する方法（特公昭４９−２３５９０ 、特公昭５８３７
２、特公昭６１ − ４０１９６）が提案されている。(Prior art) In general, ink storage tubes for ballpoint pens made of polypropylene resin, the adhesion force between them and the ink for ballpoint pens is greater than the cohesive force of the ink, so ink adheres to the inner wall of the ink storage tube and the ink is The ink is often left on the inner wall of the storage tube, which not only makes it impossible to use up the ink completely, but also makes it impossible to observe the state of ink consumption from the outside. In order to solve this problem, there is a method of applying silicone oil to the inner wall of the ink storage tube (Special Publication No. 49-23590, Japanese Patent Publication No. 5837).
2, Special Publication No. 61-40196) has been proposed.

脂に種々方法で混練し或型する方法も提案された。In addition, for the purpose of improving the ink storage tube, methods have been proposed in which silicone oil or silicone varnish is kneaded with polypropylene resin using various methods to form a certain shape.

いう欠点がある。(Problems to be Solved by the Invention) However, with the method of applying silicone oil to the inner wall of the ink storage tube, it is difficult to form a uniform coating, and at the same time, the molding machine used is expensive. First, it has the drawbacks of extremely difficult die temperature control and poor dimensional accuracy.

できなかった。In addition, the latter improved method of kneading silicone oil etc. into the resin does not allow uniform dispersion, resulting in separation or slipping of the extruder screw, making it impossible to form a film on the inner wall of the intended ink storage tube, making it impractical. However, a sufficient effect could not be obtained.

内壁もインキ反発効果を得ることができた。That is, it is characterized by the use of a silicone powder composition with good fluidity, which is made by highly blending various silicones and polymers with an inorganic support material having a particle size of 3 to 500 μm. The composition of the present invention could be obtained by homogeneously mixing 0.5 to 5 parts by weight of the silicone powder with polypropylene resin, which is an olefin resin, or polyethylene resin. The method of forming an ink storage tube for a ballpoint pen from a ta&lI product is to use an appropriate extrusion device, such as a 40lII/I
1φ (Function) In the ink storage tube for a ballpoint pen made of the composition according to the present invention, a silicone layer was uniformly formed on the entire surface, and the inner wall of the ink storage tube was also able to obtain an ink repelling effect.

付着せず、良好な結果を得ることができた。Comparative Example 100 parts of polypropylene (J9500 manufactured by Mitsui Petrochemical Industries Ltd.) A perfect circular hollow body was obtained by extrusion molding under the same conditions as in Examples 1 and 2. (Effects of the present invention) In order to test the ink repulsion of each ink storage tube of the above-mentioned examples of the present invention and comparative examples, ordinary ballpoint pen ink was used.
The ballpoint pen core is manufactured using the existing ballpoint pen core manufacturing process, and after being exposed to a forced deterioration environment equivalent to 2 years of storage at room temperature, the ballpoint pen tip is removed and the ink storage tube is held vertically to allow the ink to flow down naturally. When observing the ink residual adhesion inside the ink storage tube, it was found that a considerable amount of ink adhered to the inner surface of the ink storage tube without additives made of silicone powder in the ζ-filtration comparison example, but ink remained in the ink of Examples 1 to 3. The inner surface of the storage tube had an ink repelling effect and almost no ink adhered to it, giving good results.
