Description

Technical Field

[0001] The utility model relates to a sandwich thermal insulation rock wool board. Background Art

[0002] Common materials for the surface of sandwich panels include plywood, fiberboard, plastic board and metal sheet. The core materials include balsa wood, rubber, acetate fiber, plastic, resin-impregnated paper or cloth, and metal honeycomb structure materials. Rock wool is also a common core material. Rock wool products are internationally recognized as the main energy-saving materials in the "fifth conventional energy" due to their excellent fireproof and thermal insulation properties. Every ton of rock wool products used for insulation in buildings can save at least 1 ton of oil energy per year, which is in line with the trend of low carbon, energy saving and emission reduction. Therefore, as an ideal building insulation material, rock wool is facing unprecedented development opportunities and challenges. The existing sandwich insulation rock wool board still has the following problems in actual use: the rock wool layer and the metal sheet are mostly fixed by bonding structure, but the bonding strength between the rock wool layer and the metal sheet is poor, which makes it easy for the rock wool layer and the metal sheet to separate after long-term use, resulting in poor practicality of the sandwich insulation rock wool board. Summary of the invention

[0004] To achieve the above purpose, the technical solution of the utility model is to design a sandwich insulation rock wool board, including two metal sheets and a rock wool core board arranged between the two metal sheets, wherein the two metal sheets are respectively connected to the rock wool core board through an adhesive layer;

[0005] The surface of the metal sheet facing the rock wool core board is provided with a plurality of mutually parallel glue extrusion convex strips, and first glue containing grooves are respectively provided on both sides of the glue extrusion convex strips;

[0006] The surface of the rock wool core board facing the metal sheet is provided with a plurality of glue injection grooves corresponding to the glue extrusion convex strips one by one, the glue injection grooves are used for inserting the corresponding glue extrusion convex strips, and a second glue containing groove corresponding to the first glue containing groove is opened on the groove wall of the glue injection groove.

[0007] Preferably, the plurality of rubber extrusion convex strips are arranged at equal intervals.

[0008] Preferably, the first glue containing groove extends along the length direction of the glue extrusion convex strip, and the second glue containing groove extends along the length direction of the glue injection groove.

[0009] Preferably, the adhesive layer is formaldehyde-free glue.

[0010] Preferably, the cross-section of the glue extrusion convex strip is arc-shaped, and the cross-section of the glue injection groove is square.

[0011] Preferably, the metal panel is a galvanized steel plate.

[0012] The advantages and beneficial effects of the utility model are: providing a sandwich thermal insulation rock wool board, which has a reasonable structure and effectively improves the connection firmness between the rock wool core board and the metal sheet, thereby improving the practicality of the sandwich thermal insulation rock wool board. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the utility model.

[0014] Figure 2 yes Figure 1 Enlarged view of point A in the middle. DETAILED DESCRIPTION

[0015] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0016] The technical solution specifically implemented in this utility model is:

[0017] like Figure 1 and Figure 2 As shown, a sandwich insulation rock wool board comprises two metal sheets 1 and a rock wool core board 2 arranged between the two metal sheets 1, wherein the two metal sheets 1 are connected to the rock wool core board 2 through adhesive layers 3 respectively;

[0018] The surface of the metal sheet 1 facing the rock wool core board 2 is provided with a plurality of mutually parallel glue extrusion convex strips 4, and first glue containing grooves 5 are respectively opened on both sides of the glue extrusion convex strips 4;

[0019] The surface of the rock wool core board 2 facing the metal sheet 1 is provided with a plurality of glue injection grooves 6 corresponding one to one with the glue extrusion convex strips 4, the glue injection grooves 6 are used for inserting the corresponding glue extrusion convex strips 4, and the groove wall of the glue injection groove 6 is provided with a second glue containing groove 7 corresponding to the first glue containing groove 5.

[0020] Furthermore, the plurality of rubber extrusion convex strips 4 are arranged at equal intervals.

[0021] Furthermore, the first glue containing groove 5 extends along the length direction of the glue extrusion convex strip 4 , and the second glue containing groove 7 extends along the length direction of the glue injection groove 6 .

[0022] Furthermore, the adhesive layer 3 is formaldehyde-free glue.

[0023] Furthermore, the cross section of the glue extrusion convex strip 4 is arc-shaped, and the cross section of the glue injection groove 6 is square.

[0024] Furthermore, the metal panel 1 is a galvanized steel plate.

[0025] When assembling a sandwich thermal insulation rock wool board according to the utility model: firstly, an adhesive layer 3 is applied to the surfaces of both sides of a rock wool core board 2 respectively, and bonding glue 8 is injected into a bonding groove 6, wherein the bonding glue is formaldehyde-free glue; then a metal sheet 1 is attached to the surface of the rock wool core board 2, so that the metal sheet 1 contacts the adhesive layer 2, and a glue extrusion convex strip 5 is inserted into the corresponding glue injection groove 6, and the bonding glue 8 in the glue injection groove 6 is squeezed into a first glue containing groove 5 and a second glue containing groove 7 by the glue extrusion convex strip 5, and when the bonding glue 8 filled in the first glue containing groove 5 and the second glue containing groove 7 is cured, a card strip is formed between the first glue containing groove 5 and the second glue containing groove 7, so that the rock wool core board 2 and the metal sheet 1 are not easily separated, thereby improving the connection firmness between the rock wool core board 2 and the metal sheet 1, so as to improve the practicality of the sandwich thermal insulation rock wool board.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
