Embodiment 1

[0019] Mix EPDM rubber and 43 parts of compounding ingredients evenly, then dry the high-density polyethylene, add it to the extruder, and granulate it through the granulator. Finally, the two components are added to the barrel of the two-component double-channel injection machine. The rubber channel is 0.4 meters long and the temperature is 70 ° C. The plastic channel is 0.5 meters long and the temperature is 160 ° C. Inject into the cavity of a zigzag occlusal mold at a temperature of 150° C., and take out the molded product after the mold is closed for 8 minutes.

Embodiment 2

[0022] The difference between this embodiment and Example 1 is that in Embodiment 2, the length of the rubber flow path is 0.6 meters, the temperature is 100 ° C, the length of the plastic flow path is 0.5 meters, the temperature is 160 ° C, and the temperature is 150 ° C through injection at a 45° angle. In the mold at ℃, the mold is closed for 8 minutes.

Embodiment 3

[0024] The difference between this embodiment and Examples 1-2 is that in Embodiment 3, the length of the rubber flow path is 0.4 meters, the temperature is 70°C, the length of the plastic flow path is 0.3 meters, the temperature is 100°C, and it is injected through a 45° angle head to the temperature For 150 °C mold, mold closed for 8 min.

Abstract

The invention discloses a method for preparing a comfortable copying pen holder. The preparation method comprises: uniformly mixing EPDM rubber and a compounding agent, then adding high-density polyethylene resin and additives into a high-mixer to mix evenly and extruding For granulation, the two materials are finally added to a two-component double-channel injection machine, the temperature of the rubber channel is 70°C, and the length is 0.4 meters. The temperature of the plastic runner is 160°C, and the length is 0.5 meters. The two-runner head is perpendicular to the ground and downward at an angle of 45°. It is injected into the cavity of the zigzag bite structure mold. minute. The invention has the advantages of simple process and high production efficiency, and solves the problems of uncomfortable, undurable and time-wasting traditional pen holders. The minimum tensile strength of the comfortable copying pen holder of the present invention reaches 20.8, and the wear resistance reaches 0.14cm 3 / 1.61km.

Description

technical field [0001] The invention relates to the field of study office stationery, in particular to a method for preparing a comfortable copying pen holder. Background technique [0002] Pen is the stationery that people use most in life. It is a kind of portable stationery. It is widely used because of its convenient use, light weight and low price, which can make people record information or leave marks on any occasion. But when a large amount of text is repeatedly written by hand, long-term writing will cause sore arms and eyes, which will make the mind dizzy and affect work efficiency. Although with the continuous advancement of technology and the continuous development of society, the printing technology that comes with computers can solve such problems well, but there are still a large number of handwriters in the society, and handwriting cannot be replaced. [0003] At present, in order to solve this problem, the most effective way is the pen holder. Most of the p...
