Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of insulation boards, and more particularly relates to a high-strength flame-retardant extruded insulation board. BACKGROUND

[0002] The extruded insulation board is a common insulation material in engineering, which is usually made of polystyrene resin as raw material plus other raw and auxiliary materials and polycontents, through heating, mixing, injecting catalyst, and then extruding and forming.

[0003] The most prominent feature of the general extruded insulation board is good flame retardance and good thermal insulation, however, with the improvement of engineering quality requirements, many projects begin to require the extruded insulation board to have certain strength and sound insulation performance. In this regard, the common practice is to sandwich a sound insulation layer and a reinforcing layer between two extruded insulation boards. In this structure, the reinforcing layer is usually a planar net structure, and in order to adhere firmly with the sound insulation layer and the extruded insulation board, cement mortar or other adhesives are usually filled in the mesh holes, which leads to complex process, and the filled cement mortar or other adhesives also leads to the increase of product weight and the rise of material cost.

[0030] Please refer to Figures 1 to 3 The high-strength flame-retardant extruded insulation board provided by the embodiments of the present application will be described. A high-strength flame-retardant extruded insulation board comprises:

[0031] Two single-layer insulation boards, each single-layer insulation board is provided with a plurality of convex strips with a trapezoidal cross section on the inner side, and the gap between adjacent convex strips forms a receiving groove with an inverted trapezoidal cross section, the groove bottom width of the receiving groove is greater than the top width of the convex strip; the two single-layer insulation boards are arranged opposite to each other, and the convex strips of one single-layer insulation board are aligned with the receiving grooves of the other single-layer insulation board;

[0032] At least one reinforcing strip, each reinforcing strip is located in any receiving groove of the two single-layer insulation boards and is arranged along one waist plane of the receiving groove, so that the remaining space of the receiving groove forms a matching groove matching the convex strip;

[0033] A sound insulation layer is embedded between the inner surfaces of the two single-layer insulation boards and is clamped by the corresponding convex strips and matching grooves of the two single-layer insulation boards.

[0034] Compared with the prior art, the high-strength flame-retardant extruded insulation board of the embodiments of the present application discards the traditional mesh reinforcing layer, and does not need to fill cement mortar or adhesive into the mesh, thereby reducing the product weight and cost;

[0035] The two single-layer insulation boards of the present application have the same structure and can be produced using one mold, thereby reducing the production cost; and the sound insulation layer is embedded between the two single-layer insulation boards, which can adjust the size error of the convex strips and receiving grooves of the two single-layer insulation boards, thereby reducing the precision requirement for the single-layer insulation board and being more conducive to production;

[0036] The reinforcing strip is attached to one waist plane of the receiving groove, so that the size of the reinforcing strip in the thickness direction of the high-strength flame-retardant extruded insulation board is increased, so that a smaller reinforcing strip can play a greater reinforcing role, and the high-strength flame-retardant extruded insulation board can withstand a greater force in the thickness direction (for the high-strength flame-retardant extruded insulation board bending in the direction of the reinforcing strip).

[0037] In actual engineering, the strength requirements of the insulation board in two perpendicular directions parallel to the insulation board are not the same, usually the strength requirement of the insulation board in one direction is higher, and the strength requirement in the other direction is not high. The strength of the high-strength flame-retardant extruded insulation board in the direction of the reinforcing strip and the strength perpendicular to the direction of the reinforcing strip are different. When used, the direction of the high-strength flame-retardant extruded insulation board is set so that the direction of the reinforcing strip is the same as the direction required by the engineering to meet the engineering requirements.

[0038] In specific implementation, the two single-layer insulation boards can be made of polystyrene resin material and processed by using a mold. The outer surface of the single-layer insulation board is flat, and a trapezoidal protruding strip is arranged at a certain distance on the inner surface. The reinforcing strip is flat, which can be made of aluminum alloy strip or polycarbonate strip, etc. The sound insulation layer can be made of a rigid member, and the sound insulation layer is processed into a curved shape matching the curved gap between the inner surfaces of the two single-layer insulation boards, and then embedded in the curved gap between the inner surfaces of the two single-layer insulation boards; the sound insulation layer can also be made of a common flexible filling material with sound insulation performance, so as to be conveniently filled in the curved gap between the inner surfaces of the two single-layer insulation boards. According to actual requirements, the material of the sound insulation layer needs to have corresponding fireproof performance. The parts of the high-strength flame-retardant extruded insulation board can be connected by bonding or by means of connecting pieces, and a frame can be arranged on the outer periphery of the high-strength flame-retardant extruded insulation board to fix the two single-layer insulation boards and increase the strength.

