Embodiment 1
[0047] Ingredients as follows:
[0048]
[0049] The formulation amounts of the above formulation components are calculated in parts by mass, and the parts by mass specifically refer to the reference quantities calculated by weight of each component under the same unit of measurement, the same below.
[0050] The preparation process is as follows:
[0051] 1) Mix and stir the acrylate polymer emulsion and the silicone-modified acrylate copolymer emulsion according to the specified number of parts, and add all the tackifier emulsion, 50% dispersant, 50% wetting agent, and all bactericides at the beginning of stirring, 50% defoamer. Stir and blend for 20-40 minutes to prepare blended emulsion C.
[0052] 2) Put all the water into an empty mixing container, add the remaining dispersant, wetting agent and defoamer at the beginning of stirring at 100-300r / min, stir for about 10 minutes and start to sift in the formula filler at a uniform speed, Disperse at high speed for 40-6...
Embodiment 2
[0057] Ingredients as follows:
[0058]
[0059]
[0060] The preparation process is the same as in Example 1.
[0061] According to the GB / T 18258-2000 standard test, the nano-modified water-based weather-resistant sound-insulating adhesive obtained in this example has a damping platform with a damping value greater than 0.9 in the temperature range of -5°C to 115°C.
[0062] According to the standard test of GB / T 2791-1995, the arithmetic mean value of the peel strength of the nano-modified water-based weather-resistant sound-insulating adhesive obtained in this example is σT=4.7KN / m.
Embodiment 3
[0064] Ingredients as follows:
[0065]
[0066] The preparation process is the same as in Example 1.
[0067] According to the GB / T 18258-2000 standard test, the nano-modified water-based weather-resistant sound-insulating adhesive obtained in this example has a damping platform with a damping value greater than 0.9 in the temperature range of 5°C to 135°C.
[0068] According to the standard test of GB / T 2791-1995, the arithmetic mean value of the peel strength of the nano-modified water-based weather-resistant sound-insulating adhesive obtained in this example is σT=3.6KN / m.
[0069] The acrylate polymer emulsion and silicone-modified acrylate copolymer emulsion in the formula components are characterized in that at least one of the emulsions is an acrylate emulsion with a LIPN interpenetrating network type core-shell structure, and at least one of them is an acrylic emulsion that has undergone Silicone modified acrylic polymer emulsion. Among them, preferably, the acry...
