Embodiment 1
[0061] A heat-insulating and fire-proof color steel sandwich corner plate mixed with straw foam in this example includes a V-shaped plate, a long plate 4 and a heat-preserving and fire-proof sandwich material 9. The angle of the V-shaped plate is 90 degrees, and the left and right symmetrical structures have three parts. Types of V-shaped plates Ⅰ1, V-shaped plates Ⅱ2 and V-shaped plates Ⅲ3, their side widths are a, b and c respectively, and the relationship between the widths is The width of the long plate 4 is c; there are two V-shaped plates III3; the corner of the V-shaped plate II2 and one long side of the long plate 4 are fixedly connected to form a left-right symmetrical structure with a Y-shaped cross section, and the other long plate 4 The edge is connected with the corner of the V-shaped plate I1, so that the V-shaped plate I1 and the V-shaped plate II2 are assembled into a left-right symmetrical thermal insulation and fireproof color steel sandwich corner plate with...
Embodiment 2
[0074] In this embodiment, a heat-insulating and fire-proof color steel sandwich corner plate with mixed straw foaming, the basic structure is the same as that of embodiment 1, and the improvement is that the V-shaped plate adopts V-shaped color steel plate, such as figure 1 As shown, it also includes mortise joint devices arranged at the two tops of the heat-insulating and fire-proof color steel sandwich corner panels, the mortise joint devices are the groove plate 6 and the bump plate 5 arranged in cooperation; the heat-insulation and fire-proof color steel sandwich corner plate The two tops of the two tops are provided with opposite inner chamfers 7 that hold the mortise and tenon joint device.
[0075] The basic steps of the production process of a heat-insulating and fire-resistant color steel sandwich corner panel foamed by mixing straws in this embodiment are the same as those in Embodiment 1, and the improvement is that material A and material B are respectively combine...
Embodiment 3
[0090] The heat-insulating and fire-proof color steel sandwich corner panel with mixed straw foaming in this embodiment has the same basic structure as that in Embodiment 2, the difference is that the mortise joint device is replaced by a clamping device, and the clamping device is a male card and a female card. . Material A and B are combined basic phenolic resin and low-boiling alkane respectively; combined basic phenolic resin includes basic phenolic resin and emulsifier; low-boiling alkane is preferably normal pentane, isopentane, normal hexane, cyclopentane 1. One or more of petroleum ether, most preferably n-pentane-isopentane body, the present embodiment selects n-pentane-isopentane body;
[0091] The basic steps of the manufacturing process of a heat-insulating and fire-proof color steel sandwich corner panel foamed by mixing straws in this embodiment are the same as those in Embodiment 2, except that:
[0092] a. The mixing ratio of the test combination of basic phen...
