The formation > of the open reel 101 of <
First, the formation of the open reel 101 involved by present embodiment is described with reference to Figure 12.
Figure 12 is the stereogram that the outward appearance of the open reel 101 represented involved by present embodiment is formed.As shown in figure 12, open reel 101 possesses: rope form containing fluorophor resin 120 and reel 30.
(the containing fluorophor resin 120 of rope form)
The light-emitting component 13 being equipped on luminescent device containing fluorophor resin 120 sealing of rope form.Specifically, rope form has the silicones 21 of wavelength conversion material and fluorophor 22 to be shaped to rope form containing fluorophor resin 120 by dispersed.At this rope form containing in fluorophor resin 120, as described later, be added with in its formation process make 2 times crosslinked after the plasticizer that declines of the modulus of elasticity of silicones 21.
The formation method > containing fluorophor resin 120 of < rope form
Next, the formation method containing fluorophor resin 120 of rope form is described with reference to Figure 13.
Figure 13 (a) ~ Figure 13 (d) is the concise and to the point figure of an example of the formation method containing fluorophor resin 120 representing the rope form shown in Figure 12.
As shown in Figure 13 (a), first, to being formed with 1 crosslinked powder of silicones 21 and the powder of fluorophor 22 carries out dry mixing, till admixture becomes evenly, thus mixture of powders 24 is obtained.
Secondly, as shown in Figure 13 (b), in mixture of powders 24, add the plasticizer 23 of modulus of elasticity decline (secondary strategic point makes viscosity decline) making the silicones 21 after being cross-linked for 2 times.In addition, will describe later in detail about plasticizer 23.Then, the mixture of powders 24 being added with plasticizer 23 is put in twin-screw extruder device 37, with lower than 2 crosslinking temperature T

Next, with reference to Figure 14, the detailed content containing the plasticizer 23 added in the formation process of fluorophor resin 120 at rope form is described.
Silicones 21 after crosslinked by 1 time is at room temperature T
0under there is higher viscosity, the melting caused by heating is low, stick together (attachment) property in addition and wettability also low.Thus, when heating, silicones 21 insufficient fusion each other, becomes the state that gap is many.When silicones 21 is formed and is cross-linked and hardens for 2 times in this state, seal easily cracking containing fluorophor resin 120 of light-emitting component 13.In order to suppress the generation of crackle, the modulus of elasticity of the silicones 21 after being cross-linked for 2 times is preferably made to decline.
So, in the present embodiment, in the mixture of powders 24 that the powder of silicones 21 and the powder of fluorophor 22 are carried out dry mixing and obtained, add a small amount of aqueous plasticizer 23 that the modulus of elasticity of the silicones 21 after being cross-linked for 2 times is declined.
This plasticizer 23 also can make the crosslink density of silicones 21 decline.Thereby, it is possible to make the modulus of elasticity of the silicones 21 after being cross-linked for 2 times suitably decline, suppress to seal cracking containing fluorophor resin 120 of light-emitting component 13.
In addition, the viscosity that plasticizer 23 also can make to be formed with 1 crosslinked silicones 21 declines.Thus, rope form become easy containing the processing etc. of fluorophor resin 120, in addition by making mixture of powders 24 have intermiscibility, thus can be seamlessly easy to concentrate by silicones 21 be one.
As this plasticizer 23, such as, be principal component with silicon, suitably can adopt without functional group's property silicone oil or monofunctional silicone oil etc., also can react with matrix organosilicon (Matrixsilicone), also can not react.Plasticizer 23 is suitably selected matchingly with the characteristic of luminescent device.
Figure 14 is that the presence or absence of the interpolation representing the plasticizer 23 shown in Figure 13 is caused, the table of the viscosity of silicones 21 and the change of modulus of elasticity.Shown in Figure 14 2 times crosslinked before the viscosity of silicones 21 of (1 cross-linked state) and 2 times crosslinked after the modulus of elasticity of silicones 21.
As shown in figure 14, by adding (11 % by weight) plasticizer 23 to silicones 21, thus till the viscosity at 25 DEG C of places of the silicones 21 before being cross-linked for 2 times can be made to drop to 1/3 degree.In addition, the viscosity at 120 DEG C of places of the silicones 21 before being cross-linked for 2 times can be made to drop to 1/100 degree till.
Although the value of the viscosity of silicones 21 changes according to the addition of plasticizer 23, is roughly 1 × 10 at 25 DEG C
4pas ~ 1 × 10
5pas is 1 × 10 at 120 DEG C
2pas ~ 1 × 10
4pas.In addition, if the addition of plasticizer 23 represents with the weight ratio of plasticizer 23 relative to silicones 21, be then preferably 5 ~ 20 % by weight, be more preferably 8 ~ 15 % by weight, more preferably 11 % by weight degree.
And then, by adding plasticizer 23 to silicones 21, thus can make 2 times crosslinked after 25 DEG C of silicones 21 at modulus of elasticity from ~ 5 × 10
7pa drops to ~ and 1 × 10
7pa.In addition, can make 2 times crosslinked after 125 DEG C of silicones 21 at modulus of elasticity from ~ 1 × 10
7pa drops to ~ and 2 × 10
6pa.
So, by increasing plasticizer 23, thus can make 2 times crosslinked before the viscosity of silicones 21 decline, the processing etc. containing fluorophor resin 120 being therefore formed with 1 crosslinked rope form becomes easy.
In addition, by adding plasticizer 23, thus the crosslink density of silicones 21 declines, therefore, it is possible to make the modulus of elasticity of the silicones 21 after being cross-linked for 2 times at 25 DEG C and 125 DEG C decline.Thereby, it is possible to suppress to seal cracking containing fluorophor resin 120 of light-emitting component 13.
The effect > of < execution mode 3
As more than, the open reel 101 involved by present embodiment possess to the addition of in formation process make 2 times crosslinked after the rope form of plasticizer 23 that declines of the modulus of elasticity of silicones 21 containing fluorophor resin 120.
By adding the plasticizer 23 making the modulus of elasticity of the silicones 21 after being cross-linked for 2 times decline, thus can suppress to seal cracking containing fluorophor resin 120 of light-emitting component 13.
