Description

  The present invention activates oxygen and moisture in air to improve and improve the flammability of internal combustion engines such as automobiles, reduce the concentration of carbon monoxide and nitrogen oxides in exhaust gas, and reduce the amount of particulate matter. The present invention relates to an ionizable functional coating composition and a method for improving the flammability of an internal combustion engine.

  In recent years, as a fuel efficiency improvement device for an internal combustion engine, a technique in which fine powder of tourmaline is individually woven into a fiber and used for a filter of an air cleaner is described in Patent Document 1, and a radiant energy generator is used alone in a pellet form as a fuel. Patent Literature 2 describes a technique used as a combustion method.

  Furthermore, as a combustion efficiency improving device, there is a technology in which a large amount of ore mainly composed of a rare earth metal containing thorium is kneaded alone by at least 50% to form a paint, which is then attached to a filter of an air cleaner in a grid pattern and equipped. It is described in Patent Document 3.

However, in the method using the tourmaline of Patent Document 1 alone, the degree of active ionization of oxygen and moisture in the air is low, and the effect of improving combustion efficiency is low.
Further, since the inventions described in Patent Documents 2 and 3 are technologies that directly use radiant energy, pellets are formed by using an extremely large amount of raw materials, or those obtained by kneading raw materials into a paint by 50% or more are used. It is necessary to attach to the filter of the air cleaner. Therefore, since the air permeability is low, the degree of active ionization is low, and it is difficult to obtain a high combustion effect.

  It is an object of the present invention to provide a functional coating composition having high active ionization and high combustion effect by using a small amount of raw materials and without requiring a troublesome configuration such as mounting an instrument on a filter of an air cleaner. An object of the present invention is to provide a product and a method for improving the flammability of an internal combustion engine using the same.

  The present inventors have reported that a fine powder of tourmaline, a mixed fine powder of zircon raw material sand containing a small amount of a natural radioactive element and a lanthanide rare earth element, and a photocatalytically active titanium dioxide contained in a binder for paints A coating layer was formed on the inner wall of the air intake passage and / or the inner wall of the air cleaner of the internal combustion engine, and a flammability test was conducted. As a result, it was found that the flammability of the internal combustion engine was improved. confirmed.

  It activates the electrolysis reaction of tourmaline by electromagnetic wave excitation of zircon dioxide raw mineral sand containing trace amounts of natural radioactive elements and lanthanide rare earth elements, and further activates hydroxyl radical (.OH) of photocatalytically active titanium dioxide particles. However, it is considered that the synergistic effect of the tourmaline excited by the far-infrared electromagnetic wave is applied to accelerate the generation rate of negative ions with respect to oxygen and moisture in the air, thereby increasing the generation amount.

  Regarding the electric characteristics and far-infrared radiation characteristics of tourmaline, active ionization of water in the air and hydroxyl radical (.OH) activation reaction of photocatalytic titanium dioxide will be described.

Tourmaline has electrical properties and far-infrared radiation properties and active ionizes water. The electrolysis reaction of tourmaline is as shown in “Solid State Physics” Vol. 24, No. 12 (1989).
Electrical properties of tourmaline [Formula ^{_{NaM 2 3 M 3 6 BO 3}} Si 6 O 18 (OH · F) 4] may be a ground fine particles have a special polar crystal called permanent electrode , Each of which is an independent polar crystal, in which one end of both symmetrical poles is a positive electrode and the other side is a negative electrode, and this electrode is a permanent electrode which does not disappear at room temperature.

In the present invention, it is desirable to use a fine powder of iron tourmaline [NaFe ₃ Al ₆ BO ₃ Si ₆ O ₁₈ (OH.F) ₄ ] (98% or less in average particle size of 5 μm or less) as tourmaline. As soon as moisture in the air comes into contact with the fine powder, water (H ₂ O) is dissociated into hydrogen ions (H ⁺ ) and hydroxyl ions (OH ⁻ ), and the hydroxyl ions are hydrated and hydroxyl negative ions (H ₃ O ₂ ⁻ ). Further H ₃ O ₂ ^- changes in oxygen (O ₂₎ of encountering the active hydrocarbon compound is a petroleum component, thought to promote combustion (see Japanese Patent No. 3286307).

