Abstract
The present disclosure provides a water-soluble 1,3-diphenylguanidine (DPG)-based supramolecular inclusion complex and a preparation method and use thereof. A supramolecular compound and a vulcanization accelerator DPG are subjected to supramolecular interaction to form a DPG-based supramolecular inclusion complex. While improving water solubility and dispersibility of the DPG, a molecular structure of the DPG can be completely retained, and the supramolecular host used does not affect a performance of latex. The supramolecular compound and the DPG are ball milled in a certain proportion to prepare the DPG-based supramolecular inclusion complex, the water-soluble DPG-based supramolecular inclusion complex is added in a natural latex curing process; and after mixing evenly, a mixture is foamed on-machine, vulcanized in a steamer, and dried to obtain a latex foam product. The latex product has significantly improved tensile strength and elongation at break, and reduced hardness, which is more healthy and hygienic, showing broad market prospects.
