Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and particularly to a negative oxygen ion spray. Through innovative formulation design, this product achieves the persistent release of small-sized and high-concentration negative oxygen ions, and has triple effects of air purification, antibacterial disinfection and health promotion, and is applicable to various enclosed environments such as homes, offices, medical institutions, vehicles, etc. Background Art

[0002] Negative oxygen ions can make the micron-sized dust that is invisible to the naked eye and belongs to positive ions, formaldehyde, coke smoke, second-hand smoke, and cooking fumes in the air form molecular clusters through attraction and collision with negative oxygen ions, and sink to the ground, playing a role in purifying the air. Negative oxygen ions can make the two poles of bacterial proteins reverse, thus reducing the survival ability of bacteria. Negative oxygen ions can purify the air quickly and efficiently, and have an effect on microorganisms, bacteria, and viruses on the air and the surface of objects. People need a large amount of negative oxygen ions every day, but the environments of our living rooms, offices and other places can only provide a small amount of negative oxygen ions, which is easy to make people fatigued, and it is easy to get urban diseases and air-conditioning diseases in the long term, making the human body in a sub-healthy state. After inhaling high-concentration negative oxygen ions, it can increase the oxygen absorption amount of the lungs and discharge more carbon dioxide. It has a certain effect of relieving mental stress, making people excited and improving work efficiency. When negative oxygen ions enter the blood, they can slow down the sedimentation of red blood cells, prolong the coagulation time, effectively reduce the aggregation of red blood cells, lower the blood viscosity, and also increase the content of blood red blood cells and blood calcium, and decrease blood sugar. After negative oxygen ions enter the body, they can promote metabolism, improve the body and enhance the disease resistance. Air negative oxygen ions can relieve allergic pollen fever, bronchial asthma, upper respiratory tract catarrh, etc.

[0003] In nature, certain plants (such as pine, cypress, fir, etc.) and natural minerals (such as tourmaline, opal, ancient sea salt, etc.) can release negative oxygen ions. These minerals have a nano-microporous structure, are rich in various trace elements such as germanium, titanium, selenium, zinc, etc., and the micro-pore potential difference can decompose water molecules to generate negative ions. At present, negative ion functional materials have been widely used in the fields of air purification, textiles, building materials, etc. However, in the prior art, there are still deficiencies in the stability, persistence of negative ion release and the high-concentration release of small-sized negative ions.

[0004] The present invention provides a highly efficient and persistent negative oxygen ion spray by optimizing the composite system of nano-mineral materials and photocatalyst and combining plant extracts, which can continuously release small-sized negative ions in an enclosed environment, and the purification effect can last for 7 days.

[0009] A preparation method of the above-mentioned negative oxygen ion spray, which is made into a spray through the nano-carbonized plant modification and activation technology by combining the above raw materials, specifically as follows: Step 1, raw material pretreatment: The nano-tourmaline powder and rare spar are ultra-finely pulverized to a particle size ≤ 100 nm, and surface modification treatment is carried out to improve the dispersibility.

[0010] Step 2, mixing the nano-TiO₂ with the modified tourmaline powder and rare spar in proportion, adding a nano-carbonized plant modification activator, and stirring and reacting at 60-80 °C for 2 hours to form a supported composite catalyst.

[0011] Step 3, gradually adding the composite catalyst and the plant extract into deionized water, and treating with a high-pressure homogenizer (pressure ≥ 50 MPa) for 30 minutes to form a stable suspension.

[0012] Step 4, after filtration, it is filled into a light-shielding spray container to prevent the photocatalyst from being activated in advance.

[0013] Further, in Step 1, the nano-tourmaline powder and rare spar are respectively placed in an ultra-fine pulverization device, and the particle size of the raw materials is processed to less than 100 nanometers by a combination of mechanical grinding and air flow pulverization. Subsequently, a silane coupling agent is used for surface modification treatment of the ultra-fine powder to improve its dispersion stability in the subsequent process.

