Problems solved by technology

Installation is very inconvenient and expensive
[0003] In addition, 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 are only suitable for high-frequency noise and low-frequency noise. Differentiation, different enough to block the noise of each frequency, thus affecting the quality of life among residents
[0004] 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, and is used for laying on the floor, and does not involve air circulation or moisture-proof And other issues

Abstract

The invention relates to a home decoration life article, in particular to a sound insulation cushion. The sound insulation cushion comprises a sound insulation layer and a support layer located below the sound insulation layer, wherein the sound insulation layer is of a sealed facet structure, the support layer comprises a plurality of support units, each support unit is provided with a first sound insulation hook face, a space below the adjacent first sound insulation hook faces between each two adjacent support units forms a first channel, the cross section of each first channel is in a special-shaped hook surface or oval shape, the maximum transverse distance between the adjacent first sound insulation hook faces between each two adjacent support units is 0.5-500mm, the distance between the first sound insulation hook faces adjacent to each support unit is 1-1000mm, and the smallest distance between the surface of each support unit, far away from the sound insulation layer, and an intersection of the sound insulation layer and the first sound insulation hook face of each support unit is 0.3-39mm. The sound insulation cushion can effectively circulate air, prevents damp and mildew, insulates sounds and reduces noise, and is comfortable in foot feeling, and specially suitable for use under a floor in paving mode.

Description

technical field [0001] The invention relates to a household article for decoration, in particular to a sound-insulating pad. Background technique [0002] The two sides of the existing sound insulation mat products are flat. After the floor paving is completed, although the moisture on the ground is prevented from affecting the floor and the floor is protected, the moisture on the ground is kept because the cement floor is completely sealed from the outside. On the concrete floor, it cannot be ruled out. After a long time, the underside of the sound insulation mat will become moldy and breed bacteria in a wet state. If the sound insulation mat is aging or damaged, the moisture and bacteria on the ground will affect the use of the floor and the health of the family. Existing sound insulation mats must be installed with good varieties of floor mats, and the sound insulation mats must not be damaged during installation, and installation needs to be very careful. Because the wi...
