Description

Technical Field

[0001] The present invention relates to the technical field of mildew inhibitors, and in particular to a mildew inhibitor, a preparation method and application thereof. Background Art

[0002] When a tool kit is in a humid environment for a long time, it is very easy to breed mold, causing the tool kit to become moldy. Once the tool kit is moldy, the mold will cause the tool kit to be easily damaged. At the same time, the moldy tool kit is always in a wet state, causing the iron-based tools in the tool kit to rust, affecting the use of the tools. Therefore, in order to solve the above problems, the tool kit is usually kept dry by sun drying. However, if there is continuous rainy and humid weather, the tool kit cannot be dried in the sun, which will still cause the tool kit to mold.

[0003] In order to solve the above problems, the prior art proposes to use a chemical method to perform mildew-proof treatment on the tool kit. The chemical method mainly uses mildew inhibitors, such as thiocyanate (TCMTB), iodopropynyl n-butylcarbamate (IPBC), etc. At present, traditional mildew inhibitors are mainly emulsifiable concentrate mildew inhibitors, such as a powder mildew inhibitor and a preparation method thereof disclosed in Publication No. CN111117327B. The mildew inhibitor includes n-octylisothiazolinone (DCOIT), IPBC, methyl paraben, ethyl paraben, a dispersant and a stabilizer. The emulsifiable concentrate mildew inhibitor contains a large amount of organic solvents, which are flammable and explosive, have poor safety, seriously pollute the environment, and have high costs. Therefore, relevant technical personnel in this field propose water-based mildew inhibitors, such as a mildew inhibitor and a preparation method and application thereof disclosed in Publication No. CN117918365A. The raw materials of the mildew inhibitor are imazalil, IPBC, an auxiliary agent and water. The mildew inhibitor significantly reduces the amount of organic solvents used, and the mildew inhibitor has a long-lasting antibacterial effect.

[0004] Although the use of chemical mildew inhibitors can prevent products from getting moldy when they are in a humid environment for a long time, in order to ensure that the products are dry, users usually place the products in the sun and high temperature environment for drying when the weather is good. The chemical mildew inhibitors on the products will decompose after being exposed to the sun and high temperature, causing the chemical mildew inhibitors to become ineffective. In addition, in order to ensure the mildew-proof effect of the products, it is necessary to use chemical mildew inhibitors to treat the products multiple times, increasing the cost of mildew-proof treatment. Therefore, improving the high temperature resistance and oxidation resistance of mildew inhibitors is of great significance to reducing the cost of mildew-proof treatment and increasing the effectiveness of mildew inhibitors. Summary of the invention

[0005] In order to overcome the problem that chemical mildew inhibitors in the prior art are easily decomposed after being exposed to high temperature and sunlight, the present invention provides a mildew inhibitor, a preparation method and an application. The main antibacterial substances of the mildew inhibitor are iodopropynyl n-butylamine formate and 2-bromo-2-nitro-1,3-propanediol. The mildew inhibitor is a broad-spectrum antibacterial agent that can kill a variety of fungi and bacteria. When used, the mildew inhibitor can be directly sprayed on the surface of a protected material to achieve a long-term mildew-proof effect.

[0006] The specific technical scheme of the present invention is: A mildew preventer, the raw materials comprising by mass percentage: Iodopropynyl n-butylamine formate 0.1-2%, 2-Bromo-2-nitro-1,3-propanediol 1-10%, Emulsifier 1~15% Solvent Residue.

[0007] Preferably, the emulsifier is one or more of hydrogenated castor oil, sodium dodecylbenzene sulfonate, and polyoxyethylene-polyoxypropylene block copolymer.

[0008] Preferably, the solvent is water.

[0009] Preferably, the raw material further comprises a stabilizer, and the stabilizer is alkenyl zinc bromide.

[0010] Preferably, the mass percentage of the stabilizer is 0.2-0.5%.

[0011] The invention provides a mildew preventer, which is an aqueous mildew preventer. The main antibacterial substances of the mildew preventer are iodopropynyl n-butylamine formate and 2-bromo-2-nitro-1,3-propanediol. The mildew preventer is a broad-spectrum antibacterial agent capable of killing a variety of fungi and bacteria. When used, the mildew preventer can be directly sprayed on the surface of a protected material to achieve a long-term mildew preventive effect.

