Field of the Invention The present invention relates to a method of manufacturing a synthetic resin coating material for continuously producing a synthetic resin coating material by coating a core material with a ground color synthetic resin, and particularly to an agricultural and horticultural art. The present invention relates to a technique suitable for automatically applying a dark pattern peculiar to natural bamboo to the surface of a pseudo-bamboo material used as a support post or bamboo fence.

得られない。2. Description of the Related Art Conventionally, a technique for obtaining a synthetic resin coating material by integrally applying a synthetic resin for ground color such as green or yellow to an outer periphery of a synthetic resin or metal core material by an extruder is known. It is. Furthermore, by temporarily stopping the delivery of the core material, the nodes are raised at predetermined intervals, and in appearance,
It is relatively easy to obtain a pseudo-bamboo material that is very similar to natural bamboo. At this time, similar to natural bamboo, adding a dark pattern peculiar to the nodes of bamboo means that the dark pattern is the color of the bamboo. Since they are different colors from each other, they cannot be formed at the same time, and unless they have the dark pattern, an appearance very similar to natural bamboo cannot be obtained.

る。Therefore, conventionally, a dark pattern is applied to the nodes of the artificial bamboo material by the following various means. That is, as the first means, a dark-colored synthetic resin is kneaded into the synthetic resin for the ground color from the beginning, and the synthetic resin is retained by stopping the core material to form a single-layered molding in which the nodes are darkened. As a means, a synthetic resin for the dark color is prepared separately from the synthetic resin for the ground color, and a two-layer molding in which the nodes are raised with the synthetic resin for the dark color on the film of the synthetic resin for the ground color, as a third means. Is that dark transfer printing was performed on the nodes by the transfer roller.

There is a disadvantage that it is difficult to obtain a gradation in which the shading changes, and in the third means, the boundary between the ground color and the dark pattern clearly appears, and there is also a disadvantage that a natural gradation cannot be obtained. However, it was difficult to apply a dark pattern very similar to natural bamboo on the nodes.

In the production method, a means of spraying a paint on the surface of the synthetic resin coating material sent from the extruder was used. According to the second aspect of the present invention, based on the above-described means, the core material delivered from the extruder is intermittently stopped so that the nodes are raised at predetermined intervals.
At the time of stopping the core material, a means of spraying a paint on the previously formed node was selectively used. Furthermore, in any one of the above-mentioned means, a means for spraying a paint at a warm stage before the solid resin for ground color is cooled and solidified is selectively used. Here, the synthetic resin coating material is defined to include not only a tubular material such as a round tube or a split tube but also a plate-like material such as a flat plate or a corrugated plate.

Paint supply device 6 for supplying paint under pressure or high-speed airflow
a is connected to a hollow tubular body 6c bent in a semicircular shape through a straight tubular flow path 6b.
In the inner peripheral surface of c, a fine orifice 6 facing the surface of the artificial bamboo material
d is formed in plurality. The inner diameter of the semicircular tubular body in the spraying device is, of course, a diameter through which the nodes of the artificial bamboo material can pass, so that the artificial bamboo material can pass through.

It is arranged at a position corresponding to the node 3 and is configured so that the spraying of the paint by the spray device 6 is performed in synchronization with the stop of the core material 1.

Further, at this time, since the atomized paint is sprayed from the spraying device 6 through the ejection holes 6d, a gradation in which the shading of the dark pattern changes naturally at the boundary with the ground color can be obtained, and a more natural color can be obtained. A pseudo bamboo material very similar to bamboo can be provided.

The number and injection timing are not limited to these. For example, a plurality of the spraying devices 6 may be installed in accordance with the interval at which the nodes 3 are formed, and a dark pattern may be applied to a plurality of nodes 3 at one time by stopping the core 1 once. In this case, it is needless to say that the injection interval is adjusted so that the paint is not injected again to the knot portion provided with the pattern. When it is desired to apply a pattern to the entire covering material, the spraying device 6 may be installed at an arbitrary position in front of the extruder, and the paint may be sprayed while the core material 1 is being delivered. Also in this case, it is possible to provide a variety of patterns.

It is preferably set before the resin of the ground color film of the artificial bamboo material is cooled and solidified. Therefore, a second embodiment of the present invention based on such a viewpoint will be described with reference to FIG. In the present embodiment, it is assumed that a pipe-shaped material is used as a core material and a dark pattern is applied to a node of the round bamboo-like pseudo-bamboo material on the assumption that a round bamboo-like pseudo-bamboo material is formed. . Here, the shaping of the round bamboo-like pseudo-bamboo material and the shaping of the node portion 3 are realized by the same principle as the extruder 4 exemplified in the first embodiment.

Different from one embodiment. In addition, in this embodiment, as shown in FIG. 5, two semi-circular spray devices 6 used in the first embodiment are vertically arranged corresponding to the fact that the target artificial bamboo material is a round bamboo.
