Times New Materials obtained patent for aging-resistant polyurethane elastomer material with low manufacturing cost

On November 17, 2023, according to an announcement from the State Intellectual Property Office, Zhuzhou Times New Material Technology Co., Ltd. obtained a project called "An aging-resistant polyurethane elastomer material and its preparation method." Publication number CN114685744B, patent application date is October 2022.

The patent abstract shows that the present invention provides an aging-resistant polyurethane elastomer material and a preparation method thereof. The preparation raw materials include polyurethane prepolymer, polyol, cross-linking agent and acrylic metal compound; the content of the acrylic metal compound is polyurethane prepolymer. 10‑30% of polymer weight. Polyols are polyols of the same series with different molecular weights, and there are two or more types of polyols. The preparation of elastomer materials includes the following steps: 1) Weigh the polyurethane prepolymer, polyol, cross-linking agent and acrylic metal compound according to the amount, mix and stir the materials evenly; 2) Mix the obtained materials evenly Inject into the mold and solidify to obtain the initial polyurethane elastomer material; 3) The obtained initial polyurethane elastomer material is air-blasted and matured to obtain the finished polyurethane elastomer material. The elastomer material of the present invention has good physical performance and high damping performance; is stable for long-term use and has good aging resistance; the preparation technology is simple to operate and the manufacturing cost is low.
