[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.
[0024] As Figures 1-5 shown, a lightweight thermal insulation and fireproof composite board includes a composite board body 1. One end of the composite board body 1 is fixedly connected with a first T-shaped column 2 in the middle. A second T-shaped groove 4 is opened on one side of one end of the composite board body 1. Two sides of the other end of the composite board body 1 are fixedly connected with second T-shaped columns 6. The second T-shaped columns 6 and the second T-shaped groove 4 are in a shape-fitting manner. A first T-shaped groove 5 is opened on the other side of one end of the composite board body 1. The first T-shaped groove 5 and the first T-shaped column 2 are in a shape-fitting manner.
[0025] First, align the first T-shaped column 2 with the first T-shaped groove 5 and the second T-shaped column 6 with the second T-shaped groove 4, and splice the two composite board bodies 1. Since the first T-shaped column 2 and the first T-shaped groove 5, and the second T-shaped column 6 and the second T-shaped groove 4 are in close contact, after splicing, the composite board bodies 1 are in close contact with each other, so that gaps can be avoided after splicing, and thus the thermal insulation and fireproof effects of the composite board can be prevented from being affected.
[0026] On both sides of one end of the composite board body 1 corresponding to the first T-shaped column 2, a telescopic groove 19 is opened. One end of the inner side of the telescopic groove 19 is fixedly connected with a spring 18. One end of the spring 18 is fixedly connected with a clamping column 3. On the inner side of the other end of the composite board body 1 corresponding to the second T-shaped column 6, a card slot 11 is opened. The card slot 11 and the clamping column 3 are in a shape-fitting manner.
[0027] After the splicing is completed, the clamping column 3 is clamped into the card slot 11 by the reset action of the spring 18, so that the two composite boards can be limited, and the situation of dislocation after splicing can be prevented.
[0028] In this embodiment, the composite board body 1 includes a reinforcement layer 7. A first reinforcing rib 12 and a second reinforcing rib 13 are respectively arranged inside the reinforcement layer 7. The first reinforcing rib 12 and the second reinforcing rib 13 are perpendicular to each other in space.
[0029] In the provided strengthening layer 7, there are a first reinforcing rib 12 and a second reinforcing rib 13. Therefore, the strength of the composite board body 1 can be improved, preventing breakage during use.
[0030] In this embodiment, the composite board body 1 further includes a fireproof and flame-retardant layer 8. Inside the fireproof and flame-retardant layer 8, there are respectively a silicate board layer 16 and an expanded perlite board layer 17. The silicate board layer 16 is a closed microporous network structure combined with a solid matrix. The electrostatic inorganic thermal insulation material contains a non-metallic mineral of magnesium, aluminum, and silicate - sepiolite as the base material, combined with a certain amount of auxiliary raw materials and fillers, and then a quantitative chemical additive is added. It is processed and manufactured using new processes and new technologies. The expanded perlite board layer 17 is a natural acidic vitreous volcanic lava non-metallic mineral product, including perlite, pinyolite, and obsidian. The three only differ in the crystal water content. Since its volume expands rapidly by 4 - 30 times under the high-temperature condition of 1000 - 1300 °C, they are collectively called expanded perlite. The silicate board layer 16 is arranged at the top of the expanded perlite board layer 17;
[0031] In the provided fireproof and flame-retardant layer 8, there are a silicate board layer 16 and an expanded perlite board layer 17. Therefore, it has excellent fireproof performance and high-temperature resistance performance.
[0032] In this embodiment, the composite board body 1 further includes a thermal insulation layer 9. Inside the thermal insulation layer 9, there are respectively a glass fiber layer 14 and a mineral wool layer 15. The glass fiber layer 14 is an inorganic non-metallic material with excellent performance, with a wide variety. Its advantages are good insulation, high heat resistance, good corrosion resistance, and high mechanical strength. The mineral wool layer 15 is a commonly used building thermal insulation material, mainly composed of mineral fibers and binders, and is processed through high-temperature melting and fibrillation. The glass fiber layer 14 is arranged at the top of the mineral wool layer 15;
[0033] In the provided thermal insulation layer 9, there are a glass fiber layer 14 and a mineral wool layer 15. Therefore, it has a good thermal insulation effect.
[0034] In this embodiment, the thermal insulation layer 9 is arranged at the bottom end of the fireproof and flame-retardant layer 8, and the fireproof and flame-retardant layer 8 is arranged at the bottom end of the strengthening layer 7.
[0035] It should be noted that the present utility model is a lightweight thermal insulation and fireproof composite board. During use, first align the first T-shaped column 2 with the first T-shaped groove 5 and the second T-shaped column 6 with the second T-shaped groove 4, so that the two composite board bodies 1 are spliced together. Since the first T-shaped column 2 and the first T-shaped groove 5, as well as the second T-shaped column 6 and the second T-shaped groove 4, are in close contact, after splicing, the composite board bodies 1 are in close contact with each other. Thus, gaps can be avoided after splicing, and the thermal insulation and fireproof effects of the composite board can be prevented from being affected;
[0036] And after the splicing is completed, the clamping post 3 is snapped into the clamping groove 11 under the reset action of the spring 18, so as to limit the two composite boards and prevent dislocation after splicing;
[0037] Moreover, the polyurethane coating 10 provided has good wear resistance and scratch resistance. In the reinforcing layer 7, there are the first reinforcing rib 12 and the second reinforcing rib 13, so the strength of the composite board body 1 can be improved to prevent breakage during use. In the fireproof and flame-retardant layer 8, there are the silicate board layer 16 and the expanded perlite board layer 17, so it has excellent fireproof performance and high-temperature resistance. And in the heat-insulating layer 9, there are the glass fiber layer 14 and the mineral wool layer 15, so it has a good heat-insulating effect.
