Description of the invention (1) Creation description: The present invention relates to a photocatalyst compound, which is developed through a special manufacturing method. It can be a deodorant that can add photocatalyst titanium oxide to organic substances. . Background of the Invention: The demand for manufacturing a clean living environment has become increasingly strong. In contrast, many products for various purposes have appeared on the market before and after. Among them, catalysts that use light, in addition to not using harmful chemicals, also use nature. Energy decomposes foul odors or polluting substances. In this regard, it will be extremely important in the future. In order to touch the objects, it is necessary to wait for the oxygen light machine. Difficult. The most evil lines are dyed. Titanium is the main source of pollution. The titanium is oxidized and the phase is difficult to be oxygenated. The odor of C is difficult. Health is only added, touched by a product and added titanium light, and it is used. The long-term oxygen knows how to make strong use of permanent touch. The most stink light makes it impossible for exhibitors to upload it as a fruit line. It is expected that in addition to the effect, titanium will become a material more purple, but the hope is touching {deoxygenation, there is a hope that its optical medium is

Description of the invention (2) Detailed description of the invention: The photocatalyst composite of the present invention simultaneously possesses the persistence of the malodorous decomposition of photocatalyst titanium oxide and the special zeolite A fast-acting solution that absorbs malodor, and a porous open-cell capsule made of silicon dioxide is a product of the mixture of the two. The adsorption-type deodorant (special zeolite) used in the present invention refers to an adsorption-type deodorant (special zeolite) with appropriate pore size such as FAU (Faujasite), LTA, MFI, etc., and its pore size is about 1.3nm ~ 3 Between 0 nm, the metal titanium ion (Ti4 +) in titanium tetrachloride (T 1 C) is exchanged with Na + in FAU, LTA, and MFI by ion exchange method: When forming an adsorption deodorant containing titanium, The metal titanium ion (T 1 ") is converted into anatase (titanium dioxide); therefore, the resultant is formed by a hydrothermal method; in order to obtain a photocatalytic effect, the material adsorbed in the crystal is decomposed and discharged; the pore size affects Adsorbed gas molecules, and the gas molecules will diffuse into the holes of the titanium-containing adsorption system deodorant and be adsorbed. The photocatalytic cycle is penetrated by ultraviolet rays (wavelength < 380nm) to achieve long-term use. In addition, opening holes The average particle size of the capsules is 7 to 10 microns, and its schematic diagram is shown in Figure 1. Among them, the photocatalyst titanium oxide uses the energy obtained by ultraviolet irradiation to produce a deodorizing effect. Therefore, it is naturally necessary to obtain the conditions obtained by ultraviolet irradiation. That is to say, the space obtained by sunlight (especially a closed space such as a car) is more suitable. In places where sunlight cannot be irradiated, an ultraviolet irradiation device such as an ultraviolet lamp can be used. As long as this condition is used, it can also be used in Places where windows are not convenient (such as clean rooms, hotels, pachinko stores, underground floors, etc.) Photocatalyst composites disperse them in water-based adhesive resins to form films, or disperse them in olefin-based resins and Laminate or spray, add

Description of the invention (3) Adding synthetic fibers or printing inks, coatings, sprays, etc. are all feasible methods, because the photocatalyst composite is a white powder, so the above application On the whole, it has its coloring and beauty properties.

In addition, the adsorption-type deodorant (special zeolite) of one component of the photocatalyst composite will adsorb odorous substances in the dark, and when the sun or ultraviolet rays are irradiated, the photocatalyst composite has another component of photocatalyst titanium oxide. Active oxygen will be generated and the odorous substances will be continuously decomposed. If only the adsorption-type deodorant is used, its adsorption force will be lost when the adsorption capacity is exceeded. As long as the photocatalyst is not destroyed, the photocatalyst composite will have long-term use. Deodorant effect.

