Description
Technical Field
The invention relates to the technical field of touch control, in particular to a touch control pen point composite material, a touch control pen and a pen point forming method thereof.
Background
With the popularization of touch screens in life and work of people, touch pens with the advantages of high touch precision, rich expanded functions, accordance with the use habits of consumers and the like have gradually become one of mainstream human-computer interaction modes. In order to achieve the user experience closest to that of a pen or a pencil when writing on paper, the nib material needs to be optimally modified and the processing and forming process needs to be adjusted.
Touch tips currently available in the market are generally made of three materials, namely rubber, plastic and fiber felt. In the aspect of writing experience, the rubber touch pen point is soft in texture, and does not have too much noise during writing, but generally has large damping, so that writing is not smooth enough, and fatigue is easy to occur after long-time use; the plastic materials have high hardness, are smooth to write, but are often accompanied by large screen impact sound, and even damage to the screen after long-time use; the fiber felt pen point material can balance screen impact sound and smoothness to a certain extent, and has sharp abnormal sound with certain probability, so that the user experience is poor. Therefore, it is necessary to develop a composite material with excellent comprehensive performance, reduce the writing noise of the pen point, improve the fluency, and obtain the user experience similar to the traditional writing mode.
Disclosure of Invention
Therefore, there is a need for a composite material for a stylus tip, a stylus and a method for forming the stylus tip, so as to reduce writing noise of the stylus tip, improve fluency, and obtain user experience similar to a conventional writing method.
A touch pen tip composite material comprises the following raw material components in parts by weight:
in one embodiment, the ultra-high molecular weight polyethylene has a molecular weight of not less than 150 ten thousand and a particle size mesh number of between 80 and 240 mesh.
In one embodiment, the low density polyethylene has a heat distortion temperature of 40 ℃ to 60 ℃ and a melt index of 1.8g/10min to 2.5g/10 min.
In one embodiment, the lubricant is selected from at least one of graphite powder, polytetrafluoroethylene, and paraffin wax.
In one embodiment, the weight part ratio of the ultra-high molecular weight polyethylene to the low density polyethylene is between 1:1 and 3: 1.
In one embodiment, the weight part ratio of the ultra-high molecular weight polyethylene to the low density polyethylene is 2: 1.

In one embodiment, during sintering and forming, the temperature is slowly increased to 120-200 ℃ according to the temperature increase rate of 1-5 ℃/min, and the temperature is maintained for 60-100 minutes.
In one embodiment, the tip molding method of the stylus pen further includes the step of vacuum drying the ultra-high molecular weight polyethylene, the low density polyethylene, the calcium stearate, the lubricant, the carbon black and the light calcium carbonate before mixing to completely remove moisture.
In one embodiment, the vacuum drying temperature is 70 ℃ to 90 ℃ and the time is 1.5 hours to 2.5 hours.
In one embodiment, during mixing, the ultra-high molecular weight polyethylene, the low density polyethylene, the calcium stearate, the lubricant, the carbon black and the light calcium carbonate are placed in a high-speed mixer to be mixed for 3 to 6 times, wherein the mixing time is 15 to 30 seconds, and the rotating speed is 2000 to 8000 r/min; and adding silicone oil into the mixture, and mixing for 1-3 times according to the same mixing conditions to obtain the uniformly mixed touch pen point composite material.
Research shows that the ultra-high molecular weight polyethylene (UHMWPE) is thermoplastic engineering plastic with excellent comprehensive performance, has small density, good wear resistance, self-lubricating property, impact resistance, corrosion resistance and other properties, but has poor fluidity in a molten state due to the molecular weight of more than 150 ten thousand, and the melt index of the ultrahigh molecular weight polyethylene (UHMWPE) is almost zero, so that the processing performance of the ultrahigh molecular weight polyethylene (UHMWPE) is sharply reduced. Therefore, the pen tip forming method of the present invention adopts a sintering forming method, which is not affected by the poor flow property of the ultra-high molecular weight polyethylene and is not limited by the low molecular weight. Nevertheless, studies have found that the pure ultra-high molecular weight polyethylene touch pen tip prepared by sintering molding still cannot fully meet the special requirements in the field.
Therefore, the components of the touch pen point composite material are further researched and modified, and the prepared pen point is low in noise and high in fluency by adding different components for cooperative matching, and user experience similar to a traditional writing mode can be obtained.
Particularly, the ultra-high molecular weight polyethylene is used as a main body material of the pen point, so that the composite material can be ensured to have excellent overall performance; a certain amount of powdery low-density polyethylene and ultrahigh molecular weight polyethylene are added for matching use, so that the integral hardness of the pen point and the internal pore structure of the pen point can be regulated, and meanwhile, the powdery low-density polyethylene can also reduce the weight of the pen point to a certain extent, thereby weakening the screen impact sound during writing; the silicone oil is added, on one hand, the function of a lubricant can be achieved, the friction factor of the pen point is reduced, the self-lubricating property of the pen point is improved, in addition, as the powdery raw materials of the pen point can generate static electricity in the mixing process, the powder coagulation phenomenon is generated, the filling is not beneficial to the uniform mixing and sintering of the raw materials, the static electricity can be eliminated after the silicone oil is added, and meanwhile, the powdery raw materials are preliminarily wetted, so that the material mixing and the filling are convenient; the addition of calcium stearate can further increase lubrication; the carbon black has stable performance, heat resistance, chemical resistance, light resistance, low cost and strong tinting strength, can be used as a pigment and also has the function of enhancing the conductivity, and when the pen point is used as a multifunctional capacitance pen, the conductivity of the pen point material needs to meet certain requirements; and a small amount of light calcium carbonate is added, so that the weight of the pen point can be further reduced, and the wear resistance of the pen point is improved.

