Abstract
The invention relates to a mildew-proof pH test paper and a preparation method of the mildew-proof pH test paper. The mildew-proof pH test paper is prepared by dipping filter paper into a pH test paper coating liquid containing a mildew-proof agent O, i.e. 5,6-dichloro benzoxazolinone, for 5-10 seconds; taking out the paper; and drying in hot air or in an infrared drying cabinet at a drying temperature of 70-100 DEG C. The content of the mildew-proof agent O is 0.03-1.0wt% of the total weight of the pH test paper coating liquid. The mildew-proof pH test paper provided by the invention has the characteristics of being good in mildew-proof effect, long in mildew-proof time, small in additive amount of the mildew-proof agent, small in resource investment and the like. The pH test paper product prepared by the method provided by the invention is the first one which is marked with a validity period of three years.
Description
One, technical field
The present invention relates to a kind of test paper for detection of solution acid alkalinity and preparation method thereof, relate in particular to pH test paper of a kind of mildew-resistant and preparation method thereof.
Two, background technology
Detect the method for solution acid alkalinity, conventional have pH instrument and a pH test paper.PH test paper has again the feature of simple and easy, convenient, fast, cheapness and non-secondary pollution because of it, more and more be widely used in chemical analysis, industry, agricultural, aquaculture and medicine and other fields, and to water analysis, in the analysis and daily life of the saliva of human body, sweat, blood, urine.Along with the large batch of production of pH test paper, civilian pH test paper life cycle is long, and the problem of going mouldy of test paper is more outstanding, has restricted production and the use of pH test paper.Domestic and international existing technology all adopts carrier directly to make the pH test paper of different size at the indicator dipping of different proportionings, and carrier is the filter paper of being made up of the raw material such as cotton fiber, starch.In production, packaging, storage and the use procedure of pH test paper, because the effect of microorganism is gone mouldy, in pH test strips, just there will be mildew and large stretch of mouldization, particularly pH test paper outward appearance is blue or green for more very, cause the mistake of test result, make pH test paper afunction, and lose use value.The clear 61-30755 of JP, JP2000-171456 and Britain GB96083, open by apply the technology of the water-fast synthetic resin of one deck and air insulated on pH test paper surface respectively, reach the stable effect of test paper.This technical difficulty is high, has high input, and causes the colour developing of test paper slow.Current prior art does not have effectively to solve the method for pH test paper mildew-resistant.
Three, summary of the invention
The object of the invention is, in order to overcome the shortcoming in background technology, provides pH test paper of a kind of mildew-resistant and preparation method thereof.
The present invention is achieved in that a kind of pH test paper of mildew-resistant, is characterized in: the pH test paper of this mildew-resistant is taken out and makes containing after mildewproof agent O flooded for 5～10 seconds in the pH test paper coating fluid of 5,6-dichloro benzo oxazoline ketone by filter paper; The content of mildewproof agent O accounts for 0.03～1.0wt% of pH test paper coating fluid general assembly (TW).
The preparation method of the pH test paper of this mildew-resistant is: the mildewproof agent O being dissolved in 95wt% ethanol is joined in pH test paper coating fluid, obtain the pH test paper coating fluid that contains mildewproof agent O, the content of mildewproof agent O accounts for 0.03～1.0wt% of pH test paper coating fluid general assembly (TW), and in the pH test paper coating fluid that contains mildewproof agent O, the weight ratio of second alcohol and water is 0.5～1.0:1.0; Regulate the pH value of the coating fluid that contains mildewproof agent O to equal 4～8 with NaOH solution or HCl solution; After being flooded to 5～10 seconds in the pH test paper coating fluid that contains mildewproof agent O, takes out by filter paper, dry in hot-air or infrared drying oven, 70～100 DEG C of baking temperatures, obtain the pH test paper of mildew-resistant, and the pH test paper of dried mildew-resistant is through cutting packing cost, circle or bar.
Mildewproof agent O in the present invention i.e. content >=the 98wt% of 5,6-dichloro benzo oxazoline ketone.
The present invention's tool compared with domestic and international prior art has the following advantages::
1, in currently available technology, also do not carry out the research of mildew-resistant and the report of achievement about pH test paper with mildewproof agent.
2, in currently available technology, cannot indicate the use term of validity of pH test paper, the pH test paper of mildew-resistant of the present invention can be indicated the use term of validity of pH test paper.
3, mildewproof agent O of the present invention is by applicant's first development and production at home, and offers the scientific research institutions of cable, electrical equipment, light industry, coating, in the mildew-resistant application in the fields such as cable, electrical equipment, leatheret, resin, coating.The present invention is the mildew-resistant for pH test paper with mildewproof agent O, is to make bacteriostasis property, the working concentration to the mildew-resistant of pH test paper to other type mildewproof agent, and make on the performance test of impact on test paper color development and anti-mold effect and Performance Ratio basis.The pH test paper of mildew-resistant of the present invention has pH test paper quality influence little, and anti-mold effect is good, and the mildew-resistant time is long and mildewproof agent addition is few, and resource drops into the features such as little.The pH test paper product of the production of mildew-resistant of the present invention is first test paper of having indicated 3 years terms of validity.
Four, embodiment
In order to implement better the present invention especially exemplified by following embodiment, but embodiment is not the restriction to invention.
Embodiment 1