Page 6574074 _Case No. 91124280_Year Month Date__ V. Description of the Invention (4) Examples of the invention: 2 K g of special zeolite (FAU) and 0 · 1 m ο 1 / L tetragasified titanium (T i C 14) Mix 4 ~ 5 L of solution with deionized water and stir at room temperature for 7 ~ 8hr, so that the metal titanium ion (TI1-) in titanium tetrachloride (TiCl4) can be exchanged with Na + in special zeolite (FAU), and Obtain sodium chloride and titanium-containing FAU, then filter through a filter, and wash too much titanium tetrachloride (T 1 C 1 j) solution and sodium vaporized with deionized water. The white powder obtained is then added with 30% hydrogen peroxide ( H2 02) 2 L, deionized water 8 L, left at 6 ° C for 24 hours to hydrolyze the oxygen in the hydrogen peroxide (H202) to hydrolyze the metal titanium ion (Ti 4+) to obtain titanium dioxide (T1 02), followed by 1 0 0 The above liquid was heated at ° C for 8 hours. After cooling at room temperature, it was filtered and washed with deionized water, and then dispersed with a zirconium bead mill. The white liquid obtained was taken out and diluted 10 times with deionized water. spare. When the film is made of resin and photocatalyst compound, the raw materials must be dissolved together and made into small pellets, and then put into the extruder. A total of two external forces must be applied at this time. If it does, the capsule will collapse. As a result, the photocatalyst titanium oxide in the capsule will directly contact the resin and other substances, and the following situations may occur: (1) The resin discolors due to oxidative degradation. (2) Odor is generated by the decomposition of the resin. (3) Degradation of the resin reduces its performance. In order to confirm these matters, in addition to adding a photocatalyst composite only to an olefin-based resin, we also produced an olefin-based resin containing only a photocatalyst titanium oxide and produced two types of films. Regarding the procedure (1), we will change the amount of titanium oxide in the photocatalyst in the two films.

No. 574074 Case No. 91124280 Modification 5. Description of the Invention (5) After adjusting to 3%, the film with the photocatalyst compound will not change color, but the film with the photocatalyst titanium oxide will turn yellow. Regarding the procedure (2), we put the film adjusted by the procedure (1) into a test tube, and irradiated it with ultraviolet (ultraviolet light) for several days, and performed a functional odor inspection. As a result, only the film added with the photocatalyst titanium oxide was emitted. Decomposed stench. Regarding the procedure (3), we added a 5% photocatalyst compound to an olefin resin to make a film (thickness · 40 micrometers), and irradiated with ultraviolet rays to test its elongation. The results are shown in Table 1 and Figure 2. . In addition, after the same film was irradiated with sunlight (placed outdoors), the stretch was measured.

574074 _ Case No. 91124280_ Year Month Day __ V. Description of the invention (6) The results are shown in Table 2 and Figure 3.

From the results of the test stretch, it seems that the degradation of the resin due to the photocatalyst titanium oxide with the destruction of the open-hole capsule is caused by the addition of inorganic substances to make the stretchability low. Hole capsules must have high strength so that the photocatalyst titanium oxide can exist in the hole-opening capsules to prevent the degradation of the resin (organic matter). In addition, although this statement is still speculative, when the photocatalyst composite is actually used, the surrounding There are often low concentrations of odor, and the sorbent in the capsule will first adsorb these odors, and then as shown in Figure 1, the photocatalyst titanium oxide existing around the sorbent in the capsule will be decomposed and absorbed by light irradiation. The odor adsorbed by the binder, and then the active oxygen generated by the photocatalyst titanium oxide will almost fill the entire capsule. It will only decompose the adsorbed odor substance, and will not cause degradation of the resin (organic matter) outside the capsule. From the basic characteristics (adsorption and decomposition) of photocatalyst composites and the above speculations, we will explore how photocatalyst titanium oxide decomposes and is adsorbed. Odor absorbed by the agent. Basic characteristics of the photocatalyst composite of the present invention: Deodorizing performance test: Test standard: Japan JEM 1 46 7.

Measurement object: ammonia (NH3, acetaldehyde (CH3H〇) and acetic acid (CtOOH). Test space: no steel box 1 m X 1 m X 1 m. Test object generation: burn 5 cigarettes at 6 ~ 8 nim Gas concentration measurement: After 2 to 5 nim after the end of combustion, the initial concentration measurement is performed, and they are measured in the order of ammonia (NH3, acetaldehyde (CH3H0), and acetic acid (CL00H)). Illumination conditions: UV 2 54 nm wavelength.

