Description
Technical field
The present invention relates to medical apparatus technical field, more particularly to a kind of endoscope surface antibiotic paint.
Background technology
Endoscope is to have concentrated traditional optical, ergonomics, precision optical machinery, hyundai electronicses, mathematics, software etc. in one
Detecting instrument.One has imageing sensor, optical lens, light source lighting, mechanical device etc., and it can enter stomach with direct oral cavity
It is interior or internal through the entrance of other natural holes.Using endoscope it can be seen that the lesion that can not show of X-ray, therefore it is to doctor
It is highly useful, for example, the ulcer or tumour in stomach can be observed by endoscope doctor, optimal treatment side is made accordingly
Case.Endoscope needs to enter into inside of human body, therefore, its antibacterial surface performance is substantially that its is required.
The content of the invention
It is an object of the invention to provide a kind of endoscope surface antibiotic paint.
The present invention is achieved through the following technical solutions：
A kind of endoscope surface antibiotic paint, it is characterised in that be made up of following component by weight：Shitosan-rabdosia lophanthide
Complex 0.4-0.8, acrylic emulsion 100-110, polyvinyl alcohol 5-8, wood-fibred 1.2-1.6, titanium dioxide 2-4, rosin 1-3,
Nano silicon micronization 2-5, water 30-50；
The shitosan-rabdosia lophanthide complex preparation method is：
1. use mass fraction to be dissolved for 1.2% hydrochloric acid solution shitosan, obtain the shitosan that mass fraction is 5% molten
Liquid；
2. rabdosia lophanthide is rubbed, the Os Sus domestica powder of addition rabdosia lophanthide quality 2% adds mass fraction for 2% ammoniacal liquor is stirred, and adds
Alkali protease, at 50 DEG C, pH is under conditions of 8.2, to digest 4h, and then temperature is down to 38 DEG C, and regulation pH is 6.3, adds wood
Melon protease, 2h is reacted at 58 DEG C, and go out enzyme 3min, is subsequently adding nano titanium oxide, and the amount of addition is rabdosia lophanthide quality 2%,
Regulation pH value is 4.6, and temperature is maintained at 50 DEG C, and 10min is stirred with 250r/min rotating speeds, is then cooled down, and obtains mixed liquor,
Add the absolute ethyl alcohol of mixed liquor quality 80% to be precipitated, filter, collect precipitation, drying is crushed to 800 mesh, obtains final product rabdosia lophanthide
Extract；
3. rabdosia lophanthide extractive and chitosan solution are pressed 1：2 mass ratios uniformly after mixing, are heated to 50 DEG C, are incubated 3h, from
So be cooled to room temperature, using ultrasonication 30s after, neutralized using NaOH, be concentrated into 1/5th of original volume,
Obtain final product.
Further, the wood-fibred uses pine to be obtained for raw material.
Further, the ultrasonic frequency is 30KHz.
Further, the nano silicon micronization, the granularity of nano titanium oxide are 25nm.
By using wood-fibred obtained in pine and the synergy of rosin, enabling to the coating for preparing of the invention to have
Hair porosity higher, its surface contact angle is more than 90 °, so that liquid is more than with the interfacial tension on solid contact interface
Solid interface tension force, liquid can not soak solid, and moisture can be prevented to penetrate into, and therefore, it can cause that the endoscope after application exists
Human secretory liquid can be intercepted in human body to infiltrate through between coating, reduce the life-span of coating；The present invention is by by shitosan and small stream
Yellow grass carries out compound prepared shitosan-rabdosia lophanthide complex, the protonation ammonium in obtained shitosan-rabdosia lophanthide complex molecule
With electropositive, the bacterium with negative electrical charge can be adsorbed so that the negative electrical charge skewness of bacteria cell wall and cell membrane, done
Disturb the synthesis of cell membrane such that it is able to reach antibacterial effect, meanwhile, part shitosan-rabdosia lophanthide complex can be adsorbed carefully
Bacterium, then penetrates and enter into porous cell wall intracellular, the compound with DNA forms stabilization, disturbs archaeal dna polymerase or RNA
The effect of polymerase hinders the synthesis of DNA or RNA, so as to inhibit the breeding of bacterium, the purpose of antibacterial is reached with this；The present invention
Find that coating of the present invention is to Escherichia coli, Candida albicans, staphylococcus aureus and mould by substantial amounts of experimental study
Inhibition is the most notable, also, inhibition to bacterium is substantially better than fungi.
The beneficial effects of the invention are as follows compared with prior art：Endoscope surface antibiotic paint quality prepared by the present invention
Stabilization, with high-efficiency antimicrobial, antiseptic property, while the coating has broad-spectrum sterilization, good resistance to photo and thermal stability, and has
Security, it is environmentally safe the features such as, coating paint film has good adhesive force, hardness, a pliability, absorption of perspiration and corrosion-resistant
Property is excellent.
