Preparation method of anti-skid stationery pen cap

Abstract

The invention discloses a preparation method of an anti-skid stationery pen cap. The preparation method comprises the following steps: step (1) preparing raw materials by weight; step (2) adding hydrogenated styrene-isoprene-styrene block copolymer and paraffin oil into a stirred container with a blender, and processing to obtain a mixture A; step (3) adding homopolymeric polypropylene, ethylene-acrylic copolymer, hydrogenated styrene-butadiene-styrene segmented copolymer, calcium carbonate, silicon-based thermoplastic vulcanized rubber and an antioxidant to the mixture A obtained in the step(2), and stirring uniformly to obtain a mixture B; and step (4) plasticizing the mixture B, extruding and then granulating to obtain the anti-skid stationery pen cap. The anti-skid stationery pen caphas a good anti-skid performance and soft skin touch; and the use of the pen cap on a pen allows a user to write comfortably when the user holds the pen, and the pen cap has a good anti-skid effect.

Description

technical field [0001] The invention specifically relates to a preparation method of an anti-slip stationery pen cover. Background technique [0002] Pens are the most commonly used office and school supplies. Pen manufacturers usually wrap a layer of elastic pen sleeves around the position where the pen holder holds the pen, which not only has an anti-slip effect, but also is more comfortable to hold than pens made of hard materials. By setting a special-shaped soft pen cover, it can also help school-age children quickly grasp the correct posture of holding the pen, and effectively prevent the pen holder from causing excessive extrusion or even deformation of the finger muscles. Commonly used silicon rubber pen covers have poor wear resistance, and after a period of use, the surface will peel and deform, which not only affects the appearance of the pen, but also greatly affects the performance of the pen. As a material that can be processed by injection molding, TPE has th...

Problems solved by technology

The current pen cover is usually based on hydrogenated styrene-butadiene-styrene block copolymer, but the anti-slip performance and skin touch of this TPE type pen cover still need to be further improved
