Abstract
The present invention relates to a method for manufacturing insulation products based on mineral wool bound by an organic binder, comprising the following successive steps: (a) providing a mineral wool, (b) humidifying the mineral wool, (c) placing the humidified mineral wool fibers in contact with particles of binder comprising a mixture of thermosetting reagents, (d) shaping the mixture of mineral wool and binder particles, and (e) heating the shaped mixture to a temperature and for a period sufficient to allow the condensation of the reagents and the formation of an insulation product based on mineral wool bound by an insoluble and infusible organic binder.
Claims20
A method for manufacturing an insulation product comprising mineral wool bound by an organic binder, comprising the following successive steps:
- (a) humidifying a mineral wool to provide a humidified mineral wool that comprises from 0.2 to 1.5% by weight of water;
- (b) placing the humidified mineral wool that comprises from 0.2 to 1.5% by weight of water in contact with particles of binder comprising a mixture of thermosetting reagents to provide a mixture of mineral wool and binder particles;
- (c) shaping the mixture of mineral wool and binder particles to provide a shaped mixture;
- and
- (d) heating the shaped mixture to a temperature and for a period sufficient to allow condensation of the reagents and the formation of the insulation product comprising mineral wool bound by the organic binder.
