[0023] Example
[0024] like Figure 1 and 2As shown, a composite rock wool sandwich panel staggered connection structure includes a plurality of composite rock wool sandwich panels 100, including a front panel and a back panel, a rock wool core material 120 is arranged between the front panel and the back panel, the front panel and the back panel are bonded to the rock wool core material 120 by a two-component polyurethane adhesive, generally the front panel and the back panel are made of steel plates 110, the rock wool core material 120 is sandwiched between two steel plates 110, the steel plates 110 are generally made of stainless steel plates, galvanized color steel plates, aluminum-zinc color steel plates or aluminum-plated steel plates, the rock wool core material 120 is bonded to the steel plates 110 by a two-component polyurethane adhesive, one side of the rock wool core material 120 has a stepped first connection end, and the other side of the rock wool core material has a stepped second connection end arranged in the opposite direction, The first connection end is rotated 180 degrees and overlaps with the second connection end. Preferably, the first connection end is a two-layer step, that is, a part of the first connection end is a protruding rectangular step 122, and the other part of the first connection end is a recessed rectangular groove 121 lower than the rectangular step. Preferably, the rectangular step 122 and the rectangular groove 121 use the middle dividing surface of the first connection end as the parting surface, so that the rectangular step 122 and the rectangular groove 121 are the same volume structure. In the process of manufacturing the rock wool core material 120, it is only necessary to use the middle dividing surface of the rock wool core material 120 to manufacture the connection end, and there is no need to distinguish the size of the rectangular step 122 and the rectangular groove 121, so that two composite rock wool sandwich panels 100 can be assembled together;
[0025] In another embodiment, the rectangular step 122 and the rectangular groove 121 do not use the middle dividing surface of the first connecting end as the parting surface, that is, the rectangular step 122 and the rectangular groove 121 are of different volumes. During the manufacturing process of the rock wool core material 120, it is necessary to distinguish the sizes of the rectangular step 122 and the rectangular groove 121, so that the rectangular step 122 of the first connecting end of the rock wool core material 120 matches the rectangular groove 121 of the second connecting end of the rock wool core material 120, so that two composite rock wool sandwich panels 120 can be assembled together;
[0026] The steel plate 110 is bonded to the rock wool core material 120 by a two-component polyurethane adhesive, and the steel plate 110 has buckles 130 formed by bending or rolling on the sides of the first connection end and the second connection end corresponding to the rock wool core material 120, and the two buckles 130 corresponding to one end of the steel plate 110 are in a staggered structure;
[0027] The buckle 130 includes an end portion of a steel plate that is bent or rolled in sequence toward the inner rock wool core material to form a first bent or rolled portion 131, and then bent or rolled in the opposite direction from the rock wool core material toward the outside and away from the steel plate to form a second bent or rolled portion 132, and then bent or rolled toward the inner rock wool core material and toward the steel plate to form a third bent or rolled portion 133, forming a buckle 130 with a round-shaped structure;
[0028] The buckles at both ends of the steel plate 110 are formed by rolling, which can realize continuous production with high production efficiency, and the product has a consistent shape and stable product quality;
[0029] Preferably, when the buckle 130 is bent or rolled toward the side rock wool core material for the first time, the bending or rolling angle is 90 degrees, so that the steel plate 110 is wrapped on the end surface of the rock wool core material 120, and when the buckle 130 is bent or rolled from the rock wool core material 120 to the outside and away from the steel plate 110 for the second time, the bending or rolling angle is 17-18 degrees, and when the buckle 130 is bent or rolled toward the inner rock wool core material 130 and close to the steel plate 110 for the third time, the bending or rolling angle is 180 degrees, forming a buckle 130 with a round-shaped structure;
[0030] like Figure 3 As shown, when two composite rock wool sandwich panels 100 are assembled together, the protruding portion of the connection end of one composite rock wool sandwich panel 100 is inserted into the concave portion of the other composite rock wool sandwich panel 100, so that the connection ends of the two composite rock wool sandwich panels 100 are staggered and connected;
