| titleOfInvention | Prefabricated polyurethane foaming elastomer material, preparation method thereof, constructed court and construction method thereof |
| abstract | The invention relates to the field of polyurethane sports fields, in particular to a prefabricated polyurethane foaming elastomer material and a preparation method thereof, a constructed court and a construction method thereof. The prefabricated polyurethane foaming elastomer material is a bi-component foaming polyurethane material and consists of a component A and a component B; wherein the component A consists of polyether polyol, polymer polyol, a foam stabilizer, talcum powder, color green, fumed silica, diethanolammonium, glycol, water and a catalyst; the component B is modified MDI; A. the proportion of the component B is calculated according to the isocyanate index which is 0.7-0.8. The prefabricated polyurethane foaming elastomer material solves the problems of uneven foaming and bulging of a cast-in-place foaming material, and has low water absorption and good cohesiveness; the court constructed by the invention not only solves the problem of poor flatness of the prefabricated court, but also enables the court to have better aging resistance and yellowing resistance. |
