Abstract
The invention discloses the rapid analysis method of a kind of paint solvent resistance to shrinkage cavity test, belong to chemical technology field.The rapid analysis method of a kind of paint solvent of the present invention resistance to shrinkage cavity test quickly succinct, non-environmental-pollution, with a high credibility；Directly use test check, it is not necessary to coating, tinplate do spray test, it is to avoid the interference factor of coating and tinplate；Use sample bottle Direct Test sample, it is to avoid the interference of some factors such as dust, greasy dirt that manual operation brings；Eliminate environmental disturbances factor, the principle directly differed according to the surface tension of different material, produce bubble by vibrations and observe the length of foam time and quickly judge whether sample material contain the material of the easy shrinkage cavities such as silicone oil.
Description
Technical field
The invention belongs to chemical technology field, specifically, particularly relate to the quick of a kind of paint solvent resistance to shrinkage cavity test
Analysis method.
Background technology
Coating, paint, resin diluent shrinkage cavity to be carried out test judges whether sample contains shrinkage cavity
Divide and then judge that sample is the most qualified.Existing detection method is as follows: with dimethylbenzene or designated solvent dissolved samples, dripped by solution
On tinplate, at external coating coating and be dried after air-drying, observe and on film, whether there occurs that shrinkage cavity etc. is abnormal the most existing
As, thus judge whether sample contains shrinkage cavity composition.This determination method is the longest, needs one and a half hours；To detection
Environmental requirement is high, during application, brush board, and base material factor, horse oralia pre-treatment, compressed air drying degree and operation management
All test can be produced impact etc. factor；Requiring that judgement person has stronger professional skill, there is multiple uncertain factor in the method,
Detection sample is convenient not, directly perceived.
Summary of the invention
In order to solve the problems referred to above, the invention discloses the rapid analysis method of a kind of paint solvent resistance to shrinkage cavity test, this
Kind of method quickly succinct, non-environmental-pollution, with a high credibility.
The present invention implements by the following technical programs:
The rapid analysis method of a kind of paint solvent resistance to shrinkage cavity test, comprises the steps:
A, the sample taking a 8.0g are positioned in the glass dish of cleaning, make sample be distributed in the end of glass dish uniformly
Portion；
B, put down gently the glass dish filling sample to be placed in the constant temperature oven of 150 DEG C and dry；
C, after sample is dried completely, take out glass dish and be placed on asbestos board or heat-resistant board and naturally cool to room temperature,
Glass dish after cooling reinjects the high-purity aromatic solvent of 5ml, allows the examination that its dissolved dilution glass dish inwall has been dried
Sample；
D, after abundant dissolved dilution, the sample in glass dish is poured into ground tool plug glass specimen bottle in, axially use hands
Shake vibration 10 times, stands and observes the foam time that dissolves each other completely, if less than or equal to 5s, foam time i.e. judges that sample shrinkage cavity is tested
Qualified, on the contrary defective.
Preferably, described glass dish is 50ml glass dish, and described ground tool plug glass specimen bottle is 10ml, described glass dish
All cleaned by acetone with ground tool plug glass specimen bottle.
Compared with prior art, the invention has the beneficial effects as follows:
The rapid analysis method of a kind of paint solvent of the present invention resistance to shrinkage cavity test quickly succinct, non-environmental-pollution, credibility
High；Directly use test check, it is not necessary to coating, tinplate do spray test, it is to avoid the interference of coating and tinplate
Factor；Use sample bottle Direct Test sample, it is to avoid the interference of some factors such as dust, greasy dirt that manual operation brings；Row
Except environmental disturbances factor, the principle directly differed according to the surface tension of different material, produce bubble by vibrations and observe
The length of foam time quickly judges whether to contain in sample material the material of the easy shrinkage cavities such as silicone oil.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is the most further described in detail:
The rapid analysis method of a kind of paint solvent resistance to shrinkage cavity test, comprises the steps:
A, the sample taking a 8.0g are positioned in the glass dish of cleaning, make sample be distributed in the end of glass dish uniformly
Portion；
B, put down gently the glass dish filling sample to be placed in the constant temperature oven of 150 DEG C and dry；
C, after sample is dried completely, take out glass dish and be placed on asbestos board or heat-resistant board and naturally cool to room temperature,
Glass dish after cooling reinjects the high-purity aromatic solvent of 5ml, allows the examination that its dissolved dilution glass dish inwall has been dried
Sample；
D, after abundant dissolved dilution, the sample in glass dish is poured into ground tool plug glass specimen bottle in, axially use hands
Shake vibration 10 times, stands and observes the foam time that dissolves each other completely, if less than or equal to 5s, foam time i.e. judges that sample shrinkage cavity is tested
Qualified, on the contrary defective.
Preferably, described glass dish is 50ml glass dish, and described ground tool plug glass specimen bottle is 10ml, described glass dish
All cleaned by acetone with ground tool plug glass specimen bottle.
Embodiment:
50ml glass dish, 10ml ground tool plug glass specimen bottle are cleaned rear stand-by by acetone；Take the examination of a 8.0g
Sample is positioned in the glass dish of cleaning, makes sample be distributed in the bottom of glass dish uniformly；The glass dish filling sample is put down gently
It is placed in the constant temperature oven of 150 DEG C and carries out drying about 15 minutes, after sample is dried completely, take out glass dish and be placed on asbestos board
Or naturally cool to room temperature on heat-resistant board, the glass dish after cooling reinjects the high-purity aromatic solvent of 5ml, makes it molten
Solve the sample that dilution glass dish inwall has been dried；After abundant dissolved dilution into, the sample in glass dish is poured ground tool plug glass
In glass sample bottle, axially shake with hands vibration 10 times, stand and observe the foam time that dissolves each other completely, if foam time is less than or equal to 5s
I.e. judge sample shrinkage cavity pass the test, on the contrary defective.
The rapid analysis method of a kind of paint solvent of the present invention resistance to shrinkage cavity test quickly succinct, non-environmental-pollution, credibility
High；Directly use test check, it is not necessary to coating, tinplate do spray test, it is to avoid the interference of coating and tinplate
Factor；Use sample bottle Direct Test sample, it is to avoid the interference of some factors such as dust, greasy dirt that manual operation brings；Row
Except environmental disturbances factor, the principle directly differed according to the surface tension of different material, produce bubble by vibrations and observe
The length of foam time quickly judges whether to contain in sample material the material of the easy shrinkage cavities such as silicone oil.
In sum, only presently preferred embodiments of the present invention, not it is used for limiting the scope that the present invention implements, all depends on
Equalization change and the modification that shape, structure, feature and spirit described in scope of the invention as claimed is done, all should be included in this
In the right of invention.
