2. and (3) permanent adhesion testing: according to the measurement of the GB/T4851-2014 method, a standard adhesive tape with the thickness of 25mm multiplied by 100mm is attached to a stainless steel plate, the upper end of the standard adhesive tape is aligned with a standard line, the redundant part at the lower end of the standard adhesive tape is cut off, a compression roller with the thickness of 2kg is used for rolling back and forth for 3 times, the stainless steel plate attached with a sample is vertically hung on a test rack after being placed for a period of time, the test rack is not shaken, a weight with the thickness of 1kg is hung below the test rack, and the time that the adhesive tape falls represents the magnitude of the pressure-sensitive adhesive holding power;
3. test of 180 ° peel strength: according to GB2792-2014, a standard adhesive tape with the thickness of 25mm multiplied by 200mm is attached to a stainless steel plate wiped clean by alcohol, a compression roller with the thickness of 2kg is used for rolling back and forth for 3 times, the stainless steel plate is placed at room temperature for a period of time and then is tested by a peeling force tester, each sample is measured for more than three times, and finally, an average value is taken; the peeling speed is 300 mm/min;
4. light transmittance: solidifying colloid into a sample wafer of 5cm multiplied by 5cm, and then testing the light transmittance with the wavelength of 270nm-800nm by an optical transmittance instrument (LS117) of science and technology Limited company in Shenzhen City, wherein OD is an abbreviation of optical density, which indicates the optical density absorbed by an object to be detected and is a proper term in a detection method, and a detection unit is represented by OD value, and OD is lg (1/trans), wherein trans is the light transmittance value of the object to be detected;
5. solvent resistance: the pressure-sensitive adhesive tape was heated on a heating stage at 65 ℃ and then adhered to an aluminum foil, which was immersed in a dimethyl carbonate solvent and placed in an oven at 65 ℃ for a prescribed time. Taking out the aluminum foil to observe whether the adhesive tape is warped or falls off, peeling the adhesive tape by using tweezers, and observing whether the adhesive surface is swelled;
6. high temperature resistance: respectively placing the test pieces prepared by the pressure-sensitive adhesive tape according to the GB/T2792 and GB/T4851 and 2014 standards into a 150 ℃ high-temperature oven for 24 hours, and then detecting the peel strength;
7. water resistance: tested according to ASTM D557 standard.
The test results are shown in table 1:
as can be seen from Table 1, the ultraviolet curing foaming adhesive prepared in the embodiments 1-6 of the invention has a large annular initial adhesion at a wavelength of 270-800nm, and the adhesive has the advantages of good permanent adhesion, low light transmittance, good solvent resistance, good temperature resistance, low water absorption and the like, and the key point is that manual operation is replaced, so that the ultraviolet curing foaming adhesive has a good application prospect.
Comparative example 1 has no foaming agent added, and has low annular initial adhesion and insufficient permanent adhesion, which shows that the use of the foaming agent is beneficial to improving the initial adhesion and the permanent adhesion; the test results of comparative examples 2 and 3 show that the foaming agent and the foaming aid affect the viscosity and water absorption; the test results of comparative example 4 show that too high a ratio of photocurable resin and blowing agent results in a decrease in adhesion and temperature resistance; the test result of the comparative example 5 shows that the 180-degree peel strength, 0.4mm light transmittance and high temperature resistance of the product are deteriorated due to the excessively high addition of the foaming agent and the foaming auxiliary agent; the test result of the comparative example 6 shows that the addition of the foaming agent and the foaming auxiliary agent is too low, so that the holding power, 180-degree peel strength and high temperature resistance of the product are obviously reduced; the data of comparative examples 7 and 8 show that when the photoinitiator was added in too much or too little, the product properties of the reactions in the tables were significantly reduced; comparison of comparative example 9 with example 1 shows that changing the order of addition of blowing agent and blowing aid also has an effect on the adhesion.