[0031] The buckle 130 of the panel connection end of one composite rock wool sandwich panel 100 is butted against the buckle 130 of the panel connection end of another composite rock wool sandwich panel 100, and at the same time, the buckle 130 of the back panel connection end is butted against the buckle 130 of the back panel connection end, and then the corresponding fillet 200 is inserted into a pair of buckles 130 to connect the back panels and the panels of the two composite rock wool sandwich panels 100 together;
[0032] The fillet 200 is a U-shaped fillet, and the two sides of the U-shaped fillet 200 are respectively inserted into the buckle 130 of the connection end of a corresponding composite rock wool sandwich panel 100 to form a stable connection structure. The two sides of the U-shaped fillet have a plurality of spaced protrusions 210 protruding inwardly, and the protrusions 210 are buckled and connected with the buckle 130;
[0033] When two composite rock wool sandwich panels 100 are butted together, under the action of pressure, the buckle 130 is bent or rolled from the rock wool core material 120 to the outside and away from the steel plate 110 at an angle of 17-18 degrees to 0 degrees for the second time, forming a mutually parallel structure, which helps the fireproofing, heat preservation and heat insulation effect of the composite rock wool sandwich panel 100;
[0034] Through the staggered connection structure, the composite rock wool sandwich panel 100 can be thinned while maintaining a good fireproof and heat-insulating effect. Generally, the composite rock wool sandwich panel 100 can be made into a 50-75 mm thick metal rock wool composite sandwich panel; and the rock wool core material 120 preferably adopts 150 kg / m 3 Rockwool core material;
[0035] like Figure 4 As shown in the figure, in the thermal insulation test, five composite rock wool sandwich panels 100 are staggeredly connected by buckles 130 at both ends and fillets 200 to form a fire exposure area of 9.06m 2 The sample, the thickness of the composite rock wool sandwich panel 100 is 50mm, the front panel and the back panel are both 0.5mm thick steel plates, and the fillet 200 is also 0.5mm thick steel plates. Then, as shown in the figure, a thermocouple is set at the back-fire surface of the wall panel at the position shown in the figure on the composite rock wool sandwich panel 100. Through the test, it can be known that during the fire test, the temperature measuring points are arranged at the seams of two adjacent composite rock wool sandwich panels and 100mm away from the seams. According to the original structural type, the front panel and the back panel are symmetrically glued. When the fire test is carried out, the temperature transfer is linear transfer, but after changing to a staggered structure, the temperature transfer can become a turning point. The heat insulation performance can be greatly improved, and it has good fireproof and heat insulation effects; and by having buckles 130 at both ends of the rock wool core material 120 and the steel plate, and cooperating with the fillet 200, the grip between the two adjacent composite rock wool sandwich panels 100 can be enhanced, so that the two adjacent composite rock wool sandwich panels 100 can be connected more tightly, and the installation is more convenient. Since the two sides of the U-shaped fillet have protruding blocks 210 protruding inward, in the case of fire, the plate will bend and deform. This type of buckle-type fillet can be firmly stuck with the return-type buckle of the plate, and will not pop out when the plate is deformed by fire.

[0040] 4) The rock wool / fireproof insulation core material of the required specifications is mechanically coated with the automated vector modified PIR active cross-linking liquid on four sides at high pressure, and then transferred to the metal plate cavity where the automated vector high pressure injection equipment has been used to coat the modified PIR active cross-linking liquid on three sides at high pressure.
[0041] 5) Then it merges with the backing material sent in by the upper unwinding equipment platform and enters the entrance of the continuous double-conveyor continuous curing and molding system. During the transmission process, the decorative surface of the decorative layer material is kept facing down; at this time, the line speed is 5 to 10 m / min.
[0042] 6) The double-track continuous molding device has an operating speed of 5 to 10 m / min and an internal temperature of 62 to 69° C. The product is cross-linked and thermally synthesized in the continuous double-track continuous curing molding system;
[0043] 7) The products are cut, stacked and packaged by the automatic cutting and packaging system at the end of the automatic production line, and then transported to the finished product retention area for aging to become the final product.
