Embodiment 1

[0038] This embodiment provides the method for synthesizing hyperbranched polyamidoamine (for the following examples), and the specific process is as follows:

[0039] (1) Add methyl acrylate to a methanol solution of divinyltriamine with a volume concentration of 35%, and an addition reaction occurs at 0-20° C., and the reaction time is 5 hours; wherein, divinyltriamine and methyl acrylate The molar ratio of ester is 1:1;

[0040] (2) After the reaction is completed, the temperature is raised to 60°C, 100°C, 120°C and 140°C in four stages, among which the initial stage (heating to 60°C, 100°C, the heating rate can use empirical values) stage is used to maintain vacuum, and the third stage (The temperature rises to 120°C and 140°C, and the heating rate can use empirical values) and then replace the oil pump. The total reaction time was 24 hours. That is, hyperbranched polyamidoamine is obtained.

Embodiment 2

[0042] This embodiment provides an indoor air deodorant with bactericidal function. The raw material components include hyperbranched polyamidoamine, plant extract, glycol ether, propylene glycol and deionized water. The weight ratio of each raw material component is: hyperbranched Polyamidoamine accounts for 5%, flavescens extract accounts for 2.5%, wild chrysanthemum extract accounts for 2.5%, propylene glycol n-propyl ether accounts for 5%, propylene glycol n-butyl ether accounts for 5%, propylene glycol accounts for 10%, and deionized water accounts for 70% %.

Embodiment 3

[0044] This embodiment provides an indoor air deodorant with bactericidal function. The raw material components include hyperbranched polyamidoamine, plant extract, glycol ether, propylene glycol and deionized water. The weight ratio of each raw material component is: hyperbranched Polyamidoamine accounts for 5%, flavescens extract accounts for 2.5%, wormwood extract accounts for 2.5%, propylene glycol n-propyl ether accounts for 5%, propylene glycol n-butyl ether accounts for 5%, propylene glycol accounts for 10%, and deionized water accounts for 70% .

Abstract

The invention provides an indoor air deodorant and a preparation method thereof. The indoor air deodorant is prepared from 1-5 parts of plant extract, 2-5 parts of hyperbranched polyamide, 2-10 parts of auxiliary A, 5-10 parts of auxiliary B and 70-90 parts of deionized water, the auxiliary A is dialcohol ether, and the auxiliary B is propylene glycol. Functions that hyperbranched polyamide can chelate ions and adsorb organic small molecules and terminated amino group adsorbs and decomposes formaldehyde are utilized, and the plant extract can effectively attack peculiar-smell ingredients in air, so that the indoor air deodorant has a sterilizing function. The indoor air deodorant is far better than pure formaldehyde removing agent and pure plant-type deodorant in air purifying function, thereby being capable of purifying indoor air more efficiently. The indoor air deodorant has the advantages of being nontoxic, free of irritant gas, free of secondary damage to human body, mild in property, free of corrosion, easy to spray, high in film forming performance and lasting in effect.

Description

technical field [0001] The invention relates to the technical field of air sterilization and deodorization, in particular to a deodorant with bactericidal function and a preparation method thereof. Background technique [0002] As a symbol of the third pollution period, "indoor air pollution" has become a topic that people pay more and more attention to. People spend most of their daily time indoors, and indoor air quality directly affects people's health. According to surveys, indoor air pollution is often 2-3 times worse than outdoor air pollution, and in some cases even up to 100 times more. Therefore, it is urgent to solve the current increasingly prominent indoor air pollution problem. [0003] At present, after home decoration is completed, various decoration materials, carpets, furniture, fabrics, panels, etc. will volatilize many harmful pollutants, mainly including formaldehyde, benzene series and other volatile organic compounds (VOCs), accompanied by floating Bac...
