Composite material for touch pen nib, pen nib and preparation method

Abstract

The invention discloses a composite material for a touch pen nib, a pen nib and a preparation method, wherein the composite material is capable of promoting the touch sense of a touch pen and is beneficial to protecting a screen and increasing writing input precision. The composite material comprises the following raw materials: 20-80 parts of high-density polyethylene, 20-80 parts of low-densitypolyethylene, 5-25 parts of filler, 0.5-5 parts of silicone powder, 0.5-3 parts of lubricant and 0.5-1.5 parts of dispersing agent. In the composite material for the touch pen nib, high-density polyethylene and low-density polyethylene are uniformly blended at a certain ratio, so that the hardness of end product is reasonably adjusted; when the composite material is used as the pen nib, a certainstrength can be guaranteed, but louder striking sound caused by excessive hardness can be avoided; the composite material is beneficial to protecting the screen and promoting the touch sense while writing.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a composite material for a pen tip of a stylus pen, a pen tip and a preparation method. Background technique [0002] With the popularization of smart touch terminals in people's life and work, touch screens have gradually developed into a complete human-machine interface interaction platform, and people can directly write and input on the screen. Among them, infrared touch technology is the choice of the mainstream market. The advantage of an infrared touch screen is that it can be touched by a finger, a pen, or any object that can block the light to achieve touch operation. From the perspective of touch experience, the stylus has higher precision, richer expansion functions, and is more in line with the user's usage habits, so it has received widespread attention. However, when writing on the screen with infrared stylus tips of different materials and structures, there will be...

AI Technical Summary

Problems solved by technology

Most of the traditional infrared stylus pens have poor touch when writing, and the friction between them and the screen is small and easy to slide, which is not conducive to the improvement of writing input accuracy.

For example, the nibs of high-precision infrared stylus currently on the market are mostly made of POM, silica gel, rubber, fiber and other materials. The nib materials with higher hardness (such as POM) are smooth enough to write and have high mechanical strength, but they are often accompanied by larger screens. Impact sound, long-term use may even cause damage to the screen; although the soft pen tip (such as rubber) has a small impact sound on the screen, it usually has a large damping, and the writing is not smooth enough, which increases the fatigue of the user, and it is difficult to pass the pen tip. Abrasion resistance and drop test; fiber pen tip (such as felt) can balance the impact sound and smoothness of the screen to a certain extent, but there is a certain probability of sharp abnormal noise, and the writing physical examination is poor
