Composite material for stylus tip, stylus pen and method for forming the tip thereof

Abstract

The invention relates to a touch pen tip composite material, a touch pen and a forming method for the pen tip. The raw materials of the stylus tip composite material include powdered ultra-high molecular weight polyethylene, powdered low-density polyethylene, silicone oil, calcium stearate, lubricant, carbon black and light calcium carbonate. The nib forming method of the present invention adopts a sintering forming method, which is not affected by the poor fluidity of the ultra-high molecular weight polyethylene, and is not limited by the molecular weight. The present invention further researches and modifies the components of the stylus tip composite material, and by adding different components for synergistic cooperation, the resulting pen tip can be made with low noise and high fluency, and can obtain a user-friendly writing method similar to the traditional writing method. experience.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a composite material for a stylus tip, a stylus pen and a method for forming the tip thereof. Background technique [0002] With the popularization of touch screens in people's life and work, the stylus, which has the advantages of high touch precision, rich expansion functions and conformity to consumers' usage habits, has gradually become one of the mainstream human-computer interaction methods. In order to achieve the user experience closest to that of a pen or pencil when writing on paper, it is necessary to optimize the material of the nib and adjust the processing and molding process. [0003] Currently, the popular stylus tips on the market are generally made of three types of materials: rubber, plastic and fiber felt. In terms of writing experience, the rubber stylus tip is soft and does not make too much noise when writing, but usually due to the large damping, the writi...

AI Technical Summary

Problems solved by technology

In terms of writing experience, the rubber stylus tip is soft and does not make too much noise when writing, but usually due to the large damping, the writing is not smooth enough, and it is easy to get tired after long-term use; the plastic material has higher hardness and smooth writing. However, it is often accompanied by a large screen impact sound, which may even cause damage to the screen after long-term use; the fiber felt pen tip material 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 user poor experience
