| titleOfInvention | Method for preparing polyurethane foam capable of rapidly settling in water |
| abstract | The invention provides a method for preparing polyurethane foam capable of rapidly settling in water, and relates to the technical field of preparation of high polymer materials. The method comprises the following steps: (1) taking 40-80 parts by weight of polyether polyol A, 5-30 parts by weight of polyether polyol B, 5-20 parts by weight of polyether polyol C and 0-20 parts by weight of polymer polyol D, and uniformly stirring; (2) adding 1-6 parts by weight of water, 0.05-3 parts by weight of catalyst, 0.1-2 parts by weight of foam stabilizer and 0-50 parts by weight of filler into 100 parts by weight of the material obtained in the step (1), and uniformly stirring; (3) and (3) adding 30-70 parts by weight of isocyanate E into the mixture obtained in the step (2), stirring, foaming and curing to obtain the polyurethane foam. The polyurethane foam prepared by the method has strong water absorption and retention capacity, can quickly sink to the water bottom and can be repeatedly used in water. |
