Abstract

The invention relates to a composite moisturizing and curing film with effects of adhering prevention and easy stripping. The composite moisturizing and curing film consists of an outer plastic thin film layer, a water absorbing mixing layer and a composite material layer, wherein the water absorbing mixing layer is arranged at the inner side of the outer plastic thin film layer, and is made of water absorbing material and an adhesive; the composite material layer is arranged at the inner side of the water absorbing mixing layer, and is formed by hotly pressing a thin film and a nonwoven cloth. The composite moisturizing and care film has the advantages that the adhesion is prevented, the stripping is easy, the moisturizing and curing effects are good, the strength is high, and the construction speed is high.

Description

technical field

[0001] The invention relates to the technical field of moisturizing and curing films, in particular to a composite moisturizing and curing film that is anti-adhesive and easy to release. Background technique

[0002] The inner side of the existing concrete moisturizing and curing film is a hairy non-woven fabric. After the moisturizing and curing film is attached to the concrete surface to complete the curing, the non-woven fabric and the rough concrete surface penetrate into one body, which is not easy to tear off. The strength of the woven fabric is low, and it is easily broken during the tearing process after completion, forming mottled debris on the surface of the concrete wall, which seriously affects the appearance and quality of the concrete project. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a composite moisturizing and curing film that is anti-adhesive and eas...

Examples

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...
