Example Embodiment
[0039] Example 1:
[0040] As attached figure 1 As shown, the preparation thickness is 3mm and the density is 50kg / m 3 The foam sheet with a thickness of 5mm and a density of 30kg / m 3 The thickness of the 5mm sheet is compounded in the middle of the two layers of 3mm, so that the upper layer 1 has a thickness of 3mm, the middle layer 2 has a thickness of 5mm, and the lower layer 3 has a thickness of 3mm, a total thickness of 11mm, and an average density 40kg / m 3 The three-layer composite polyethylene foam sound insulation layer 8.
[0041]The construction method 1 is adopted during construction, and the specific structure is as image 3 Shown:
[0042] 1. Before the construction of sound insulation materials, clean the ground and try to avoid debris on the ground, which may cause damage to the sound insulation materials;
[0043] 2. The sound insulation material should be trimmed in advance. If there is any defect, it should be cut with a knife. The joints should be welded with a...
Example Embodiment
[0050] Example 2:
[0051] Through three extruders and a three-layer co-extrusion die, an unfoamed sheet with a certain thickness and width is obtained, and then heated and foamed to obtain a surface layer and a core layer with different thicknesses and densities.
[0052] The schematic diagram of the structure of this embodiment is attached figure 2 As shown, in this embodiment, a foam material with a structure of upper and lower layers formed by one-time foaming is used, wherein the thickness of the upper surface layer 4 is 6mm, and the density is 100kg / m 3 ; The thickness of the core layer 5 is 8mm, and the density is 50kg / m 3 ; The thickness of the lower skin layer 6 is 6mm, and the density is 50kg / m 3 , The overall thickness is 20mm.
[0053] The specific construction method is except that the skirting line is processed by using the sound insulation layer to bypass the wooden floor or other decorative ground, and the skirting line is fixed to the wall, and the bottom surface...

[0054] Example 3:
[0055] Preparation thickness is 4mm, density is 70kg / m 3 The foam sheet with a thickness of 7mm and a density of 40kg / m 3 The foam sheet with a thickness of 7mm is compounded in the middle of two layers of 4mm sheets, so that the upper layer 1 has a thickness of 4mm, the middle layer 2 has a thickness of 7mm, the lower layer 3 has a thickness of 4mm, and a total thickness of 15mm. Composite polyethylene foam sound insulation layer.
[0056] The specific construction method is the same as in Example 1.
