Embodiment 1

[0040] Weigh 50g of sodium stearate (sodium octadecanoate) and heat to 150°C to melt, and stir evenly. Add 5ml of high-concentration sodium chlorite solution with a concentration of 10% dropwise. After stirring evenly, add 0.1g of oxalic acid to activate it. Add 1ml of essence and 0.1g of food coloring agent to the activated solution in turn, stir well and pour into the mold for cooling.

[0041] Put the prepared sample into 0.125m 3 In the airtight test chamber, drop the formaldehyde concentration to 1.38mg / m 3 , after 90min the concentration of formaldehyde drops to 0.01mg / m 3 .

[0042] With reference to the test method in the patent document CN105145626A to detect the sustained release rate, the results are as follows figure 1 , the results showed that the release rate was greater than 150 μg / h for 64 days.

Embodiment 2

[0044] Weigh 40g of sodium stearate and heat to 150°C to melt and stir evenly. Add 10ml of high-concentration sodium chlorite solution with a concentration of 10% dropwise. After stirring evenly, add 0.25g of citric acid to activate it. Add 2ml of essence and 0.2g of food coloring agent in turn to the activated solution, and stir well. Pour into molds to cool.

[0045] Put the prepared sample into 0.125m 3 In the airtight test chamber, drop the formaldehyde concentration to 1.25mg / m 3 , after 40min the concentration of formaldehyde drops to 0.01mg / m 3 .

[0046] Referring to the test method in the patent document CN105145626A to detect the sustained release rate, the results show that the time for the product release rate to be greater than 150 μg / h is 39 days.

Embodiment 3

[0048]Weigh 50g of sodium stearate and heat to 155°C to melt and stir evenly. Add 7ml of high-concentration sodium chlorite solution with a concentration of 10% dropwise. After stirring evenly, add 0.2g of phosphate to activate it. Add 1ml of essence and 0.1g of food coloring agent in turn to the activated solution, and stir well. Pour into molds to cool.

[0049] Put the prepared sample into 0.125m 3 In the airtight test chamber, drop the formaldehyde concentration to 1.18mg / m 3 , after 60min the concentration of formaldehyde drops to 0.01mg / m 3 .

[0050] Referring to the test method in the patent document CN105145626A to detect the sustained release rate, the results show that the time for the product release rate to be greater than 150 μg / h is 51 days.

Abstract

The invention provides slow-release chlorine dioxide solid soap and a preparation method thereof. The slow-release chlorine dioxide solid soap is prepared by mainly mixing a chlorine dioxide precursor, an activating agent thereof and solid fatty acid salt. The preparation method comprises the following steps: fetching raw materials according to the formula, heating the fatty acid salt to be in a molten state, then mixing with the other raw materials, and cooling to obtain the slow-release chlorine dioxide solid soap. According to the invention, the technical problems that the slow-release chlorine dioxide solid soap is not easy to store or transport and is poor in slow-release effect, the preparation method is complex in process and the like are solved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a slow-release chlorine dioxide solid soap and a preparation method thereof. Background technique [0002] With the acceleration of industrialization level, environmental pollution is becoming more and more serious. The concentration of indoor pollutants is usually 2-5 times that of outdoors, but more than 70% of human time is spent indoors, and the urban population spends more than 90% of their time indoors. Longer, so keeping indoor air clean and removing pollutants in indoor air is of great significance to human health. The methods of indoor pollution control mainly include biological method, physical method and chemical method. The biological method mainly purifies the air through the photosynthesis of plants or the metabolism of microorganisms, but its effect is very small and can only be used as an auxiliary function. The physical method usually uses the adsorption proper...
