and second surface layers. Next, the obtained laminate was stored in a hi...

[0142] The amount of hydroxyl groups of the PVB resin, the type and content of the plasticizer, the cross-sectional shape in the thickness direction, the maximum thickness and the minimum thickness, and the wedge angle θ are set as shown in Table 1 below. Similarly, a multilayer interlayer film and laminated glass were obtained.

[0144] Production of single-layer interlayer film:

[0145]Add 40 parts by weight of triethylene glycol di-2-ethylhexanoate (3GO) as a plasticizer to 100 parts by weight of polyvinyl butyral resin (PVB resin, 30 mol% of hydroxyl content), and mix After sufficient kneading by the rollers, extrusion molding is performed using an extruder to produce a molded body. A single-layer interlayer film (length 1000mm) was prepared by storing the obtained molded article in an environment with high temperature and high humidity or with local differences in temperature and humidity in an environment with high temperature and low humidity to locally change the moisture content. × horizontal 350mm). For this single-layer interlayer film, the thickness of one end in the longitudinal direction is thinner than the thickness of the other end opposite to the one end, and the thickness in the transverse direction is uniform, and the maximum thickness and minimum thickness of the interlayer film ar...

Abstract

Provided are an interlayer film for laminated glass, configured so that the interlayer film increases the penetration resistance of the entire area of the laminated glass when used in the laminated glass, and laminated glass using the interlayer film for laminated glass. An interlayer film (1) for laminated glass has one end (1a) having a thickness less than that of the other end (1b). The thin region of the interlayer film (1) for laminated glass has higher water content than the thick region thereof. Laminated glass (21) comprises a first laminated glass-forming member (22), a second laminated glass-forming member (23), and the interlayer film (1) for laminated glass, sandwiched between the first and second laminated glass-forming members (22, 23).

Description

technical field [0001] The present invention relates to an interlayer film for laminated glass that can be preferably used, for example, in a head-up display, and more specifically, to a laminated glass that can improve the puncture resistance of the entire area of ​​the laminated glass when used in a laminated glass An interlayer film and a laminated glass using the interlayer film for laminated glass. Background technique [0002] Even if the laminated glass is damaged by an external impact, the amount of scattered glass fragments is small, and it is excellent in safety. Therefore, the above-mentioned laminated glass is widely used in automobiles, railway vehicles, airplanes, ships, buildings, and the like. The above-mentioned laminated glass can be produced by interposing an interlayer film for laminated glass between a pair of glass plates. [0003] As the above-mentioned laminated glass for automobiles, a head-up display (HUD) is known. For HUD, the driving data of t...
