Problems solved by technology

[0002] The existing polyurethane materials with sound-absorbing properties mostly use polyurethane soft foam as the base material, supplemented by simple frame mechanical support to solidify, or directly stick the soft material on the wall. Such polyurethane sound-absorbing panels are basically not It has the mechanical strength to resist deformation, and it is very easy to deform, twist, or even fall off the board surface under pressure or wall deformation over the years
The fire and flame retardant effect of traditional indoor wall panels has high requirements on the thickness of the coating layer and the uniformity of coating, so it is difficult to control
In addition, in the construction of the sound-absorbing board wall, the alignment and leveling of the boards are greatly affected by the flatness of the wall. Aligning and leveling only by experience and feeling is not only troublesome to operate, but also poor in effect

Embodiment 1

[0019] The main structure of this embodiment, such as figure 1 As shown, a polyurethane soft foam composite board with sound-absorbing function includes a polyurethane soft foam layer 1, and sound-absorbing micropores are evenly distributed on the polyurethane soft foam layer 1 . The polyurethane soft foam layer 1 itself has a good sound-absorbing effect, and sound-absorbing micropores are dug out on its surface, which can further increase the specific surface area of ​​the polyurethane soft foam layer, thereby greatly improving the sound-absorbing effect.

Embodiment 2

[0021] This embodiment is further limited on the basis of Embodiment 1, the length of the polyurethane soft foam layer 1 is 800 mm, the width is 550 mm, and the thickness is 20 mm. Here, the structure and shape of the polyurethane soft foam layer 1 are specifically limited, and the polyurethane soft foam layer 1 is rectangular, and not less than two layers, and other equivalent technical shape changes are within the protection scope of the present invention. Other structures involved in the invention are common knowledge in the field and will not be repeated here.

Embodiment 3

[0023] This embodiment is further limited on the basis of the above embodiments, and also includes an anti-aging layer 3, which is a layer made of polyethylene, high-strength polyester, black masterbatch and anti-aging agent through one-time composite processing. Wrapped on the outer surface of the polyurethane soft foam layer 1, wherein the anti-aging layer 3 is fully coated to prolong the service life of the composite board and improve the functionality of the material. Other structures involved in the present invention are common knowledge in the field and will not be repeated here.

Abstract

The invention discloses a polyurethane flexible foam composite board with a sound-absorbing function; the polyurethane flexible foam composite board comprises a polyurethane flexible foam layer; the polyurethane flexible foam layer is uniformly provided with sound-absorbing micropores; the polyurethane flexible foam composite board is simple in structure, low in cost, and the sheet material has sound-absorbing effect, thus prolonging durability, and improving whole intensity of the composite board.

Description

technical field [0001] The invention relates to the technical field of a composite board, in particular to a polyurethane flexible foam composite board with sound-absorbing function. Background technique [0002] The existing polyurethane materials with sound-absorbing properties mostly use polyurethane soft foam as the base material, supplemented by simple frame mechanical support to solidify, or directly stick the soft material on the wall. Such polyurethane sound-absorbing panels are basically not It has the mechanical strength to resist deformation, but it is very easy to deform, twist or even fall off the board surface under pressure or the wall is deformed over the years. The fire and flame retardant effect of traditional interior wall panels has high requirements on the thickness and uniformity of the coating layer, so it is difficult to control. In addition, in the construction of the sound-absorbing board wall, the alignment and leveling of the boards are greatly a...
