Description
Technical Field
The utility model relates to a polypropylene film field, concretely relates to synthetic paper for thermal insulation of convenient printing and complex.
Background
The polypropylene film is one of important flexible packaging materials, has the advantages of no color, no odor and no toxicity, and is widely applied to the fields of book printing, composite bag making, product packaging and the like.
At present, the traditional polypropylene film is limited by a processing technology, the density of the film is high and is about 0.8-1.0 g/cm3, so the manufacturing cost is high, meanwhile, because the polypropylene film belongs to a non-polar crystalline material, the surface adhesiveness of the film is poor, so that the printing and the compounding with other films on the surface of the polypropylene film are difficult, and the surface of the film needs to be activated by surface treatment (such as corona and the like) before printing or compounding with other films, so the ink adhesiveness and the bonding performance with other films are enhanced, the cost is further increased undoubtedly, and the application development of the polypropylene film is limited.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem in the above-mentioned background art and providing a convenient printing and compound synthetic paper for thermal insulation, this synthetic paper adopts polypropylene film combined material preparation, and density is low, effective reduction in production cost, and surface activity is high simultaneously, can directly print and compound not through handling, labour saving and time saving, and it is very convenient to use, and the practicality is good, and the details are explained below.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a conveniently printed and compounded synthetic paper for thermal insulation, which comprises a foamed polypropylene layer, wherein one side of the foamed polypropylene layer is provided with an antibacterial layer, the other side of the foamed polypropylene layer is provided with a hydrophilic layer, and the other side of the hydrophilic layer is provided with a hydrophobic layer;
the hydrophilic layer is absorbed with strong oxidant solution.
As an important design of the scheme, the antibacterial layer is an antibacterial BOPP film.
As the optimized design of the scheme, the hydrophilic layer is made of a hydrophilic film material, and the hydrophilic film material comprises a polypropylene hollow fiber membrane and a modified membrane.
As the optimized design of the scheme, the hydrophobic layer is made of a hydrophobic film material, and the hydrophobic film material comprises polyethylene, polypropylene, polyvinylidene fluoride and polysulfone.
Has the advantages that: synthetic paper for thermal isolation adopt polypropylene film combined material preparation, density is low, effective reduction in production cost, film surface activity is high simultaneously, can directly print and compound not through handling, labour saving and time saving, it is very convenient to use, has strengthened polypropylene film's application and development greatly, the practicality is good.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
The reference numerals are explained below:
1. a hydrophobic layer; 2. a hydrophilic layer; 3. a foamed polypropylene layer; 4. and (4) an antibacterial layer.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, the utility model provides a pair of make things convenient for printing and compound synthetic paper for thermal insulation, including foaming polypropylene layer 3, foaming polypropylene layer 3 is compared antiseized polypropylene layer density and is lower, uses foaming polypropylene layer 3 to make the basic unit of synthetic paper for thermal insulation can fully reduce the density of synthetic paper, reduces its manufacturing cost then.
As shown in fig. 1, if the synthetic paper for thermal insulation of the present application is used for packaging food and medicine, an antibacterial layer 4 should be disposed on one side of the foamed polypropylene layer 3, and an antibacterial BOPP film is used as the antibacterial layer 4.
If the synthetic paper for thermal insulation of the present application is not used in the above-mentioned fields of food and medicine, one side of the foamed polypropylene layer may not be provided with the antibacterial layer 4, for example, one side of the foamed polypropylene layer may be directly in contact with the packaged article, which contributes to the reduction of the density of the synthetic paper.
As shown in fig. 1, a hydrophilic layer 2 is disposed on the other side of the foamed polypropylene layer 3, the hydrophilic layer 2 is made of a hydrophilic film material, such as a polypropylene hollow fiber membrane, a modified membrane, and the like, the hydrophilic layer 2 can absorb a certain amount of aqueous solution, such as a strong oxidant solution, so that after the hydrophilic layer 2 is attached to the other side of the foamed polypropylene layer 3, the strong oxidant solution contacts the surface of the other side of the foamed polypropylene layer 3, the strong oxidant solution cleans lipid substances such as wax substances on the surface of the foamed polypropylene layer 3 and introduces polar groups, so that surface molecular chains of the foamed polypropylene layer 3 are oxidized, broken and formed into micropores, thereby increasing roughness of the surface of the foamed polypropylene layer 3, improving surface activity of the foamed polypropylene layer 3, and facilitating surface printing of the foamed polypropylene layer 3 or compounding with other films.
Hydrophilic layer 2 keeps the laminating at ordinary times with foaming polypropylene layer 3, when needs print or compound with other films on synthetic paper for thermal isolation, with hydrophilic layer 2 tear, dry foaming polypropylene layer 3 the surface can, easy operation is convenient, need not additionally to handle synthetic paper surface for thermal isolation, labour saving and time saving, the cost is with low costs, has strengthened the application and the development of polypropylene film greatly, the practicality is good.
In order to prevent the strong oxidant solution from volatilizing, the other side of the hydrophilic layer 2 should be provided with a hydrophobic layer 1, and the hydrophobic layer 1 is made of a hydrophobic film material, such as polyethylene, polypropylene, polyvinylidene fluoride, polysulfone, and the like.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
