Title:
SELF-HEALING ORGANOSILICON POLYMER MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/035192
Kind Code:
A1
Abstract:
A self-healing organosilicon polymer material, and a preparation method therefor and the use thereof, relating to the field of composite materials. The self-healing organosilicon polymer material is obtained by crosslinking and polymerization of at least one reversiblely substituted cyclohexene generated after Diels-Alder reaction on modified polysiloxane A and modified polysiloxane B, wherein the modified polysiloxane A is polysiloxane A substituted by at least one maleimide group, and the modified polysiloxane B is polysiloxane B substituted by at least one furan acetyl group. The organosilicon composite material has good hydrophobic properties, permeability, film forming properties, and reusability; the organosilicon composite material is beneficial to improving the slow-release effect of a fertilizer when applied to a coating material of the chemical fertilizer, has a remarkable advantage in reducing the use amount of the coating material, and has a positive effect on environment protection.
