In dysprosium, neodymium fluoride, ErF_3 films, dysprosium fluoride, potassium fluoride, strontium fluoride, samaric fluoride, neodymium fluoride, sodium fluoride, barium fluoride and cerium fluoride
One or more mixtures.
Due to modification AF coating material wide adaptability of the invention, plated by optical vacuum, it can be in metal or plasthetics
On plate the film with a thickness of 150~200 nanometers, be higher by 50 nanometers of the coating limit of existing modified AF material, thus, this hair
Bright modification AF coating material is applied on metal or plasthetics, can reach better waterproof, antifouling, anti-fingerprint performance.
The present invention plates AF material, progressive by optical vacuum on plastic cellphone shell by taking plastic cellphone shell as an example
It can test, as follows:
One, adhesive force is tested: being cut out 1*1mm cross grid pattern on coating by cross-cut tester, is used 3M610 adhesive tape
Be attached on notch, after standing 60S, tear adhesive tape rapidly, adhesive force is divided into 0,1,2,3,4,5 five grade, adhesive force be greater than or
Equal to 4 grades Shi Hege.
Two, wearability test:
(1), rubber test: EF-74 rubber is installed on friction durability machine, the load of 500g is applied, with 30 times/
The speed of minute recycles friction 1000 times on determinand surface back and forth, and whether observation test surfaces leak show-through paint or ground.
(2), RCA paper tape is tested: weight 175g, and using wear-resisting 200 circle of cleaning machine test of paper tape, surface printing 30 is enclosed, observation
The whether show-through paint of test surfaces or ground.
(3), alcohol abrasion test: full 95% absolute alcohol packet is dipped in the 500g counterweight head of friction durability machine with pure cotton cloth
It is upper that (area for wrapping measuring head after cotton is about 1cm2), with 30 beats/min of speed, the stroke of 20mm or so, in sample table
Face wipes 1000 times back and forth, and whether observation test surfaces leak show-through paint or ground.
Three, hardness test: being tested on pencil hardometer using the pencil (Mitsubishi's board) of 5H, 4H, 3H, 2H, hard according to pencil
The sequence of degree, by gradually testing to soft firmly, until pen tip will not scratch coating surface completely, test is every time with 10cm/s
Speed in coating surface once to being pushed forward 10mm (being applied to load on pen tip is 1kgf), by sentencing firmly to soft sequence
Disconnected, first will not leave behind the pencil of scratch, as final " pencil hardness ".
Four, anti-scratch performance: the sample levels after film are placed, will be added with certain mass counterweight (sand face is towards sample)
It is uniformly streaked from surface, to there is the anti-scratch performance that the minimum mass of obvious scratch indicates the sample of coat coating.
Five, anti-fingerprint performance test:
(1), marker is tested: being marked on panel with marking pen, then the remaining marking is observed in wiping.
(2), resistance to hand perspiration test: taking pH value is 4.7 synthetic perspiration, and drop 3~5 places determinand on determinand surface
It in constant temperature and humidity machine (75 DEG C of test temperature, humidity 90%RH), is taken out after 24H, visually judges whether tester surface has
Paint, blistering or discolouration phenomena.
(3), resistance to cosmetics test: taking a certain amount of cosmetics Nivea, Atrix to be applied to determinand surface, will be to be measured
Object is placed in constant temperature and humidity machine (75 DEG C of test temperature, humidity 90%RH), visually judge tester surface whether have paint,
Blistering or discolouration phenomena.
Six, corrosion resistance is tested: determinand is placed in spray test instrument (using 5% salt, 95% fresh water 35 ± 1.1
DEG C, 85%RH) in, it is taken out after salt spray resistance 48H, whether test sample has corrosion/verdigris/corrosion/metachromatism.
Seven, ageing-resistant test: radiation/UV exposure test should test Sa: the ground simulation sun according to IEC60068-2-5
Whether radiation, UV illumination 96H, testing product change colour, deform, crack.
Eight, paint aging is tested: under 85 degree, boiling 30 minutes, being placed under room temperature cooling 2H, whether is observation coating
There are blistering, corrugation, obscission；Adhesive force 4B or more is qualified, and confirmation print is removed after only attaching 90s with 3 #610 after printing test
Whether there is or not fall off.
Nine, it shakes wear-resisting test: preparing 3 parts of RKF 10K (yellow cone) and 1 part of RKK15P (green pyramid), altogether
About 15L is added in grinding groove, and the mixture of 1L water and 6ml medical fluid is added, the mixture of 500ml water and 6ml medical fluid, often
Half an hour checks that sample is primary, and the discontinuous shape 1*1mm of 0.5H sharp edge/acute angle/round edge wears 1 banner word and is not allow for visible mill
Damage.
Test result is as follows table 1
Table 1
For test result of the invention, compared with conventional imitative ceramic product, adhesive force of the invention is greater than standard water
Flat, wearability cycle-index is higher, has reached higher wear-resisting property, and after surface treated, the anti-scratch performance for imitating ceramics is good,
Preferable anti-fingerprint, anti-pollution, waterproof, antiageing effect can also be reached.
Above disclosed is only presently preferred embodiments of the present invention, cannot limit rights protection model of the invention with this
It encloses, therefore according to equivalent variations made by scope of the present invention patent, is still within the scope of the present invention.
