Abstract
The utility model relates to the technical field of new film materials, in particular to a multi-layer co-extrusion nylon release wind pipe with low cost. Compared with the prior art, the multi-layer co-extrusion nylon release wind pipe film is manufactured by adopting a multi-layer co-extrusion composite technology; an outer layer is made of polypropylene (PP), and inner layers include two to five layers and are made of polyamide 6 (PA6); the multi-layer co-extrusion nylon release wind pipe has the special effect of releasing of the outer layer. The multi-layer co-extrusion nylon release wind pipe combines the low surface tension of the PP and the high intensity of the PA6, therefore, the tensile strength of the wind pipe is two to three times as great as that of the PP, the elongation of the wind pipe is 1.5 times as great as that of the PA6, and the combination property of the wind pipe is better than that of the single PP and the single PA6. Most importantly, with the adoption of the multi-layer co-extrusion nylon release wind pipe, the surface tension of the film is successfully reduced to 29 mN/m from 38 mN/m, the film has a function of automatically releasing from resins, and meanwhile, the low cost is the biggest competitive advantage of the multi-layer co-extrusion nylon release wind pipe.
Description
Technical field
The present invention relates to the film new material technology field, the release airduct of particularly a kind of multi-layer co-extruded cheaply nylon.
Background technology
A kind of internally-arranged type airbag of existing composite blowing moulding arts demand; This airbag can break away from resin system after need soaking mould release; This film of the prior art all adopts the polyamide 6 of individual layer; Adopt its major defect of single layer structure to be that elongation is not enough, phenomenon such as occur being prone to break influences the moulding of product.
Summary of the invention
Be to solve existing defective of composite blowing moulding film and problem in the prior art, a kind of low cost, the release airduct of multi-layer co-extruded nylon that result of use is good are provided.
The technical scheme that the present invention is adopted for its technical problem of solution is: the release airduct of multi-layer co-extruded nylon of the present invention adopts two layers of structural design to five tunics being processed by polypropylene or polyamide 6, whenever adopts resin-bonding between two-layer.
The release airduct of multi-layer co-extruded nylon adopts the double-layer structure design.
The release airduct of multi-layer co-extruded nylon adopts three-decker, and ground floor adopts polypropylene, and the second layer adopts binder resin, and the 3rd layer is adopted polyamide 6.
The release airduct of multi-layer co-extruded nylon adopts five-layer structure, and ground floor and layer 5 adopt polypropylene, the second layer and the 4th layer of employing binder resin, and the 3rd layer is adopted polyamide 6.
The invention has the beneficial effects as follows: compared with prior art, the release airduct film of multi-layer co-extruded nylon of the present invention adopts multi-layer co-extruded complex technique, the outer polypropylene (PP) of selecting; Internal layer is selected polyamide 6 (PA6), comprises two layers to five layers scope, has outer release special-effect; The low surface tension of the comprehensive PP of the present invention and the high strength of PA6; Hot strength is two to three times of PP, and elongation is 15 times of PA6, and combination property is superior to simple PP and PA6.The most important thing is that the present invention successfully is reduced to 29mN/m with the surface tension of film by 38mN/m, has possessed the function of peeling off automatically with resin system, simultaneously, cost degradation is the maximum contention advantage of this kind of film.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the release airduct of multi-layer co-extruded nylon of the present invention is described further.

The specific embodiment
Extremely shown in Figure 3 like Fig. 1; The release airduct film of multi-layer co-extruded nylon of the present invention adopts multi-layer co-extruded complex technique, is made up of polypropylene and polyamide 6, adopts resin-bonding between polypropylene and the polyamide 6; The outer polypropylene (PP) of selecting; Internal layer is selected polyamide 6 (PA6), comprises two layers to five layers scope, has outer release special-effect.
As shown in Figure 1; Fig. 1 is first embodiment of the present invention; In the present embodiment, the release airduct of multi-layer co-extruded nylon adopts double-layer structure, and ground floor adopts polypropylene and binder resin compound O; The second layer adopts polyamide 6 (PA6) 2, and polypropylene and binder resin compound O and polyamide 6 (PA6) 2 are bonded together.
As shown in Figure 2, Fig. 2 is second embodiment of the present invention, and in the present embodiment, the release airduct of multi-layer co-extruded nylon adopts three-decker, and ground floor adopts polypropylene (PP) 1, and the second layer adopts binder resin 3, adopts polyamide 6 (PA6) 2 for the third time.
As shown in Figure 3, Fig. 3 is the 3rd embodiment of the present invention, in the present embodiment; The release airduct of multi-layer co-extruded nylon adopts five-layer structure; Ground floor and layer 5 adopt polypropylene (PP) 1, and the second layer and the 4th layer of employing binder resin adopt polyamide 6 (PA6) 2 for 3, the three layers.
Extremely shown in Figure 3 like Fig. 1; Comprehensive the foregoing description; The multi-layer co-extruded complex technique that the polypropylene that the release airduct film of multi-layer co-extruded nylon of the present invention adopts combines with polyamide 6 combines the high strength of the low surface tension and the polyamide 6 (PA6) of polypropylene (PP), and hot strength is two to three times of PP; Elongation is 15 times of PA6, and combination property is superior to simple PP and PA6.The most important thing is that the present invention successfully is reduced to 29mN/m with the surface tension of film by 38mN/m, has possessed the function of peeling off automatically with resin system, simultaneously, cost degradation is the maximum contention advantage of this kind of film.
According to embodiments of the invention describing the present invention property and nonrestrictive description, but should be understood that and do not breaking away under the situation of the relevant protection domain that limits claim that those skilled in the art can make change and/or revise.
