Concrete cure blanket having reflective bubble layer and method of manufacturing
First Claim
1. A method for manufacturing a lightweight multilayer heat reflective concrete cure blanket, comprising:
- a. forming a first flexible structure having a first outer peripheral edge and comprising a first moisture-impervious outer film and a first flexible undulating film;
b. heat sealing the first flexible undulating film to the first moisture-impervious outer film to form a plurality of first air-filled insulative pockets and a plurality of first open spaces between the first air-filled pockets;
c. forming a second flexible structure having a second outer peripheral edge and comprising a second moisture-impervious outer film and a second flexible undulating film;
d. heat sealing the second flexible undulating film to the second moisture-impervious outer film forming a plurality of second air-filled insulative pockets and a plurality of second open spaces between the second air-filled insulative pockets, wherein the second moisture-impervious outer film includes a plurality of heat reflective elements dispersed throughout the second moisture-impervious outer film; and
e. sealing the first flexible structure to the second flexible structure about the first and second outer peripheral edges to include a moisture-impervious chamber space formed between the first air-filled insulative pockets and the second air-filled insulative pockets, facing the first open spaces to the second air-filled pockets and facing the second open spaces to the first air-filled pockets, overlapping the first air-filled pockets with the second air-filled pockets to form a gap between first air-filled pockets and the second air-filled pockets as to communicate in a heat transfer path therebetween, and forming a flexible heat reflective concrete cure blanket.

Abstract
A method of manufacturing a lightweight multilayer heat reflective concrete cure blanket having a moisture-impervious top outer layer, a moisture-impervious bottom outer layer, and the top and bottom layers sealingly connected to each other at the boundaries of the layers to form a moisture-impervious chamber between the first and second layers. The chamber includes at least one bubble type insulative layer therein, and the bottom surface of the blanket comprises a heat reflective material to reflect heat emanating from the concrete when the blanket is placed over the concrete. In a further embodiment, heat reflective material is applied to at least one inner bubble type layer to reflect additional heat which radiates from the concrete through the insulative layer and back towards the concrete.

7. A method of manufacturing a lightweight multilayer heat reflective concrete cure blanket, comprising the steps of:
-
a. forming a first flexible structure having a first unslitted moisture-impervious outer film and a first flexible undulating film by heat sealing the first flexible undulating film to the first unslitted moisture-impervious outer film to form a first bubble-type insulative layer; b. forming a second flexible structure having a second unslitted moisture-impervious outer film and a second flexible undulating film by heat sealing the second flexible undulating film to the second unslitted moisture-impervious outer film to form a second bubble-type insulative layer, and applying a reflective material to the second unslitted moisture-impervious outer film as to reflect heat away from the second flexible structure; c. forming the first bubble-type layer having a plurality of first insulative pockets and a plurality of first open spaces between the first insulative pockets, and forming the second bubble-type layer having a plurality of second insulative pockets and a plurality of second open spaces between the second insulative pockets, wherein the first and second insulative pockets alternately face the second and first open spaces, respectively, to form a chamber space between the first and second insulative pockets; and d. sealing, in a moisture impervious manner, the first flexible structure to the second flexible structure about the first and second outer peripheral edges, maintaining a gap between the overlapping first insulative pockets and the second insulative pockets as to communicate in a heat transfer path to form a flexible heat reflective concrete cure blanket. - View Dependent Claims (8, 9, 10, 11)
