Problems solved by technology

[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 easy to break during the tearing process after completion, forming mottled fragments on the surface of the concrete wall, which seriously affects the appearance and quality of the concrete project

Embodiment 1

[0018] Such as figure 1 As shown, on the surface of the cement concrete 5, there is a composite moisture-retaining maintenance film pasted, and the composite moisture-retention maintenance film for anti-bonding and easy release is composed of an outer plastic film layer 11, a water-absorbing mixing layer 2, and a composite material layer 3. The inner side of the outer plastic film layer 11 is provided with a water-absorbing mixed layer 2 , 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 ...

Embodiment 2

[0022] Such as figure 2 As shown, on the surface of the cement concrete 5, there is a composite moisture-retaining maintenance film pasted, and the composite moisture-retention maintenance film for anti-bonding and easy release is composed of an outer plastic film layer 11, a water-absorbing mixing layer 2, and a composite material layer 3. The inner side of the outer plastic film layer 11 is provided with a water-absorbing mixed layer 2 , 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 pla...

Abstract

The invention relates to a compound moisturizing maintenance film which is composed of an outer plastic thin film layer, a water absorbing and mixing layer and a composite material layer, wherein thewater absorbing and mixing layer is arranged on the inner side of the outer plastic thin film layer and is composed of a water absorbing material and sticky glue, the composite material layer is arranged on the inner side of the water absorbing material, and the composite material layer is formed by hot pressing the film and a non-woven fabric. The compound moisturizing maintenance film has the advantages of being stick-preventative, easy to release, good in moisturizing and maintaining effect, high in strength and high in construction speed.

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. 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 object of the present invention is to provide a composite moisturizing and maintenance film in order to overcome the deficiencies of the prior art. [0004] The present invention is achieved through the fo...
