Description

A kind of composite punched membrane

Technical field

The utility model belongs to articles for daily use technical field more particularly to a kind of composite punched membrane.It is defended more particularly to women Raw towel, panty liner, adult lose a kind of the answering with absorption human body discharge liquor used in the amenities such as flap trousers, baby diaper Making hole film (also known as " composite sanitary upper material ") is closed, which has PE making hole films and PE perforating film layers two to be combined.It is special It is not related to the production method of this two layers of composite punched membrane.

Background technology

Currently, the prior art commonly used in the trade is such：

Composite punched membrane (also known as " sanitary upper material ") loses flap trousers, baby diaper as sanltary towel, panty liner, adult The basic fabric of equal amenities largely uses in the absorbent commodities such as previous sanitary napkin, disposable diaper, diaper.This face Material is generally combined by PE perforating film layers and PE perforating film layers, has rapid osmotic rate and diffusivity to liquid.

Chinese patent disclosed on 07 20th, 2,005 one it is entitled《The production technology of composite sanitary upper material》, application Day is on 09 29th, 2001.The production method of its composite sanitary upper material recorded is as follows：First by PE raw material agitating and heatings, plus The PE films that heat is crossed carry out vacuum sucking holes on dedicated cylinder mould, then the PE making hole films produced carry out two layers it is compound, this The composite sanitary upper material that sample is produced has three-dimensional sense, quick permeation, good permeability and dry and comfortable.

In conclusion problem of the existing technology is：

(1) since the secondary punching of former PE making hole films single layer is harder, not soft enough.

(2) it is changed to two layers of compound secondary punching now, the deficiency before three-dimensional but also pro-skin softness can solve not only.

Solve the difficulty and meaning of above-mentioned technical problem：

The present invention is made that a kind of two layers of PE film is compound from the angle of industrialization large-scale production and public demand and secondary beats The production technology in hole, the flexibility of product is good and rapid osmotic the purpose is to improving, and dry-ness good, gas permeability is strong and continuous sense parent The fine quality of skin.

Invention content

In view of the problems of the existing technology, the utility model provides a kind of composite punched membrane.The face of the utility model Material is combined by PE perforating film layers and PE perforating film layers, has rapid osmotic rate and diffusivity to liquid.

The utility model is realized in this way a kind of composite punched membrane, the composite punched membrane is provided with PE raw material layers；Institute State the front micropore face of the compound PE making hole films in PE raw material layers upper layer；The reverse side micropore of the compound PE making hole films of PE raw material layers lower layer Face.

Further, the composite punched membrane is concaveconvex shape.

The advantages of the utility model and good effect are：

The utility model avoids the chemical contamination that adhesive material brings health product.This raw materials technology uses excellent Be made PE making hole films and PE making hole films of material carries out compound, the three-dimensional sense with height continuous sense pro-skin and human skin again Contact, dryer and comfortableer, flexible touch more preferably, ooze human body fluid function while also having effects that reverse-osmosis-prevention by the existing speed of lower layer's making hole film.It can It prevents from leading to the senses of discomfort such as allergy, itch under by the effect of wet and body temperature.Compared with prior art, reality outstanding is had more Matter feature and significant progress.

The utility model is produced by the production of PE making hole films and secondary composite sanitary upper material, is needed to heat twice, be risen in this way Existing sterilization, and the effect of antibacterial are arrived.

The utility model uses secondary punching board, compound by high temperature two layers of PE making hole film of progress, not only makes two layers of PE Film bonds reliably, and is bonded uniformly, not wrinkled.

Fig. 2 is the composite punched membrane explosive view that the utility model embodiment provides.

In figure：1, PE raw material layers；2, compound PE making hole films；3, front micropore face；4, reverse side micropore face.

Specific implementation mode

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain this practicality It is novel, it is not used to limit the utility model.

The utility model is made that a kind of two layers of PE film compound two from the angle of industrialization large-scale production and public demand The production technology of secondary punching, the purpose is to improve, the flexibility of product is good and rapid osmotic, dry-ness good, gas permeability are by force and continuous Feel the fine quality of pro-skin.

As depicted in figs. 1 and 2, the composite punched membrane that the utility model embodiment provides, is provided with PE raw material layers 1；It is described The front micropore face 3 of the compound PE making hole films in PE raw material layers upper layer 2；The reverse side of the compound PE making hole films of 1 lower layer of PE raw material layers 2 Micropore face 4.

The composite punched membrane is concaveconvex shape.

The utility model is further described with reference to principle.

The production method for the composite punched membrane that the utility model embodiment provides, with good PE raw materials, color masterbatch, hydrophilic agent Raw material as hydrophobic layer making hole film；Including：

It is uniform by blender heating stirring by PE raw materials and color masterbatch, hydrophilic agent, then be cast out by the heating of extrusion board Come；Heated PE raw materials are carried out vacuum sucking holes postcooling and wind unloading and being bundled on dedicated pore cylinder mould by being cast board Product.

Then the PE making hole films produced using reverse side micropore carry out two layers it is compound, using secondary punching board PE Making hole film heats splitting winding after punching cools down by male and female mold and completes, and sanitary upper material more has permeability fast, ventilative Property is strong, dry-ness good.

The composite sanitary upper material of production has hydrophobic layer, and hydrophobic layer is equipped with equal reverse of the cloth micropore, and the program uses It carries out vacuum sucking holes on cylinder mould, and is carried out with PE making hole films with PE making hole films compound, achieve good effect.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model Protection domain within.
