Embodiment 1

[0037] A highly wear-resistant and low-noise plastic nib with conductive filler, such as Figure 1-3 As shown, it includes a nib body 1 arranged at one end of the connecting rod 2, and the nib body 1 has a semicircular structure; the nib body 1 includes a filler body 5, and more than four support bars are welded on the outer wall of the filler body 5. 4. The support bar 4 is made of elastic body material. The outer walls of more than four support bars 4 are welded with the same tightening block 6. The tightening block 6 is a damping material. The other ends of more than four support bars 4 are welded with the same tightening block 6. The fluff layer 3 connects the nib body 1 to the circuit board on the electronic pen through the connecting rod 2. When in use, the fluff layer 3 is in direct contact with the screen, and the support bar 4 at the force point is concave under force, and the force is passed through the tightening block. 6 is close to the surface of the filler body 5...

Embodiment 2

[0046] A kind of production method of the high-abrasion-resistant low-noise plastic nib with conductive filler described in embodiment 1, such as Figure 4 shown, including the following steps:

[0047] S1: Mix 100 parts of polymer monomer material, 1.5 parts of coupling agent coupling agent, 1 part of redox agent, 3 parts of mica powder, and 5 parts of talc powder, and stir at 90°C for 30 minutes to obtain the material;

[0048] S2: Add 11 parts of conductive filler to the material, melt it in an environment of 75°C for 20 minutes, stir and mix, vacuumize to remove air bubbles, and obtain a kneaded product;

[0049] S3: Pour the kneaded material into a circular mold, cool and mold to remove the mold, and obtain the filler body 5;

[0050] S4: after more than four support bars 4 are evenly fixed on the outer surface of the packing body 5, use tightening blocks 6 to fix the middle and lower positions of more than four support bars 4;

[0051] S5: Soak the fluff layer 3 in a s...

Abstract

The invention discloses a high-wear-resistance low-noise plastic pen point with conductive filler and a production method, and relates to the technical field of preparation and application of novel functional polymer materials. The problem that reliability of connection establishment between a pen point and a circuit board is not high is solved. The plastic pen point comprises a pen point body arranged at one end of a connecting rod, and the pen point body is of a semicircular structure; wherein the pen point body comprises a filler body, more than four supporting strips are arranged on the outer wall of the circumference of the filler body, the supporting strips are made of an elastomer material, the same tightening block is arranged on the outer walls of the more than four supporting strips, and the tightening block is made of a damping material. The production method of the plastic pen point comprises the step of mixing 100 parts of polymer monomer material and 1.5 parts of couplingagent coupling agent. When the pen point is used, the fluff layer makes direct contact with a screen, the pen point body reduces writing resistance, improves writing smoothness, reduces fatigue, effectively reduces noise generated when the pen point collides with the screen in the writing process, and protects the screen against abrasion through the combined structure of the inner filler body andthe outer fluff layer.

Description

technical field [0001] The invention relates to the technical field of preparation and application of novel functional polymer materials, in particular to a high wear-resistant and low-noise plastic nib with conductive fillers and a production method. Background technique [0002] Electronic pens are usually used in conjunction with touchpads, tablet computers and other devices. They can not only write characters like a tablet, but also outline images with distinct layers. Since the nib has been writing on the surface of the tablet or notebook screen for a long time, users have high requirements for the surface material of the refill, which must not only meet the friction resistance performance, but also meet the requirements of good conductivity for radio frequency lines. Currently, the popular touch pen nib in the market There are three types of materials: rubber, plastic, and fiber felt. In terms of writing experience, the rubber stylus tip is softer and does not make too...
