Description
Technical field
It is the present invention relates to a kind of keeping quality excellent and assign good curability by light, particularly ultraviolet irradiation
Photo-curable perfluoroalkyl polyether system gel combination, its curing, its gel solidification thing and the gel system for having used the solidfied material
Product.
Background technology
At present, using the divalent holo-fluorine polyester with 2 alkenyls in 1 molecule as host, containing with being bonded to silicon atom
The fluoride gel composition of organic hydrogen diene polysiloxanes and platinum group metal series catalysts of hydrogen atom be known, its is usual
Formed at a temperature of 60~150 DEG C by the heating of 30~180 minutes or so with excellent resistance to chemical reagents, resistance to molten
Agent and the perfluoroalkyl polyether system gel solidification thing (patent document 1) of low-moisture permeability.
The addition curable perfluoroalkyl polyether system gel combination of above-mentioned being heating and curing property uses the platinum group metal system of catalytic amount
Catalyst, but from the consideration of the reasons such as good catalyst activity is shown, platinum alkenyl silica is used generally in curing catalysts
Alkane complex compound.But because the catalyst activity is high, particularly when making the composition of a liquid type, in order to obtain sufficiently
Keeping quality is, it is necessary to add reaction controlling agent.As a result, to make curability during its solidification slow in the case where room temperature etc. is than relatively low temperature
It is blunt, on the other hand, following predicament be present：When reducing the addition of reaction controlling agent to improve the curability under low temperature, nothing
Method obtains sufficient keeping quality.Therefore, actual conditions are first, sufficient amount to be added in order to obtain desired keeping quality
Reaction controlling agent, on curability, sufficient curability is obtained by implementing the heating of high temperature.
But when under above-mentioned use condition solidifying composition, it is difficult to applied to the material for having used heat resistance deficiency
The part of material or the component that can not heat because in size and performance the problem of etc., in addition, heating treatment step is necessary,
Thus, the speed that molding procedure when having to molding procedure on production line being set to intermittent mode, control production be present is asked
Topic.
Go for being unable to heater and can improve that manufacture efficiency is such, keeping quality is excellent therefore, it is desirable to develop
Perfluoroalkyl polyether system gel combination different and that good curability is shown in the case where room temperature etc. is than relatively low temperature.
On the other hand, in silicone elastomer material, existing known Photocurable composition be use by 230~
400nm UV light irradiations make the photoactivation type hydrosilylation catalysts of activation of catalyst, have filling when not carrying out light irradiation concurrently
The Photocurable composition (patent document 2 and patent document 3) of good curability when the keeping quality and light irradiation that divide.