  Next, the hydroxyl radical (.OH) surface activity of the photocatalytically active titanium dioxide will be described.

  Although the reaction mechanism of photocatalytically active titanium dioxide is not always clear, it is generally considered as follows (see "How photocatalysis works", Nihon Jitsugyo Shuppan (2000.10)).

Titanium dioxide (TiO ₂ ) absorbs light waves (150 μm or more) such as ultraviolet rays, and electrons (e ⁻ ) and holes (h ⁺ ) are generated inside the titanium dioxide. This is shown in equation (1).
TiO ₂ + λ (electromagnetic wave) → e ⁻ + h ⁺ (1)

The h ⁺ (hole) in the formula (1) reacts with moisture (H ₂ O) in the air to generate a hydroxyl radical (.OH). This is shown in equation (2).
h ⁺ + H ₂ O → OH (OH ⁻ ) + H ⁺ (2)

  The titanium dioxide catalytic reaction formulas shown in the formulas (1) and (2) are reaction formulas using sunlight or ultraviolet rays, but in the present invention, together with the far-infrared radiation energy (electromagnetic wave) of tourmaline, a trace amount of natural Excited by natural radiant energy (electromagnetic waves) of zircon raw material sand containing radioactive elements and lanthanide rare earth elements, moisture in the air generates hydroxyl radicals (OH), which are converted to active oxygen to promote combustion I do.

  In the conventional method, since the electrolytic reaction of tourmaline is weak, the rate of active ionization is low, and the amount of active ions generated is small, the effect of improving the combustion efficiency of the internal combustion engine by using tourmaline alone is low.

  According to the study of the present inventors, as a means for activating the electrolytic reaction of tourmaline, mixed fine powder of tourmaline, desirably iron tourmaline, and zircon dioxide raw mineral sand containing trace amounts of natural radioactive elements and lanthanide rare earth elements And by including photocatalytically active titanium dioxide in the coating composition, in the state of the coating layer, i) the electric properties of tourmaline are excited by the zirconium dioxide raw material sand, and the electrolytic reaction is enhanced; The hydroxyl radical (.OH) activity of photocatalytically active titanium dioxide is increased by the excitation of natural radiant energy (electromagnetic waves) of zircon raw material sand containing infrared radiant energy (electromagnetic waves) and trace amounts of natural radioactive elements and lanthanide rare earth elements. Iii) Synergistic excitation of tourmaline and photocatalytic titanium dioxide accelerates the active ionization rate. It was found to increase the amount of generated ions.

The present invention provides a photocatalytically active titanium dioxide, in which the hydroxyl radical surface activity is not light energy such as sunlight or ultraviolet rays, but far-infrared radiation energy of tourmaline, and a zircon dioxide raw material sand containing a natural radioactive element and a lanthanide rare earth element. Was excited by natural radiant energy (electromagnetic waves). As a result, the active ionization rate can be increased to increase the amount of generated ions, and the improvement in the combustion effect of the internal combustion engine has been solved. Thus, the present invention has been completed.

  Active ionization of oxygen in the air includes active ionization of oxygen by corona discharge and high-voltage discharge by ozone generation.The active ionization of oxygen in air of the present invention is based on trace amounts of natural radioactive elements and lanthanides. It is considered that the natural radiant energy (electromagnetic wave) of zircon dioxide raw mineral sand containing rare earth elements excites oxygen in the air and converts it into active oxygen, generating a large amount of active oxygen and promoting combustion.

  The present invention provides a functional coating composition that converts oxygen in the air into active oxygen by a synergistic excitation action of the tourmaline and photocatalytically active titanium dioxide, and actively ionizes oxygen and moisture in the air, and An object of the present invention is to provide a method for improving the flammability of an internal combustion engine used.