[0015] Further, in the third step, the composite catalyst obtained in the second step and the plant extract are alternately added to deionized water in three times. After each addition, the mixture is cyclically treated for 10 minutes under a pressure of 50 - 60 MPa by a high-pressure homogenizer, and the cumulative treatment time is 30 minutes to form a suspension system with uniform particle size distribution and stable Zeta potential.

According to the weight ratio, 10 parts of photocatalyst nano-TiO₂, 15 parts of tourmaline powder, 5 parts of rare spar, 3 parts of plant extract, and 27 parts of deionized water The above-mentioned raw materials are made into a spray through the nano-carbonized plant modification and activation technology, specifically as follows: Step 1: Pretreatment of raw materials. The nano-tourmaline powder and rare earth stone are ultra-finely ground to a particle size ≤ 100 nm, and surface modification treatment is carried out to improve the dispersibility.

[0020] Step 2: Mix nano-TiO₂ with the modified tourmaline powder and rare earth stone in proportion, add the nano-carbonized plant modification activator, and stir and react at 60 - 80 °C for 2 hours to form a supported composite catalyst.

[0021] Step 3: Gradually add the composite catalyst and plant extract into deionized water, and treat with a high-pressure homogenizer (pressure ≥ 50 MPa) for 30 minutes to form a stable suspension.

[0022] Step 4: After filtration, fill it into a light-proof spray container to avoid premature activation of the photocatalyst.

[0023] This example can release 1600 negative ions / cm³ within 24 hours, and the degradation rate of formaldehyde reaches 82%.

[0024] Example 2: Using a medium-concentration formulation design, according to the weight ratio, the proportion of each component is 15 parts of photocatalyst nano-TiO₂, 20 parts of nano-tourmaline powder, 8 parts of rare earth stone, 6 parts of plant extract, and 50 parts of deionized water.

[0025] The above-mentioned raw materials are made into a spray through the nano-carbonized plant modification and activation technology, specifically as follows: Step 1: Pretreatment of raw materials. The nano-tourmaline powder and rare earth stone are ultra-finely ground to a particle size ≤ 100 nm, and surface modification treatment is carried out to improve the dispersibility.

[0026] Step 2: Mix nano-TiO₂ with the modified tourmaline powder and rare earth stone in proportion, add the nano-carbonized plant modification activator, and stir and react at 60 - 80 °C for 2 hours to form a supported composite catalyst.

[0027] Step 3: Gradually add the composite catalyst and plant extract into deionized water, and treat with a high-pressure homogenizer (pressure ≥ 50 MPa) for 30 minutes to form a stable suspension.

[0028] Step 4: After filtration, fill it into a light-proof spray container to avoid premature activation of the photocatalyst.

[0029] This example shows more excellent performance. The negative ion release amount within 24 hours is increased to 2000 negative ions / cm³, and the formaldehyde degradation rate is increased to 88%, and the purification effect is significantly enhanced.

[0030] Example 3 uses a high-concentration formula, and the proportion of each component is 20 parts of photocatalyst nano-TiO₂, 25 parts of nano-tourmaline powder, 10 parts of rare spar, 8 parts of plant extract, and 62 parts of deionized water.

[0032] Step 2, mix nano-TiO₂ with the modified tourmaline powder and rare spar in proportion, add nano-carbonized plant modification activator, and stir and react at 60 - 80 °C for 2 hours to form a supported composite catalyst.

[0033] Step 3, gradually add the composite catalyst and plant extract into deionized water, and treat it with a high-pressure homogenizer (pressure ≥ 50 MPa) for 30 minutes to form a stable suspension.

[0034] In this example, the negative ion release amount reaches 2400 ions / cm³ in 24 hours, and the formaldehyde degradation rate is as high as 92%, showing the most excellent air purification performance.

[0035] As a control, the ordinary negative ion spray only contains 25 parts of tourmaline powder and 75 parts of deionized water. Its 24-hour negative ion release amount is only 800 ions / cm³, and the negative ion particle size is relatively large (> 2 nm). The purification effect can only be maintained for 1 - 2 days, and the formaldehyde degradation rate does not exceed 50%. This comparison result fully proves the performance advantages achieved by the present invention.
