Examples
Embodiment 1
[0038] The raw materials were weighed according to the components and parts by weight of the sound-absorbing coating in Example 1 in Table 1. Under the condition of stirring, dissolve the dispersant, preservative, filler and polysiloxane in 4 parts of water and stir well. Then add acrylic resin, film-forming aid and 4 parts of water under stirring condition and stir evenly. Then divide the weighed hollow plastic balls into 5 equal parts and add them in 5 times. After each addition, they need to be stirred evenly before adding the remaining hollow plastic balls. Finally, add the remaining 4 parts of water and stir evenly to obtain the sound-absorbing coating. Finally, put the prepared sound-absorbing paint into the hopper of the spray gun, move the spray gun in one direction, and spray on the inner surface of the cover plate 5 step by step for 4 times, and dry to obtain the sound-absorbing coating 51 .
Embodiment 2
[0040] The raw materials were weighed according to the components and parts by weight of the sound-absorbing coating in Example 2 in Table 1. Under the condition of stirring, dissolve the dispersant, preservative, filler and polysiloxane in 6 parts of water and stir evenly. Then add acrylic resin, coalescent and 6 parts of water under stirring condition and stir evenly. Then divide the weighed hollow plastic balls into 3 equal parts and add them in 3 times. After each addition, they need to be stirred evenly before adding the remaining hollow plastic balls. Finally, add the remaining 6 parts of water and stir evenly to obtain the sound-absorbing coating. Finally, put the prepared sound-absorbing paint into the hopper of the spray gun, move the spray gun in one direction, and spray on the inner surface of the cover plate 5 step by step twice, and dry to obtain the sound-absorbing coating 51 .
Embodiment 3
[0042] The raw materials were weighed according to the components and parts by weight of the sound-absorbing coating in Example 3 in Table 1. Under the condition of stirring, dissolve the dispersant, preservative, filler and polysiloxane in 8 parts of water and stir evenly. Then add acrylic resin, film-forming aid and 8 parts of water under stirring condition and stir evenly. Then divide the weighed hollow plastic balls into 4 equal parts and add in 4 times. After each addition, it needs to be stirred evenly before adding the remaining hollow plastic balls. Finally, add the remaining 8 parts of water and stir evenly to obtain the sound-absorbing coating. Finally, put the prepared sound-absorbing paint into the hopper of the spray gun, move the spray gun in one direction, and gradually spray five times on the inner surface of the cover plate 5, and dry to obtain the sound-absorbing coating 51.