[0012] In addition, the present invention finds that the mildew inhibitor of the present invention will turn yellow and become ineffective when exposed to sunlight and high temperature. After analysis, it is found that 2-bromo-2-nitro-1,3-propanediol will decompose in an alkaline, high temperature and sunlight environment, thereby causing problems. Usually, in an alkaline environment, 2-bromo-2-nitro-1,3-propanediol mainly undergoes a denitrification reaction, while at high temperature and sunlight, 2-bromo-2-nitro-1,3-propanediol is prone to a debromination reaction. Both of these reactions will cause 2-bromo-2-nitro-1,3-propanediol to decompose and turn yellow. The above problem will cause the mildew inhibitor made of 2-bromo-2-nitro-1,3-propanediol to be very easy to become ineffective in a high temperature and sunlight environment after the product is treated. After analysis, it was found that the main reaction of 2-bromo-2-nitro-1,3-propanediol under high temperature and sunlight is debromination reaction. Therefore, by inhibiting the debromination reaction of 2-bromo-2-nitro-1,3-propanediol, its failure rate under high temperature and sunlight environment can be significantly inhibited, ensuring that the effectiveness time is significantly extended. After research, the present invention found that adding a stabilizer containing zinc ions can significantly inhibit the debromination reaction of 2-bromo-2-nitro-1,3-propanediol. The present invention found that alkenyl zinc bromide has a more significant inhibitory effect on the debromination reaction of 2-bromo-2-nitro-1,3-propanediol. Therefore, after screening, it was found that alkenyl bromide as a stabilizer can significantly inhibit the failure rate of the mildew inhibitor under high temperature and sunlight environment, and improve the effectiveness of the mildew inhibitor under high temperature and sunlight environment.

[0013] A method for preparing the above-mentioned mildew preventer comprises the following steps: iodopropynyl n-butylamine formate, 2-bromo-2-nitro-1,3-propanediol, an emulsifier, a solvent and a stabilizer are uniformly mixed to prepare the mildew preventer.

[0014] An application of the above-mentioned mildew-proof agent in a tool kit comprises the following steps: spraying the tool kit with the mildew-proof agent and drying the tool kit to produce a mildew-proof tool kit.

[0015] Preferably, the conditions for the spray treatment include: a spray volume of 30 to 35 g / m3.

[0016] Preferably, the drying treatment conditions include: a drying temperature of 38-45°C.

[0017] Preferably, the drying treatment conditions also include: a drying time of 30 to 60 seconds.

[0018] Compared with the prior art, this application has the following technical effects: The invention provides a mildew preventer, wherein main antibacterial substances of the mildew preventer are iodopropynyl n-butylamine formate and 2-bromo-2-nitro-1,3-propanediol. The mildew preventer is a broad-spectrum antibacterial agent capable of killing a variety of fungi and bacteria. When used, the mildew preventer can be directly sprayed on the surface of a protected material to achieve a long-term mildew preventive effect.

[0019] The present invention adds a stabilizer to the mildew preventer, and the stabilizer can inhibit the debromination, decomposition and yellowing of 2-bromo-2-nitro-1,3-propanediol in the mildew preventer under high temperature and sunlight environment, thereby improving the stability of the mildew preventer under high temperature and sunlight environment, improving the effect time of the mildew preventer, and reducing the maintenance cost of mildew prevention treatment.

The test results are shown in Table 2; Table 2 Test results As shown in Table 2, after multiple high temperature and light treatments, the tool kits of Examples 1 to 6 will not start to mold until more than 10 treatments have been carried out, and the moldy area will exceed 50% after more than 15 treatments, that is, the mildew inhibitor will not become ineffective until more than 15 treatments have been carried out. However, the tool kits in Comparative Examples 1 to 4 without adding a stabilizer will start to mold after 5 high temperature and light treatments, and the moldy area will exceed 50% after 8 treatments, and the mildew inhibitor will completely become ineffective. The above results show that the addition of a stabilizer can significantly improve the stability of the mildew inhibitor of the present invention after high temperature and sunlight treatment, and improve the timeliness of the mildew inhibitor after high temperature and sunlight treatment. In addition, when the amount of the stabilizer in Comparative Example 5 is too small, the effect of the stabilizer on the mildew inhibitor is weak, and when the amount of the stabilizer in Comparative Example 6 is too large, it will not produce a significant change to the stabilizer.
