Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fishing rod, and more particularly to a fishing rod formed by wrapping a prepreg made of high-strength fibers impregnated with a synthetic resin.

Conventionally, fishing rods of this kind that have a pattern created by painting ink have a base coating layer on the surface of the rod wrapped with prepreg, and a base color layer is applied to the outer surface of this base coat layer. The upper layer had a pattern layer formed by screen printing or the like, and the upper layer of the pattern layer had a hard film-like clear layer that protected the pattern layer.

However, the bonding strength between the ground color layer and the pattern layer, the pattern layer and the clear layer, and the ground color layer and the clear layer is weak, and with the passage of time or when used in a hot and humid environment, If the surface of the pattern is damaged, this pattern layer will immediately peel off, resulting in the problem that the pattern that has been painstakingly applied will be ruined.

The present invention was invented in view of the above-mentioned problems, and the pattern layer does not peel off even when used under any adverse conditions or even if the surface is scratched. The purpose of the present invention is to provide a fishing rod with which the user can enjoy a brightly colored pattern forever, and which includes a first coating layer of an aliphatic urethane resin on the outer peripheral surface of the rod, and an outer surface of the coating layer. A pattern layer formed by thermal transfer of thermoplastic ink is provided on the outer surface of the rod rod, and a second coating layer of a transparent aliphatic urethane resin is provided on the outer surface of the pattern layer, and a pattern of a desired color is formed by the pattern layer on the outer periphery of the rod rod. It is characterized by a pattern that appears to appear.

An embodiment of the fishing rod of the present invention will be described below based on the drawings.

1 is a rod made by wrapping prepreg, which is made by impregnating high-strength fibers such as glass or carbon with synthetic resins such as epoxy, polyester, or phenol, around the outer periphery of a core material, and applying pressure and heating. A base coating layer 2 is applied to the outer peripheral surface of the rod rod 1. The base coating layer 2 is for reducing irregularities on the outer circumferential surface of the rod rod 1 to make it easier to form a pattern layer 3 to be described later, and the upper surface of this base coating layer 2 is made of aliphatic urethane resin. It has a first coating layer 4, and a pattern layer 3 made of an acrylic thermoplastic paint is formed on the upper surface of the first coating layer 4 by thermal transfer.

Further, on the outer surface of the pattern layer 3, a second coating layer 5 made of a transparent aliphatic urethane resin is formed, which covers the first coating layer 4 as well as the pattern layer 3.

Note that the first coating layer 4 is coated on the outer surface of the base coating layer 2.
When forming the pattern layer 3, it is necessary to perform it after the drying step of the base coat layer 2, but when forming the pattern layer 3 on the outer surface of the first coat layer 4 by thermal transfer, the first coat layer It is preferable to thermally transfer the pattern layer 3 in a semi-dry state before the layer 4 is completely cured and dried, and thermal transfer in such a state improves the adhesive bonding strength between the first coating layer 4 and the pattern layer 3. can be further improved.
This pattern layer 3 is printed on a synthetic resin film 6 as shown in FIG.
The pattern layer 3 is wrapped around the outer surface of the coating layer 4 for heating and thermal transfer, and the pattern layer 3 includes a peeling layer 3a that peels off from the film 6 during thermal transfer, a thermoplastic ink layer 31 forming the pattern portion, and the above-mentioned pattern layer 3. It consists of an adhesive layer 3b that adheres to the first coating layer 4. Also,
In this thermal transfer pattern layer 3, not only the pattern part but also the ground color part can be printed on the film 6, and the ground color part and the pattern part can be thermally transferred at the same time. There is no particular need to provide a layer on the outer surface of the coating layer 2 to provide a ground color. Then, a second coating layer 5 made of a transparent aliphatic urethane resin is applied to the outer surface of the pattern layer 3.

However, the first coating layer 4 in this embodiment
is the adhesive layer 3b of the base coat layer 2 and the pattern layer 3
The second coating layer 5 also adheres to the peeling layer 3a of the pattern layer 3 and the first coating layer 3 with extremely strong bonding force.
The pattern layer 3 is sandwiched between the first and second coating layers 4 and 5, and the first and second coating layers 4 are strongly adhered to the coating layer 4. , 5 makes it possible to prevent the pattern layer 3 from peeling off from the rod rod 1.

Next, we will introduce some of the test results.

The test method is a grid test (cuts that penetrate the paint film and reach the surface of the test plate (pole rod) are made using a sharp cutter knife,
Draw 11 parallel lines at 1 mm intervals to create 100 squares, then press adhesive cellophane tape, peel off the tape, and evaluate the peeling of the squares). This test was conducted under the same conditions as the stuffiness test (putting the test piece and 50 ml of water in a plastic bag, leaving it in a constant temperature bath kept at 80°C for 8 hours, and then leaving it at room temperature for 24 hours). It was carried out before and after. As a result, when an aromatic urethane resin was used as the first coating layer and an aromatic urethane resin was also used as the second coating layer, 80 out of 100 squares in the grid test before the stuffiness test were
About 100 squares came off, and the way the squares came off was not like one side of the square would come off, but almost all of them came off. After the stuffiness test, all 100 squares had peeled off, and the peeling was not just one side lifting up, but the entire area was peeling off. Next, if an aliphatic urethane resin is used for one of the first and second coating layers and an aromatic urethane resin is used for the remaining coating layer, 100 85 to 95 of the squares had peeled off, but since both of the coating layers mentioned above were made using aromatic urethane resin, in many cases only a portion of the squares had peeled off, and not all of the squares had peeled off. It never peeled off.

However, in the grid test after the stuffiness test, all 100 squares peeled off, and not only a part of the squares peeled off, but all of the squares peeled off in all parts. Furthermore, in the case where both the first and second coating layers in the above-mentioned embodiments of the present invention are made of aliphatic urethane resin, the results of the grid test are as follows. Even after the test, perfect test results were obtained, with not a single square showing any peeling.

As shown by the above test results, the fishing rod of the present invention, which is equipped with the first and second coating layers of aliphatic urethane resin and has a pattern layer thermally transferred between these coating layers, can withstand any adverse conditions. It has been demonstrated that the pattern layer does not peel off even when used in an environmentally friendly environment.

Incidentally, when a thermal transfer method is used to form the pattern layer as in the above embodiment, the ground color can also be formed at the same time. In this case, it is also possible to omit the base coating layer 2 and apply the first coating layer 4 directly to the outer surface of the rod rod 1 to form the pattern layer 3. When forming a pattern layer, the base coating layer 2 was indispensable. Therefore, when comparing the formation of the base coating layer 2 and the first coating layer 4, the formation of the first coating layer 4 is such that the pattern layer 3 can be transferred to its outer surface in a semi-dry state as described above. Since this process can be carried out more easily and in a shorter time than the formation of the base coating layer 2, overall working time and costs can be reduced.

Further, in the above embodiment, the clear layer in the form of a hard film as in the conventional example was not formed, but of course a clear layer may be formed on the outer surface of the second coating layer 5. In this case, since the bonding force between the clear layer and the second coating layer 5 made of aliphatic urethane resin is extremely strong, the clear layer can be firmly bonded, and furthermore, the outer surface of the clear layer is hard and hard to be scratched. Therefore, peeling of the pattern layer can be further reduced.

As explained above, in the fishing rod of the present invention,
They were able to form a patterned layer that retains its vivid color and does not peel off.
