Description
Technical field
The present invention relates to paint field, particularly relate to a kind of antibacterial interior wall latex paint.
Background technology
Along with improving constantly of living standard, people are more and more stronger to the pursuit of healthy clean ecology living environment. The investigation that living environment microorganism is polluted shows: rural area total number of bacteria is 138.94cfu/cm2, cities and towns are 72.10cfu/cm2. As can be seen here, the pollution that in living environment, microorganism causes is very important. Therefore the daily dependent antimicrobial materials such as present antibiotic paint, antibiotic plastic, antibacterial film, antibacterial cosmetic arise at the historic moment.
Keeping environmental nonpollution is stop antibacterial, virus on human to infect practical ways, and using anti-biotic material is realize the most simple and effective way of environmental nonpollution. Antibiotic paint can directly be coated with and be contained on various material, receives much concern because it is easy to use, develops the coating with antibacterial functions or paint is one of coatings industry developing direction. Antibiotic paint be by add have antibacterial functions and can in film the antibacterial of stable existence and make. There is the coating range of application expanding day of antibacterial functions, expand non-metal substrate field to from metal substrate field. Traditional antibacterial mildew inhibitor, such as formaldehyde, phenol, penta sodium pentachlorophenate, heavy metallic salt etc., owing to environment and human body are also harmful to by it, have been inhibited in coating and have used.
Emulsion paint is being commonly called as of latex paint, is born in nineteen seventies the next period, be representative with acrylate copolymer emulsion a big class synthetic resin emulsion coating. Emulsion paint is water-dispersible paint, and it is with synthetic resin emulsion for base material, and filler adds the coating that various auxiliary agent is refined after grinding distribution. Emulsion paint has possessed the many merits different from conventional wall coating materials, as be prone to brushing, dry rapidly, paint film is water-fast, scrub resistance is good. In China, people are base material synthetic resin emulsion traditionally, with water for disperse medium, add pigment, filler (also known as extender pigment) and auxiliary agent, through the coating that certain technical process is made, are called emulsion paint, are also latex paint. Interiro wall latex paint is that one of most common ornament materials is applied in current house fitting, and it has many advantages such as easy construction, strong covering power, rich color, scrubbing resistance, and collocation of colour is proper, quality is guaranteed, it is possible to provide a warm environment to family.
At present, common microbiological, staphylococcus aureus, escherichia coli, Candida albicans and yeast, mycete etc. are not killed and inhibitory action by traditional emulsion paint, people can not be relieved safely when using use, and select general antibiotic emulsion paint effectively not better people's living environment. Therefore, exploitation one safely and effectively antibiotic emulsion paint is needed badly, to meet the demand of people.

The performance test experiment of antibiotic emulsion paint of the present invention.
1, anti-microbial property test: antibacterial interior wall latex paint of the present invention for 0.5g is painted on PVC plastic substrate (10mm �� 10mm), dries rear ultraviolet-sterilization 1 hour. After configuration meat extract peptone agar culture medium sterilizing, pour the prepared flat board of sterilized culture dish into standby. With physiological saline solution, strain Escherichia coli is configured to 104The bacterium solution of about cfu/ml, and measure viable count N(cfu/ml with colony counting method); Draw bacterium solution with Sterile pipette to drip and paint in antibacterial latex of the present invention, contact certain time (2 hours, 5 hours) with antibiotic emulsion paint of the present invention after, then draw bacterium solution and drip on flat board, uniform by aseptic triangle rod coating. Flatbed horizontal is moved to after 35 DEG C of constant incubators are cultivated 20 hours, take out the clump count calculated on flat board, obtain the viable count N contact certain time (2 hours, 5 hours) with antibiotic emulsion paint of the present invention after1(cfu/ml), result is in Table 1, and table 1 is the antibacterial situation of antibacterial interior wall latex paint of the present invention. The computing formula of bacteriostasis rate is as follows: bacteriostasis rate n%=(N-N1)/N��100%��
Table 1: the antibacterial situation of antibacterial interior wall latex paint of the present invention.
| Test microbes | Viable count (cfu/ml) before contact | Viable count (cfu/ml) after contact 2h | Viable count (cfu/ml) after contact 5h |
| Escherichia coli | 1.3��104 | 9.8��102 | 2.5��102 |
| Bacteriostasis rate | - | 92.46% | 98.08% |
As shown in Table 1, after brushing antibacterial interior wall latex paint of the present invention, after contacting with bacterium solution 2 hours, bacteriostasis rate is 92.46%, and after contacting 5 hours, bacteriostasis rate is 98.08%. As can be seen here, antibacterial interior wall latex paint of the present invention has significant antibacterial effect.
The Antibacterial Mechanism of antibacterial interior wall latex paint of the present invention: (1) zinc oxide is a kind of good inorganic antiseptic inherently, the zinc ion slowly released in interiro wall latex paint has good oxidation-reduction quality, can react with organic carboxyl, hydroxyl etc., destroy its structure, the enzyme destroying electron transport system after entering microbial cell reacts with-SH base, reaches the purpose of sterilization. After killing antibacterial, zinc ion can separate out from cell middle reaches, repeats said process. (2) nano zine oxide also has photocatalytic, under ultraviolet irradiation condition, can discharge hole and electronics. Hole makes H2O aoxidizes, and electronics makes the O in air2Reduction, forms the OH free radical with Strong oxdiative ability, and the microorganism contacted with emulsion paint film has suppression and killing action. (3) nano zine oxide is by preventing the absorption of light and scattering process or delaying the light degradation of emulsion in coating, utilizes the oxidizing species that photocatalysis produces to make microbial cell tissue lose activity simultaneously. Owing to nanoparticle itself is not engaged in reaction, so not loss, and then there is long-acting bacteriostasis.
2, determination experiment drying time result: under room temperature (23 �� 2) DEG C, the mensuration environment of relative humidity (50 �� 5) %, the surface drying time of this antibacterial interior wall latex paint is 20 minutes, and dry-hard time is 50 minutes.
3, consumption paint measures test result: the theory consumption paint amount of described antibacterial interior wall latex paint is 8-12 square metre/kilogram/single pass (dry film 30 ��m meter); Because the degree of roughness on practice of construction surface, degree of compaction, aridity and coating dilution ratio are different, consumption paint amount can be different.
4, condition of storage test result: the condition of storage of described antibacterial interior wall latex paint is: leaving the dry and comfortable place, cool place of 5-35 DEG C in, packing specification is 20 kilograms/barrel.
