Abstract
The present invention relates to an antimicrobial agent for plastic, which uses AgNO3, Zn (NO3)2, ZnSO4, ZnO, dispersants and zeolite as raw materials and is formed by controlling the proportion of components and adopting the definite steps. The antimicrobial agent has the characteristics of broad antimicrobial spectrum, good color stability, extensive application range, etc.
Description
The present invention relates to use compounds such as metallic compound such as silver, copper, zinc and activation silicon, boron, by the specific support appendix and make up and make antibacterial agent that is used for antibiotic plastic and preparation method thereof.
People have found that for a long time silver, copper, zinc metal and compound thereof have sterilizing function.Huang Lizhong has reported the application of silver compound aspect clinical medicine.As use AgNO
3Solution or collargol are handled wound, are used (noble metal, 1995,16 (2): 72) such as sulfadiazine silver is antimycotic, inhibition virus.Tokuyama disclosed by Cu in 95 years
2+, Zn
2+, Cr
3+The antibacterial components of making Deng the compound and the respective ligand of composition is used for the coating manufacturing, resists bacterium and algae (JP95-133444).It is not long that but the antibacterial functions that utilizes this metal compound prepares the history of antibiotic plastic.Up to the present, three phases has roughly been experienced in the antibacterial agent development that is used for antibiotic plastic:
1. soluble compound directly adds to and makes antibiotic plastic in the resin.But the antibiotic plastic of this method preparation not only performance descends, and the antibiotic term of validity is very short;
2. be that carrier appendix metal ion prepares antibacterial agent with the active carbon.But the antibiotic plastic with this antibacterial agent preparation is a black, and the scope of application has been subjected to very big restriction:
3. use the stronger material of chemical bond power to make carrier appendix antibacterial material and prepare antibacterial agent.
People such as the middle island of Kanebo Ltd and a man of virtue and ability, peace rattan acute hearing disclose the patent of " stable zeolite and preparation method thereof ", reported with the zeolite and be preparing carriers antibacterial agent (JP91-131513), the Yamamoto moral smelting of upright nitre Co., Ltd. discloses the patent of " glass-based water treatment agent " altogether, reported to be that the hillside plot farming of antibacterial agent (JP87-210098) Sumitomo Seika Co., Ltd of carrier discloses the patent of " preservative constituent for building " with the glass microballoon, reported to be the antibacterial agent (JP91-191145) of carrier with silica gel.And this class antibacterial agent has been applied to every field such as construction material, household electrical appliance gradually.
But the main active ingredient of inorganic antiseptic is generally compounds such as silver, zinc, copper at present, and general antibacterial agent all contains Ag
+Because Ag
+To photo-labile, easily deposit or use in cause variable color.This problem has seriously restricted the range of application of antibacterial agent, especially to fields such as the exigent household electrical appliances of outward appearance, calculators.
The present invention has overcome present antibacterial agent ubiquitous discoloration problem in preservation and use, and has proposed the new prescription of synthesizing new antibacterial agent and new preparation technology.The antibacterial agent non-toxic efficient broad-spectrum sterilization that makes, little to the mechanical property influence of plastics, and have excellent colour stability.
Antimicrobial composition of the present invention comprises following component and content (weight portion):
The preferable content of constituent content
AgNO
3 0-2
Zn(NO
3)
2 0.1-60 20-50
ZnSO
4 0-50 30-40
ZnO 5-80 20-50
Dispersant 0.5
Zeolite 100
Antibacterial inorganic preparation of compositions method of the present invention is carried out in the following order:
1. by weight with the AgNO of 0-2 part
3, 0.1-60 part Zn (NO
3)
2ZnSO with 0-50 part
4Be mixed with the AgNO of 0-5% respectively with deionized water
3Solution, 10%～saturated Zn (NO
3)
2And ZnSO
4Solution for later use.
2. at above-mentioned AgNO
3Add 100 parts of zeolites in the solution, form uniform slurries, be heated to 80 ℃～boiling, and under this temperature, keep stirring 20～100min, stop to stir and being cooled to room temperature with mechanical agitation or electromagnetic agitation, treat the slurries precipitated and separated after, topple over and fall supernatant.In the beds of precipitation, add above-mentioned Zn (NO then
3)
2And ZnSO
4Solution becomes electromagnetism to stir with mechanical agitation and is heated to 60～90 ℃ after material stirs into homogeneous slurry, reaction 60～300min.
3. add dispersant in above-mentioned slurries, stop heating after stirring, etc. after the system cooling slurries are dried, powder particle diameter is less than the pressed powder of 30 μ.
4. at the last ZnO powder that adds 5-80 part in the powder that obtains that goes on foot, mix, promptly obtain bactericidal composition of the present invention.
Preparation AgNO
3During solution, concentration is advisable with 0-2%, and excessive concentration can cause and adds behind the zeolite feeding-uply, influence subsequent process and operates.
Preparation Zn (NO
3)
2During solution, concentration is advisable with 30-40%.Concentration is crossed and low can be caused that metal ion appendix amount is on the low side, and workload is big when causing drying, energy waste.
Heating AgNO
3, temperature should be controlled at 94-99 ℃ and is advisable during the zeolite mixed serum, temperature is crossed and lowly can be caused that gas residual quantity increases in the zeolite, ion appendix ability drop, the high slightly then system boiling of temperature can cause that again moisture evaporation is too fast, operating difficulties.
Add Zn (NO
3)
2, ZnSO
4Behind the solution, slurry temperature should be controlled at 65～75 ℃ and be advisable.Temperature is too high, and moisture evaporation is too fast, influences the appendix reaction of ion.Temperature is low excessively, causes zeolite appendix amount to descend.
Above-mentioned dispersant is CA-977, HYDROPALAT or SN-DISPERSANT.
Escherichia coli, bacillus subtilis, staphylococcus aureus, Sarcina lutea, aspergillus flavus, Penicillium citrinum, Mucor racemosus, prunosus red coccus etc. all have good inhibitory effect during antibacterial inorganic composition that the present invention makes, and it is 0.05% to enteropathogenic E minimal bactericidal concentration (weight portion).
The present invention makes bactericidal composition and has good colour stability, and through 200hr standard uviol lamp accelerated ageing experiment, its result shows difference DELTA E≤2 of the aberration of its aberration and corresponding base material.
The present invention makes the inorganic antibacterial composition and can directly add plastics such as PVC, PE, PP, PS, ABS, PET, PBT, PA, TPU, PC, PMMA, SAN to and be prepared into antibiotic plastic, also can be prepared into earlier in the plastic basis material that antibacterial matrices adds above-mentioned kind again to and be prepared into antibiotic plastic.Having added its mechanical property of antibiotic plastic of the present composition and un-added corresponding base material plastics mechanical property differs and is no more than 10%.