[0039] Please refer to Figure 1 , as a specific embodiment of the high-strength flame-retardant extruded insulation board provided by the present application, at least two reinforcing strips are arranged, at least one reinforcing strip is arranged in the receiving groove of one single-layer insulation board, and at least one reinforcing strip is arranged in the receiving groove of the other single-layer insulation board.

[0040] In the embodiment, the two single-layer insulation boards are reinforced by the reinforcing strips to ensure the strength of the two single-layer insulation boards.

[0041] Please refer to Figure 1 , as a specific embodiment of the high-strength flame-retardant extruded insulation board provided by the present application, the two adjacent reinforcing strips are arranged in the receiving grooves of the two single-layer insulation boards.

[0042] In specific implementation, the first reinforcing strip is arranged in the receiving groove of the lower single-layer insulation board, the second reinforcing strip is arranged in the receiving groove of the upper single-layer insulation board, the third reinforcing strip is arranged in the receiving groove of the lower single-layer insulation board, and the fourth reinforcing strip is arranged in the receiving groove of the upper single-layer insulation board, and so on. The uniformity of the strength of the two single-layer insulation boards is ensured.

[0043] Please refer to Figure 1As a specific embodiment of the high-strength flame-retardant extruded insulation board provided in the present application, the cross section of the reinforcing strip is a parallelogram, and the long side surface of the reinforcing strip is attached to the waist plane of the accommodating groove, one short side surface is attached to the bottom surface of the accommodating groove, and the other short side surface is coplanar with the top surface of the adjacent convex strip.

[0044] In the present embodiment, after the reinforcing strip is installed into the accommodating groove of the single-layer insulation board, the four side surfaces of the reinforcing strip can be attached to other parts, thereby ensuring the close fit between the components.

[0045] Please refer to Figure 1 and Figure 2 As a specific embodiment of the high-strength flame-retardant extruded insulation board provided in the present application, the sound insulation layer is a flexible component.

[0046] In the present embodiment, after the sound insulation layer is placed between the two single-layer insulation boards, the sound insulation layer can be tightly attached to the two single-layer insulation boards through clamping, and the processing is more convenient.

[0047] Please refer to Figure 1 and Figure 2 As a specific embodiment of the high-strength flame-retardant extruded insulation board provided in the present application, the sound insulation layer includes two layers of mesh cloth and sound-absorbing cotton sandwiched between the two layers of mesh cloth.

[0048] In the present embodiment, the two layers of mesh cloth are used to prevent the sound-absorbing cotton from scattering and to keep the sound-absorbing cotton flat. Moreover, after the mesh cloth on both sides is bonded to the single-layer insulation board, the strength of the two single-layer insulation boards can be increased.

[0049] Please refer to Figure 1 As a specific embodiment of the high-strength flame-retardant extruded insulation board provided in the present application, the reinforcing strip is an aluminum alloy component or a polycarbonate component. The weight of the reinforcing strip is reduced.

[0050] Please refer to Figure 3 As a specific embodiment of the high-strength flame-retardant extruded insulation board provided in the present application, the high-strength flame-retardant extruded insulation board is rectangular with a length greater than a width, and the convex strips are arranged along the length direction.

[0051] In the present embodiment, on the one hand, it is convenient for the user to distinguish the direction of the convex strip and the reinforcing strip, and on the other hand, due to transportation, installation, and other processes, the high-strength flame-retardant extruded insulation board is easily subjected to a large force in the length direction. Arranging the convex strip and the reinforcing strip along the length direction can avoid the high-strength flame-retardant extruded insulation board being broken in the length direction.

[0052] In actual engineering use, the external fixed frame can be matched, and the high-strength flame-retardant extruded insulation board is reinforced in the width direction to a certain extent through the fixed frame, so as to make up for the weakness of the high-strength flame-retardant extruded insulation board in the width direction.

[0053] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
