Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description is made with reference to the accompanying drawings and detailed description. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the two elements or intervening elements may be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-4, a novel fireproof heat-insulating sandwich panel comprises a panel body, wherein two projections 5 in an annular structure are arranged on one side of the panel body, and a first groove 6 in a trapezoidal structure is formed between the projections 5; a second groove 7 matched with the bump 5 is formed in the other side of the plate body; and bosses 8 in a trapezoidal structure are formed between the second grooves 7. When the plate bodies need to be spliced, the convex block 5 of one plate body is only required to be pressed into the second groove 7 of the other plate body, so that the two plate bodies are fixed, and the splicing structure is simple and convenient.

The plate body sequentially comprises a color steel plate 1, an adhesive layer 2 and a core plate from outside to inside; the core plate comprises a phenolic aldehyde plate 3 and polyurethane plates 4 connected with two sides of the phenolic aldehyde plate 3. The bottom of the first groove 6 and the boss 8 are not covered by the color steel plate 1 and the adhesive layer 2, and the surface of the boss 8 is covered by the non-woven fabric layer 9. A bump 5 and a first groove 6 are provided on the polyurethane plate 4 on one side, and the bump 5 is filled with a polyurethane material. A second groove 7 and a boss 8 are provided on the other side of the polyurethane plate 4, the boss 8 being made of polyurethane. By utilizing the fireproof, waterproof and heat-insulating properties of the phenolic aldehyde plate 3 and the characteristics of light weight and good heat-insulating effect of the polyurethane plates 4 adopted at the two sides of the phenolic aldehyde plate 3, the utility model realizes the fireproof, waterproof and heat-insulating properties and the heat-insulating property between plate-to-plate connections. It should be noted that, the polyurethane boards 4 are connected to both sides of the phenolic aldehyde board 3, and the connection between the board body and the board body, and actually the connection between the polyurethane boards 4 and the polyurethane boards 4, and because the polyurethane has a better thermal insulation property, the thermal insulation performance of the connection between the boards can be ensured. The boss 8 is made of polyurethane, and is exposed outside the color steel plate, and the non-woven fabric layer can protect the boss 8 from being damaged to a certain extent. The boss 8 is not covered by the color steel plate and the adhesive layer, so that the boss 8 has certain elasticity and flexibility outwards. The bottom of the first groove 6 is made of polyurethane materials, is not covered by the color steel plate and the adhesive layer, and also has certain elasticity and flexibility. When the lug 5 of one plate body is pressed and embedded into the second groove 7 of the other plate body, the boss 8 of the other plate body is embedded into the first groove 6, and the thickness of the boss 8 is increased to a certain extent due to the elasticity and the flexibility of the bottoms of the boss 8 and the first groove 6 and the thickness of the boss 8 is increased to a certain extent by the non-woven fabric layer 9, so that the boss 8 is tightly embedded into the first groove 6, and the connection between the plate and the plate is tight.

Furthermore, two side faces of the phenolic aldehyde plate 3 are arranged to be rugged rough faces, so that the contact surface between the phenolic aldehyde plate 3 and the polyurethane plate 4 is increased, and the adhesive force between the phenolic aldehyde plate 3 and the polyurethane plate 4 is increased. As shown in fig. 2 to 3, the texture of both sides of the phenolic board 3, that is, the texture of the rough surface, may be provided in one or more of a triangular saw tooth structure, a rectangular saw tooth structure, and a wave structure. It should be noted that, the polyurethane is in a liquid state, during production, the polyurethane is poured into the color steel plate, the liquid flows to fill the texture of the rough surface of the phenolic aldehyde plate in the color steel plate, so that the phenolic aldehyde plate and the polyurethane are tightly combined, and after the polyurethane is poured, the polyurethane is dried to form the polyurethane.

Further, the bump 5 is a semi-elliptical bump, the second groove 7 is a semi-elliptical groove matched with the bump 5, and the bump 5 can be tightly embedded into the second groove 7.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
