Step 5, acquisition sample infrared spectroscopy, the infrared light map of the frame glue after being solidified take out ATR after the completion of detection
Attachment with solidify after frame glue.
Step 6, the infrared spectroscopy that raw rubber is tested using method similar with the above method.Test the infrared spectroscopy of raw rubber
Method and abovementioned steps the difference lies in that before raw rubber is put on base station by sample operation mouth, first raw rubber is smeared
After Jin Jingshang, and fitting sample operation mouth, continues to use after small flow nitrogen is inflated 2 minutes to confined space and stop
Only.
Step 7, the curing degree that frame glue is determined according to the infrared spectroscopy of frame glue and raw rubber after solidification.
In another embodiment, determine that the curing degree of frame glue specifically may be used according to the infrared spectroscopy of frame glue and raw rubber after solidification
To include: to be integrated respectively to the characteristic group peak in the infrared spectroscopy of frame glue sample and raw rubber after solidification, then into
Row calculates, and calculation formula is as follows:

Figure 12 is target signature functional group peak (epoxy group) for the frame glue sample that existing and provided by the invention test method detects
Map is compared, Figure 13 is the target signature functional group peak for the frame glue sample that existing and provided by the invention test method detects
The comparison map of (acrylic).
Wherein, in Fig. 8 it can be seen from a kind of existing target signature function for the frame glue sample that test method detects
Group peak (epoxy group) map correction area be 0.0176, do not correct area be 1.9178, range be (923.775,
896.775), baseline is (923.775,896.775).A kind of existing test method detects it can be seen from Figure 10
The correction area of target signature functional group peak (acrylic) map of frame glue sample is 0.0114, and not correcting area is 0.8653,
Range is (1646.980,1627.695), and baseline is (1646.980,1627.695).
Spectral line 911 indicates target signature functional group peak (epoxy group) that the present invention detects in Figure 12, and spectral line 912 indicates existing
Target signature functional group peak (epoxy group) for thering is technology to detect.The target that the present invention detects it can be seen from Figure 12 is special
It levies functional group peak (epoxy group) peak intensity and is significantly better than the prior art.Spectral line 921 indicates the target that the present invention detects in Figure 13
Characteristic group peak (acrylic), spectral line 922 indicate target signature functional group peak (acrylic) that the prior art detects.By scheming
As can be seen that target signature functional group peak (acrylic) peak energy that the present invention detects enough integrates very well in 13, and the prior art
Map can not integrate, and target signature functional group peak (acrylic) peak intensity that the present invention detects is significantly better than the prior art.
The infrared spectroscopy of the prior art will receive the influence of air and moisture it can be seen from Fig. 6-Figure 13, lead to map
Generate zigzag, can not integrate, while peak intensity is low, test accuracy is low, the present invention can well to characteristic group peak into
Row integral calculation, significant effect, the precision for improving the frame glue curing degree being calculated is higher, is conducive to promote glass substrate patch
Leakproofness and reliability after conjunction improve the quality of display product.
