Abstract
The utility model discloses a durable air-permeable waterproof composite material, sequentially comprising a first LDPE (Low-Density Polyethylene) layer, an aluminum film, a second LDPE layer and a nonwoven cloth from top to bottom. Compared with the prior art, the durable air-permeable waterproof composite material has the advantages that the water tightness is good; the warm-keeping function is achieved after the composite material is wrapped tightly, and the air permeability is good after the composite material is opened so that hot moisture can be dissipated from a raincoat when people wear the rain coat; and the cleaning is convenient, the inner layer hardly falls off, the durability is good, the service life is long, and the service range is wide; and the composite material also can be used for shading sunshine for an electric power cart, an automobile and the like. The process for preparing the material is simple and can be produced industrially.
Description
Technical field
The utility model relates to a kind of composite, relates in particular to a kind of durable air permeable waterproof composite.
Background technology
Along with growth in the living standard, people require also more and more higher to the material of daily necessities, common material can not satisfy people's demand, for example, people can be with umbrella or raincoat in case rain when trip, the rain cape of buying at ordinary times generally is to be made by oxford, PVC, and this material is more thick and heavy and peculiar smell is arranged, and is airtight.Disposable rain cape is too thin, and is insecure, easily is blown up, and reduces rainproof function, and not environmental protection.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the utility model provides a kind of durable air permeable waterproof composite, the shortcomings such as the material internal layer easily comes off in the prior art to overcome, not long, airtight, easy dirty inconvenience cleaning in service life.
The utility model also provides the preparation method of above-mentioned durable air permeable waterproof composite.
Technical scheme: in order to realize above purpose, a kind of durable air permeable waterproof composite described in the utility model, it is comprised of a LDPE layer, aluminium film, the 2nd LDPE layer, nonwoven from top to bottom successively.
The thickness of a described LDPE layer is 20 ~ 50um; The thickness of described aluminium film is 10 ~ 40um; The thickness of described the 2nd LDPE layer is 20 ~ 50um; The thickness of described nonwoven is 0.15 ~ 0.4mm.
Make the method for above-mentioned durable air permeable waterproof composite, comprise the steps:
A, LDPE is extruded under 320～350 ℃ condition, drench on nonwoven, form the 2nd LDPE layer;
B, adopt corona machine to carry out sided corona treatment on the surface of the 2nd LDPE layer, then the plated aluminum film;
C, LDPE is extruded under 320～350 ℃ condition, drench on the aluminium film, form a LDPE layer, be described durable air permeable waterproof composite.
The application of above-mentioned durable air permeable waterproof composite in rain cape.
Beneficial effect: the utility model compared with prior art has the following advantages: have good water proofing property, wrap and have thermal effect, open rear good permeability, aqueous vapor damp and hot when being conducive to wear sheds in raincoat, is convenient to clean, the internal layer difficult drop-off, durability is strong, long service life, and the scope of application is extensive, can also be used for battery truck, the sun shields such as automobile use.The utility model preparation method is simple, can realize suitability for industrialized production.
