The antisepsis and sterilization coating obtained for above-described embodiment one to three carries out coating property Indexs measure, including applies film thickness
Degree, glossiness, adhesive force, hardness, water resistance, resistance to salt water, bacteriostasis rate.Detection method is as follows：
1) measurement of coating thickness
According to GB/T 13452.2-92, film thickness is measured with calibrator, before paint film is completely dried and forms dura mater
It puts, calibrator is placed on specimen surface, it is ensured that then calibrator and instrument vertical rotate dial plate so that calibrator range is big
In film thickness, measurement button is pressed, reading when gauge outfit no longer rotates, then the same plate is surveyed averages three times, error
± 2 μm are not to be exceeded, and test point distance cannot be too close.
2) determination of coating film gloss degree
According to GB 9754-88, after carrying out first high gloss to Grossmeters after the calibration of low luminosity, then to same
One plate difference reading, takes 3 points, and error is not less than 5 units, then averages.

By GB/T 9286-1998, plate is laid flat on the table to guarantee that experimentation template will not deform.It holds and draws lattice
Device, uniformly force evenly draws the scratch of a distance sidewards on template, then keep identical dynamics and speed with before
Scratch standardized section of identical distance again in 90 °, obtain lattice battle array, observe pull-away degree if falling off too severe and use fur
Brush brushes observing effect again along the direction of lattice front.Same plate is at least tested three times at different positions, if tying three times
Fruit difference is more than a unit graduation, then cancels.
4) measurement of hardness of film
Hardness of paint film is measured according to GB/T 6739-2006 pencil method, is ensuring paint film thickness referring to GB/T 13452.2-92
In the case that degree error is little, prepare (soft) pencil each one to 6H (hard) of 6B, using trolley according to pencil from firmly to soft
Sequence promotes at least 7mm with pencil on the surface of film, observes paint film breakage, can dab surface by rubber with convenient
Observation, the pencil hardness that cannot damage film coated surface is hardness of paint film.
5) measurement (rapid deformation experiment) of paint film shock resistance
According to GB/T 20624.2-2006, first weight is promoted to maximum height on conduit and is fixed, then paint film template is put down
It is placed on the supporting surface of experimental provision pedestal, the premise of 15mm is not less than at a distance from ensuring every shock point between edge
Under, weight is discharged, freely falls to it on formed punch.Increase weight, take out template and with amplify sem observation, if template has obviously
Crackle, reduce weight height, repeat the experimental procedure of front, until first observed is less than obvious crackle, record rushing at this time
Hit intensity.
6) measurement of paint film water resistance
Template is immersed in distilled water using immersion test method according to GB/T 1733-93, should not be pasted between template
It closes, observes whether paint film has phenomena such as loss of gloss, whiten, blister, wrinkling, getting rusty daily, if occurring, record time, unit：
It.
7) resistance to salt water
According to GB/T 10834-1989, template is soaked in preparatory prepared 5% sodium-chloride water solution, is seen daily
It examines and loss of gloss whether occurs, change colour, get rusty, blistering, falling off and the breakoff phenomenons such as crackle, when observation, rinse template table with tap water
Face, and specimen surface is gently wiped with soft cloth, in that day for observing breakoff phenomenon, record time, unit：It.
8. mildew resistance
The paint brush is coated on aluminium sheet, template, is placed in experimental situation by twice interval 4h by 90~100 μm of thickness of dry film
Condition：25 ± 1 DEG C, relative humidity 55 ± 3% is lower to conserve 7d.GB/T1741-2007 paint film fungus resistance is surveyed according to national standards
Method for testing, using black box approach, by 9 kinds of mixing moulds, (aspergillus niger, aspergillus flavus, ball hair is bright mould, withered mould, Trichoderma viride, sprouts short
Obstructing mould etc.) strain is seeded on paint film, template is placed on 22~24 DEG C of temperature, humidity>It cultivates, paints in 95% black box within 35 days
Film surface is unchanged.
Performance indicator result after detection is as shown in table 1 below:
