Description
Technical field
The utility model relates to breathable membrane production device field, particularly relates to a kind of three-layer co-extruded breathable membrane production device.
Background technology
Present stage, internal and international upper ventilated membrane production line uses single screw extrusion machine to plastify raw material usually, mixing rear one-tenth simple layer material is extruded, and the product grammes per square metre of production is 20-60g/ ㎡.The manufacture of simple layer material is produced into breathable films, and the inside of film, top layer are the mixture of same content, and production technology is relatively simple.And for some properties of production, require that film surface has the film of special property or function, or in order to reduce costs, reduce material consumption, when product thickness requires that constant, product grammes per square metre reduces, adopt simple layer extrusion product then can not realize.
Utility model content
The utility model embodiment technical problem to be solved is, a kind of three-layer co-extruded utilization on ventilated membrane is produced is provided, for the use of new material provides possibility, improve the physical property of film, reach the three-layer co-extruded breathable membrane production device of object of energy-saving and emission-reduction.
Described three-layer co-extruded breathable membrane production device, comprise distributor, be arranged on the T-shaped die head below described distributor and be arranged on the extruder of top, described extruder comprises the first extruder and the second extruder, and described first extruder and the second extruder are connected with described distributor respectively by tube connector; The intermediate layer cavity of described distributor is communicated with described first extruder, the left and right two-layer cavity of described distributor is communicated with described second extruder respectively, material converges in distributor respectively by the first extruder, the second extruder, layering, be superimposedly then expressed into T-shaped die head, extrudes through die head homogeneous constant.
Described first extruder and the second extruder comprise net-changing device, tube connector, flange and elbow respectively, and described tube connector is connected with described net-changing device by flange, and adjacent two tube connectors are communicated with by elbow and are communicated with described distributor.
Implement the utility model embodiment, there is following beneficial effect:
The utility model uses three-layer co-extruded technology can according to product needed, and being particularly suitable for film two surfaces has the film of different performance particular/special requirement and have the breathable films of high performance requirements.The film that production property requires, every platform extruder can add and uses different raw material, through screw mixing, plastify, extrude after through undue orchestration uniform distribution to die head, then steady extruding sheet film.
Use three-layer co-extruded technology can use different materials according to different extruders, improve membrane structure, conventional raw material can be used as the base material of film at the internal layer of film, and the raw material of particular/special requirement can be added in two top layers, thus improve the physical property of film, reach the requirement of use.The film of three-layer co-extruded production is compared with simple layer extruder, three-layer co-extrudedly can produce 12g/ ㎡ ultralow gram weight breathable films, and product physical property reaches the Product Level of the 18g/ ㎡ that simple layer is produced, and thus can reach energy-conservation, the object that reduces discharging.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The three-layer co-extruded breathable membrane production device of the utility model embodiment, as shown in Figure 1, 2, 3, wherein the first extruder net-changing device 8 by flange 7 with duct coupling 6 with turn to elbow 5 and 3 break-in after connected with distributor 1 by flange 2; The net-changing device 9 of the second extruder by flange 10 with duct coupling 12 with turn to elbow 11 and 13 break-in after connected with distributor 1 by flange 14; The material that first extruder is extruded and the material that the second extruder is extruded converges in distributor, layering, be superimposedly then expressed into die head 4, extrudes through die head homogeneous constant.As shown in Figure 3,4, the material that first extruder is extruded is distributed into extrudate internal layer A in distributor, the material that second extruder is extruded is assigned to B, C two top layers according to the ratio uniform regulated in distributor, the extrudate of three levels is superimposed constant to be expressed on T-shaped die head afterwards, and T-shaped die head is extruded according to the die cavity regulated, film lip even width again.
The utility model uses three-layer co-extruded technology can according to product needed, and being particularly suitable for film two surfaces has the film of different performance particular/special requirement and have the breathable films of high performance requirements.The film that production property requires, every platform extruder can add and uses different raw material, through screw mixing, plastify, extrude after through undue orchestration uniform distribution to die head, then steady extruding sheet film.
Use three-layer co-extruded technology can use different materials according to different extruders, improve membrane structure, conventional raw material can be used as the base material of film at the internal layer of film, and the raw material of particular/special requirement can be added in two top layers, thus improve the physical property of film, reach the requirement of use.The film of three-layer co-extruded production is compared with simple layer extruder, three-layer co-extrudedly can produce 12g/ ㎡ ultralow gram weight breathable films, and product physical property reaches the Product Level of the 18g/ ㎡ that simple layer is produced, and thus can reach energy-conservation, the object that reduces discharging.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