The components of the zircon dioxide raw mineral sand containing a trace amount of a natural radioactive element and a lanthanide rare earth element according to the present invention are ZrO ₂ , TiO ₂ , Al ₂ O ₃ , P ₂ O ₅ , SiO ₂ , Fe ₂ O ₃ , La ₂ O ₃ , CeO ₂ , CaO, Nd ₂ O ₃ , Pr ₆ O ₁₁ , Y ₂ O ₃ , K ₂ O, Cd ₂ O _3, Sm ₂ O ₃ , MoO ₃ , and other trace amounts of natural It contains thorium oxide (ThO ₂ ), which is a radioactive element. Among these, the composition (weight composition ratio) of the main components is as follows. _{Fe 2 O 3 20~30%, CeO} 2, P 2 O 5, SiO 2 10~20%, La 2 O 3, Nd 2 O 3, ZrO 2, TiO 2, Al 2 O 3, CaO 2~10% , ThO ₂ 1-6% (preferably 2-5%).
In addition, the natural radiation concentration (electromagnetic wave) of the above zircon dioxide raw material sand is below the safety standard value instructed by the Ministry of Education, Culture, Sports, Science and Technology, and it is confirmed by use of the Tokyo Metropolitan Industrial Technology Center that it is safe to use. .

  By forming a coating layer using the functional coating composition of the present invention, oxygen and moisture in the air come into contact with the surface of the layer to be activated and ionized, and the generation rate and the generation amount of the activated ions increase, and combustion occurs. It is possible to enhance the nature. Since sufficient propulsion is exhibited by reducing fuel consumption and complete combustion of petroleum components is performed, remarkable improvement in flammability is achieved, and the effect is great.

An embodiment of the present invention will be described.
The functional coating composition for improving and improving the flammability of an internal combustion engine according to the present invention comprises 1 to 20% by weight (preferably 3 to 10% by weight) of fine powder of tourmaline and a lanthanide rare earth element which is a trace amount of a natural radioactive element. 1 to 40 parts by weight (preferably 10 to 40 parts by weight) of mixed fine powder with 99 to 80% by weight of zircon raw material sand containing zirconium, and 1 to 15 parts by weight (preferably 5 to 15 parts by weight) of titanium dioxide having photocatalytic activity And 100 parts by weight of a paint binder to form a coating layer on the inner wall of the air introduction passage and / or the inner wall of the air cleaner of the internal combustion engine.

In forming the coating layer, it is desirable to apply the functional coating composition directly to the inner wall of the air introduction path and / or the inner wall of the air cleaner of the internal combustion engine. However, it is preferable that the functional coating composition is supported on an aluminum foil or the like or on another medium. Is also good.
Then, by inhaling a predetermined amount of air, oxygen and moisture in the air come into contact with the surface of the coating layer of the functional coating composition and are immediately converted into a large amount of active oxygen.

  In the present invention, the amount of the mixed fine powder necessary for active ionization of oxygen and moisture in the air may be 1 to 40 parts by weight based on 100 parts by weight of the binder for a coating material.

  The zircon dioxide raw mineral sand containing a trace amount of a natural radioactive element and a lanthanide rare earth element activates the electrical properties of tourmaline and promotes the photoactivity of photocatalytically active titanium dioxide. As a result, oxygen in the air is activated into ions, and the generation of active oxygen is promoted to increase the generation amount.

  The far-infrared radiation energy of tourmaline promotes active ionization of water, and creates a state in the coating layer where fine particles of tourmaline do not contact each other in order to increase the rate of ion generation and increase the amount of generation. It is necessary. Therefore, photocatalytically active titanium dioxide is also added for this purpose.

  The photocatalytically active titanium dioxide used in the present invention is not limited to a crystalline type, but anatase type, amorphous type, brookite type, rutile type titanium dioxide is used, and the particle size is 0.0001 to 0.001. 2 microns are preferred. In these photocatalysts, metals such as platinum, rhodium, ruthenium, silver, copper, and zinc may be supported on the surface.