Description of the invention (7) Production of test object: The photocatalyst compound of the present invention is evenly spread on 2 sheets of A4 olefin film and placed in the test space. . The test results obtained are shown in Figures 4, 5 and 6. Under light (ultraviolet) irradiation, adsorption deodorization and deodorization will be performed simultaneously. Because the photocatalyst compound is different from the conventional adsorption deodorant and has the decomposition ability of the catalyst system, it is targeted at high concentrations of odor. It is quite effective. Basically, it is better to irradiate with light (ultraviolet rays) for a long time. The adsorption and decomposition functions of the basic characteristics of the photocatalyst composite are shown in Figure 4.

In addition, even if the light does not irradiate the photocatalyst compound,

Page 10574074 _ Case No. 91124280 _ Month and Day __ V. Description of the invention (8) The adsorbent deodorant (special zeolite) contained in the catalyst compound is used to eliminate odorous substances, as shown in Figure 5. Photocatalyst Comparing the adsorption capacity of the compound with commercially available adsorption deodorants, the effect is not much different, as shown in Figure 5, because it can be used for a long time because of light (ultraviolet) irradiation, which is characterized by continuous repetition Deodorization, but weather and season may affect the conditions such as sunlight and light exposure time, which may cause changes in its deodorization performance and reusability (regeneration function). Photocatalyst composite adsorption regeneration function:

Whether the odor adsorbed by the sorbent is decomposed by the photocatalyst titanium oxide, as shown in Fig. 6, only the photocatalyst titanium oxide is continuous, but lacks fast-acting properties. As shown in Fig. 6, it can be determined that The fast-acting property of the adsorbent can be regenerated by the irradiation of light. In addition, we have also determined that the longer the time of light irradiation, the more fast-acting the adsorbent can be restored. At the same time, the odor adsorbed by the adsorbent will be oxidized by the photocatalyst. Decomposed by titanium, the photocatalyst composite is often exposed to light (ultraviolet rays), and it will also have adsorption and decomposition effects, which is extremely superior in performance. If the sun is actually used, as shown in Figure 6, at night (light is not irradiated) ) Adsorption will be performed, and decomposition and adsorption will be performed during the day (light irradiation), and then adsorption will be performed at night (light irradiation), and this cycle will be repeated for a long time. Photocatalyst composite deodorant performance (continued): We conduct experiments on deodorant effect, and add the photocatalyst composite to form a thin film product (solid ratio: photocatalyst composite 1 g /), binder resin

Page 11574074 _ Case No. 91124280 _ Month and Day __ V. Description of the invention (9) 9 g / m2) Exposure to ultraviolet rays, continuous irradiation to decompose acetic acid, acetaldehyde, ammonia, methyl disulfide, triethylamine And other malodorous substances. In addition, a film made of commercially available activated carbon (solid ratio: activated carbon 1 g / m2, adhesive resin 9g / m2) is used as a control. We add these film samples to a test tube and add A certain amount of odorous substance was irradiated with ultraviolet rays. After a certain period of time, the functional test was performed according to the functional evaluation standard in Table 3. After the evaluation, the odorous substance was added again, and the ultraviolet rays were irradiated. The function is re-evaluated and the operation is repeated. The main evaluation focus is the continuity of the deodorizing effect. The results are shown in Table 4.

The deodorizing performance of the photocatalyst composite can effectively deodorize the aforementioned malodor. In addition, the original activated carbon is superior in its fast-acting or adsorption capacity. However, after a long period of deodorization evaluation, the photocatalyst composite using photocatalyst titanium oxide has a deodorizing effect that exceeds all activated carbons and has a continuous effect. According to this result, we judge that even if the photocatalyst is located in the Kaidong capsule, its performance will not be affected. Photocatalyst composite deodorant performance two:

