Abstract
The utility model provides a with combined material of non -weaving cloth with multilayer structure of foam sheet constitution which comprises n+1 layer non -weaving cloth and n layer foam sheet, and wherein, foam sheet is polystyrene, polypropylene, polyethylene etc. And n is the positive integer, or get n=1 two -layer combined material promptly, the laminating becomes multilayer structure's combined material one by one. This combined material inhales sound sound insulation property and can adjust through the thickness that changes the non -weaving cloth, foam sheet's thickness or number of piles n value. This combined material can be used to various covers, screen material and light structure building materials and vehicle's inner decorative material.
Description
Technical field
The utility model relates to field of compound material, particularly a kind of composite of the sandwich construction formed with non-weaving cloth and foamed sheet.
Background technology
Non-weaving cloth is widely used in sound-adsorbing sound-insulating hung field, has the advantage of lightweight, environmental protection, efficient sound absorption.Air layer can strengthen the acoustically effective of non-weaving cloth under certain condition, even can replace the effect of non-weaving cloth at certain frequency domain.If can optimizing the arrangement of by non-weaving cloth and air layer sandwich construction, realize to the efficient obstruct of sound wave, then both can realizing sound-adsorbing sound-insulating hung function, alleviating again the weight of compound fabric.
At present for the MULTILAYER COMPOSITE acoustextile relating to non-weaving cloth, existing research has been paid close attention to and has been close to multilayer sound proof member that three dimensional foam material is formed (2005 years by non-weaving cloth, multilayer acoustical and thermal parts, patent publication No. CN1610611), the multilayer sound insulating material formed by polymer based thermoplastic material and fortifying fibre (2008, there is the structure of improvement, the supatex fabric of acoustics and hot property, patent publication No. CN101115890), the Multilayer composite sound-insulating fabric that the two-layer spunbond MINERVA layer be made up of PE and PP or PET in addition and the reinforcement intermediate layer be made up of PE or PET or PP filament fiber form (2008 years, a kind of multi-component spun-bonded non-woven reinforcement composite material and preparation method thereof, patent publication No. CN101260616).And and there are no relating to non-weaving cloth and the laminated MULTILAYER COMPOSITE non-weaving cloth of foamed sheet.
Summary of the invention
In order to solve the deficiency of existing technology, the utility model provides a kind of composite of the sandwich construction formed with non-weaving cloth and foamed sheet.
The technical solution that the utility model adopts is: a kind of composite of the sandwich construction formed with non-weaving cloth and foamed sheet, described composite is made up of n+1 layer nonwoven layer and n layer foamed sheet, described n value is positive integer, described nonwoven layer is positioned at foamed sheet both sides, and described foamed sheet thickness is 2mm.
Described composite is made up of 11 layers of nonwoven layer and 10 layers of foamed sheet.
Described foamed sheet is the one in polystyrene, polypropylene, polyethylene foam-material.
The porosity of described nonwoven layer is 85%-95%, and described nonwoven layer average pore size is 5-10 μm.
Described nonwoven layer average pore size is 8.8 μm.
The beneficial effects of the utility model are: the utility model provides a kind of composite of the sandwich construction formed with non-weaving cloth and foamed sheet, utilize non-weaving cloth and the alternately laminated of foamed sheet in the parameter such as thickness, density, form the composite non-weaving cloth of a kind of lightweight, efficiently sandwich construction to realize lightweight and to intercept sound wave efficiently.

Detailed description of the invention
The utility model provides a kind of composite of the sandwich construction formed with non-weaving cloth and foamed sheet, described composite is made up of n+1 layer nonwoven layer and n layer foamed sheet, described n value is positive integer, described nonwoven layer is positioned at foamed sheet both sides, and described foamed sheet thickness is 2mm.Wherein preferred version is that composite is made up of 11 layers of nonwoven layer and 10 layers of foamed sheet, described foamed sheet is the one in polystyrene, polypropylene, polyethylene foam-material, the porosity of described nonwoven layer is 85%-95%, described nonwoven layer average pore size is 5-10 μm, preferably, nonwoven layer average pore size is 8.8 μm.
To contribute to understanding the utility model by following examples, but not limit content of the present utility model.
The utility model composite non-weaving cloth structural representation is as Fig. 1, and shown n+1 layer non-weaving cloth and n layer foamed sheet are formed the composite of multilayer with certain thickness, certain number of plies.
As shown in Figure 2, n=1 and two-layer composite is got, one by one the composite of layer synthetic multi-layer structure.
The thickness of the non-weaving cloth shown in Fig. 1 and 2, porosity and average pore size can regulate.
The thickness of the foamed sheet shown in Fig. 1 and 2 can regulate.
The number of plies of the non-weaving cloth shown in Fig. 1 and 2 and foamed sheet can regulate.