As the binder resin of the coating composition of the present invention, resins such as natural rubber latex, acrylic resin, silicone resin, silicone rubber, latex, epoxy vinyl acetate resin, epoxy resin, and acrylic fluorine resin can be used. Resins are preferred.
Further, these resins are desirably applied as a binder of an aqueous paint or an aqueous resin emulsion.

  In the case of an aqueous resin emulsion, since the diluent is water, there is less risk of fire as compared with an organic solvent, and it has low toxicity, has no unpleasant odor like an organic solvent, and dries quickly. Suitable resins include a vinyl acetate emulsion such as an ethylene-vinyl acetate copolymer and a vinyl chloride-vinyl acetate copolymer, a styrene-butadiene emulsion, and an acrylic emulsion. Used as

Further, as the coating composition of the present invention, additives which are usually added to coatings, for example, pigments, viscosity modifiers, leveling agents, anti-settling agents, plasticizers, surfactants, rust inhibitors and the like can be added at an arbitrary ratio. .
Further, the paint of the present invention can be widely applied as an oil-based paint, an alcoholic paint, and a cellulose paint in addition to the water-based paint.
Hereinafter, the present invention will be described with reference to examples.

On a test course (Fuji Speedway), an actual vehicle running test was conducted.
Table 1 shows the results of comparative experiments in which the average speed was 60 km / h and the speed was 80 km / h, and the vehicle ran 200 km each.
The weather on the test day was sunny, the temperature was 22 degrees Celsius, and the wind speed was 3.8 meters.
Before conducting the test, all the gasoline was drained from the gasoline tank of the experimental car, and the test was carried out by emptying the tank and adding a fixed amount of gasoline in 50 L increments. At the end of the test, the fuel was drained again and the remaining amount was accurately measured. . The procedure and conditions at that time are as follows.

1. The test before coating the functional paint composition was carried out on two models: Toyota Crown (2500 cc), 1999 type, display of 25,300 km, and Daihatsu Charade (1600 cc), 1995 type, display of 52,870 km.
2. Tourmaline fine powder 10% by weight, 40% by weight of a mixed fine powder of 90% by weight of zircon dioxide raw material sand containing a small amount of natural radioactive element and lanthanide rare earth element, 15% by weight of photocatalytically active titanium dioxide, acrylic resin emulsion (solid (30% in water, 70% in water) 100 g of a functional coating composition containing 100 parts by weight of the coating composition was applied to 0.05 m / m of aluminum foil in an amount of 220 g per m ² , and the coated layer was mounted on an air cleaner box. .
3. For mounting the aluminum foil coated with the functional paint composition, the air cleaner (made of paper) is once taken out, and the aluminum foil is put on the inner wall of the air suction passage and the inner wall of the air cleaner box in a total area of 0.402 m ² and 0.458 m ^2. Was attached. Thereafter, the test after coating the functional coating composition was similarly performed.
4. The amount of negative ions generated from the aluminum foil was measured. As a result, 4050 negative ions were generated per cm ³ . SC-50 manufactured by Sigma-Tech Co., Ltd. was used as a measuring instrument for measuring the amount of generated negative ions.
The reason for using an aluminum foil with a coating layer formed of a functional paint composition was to conduct a comparative test under the same conditions, that is, to change the presence or absence of the coating layer on the same surface area, the same car, etc. To change the amount of generated negative ions.
5. The same effect was obtained when the functional coating composition was directly applied to the inner wall of the air suction passage and the inner wall of the air cleaner to form a coating layer.

10 parts by weight of a mixed powder of 3% by weight of fine powder of tourmaline, 97% by weight of zircon dioxide raw material sand containing trace amounts of natural radioactive elements and lanthanide rare earth elements, 5 parts by weight of photocatalytically active titanium dioxide, and acrylic resin A functional coating composition containing 100 parts by weight of an emulsion (solid content 30%, water content 70%) was prepared. The paint was applied to a surface of 0.05 m / m aluminum foil with a spray gun at 220 g / m ² to form a coating layer.