The foul odors in real life are all compound odors. We implemented deodorization evaluation of cigarette and garlic odor according to the six-stage odor intensity expression method (sm e 1 1 e r test) of Table 5 Environmental Protection Agency's foul prevention method. About the smell of cigarettes: We use olefinic film made of olefinic film (blank) and photocatalyst compound, and use a conical flask with a capacity of 3 5 Om 1 to collect the cigarette lit cigarettes for about ten seconds ◦ 1. Add 0.5 g powdered deodorant, plugged with cork

Page 12 574074 _Case No. 91124280 _ Month and Day __ 5. Description of the invention (10) and shake it gently. 2. Separate the flask with ultraviolet radiation from the flask without ultraviolet radiation, leave it for a certain period of time, and then perform a functional odor inspection. Then repeat these operations. The results are shown in Figure 7. From the results of Figure 7 on the deodorization performance of cigarette odor, in the absence of light, the deodorizing effect is not only small, the film is also dyed yellow. Long-term deodorization effect, the film is not discolored, and the performance is very superior. About the smell of garlic:

We use garlic powder for experiments. With ultraviolet radiation (UV intensity of about 0.2 mW / cm2), 2.0 g of garlic powder was added every 60 minutes, and a functional odor inspection was performed. The results are shown in Fig. 8. From the results shown in Fig. 8, the deodorizing performance of the photocatalyst compound on garlic is superior to powdered activated carbon in the long run. Deodorizing range of photocatalyst compound:

Although many issues remain unconfirmed, if you want to describe the performance of the film containing 5 to 10% of the photocatalyst compound in the olefin resin, the odor of people often smoking in the car, or the odor of new cars, just use the A4 size film can receive the effect in two days, but the deodorization effect will change due to different conditions. If you want to eliminate the unpleasant odor of the room, six tatami-sized rooms (about 2 6 cubic meters) Meters) requires about six A4 size films. Antibacterial effect of photocatalyst compound:

Prepare 10 m 1 in sterilized phosphate buffer. Preparation of the test piece The specimen was cut into a size of 5 cm x 5 cm as a test piece, wiped with an alcohol sponge, and air-dried for testing.

The test operation drips 1 m 1 of the test bacteria liquid on the test surface of the test piece in the plastic plate (Iwaki glass), irradiates it with a fluorescent lamp, and stores it at a temperature of 25 ° C and at a temperature of 30 cm. The light is irradiated at a high level, and the irradiance is about 400 lx. After storage for 24 hours, it is washed with SCDLP culture solution (Japanese pharmaceuticals). The number of bacteria in this washing solution is standardized agar culture solution (Rongken Chemical).

Page 14 574074 _ Case No. 91124280 _ year month day __ V. Description of the invention (12) Mixed release plate culture method (35 ° C for two days) was cultured and measured. The same test was performed with a plastic disk as a control.

The results are shown in Table 6. Under the weak ultraviolet light emitted from the fluorescent lamp, even if the photocatalyst composite is encapsulated by silica, it has almost the same antibacterial power as the photocatalyst titanium oxide, especially for Staphylococcus aureus Significant effect (and we have obtained a result through prior experiments, that is, if only adhesive resin is used and fluorescent light is not used, there is almost no antibacterial effect). In practice, since the photocatalyst composite requires ultraviolet rays from sunlight, etc., the ultraviolet rays strengthen the antibacterial power. In addition to the deodorizing performance, a strong antibacterial effect is expected. Visual changes of photocatalyst complex:

A film made of a photocatalyst compound added to an organic substance (olefin-based resin) due to light irradiation or non-light irradiation. The visual changes caused by light exposure or non-light exposure are placed in A4 size places where the sun is not reachable in the smoking room. One sheet of olefin resin film with photocatalyst compound and one sheet of olefin resin film without photocatalyst compound. The results are shown in Table 7. The film was not exposed to sunlight because it only absorbed the smoke of cigarettes and did not decompose. As a result, if the yellowed film is irradiated with ultraviolet rays for two to three days, it will fade and return to its original function. The following is a few more tests to further verify the present invention: 1. Decomposition of oil pollution: The material obtained in the above examples is evenly spread on marble, and coated with a black oily signature pen (Lion brand), placed outdoors, and exposed to sunlight After irradiation (about 13 hours in Xia Yue period), the black ink completely faded in about three days.
