Description

Method of producing a stain-proofing agent

The present invention relates to the manufacture of an antifouling agent, and more particularly, to prevent contamination by applying to a timely and poorly washed areas such as sleeves or necks of shirts in clothing, and to prevent contamination, The present invention relates to a method for manufacturing a multi-purpose anti-fouling agent that can be sprayed onto a wrapping paper, a wallpaper inside a building, or a site where an aqueous paint is applied to prevent contamination and moisture.

In general, the detergent is a substance that penetrates the contaminated clothing, destroys the contamination, pushes it out of the liquid phase, protects the fiber from contamination, and removes dirt. In other words, detergents are substances that remove and decontaminate the clothing, thereby regenerating and restoring the aesthetic and hygienic functions of the clothing.

These detergents are made from a mixture of chemicals and are available in liquid or powder form. Detergents help water penetrate into clothing, lubricate when worn, and emulsify insoluble matters.

At home, clothes are washed using the same detergent, and according to the type of clothes, different detergents are selected and washed using different washing methods. By the way, if you are washing at home the neck and sleeves of a shirt, or the neck and sleeves of a winter coat, you have to wash your hands with special care to remove them completely. Before putting it into the washing machine, apply soap to the area and rub it with your hands before washing. Therefore, the washing work is cumbersome and often does not fall well.

In addition, when washing at home using a washing machine, in order to increase the cleaning effect on these areas, a large amount of detergent is generally administered, and in this case, the entire clothing may not be rinsed sufficiently to damage the fabric. In addition, it will adversely affect the human body. Therefore, there is a need to develop a material that can prevent the use of detergent by fundamentally preventing the pinching of the neck or sleeve portion of clothing.

On the other hand, in the interior of a building such as a house or apartment, a lot of mold occurs due to moisture in the wallpaper of the room that is hard to light. In order to solve this problem, spraying products for removing mold have been developed in recent years. However, these products are suitable for the prevention of molds that have already occurred, rather than being used in a precautionary manner, and thus are not suitable for application to packaging or textile papers that are easily stored in the room for a long time. Therefore, there is a need to develop a new product that exhibits excellent moisture proof effect.

The present invention has been made to solve the conventional problems and problems as described above, the object of the present invention is to apply to the dirt, such as the sleeve portion or neck of the shirt in the clothing is not well washed and difficult to clean the contamination It is to provide a method for producing a pollution inhibitor which can be prevented.

Another object of the present invention is to provide a method for preparing a pollution inhibitor which can be sprayed onto a wrapping paper of an article which is stored for a long time, a wallpaper or an aqueous paint applied to the inside of a building to prevent contamination and moisture.

In order to achieve the above object, the present invention,

Emulsifying dimethylsilane in ethyl alcohol using nonylphenylamineethylene oxide as an emulsifier (S1);

Preparing a fluororesin emulsion solution by emulsifying the fluororesin in water using a nonionic emulsifier (S2);

A step (S3) of making the first solution by adding the materials produced in the step (S1) and the step (S2) to the mixing tank at the same ratio and sealing the container and reacting the same;

Making a second solution by mixing an acrylic copolymer emulsion having a solid content of 40% with the first solution (S4);

Mixing the second solution with a vinyl acetate emulsion solution having a solid content of 40% and stirring at room temperature (S5); And

After the step (S5), it provides a method for producing an antifouling agent comprising the step (S6) of adding a fatty amine derivative as an antistatic agent and then mixing to make a third solution.

The method for producing the antifouling agent further includes the step (S7) of dropping the temperature of the third solution to 20 ° C. and then adding a predetermined perfume.

Hereinafter, the manufacturing method of the antifouling agent concerning this invention is demonstrated in detail.

In order to prepare the antifouling agent according to the present invention, first, nonylphenylamineethylene oxide is used as an emulsifier to emulsify dimethylsilane into ethyl alcohol. At this time, the volume ratio of dimethylsilane to dimethylnonylphenylamine ethylene oxide is set to 200 to 1, the volume ratio of ethyl alcohol to dimethylsilane is set to 8 to 1, and a physical emulsification method is performed in a reaction chamber equipped with a high speed impeller. Or use ultrasound.

Next, the fluorine resin which is a water / oil repellent agent is emulsified in water using a nonionic emulsifier to prepare a fluorine resin emulsion solution having a solid content of 28%. Preferably, the nonionic emulsifier uses polyoxyethylene.

Through the above process, the emulsion emulsified in alcohol and water are put in the mixing tank in equal proportion, respectively, and the container is sealed, and then the reaction is performed at a temperature of about 60 ° C. Then, crosslinking is formed between the silicon molecule and the fluorine molecule, and a solution having a composition of 800 g of ethyl alcohol, 720 g of pure water, 100 g of dimethylsilicone, and 280 g of a fluororesin solution is made.

Next, an acrylic copolymer emulsion having a solid content of 40% as a film forming aid is mixed with an amount corresponding to 10% of the solution, that is, about 200 g, to form a mixed solution. Then, vinyl acetate having a solid content of 40% is obtained. Emulsion solution is added in an amount corresponding to 10% of the mixed solution and stirred at room temperature for about 3 hours.

After the above reaction is carried out for 5 to 6 hours, aliphatic amine derivative is added as an antistatic agent in a volume ratio of about 0.1% and further mixed.

After dropping the temperature of the solution thus obtained to 20 DEG C, about 115 g corresponding to 5% of the solution was added to the fragrance emulsified in 30% pure water by volume and mixed for another hour. At this time, the fragrance is appropriately added or subtracted in consideration of the temperature of the season in which the product is shipped.

As mentioned above, the anti-fouling agent according to the present invention can be effectively applied to areas where there is a lot of physical contact, such as the neck portion or sleeve portion of the garment, and the washing is not good, so that contamination can be effectively prevented.

In addition, when applied to the wallpaper inside the building, it is possible to effectively suppress the generation of mold and to prevent the generation of moisture. In addition, by spraying on the wrapping paper of the goods to be stored for a long time or the water-based paint coating site inside the building, it is possible to prevent contamination and moisture.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated.
