Embodiment 1

[0061] In this example, a heat-insulating color-steel sandwich corner plate using straw foaming includes V-shaped plates, long plates 4 and heat-insulating sandwich materials 9. The angle of the V-shaped plates is 90 degrees, and the left and right symmetrical structures have three types. They are V-shaped plate Ⅰ1, V-shaped plate Ⅱ2 and V-shaped plate Ⅲ3 respectively, and their side widths are a, b and c respectively, and the relationship between the width and size is a=b+c / √2, b=√2×c; long plate The width of 4 is c; there are two V-shaped plates III3; the corner of the V-shaped plate II2 is fixedly connected with one long side of the long plate 4 to form a left-right symmetrical structure with a Y-shaped cross section, and the other long side of the long plate 4 and The corners of the V-shaped plate Ⅰ1 are connected, so that the V-shaped plate Ⅰ1 and the V-shaped plate Ⅱ2 are assembled into a V-shaped thermal insulation color steel sandwich corner plate with the long plate 4 ...

Embodiment 2

[0074] In this embodiment, a thermal insulation color steel sandwich corner plate using straw foaming, the basic structure is the same as that of embodiment 1, and the improvement is that the V-shaped plate is made of V-shaped color steel plate, such as figure 1 As shown, it also includes a tenon joint device arranged at the two top ends of the heat-insulation color steel sandwich corner plate, the tenon joint device is a groove plate 6 and a bump plate 5 arranged in cooperation; A top end is provided with an inner chamfer 7 which is opposite and clamps the mortise joint device.

[0075] In this embodiment, a production process of heat-insulating color-steel sandwich corner panels using straw foaming, the basic steps are the same as in Embodiment 1, and the improvement is that: material A and material B are respectively combined polyether and isocyanate. Steps to perform experiments and calculations before proceeding to Step A:

[0076] -2A. Test the mixing ratio of polyether...

Embodiment 3

[0090] The heat-insulating color steel sandwich corner panel using straw foaming in this embodiment has the same basic structure as that in Embodiment 2, except 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] In this embodiment, a production process of a heat-insulating color steel sandwich corner panel using straw foaming, the basic steps are the same as in Embodiment 2, except that:

[0092] -2A. Mixing ratio of test combination alkaline phenolic resin and n-pentane-isopentane body and expansion coefficient afte...

Abstract

The invention discloses a heat-preservation color steel sandwich corner plate adopting straw for foaming and a manufacturing technology thereof, and belongs to the technical field of building plates. The heat-preservation color steel sandwich corner plate comprises V-shaped plates, a long plate and a heat-preservation sandwich material. The V-shaped plates comprise two V-shaped plates III, one V-shaped plate I and one V-shaped plate II. The corner of the V-shaped plate II and one long edge of the long plate are fixedly connected to form a left-right symmetrical structure of the Y-shaped cross section. The other long edge of the long plate is connected with the corner of the V-shaped plate I. The V-shaped plate I and the V-shaped plate II are assembled to form the left-right symmetrical V-shaped heat-preservation color steel sandwich corner plate with the long plate as the center line. The two V-shaped plates III are distributed inside the left side and the right side of the heat-preservation color steel sandwich corner plate. The gap formed by the V-shaped plates and the long plate is filled with heat-preservation sandwich materials. The heat-preservation sandwich materials are straw-foamed heat-preservation materials. The heat-preservation color steel sandwich corner plate can be transported in a split mode and can be produced immediately, the purposes of reducing the transportation cost and tightly combining the inner layer and the outer layer are achieved, and straw from the village is sufficiently utilized.

Description

technical field [0001] The invention belongs to the technical field of building boards, and in particular relates to a heat-insulating color steel sandwich corner board using straw foaming and a manufacturing process thereof. Background technique [0002] my country is a large agricultural country with abundant crop straw resources, with an annual output of about 700 million tons of straw, ranking first in the world. In recent years, with the rapid development of my country's economy, the rural energy structure has undergone significant changes. The traditional demand for straw as living fuel has decreased year by year, resulting in the accumulation of most of the remaining straw. As a natural cellulose fiber, straw fiber has good biodegradability and can become an environmentally friendly product. Not only are these resources not being well utilized at present, but we can see the burning smoke in the fields every summer and autumn. These fumes bring inconvenience to peopl...
