Embodiment 1
[0040] A kind of preparation method of interlayer film of laminated glass, described preparation method comprises following preparation steps:
[0041] 1) Put 94.95 parts by weight of MMA, 0.05 parts by weight of ABVN and 5.00 parts by weight of hydroxypropyl acrylate in a 250mL flask and mix them evenly, and place them in an oil bath for prepolymerization by heating at 80°C until a large amount of After bubbling for 10s, the reaction is completed to obtain an intermediate solution, and the intermediate solution is degassed under low pressure and put into an ice-water bath to cool down until the wall of the flask becomes cold, and the prepolymerized solution is obtained after degassing;
[0042] 2) Inject the pre-polymerization solution obtained in step 1) between the two glass layers of the laminated glass with good sealing of the silica gel strip;
[0043] 3) Put the laminated glass filled with the pre-polymerization solution in a water bath at a constant temperature of 60°C...
