Film Laminate and Interior Trim Part for Motor Vehicles

Abstract

The invention relates to a film laminate ( 1 ), comprising at least one compact decorative layer ( 2 ) with a lacquer layer ( 3 ) on the upper side and with a foam layer ( 4 ) on the underside, where the density of the foam layer ( 4 ) is more than 500 kg/m 3 . The invention further relates to the use of said film laminate ( 1 ) for the coating of components for the interior trim of motor vehicles and to interior trim parts of motor vehicles provided with said film laminate ( 1 ). The foam layer ( 4 ) of thermoformable film laminates ( 1 ) for the coating of interior trim parts for a motor vehicle in the region of the airbag covers and/or in the region of the tear seams of the airbag covers, where these have no lines of weakness, is based on a composition which comprises a) from 15 to 60 parts by weight of at least one thermoplastic vulcanizate (TPV) b) from 15 to 35 parts by weight of at least one high melt strength polyolefin (HMS polyolefin) and c) from 30 to 60 parts by weight of at least one low density polyethylene (LDPE), where the proportions of a), b) and c) give a total of 100.

1 .- 10 . (canceled) 
     
     
         11 . A film laminate comprising at least one compact decorative layer comprising a lacquer layer on an upper side of the at least one compact decorative layer, and a foam layer on an underside of the at least one compact decorative layer, wherein the density of the foam layer is greater than 500 kg/m 3 , and wherein the foam layer is based on a polymer composition comprising:
 a) from 15 to 60 parts by weight of at least one thermoplastic vulcanizate (TPV);   b) from 15 to 35 parts by weight of at least one high melt strength polyolefin (HMS polyolefin); and,   c) from 30 to 60 parts by weight of at least one low density polyethylene (LDPE);   
       and, 
       wherein proportions of a), b) and c) are a total of 100. 
     
     
         12 . The film laminate as claimed in  claim 11  wherein the foam layer is based on a polymer composition comprising:
 a) from 35 to 45 parts by weight of the at least one thermoplastic vulcanizate (TPV); 
 b) from 15 to 25 parts by weight of the at least one high melt strength polyolefin (HMS polyolefin); and, 
 c) from 35 to 45 parts by weight of the at least one low density polyethylene (LDPE); 
 
       wherein proportions of a), b) and c) are a total of 100. 
     
     
         13 . The film laminate as claimed in  claim 11 , wherein the at least one high melt strength polyolefin is a high melt strength polypropylene. 
     
     
         14 . The film laminate as claimed in  claim 11 , wherein the at least one thermoplastic vulcanizate is based on polypropylene and ethylene-propylene-diene elastomer (EPDM). 
     
     
         15 . The film laminate as claimed in  claim 11 , wherein the foam layer is based on a polymer composition which comprises a solid chemical blowing agent. 
     
     
         16 . The film laminate as claimed in  claim 11 , wherein the foam layer has been physically foamed. 
     
     
         17 . The film laminate as claimed in  claim 11 , wherein the lacquer layer has a thickness less than 10 μm, wherein the compact decorative layer has a thickness from 0.2 to 0.7 mm, and wherein the foam layer has a thickness from 0.5 to 2.0 mm. 
     
     
         18 . The use of a film laminate as claimed in  claim 11  for the coating of components for the interior trim of motor vehicles, in particular at least in the region of the airbag covers or in the region of the tear seams of the airbag covers. 
     
     
         19 . An interior trim part for motor vehicles, preferably dashboard, provided with a film laminate as claimed in claim  1 . 
     
     
         20 . The interior trim part as claimed in  claim 19 , where the film laminate is arranged at least in a region of an airbag cover and/or in a region of tear seams of the airbag cover.
