Technical Field

[0001] The present invention belongs to the technical field of PPSU plastic processing, and particularly relates to an adhesion method and a bottle body. Background Art

[0002] PPSU and silica gel are non-adhesive materials. For traditional PPSU and silica gel bottle bodies, after the PPSU bottle ring is injection-molded, glue needs to be applied at the adhesion position between the bottle ring and the silica gel bottle body, and then the silica gel bottle body is sleeve-injected to achieve the adhesion effect between PPSU and silica gel. During the glue application process, there are problems such as uneven glue application, defects caused by too much or too little glue application, and bottle body detachment, resulting in low production yield and production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide an adhesion method and a bottle body. For the bottle body injection-molded by the adhesion method of the present application, PPSU and silica gel are directly adhered without applying glue, avoiding the problems of poor glue application and silica gel bottle body detachment caused by poor glue application, and reducing the manufacturing cost.

[0004] To solve the problems mentioned in the above background art.

[0005] To achieve the above invention purpose, the technical solution adopted is:

[0006] In the first aspect, an adhesion method irradiates the adhesion part of the first material, and a first change occurs in the adhesion part after irradiation; the irradiated first material is sleeve-injected with the second material so that the adhesion part of the first material adheres to the second material.

[0007] The first aspect of the present application is further set as: the first material is made of PPSU plastic material, the second material is made of silica gel material, and the first change is the synthesis of hydroxy ether compounds from thioether compounds and aromatic alcohol compounds on the PPSU plastic.

[0008] The first aspect of the present application is further set as: the irradiation is ultraviolet lamp irradiation, the power range of the ultraviolet lamp is 40W - 15KW, and the irradiation duration range is 4S - 15S.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two elements. It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0025] A bonding method, as Figure 1 shown, irradiate the bonding area of the first material. After irradiation, a first change occurs in the bonding area. Then, perform die-cutting on the irradiated first material and the second material so that the bonding area of the first material and the second material are bonded together. Specifically, the first material and the second material themselves are substances without adhesiveness and cannot be directly bonded. After irradiation, the molecular layer at the irradiated area of the first material undergoes a first change. By performing die-cutting on the irradiated first material and the second material, the first material and the second material are bonded at the irradiated area of the first material.

[0026] In this embodiment, the first material is made of PPSU plastic material, and the second material is made of silicone material. The first change is that the thioether compound and the aromatic alcohol compound on the PPSU plastic synthesize a hydroxyether compound. The irradiation is ultraviolet lamp irradiation. The power range of the ultraviolet lamp is 40W - 15KW, and the irradiation duration range is 4S - 15S. Specifically, under ultraviolet lamp irradiation, the thioether compound and aromatic compounds such as aromatic ketone, aromatic aldehyde, or aromatic alcohol synthesize a polar molecule hydroxyether compound. The molecular formula of PPSU plastic contains an ether bond and an aromatic alcohol. The ether bond reduces the adhesion of PPSU plastic. After the PPSU plastic is irradiated by the ultraviolet lamp, the ether bond and the aromatic alcohol synthesize a hydroxyether compound, reducing the ether bond density in the PPSU plastic, thereby enhancing the adhesion of the irradiated surface of the PPSU plastic and enabling bonding with the silicone material during the subsequent bottle sleeving process. During the ultraviolet lamp irradiation process, the light energy and temperature of the ultraviolet lamp are related to the power of the ultraviolet lamp. For example, when the power of the ultraviolet lamp is 15KW, its energy is 850mJ / cm 2 , and the temperature is, and the irradiation duration is 8S.

[0027] A bottle body includes a bottle ring 1 and a bottle body 2. The above bonding method is used to bond the PPSU bottle ring 1 and the silicone bottle body 2. The bottle ring is made of PPSU plastic, and the bottle body is made of silicone material. A bonding ring 3 is provided on the bottle ring 1, and an inner embedding groove 4 is provided at the opening end of the bottle body 2. The bonding ring 3 matches the inner embedding groove 4, and the bonding ring 3 is bonded in the inner embedding groove 4 after being irradiated by ultraviolet light. Specifically, the inner embedding groove 4 has a certain depth, which can increase the bonding area between the bottle ring 1 and the bottle body 2, thereby enhancing the bonding effect.

[0028] Furthermore, at least two buckle positions 5 are provided on the bonding ring, and buckle blocks 6 matching the buckle positions 5 are provided in the inner embedding groove 4. Specifically, first, the bonding ring 3 of the bottle ring 1 is irradiated, and then the bottle body 2 and the bottle are sleeved. During the sleeving process, the silicone buckle blocks 6 are filled in the buckle positions 5 of the bonding ring 3, further strengthening the bonding between the silicone bottle body 2 and the PPSU bottle ring 1.

[0029] In the specific implementation process, an inner embedding wall 7 integrally connected with it is provided at the opening of the bottle body 2. Specifically, the inner embedding wall 7 increases the contact surface between the bottle body 2 and the bottle ring 1. The inner embedding wall 7 can bear a part of the external force, such as the impact force of shaking, twisting, or dropping, so that the bottle body 2 and the bottle are not easily broken at the bonding part.

[0030] It can be understood that a blocking ring 8 is provided at one end of the inner wall of the bottle ring 1 away from the bottle body 2. When the inner embedding wall 7 abuts against the inner wall of the bottle ring 1, the upper end of the inner embedding wall 7 abuts against the blocking ring 8, and the inner embedding wall 7 and the blocking ring 8 are on the same curved surface. The inner embedding groove 4 and the inner embedding wall 7 are provided with a first section difference 9, and the bonding ring 3 and the bottle ring 1 are provided with a second section difference 10. When the bonding ring 3 is bonded to the inner embedding groove 4, the first section difference 9 matches the second section difference 10.

[0031] In this embodiment, the bonding ring 3 is wavy, the embedded groove 4 is wavy and matches the bonding ring 3, and the snap ring is strip-shaped.

[0032] In summary, the present application provides an adhesion method and a bottle body. By irradiating the bonding part of the first material, a first change occurs in the bonding part after irradiation. The irradiated first material and the second material are subjected to overmolding, so that the bonding part of the first material and the second material are bonded. Specifically, the PPSU bottle ring 1 and the silicone bottle body 2 are bonded into a bottle body after being irradiated with ultraviolet light, without applying glue for bonding, avoiding the problem of poor gluing and the detachment of the silicone bottle body 2 caused by poor gluing, and reducing the manufacturing cost.

[0033] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
