Preparation method of comfortable copying pen holder

Abstract

The invention discloses a preparation method of a comfortable copying pen holder. The preparation method comprises the following steps: uniformly mixing ethylene propylene diene monomer and a compounding agent, then adding high-density polyethylene resin and an auxiliary agent into a high-speed mixer, uniformly mixing, extruding and granulating, and finally adding the two materials into a double-component double-flow-channel injection machine, wherein the temperature of a rubber flow channel is 70 DEG C, the length of the rubber flow channel is 0.4m, the temperature of a plastic flow channel is 160 DEG C, the length of the plastic flow channel is 0.5 m, machine heads of the two flow channels are perpendicular to the ground and form an angle of 45 degrees downwards, the two materials are injected into a die cavity of a die with a sawtooth-shaped occlusion structure, the temperature of the die cavity is 150 DEG C, and the forming time is 8 minutes. The preparation method is simple in process and high in production efficiency, and the problems that a traditional pen holder is uncomfortable, not durable, wastes time and the like are solved. The tensile strength of the comfortable copying pen holder reaches 20.8 at least, and the wear resistance reaches 0.14cm < 3 > / 1.61 km.

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...
