Embodiment 1

[0029] 1) Prepare Apocynum extract according to the following steps

[0030] a. Soak 800g of fresh apocynum leaves in 1L of ethanol (the amount of fresh apocynum leaves is 80g / 100ml ethanol), let stand for 2 hours, and make A material;

[0031] b. Stir material A in a water bath at 85°C for 10 minutes, then filter, and take the filtrate to obtain material B;

[0032] c. preparing a water-soluble starch aqueous solution with a mass fraction of 20%;

[0033] d. Mix and dilute material B and water-soluble starch aqueous solution at a volume ratio of 2:1 to obtain apocynum extract.

[0034] 2) Preparation of sterilizing solution

[0035] Take 1 part of nano-silver, 4 parts of nano-chitin, 50 parts of apocynum extract, 0.5 part of nonionic surfactant, 1.7 parts of lavender essential oil, and 0.3 part of garlic oil, mix them, and stir them evenly to prepare a bactericidal solution.

[0036] 3) Preparation of aerosol fungicide products

[0037] Put the bactericidal liquid into 24...

Embodiment 2

[0039] The difference from Example 1 is that in this example, when preparing the Apocynum apocynum extract, in step a, the amount of fresh apocynum leaves is 50g / 100ml of ethanol; in step b, the temperature of the water bath is 80°C, and the stirring time is 15min; In step c, in the prepared water-soluble starch aqueous solution, the mass fraction of water-soluble starch is 30%; in step d, the material of B and the water-soluble starch aqueous solution are mixed and diluted according to the volume ratio of 3:1, and the extract of Apocynum apocynum is obtained .

Embodiment 3

[0041]The difference from Example 1 is that in this example, when preparing the Apocynum apocynum extract, in step a, the amount of fresh apocynum leaves is 65g / 100ml of ethanol; in step b, the temperature of the water bath is 90°C, and the stirring time is 10min; In step c, in the water-soluble starch aqueous solution prepared, the mass fraction of water-soluble starch is 25%; in step d, the B material and the water-soluble starch aqueous solution are mixed and diluted according to the volume ratio of 3:1.2, and the apocynum extract is obtained .

Abstract

The invention relates to a compound sterilizing agent for a central air conditioning system. The sterilizing agent is prepared by mixing a sterilizing solution and a propellant, and is filled into anaerosol tank, wherein the sterilizing solution comprises the following raw material components in parts by weight: 1 to 2 parts of nanometer silver, 3 to 4 parts of nanometer chitin, 30 to 50 parts ofan apocynum venetum extract, 0.2 to 0.5 part of a surfactant and 2 to 3 parts of plant essential oil. The compound sterilizing agent for the central air conditioning system provided by the inventionhas the characteristics of good sterilizing effect, long sterilizing validity period and long product shelf life. Inn addition, when in use, the sterilizing agent provided by the invention is sprayedin a form of aerial fog, can penetrate into the interior of the air conditioning system, has the advantage of large sterilization range, thereby further improving the effect of sterilizing.

Description

technical field [0001] The invention relates to a fungicide for a central air-conditioning system, in particular to a compound fungicide for a central air-conditioning system. Background technique [0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the heat load of the indoor environment. [0003] With the continuous growth of the national economy, central air conditioners, as a new type of durable consumer goods, have rapidly entered various large construction sites. In recent years, many families have also chosen central air conditioning. In the central air-conditioning system, bacteria often grow in the drain pipes, a...
