[0048] Therefore, it is necessary to provide an embossed, resin-impregnated rope end with a stable embossed pattern shape and good effect, as well as its manufacturing method.

[0049] For example, please refer to Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the embossed and impregnated rope end provided in an embodiment of this application. To more clearly illustrate the structure of the embossed and impregnated rope end, the following will describe the embossed and impregnated rope end and its preparation method in conjunction with the accompanying drawings.

[0050] The preparation method of embossed and resin-impregnated rope ends includes the following steps:

[0051] Shape the rope end to obtain a shaped rope end;

[0052] A resin-impregnated layer 110 is formed on the surface of the shaped rope end to obtain a resin-impregnated rope end.

[0053] A preset embossing is formed on the dipped rope head by high-frequency wave treatment.

[0054] In the method for preparing the embossed and impregnated rope end of this application, the rope end is first shaped to form a shaped rope end, which helps to form a more uniform and firmly bonded impregnated layer 110 on the surface of the shaped rope end during the subsequent impregnation process. Then, a uniform and firmly bonded impregnated layer 110 is formed on the surface of the shaped rope end to obtain the impregnated rope end. By performing high-frequency wave treatment on a predetermined position of the impregnated rope end, an embossed and impregnated rope end with a stable embossed pattern shape and good effect can be obtained.

[0055] In some embodiments, the rope end is shaped using high-frequency vibration waves. Before shaping, the yarns at the rope end are loosely arranged and fluffy. During the impregnation process in this state, the impregnation slurry will penetrate the rope end surface differently, resulting in uneven coating thickness after curing. This application utilizes the energy of high-frequency vibration waves to gradually tighten and fix the yarns at the rope end, achieving a shaping effect and making the surface of the rope end more uniform and smooth. This, in turn, forms a uniform and firmly bonded impregnation layer 110 during the impregnation process, effectively avoiding adverse effects on subsequent embossing processes caused by uneven coating.

[0056] Optionally, an ultrasonic machine is used for the shaping operation. Optionally, the ultrasonic machine is model YBZ-SX15K-pro.

[0057] In some embodiments, the ultrasonic machine shapes at a frequency of 12k to 18k. Alternatively, the ultrasonic machine may use a frequency of 12k, 13k, 14k, 15k, 16k, 17k, 18k, or other parameters within the range of 12k to 18k.

[0058] In some embodiments, the ultrasonic machine's shaping power is 2kW to 3kW. Optionally, the ultrasonic machine's power can be 2kW, 2.2kW, 2.4kW, 2.6kW, 2.8kW, 3kW, or other parameters within the range of 2kW to 3kW.

[0059] In some embodiments, the ultrasonic shaping time is 1s to 3s. Alternatively, the ultrasonic shaping time can be 1s, 1.5s, 2s, 2.5s, 3s, or other parameters within the range of 1s to 3s.

[0060] In some implementations, a high-frequency indenter is used for high-frequency wave processing.

[0061] In some embodiments, the current for high-frequency wave processing of the high-frequency embossing machine is 23A to 28A. Optionally, the current can be 23A, 24A, 25A, 26A, 27A, 28A, or other parameters within the range of 23A to 28A.

[0062] The power of the high-frequency wave processing of the high-frequency indentation machine is 4kW to 6kW. Optionally, the power of the high-frequency wave processing can be 4kW, 4.5kW, 5kW, 5.5kW, 6kW, or other parameters within the range of 4kW to 6kW.

[0063] The high-frequency wave processing time is 2s to 5s. Optionally, the high-frequency wave processing time can be 2s, 3s, 4s, 5s, or other parameters within the range of 2s to 5s.

[0064] In some embodiments, the impregnation layer 110 includes a substrate coating 111 and a surface coating 113 located on the side of the substrate coating 111 away from the shaping rope head.

[0065] The substrate coating 111 comprises, by weight parts, the following raw materials:

[0077] Optionally, in the raw materials for preparing the surface coating 113, the mass fraction of silicon dioxide can be, but is not limited to, 0.5 parts, 1 part, 1.5 parts, 2 parts, 2.5 parts, 3 parts, 3.5 parts, 4 parts, or other fractions within the range of 0.5 parts to 4 parts.

Maintaining the mass fraction of curing agent II within the above range helps to form a surface coating 113 with a suitable crosslinking density, thereby improving the flexibility of the surface coating 113 and making it less prone to cracking during embossing or later use.

[0080] In some embodiments, the step of forming the impregnated layer 110 includes:

[0081] The raw materials for preparing the mixed substrate coating 111 are used to form a substrate slurry. The substrate slurry is coated on the surface of the shaped rope head and cured to form a resin-impregnated rope head precursor with the substrate coating 111.

[0082] The raw materials for preparing the mixed surface coating 113 are mixed to form a surface slurry. The surface slurry is then coated on the surface of the impregnated rope head precursor and cured to form an impregnated layer 110.

[0134] The preparation steps of substrate coating 111 are as follows: The raw materials for preparing substrate coating 111, by mass, are 48 parts of aqueous polyurethane dispersion, 1 part of aziridine curing agent, 49 parts of water, and 2 parts of silica. The aqueous polyurethane dispersion is added to a feeding tank, and water and silica are added under stirring. After uniform dispersion, the aziridine curing agent is added and stirred to obtain a surface slurry with a viscosity of approximately 300 mPa·s. The substrate slurry is coated onto the surface of the shaped rope end and cured at room temperature to form a resin-impregnated rope end precursor with substrate coating 111.

[0135] The preparation steps of the colored coating 112 are as follows: By mass, the raw materials for preparing the colored coating 112 are 78 parts of an aqueous polyurethane dispersion, 3 parts of a aziridine curing agent, 12 parts of water, and 7 parts of a blue paste. The aqueous polyurethane dispersion is added to a feeding tank, and water and the color paste are added while stirring. After uniform dispersion, the aziridine curing agent is added and stirred to obtain a color paste with a viscosity of approximately 300 mPa·s. The color paste is then coated onto the surface of the shaped rope end and cured at room temperature to form the colored coating 112.

[0136] The preparation steps of surface coating 113 are as follows: The raw materials for surface coating 113, by mass, are 48 parts of aqueous polyurethane dispersion, 1 part of aziridine curing agent, 49 parts of water, and 2 parts of silica. The aqueous polyurethane dispersion is added to a feeding tank, and water and silica are added under stirring. After uniform dispersion, the aziridine curing agent is added and stirred to obtain a surface slurry with a viscosity of approximately 300 mPa·s. The surface slurry is coated onto the surface of the impregnated rope head precursor with colored coating 112 and cured at room temperature to form impregnated layer 110, thus obtaining the impregnated rope head.

[0137] (3) Forming the preset embossing

[0138] The high-frequency wave treatment using a high-frequency embossing machine forms a pre-set mold pattern on the end of the glue-impregnated rope, which is then naturally cooled to obtain the embossed glue-impregnated rope end.

[0139] test

[0140] The embossing effect of the embossed resin-impregnated rope ends obtained in Examples 1-3 was observed using a magnifying glass. The embossed resin-impregnated rope end of Example 1 exhibited a superior embossing texture, with a smooth transition at the outer edge and a flat inner surface. Compared to Example 1, Example 2 showed a rougher texture at the outer edge, and the internal structure of the embossed texture in Example 3 showed slight deformation.
