Abstract
The invention discloses a gas-permeable waterproof casting film material. The gas-permeable waterproof casting film material comprises, by weight, 26% of high pressure polyethylene, 35% of low pressure polyethylene, 17% of linear polyethylene, 10% of metallocene, 5% of polypropylene, and 7% of an additive; the additive comprises a color masterbatch and a plastic lubricant. The gas-permeable waterproof casting film material can be used for producing gas-permeable waterproof casting film conveniently via mixing at a certain ratio, heating melting, and gas-permeable waterproof film processing technology; the obtained gas-permeable waterproof casting film is light and soft, is high in tensile strength, is suitable to be taken as a sanitary towel back material, and is capable of improving comfortability of users.
Description
Technical field
The present invention relates to sanitary towel's waterproof material formulatory arts, particularly relate to a kind of air permeable waterproof casting films material.
Background technology
Sanitary towel is a kind of material to liquid tool absorbing power, belongs to women's special nursing product.The main material of sanitary towel is cotton like paper pulp and polymeric absorbent body, is used for absorbing feminine menstrual and carrys out the time of tide, from the menses that vagina flows out, in order to avoid medicated clothing of making dirty.
Body fluid absorption is carried out with direct body contact in the top layer of sanitary towel, and therefore the performance of skin-material directly affects the experience of user.Existing conventional sanitary napkin surface all can be designed to hydrating structure, so that women physiological period uses during sanitary towel, body fluid is absorbed fast, underwear is polluted in order to body fluid can not overflow, the back side of sanitary towel is waterproof construction, poor air permeability, thus women is often attended by the symptom generations such as tide is vexed, pruritus when in use, and comfortableness is poor.
Although general not concealed with the women position of sanitary towel's back side thin film contacts, but the panty crotch used due to the fashionable women of part is narrower, sanitary towel's back side thin film skin that is easy and femoribus internus produces and rubs, the sense of touch of thin film produces certain influence to the experience of user, and when putting up sanitary towel inferior, hand also can produce bad feel to sanitary towel's Back Material.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of air permeable waterproof casting films material, and according to producing the casting films with waterproof and breathable function after formula melting, and material is frivolous, soft-touch.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of air permeable waterproof casting films material, comprise: polyethylene from high pressure process, low-pressure polyethylene, linear polyethylene, metallocene, polypropylene and additive, described polyethylene from high pressure process, low-pressure polyethylene, linear polyethylene, metallocene, polypropylene and the additive percentage by weight shared by air permeable waterproof casting films material respectively is 26%, 35%, 17%, 10%, 5% and 7%, described additive comprises color masterbatch and opening agent, the weight percentage ranges of described color masterbatch shared by additive is 99.65% ~ 99.7%, the weight percentage ranges of described opening agent shared by additive is 0.3% ~ 0.35%.
In a preferred embodiment of the present invention, described opening agent accounts for 0.32% in additive.
In a preferred embodiment of the present invention, described color masterbatch accounts for 99.68% in additive.
In a preferred embodiment of the present invention, described color masterbatch is pink color masterbatch, White color masterbatch material or sky blue color masterbatch.
In a preferred embodiment of the present invention, described metallocene is multicomponent mixed matching catalyst.
The invention has the beneficial effects as follows: a kind of air permeable waterproof casting films material that the present invention points out, proportionally carry out heating and melting after mixing, coordinate waterproof ventilated membrane processing technique, more easily produce the casting films with waterproof and breathable function, and the casting films quality produced is frivolous, soft-touch, hot strength is high, be suitable as sanitary towel's backing material, improve the comfort of user.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of air permeable waterproof casting films material, comprise: polyethylene from high pressure process, low-pressure polyethylene, linear polyethylene, metallocene, polypropylene and additive, described polyethylene from high pressure process, low-pressure polyethylene, linear polyethylene, metallocene, polypropylene and the additive percentage by weight shared by air permeable waterproof casting films material respectively is 26%, 35%, 17%, 10%, 5% and 7%, described additive comprises color masterbatch and opening agent, the weight percentage ranges of described color masterbatch shared by additive is 99.65% ~ 99.7%, the weight percentage ranges of described opening agent shared by additive is 0.3% ~ 0.35%.
A kind of air permeable waterproof casting films of the present invention material with the addition of opening agent especially, and described opening agent accounts for 0.32% in additive.Opening agent can form monomolecular film at material interface, has anti stick, smooth, waterproof, damp proof, effect such as fouling resistance and antistatic.
Further, described color masterbatch accounts for 99.68% in additive.
Further, described color masterbatch is pink color masterbatch, White color masterbatch material or sky blue color masterbatch, than to be easier to receive by female consumer and like.
Further, described metallocene is multicomponent mixed matching catalyst, on the basis ensureing tensile property, reduces the thickness of casting films, improves comfort.
In sum, a kind of air permeable waterproof casting films material that the present invention points out, according to the proportioning of material, coordinates certain technique, can produce ultra-thin waterproof and breathable casting films, and the casting films soft-touch produced, and during use, comfortableness is good.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
