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

[0018] The main structure of this embodiment, such as figure 1 As shown, a polyurethane soft foam composite board with high structural strength includes at least two layers of polyurethane soft foam layer 1 and a supporting frame 2. The supporting frame 2 is welded by metal alloy frames evenly and tightly arranged, and thermally compounded on polyurethane Between the soft foam layer 1, the thickness of the support frame 2 is 20-30mm, and the support frame 2 is an aluminum alloy mesh frame composed of a square, so that the composite board has good mechanical rigidity and can effectively withstand pressure and resist wall deformation. Moreover, the combination of the mesh skeleton is simple, and the contact surfaces of each frame are flat and straight. After the positive force is applied, it will not produce lateral force like other complex shape skeletons, and can effectively maintain the soft two-layer polyurethane itself. The overall shape of the soft foam layer.

Embodiment 2

[0020] This embodiment is further limited on the basis of embodiment 1, the thickness of the support frame is 25 mm or 20 mm, and other structures involved in the present invention are common knowledge in the field, and will not be repeated here.

Embodiment 3

[0022] 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 soft foam composite board with high structural strength. The polyurethane soft foam composite board comprises at least two polyurethane soft foam layers and a support skeleton, wherein the support skeleton is formed by uniformly and tightly arranging and welding metal alloy frames, and is hotly compounded between the polyurethane soft foam layers; and the support skeleton has a thickness of 20-30 mm. The polyurethane soft foam composite board is simple in structure and low in cost, has a sound absorbing effect, and improves the whole strength while prolonging the service cycle.

Description

technical field [0001] The invention relates to the technical field of a composite board, in particular to a flexible polyurethane foam composite board with high structural strength. 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...
