Description

Technical Field

[0001] This invention relates to the field of chemical fiber paper tube technology, and in particular to a high-strength tear-resistant chemical fiber paper tube. Background Technology

[0002] Currently, the paper tubes used in chemical fiber textiles are basically made entirely of paper. Existing paper tubes often bend and deform due to their poor strength, which can easily lead to damage to the paper tube and the items wrapped around it. During use, it has been found that they will burn when exposed to an open flame, posing a certain safety hazard. Utility Model Content

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a high-strength tear-resistant chemical fiber paper tube, which improves the overall structural strength of the paper tube, has good compressive strength, and effectively prevents deformation.

[0004] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution:

[0005] A high-strength tear-resistant synthetic fiber paper tube includes an outer tube, an inner tube disposed inside the outer tube, a reinforcing layer disposed between the outer tube and the inner tube, a flame-retardant layer disposed on the outer side wall of the outer tube, abrasion-resistant kraft paper disposed on the inner side wall of the inner tube, and abrasion-resistant coating layer disposed on the outer side wall of the abrasion-resistant kraft paper.

[0006] Furthermore, the reinforcing layer consists of several reinforcing plates fixedly disposed between the outer tube and the inner tube.

[0007] Furthermore, several of the reinforcing plates are fixedly connected to each other and form a continuous triangular structure.

[0008] Furthermore, the wear-resistant coating is an alumina ceramic coating.

[0009] Furthermore, the flame retardant is an inorganic flame retardant.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] (1) By setting a reinforcing layer, the overall structural strength of the paper tube is improved, the compressive strength is good, and deformation is effectively prevented. By setting a flame-retardant layer, the flame-retardant performance of the paper tube can be improved. Thus, compared with the existing technology, it solves the technical problem that the existing paper tube usually bends and deforms due to poor strength, which easily leads to damage to the paper tube and the wrapped items. It is also found that it will burn when exposed to an open flame, which poses a certain safety hazard.

[0012] (2) Abrasion-resistant kraft paper has high tear resistance, bursting energy and dynamic strength. Attached Figure Description

[0015] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0017] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the preceding and following related objects, which are high-strength tear-resistant synthetic fiber paper tubes.

[0018] Example 1:

[0019] like Figure 1 As shown, this embodiment provides a high-strength tear-resistant chemical fiber paper tube, which includes an outer tube 7, an inner tube 6 disposed inside the outer tube 7, a reinforcing layer 3 disposed between the outer tube 7 and the inner tube 6, a flame-retardant layer 5 disposed on the outer wall of the outer tube 7, abrasion-resistant kraft paper 1 disposed on the inner wall of the inner tube 6, and abrasion-resistant coating layer 2 disposed on the outer wall of the abrasion-resistant kraft paper 1.

[0020] A high-strength, tear-resistant synthetic fiber paper tube includes an outer tube 7, an inner tube 6 inside the outer tube 7, a reinforcing layer 3 between the outer tube 7 and the inner tube 6, a flame-retardant layer 5 on the outer wall of the outer tube 7, and abrasion-resistant kraft paper 1 on the inner wall of the inner tube 6. An abrasion-resistant coating layer 2 is applied to the outer wall of the abrasion-resistant kraft paper 1. The reinforcing layer 3 improves the overall structural strength and compressive strength of the paper tube, effectively preventing deformation. The flame-retardant layer 5 enhances the flame-retardant properties of the paper tube. Compared to existing technologies, this solves the technical problems of existing paper tubes often bending and deforming due to poor strength, easily leading to damage to the paper tube and wrapped items; and the safety hazard of ignition when exposed to open flames. The abrasion-resistant kraft paper 1 exhibits high tear strength, bursting strength, and dynamic strength.

[0021] Furthermore, the reinforcing layer 3 consists of several reinforcing plates 4 fixedly disposed between the outer tube 7 and the inner tube 6. When subjected to external pressure, the multiple reinforcing plates 4 enhance the supporting force, thereby improving the overall strength and compressive resistance.

[0022] Furthermore, several reinforcing plates 4 are fixedly connected to each other to form a continuous triangular structure. The good stability of the triangular structure can further improve the overall strength and compressive strength.

[0023] Furthermore, the wear-resistant coating uses alumina ceramic coating. Alumina ceramic coating has high Rockwell hardness, excellent wear resistance, and is lightweight.

[0024] Furthermore, the flame retardant is an inorganic flame retardant. The inorganic flame retardant is a 1:1 mixture of aluminum hydroxide and magnesium hydroxide, which forms a chemical flame retardant on the outside of the paper tube.

[0025] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
