Abstract
The invention discloses a durable air-permeable waterproof composite material. The durable air-permeable waterproof composite material sequentially consists of a first low-density polyethylene (LDPE) layer, an aluminum film, a second LDPE layer and a non-woven fabric from top to bottom. Compared with the prior art, the invention has the advantages that the durable air-permeable waterproof composite material has excellent water resistance and high durability, has a warm-keeping effect when wrapped tightly, has high air permeability after being stretched, is favorable for emitting moist and hot water vapor from a raincoat when worn, is convenient to wash, has a long service life and a wide application range, and can also be used for sun blocks of electromobiles, automobiles and the like, and an inner layer cannot fall off easily. The preparation method is simple, and the industrialized production can be realized.
Description
Technical field
The present invention relates to a kind of composite, relate in particular to a kind of durable air permeable waterproof composite.
Background technology
Along with growth in the living standard; People are also increasingly high to the material requirement of daily necessities, and 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 processed 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, is blown up easily, reduces rainproof function, and not environmental protection.
Summary of the invention
Goal of the invention: in order to solve the deficiency of prior art, the invention provides a kind of durable air permeable waterproof composite, shortcomings such as the material internal layer is prone to come off in the prior art to overcome, service life is not long, airtight, easy dirty inconvenience cleaning.
The present invention 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 of the present invention, it is made up 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 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 present invention compared with prior art has the following advantages: have good water proofing property, wrap and have thermal effect, open the back good permeability; Aqueous vapor damp and hot when helping wearing 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, sunshades such as automobile retaining uses.Preparation method of the present invention is simple, can realize suitability for industrialized production.