in a specific example, the weight parts of the raw material components are preferably as follows:
wherein, the ultra-high molecular weight polyethylene preferably has a molecular weight of not less than 150 ten thousand and a particle size of 80-240 meshes. The low density polyethylene is preferably a low density polyethylene having a heat distortion temperature of 40 ℃ to 60 ℃ and a melt index of 1.8g/10min to 2.5g/10 min. The lubricant is selected from at least one of graphite powder, polytetrafluoroethylene and paraffin wax. Further, the weight part ratio of the ultra-high molecular weight polyethylene to the low density polyethylene is between 1:1 and 3:1, preferably 2: 1.
In the touch control pen point composite material, the ultra-high molecular weight polyethylene is thermoplastic engineering plastic with excellent comprehensive performance, has low density and good performances such as wear resistance, self-lubrication, impact resistance, corrosion resistance and the like, and can ensure that the composite material has excellent overall performance when being used as a main material of a pen point. The powder low-density polyethylene and the ultrahigh molecular weight polyethylene are matched for use, the integral hardness of the pen point and the internal pore structure of the pen point can be regulated, and meanwhile, the weight of the pen point can be reduced to a certain extent by the powder low-density polyethylene, so that the screen impact sound during writing is weakened. The silicone oil is added to play a role of a lubricant, so that the friction factor of the pen point is reduced, and the self-lubricating property of the pen point is improved; in addition, the powdery raw material of the pen point can generate static electricity in the mixing process, the powder coagulation phenomenon is generated, the raw material is not favorable for uniformly mixing and sintering, the static electricity can be eliminated after the silicone oil is added, and meanwhile, the powder raw material is preliminarily wetted, so that the material mixing and the filling are convenient. The addition of calcium stearate can further increase lubrication. The carbon black has stable performance, heat resistance, chemical resistance, light resistance, low cost and strong tinting strength, can be used as a pigment and also has the function of enhancing the conductivity, and when the pen point is used as a multifunctional capacitance pen, the conductivity of the pen point material needs to meet certain requirements. And a small amount of light calcium carbonate is added, so that the weight of the pen point can be further reduced, and the wear resistance of the pen point is improved.
The invention also provides a touch pen, wherein the pen point is prepared from the touch pen point composite material.
Further, the invention also provides a pen point forming method of the touch pen, which comprises the following steps:
uniformly mixing the raw material components of the touch pen point composite material in proportion;
and (3) putting the uniformly mixed touch pen point composite material into a mold cavity with a preset shape, preliminarily pressurizing through a pressure head, and then sintering and molding.
Preferably, when sintering and forming, the temperature is slowly raised to 120-200 ℃ according to the heating rate of 1-5 ℃/min, and the temperature is kept for 60-100 minutes. For example, in one specific example, the temperature may be raised slowly to 155 ℃ at a rate of 2 ℃/min and held for 90 minutes.
Further preferably, the tip molding method of the stylus pen further includes the step of vacuum drying the ultra-high molecular weight polyethylene, the low density polyethylene, the calcium stearate, the lubricant, the carbon black and the light calcium carbonate to completely remove moisture before mixing. For example, the drying can be carried out in a vacuum environment at 70 ℃ to 90 ℃ for 1.5 hours to 2.5 hours.

The nib is processed by a sintering forming mode, the process control is simpler, and the quality of a finished product is stable. Meanwhile, the nib manufactured by sintering and forming has uneven surface appearance and certain roughness, and the roughness can be adjusted by adjusting sintering temperature and pressure. The proper surface friction coefficient can prevent the damping of the pen point from being too large during writing, and meanwhile, the friction feeling during real writing can be obtained.
