SELF-STICK INSULATION AND METHODS

摘要

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.

1. A method of making a self-adhesive insulation blanket comprising:
providing an elongated fibrous insulation blanket or board product, the fibrous insulation blanket or board product having:
a length;a width;a thickness; anda 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, 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 or board product to form a blanket roll.
