The sound transmission effect of the solid is strongest among the solid, the liquid and the gas, the sound transmission of the solid is greatly relieved, and the sound insulation performance of the floor is also greatly enhanced. In actual measurement, the impact sound level of the bare floor is 83 decibels after measurement and calculation, the lowest requirement of civil building sound insulation design specification cannot be met, the impact sound level of the floating floor is 65 decibels after measurement and calculation, the first level of residential building floor impact sound insulation standard is met, and the improvement amount is 18 decibels.
The weighting of the floor between the hotel room and the upper room is normalized, and the impact sound pressure level (laboratory measurement) is less than 55dB under the special standard; the weighted normalized impact sound pressure level (laboratory measurement) of floors at the top of offices and conference rooms in office buildings should be less than 65dB under high demanding standards. And the weighted standardized impact sound pressure level of the reinforced concrete floor slab with the common thickness is about 78dB to 82dB, so sound insulation treatment is required. For the treatment of improving the impact sound insulation of the floor slab, a floating floor slab is generally arranged, namely an elastic cushion layer is arranged in the floor slab structure, so that the impact sound insulation is effectively improved.
An elastic cushion layer applied to the existing floating floor slab structure is a rubber particle sound insulation cushion, the heat conductivity coefficient of the product is high, the composition material is simple, the processing technology is single, and the heat insulation and sound insulation effects of the floating floor slab cannot be improved more conveniently and better; therefore, a preparation method of the heat preservation and sound insulation pad for the LM floating floor is provided to solve the problems
