Description
Technical field
The present invention relates to field of rubber technology, more particularly, to a kind of test method for simulating rubber bloom.
Background technology
Rubber in process, adds substantial amounts of additive, such as filler, reinforcing agent, plasticizer, colouring agent, rush
Enter agent, age resistor etc., according to the difference of rubber compounding, the ratio shared by various additives is also not quite similar.
Additive has certain solubility in rubber, and when exceeding or reaching solubility soon, rubber is in environment
When (temperature, humidity, illumination etc.) changes, phenomena such as being easy for occurring bloom (including discoloration, oil spout, dust, wax spray).Draw
It is more to play this bloom of rubber, discoloration, the factor of oil spout, natural aging checking expends very much time, money and energy, but current rubber
Glue industry is also without the accelerated test procedures of more unified checking rubber bloom.
Therefore, a kind of test method for fast and accurately verifying rubber bloom is researched and developed, is that those skilled in the art urgently solve
Technical problem certainly.
The content of the invention
In view of the shortcomings of the prior art, the technical problems to be solved by the invention are to provide a kind of experiment for simulating rubber bloom
Method, it can fast and accurately verify rubber bloom phenomenon.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
The test method of the simulation rubber bloom, comprises the following steps：
1) rubbery sample is put into the vial for being contained with water, a rubbery sample part is immersed in the water, and rubbery sample is another
A part not immerse；
2) and then bottle cap, sealing container, or blow-by is covered tightly but need to ensure that water is not oven-dried in 70 hours；
3) 70-90 DEG C is heated to, carries out being incubated 20-70 hours in this temperature, the outward appearance of rubbery sample is observed after insulation.
Wherein, the water in the vial is deionized water.
The rubbery sample hanging is in vial.
The rubbery sample must not be in contact with vial inwall.
Rubbery sample in the vial on subsurface rubbery sample and liquid level >=30mm.
Deionized water in the vial accounts for the 1/2-3/4 of vial volume.
The present invention compared with prior art, has advantages below：
The aging of rubber parts is catalyzed by warming and humidifying method, accelerates the bloom phenomenon of rubber, it can be effectively quick, accurate
Really, and it is replicable checking rubber bloom phenomenon, test method is simple and quick, without expending too many time and cost.
Brief description of the drawings
The content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is test chamber schematic diagram of the present invention.
Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation.
As shown in figure 1, the test method of the simulation rubber bloom, comprises the following steps：
Rubbery sample is put into the vial for being contained with water, a rubbery sample part is immersed in the water, and rubbery sample is another
Part not immersed；
Then bottle cap, sealing container, or blow-by are covered tightly but need to ensure that water is not oven-dried in 70 hours；
70-90 DEG C is heated to, carries out being incubated 20-70 hours in this temperature, the outward appearance of rubbery sample is observed after insulation.
Wherein, the water in vial is deionized water.Rubbery sample is hung in vial, and rubbery sample must not be with glass
Bottle inwall is in contact, and avoids local temperature excessive.
Deionized water in vial accounts for the 1/2-3/4 of vial.In vial on subsurface rubbery sample and liquid level
Rubbery sample >=30mm, experiment is accurate.
Specific embodiment is：
Experimental condition：
Temperature：70 DEG C, 80 DEG C, 90 DEG C
Time：22h, 46h, 70h
Sample：Strip exemplar, length ＞ 60mm
Operating procedure：
Sample is put into the vial for having about 2/3 deionized water, and aliquot is immersed in deionized water, and aliquot is not
Immerse, then cover tightly bottle cap, sealing container.Subsurface specimen length >=30mm, specimen length >=30mm on liquid level, examination
Sample must not contact with chamber wall.
At temperature as defined in keeping temperature, observed respectively in 22h, 46h, 70h sample outward appearance (whether have oil spout, dust,
Phenomena such as wax spray, discoloration).
Test evaluation：
Rubber strip ocular estimate is carried out according to following phenomenon：
1 grade：Sample Non Apparent Abnormality
--- (oil spout, dusted, wax spray etc.) without precipitate, no discoloration
--- precipitate or discoloration unobvious.
2 grades：There are the phenomenon of bloom or discoloration, water surface part Non Apparent Abnormality in part in immersion water.
3 grades：There is the phenomenon of similar bloom part Non Apparent Abnormality in immersion water, water surface part.
4 grades：Part has the phenomenon of similar bloom with water surface part in immersion water.
The aging of rubber parts is catalyzed by warming and humidifying method, accelerates the bloom phenomenon of rubber, it can be effectively quick, accurate
Really, and it is replicable checking rubber bloom phenomenon, test method is simple and quick, without expending too many time and cost.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employ the present invention design and technical scheme carry out various unsubstantialities improvement, or it is not improved will
The design and technical scheme of the present invention directly applies to other occasions, within protection scope of the present invention.
