Description

Anaerobically curable resin combination and the strange plug sealant of Weir using it
Technical field
The present invention relates to anaerobically curable resin combinations more crisp with solidfied material, being easy characteristic as micronized. In turn, the present invention relates to used the strange plug sealant of the Weir of above-mentioned anaerobically curable resin combination.
Background technology
Anaerobically curable resin combination is the chemical combination for having free-radical polymerised functional group with (methyl) acrylate etc. Composition of the object as principal component, has the following properties that:It is relatively stable during being contacted with existing oxygen in air, it will not Gelation etc. and kept for a long time with liquid state, if isolating oxygen, hastily carry out Raolical polymerizable.Utilize such property Matter and above-mentioned anaerobically curable resin combination is used for:Screw, bolt etc. are bonded, fix;Gomphosis part it is fixed, viscous It connects, seal;The filling etc. for the stomata that may be generated in cast part.
In addition, as shown in Patent Document 1 like that, anaerobically curable resin combination is chiefly used in engine in automobile component Flange between, the adhering and sealing etc. very filled in of the Weir of cluster engine.
In the case where being sealed the strange plug of the Weir of cluster engine using anaerobically curable resin combination, if anaerobism In hardening resin composition dissolution to engine cool non-freezing solution, then exists and be difficult to cured tendency.Accordingly, there exist dissolutions The gap of the components such as valve or the blade of water pump is entered to the uncured anaerobically curable resin combination in non-freezing solution and is consolidated Change and cause the risk of unfavorable condition.For the problem, Patent Document 2 discloses to include anionic surfactant (methyl) acrylic acid series solidification compound being characterized, even if in solidification compound dissolution to non-freezing solution, it may have high Curability.

The test method used in the embodiment of table 1, comparative example is for example following shown.
The confirmation > of curability of the < in non-freezing solution
The pure SUPER LLC of TOYOTA (are diluted to by 50% non-freezing solution that 40 mass parts are weighed in beaker with pure water Solution after 50%), each 10 mass parts of anaerobically curable resin combination modulated are added thereto.While being stirred with air motor Machine is mixed to be stirred with 300rpm, while be heated up to 100 DEG C, after five minutes, with visual confirmation anaerobically curable resin combination whether there is or not Solidification.The case where solidification will be confirmed, is evaluated as "○", "×" will be evaluated as the case where failing to confirm solidification, by result It is summarized in table 1.
The confirmation > for the solidfied material size that < is obtained in non-freezing solution
The size of solidfied material using microscope to being tested by the curability in non-freezing solution is confirmed.It is based on Following benchmark are evaluated.The results are shown in Table 1.As a result smaller, it is the more preferred.If evaluation result be " in " " small ", making In the case of for the Weir very use of plug sealant, the movement of the valve or blade of water pump will not be prevented, therefore it is preferred that.
Evaluation criteria
Greatly:20mm or more
In:5mm or more and less than 20mm
It is small:Less than 5mm
The brittleness of < solidfied materials, the confirmation > of micronized
Experimenter applies 60N with the sharp stick of hand-hold front end to the solidfied material tested by the curability in non-freezing solution Load, based on following benchmark evaluations destructible of solidfied material.It is explained, in particle after disruption, confirms ruler Very little maximum particle is as object.The results are shown in Table 1.If evaluation result is "○", as Weir very plug sealant In the case of use, the movement of the valve or blade of water pump will not be prevented, therefore it is preferred that.
Evaluation criteria
○:The case where if applied force is destroyed, and particle size is less than 1mm
△:If applied force is destroyed, particle size is the situation of 1mm or more
×:The case where not being destroyed applied force
[table 1]
According to table 1, it is known that it is excellent and solid with the curability in non-freezing solution to belong to the embodiment of the present invention 1~9 Compound is more crisp, is easy the anaerobically curable resin combination of characteristic as micronized.Wherein, fatty acid glyceride has been used The solidfied material that embodiment 6~9 obtains in non-freezing solution is small, be especially suitable for Weir very plug sealant.
In addition, comparative example 1 is the anaerobically curable resin combination without surfactant, but in non-freezing solution after solidification Solidfied material size it is big, and solidfied material is hard, therefore as Weir very plug sealant, there are prevention water pumps Valve or blade movement risk.Comparative example 2~4 is the anaerobically curable resin combination containing anionic surfactant Object, if but the solidfied material applied force after curing in non-freezing solution, be destroyed, the size of particle is 1mm or more, with bravado In the case of Er Qisai sealants, there is the risk of the movement of the valve or blade that prevent water pump.Comparative example 5,6 be containing sun from The anaerobically curable resin combination of subsystem surfactant, the solidfied material after curing in non-freezing solution is hard, therefore with bravado In the case of Er Qisai sealants, there is the risk of the movement of the valve or blade that prevent water pump.
Utilization possibility in industry
The anaerobically curable resin combination of the present invention is suitably applied:Screw, bolt etc. are bonded, fix;Fitting portion Fixation, bonding, the sealing of part;The filling etc. of the stomata generated in cast member.Especially there is the curability in non-freezing solution Excellent and solidfied material is more crisp, is easy characteristic as micronized, therefore extremely effective with sealant as the strange plug of Weir, therefore It is useful in industry.
