Embodiment 1
[0018] Such as figure 1 As shown, on the surface of the cement concrete 5, a kind of anti-bonding and easy-release composite moisture-retention curing film is pasted, and the composite moisture-retention curing film for anti-bonding and easy-release is composed of an outer plastic film layer 11, a water-absorbing mixing layer 2, a composite The outer plastic film layer 11 is provided with a water-absorbing mixed layer 2 inside, and the inner side of the water-absorbed mixed layer 2 is provided with a composite material layer 3 .
[0019] The water-absorbing mixed layer 2 is composed of water-absorbing material 6 and viscous glue 7 . The water-absorbing material 6 can be graft copolymerized products of natural polymers such as starch and cellulose, or polymerized products such as sodium acrylate and methyl methacrylate. The polymer water-absorbing material 6 has super-strong water-absorbing and moisturizing properties, can absorb water hundreds to a thousand times its own weig...
Embodiment 2
[0022] Such as figure 2 As shown, on the surface of the cement concrete 5, a kind of anti-bonding and easy-release composite moisture-retention curing film is pasted, and the composite moisture-retention curing film for anti-bonding and easy-release is composed of an outer plastic film layer 11, a water-absorbing mixing layer 2, a composite The outer plastic film layer 11 is provided with a water-absorbing mixed layer 2 inside, and the inner side of the water-absorbed mixed layer 2 is provided with a composite material layer 3 .
[0023] The water-absorbing mixing layer 2 consists only of water-absorbing material 6 . The water-absorbing material 6 can be graft copolymerized products of natural polymers such as starch and cellulose, or polymerized products such as sodium acrylate and methyl methacrylate. The composite material layer 3 is composed of a multi-layer film 8 and a multi-layer non-woven fabric 9 by fusing, sewing, hot pressing, or gluing. The outer plastic film la...
