Abstract
The utility model discloses a breathable composite membrane capable of preventing liquid permeation, which comprises a breathable thin layer, a non-woven layer and an adhesive layer, wherein the moisture permeability of the breathable thin layer is less than 5000g/n<2>.24h, water pressure resistance of the breathable thin layer is more than 2000mmH2O, and the breathable thin layer and the non-woven layer are bonded and fixedly connected through the adhesive layer. The breathable composite membrane capable of preventing liquid permeation has good air permeability and strong water pressure resistance, simple structure and low cost, and is convenient in use and good in handfeel.
Description
Technical field
The utility model relates to a kind of ventilative anti-Liquid Penetrant composite membrane.
Background technology
Medical cloth still adopts traditional woven fabric on China's hospital bed now, and woven fabric needs constantly to clean and every sheet on medical cloth to wash the life-span be average 5 times, and woven fabric exists weaves the cost height, having for health in hospital etc. also needs continuous sterilization under the higher environment, this has just improved consumer cost greatly.In addition, if wear woven fabric or the poor composite membrane of gas permeability when medical personnel perform the operation, the body conformance that not only affects hospital personnel also reduces operating efficiency greatly.Described problem not only can be run in hospital, all can run in the fields such as package packing supplies, maternal and child health articles for use, clean room, laboratory.
Summary of the invention
The purpose of this utility model is to provide a kind of ventilative anti-Liquid Penetrant composite membrane, good, the water-fast pressure of its permeability, simple in structure, low cost of manufacture, easy to use and good hand touch.
In order to reach above-mentioned purpose, the technical solution of the utility model is:
A kind of ventilative anti-Liquid Penetrant composite membrane comprises moisture permeability greater than 5000g/ ㎡ 24h, and water pressure resistance is greater than 2000mmH
2The breathable film layer of O, nonwoven layer and adhesive layer; Described breathable film layer and nonwoven layer are connected by adhesive layer is bonding.
Described breathable film layer up and down two surfaces respectively by adhesive layer and nonwoven layer is bonding is connected.
Described nonwoven layer is nonwoven layer.
The beneficial effects of the utility model are: a kind of ventilative anti-Liquid Penetrant composite membrane that the utility model provides, and its moisture permeability of passing through breathable film layer is greater than 5000g/ ㎡ 24h, and water pressure resistance is greater than 2000mmH
2The characteristics such as O make ventilative anti-good, the water-fast pressure of Liquid Penetrant composite membrane permeability after compound; Owing to adopt breathable film layer and nonwoven layer bonding by adhesive layer, it is simple in structure, low cost of manufacture and manufacturing form ventilatively prevents Liquid Penetrant composite membrane good hand touch.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment
As shown in Figure 1, a kind of ventilative anti-Liquid Penetrant composite membrane of present embodiment comprises moisture permeability greater than 5000g/ ㎡ 24h, and water pressure resistance is greater than 2000mmH
2The breathable film layer 1 of O, nonwoven layer 2 and adhesive layer 3; Described breathable film layer 1 and nonwoven layer 2 are by adhesive layer 3 bonding being connected.Described nonwoven layer 2 is nonwoven layer.
Ventilative anti-Liquid Penetrant composite membrane in the present embodiment adopts wet method composite processing technique.At first prepare breathable films and the raw material such as non-weaving cloth, glue.Next opening device, by setting certain tension force breathable films and nonwoven are transmitted respectively along the compound path trend, breathable films is when upper glue roller, pressure roller effect glue coated by upper glue roller is on breathable films, through the composite press roller place, make that breathable films and nonwoven are bonding to be connected.Breathable composite film after compound, its breathable films just form the breathable film layer 1 among the embodiment 1, and nonwoven just forms nonwoven layer 2, and glue just forms adhesive layer 3.
A kind of ventilative anti-Liquid Penetrant composite membrane that present embodiment provides, its moisture permeability of passing through breathable film layer is greater than 5000g/ ㎡ 24h, and water pressure resistance is greater than 2000mmH
2The characteristics such as O make good, the water-fast pressure of breathable composite film permeability after compound; Owing to adopt breathable film layer and nonwoven layer bonding by adhesive layer, it is simple in structure, low cost of manufacture and manufacturing form ventilatively prevents Liquid Penetrant composite membrane good hand touch.
Embodiment 2
As shown in Figure 2, a kind of ventilative anti-Liquid Penetrant composite membrane of present embodiment comprises moisture permeability greater than 5000g/ ㎡ 24h, and water pressure resistance is greater than 3000mmH
2The breathable film layer 1 of O, nonwoven layer 2 and adhesive layer 3; Described breathable film layer 1 and nonwoven layer 2 are by adhesive layer 3 bonding being connected.Described breathable film layer about in the of 1 two surfaces respectively by adhesive layer 3 and nonwoven layer 2 bonding being connected.Described nonwoven layer 2 is nonwoven layer.
The composite membrane of the ventilative anti-Liquid Penetrant in the present embodiment adopts the wet method complex machining process.At first prepare breathable films and the raw material such as non-weaving cloth, glue.Next opening device, by the some tension of setting breathable films and nonwoven are transmitted respectively along the compound path trend, breathable films is when upper glue roller, pressure roller effect glue coated by upper glue roller is on breathable films, through the composite press roller place, make that breathable films and nonwoven are bonding to be connected.Present embodiment breathable film layer about in the of 1 two surfaces bonding by adhesive layer 3 and nonwoven layer 2 respectively.After compound finishing for the first time, it is compound that itself and nonwoven are carried out second time wet method.The ventilative composite membrane of preventing Liquid Penetrant that composite membrane after compound just provides for present embodiment, its breathable films just forms the breathable film layer 1 among the embodiment 2, and nonwoven just forms nonwoven layer 2, and glue just forms adhesive layer 3.
A kind of ventilative anti-Liquid Penetrant composite membrane that present embodiment provides, its moisture permeability of passing through breathable film layer is greater than 5000g/ ㎡ 24h, and water pressure resistance is greater than 3000mmH
2The characteristics such as O make good, the water-fast pressure of breathable composite film permeability after compound; Owing to adopt breathable film layer and nonwoven layer bonding by adhesive layer, it is simple in structure, low cost of manufacture and manufacturing form ventilatively prevents Liquid Penetrant composite membrane good hand touch.
