Preparation method of carboxyl-terminated hyperbranched compound activated zinc ion deodorant

Abstract

The invention discloses a preparation method of a carboxyl-terminated hyperbranched compound activated zinc ion deodorant. The preparation method comprises the specific steps: S1, synthesizing waterborne hyperbranched polyester: adding trimethylolpropane and dimethylolpropionic acid into a reactor according to a certain proportion, heating to 150 DEG C, introducing nitrogen for protection, adding a proper amount of a catalyst A, reacting for 3 hours, and then reducing pressure to remove generated moisture; S2, synthesizing a carboxyl-terminated hyperbranched polymer: adding a certain amount of anhydride into the product in the step S1, keeping the temperature at 150 DEG C, reacting for 2 hours, and reducing the temperature to 95 DEG C; S3, carrying out saponification reaction of the carboxyl-terminated hyperbranched polymer and zinc ions: dissolving the product in the step S2 with a certain amount of water, keeping the temperature at 95 DEG C, then adding a certain amount of zinc salt or zinc oxide, continuously stirring for 1 hour, and finally cooling to room temperature and discharging; and S4, cooling to obtain the carboxyl-terminated hyperbranched compound activated zinc ion deodorant. The peculiar smell removing agent synthesized by the method has obviously improved removing effect on peculiar smell molecules.

Description

technical field [0001] The invention belongs to the technical field of indoor deodorization, and in particular relates to a preparation method of a zinc ion deodorant activated by a carboxyl-terminated hyperbranched compound. Background technique [0002] With the development of the economic level and the improvement of the technical level, people have higher and higher requirements for the living environment around them. The air environment is the most important link in the living environment. Being able to breathe fresh air has a very obvious positive effect on people's physiology and psychology. At present, domestic industrial development has experienced extensive development before, focusing on development and neglecting governance, resulting in harmful substances and odors that people are exposed to (oxygen-containing organic compounds such as aldehydes, phenols, alcohols; sulfur compounds such as hydrogen sulfide and sulfur dioxide; ammonia, amines, etc.) Nitrogen co...

Problems solved by technology

At present, domestic industrial development has experienced extensive development before, focusing on development and neglecting governance, resulting in harmful substances and odors that people are exposed to (oxygen-containing organic compounds such as aldehydes, phenols, alcohols; sulfur compounds such as hydrogen sulfide and sulfur dioxide; ammonia, amines, etc.) (such as nitrogen compounds, etc.) is much more likely than before. Long-term exposure to odorous substances will cause great harm to people's nervous system, respiratory system, endocrine system, digestive system, etc., and have a great impact on health.
