Problems solved by technology

[0002] The existing residential buildings have the disadvantage of poor sound insulation between the upper and lower floors. It is difficult to achieve sufficient sound insulation effect only by relying on the cement board of the floor and the floor laid on the cement board, and the traditional products only distinguish between high-frequency noise and low-frequency noise. , not adequately block the noise of each frequency, thus affecting the quality of life among the residents
[0003] CN100591261C (2010-2-24) discloses a composite floor mat, but it mainly solves the problem that the floor mat cannot completely pick up dirt from people's soles, it is used to lay on the floor, and does not involve the problem of sound insulation

Embodiment 1

[0034] Such as figure 1 As shown, the high-efficiency sound insulation pad includes the first moisture-proof film layer 1 arranged on the bottom layer, the semi-open-cell foam material layer 2 arranged on the middle layer and on the first moisture-proof film layer 1, and the semi-open-cell foam material layer 2 on the fully open foam material layer 3 and the second moisture-proof film layer 4 arranged on the uppermost layer. Among them, the semi-open cell foam material layer 2 is a semi-open cell EPDM foam sponge layer or a semi-open cell PVC foam material layer; the fully open cell foam material layer 3 is a fully open cell polyethylene modified sound insulation material layer; The first moisture-proof film layer 1 and the second moisture-proof film layer 4 are PE film or aluminum film or metal moisture-proof paper layer. The first moisture-proof film layer 1 , the semi-open cell foam material layer 2 , the fully open cell foam material layer 3 and the second moisture-proof ...

Embodiment 2

[0052] Same as Example 1, the difference is that the preparation method of the fully open-cell polyethylene modified sound insulation material includes the following steps in sequence:

[0053] (1) Raw material preparation: 30-75 parts of polyethylene, 10-40 parts of zinc oxide powder, 8-25 parts of magnesium oxide, 10-15 parts of glass fiber, 0.8-1.5 parts of silane coupling agent;

[0054] (2) Primary mixing: mixing the coupling agent, zinc oxide powder, magnesium oxide and glass fiber to obtain primary mixing reactants;

[0055] (3) Full mixing: mixing the initial mixing reactant with the polyethylene to obtain a full mixing mixture;

[0056] (4) Injection molding: Injection molding the full mixture at a temperature of 240-260° C. and a pressure of 40-50 MPa.

[0057] The glue is composed of the following raw materials in parts by weight: 35 parts of phthalic anhydride, 12 parts of triethylene glycol, 18 parts of glutaric acid, 10 parts of butanetriol, 7 parts of zinc oxide ...

Embodiment 3

[0060] Same as Example 1, the difference is that the preparation method of the fully open-cell polyethylene modified sound insulation material includes the following steps in sequence:

[0061] (1) Raw material preparation: 30-75 parts of polyethylene, 10-40 parts of zinc oxide powder, 8-25 parts of magnesium oxide, 10-15 parts of glass fiber, 0.8-1.5 parts of silane coupling agent;

[0062] (2) Primary mixing: mixing the coupling agent, zinc oxide powder, magnesium oxide and glass fiber to obtain primary mixing reactants;

[0063] (3) Full mixing: mixing the initial mixing reactant with the polyethylene to obtain a full mixing mixture;

[0064] (4) Injection molding: Injection molding the full mixture at a temperature of 240-260° C. and a pressure of 40-50 MPa.

[0065] The glue is composed of the following raw materials in parts by weight: 28 parts of phthalic anhydride, 11 parts of triethylene glycol, 17 parts of glutaric acid, 9 parts of butanetriol, 6 parts of zinc oxide...

Abstract

The invention relates to a pad type living supply, in particular to an efficient sound insulating pad. The efficient sound insulating pad comprises a first moisture-proof film layer, a half-open foam material layer, a full-open foam material layer or a cork wood layer, and a second moisture-proof film layer, wherein the first moisture-proof film layer is arranged at the bottom, the half-open foam material layer is arranged in the middle and on the first moisture-proof film layer, the full-open foam material layer or the cork wood layer is arranged on the half-open foam material layer, and the second moisture-proof film layer is arranged at the uppermost top. The sound insulating pad can be used as interior decoration or insulating parts for automobiles, trains, air planes and the like, and can be used on surfaces of buildings to control noise efficiently and can enable the buildings to be beautiful in appearance and high in sound-insulating and noise-reducing efficiency. In addition, the efficient sound insulating pad has the advantage of crashworthiness and can function in protecting safety better, particularly for infants or the old.
