Abstract

PROBLEM TO BE SOLVED: To enhance the anti-slip effect of the grip part of a shaft element by forming embossed patterns having specific rubber hardness and specific thickness to at least the grip part of the shaft element by screen printing. SOLUTION: Embossed patterns 2 with rubber hardness of 60-90 and a thickness of 30-200μm are formed to at least the grip part of the shaft element 1 of a writing utensil, a cosmetic utensile or an electronic input pen by screen printing. The surface roughness of the embossed patterns 2 is set to 0.1-3μm and a urethane resin is used as the material quality of the embossed patterns 2. As the material quality of the shaft element 1, a thermoplastic resin such as ABS, PET, POM, nylon or polycarbonate is used and a metal such as aluminum, stainless steel or brass can be also used. Hydrophilic treatment is preliminarily applied to the surface of the shaft element 1 formed of the thermoplastic resin by flame treatment, plasma treatment or corona discharge treatment in order to stably and closely bond the anti-slip patterns 2.

2. Description of the Related Art Conventionally, in order to impart a non-slip function to a grip portion of a shaft, a method of mechanically forming a groove such as a knurl, a method of coating a resin such as silicon which is hard to slip, or A method has been proposed in which a separate member is made of silicone rubber or various elastomers and mounted on the shaft grip portion. The knurling method and the method of mounting another member have already been put to practical use, but the knurling method merely forms a groove on the surface of the shaft body and has no characteristic such as elasticity. There was also a problem that the degree of freedom in design was low. Furthermore, as for the method of attaching another member, the cost is high with a low-priced writing instrument, and there has been a demand for a method that can be accommodated at a low price.

Recently, elastic resin materials and paints have been developed. For example, soft vinyl chloride is extruded and used for a shaft body, or an elastic paint is applied to the whole shaft body or a grip portion to slip. Although methods of giving a stop have been proposed, these methods have a room for improvement because they tend to become slippery due to abrasion of the surface in actual use because the surface is smooth.

Further, as a method of imparting a non-slip function to the grip portion of the shaft body, pattern formation by a screen printing method has been proposed. This method has advantages over the coating method, the transfer method, etc. in that the processing is simple, the pattern shape, and the printing thickness can be arbitrarily selected. That is, in the coating method, it is impossible to form a pattern unless masking is used,
There is a problem that the number of coatings increases when thickening the film to obtain a soft feeling, and the transfer method has a structure of the transfer foil and the resin material for forming the pattern. The thickness tends to be thin, and there is a problem in terms of wear resistance.

By the way, a coating film formed for the purpose of preventing slippage is required to have elasticity and high surface friction resistance. Further, since the anti-slip function is added, if the pattern is peeled off or damaged in actual use, the anti-slip function will be deteriorated. Further, in order to add a non-slip feeling, it is difficult only by elasticity and frictional resistance, and an appropriate feeling of unevenness is required. Therefore, the non-slip pattern
It is essential that the resin has elasticity and unevenness, and is formed of a material having good adhesion to the base material. The screen ink for forming this also needs to have a material and composition capable of obtaining a coating film having high elasticity and adhesiveness. However, when an anti-slip pattern is to be formed on a resin base material, an ink and a treatment method satisfying both of the problems that elasticity is lost when importance is attached to adhesion and that adhesion is not obtained when importance is attached to elasticity are available The current situation is that there are none. Further, when forming a non-slip pattern on a resin substrate, the selection of the screen ink is an important factor because the upper limit of the heating temperature in the process is limited and the pretreatment method and conditions are limited.

The concavo-convex pattern 2 is a non-slip printing portion, and has a rubber hardness of 60 to 90 and a printing thickness of 30 to 20.
0 μm. When the rubber hardness is less than 60, the anti-slip pattern is easily peeled off due to the deformation of the film, and when it exceeds 90, the uneven portion becomes hard and slippery occurs. Further, when the printing thickness is less than 30 μm, the grip of the palm of the finger is reduced and a non-slip feeling is not obtained, and when it exceeds 200 μm, it becomes difficult to maintain the pattern shape and there is a problem in appearance such as foaming. Productivity deteriorates because dots are more likely to occur, skill required for printing is required, and it takes a long time to cure the coating film.

The concavo-convex pattern formed on the grip portion of the shaft according to the present invention is formed by the screen printing method.
The screen plate to be used may be one prepared by a conventional sales process using commercially available sales materials. The emulsion is formed by the intuition method or the emulsion method. The printing thickness can be controlled by appropriately selecting the emulsion thickness and the screen mesh. In particular, the screen mesh is preferably 70 to 150 mesh. If it is less than 70 mesh, the ink tends to drip from the plate, and external problems such as bleeding are likely to occur, and if it exceeds 150 mesh, the ink ejection amount is reduced and it may be difficult to obtain a predetermined print thickness. However, in order to solve this problem, it is necessary to thicken the emulsion, which causes problems such as a problem of plate durability and an increase in plate making cost.

Next, the material of the uneven pattern will be described. As the resin having elasticity, there are silicone resin, various elastomers, urethane resins and the like. However, the silicone resin has a low tear strength, and even if it is made into a screen ink, it cannot be used due to its poor adhesion to the substrate. Further, various elastomers have a problem that it is difficult to make a screen ink and stable printing cannot be performed even if made into ink. Therefore, in the present invention, a urethane resin that is in close contact with the substrate, is easy to form a screen ink, and has excellent printability is particularly preferable. This urethane resin has a rubber hardness of 60 to
90 is good. The urethane resin is a mixture of polyester polyol and polyisocyanate. Particularly, as the urethane resin from which a rubber elastic body is obtained, hexamethylene diisocyanate (HMDI) as polyester polyol and polyisocyanate is used. It is preferable that the organic polyisocyanate used as a raw material is blended. However, since this resin alone has low adhesion to the substrate, it is preferable to add and mix polyester polyol, acrylic polyol, and polyurethane polyol. The amount of addition
10 to 90% by weight is preferred. The reason is 10% by weight
If it is less than 90% by weight, sufficient adhesion cannot be obtained, and if it exceeds 90% by weight, the coating film becomes hard and rubber elasticity may not be obtained.

Next, the surface roughness of the uneven surface will be described. The surface roughness is preferably 0.1 μm to 3 μm, and is 0.1
If it is less than μm, it becomes slippery, and if it exceeds 3 μm, the surface is too rough and the appearance design is deteriorated. As a method of forming this roughness, nylon, polyethylene, polypropylene, polystyrene, acryl, resin powder such as urethane in a screen ink formed of a urethane resin or fine particles obtained by crushing cowhide or silica, alumina, titanium oxide, It may be filled with an inorganic powder such as zirconia oxide, and the concentration thereof may be 2 to 50% by weight based on the solid content of the screen ink resin. The particle size may be about 1 to 50 μm, and the particle shape is amorphous, flaky, spherical, hollow,
It may be fibrous. In particular, the amorphous silica powder has little effect on the color tone of the uneven pattern and can effectively form fine unevenness on the surface of the uneven pattern, but the mechanical strength of the silica powder itself is low. In actual use, since fine irregularities on the surface of the irregular pattern are worn and become slippery, it is preferable to use silica powder having high mechanical strength. As a measure of mechanical strength, it is particularly preferable that the silica powder has a pore size of less than 12 nm and a pore volume of less than 1.6 ml / g. Further, one kind or a mixture of two or more kinds of these powders may be filled in the ink.
