Single composition or composite components do not obtain desired technical effect, are having been surprisingly found that after many experiments, triallyl isocyanide
The collaboration of two kinds of urea acid esters, polyethyleneglycol diacrylate compositions is used in combination, and can be realized the purpose of the present invention, can make the present invention
Sealant quickly forms bridged bond that is a large amount of and being evenly distributed, the 3 D stereo reticular structure being built into surface drying solidification process
It is form compact and stable, and then improve the strength physical performance of glue-line；If the change of the composition of crosslinking agent or/and content in the present invention,
Will lead to beneficial effects of the present invention cannot realize well.
(2) coupling agent: gamma-aminopropyl-triethoxy-silane is more common a kind of silane in sealant preparation production
It is coupling agent, but is applied in raw materials for production system of the present invention as independent composition, and improper, it is difficult to reaches the present invention
Purpose, subsequent applicant is dexterously by gamma-aminopropyl-triethoxy-silane, rare-earth coupling agent (3-5) in mass ratio: (1-2)
Collaboration utilizes, and unexpectedly obtains corresponding technical effect, physical property, in terms of all have and significantly mention
It rises；If the change of the composition of coupling agent or/and content in the present invention, will lead to beneficial effects of the present invention cannot be good
It realizes.
(3) promotor: applicant is had found by many experiments, using tetramethyl thiourea, accelerant C hartwellB-
515.71W is according to mass ratio (1-2): it is more suitable for that raw material of the invention prepares body that (2-3), which merges obtained mixed type promotor,
System, the coordinated effect of tetramethyl thiourea, accelerant C hartwellB-515.71W can greatly improve reaction and promote efficiency,
It is effectively improved the comprehensive performance of finished product sealant；If the change of the composition of promotor or/and content, will lead in the present invention
Beneficial effects of the present invention cannot be realized well.
(4) antioxidant: likewise, the selection of antioxidant composition of the present invention is not arbitrarily to obtain or there is originally,
It is also what applicant was obtained by many experiments, in development, applicant has been surprisingly found that the collaboration of antioxidant 1010, irgasfos 168
It is used in combination, is more suitable for the preparation reaction system of sealant of the present invention, uses above two composition according to mass ratio (3-
5): (2-3), which merges, to be utilized, and can improve the inoxidizability, stability and service life of glue-line significantly；If resisting in the present invention
The composition of oxygen agent or/and the change of content, will lead to beneficial effects of the present invention cannot realize well.
Certainly, because of the requirement of the mentality of designing and goal of the invention of sealant of the present invention, remaining of the invention component selection and
Content selection is obviously also non-obvious, and those skilled in the art combine the prior art that can readily occur in absolutely not.This
Have further embodiment in the preparation method of sealant of the present invention, in conjunction with the embodiment of the present invention it can be seen that, system of the invention
Raw material is added using I-III three step design in Preparation Method by several times in batches, and step is simple and orderly, rather than uses the prior art normal
Rule are added at one time (such as comparative example 6), and this technique is the special proportion phase with sealant raw materials for production component of the present invention
It adapts to, only uses this technique, just can guarantee the excellent characteristics for the sealant finally prepared.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features.It is all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
