preparation example Construction

[0044] The preparation method of the high refractory composite color steel tile of the present invention comprises the following steps:

[0045] (1) Preliminary treatment of the color steel tile body, that is, cold-rolled steel plate or galvanized steel plate, including removal of oil, dust and sundries;

[0046] (2) Preparation of heat-conducting layer coating: Weigh the raw materials according to the formula, disperse graphene oxide powder and alumina powder into the high-temperature-resistant adhesive, stir them evenly, and spray them on the color steel tile body in step (1), after baking After drying, a heat conduction layer is formed, and the two sides of the color steel tile body are respectively treated to obtain a semi-finished product A with heat conduction layers on both sides;

[0047] Open through holes on the above-mentioned semi-finished product A, the diameter of the through holes is 0.8-1.5 cm; the distance between the through-holes is 2-5 cm; then use a moldin...

Embodiment 1

[0054] A composite color steel tile, comprising a color steel tile body and heat conduction layers arranged on both sides of the color steel tile body, a refractory layer is arranged on the outside of the heat conduction layer, and a topcoat layer is arranged on the outside of the refractory layer;

[0055] The refractory layer is prepared from the following raw materials in parts by weight: 55 parts of clay, 4 parts of corundum powder, 3 parts of alumina powder, 15 parts of silica powder, 20 parts of yellow dextrin, and 110 parts of water; the thickness of the refractory layer is 5mm ;

Abstract

The invention belongs to the technical field of color steel tiles, and particularly relates to a composite color steel tile with high fire resistance, which comprises a color steel tile body and heatconducting layers arranged on two sides of the color steel tile body, wherein the outer sides of the heat conducting layer are both provided with a refractory layer, and a surface paint layer is arranged on the outer side of the refractory layer; the refractory layer is prepared, by weight, from the following raw materials: 42-75 parts of clay, 2-7 parts of corundum powder, 1-5 parts of alumina powder, 8-20 parts of silica powder, 10-35 parts of yellow dextrin and 95-130 parts of water; according to the invention, the heat conducting layers are arranged on two sides of the color steel tile body, the refractory layer is arranged on the outer side of each heat conducting layer, when in use, if a fire occurs, the refractory layer has better refractory and heat insulation effects, and, the heat conducting layer can dissipate the heat transferred to the color steel tile body and the deformation problem caused by over centralized heating is avoided.

Description

technical field [0001] The invention belongs to the technical field of color steel tiles, in particular to a composite color steel tile with high fire resistance. Background technique [0002] Color steel tile, also known as color profiled tile, is a profiled plate that is made of color-coated steel plates that are rolled and cold-bent into various wave shapes. The color-coated steel sheet used to manufacture color steel tiles is usually cold-rolled steel sheet or galvanized steel sheet. finished steel products. Color-coated steel sheet not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials. It is suitable for the roof, wall and interior and exterior wall decoration of industrial and civil buildings, warehouses, special buildings, and large-span steel structure houses. Long, maintenance-free and other characteristics, has been widely promoted and applied. [0...
