Abstract
An insulation product comprising fibers consolidated with a binder is disclosed to which a non-aqueous moisturizer has been included. The binder is disposed upon the fibers and the non-aqueous moisturizer is in contact with fibers and/or binder. The insulation product may be an uncured fiber insulation product in which the binder is an uncured binder. The insulation product may be packaged in a suitable material. Accordingly, disclosed is a packaged uncured fiber insulation product.
Claims18
A packaged uncured fiber insulation product comprising:
- an uncured binder composition,
- a collection of fibers, and
- a non-aqueous moisturizer, wherein
- (i) the uncured binder composition is in contact with the collection of fibers consolidating the collection of fibers,
- (ii) the non-aqueous moisturizer is in contact with the uncured binder composition,
- (iii) the uncured binder composition in contact with the collection of fibers is packaged in a suitable packaging material, and
- (iv) the non-aqueous moisturizer provides a lower adhesive force between the uncured binder composition and the suitable packaging material compared to a comparable product without the non-aqueous moisturizer.
6-9. (canceled)
A fiber insulation product comprising:
- an uncured binder composition,
- a collection of fibers, and
- a non-aqueous moisturizer, wherein
- (i) the uncured binder composition is oriented as a layer at least partially encompassing the collection of fibers, and
- (ii) at least a portion of the non-aqueous moisturizer is oriented as an outer layer on an exterior surface of the layer of the uncured binder composition.
17-21. (canceled)
A method of manufacturing an uncured insulation product comprising the following steps:
- mixing a carbohydrate, an ammonium salt of a multiprotic acid, and a silane in an aqueous solution to form a binder solution,
- contacting glass fibers with the binder solution,
- contacting the glass fibers with a non-aqueous moisturizer, and
- volatilizing water from the binder solution to form an uncured binder composition in contact with the glass fibers.
