Abstract
The present invention relates to a photocatalyst bactericidal purifying agent and a preparation method thereof, which is applied to products, such as indoor artwork ornaments, furniture, curtains, toys, etc. At present, indoor environments are polluted by different degrees under various conditions. Micro organism bacteria and harmful gases floated in air are harmful for the health of people's life; Purification products for indoor air on the markets can be divided into physical absorption type products, chemical type products, ionization type products, and traditional spraying agent type products on theories. When the methods are adopted, the functions of cleaning the air can be realized by a certain degree, and the products can not fundamentally realize the aim of purifying the indoor environments. The present invention is manufactured by adopting various nanometer materials; the present invention is sprayed on the surface of the products, and kills and represses the growth of the harmful bacteria under the action of the photocatalysts; thereby, the present invention has favorable efficiency for decomposing and purifying the viruses and the bacteria in the air.
Description
Technical field
The present invention relates to a kind of photo-catalytic sterilization clarificant and preparation method, especially be applied to products such as chamber processes ornament, furniture, curtain, toy.
Background technology
All there is pollution in various degree under various conditions in indoor environment at present.Microbial bacterial that swims in the air and pernicious gas are endangering people's life health.The indoor air purification product that we can see on market can be divided on principle: physisorption type, chemical type, ionization type and traditional spray type.Adopt these means can on certain degree, play the effect of clean air, but these products can't fundamentally purify indoor environment, especially concerning " room air killers " such as bacterial micro-organisms with procreation ability, these products exist all that effect is single, timeliness is short, produce peculiar smell, produce noise, repeat consumption and problem such as pollution is for the second time arranged.These products can not fundamentally reach the indoor purifying purpose of permanence.
Can only be at eliminating formaldehyde as formaldehyde catching agent, and can not remove other pernicious gas.Its effect is single, and generate another kind of chemical substance behind the chemical reaction of formaldehyde generation in use, can not decomposing formaldehyde gas in molecule, make it to become innocuous substance, powerless to the pernicious gas that the later stage continues to distribute, be limited, the simple strained handling means of a kind of scope of application.
Deodorization and sterilization aromatic is a kind of product that leans on the peat-reek that self volatilizees to cover other bad air, and it can make a kind of good mixing gas, but can not reach the effect of real lasting sterilization.Smell disappears, and function also together disappears, as re-uses and need constantly repeat consumption, and long-term use meeting produces bad negatively influencing to human body.
Activated carbon adsorbent is to utilize the physical features of porous active carbon to come big molecular gas and suspended particulate in the absorbed air, is the purpose that reaches filtration, purification by forced-air circulation mostly as smog, dust.But need the periodic replacement filter core, actual service efficiency is not high, and noise is arranged, and can not reach the effect of resolving harmful gas and sterilization.
Tradition disinfecting sprays and antibacterial agent (as disinfectant, cleaning agent, freshener) they all are organic products, its killing bacteria efficient height, and instant effect, but can not decomposing organic matter, microorganism after killing and bacterium corpse rot, and have caused secondary pollution again.Its drug resistance, warm tolerance are relatively poor, belong to fugitive disposable antibacterial product.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of employing nano material preparation technology is provided, be issued to the photo-catalytic sterilization clarificant and the preparation method of sterilizing and purifying air in the effect of photocatalyst.
Technical scheme of the present invention is: a kind of photo-catalytic sterilization clarificant, add by photo-catalytic sterilization clarificant masterbatch that blending and stirring forms in the composite fluid to, it is characterized in that the proportioning composition by weight of photo-catalytic sterilization clarificant masterbatch is: the nanometer anatase titanium dioxide powder (30-50nm), the infrared rays powder of 4-7 part, 3-6 part silver nitrate, the 2-4 part nm-class rutile-type TiO 2 powder that adopt 6-8 part; The cooperation composition by weight of composite fluid is: 50 parts water, 1 part of alcohol, 20 parts resin, 3 parts of suspending agents and 1 part of essence.
Described infrared rays powder is made up of nano titanium dioxide powder, titanium dioxide, nanometer zirconium powder.Above-mentioned resin is meant adjacent benzene type unsaturated polyester resin DS-909-2 or high activity unsaturated polyester resin DS-258 and air-dried unsaturated polyester resin PE.Suspending agent is selected acrylate copolymer and hydroxypropyl cellulose for use.Essence is general water quality class, emulsification class or powdery type.
A kind of preparation method of photo-catalytic sterilization clarificant, its in the following order step carry out:
1, make composite fluid: in weight portion is 50 parts water, add 1 part of alcohol, after stirring, add 20 parts resin successively, 3 parts of suspending agents and 1 part of essence are through mixing together;
2, make photo-catalytic sterilization clarificant masterbatch: be nanometer anatase titanium dioxide powder (30-50nm), the infrared rays powder of 4-7 part, 3-6 part silver nitrate, 2-4 part nm-class rutile-type TiO 2 powder of 6-8 part with weight portion, add successively, even through blending and stirring;
3, the photo-catalytic sterilization clarificant masterbatch that will make with step 2 adds in the composite fluid made from step 1, is processed into the photo-catalytic sterilization clarificant through blending and stirring.
After adding the alcohol in 50 parts of water of weight portion, the alcoholic strength of liquid is controlled at 8-10 °, and fluid temperature remains on 21 ℃.
This kind photo-catalytic sterilization clarificant paint application has sterilizing, purifies self-cleaning effect in products such as chamber processes ornament, furniture, curtain, toys.
The present invention adopts multiple nano material to make, and is sprayed at product surface, and under the effect of photocatalyst, nano particle is very strong to the change thing effect of bacterial cell, very easily advances people's cell interior structure.Therefore, it can kill and suppress the growth of noxious bacteria, and the airborne virus and bacteria of decomposing, purifying is had extremely strong effect.Being sprayed at decoration technology with the agent of photocatalyst bactericidal purifying takes, with this product censorship, microbiological analysis inspection center is by FZ/T01 021-92 (antibacterial fabric has test method), GB15979-2002 (appendix C-product antibacterial and bactericidal property and stability test method) detects testing result: this product is 99.99% to the antibiotic rate of colon bacillus; Antibiotic rate to Staphylococcus aureus is 99.79%; The clearance of PARA FORMALDEHYDE PRILLS(91,95) is 72%; Clearance to dimethyl sulphide is 59.89%.
