Embodiment 1

[0034] The preparation of embodiment 1 nylon material

[0035] The formula of nylon material is as follows:

[0036] Monomer caprolactam 10Kg

[0037] Graphite 0.4Kg

[0038] Lithium base grease 0.5Kg

[0039] Bentonite 0.5Kg

[0040] Silane coupling agent 0.2Kg

[0041] Sodium ethylate 0.15kg

[0042] Its preparation method is as follows:

[0043] Monomer caprolactam 10kg, heated to 120°C to melt, and continued to heat to 150°C, added 0.4kg of graphite, 0.5Kg of lithium-based grease. Dry 0.5Kg of bentonite and 0.2Kg of silane coupling agent in advance, and keep it warm for 10 minutes, add 0.15kg of sodium ethoxide, and stir evenly to prepare the raw material of ball-shaped liquid nylon.

Embodiment 2

[0044] Example 2 Preparation of spherical beads

[0045] Nylon filaments are cut into 5-30cm, cut into 0.1-0.8mm balls by round drills, and then cut into balls.

Embodiment 3

[0046] The preparation of embodiment 3 spherical beads

[0047] Nylon slices are melted by a screw extruder and pelletized underwater to form 0.2-1.0mm balls, which are rounded by vibrating drums to form balls.

Abstract

The invention relates to a ball of a ball-point pen, the ball-point pen and a preparation method for the ball. The diameter of the ball of the ball-point pen is 0.1 to 1.2mm, the ball contains 0.1 to 100 weight percent of a nylon material, and the nylon material contains 0 to 20 weight percent of a lubricant. The ball of the ball-point pen is a nylon ball or a ball wrapped with a nylon film, and has the characteristics of wear resistance, corrosion resistance and low friction coefficient. A ball seat body of the ball-point pen is less abraded by the ball, the service life of the product can be prolonged, and writing smoothness can be ensured. Different from an existing inorganic wear-resistant material, organic high polymer nylon has excellent water absorption and ink adhesion characteristics, so that the prepared ball of the ball-point pen has high writing performance.

Description

technical field [0001] The invention relates to the field of ballpoint pen production, in particular to a ballpoint pen ball, a ballpoint pen containing the ballpoint pen, and a preparation method thereof. Background technique [0002] As we all know, a spherical ball is installed on the tip of the writing tool ballpoint pen. Generally, the existing technology is made of stainless steel or other hard materials, which require the ball to have a high surface hardness, wear resistance, and corrosion resistance, and the surface of the existing ball The dense and uniform micropores are easy to absorb ink and do not appear whitening. In order to improve the quality of the balls, technical personnel in the industry have conducted a lot of research on the balls, such as the formation of Fe sulfides disclosed in 00808436.x, and the formation of lubricating properties And wear resistance, vibrating drum polishing, its disadvantages are no microporous ink absorption, high requirements ...
