Multilayer laminated material having at least one glass layer

摘要

A multilayer laminated material which comprises at least one layer of glass and which has improved thermal stability is distinguished in that it comprises a lower substrate layer of a plastic, a metal or a combination of plastic and metal, an intermediate layer arranged thereon and comprising a soft material or comprising a thermoplastic, a further fibrous intermediate layer comprising plastic, which is provided with a solvent-free adhesive material, and a top layer of glass. The multilayer laminated material is suitable for the installation of glass elements in the area of the electrical, the electronics and the automotive industry and for other industrial applications.

1. A multilayer laminated material comprising:
(a) a top layer of glass, wherein the top layer of glass forms a first outer layer; (b) a fibrous intermediate layer of thermoplastic polymer arranged in contact with the top layer of glass, wherein the fibrous intermediate layer comprises a solvent-free adhesive material which is liquid under the action of heat but normally solid; (c) an intermediate layer comprising an elastomer which, wherein the elastomer comprises a mix of:
(i) about 5 to 25% by weight, based on total weight of the mix, of a crystalline fraction, wherein the crystalline fraction comprises a polypropylene homopolymer or a copolymer of propylene wherein the copolymer comprises at least 85 wt. %, based upon the total weight of the copolymer, of propylene derived units and no more than 15 wt. %, based upon the total weight of the copolymer, of units derived from a linear or branched olefin having 2 or 4 to 10 carbon atoms; and(ii) about 75 to 92% by weight, based on total weight of the mix, of an elastomeric fraction,wherein the elastomeric fraction comprises a copolymer of ethylene with propylene or a CH2═CHR α-olefin, where R is a C2-C8 alkyl radical, and optionally minor quantities of a diene, or a copolymer of ethylene with propylene and said α-olefin, and optionally minor quantities of a diene, andwherein the elastomer has rubber-elastic properties at room temperature and has a glass transition temperature Tg of lower than 0° C. and a flexural modulus lower than 60 MPa; and (d) a lower substrate layer of a plastic, a metal or a combination of plastic and metal, wherein the intermediate layer is arranged on top of the lower substrate.
