SELF-CLEANING, SUSTAINABLE PRODUCT WITH ADDITIVES FROM WASTE TEA FIBERS. COMPOSITE PAINT TECHNICAL FIELD The invention is a sustainable product synthesized from scrap titanium and tea process waste. Obtaining TiO2 raw material of this quality and the antioxidants found in the tea plant. 2 By supplementing with the reducing agent rutin, its photoactivity was increased and under the sun It is related to obtaining nanoparticle-reinforced composite paints with high stability. PREVIOUS TECHNIQUE Paints offer consumers countless decorative options. They are visually appealing. And while it appeals to aesthetics, it also makes the underlying base material both abrasive and corrosive. In this sense, it serves a protective function against external factors. Dust and VOCs (volatile organic compounds) from the environment can contaminate paints due to external factors. organic matter), bad odors, exhaust / greenhouse gases, UV rays, mud rains, Components such as fungi / bacteria etc. accumulate and corrode the paint. This has a negative impact over the years. This accumulation during this time period... The components can form debris or allow bacteria / fungi to multiply on the surface. This causes the paint's chemical composition to change. Environmental conditions as a result of degradation that occurs over a long period of time With this effect, penetration behind the paint begins, and corrosion occurs along with the paint. The underlying material is also damaged. This necessitates renewing the paint layer. This requires. In the literature, in order to prevent this situation, at least partially... Self-cleaning materials have been developed through photocatalytic reactions. TiO₂, 2 Due to its advantages such as low cost and good chemical stability, it is used in many different fields. It is widely and successfully used as a photocatalyst. However, TiO production... 2 generally produced using primary sources and as a result of complex processes In addition, a relatively high photon energy is required for its activation. It is necessary to use dye during the photocatalytic reaction. The stability of its components is also important. 1 THE PURPOSE OF THE INVENTION The aim of the invention is to create a product that can be used in all paints and appeal to all sectors. (powder coating, water-based and solvent-based paint), scrap titanium and an organic component and Sustainable TiO2 raw material synthesized from tea fibers, which are process waste. 2 obtaining and supplementing rutin, an antioxidant and reducing agent found in plants. nanoparticles with enhanced photoactivity and high stability under sunlight. It is related to the production of reinforced composite paint. DETAILED DESCRIPTION OF THE INVENTION The invention was created from scrap titanium and an organic component that arose during tea processing. Sustainable products are synthesized by utilizing tea fibers, which are a process waste. Obtaining TiO raw material and antioxidants and reducing agents found in tea powders. 2 By supplementing with rutin, its photoactivity has been increased and it has high performance in sunlight. It is a method for producing stable nanoparticle-reinforced composite paints; - Tea fibers are broken down into fine particles and their moisture is removed by filtering. being done, - Grinding scrap titanium into powder and reacting it with H₂SO₄, 2 4 - Reacting the titanium solution by adding Na₂PO₄ and... 3 4 then filtered to remove moisture, - The prepared tea waste and Ti (PO₄) are combined and heated. 3 4 4 reacting with NaOH using a magnetic stirrer, - Drying and calcining the resulting recycled TiO nanoparticles. 2 being done, - Steps for mixing calcined TiO₂-NPs into dyes. 2 It includes. The organic waste used in the first step of the method described above is the subject of the invention. These substances are tea fibers that are produced during the sorting stage of the tea processing. These fibers... tea is usually left as waste in tea production facilities for a certain period of time by being exposed to moisture. It is stored and decomposed, then used as fertilizer. More efficient waste management... the process in order to make it more efficient and to produce value-added products TiO₂, synthesized using tea fiber waste and scrap titanium, is added to paints. 2 A new green nanosynthesis that is sustainable and makes reference to recycling, reinforced by reinforcement. 2 The method reveals that waste tea fibers and leaves contain rutin, phosphorus, carbon, and nitrogen. Tea is quite rich in nutrients, especially antioxidants and reducing agents. It is frequently mentioned in the literature that this plant is rich in rutin. The Eastern Black Sea Region, where it is widely found, is both a source of tea and a major producer. It stands out in terms of the locations where its facilities are located. Tea fibers, polymers. Reducing the energy gap of the photocatalytic reaction in base-based paints and achieving high stability. It is reinforced in order to obtain it. Thus, the substances released as a result of the process Sustainable TiO₂ production from waste tea fibers and titanium scrap, which are industrial waste. 2 nanoparticles are obtained. The synthesized TiO₂ can be integrated into different types of paints, thus creating their own unique product. 2 Self-cleaning composite paints are obtained. Surface cleaning and preparation processes of scrap titanium with H₂SO. 2 4 This is done by subjecting the metal to a leaching process for the displacement reaction. It is being activated. Na₂PO₄ is added to the scrap titanium leaching process, which is the next step in organic leaching. 3 4 for displacement and precipitation reaction with tea waste fibers containing the component It is used. ddH₂O is sterile ultra-pure water obtained from materials processed in specific stages. 2 It is used for washing / purifying and solution preparation processes. Reaction of NaOH, extract, and phosphate compound obtained from scrap titanium. It is used to balance the pH level during the process. The details of the procedural steps described above are given below. It has been given. Waste tea fibers with organic components, soil, process residue and The room is washed with ddH₂O sterile ultra-pure water to eliminate microorganisms. 2 It was dried in a shaded area at room temperature. The dried leaves were then ground into a fine powder. It has been ground. 70 grams of ground fiber powder are left in a bottle in 1000 mL of ddH₂O overnight. 2 left to stand for a while and then hot plated at 80°C and 400 rpm for 1 hour. It was placed inside a magnetic stirrer. Filtration was then applied. Scrap metal. Titanium, on the other hand, is dissolved in 96% H₂SO₄ at a rate of 2 g / 100 mL and subjected to leaching. 2 4 It was implemented. The leaching process continued for a full day. Leaching for enrichment purposes. Ultrasonization was performed afterwards. Then 100 mL was added to the solution. It was further diluted by adding ddH₂O. 200 mL of leaching solution prepared with 200 mL of Na₂PO₄. 2 3 4 3 The reaction is carried out using a magnetic stirrer at a speed of 200 rpm for a period of 1 hour. The sedimentation process was carried out by inserting the filtered organic waste. 500 mL of the solution was mixed at 90ºC at a speed of 250 rpm. Add 21.5 grams of the solution obtained from scrap titanium and let it steep for approximately 1.5 – 2 hours. The mixing process continues throughout. The pH value, which is a prerequisite for the reaction, is maintained. To adjust the solution, 1M NaOH was added by dripping from above. This is done. Afterwards, the heating process is stopped and the room cools down to room temperature. The mixing process is continued at 8500 rpm for approximately 15 minutes. Centrifugation is performed at this speed and TiO particles are obtained. This 2 The particles are subjected to a drying and resting phase at 80ºC for 26 hours. Next, the calcination process begins. This takes approximately 3-3.5 hours. The calcination process continues at a temperature of 550ºC. The calcined nanoparticles are sized according to the desired value after size analysis. It can be subjected to a particle size reduction process in the mill. Afterwards, it is processed into powder paint. The paint is ready to apply after a physical mixing process with water or solvent-based paint. is being transformed into this state. 4
