A kind of high heat-resistant polyurethane composition, polyurethane disc and preparation method thereof |
| abstract |
The present application discloses a high heat-resistant polyurethane composition, comprising a terminal NCO-based polyurethane prepolymer, a modified silica filler, and a curing agent; The polyurethane composition is prepared; the preparation steps of the high heat-resistant polyurethane disc include: cleaning the skeleton, painting the adhesive, drying and placing it in the mold; heating the NCO-based polyurethane prepolymer at the end, and then adding a curing agent and The modified silica filler is evenly mixed and poured onto the surface of the skeleton for molding; the molded polyurethane disk is subjected to post-vulcanization treatment to obtain a high heat-resistant polyurethane disk. The present application has the effect of good wear resistance and heat resistance of the polyurethane disc. |
