Abstract
According to one embodiment, a self-adhesive insulation product is provided. The self-adhesive insulation product includes an elongated fibrous insulation blanket having a length, a width, a thickness, and a first major surface and a second major surface which each extend for the length and width of the fibrous insulation blanket. The self-adhesive insulation product also includes a coating of an adhesive applied to the first major surface of the fibrous insulation blanket. The adhesive includes an emulsion of a polymer material and water with the water evaporated so that the adhesive forms a dry layer atop the first major surface. The adhesive is nonbondable or nonadherable to other objects when in the dry state and is bondable or adherable to other objects upon the subsequent application of water.
Claims18
A method of making a self-adhesive insulation blanket comprising:
- providing an elongated fibrous insulation blanket, the fibrous insulation blanket having:
- a length;
- a width;
- a thickness;
- and
- a first major surface and a second major surface which each extend for the length and width of the fibrous insulation blanket;
- applying an adhesive to the first major surface of the fibrous insulation blanket, the adhesive comprising an emulsion of a polymer material and water;
- passing the fibrous insulation blanket or board product through an oven so as to evaporate the water of the adhesive such that the adhesive forms a dry layer atop the first major surface, the adhesive forming a polymer matrix atop the first major surface and being nonadherable when in the dry state and re-adherable upon a subsequent application of water;
- and
- rolling the fibrous insulation blanket to form a blanket roll.
A method of making a self-adhesive insulation product comprising:
- providing a fibrous insulation blanket or board product, the fibrous insulation blanket or board product having:
- a length;
- a width;
- a thickness;
- a first major surface and a second major surface which each extend for the length and width of the fibrous insulation blanket or board product;
- and
- a facer coupled with a second major surface, the facer having a length and a width approximately equal to the fibrous insulation blanket or board product;
- applying an adhesive to the first major surface of the fibrous insulation blanket or board product, the adhesive comprising an emulsion of a polymer material and water;
- and
- passing the fibrous insulation blanket or board product and facer through an oven so as to evaporate the water of the adhesive applied to the flanges so that the adhesive forms a dry layer atop the first major surface, the adhesive being nonadherable when in the dry state and re-adherable upon an application of water.
A method of making an insulation product comprising:
- providing an elongated fibrous insulation blanket or board product, the fibrous insulation blanket or board product-having:
- a length;
- a width;
- a thickness;
- and
- a first major surface and a second major surface which each extend for the length and width of the fibrous insulation blanket or board product;
- applying an adhesive to the first major surface of the fibrous insulation blanket or board product so that, when dried, a weight of a dry layer of the adhesive is between 2 and 8 percent of the weight of the fibrous insulation blanket, the adhesive comprising an emulsion of a polymer material and water;
- and
- passing the fibrous insulation blanket or board product through an oven so as to evaporate the water of the adhesive and thereby form the dry layer of the adhesive atop the first major surface, the adhesive forming a polymer matrix atop the first major surface and being nonadherable when in the dry state and re-adherable upon a subsequent application of water.
