Abstract
The invention relates to a thermal and/or acoustic insulation product based on mineral fibers for use above 150° C., especially between 200 and 500° C., or even up to 700° C. and higher in the case of rock fibers, which comprises at least 1%, or at least 2% and even more than 4% by weight of binder obtained from a sizing composition, the resin or resin mixture of which consists substantially of at least one epoxy-type resin whose EEW value is between 150 and 2000, preferably at least 160 and/or at most 700, or even at least 170 and/or at most 300.
Claims14
A thermal and/or acoustic insulation product, comprising mineral wool and at least 1%, by weight, of a cured organic resin, and further comprising a web of mineral fibers, the grammage of which, is between 10 and 300 g/m2, and wherein said web is placed on at least one of the outer surfaces of said insulating product, and wherein said web comprises at least 1%, by weight, of a binder, obtained from a sizing composition, and wherein said composition comprises a resin or resin mixture, comprising at least one epoxy resin, whose EEW value is between 150 and 2000;
- and wherein said product releases less than 50 mg/kg (of product) of formaldehyde, and less than 50 mg/kg (of product) of methyl isocyanate (MIC), when it is heated to 350° C. for at least 15 minutes, and wherein the product can be used at temperatures above 150° C.
A thermal and/or acoustic insulation product, comprising mineral wool and comprising at least 1%, by weight, of a binder, obtained from a sizing composition, and wherein said composition comprises a resin or resin mixture, comprising at least one epoxy resin, whose EEW value is between 150 and 2000, and
- wherein said product further comprises a web of mineral fibers, the grammage of which is between 10 and 300 g/m2, and wherein said web is placed on at least one of the outer surfaces of said insulating product, and wherein said web comprises at least 1%, by weight, of a binder, obtained from a sizing composition, and wherein said composition comprises a resin or resin mixture, comprising at least one epoxy resin, whose EEW value is between 150 and 2000.
