The invention designs the structure and synthetic formula of the polyurethane gel factor. The gel factor is used to form an organogel in a phthalate plasticizer, and the formulation of soft PVC is prepared by using the phthalate organogel. The present invention proposes to add the gelling factor into the plasticizer, so that the gelling factor self-assembles to form a rod-like, fibrous or sheet-like reinforced structure, and at the same time the plasticizer is gelled, so as to achieve the purpose of enhancing the mechanical properties of PVC, and at the same time, it will not Greatly reduces toughness. The invention relates to the field of polymer material preparation technology and composite material processing technology, in particular to a method for synthesizing a polyurethane organic gel factor and using the organic gel to strengthen soft PVC. |
