Abstract

The invention discloses a chlorine dioxide bacteriostatic deodorant for a refrigerator and a preparation method of the chlorine dioxide bacteriostatic deodorant. The bacteriostatic deodorant comprisesthe following raw materials in percentages by mass: 0.1-5.0% of a chlorine dioxide precursor, 0.1-5.0% of a gel, 0.01-3.0% of a chelating agent, 0.1-5.0% of a stabilizer, 0.1-3.0% of an activating agent, 0.01-2.0% of a corrosion inhibitor, 0.01-2.0% of a bitterant, 0.01-1.0% of a pigment and the balance of deionized water. The invention further provides a preparation method of the bacteriostaticdeodorant for the refrigerator. The chlorine dioxide bacteriostatic deodorant for the refrigerator is capable of rapidly removing peculiar smell in the refrigerator and inhibiting growth of bacteria,and is safe, environmentally friendly and free of pollution.

Description

technical field [0001] The invention relates to a deodorant and a preparation method thereof, in particular to a chlorine dioxide refrigerator bacteriostasis deodorant and a preparation method thereof. Background technique [0002] With the improvement of living standards, refrigerators are becoming more and more popular. However, during the use of refrigerators, unpleasant smells will be produced inside, which will affect the freshness of food and even affect people's health. The preservation effect of the refrigerator on food is manifested in that its low temperature and freezing environment can inhibit and delay the reproduction and invasion of bacteria, but the bacteria have not been completely killed and still have certain activities. When food is placed in the refrigerator for a long time, bacteria decompose nutrients such as protein, sugar and fat in the food, and produce a large number of low-molecular compounds, such as ammonia, methylamine, hydrogen sulfide and mer...
