ACOUSTIC LAMINATED GLAZING, ACOUSTIC INTERLAYER AND METHOD FOR SELECTING THE INTERLAYER FOR OPTIMAL ACOUSTIC DAMPING |
| 摘要 |
<p>The invention concerns a laminated glazing (2) comprising a viscoelastic plastic interlayer (3) including at least two damping films (30, 31) each having a loss factor tan d higher than 0,6 and a shear modulus G' less than 2.10<SUP>7</SUP> Pa over two respective temperature ranges t<SUB>A</SUB> and t<SUB>B</SUB>. The invention is characterized in that the film which has at frequency 200 Hz the highest loss factor tan d over a given temperature range included in the temperature ranges t<SUB>A </SUB>or t<SUB>B</SUB>, has a shear modulus equivalent to G'<SUB>eq</SUB> less than the shear modulus (moduli) equivalent to the other film(s) with G' <SUB>eq</SUB> = G ' <SUP>e</SUP></p> |
