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

[0016] The main structure of this embodiment, such as figure 1 As shown, a polyurethane soft foam composite board that is easy to assemble includes a polyurethane soft foam layer 1, a metal alloy mesh skeleton 2, and an anti-aging layer 3. The anti-aging layer 3 is made of polyethylene and an anti-aging agent through a composite process. Its six sides are coated on the outer surface of the composite board core 4 formed by the polyurethane soft foam layer 1 and the metal alloy mesh skeleton 2, wherein the polyurethane soft foam layer 1 itself has a good sound absorption effect, and on its surface Setting the sound-absorbing micropores can increase the specific surface area of ​​the polyurethane soft foam and greatly improve the sound-absorbing effect; the full coating of the anti-aging layer 3 can prolong the service life of the composite board and improve the functionality of the material.

Embodiment 2

[0018] This embodiment is further limited on the basis of Embodiment 1. A connecting tenon 6 is provided on a group of adjacent sides of the composite board core 4, and a connection tenon 6 matching the shape of the connecting tenon 6 is provided on the other group of adjacent sides of the composite board core 4. The tenon and groove 7, wherein the shape of the connecting tenon 6 can be cylindrical, and the shape of the tenon and groove 7 matches the shape of the connecting tenon 6, which is convenient for the upper and lower positioning between adjacent boards and between the insulation boards when the insulation boards are spliced. The whole is leveled internally and externally, and the tenon connecting the tenon 6 makes the action of inserting into the tenon groove 7 smoother and easier to disassemble. Other structures involved in the present invention are common knowledge in the field and will not be repeated here.

Embodiment 3

[0020] This embodiment is further defined on the basis of the above embodiments, the flexible polyurethane foam layer 1 has a rectangular structure and has two layers. The polyurethane soft foam layer 1 itself has a good sound-absorbing effect, and sound-absorbing micropores can be provided on its surface to further increase the specific surface area of ​​the polyurethane soft foam layer, thereby further improving the sound-absorbing effect. Other structures involved in the present invention are common knowledge in the field and will not be repeated here.

Abstract

The invention discloses a conveniently-assembled polyurethane flexible foam composite board. The conveniently-assembled polyurethane flexible foam composite board comprises a polyurethane flexible foam layer, a metal alloy netted framework and an anti-aging layer which is a thin layer formed by combined machining of polyethylene and an anti-aging agent for once. Six surfaces of the conveniently-assembled polyurethane flexible foam composite board are wrapped by the outer surface of a composite board core made by the polyurethane flexible foam layer and the metal alloy netted framework.The conveniently-assembled polyurethane flexible foam composite board has following beneficial effects: the conveniently-assembled polyurethane flexible foam composite board is simple in structure and low in cost; the board has a sound-absorbing effect; usage period is prolonged; overall strength of the composite board is improved; and fire-proof flame-retardant performance is obtained;

Description

technical field [0001] The invention relates to the technical field of a composite board, in particular to a flexible polyurethane foam composite board that is easy to assemble. 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 affect...
