Title:
SYNTHESIS PROCESS FOR MACROMOLECULAR BACTERICIDE-POLYOLEFIN CARBAMIDINE
Document Type and Number:
WIPO Patent Application WO/2023/087579
Kind Code:
A1
Abstract:
The present invention relates to a synthesis process for a macromolecular bactericide-polyolefin carbamidine. The technical solution comprises the following steps: 1) adding hexamethylenediamine and ethyl acrylate into a reaction kettle, heating while stirring, and adding an initiator; 2) continuing heating, adding dicyandiamide and guanidine hydrochloride that are uniformly mixed, and dropping hydrochloric acid as a catalyst at a constant temperature; 3) heating multiple times, and performing a constant temperature reaction; 5) after the reaction is completed, dropping clear water into the reaction kettle, and fully stirring; and 6) adjusting the pH value to 6-9 to obtain a polyolefin carbamidine macromolecular bactericide. The present invention has the following beneficial effects: 1) microorganisms in the environment or on the surface of an object can be quickly killed at a relatively low concentration; 2) the product is safe to use because the product does not contain chlorine or heavy metals, and an organic solvent is not included; 3) no harm to the human body is caused when the product stays on the skin surface; 4) unpolluted and safe production is achieved, and waste gas, waste water and waste residues are not produced; and 5) usage is convenient, and a satisfactory usage result can be achieved without requiring a complex compounding process.