Using this aluminum foil, it was attached to and adhered to a total area of 0.405 m ^{2 of the} inner wall of the air intake passage and the inner wall of the air cleaner of a gasoline vehicle (Nissan Skyline 2000 cc). As a result of measuring the surface of the aluminum foil on which the coating layer was formed, generation of 4,500 negative ions per 1 cm ³ was confirmed.
The measurement of the amount of generated negative ions was performed using an ion meter SC-50 manufactured by Sigma-Tech Corporation.

  A comparative test was carried out using the above-described test vehicle in which an aluminum foil having a coating layer was stuck to and adhered to the inner wall of the air suction passage and the inner wall of the air cleaner.

As a result of traveling 200 km at an average speed of 90 km / h (80 to 100 km / h), 24.5 L of gasoline was consumed, and the fuel consumption was 8.15 km / L.
On the other hand, in a comparative test without a coating layer, the vehicle traveled 200 km at an average speed of 90 km / h, but gasoline consumed 34.5 L and fuel consumption was 5.8 km / L. .

[Comparative example]
Table 2 shows the results of a comparative test for clarifying the difference in the effect depending on the presence or absence of tourmaline, excitable material (zirconite sand), and photocatalyst.

Using a comparative paint “ratio 1- (3)” (amount of negative ions generated: 720 / cm ³ ), a spray gun was used to spray 200 to 230 g / m ^{2 on} 0.05 m / m aluminum foil according to Example 1. Was uniformly sprayed to form a coating layer. Using the engine used in Example 2, the inner wall of the air suction passage and the inner wall of the air cleaner were replaced with a total area of 0.405 m ² .
According to the embodiment, an actual vehicle test was performed at an average speed of 100 km / h. As a result, the fuel consumption was 5.80 km / L before coating and 6.06 km / L after coating. The effect of improving flammability was slight, and no remarkable improvement was observed.

It was mixed with 100 parts by weight of an emulsion (solid content 25%, water content 75%) to prepare a coating material A and a coating material B as functional coating compositions. The paint was applied to a cotton cloth by a spray gun at 260 to 280 g / m ² to prepare two types of coated cotton cloths A and B, respectively.

As a result of measuring the negative ions for each of the coated cotton cloths A and B, the coated cotton cloth A measured 2500 negative ions generated per 1 cm ³ . In addition, the amount of generated negative ions of 4500 pieces per 1 cm ^{3 of the} applied cotton cloth B was measured.
Using the coated cotton cloths A and B, 0.54 m ² equivalent was stuck to the inner wall of the air suction passage and the inner wall of the air cleaner of a private car (Toyota Cresta 3000 cc), and closely attached. When using the coated cotton cloth B, A was peeled off and replaced, and the test was performed after replacing the cloth.

  In the test for confirming the flammability improvement effect, the vehicle traveled 200 km each at an average speed of 50, 80, 100, 120, 140 and 150 km / h, and the distance traveled per liter of gasoline was converted and compared. FIG. 1 shows the results of the implementation test.

As a result of the test, the fuel consumption before application (when not used) was about 8 km per liter. At running speeds of 50, 80, 100 and 130 km / h, there was no significant change.
On the other hand, when the applied cotton cloth A is mounted on the inner wall of the air cleaner, the fuel consumption is 8.8 km per liter at 50 km / h, 9.5 km at 100 km / h, and the highest of 10.2 km at 130 km / h. And the combustion efficiency improved by up to 27.5%.

At 0 km and 150 km / h, it was 9.2 km, and at 120 km / h, the fuel consumption improvement rate was the maximum, and the combustion efficiency was improved.

The aluminum foil having the coating layer used in Example 1 was attached to an inner wall of an air suction passage of an Nissan diesel vehicle (10 t truck) and an inner wall of an air cleaner so as to have a total area of 0.95 m ² .
A fuel consumption test was performed on the diesel vehicle at a distance of 100 km at 80 km (70 to 90 km / h) using light oil. As a result, the fuel consumption was 4.5 km / L before coating and 5.8 km / L after coating.
