30min is kept in the syringe heater of HL-YR123.Hot melt adhesive pours into rapidly DV-II+pro at molten fluid at this time
In sleeve in Viscometer viscosimeter viscosity apparatus, 10.0 ± 0.2g is weighed, temperature is set at 120 DEG C and is kept for 20 minutes,
So that hot melt adhesive internal temperature uniformly and deaeration.At a temperature of 120 DEG C, the constant temperature melt viscosity of hot melt adhesive is measured.
(2) adhesive strength:
Be 25mm wide in specification, on the glass plate of 100mm long, 5mm thickness, on the direction grown along glass plate, and away from
Uniformly coating width is 1mm at two edge 6mm, long to be greater than 25mm, with a thickness of 2 above-mentioned hot melt adhesive adhesive tape of 0.3mm.Use 0.15mm
The steel wire of diameter controls the thickness of adhesive tape, at once with the glass plate of second piece of same specification with the direction of vertical first piece of glass plate
Two pieces of glass plates are glued together, and with 1.5 Kgfs pressing weld 15 seconds, with the high voltage mercury lamp radiation 10s of 1000W, so
It is placed on the adhesive strength tested respectively after 15min and 72h in climatic chamber, the respectively initial adhesive strength of the sample and end
Viscous intensity.
(3) tensile strength and elongation at break:
Reference standard ASTM D638 sample preparation, glue sample are made into the wide 6mm of sheet type, thick 0.5mm, dumbbell shaped.Sample is existed
(humidity 60%, 25 DEG C of temperature) places 72h in climatic chamber, carries out further according to ASTM D638 standard the method to glue sample
Tensile strength and elongation at break test, tensile speed 100mm/min, test temperature are 25 DEG C.Gained tensile strength and disconnected
It splits elongation and is denoted as TS respectively0And EL0。
(4) weatherability is tested: reference standard ASTM D638 sample preparation, glue sample are made into the wide 6mm of sheet type, thick 0.5mm,
Dumbbell shaped.By sample, (humidity 60%, 25 DEG C of temperature) places 72h in climatic chamber, is then placed in high/low temperature hydrothermal aging
Atmospheric exposure test 240h is carried out in case, which is carried out automatically by ageing oven, and the specific steps are elder generations in 80 DEG C of temperature, humidity
10h is tested under the conditions of 80%, then tests 10h under conditions of -40 DEG C, humidity 80%, is then alternately gone down until total examination
Testing the time is 240h.Carry out tensile strength and elongation at break test again after the test, tensile speed 100mm/min is surveyed
Trying temperature is 25 DEG C.Gained tensile strength and elongation at break are denoted as TS respectively1And EL1.The weatherability of each sample is stretched strong by it
Change rate (α) and elongation at break change rate (β) are spent to characterize, and calculation formula is as follows:
1 embodiment and comparative example properties of product test value of table
As can be seen from Table 1, the initial adhesive strength of product and viscous eventually in the embodiment of the present invention 1~5 and embodiment 6~9
Intensity is higher by 424%~581% and 8.6%~36.7% than comparative example product F respectively, shows that Light Curing can significantly improve
Its initial adhesive strength, and the addition of chemical modifier also has certain good effect to its raising for gluing intensity eventually.On the other hand, originally
The tensile strength of product and elongation at break are higher by than comparative example product (F) respectively in inventive embodiments 1~5 and embodiment 6~9
4.7% and 21.5% or more, especially product A~E test post-tensioning intensity and elongation at break through high/low temperature hydrothermal aging
Change rate is also more much smaller than product F, shows that the toughness of product and weather-proof also can be improved by the way that chemical modifier is added in the present invention
Property.
