Problems solved by technology

[0002] At present, there are roughly three types of kitchen and bathroom cleaning technology and cleaning products: the first is strong alkali type, which has a good ability to remove heavy oil stains, but due to strong alkalinity, it is easy to cause hand Discomfort or damage to the surface of the appliance, which is dangerous
The second type is solvent-based. This type of cleaner mainly achieves the purpose of removing oil stains through the dissolution and shedding of oil stains by organic solvents and the emulsification and solubilization of surfactants. However, this product contains more organic solvents. The smell is relatively strong, and at the same time, organic solvents may cause certain damage to the paint surface of kitchen and bathroom appliances, causing losses to users.
JP2005-082708A discloses a laundry detergent, which contains a photocatalyst such as titanium dioxide. Under light, the oxidizing substances produced by the photocatalyst, such as superoxide anions and hydroxyl radicals, can play a role in sterilization and disinfection, but the oxidation of the photocatalyst The reaction proceeds slowly, and the components of the detergent itself are decomposed by the photocatalyst, and are easy to precipitate, that is, the dispersion stability is not high
[0005] CN101565656A discloses a laundry material, including nano-anion powder, 4A zeolite, photocatalyst, anionic surface active material, polymer binding material, polymer curing material, etc., but this is a solid detergent, and does not disclose any aspect of effect result

preparation example 1

[0037] (1) Mix anatase-type titanium dioxide powder with a particle size of 10 nm and urea and stir evenly, then keep at a temperature of 400 ° C for 40 minutes to obtain nitrogen-doped anatase-type titanium dioxide powder, wherein the mass ratio of titanium dioxide to urea is 30:1.

[0038](2) Mix n-octyltrimethoxysilane and the above-mentioned nitrogen-doped anatase titanium dioxide powder with a mass ratio of 1:50 in ethanol with a mass percent concentration of 95% for 2 hours, then centrifuge and wash with acetone 3 times, and then vacuum-dry at 40°C to obtain titanium dioxide powder with a surface-modified silicon oxide layer, which is named SiTiN-1. Tested by transmission electron microscope, the average particle size is 12nm.

preparation example 2

[0040] (1) Mix anatase titanium dioxide powder with a particle size of 15nm and urea and stir evenly, then insulate at a temperature of 480° C. for 45 minutes to obtain nitrogen-doped anatase titanium dioxide powder, wherein the mass ratio of titanium dioxide to urea is 50:1.

[0041] (2) n-octyltrimethoxysilane and the above-mentioned nitrogen-doped anatase titanium dioxide powder were mixed and stirred for 5 hours in ethanol with a mass percentage concentration of 95% at a mass ratio of 1:75, then centrifuged, and washed with acetone for 4 hours. times, and then vacuum-dried at 50°C to obtain a titanium dioxide surface-modified with a silicon-oxygen layer, named SiTiN-2. Tested by transmission electron microscope, the average particle size is 17nm.

preparation example 3

[0043] (1) Mix anatase titanium dioxide powder with a particle size of 20nm and urea and stir evenly, then insulate at a temperature of 550° C. for 50 minutes to obtain nitrogen-doped anatase titanium dioxide powder, wherein the mass ratio of titanium dioxide to urea is 65 : 1.

[0044] (2) n-octyltrimethoxysilane and the above-mentioned nitrogen-doped anatase titanium dioxide powder were mixed and stirred for 10 h in ethanol with a mass percentage concentration of 95% at a mass ratio of 1:100, then centrifuged, and washed with acetone for 5 h. times, and then vacuum-dried at 55°C to obtain a titanium dioxide surface-modified with a silicon-oxygen layer, which was named SiTiN-3. Tested by transmission electron microscope, the average particle size is 23nm.

Abstract

The invention relates to a kitchen and bath detergent and a preparation method thereof. The kitchen and bath detergent is prepared from, 0.5-5% of titanium dioxide with surface modified with a silica layer, 0.001-0.1% of copper acetate, 0.1-1% of activated carbon, 5-15% of an activating agent, 5-30% of a non-ionic surface active agent and the balance deionized water. The kitchen and bath detergent produced through the formula has the equivalent cleaning effect as other detergents, still keeps the quite high sterilization rate even after six months, has the excellent sterilization and disinfection effect for bacteria remaining on kitchen tableware or other hard surfaces, and is excellent in stability.

Description

technical field [0001] The invention relates to a kitchen and bathroom cleaning agent, in particular to a kitchen and bathroom cleaning agent containing a photocatalyst and a preparation method thereof, belonging to the field of kitchen and bathroom cleaning. Background technique [0002] At present, kitchen and bathroom cleaning technology and cleaning products are roughly divided into three types: the first is the strong alkaline type, which has a good ability to remove heavy oil stains, but due to its strong alkalinity, it is easy to cause the user's hand It is dangerous to cause discomfort or damage to the surface of the appliance. The second type is solvent-based. This cleaning agent mainly achieves the purpose of removing oil stains through the dissolution and detachment of organic solvents to oil stains and the emulsification and solubilization of surfactants. However, this product contains more organic solvents. The smell is relatively large, and at the same time, o...
