Description
Technical field
The application advocates right of priority 2006-281233 number to Japan's patent application,, by reference its integral body is added in this specification sheets at this.
The present invention relates to a kind of polysulfide curable composition, more specifically, a kind ofly under hot and humid degree environment, also can guarantee to operate essential work-ing life and the solidification compound that is particularly useful as sealing material of the foaming can suppress to solidify significantly simultaneously the time even relate to.
Background technology
Past, in polysulfide curable composition, especially in hot and humid degree environment, owing in the isocyanate group of curing agent component and the operating environment or the reaction of moisture in the member produce carbonic acid gas and then surface exceedingly the expansible foamed phenomenon become that design is gone up, problem on anti-waterborne, the bonding strength.In addition, the polysulfide sealing material is used in the less seam of capacity such as stone seam or watt seam mostly, and the sealing material amount that time per unit can be constructed is few, so in matrix and the work-ing life that needs after solidifying agent mixes more than 2 hours.
But, wait and adjust speed of response if carry out the increment of catalyzer in order to suppress the foamed phenomenon in the hot and humid degree environment, then the mixed thickening rate of matrix/solidifying agent accelerates, and can not guarantee necessary work-ing life, thereby operability is reduced significantly.In addition, if thereby reduced catalyst makes speed of response slack-off in order to guarantee work-ing life, and then the reacting phase of isocyanic ester and moisture increases over the ground, brings detrimentally affect to foaminess.
Under such present situation, as the means that suppress to foam, guarantee work-ing life, open the spy and to have proposed to make it to contain the curing catalysts that constitutes by tertiary amine and/or organometallic compound among the flat 10-121031 (patent documentation 1) and, but have that storage back effect lowers, can not obtain problem such as effect of sufficient in the hot and humid degree environment in full summer as the phosphate ester acid that solidifies retarding agent.In addition, open among the 2000-273438 (patent documentation 2) the spy, propose to limit the specific isocyanate compound and the ratio of isocyanate group/mercaptan, made it contain the retarding agent that responds, but still be difficult to adjust in full summer the harsh and unforgiving environments balance of work-ing life and foaminess.
