Description
Technical Field
The utility model belongs to the technical field of medical material and specifically relates to a high tenacity complex film.
Background
Along with the development of society, the usage of medical film is also more and more extensive, and the single performance of traditional film can not satisfy the requirement of modern apparatus at all, moreover because the problem of its material, for example can produce static, and is not corrosion-resistant, can produce and can cause very big medical accident, so need very big improvement, the utility model provides a complex film can be used for making gauze mask, operation protective clothing, medical sheet etc. combines the characteristic of multiple film, its whole performance of super high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high tenacity complex film of simple structure, soft texture, waterproof high resistance.
In order to achieve the above purpose, the technical scheme of the utility model:
the high-toughness composite film comprises a breathable film and a thin film, wherein the gram weight of the breathable film is 4 grams per square meter, the gram weight of the thin film is 15 grams per square meter, and the breathable film and the thin film are compositely bonded by adopting a hot melt adhesive.
Preferably, the cross section of the breathable film is in a network structure.
Preferably, the thickness ratio of the breathable film to the film is 1: 1.7.
the utility model discloses a beneficial condition lies in: the utility model adopts the above technical scheme provide a high tenacity complex film, its characteristics: simple structure, soft texture, waterproof high resistance.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a film; 2. and (3) a breathable film.
Detailed Description
As shown in fig. 1, the high-toughness composite film comprises a breathable film 2 and a film 1, wherein the gram weight of the breathable film 2 is 4 grams per square meter, the gram weight of the film 1 is 15 grams per square meter, the breathable film 2 and the film 1 are compositely bonded by using a hot melt adhesive, the cross section of the breathable film 2 is in a network structure, and the thickness ratio of the breathable film 2 to the film 1 is 1: 1.7.
in actual use, the breathable film 2 and the film 1 are compounded and bonded by hot melt adhesive, so that the bonding degree between the breathable film 2 and the film 1 is higher, the cross section of the breathable film 2 is of a network structure, and the net-shaped design can increase air circulation, effectively dissipate heat and balance the air pressure of an inner space and an outer space; the gram weight of the breathable film 2 is 4 grams per square meter, the gram weight of the film 1 is 15 grams per square meter, and the thickness ratio of the breathable film 2 to the film 1 is 1: 1.7, the composite membrane prepared by the proportion has strong toughness and is very suitable for preparing medical products.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to illustrate the principles of the invention, but rather that various changes and modifications may be made without departing from the spirit and scope of the invention, which shall fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
