Abstract

The invention discloses a wear-resistant easy-tinting color cartridge modified material, and belongs to the technical field of high polymer materials. 40-70 parts by weight of polystyrene, 27-45 partsby weight of modified filler, 5-10 parts by weight of silane coupling agent, 1-3 parts by weight of homophthalic anhydride and 2-8 parts by weight of flexibilizer are weighed in sequence, the polystyrene and the silane coupling agent are mixed in a stirrer, the modified filler, the homophthalic anhydride and the flexibilizer are added into the stirrer, under conditions of a temperature of 90-120DEG C and a rotating speed of 250-350 r/min, stirring and mixing are conducted for 30-40 min, then a mixture is obtained, and the mixture is subjected to extrusion and pelleting to obtain the wear-resistant easy-tinting color cartridge modified material. The wear-resistant easy-tinting color cartridge modified material has excellent wear resistance performance.

Description

technical field [0001] The invention discloses a wear-resistant and easy-coloring color pen core modified material, which belongs to the technical field of polymer materials. Background technique [0002] The refill is an accessory of the writing instrument and can be replaced many times. As a writing tool, the pen core is widely used in daily life, study, and office. The general pen core includes a pen core tube and a pen core head. The pen core tube and the pen core head are connected by threads. The pen core tube is equipped with a writing For the liquid used, the head of the refill is equipped with a steel ball. When writing, the liquid in the refill tube slowly flows out through the steel ball at the front end of the refill head to achieve the purpose of writing. [0003] However, in the existing pen core heads, there are usually three or four seats for the steel balls. In actual use, because the seats are too few, the gap between the steel balls and the pen core heads...
