Abstract
The utility model discloses a compound hose body, outside from to interiorly include in proper order that outer, the first glutinous agent of PE is outer, EVOH is outer, the glutinous agent skin of second, composite bed, PE inlayer, PE is outer to link to each other with EVOH is outer through first glutinous agent is outer, EVOH is outer to be connected with the composite bed through the glutinous agent of second is outer, wherein the composite bed includes a PE inlayer, EVOH inlayer, the 2nd PE inlayer, a PE inlayer and the 2nd PE inlayer are arranged respectively to the both sides of EVOH inlayer. The utility model discloses can solve the technical problem who how to improve hose thermal aging, gas barrier property.
Description
Technical field
This utility model relates to packaging field, a kind of composite soft tube body.
Background technology
Hose packing relates to the various aspects of life, including cosmetics, food, medicine etc..
Polyethylene i.e. PE has excellent processing characteristics, and chemical stability is also fine, is resistant to the corrosion of preferable soda acid, and little insoluble in common solvent, especially its water absorption under room temperature, the transparency is high, and has excellent low temperature resistant.At present conventional packaging tube is mainly made up of PE, but owing to polyethylene is very sensitive for environmental stress, uses the most merely the flexible pipe that polyethylene manufactures, and its heat-resistant aging, gas barrier property need further improvement.
Utility model content
The purpose of this utility model is to provide a kind of composite soft tube body, solves how to improve the technical problem of flexible pipe heat-resistant aging, gas barrier property.
Composite soft tube body, includes PE outer layer the most successively, first sticks agent outer layer, EVOH outer layer, second sticks agent outer layer, composite bed, PE internal layer;PE outer layer sticks agent outer layer by first and is connected with EVOH outer layer;EVOH outer layer sticks agent outer layer by second and is connected with composite bed;Wherein composite bed includes a PE internal layer, EVOH internal layer, the 2nd PE internal layer;The both sides of EVOH internal layer are respectively arranged a PE internal layer and the 2nd PE internal layer.
Described EVOH internal layer becomes cylinder;Glutinous agent internal layer is there also is provided on EVOH internal layer external cylindrical surface;EVOH internal layer and glutinous agent internal layer are combined into one and are open into and crossed longitudinally are arranged in inside a PE internal layer and the 2nd PE internal layer;Described EVOH internal layer inner hollow;There is inside described glutinous agent internal layer the bubble of 0.002-0.003 millimeter radius.
Described first stick agent outer layer, the second material sticking agent outer layer and glutinous agent internal layer is AD.
The beneficial effects of the utility model are: PE outer layer and PE internal layer are polyethylene layer, and it has good processing and chemical stability;EVOH outer layer and EVOH internal layer are same material i.e. ethylene-vinyl alcohol copolymer, the iris action of polyvinyl processability and vinyl alcohol polymer is combined by it, ethylene-vinyl alcohol copolymer not only shows fabulous processing characteristics, and gas, abnormal smells from the patient, spice, solvent etc. present the blocking effect of excellence.Owing to same ethylene combines, there is heat stability, can reuse completely containing EVOH laminated vessel.By EVOH being made cylinder and being wrapped in a PE internal layer and the 2nd PE internal layer inside, so while increasing the intensity of container, further improve its heat-resistant aging, gas barrier property;EVOH internal layer made inner hollow and is passed through air at glutinous agent internal layer and makes to have inside it micro bubbles, so making whole container have elasticity and prevent it from use deforming.
Accompanying drawing explanation
Fig. 1 is the sectional view of composite soft tube body;
1.PE outer layer in figure, 21. first stick agent outer layer, 22. second stick agent outer layer, 3.EVOH outer layer, 4. composite bed, 41.EVOH internal layer, 42. stick agent internal layer, 43. the oneth PE internal layers, 44. the oneth PE internal layers, 5.PE internal layer.
Detailed description of the invention
Refer to Fig. 1, the composite soft tube body in figure, include PE outer layer 1 the most successively, first stick agent outer layer 21, EVOH outer layer 3, second stick agent outer layer 22, composite bed 4, PE internal layer 5.
PE outer layer 1 and PE internal layer 5 is same material i.e. polyethylene, and this material has good stability and processing characteristics, is commonly used for the making of flexible pipe at present.
First sticks agent outer layer 21 and second sticks agent outer layer 22 and is AD material, and it is widely used in the making of flexible pipe equally, is attached on EVOH material by PE material by using this material.
EVOH outer layer 3 and EVOH internal layer 41 is EVOH material, it is ethylene-vinyl alcohol copolymer, the iris action of polyvinyl processability and vinyl alcohol polymer is combined by it, ethylene-vinyl alcohol copolymer not only shows fabulous processing characteristics, and gas, abnormal smells from the patient, spice, solvent etc. present the blocking effect of excellence.
Composite bed 4 includes EVOH internal layer 41, glutinous agent internal layer the 42, the oneth PE internal layer the 43, the 2nd PE internal layer 44;The material of EVOH internal layer 41 is EVOH, the material of glutinous agent internal layer 42 is AD, the material of the oneth PE internal layer 43 and the 2nd PE internal layer 44 be the side of PE, EVOH internal layer 41 or both sides or all position be arranged between a PE internal layer 43 and the 2nd PE internal layer 44 by glutinous agent internal layer 42.As EVOH internal layer 41 is made cylinder, its a diameter of 0.01-0.015 millimeter;Glutinous agent internal layer 42 is wrapped on EVOH internal layer 41 external cylindrical surface, and its thickness is 0.005-0.008 millimeter;EVOH internal layer 41 and glutinous agent internal layer 42 are combined into one and are open into and are longitudinally arranged between a PE internal layer 43 and the 2nd PE internal layer 44, and the thickness of a PE internal layer 43 and the 2nd PE internal layer 44 is 0.03-0.05;EVOH internal layer 41 inner hollow;The internal bubble with 0.002-0.003 millimeter radius of glutinous agent internal layer 42.
