Description
Technical field
The present invention relates to technical field of coatings, more particularly to a kind of power switch cabinet with the hydrophobic antibacterial powdery paints of silicon substrate and
Its preparation method.
Background technology
With social development, the demand of anti-biotic material will constitute huge market, and the production of antiseptic and its product will be into
It is important new industry field.Substantially, temperature tolerance is poor, service life is short for the short-term bactericidal effect of organic antiseptic；Inorganic
Antiseptic working life is long, and high temperature resistant has side effect.And complex antimicrobials greatly improve antibacterial rationally using both advantages
Agent performance and the scope of application, overcome the limitation of single antibacterial antiplaque agent spectrum.Composite antibacterial material will be that anti-biotic material is sent out from now on
Open up direction and the main points of application；
M-hydroxybenzoic acid has active anticancer by suppressing xanthine oxidase, and 8-hydroxyquinoline also has certain antibacterial
Activity.Rare earth-septichen -8-hydroxyquinoline ternary complex has been synthesized, rare earth-P-hydroxybenzoic acid -8- hydroxyls
Quinoline ternary complex has also been synthesized.But, the synthesis of rare earth-m-hydroxybenzoic acid -8-hydroxyquinoline ternary complex,
Structure and property research are not reported so far, the synthesis and the antibacterial that have m-hydroxybenzoic acid phenanthroline complex of rarely seen report
Property Quality Research, but this complex is only higher in concentration（>500ppm）When just show bacteriostasis property.Rare earth ion due to
Its special electron structure, can stop the metabolic process of mushroom, with extensive antibacterial action.Left beautiful duckweed et al. proves
In excessive earth solution, Niger's aspergillus fungi can be combined rapidly with rare earth ion, make the breathing of fungal cell and grape
Utilizing for sugar reduces, until stopping.Rare earth ion has anti-inflammatory, sterilization, anticancer, anticoagulation, analgesic activity again simultaneously.Due to dilute
Native ion can strengthen its fungistatic effect after forming complex, therefore in recent years, this field progressively causes attention and the pass of people
Note.Lin Feng, what water sample, Wang Liufang have been respectively synthesized different rare earth compoundings and have made bacteriostatic experiment, it was demonstrated that complex it is antibacterial
Ability is better than independent part and corresponding rare earth ion.In addition, China is the abundant country of rare earth resources, rare earth resources are developed
It is the long-term fundamental state policy of one, China.The research application of Rare Earth Functional Materials has important economic implications and social effect.Cause
This, study on the synthesis has the rare earth compounding of good bacteriostasis property, develops new application field, explores rational production procedure etc.
With important theory and realistic meaning.
Antibacterial powder paint refers to that the film that powdery paints is made has antibiotic property, can kill or suppress to attach on film
Bacterium.Powdery paints is widely used in goods showing cabinet, refrigerator, water dispenser, bed product, furniture of steel, kitchen utensils, food work
Industry equipment, hospital facility etc..These be all people often in contact with utensil.Therefore, the development and Application of antibacterial powder paint has
Important social effect.Since the nineties, the western developed country such as Japan has developed antimicrobial form powdery paints in succession, and
China is still in the starting stage in this respect.With the continuous improvement of people's living standard and environmental protection consciousness not
Disconnected enhancing, antimicrobial form powdery paints opens a new approaches for health for powdery paints application field.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of power switch cabinet is hydrophobic antibacterial with silicon substrate
