Description

Technical Field

[0001] The utility model relates to the technical field of integrally formed non-foaming PU and foaming PU, and particularly relates to a protective gear integrally formed by non-foaming PU and foaming PU. Background Art

[0002] In the prior art, at present, PU materials with excellent performance are widely used in the field of protective gears. The existing PU materials can be divided into two categories: non-foaming PU materials and foaming PU materials. The protective gears prepared with a single non-foaming material often have the advantages of high hardness, good wear resistance, and good protection effect, but have poor comfort during wearing, are prone to hard contact between the user's limbs and the protective gear, and do not have a shock-absorbing effect; the protective gears prepared with a single foaming material often have the advantages of soft shock absorption and good comfort, but have poor protection effect. At the same time, if a non-foaming material or a foaming material is laminated with other materials to form a protective gear, glue is required for bonding during lamination. Such a processing method increases the preparation process, reduces the production efficiency, and is not environmentally friendly.

[0003] In view of the problems in the related art that the protective gear prepared with a single non-foaming material has poor comfort during wearing, is prone to hard contact between the user's limbs and the protective gear, and does not have a shock-absorbing effect, and the protective gear prepared with a single foaming material has poor protection effect, there is still a lack of a better technical solution. Summary of the Utility Model

[0004] In view of this, it is necessary to provide a protective gear integrally formed by non-foaming PU and foaming PU, so as to at least solve the problems in the related art that the protective gear prepared with a single non-foaming material has poor comfort during wearing, is prone to hard contact between the user's limbs and the protective gear, and does not have a shock-absorbing effect, and the protective gear prepared with a single foaming material has poor protection effect.

[0005] An embodiment of the present application provides a protective gear integrally formed by non-foaming PU and foaming PU, which includes a non-foaming PU layer and a foaming PU bottom layer, and the non-foaming PU layer is integrally formed on the surface of the foaming PU bottom layer through a forming mold; wherein, the non-foaming PU layer is made of a non-foaming PU material with wear-resistant and shock-absorbing properties, and the foaming PU bottom layer is made of a foaming PU material with comfortable, soft and shock-absorbing properties.

[0006] In one of the embodiments, the non-foaming PU layer includes a non-foaming PU base layer and the non-foaming PU surface layer, the non-foaming PU surface layer is integrally formed on the surface of the non-foaming PU base layer through a forming mold, and the non-foaming PU base layer and the non-foaming PU surface layer are transparent or semi-transparent.

[0007] In one of the embodiments, the non-foaming PU layer further includes a fiber cloth intermediate layer, which is embedded between the non-foaming PU base layer and the non-foaming PU surface layer. A pattern layer is provided on one side of the fiber cloth intermediate layer close to the non-foaming PU surface layer, and the pattern on the pattern layer can be changed according to requirements.

[0008] The beneficial effects of the present utility model are as follows: The design of this application is reasonable and the structure is novel. The non-foaming PU layer is integrally formed on the surface of the foaming PU bottom layer through a molding die, so that the non-foaming PU layer and the foaming PU bottom layer form a double-layer protective gear. The outer layer uses the non-foaming PU layer, which has the advantages of wear resistance and shock absorption, and can effectively protect the user. The inner layer adopts the structural design of the foaming PU bottom layer, which has the advantages of comfortable wearing and soft shock absorption. At the same time, the structural design of the integral molding of the non-foaming PU layer and the foaming PU bottom layer does not require glue bonding, reduces the preparation process, improves the production efficiency, is environmentally friendly, reduces chemical pollution during bonding, and has strong practicability.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0016] Please refer to Figures 1 to 2 , an embodiment of this application provides a protective gear in which non-foaming PU and foaming PU are integrally formed, which includes a non-foaming PU layer 100 and a foaming PU bottom layer 200. The foaming PU bottom layer 200 is integrally formed on the surface of the non-foaming PU layer 100 through a foaming PU mold; wherein, the non-foaming PU layer 100 is made of a non-foaming PU material with wear-resistant and shock-absorbing properties, and the foaming PU bottom layer 200 is made of a foaming PU material with comfortable, soft and shock-absorbing properties.

[0017] It should be noted that the non-foaming PU layer 100 is integrally formed on the surface of the foaming PU bottom layer 200 through a forming mold, so that the non-foaming PU layer 100 and the foaming PU bottom layer 200 form a double-layer protective gear. The outer layer uses the non-foaming PU layer 100, which has the advantages of wear resistance and shock absorption and can effectively protect the user. The inner layer uses the structural design of the foaming PU bottom layer 200, which has the advantages of comfortable wearing, softness and shock absorption.

[0018] Please refer to Figures 1 to 4 , as a further improvement of this embodiment, the non-foaming PU layer 100 includes a non-foaming PU base layer 300 and a non-foaming PU surface layer 400. The non-foaming PU surface layer 400 is integrally formed on the surface of the non-foaming PU base layer 300 through a forming mold. The non-foaming PU base layer 300 and the non-foaming PU surface layer 400 are transparent or semi-transparent.

[0019] As a further improvement of this embodiment, the non-foaming PU layer 100 further includes a fiber cloth intermediate layer 500. The fiber cloth intermediate layer 500 is embedded between the non-foaming PU base layer 300 and the non-foaming PU surface layer 400. A pattern layer is provided on one side of the fiber cloth intermediate layer 500 close to the non-foaming PU surface layer 400, and the pattern on the pattern layer can be changed according to requirements.

[0020] It should be noted that by adopting the transparent or semi-transparent non-foaming PU base layer 300 and the non-foaming PU surface layer 400, while the pattern layer on the fiber cloth intermediate layer 500 can be revealed, the non-foaming PU material has excellent hardness and wear resistance, which can effectively protect the pattern on the fiber cloth intermediate layer 500 from external damage, and is not prone to fading or color change. The pattern on the fiber cloth intermediate layer 500 can be stored for a long time and still look new after long-term use, having the advantages of grand and beautiful appearance. At the same time, the structural design of embedding the fiber cloth intermediate layer 500 between the non-foaming PU base layer 300 and the non-foaming PU surface layer 400 replaces the traditional process of embedding the fiber cloth in the non-foaming PU material and printing the pattern on the outer surface of the non-foaming PU material by screen printing. There is no need to use chemical agents such as cleaning agents and treatment agents, thus avoiding the problem that chemical agents are not environmentally friendly during use, easily causing environmental pollution during the preparation process, and harming the physical health of users.
