The fire resistance of embodiment 1-5 and comparative example 1-12 casting glue is determined, is characterized with its burning time, each
Embodiment or comparative example take 5 parallel samples to be tested, and the results are shown in Table 1.
Table 1
The burning time for the fire-proof potting compound that embodiment 1-5 is prepared is well below right it can be seen from the result of table 1
The burning time of ratio 1-12 casting glue, illustrating the fire-proof potting compound of the present invention has good fire resistance.When using normal
Advise (comparative example 1) when casting glue component prepares A agent, the burning time of its casting glue being prepared is longer, and with the phase of embodiment 1
Than same without using (comparative example 2) when aluminium hydroxide and TDE, the burning time of its obtained casting glue in A agent
It is longer, about 50s or so, when using aluminium hydroxide in A agent, and without using (comparative example 3) during TDE, even if by hydrogen
The dosage of aluminum oxide improves, and can not equally significantly improve its fire resistance, and its burning time is 35s or so, when using ten in A agent
Bromine diphenylethane, and without using (comparative example 4) during aluminium hydroxide, even if the dosage of TDE is improved, equally can not
Its fire resistance is significantly improved, its burning time is 30s or so, in addition, (such as right when certain component is excessive or very few in A agent
Ratio 5-12), the burning time of its obtained casting glue is fixed still in 25s or so during both uses simultaneously and by dosage
(embodiment 1-5) within the scope of the present invention, now the burning time of casting glue be less than 10s, there is good flame-retardance energy.
The uvioresistant performance of embodiment 1-5 and comparative example 1-12 casting glue is determined, by the power of sample after ultraviolet irradiation
As a result as shown in table 2 the change for learning performance characterizes,.
Table 2
From table 2 it can be seen that after UV is tested, the tensile strength and elongation at break average attenuation of comparative example
19.2-27.1%, and the decay of the casting glue sample of the embodiment of the present invention is only 12.7-14.2%, from data comparison, this hair
The uvioresistant performance of bright sealing also has a certain upgrade.

Fruit is as shown in table 3 and Fig. 1.
Table 3
From the result of table 3 and Fig. 1, when A agent mixes with B agent, because having been used in the A agent of embodiment 1 lower viscous
The base rubber of degree, so the strand of dimethyl silicone polymer is short and more, so crosslinking reaction by linearly dividing with crosslinking agent
During son becomes adult form molecule, the viscosity that macro manifestations come out is lower, and with the change in reaction time, the increase of its viscosity
It is slower than the conventional casting glue A agent of comparative example 1, so in limited usage time, the levelability of casting glue of the invention
More preferably, bubble is easier to overflow at a low viscosity, so the bubble retained is less.
