Abstract

PURPOSE:To manufacture a non-slip plate provided with high non-slip effect and saving labor in a manufacturing process by forming an outer peripheral face of a roller for a roll coater for applying a coating material to a base in a position close to the base and providing the coating material of shape retaining properties for retaining the recessed and projected shape when the coating material is applied to the base. CONSTITUTION:A non-slip plate is manufactured by forming an outer peripheral face 4 of a roller 3 for a roll coater 2 for applying a coating material B to a base A in a position close to the base 4 for non-slip plate, while the coating material B is manufactured by providing the shape retaining properties for retaining recesses and projections when the coating material is applied to the base A. The shape retaining properties mean curing the coating material B with recesses and projections as they are so that the recesses and projections on the outer are peripheral face 4 of the roll 3-transferred to the base A just as they are to retain the primary shape of recesses and projections, and the slight deformation of recesses and projections, for example, the reduction of the height of recesses and projections by approximately 60% on the base 4, is allowed. Therefore, the recesses and projections can be formed on the base A to improve the non-slip effect, and also the recesses and projections are formed in an automatic coating process.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip plate which can be formed with a non-slip irregularity for convenience on the surface of a step plate of a stair, and which can efficiently manufacture a non-slip plate having a high anti-slip effect without much labor. Manufacturing method.

[0002]

2. Description of the Related Art The surface of various board materials such as stairs that require anti-slip is usually subjected to anti-slip treatment by attaching rubber or grooving.

[0003]

However, the rubber or the groove tends to have a slippery effect, for example, when the surface is wet with water, so that the anti-slip effect tends to be insufficient.

In addition, the sticking work and groove processing of rubber require the use of an adhesive in addition to rubber or the labor for groove processing.

The present inventor has completed the present invention by paying attention to a coating agent which is usually applied to the surface of a plate material for finishing.

That is, the present invention is based on the fact that the outer peripheral surface of a roll for a roll coater for applying a coating material to a substrate is made uneven, and a non-slip plate having a high anti-slip effect is normally used in a coating process which is usually performed. It is an object of the present invention to provide a method for manufacturing a non-slip plate that can be manufactured without requiring the manufacturing process and can save labor in the manufacturing process.

[0007]

In order to achieve the above-mentioned object, a method of manufacturing a non-slip plate according to the present invention comprises a roll for a roll coater which is in contact with a substrate for a non-slip plate and applies a coating agent to the substrate. The outer peripheral surface is made uneven, and the coating material has a shape-retaining property that maintains the shape of the unevenness when applied to a substrate.

The roll is preferably composed of a roll base and a cylindrical body which is detachable from the roll base and forms the outer peripheral surface.

[0009]

The outer peripheral surface of the roll coater for applying the coating material to the substrate is uneven, and the coating material has a shape-retaining property that maintains the shape of the unevenness when applied to the substrate. The term "shape retention" as used herein means that when the coating material has unevenness and is hardened to form a slip stopper, the unevenness of the unevenness on the outer surface of the roll is transferred to the substrate while maintaining the unevenness. The shape is maintained, but it is acceptable that the unevenness is somewhat collapsed, for example, the height of the unevenness on the outer peripheral surface of the roll is reduced to about 60% on the substrate. Therefore, it is possible to form unevenness on the substrate, enhance the anti-slip effect, and to form the unevenness in the usual coating process, a dedicated line such as rubber sticking or groove processing is required. Therefore, it is possible to reduce labor and labor in the manufacturing process.

As the above-mentioned coating material, abrasion resistance, weather resistance,
A polyester resin coating having excellent corrosion resistance and capable of being supplied at a relatively low cost, and having high viscosity and high shape retention can be suitably adopted.

UV-curable coatings also have good durability and
Since the curing time is short, the energy cost is reduced, and the drying equipment can be downsized with the shortening of the drying time, it can be suitably used as the coating agent.

Further, by forming the roll from a roll base and a cylindrical body which is detachably attached to the roll base and forms the outer peripheral surface, clogging of irregularities due to the coating material adhered to the outer peripheral surface of the cylindrical body. Also in this case, the coating can be easily peeled off by removing the cylindrical body from the roll base, and the maintainability can be improved.
