Preferably, described damping damping block bottom coincide with washing machine internal.
Cement, diamond dust, water mixing can form cement mortar, and cement mortar inherently has good acoustical characteristics, because
This, manufactured balancing weight is also provided with the property of sound absorption；
Sodium acid carbonate can discharge carbon dioxide when being heated to more than 50 DEG C, using this property, can make gained counterweight
Block Surface Creation aperture, so just enhance the sound absorbing capabilities of balancing weight；Carbon can be caused if conventional mode of heating is taken
Sour hydrogen sodium is uneven by thermally decomposing, and influences pore-forming effect, and the present invention uses low frequency microwave heating method, the moisture of slurry in itself by
Heat is so that sodium acid carbonate is heated, due to uniformly having been mixed in whipping process before water and sodium acid carbonate, so can
Make it that pore-forming is uniform.
The high-performance damping material that damping damping block provided by the invention is material A and material B is compounded to form, can be effective
Ground suppresses structure quake and the noise as caused by structure quake, has excellent damping noise reduction effect, while use electric treatment
Mode to material A and material B processing, harmony therebetween can be caused to perform to maximum, damping effect reaches
It is best.
Damping damping block coincide with washing machine internal causes washing machine caused vibrations when work to be directed to
Damping damping block, so as to reduce washing machine caused vibrations and noise when work.
The beneficial effects of the invention are as follows：The invention provides a kind of preparation method of the washing machine counter weight of noise reduction damping,
Can cause prepare balancing weight while solving the problems, such as counterweight, also reduce washing machine at work caused noise and
Vibrations.
