Description
Technical field
This utility model is related to coating test instrunment technical field, and in particular to self-healing coatings crack repairing performance is tested
Instrument.
Background technology
Self-healing coatings are a kind of new coatings for having an automatic healing ability, and nearly more than ten years have developed rapidly, multiple
Field is widely used.This kind of material is just widely studied at present, is developed this coating by with very high Jing
Ji value.But with developing rapidly for this new material, the test mode of self-healing coatings, method of testing, test equipment instrument
Device does not all obtain improving well and development.Cause test project all can not state well selfreparing elastomeric material from
Repairing performance, invent it is a kind of can simulate dry formed and repair state equipment be very important.
A critically important performance of self-healing coatings is exactly to test the crack self-healing time.Artificially coating entered before test
Row manufacture crack, becomes the key technology in test performance.The various states such as fracture length, the width of manufacture, can serious shadow
Ring the test result to the later stage.The reason for causing building coating layer to ftracture species is very more, mainly have base layer structure cracking, it is greasy
Sublayer cracking, base treatment is improper, coating dehydration is too fast etc., and reason causes.Coating is flexible material, and base material cracking can make coating
Film produces crack, and coating film receives pulling force in engineering, and there is certain width in the crack of film self-assembling formation（0.2~
0.5mm）.Some meetings are bigger.Fracture width is accurately manufactured, stress during phenomenon simulation crack occurrence is to design this
The important references factor of class testing instrument.
Mostly manufacture crack using patterning method at present.
1st, single blade directly cuts manufacture crack：
Row are such as：The crack of 5mm length is directly cut out at test specimen center with the wallpaper knife of 0.5mm thickness, is then split at this
Sew on the certain hydraulic pressure of loading to be tested.Secondary method is easy to operate simple, and error is little；But the crack that secondary method cuts out, by
In the resilience of flexible paint itself, cause fracture width to be substantially not reaching to desired width, load during test after hydraulic pressure,
Leakage very little at crack, is unfavorable for embodying the self-repairability of coating.And be not inconsistent with the fracture width of appearance in engineering.
2nd, double blade cutting manufacture crack：
Row are such as：The crack of 5mm length is cut out at test specimen center with the wallpaper knife of two panels 0.5mm thickness is simultaneously neat, in two blades
The distance of point of a knife is 0.5mm, and the crack of 0.5mm width can be cut out on film, is then loaded on this crack certain
Hydraulic pressure is tested.The method is easy to operate simple；But the fracture width for cutting out can not be controlled accurately, and fracture width is general
0.5mm can be more than, and the width for cutting out every time is inconsistent.Load after hydraulic pressure during test, leakage is very big at crack, also unfavorable
In the self-repairability for embodying coating.And be to dig up 0.5mm*5mm sizes from painting center membrane in this crack manufacture process
Coating, so as to produce crack.The crack caused by film disappearance, carries out state and does not meet with actual engineering crackses.Survey
The accuracy of examination film self-healing properties also can heavy discount greatly.
