[0042] The present invention also provides a preparation method of UV polymerization type bulk foam damping material, which comprises the following steps:
[0043] 1) Add the acrylate copolymer and reactive diluent to the reaction kettle, and continuously stir and swell at room temperature to form a uniform acrylic matrix resin;
[0044] 2) Add the photoinitiator to the acrylic matrix resin obtained in step 1), and stir and dissolve evenly;
[0045] 3) adding the nano hollow inorganic particles pretreated by the silane coupling agent in batches to the resin uniformly dissolved in step 2), and stirring so that the nano hollow inorganic particles are evenly dispersed and coated in the resin obtained in step 2), to obtain UV polymerization type bulk foam damping material composition;
[0046] 4) Apply the UV polymerizable body foam damping material composition obtained in step 3) evenly on the release PET film, and irradiate it under ultraviolet light for 3-6 minutes to obtain t...
