Dirt isolation water repellent with preventive cleaning effect

The present invention relates to a soil release water repellent having a preventive cleaning effect, in particular to a water repellent agent capable of forming a non-polar interface on the surface of a plurality of objects, mainly by using a preventive cleaning effect. Isolation water-repellent is applied to the surface of a plurality of objects to form a non-polar interface with hydrophobic properties, which effectively prevents water stains from remaining on the non-polar interface, so as to isolate dirt and reduce its adhesion to the surface of the object and easy to clean. The advantage.

According to the continuous improvement of living standards and the accelerating pace of life, people are more relaxed, convenient, time-saving and labor-saving for home cleaning work, especially the current cleaning work at home often requires many cleaning tools. For example, cleaning tools such as brooms, mops, brushes or rags can make cleaning at home easier and less laborious. In addition, home cleaning needs to be combined with a variety of chemical cleaners to achieve strength. Decontaminated home cleaning purposes, and save time and effort and twice the result with half the effort.

The traditional cleaning method is mainly when the dirt adheres to the surface of the object, as long as the traditional corrosive chemical cleaning agent is sprayed on the surface of the dirt-attached object, and then brushed with a cleaning tool such as a brush, a melon cloth or a rag, The foam formed by the chemical detergent mixes the water to remove the dirt from the surface of the object for cleaning purposes; however, the cleaning tools such as brushes or melon cloth used in the conventional cleaning method are easy to be in the object (for example, ceramics or metal products, etc.) ) the surface is left with scratches to make the subsequent dirt Easy to be stuck in the scratched seam, it is not easy to clean, it looks like it is not cleaned, and it has the disadvantage of half the work. In addition, if the surface is attached with too much dirt, it will make the cleaning process time-consuming and laborious and corrosive. Sexual chemical cleaners also have the disadvantage of easily damaging the skin of the hands of cleaning personnel; therefore, how to effectively meet the needs of busy modern people, make cleaning work easy, convenient, time-saving and labor-saving, and still effectively extend home The cleanliness of the environment is still a subject that developers and related academic units in cleaning companies need to overcome and solve.

Nowadays, the inventor is in view of the above-mentioned traditional cleaning method, which makes the cleaning staff time-consuming and laborious, and the cleanliness of the surface of the object is not easy to maintain for a long time, and so on, so it is a tireless spirit, and with its rich professional knowledge and many years The practical experience is supplemented and improved, and the present invention has been developed based on this.

The main object of the present invention is to provide a soil release water repellent having a preventive cleaning effect, in particular to a water repellent agent capable of forming a non-polar interface on the surface of a plurality of objects, mainly by having a preventive cleaning effect.

In addition, in a preferred embodiment of the present invention, the soil release water repellent having a preventive cleaning effect hydrolyzes the hydrochloric acid component by decane to make the reaction pH value acidic, accelerate the hydrolysis rate of the decane, and then Dibutyltin dilaurate (DBTDL) catalyzes the polymerization of decane and hydrogen-terminated polydimethyloxane.

Next, in order to enable the reviewing committee to further understand the object, features, and desired effects of the present invention, the specific practical embodiment of the soil separating water repellent having the preventive cleaning effect of the present invention is further exemplified. The scope of the present invention is not intended to be limited in any way; first, the hydrochloric acid-type decane formulation according to an embodiment of the present invention is composed of 10 wt.% of hydrogen-based terminal polydimethyl oxane ( OH-PDMS-OH), 2.4 wt.% tetraethoxy decane (TEOS), 2.3 wt.% methyltrimethyl decane (MTMS), 0.5 wt.% dibutyltin dilaurate (DBTDL), And 84.8 wt.% and a concentration of 95% of isopropanol (IPA) are mixed, and since the mixed solution is further fine-tuned with a pH of 4 by methyltrichlorosilane (MTCS), there is no need to add Hydrochloric acid can accelerate the hydrolysis of decane; and subsequently, the soil release water repellent having the preventive cleaning effect of the present invention is applied to the surface of a plurality of objects to be cleaned, wherein the materials are, for example, ceramics for kitchen bathrooms. Articles, clothing, umbrellas, textiles, not Steel sheet of metal items, automotive sheet items are gold paint, acrylic plastic items, the items are rock marble flooring, furniture, home When the dirt-repellent water-repellent agent having the preventive cleaning effect of the present invention is applied to the surface of the object, the water-like article or the paper-based toilet paper of the present invention can be confirmed by the contact angle test of the water drop. The contact angle of the surface of each material may be greater than 90 degrees, that is, the surface of the object of different materials is coated with the dirt-repellent water-repellent having the preventive cleaning effect of the invention and allowed to stand for one day to test the water droplet size of 10 μL. The water droplet contact angle test is carried out under the conditions. The experimental results are as shown in the following table. After the surface of the plurality of materials is coated with the soil release water repellent having the preventive cleaning effect of the invention, the contact angle of the water droplets on the surface is greater than 90 degrees. This means that the soil release water repellent having the preventive cleaning effect of the present invention can effectively change the surface properties of various objects into hydrophobic characteristics; in addition, when the surface of the object gradually tilts, the surface of the surface adheres to flow and the surface of the object is tilted. The angle, which is the minimum angle that can be applied when moisture is not affected by the material properties.

In addition, the dirt separation water repellent agent having the preventive cleaning effect of the invention can be Long-term coating on the surface of the coated object to effectively extend the cleaning effect of the water-repellent agent on the surface of the object; from the test data in the following table, it is also tested in the test of the contact angle of water droplets under the test conditions of measuring the water droplet size of 10 μL. The average contact angle of the water droplets is greater than the standard value of 90 degrees in the test time from the start of the application to the end of the test at 2280 hours, whether on the surface of the glass slide or the surface of the ceramic tile. As a result of the final test, the soil release water repellent having the preventive cleaning effect of the present invention can be effectively coated on the surface of the object in the application time of 2280 hours (i.e., 95 days) (the contact angle of the water droplet is about 105). Degree), to achieve the cleaning effect of extending the surface of the object, to achieve the advantage of bright and clean surface of the object.

Furthermore, when the soil release water repellent having the preventive cleaning effect of the present invention is applied to the surface of the object to be cleaned, a non-polar interface having a hydrophobic property can be formed on the surface of the object, and the cleaning personnel only need to rinse with water. Covering the surface of an object with a non-polar interface, the effect of moisture not easily adhering to the non-polar interface can effectively remove the dirt from the water, thereby reducing the residual water stain, the moisture is not easily adhered, and the cleaning is easy. The characteristic is effective to extend the cleaning effect of the surface of the object, and the advantage of the surface of the object is bright and clean.
