Abstract
The utility model discloses a kind of TPU compound nonwoven cloths, including TPU sandwich layers, the TPU sandwich layers both sides are respectively equipped with nonwoven layer, polyethylene thin layer is provided with the outside of the nonwoven layer, and it is filled with hot melt adhesive layer between nonwoven layer and TPU sandwich layers, several webs are also filled between the TPU sandwich layers and nonwoven layer, formed between the TPU sandwich layers and nonwoven layer by heating PUR coated thermoplastic, the web is penetrated and connected between TPU sandwich layers and nonwoven layer and the polyethylene thin layer of outer surface, it is carved with a series of anti-slip veins in the polyethylene thin layer outer surface, with certain toughness, original curved surface can be recovered after use, prevent fold damaged, web can improve the bonding strength between interlayer, the other structures such as anti-slip veins can be added on polyethylene thin layer, using PUR composite thermoplastic, compressed thickness, improve the scope of application, the structural strength and stability of compound nonwoven cloth are all greatly improved on the whole, Compound Degree is more preferable.
Description
Technical field
The utility model is related to technical field of composite materials, specially a kind of TPU compound nonwoven cloths.
Background technology
Nonwoven cloth material has been achieved for very big progress, in particular with Material cladding with development in recent years
Development, increasing composite has been appeared in the visual field of people.Due to nonwoven cloth material have ventilative, light weight and
The characteristics of not combustion-supporting and filterability is waited well, is widely used.Current nonwoven cloth material species is various, but most of
Nonwoven cloth material there is following defect all the time：Firstly, since non-woven fabrics does not have fibre structure, therefore for the intensity of material
For be that inadequate and traditional nonwoven cloth material is all that, with very big pliability, quality is softer, without certain
Independent profile, such non-woven fabrics will cause breakage due to long-term fold in actual use；Secondly it is exactly
For existing nonwoven cloth material, majority uses direct composite construction, and the thickness ratio of non-woven fabrics is larger on the whole, one
A little special occasions are using will have limitation；Finally, due to composite construction, on the surface of nonwoven cloth material
Processing has great defective.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of TPU compound nonwoven cloths, including TPU cores
Layer, the TPU sandwich layers both sides are respectively equipped with the outside of nonwoven layer, the nonwoven layer and are provided with polyethylene thin layer, and in non-woven fabrics
Hot melt adhesive layer is filled between layer and TPU sandwich layers, several webs are also filled between the TPU sandwich layers and nonwoven layer,
Formed between the TPU sandwich layers and nonwoven layer by heating PUR coated thermoplastic, the web penetrates TPU sandwich layers and nothing
Spin and connected between layer of cloth and the polyethylene thin layer of outer surface, a series of anti-slip veins are carved with the polyethylene thin layer outer surface.
As a kind of preferred technical scheme of the utility model, the thickness between the TPU sandwich layers and nonwoven layer is
Seamless filling between 0.01mm, and hot melt adhesive layer and TPU sandwich layers and nonwoven layer.
As a kind of preferred technical scheme of the utility model, the hot melt adhesive layer uses PUR water-base cement type polyurethanes.
As a kind of preferred technical scheme of the utility model, it is in double tree-shaped interconnections on longitudinal direction that the web, which is in,
It is in netted interconnection in the plane.
Compared with prior art, the beneficial effects of the utility model are：The TPU compound nonwoven cloths, by being provided with bilayer
Nonwoven layer folder TPU sandwich layers, the performance mixed binding of two kinds of materials of non-woven fabrics and TPU is got up, with certain toughness, when making
Original curved surface can be recovered after, prevent fold damaged, and the web added between nonwoven layer folder TPU sandwich layers can
To improve the bonding strength between interlayer, the polyethylene thin layer on surface is added, and can be added on polyethylene thin layer anti-skidding
The other structures such as line, using PUR composite thermoplastic, compressed thickness improves the structure of the scope of application, on the whole compound nonwoven cloth
Strength and stability is all greatly improved, and Compound Degree is more preferable.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
In figure：1-TPU sandwich layers；2- nonwoven layers；3- polyethylene thin layers；4- hot melt adhesive layers；5- webs；6- anti-slip veins.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of TPU compound nonwoven cloths, including TPU sandwich layers 1,
The both sides of TPU sandwich layers 1 are respectively equipped with nonwoven layer 2, and the outside of nonwoven layer 2 is provided with polyethylene thin layer 3, and in non-woven fabrics
Hot melt adhesive layer 4 is filled between 2 and TPU of layer sandwich layers 1, several are also filled between the TPU sandwich layers 1 and nonwoven layer 2 fine
Net 5 is tieed up, is formed between the TPU sandwich layers 1 and nonwoven layer 2 by heating the coated thermoplastic of hot melt adhesive layer 4, the web 5 is worn
Connected between saturating TPU sandwich layers 1 and nonwoven layer 2 and the polyethylene thin layer 3 of outer surface, the outer surface of polyethylene thin layer 3 is carved with
A series of anti-slip veins 6.
Preferably, the thickness between the TPU sandwich layers 1 and nonwoven layer 2 is 0.01mm, and hot melt adhesive layer 4 and TPU cores
Seamless filling between layer 1 and nonwoven layer 2；The hot melt adhesive layer 4 uses PUR water-base cement type polyurethanes；The web 5 is in vertical
Upwards in double tree-shaped interconnections, in the plane in netted interconnection.
Specifically used mode and advantage：The TPU compound nonwoven cloths, TPU sandwich layers are pressed from both sides by the nonwoven layer for being provided with bilayer,
The performance mixed binding of two kinds of materials of non-woven fabrics and TPU is got up, with certain toughness, original song can be recovered after use
