Financial news on January 8, 2024, according to the announcement of the State Intellectual Property Office, Hefei Jieshijie New Materials Co., Ltd. has obtained a project entitled "a stone ink whisker filled ABS composition and its preparation method", authorized announcement number CN113061316B, the application date is January 2020.

The patent abstract shows that the invention discloses a stone ink whisker filled ABS composition and a preparation method thereof. The stone ink whisker filled ABS composition is prepared by weight of the following components: ABS 100 parts, ASA 5‑10 parts, polyethylene glycol ether 0.5‑1 parts, stone ink whisker 5‑10 parts, antioxidant 264 ‑2 parts. The invention uses polyethylene glycol ether to treat the stone ink whisker and add it to the ABS composition, which can greatly improve the mechanical properties of the ABS composition. In the preparation process, the ink whisker was first mixed with polyethylene glycol ether, and then other components were added for blending, mainly considering the low melting point of polyethylene glycol ether, close to 60 degrees, and the melting would be uniformly attached to the ink whisker surface when stirred at high speed. In the subsequent extrusion machine melting extrusion, can ensure that the composition melting plasticization uniform, sufficient, excellent performance of the product.
