| titleOfInvention | A kind of preparation method of water-resistant high-strength protective material |
| abstract | The invention discloses a preparation method of a water-resistant and high-strength protective material, which relates to the technical field of protective material preparation, and comprises the following preparation steps: 1) drying and dehydrating polyether polyol and polyester polyol; 2) dehydrating polyether polyol, Polyester polyol and foaming agent are mixed to obtain material A; the liquefied diisocyanate is allowed to stand and dry to obtain material B; 3) material B is mixed with material A, foamed, and cured to obtain flexible polyurethane foam; 4 ) The pore wall is pretreated and grafted; 5) The water-resistant polyacrylate emulsion is dipped and coated; the present invention adds polyester polyol when preparing the flexible polyurethane foam, which endows the flexible polyurethane foam with higher mechanical strength At the same time, the pore walls of the flexible polyurethane foam were pretreated and grafted, and then dipped and coated with a water-resistant polyacrylate emulsion, which greatly improved the water resistance. |
