Embodiment 1

[0038] This example provides a method for synthesizing hyperbranched polyamidoamine (used in 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; among them, divinyltriamine and methyl acrylate The molar ratio of ester is 1:1;

[0040] (2) After the reaction, the temperature is increased to 60°C, 100°C, 120°C and 140°C in four stages. In the initial stage (heating up to 60°C, 100°C, the rate of temperature rise can be used empirical values), the vacuum is maintained with a water pump, and the third (The temperature is increased to 120°C, 140°C, and the rate of temperature rise can be empirical) and then use an oil pump. The total reaction time is 24 hours. The hyperbranched polyamidoamine is obtained.

Embodiment 2

[0042] This embodiment provides an indoor air deodorant with sterilization function. The raw material components include hyperbranched polyamidoamine, plant extract, glycol ether, propylene glycol and deionized water, and the weight ratio of each raw material component is: hyperbranched Polyamidoamine accounts for 5%, Sophora 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 sterilization function. The raw material components include hyperbranched polyamidoamine, plant extract, glycol ether, propylene glycol and deionized water, and the weight ratio of each raw material component is: hyperbranched Polyamidoamine accounts for 5%, Sophora flavescens extract accounts for 2.5%, mugwort 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 sterilization function and a preparation method thereof. Background technique [0002] As a sign of the third pollution period, "indoor air pollution" has become a topic of increasing concern. People spend most of their time indoors on average, and indoor air quality directly affects people's health. Surveys have shown that indoor air pollution is often 2-3 times more serious than outdoor air pollution, and in some cases even more than 100 times more serious. Therefore, it is urgent to solve the increasingly prominent indoor air pollution problem. [0003] At present, after the completion of home decoration, various decoration materials, carpets, furniture, fabrics, boards, etc. will emit many harmful pollutants, mainly including formaldehyde, benzene series and other volatile organic compounds (VOCs), accompanied by floating Bacteria and vi...
