preparation example Construction

[0017] The invention provides a method for preparing a composite color steel tile with high fire resistance, which comprises the following steps:

[0018] (1) Preliminary treatment of the color steel tile body, that is, cold-rolled steel plate or galvanized steel plate, including removing oil, dust and debris;

[0019] (2) Preparation of thermal conductive layer paint: Weigh the raw materials according to the formula, disperse graphene oxide powder and alumina powder into the high temperature resistant adhesive, stir evenly and spray on the color steel tile body of step (1), and then dry it. After drying, a heat-conducting layer is formed, and the two sides of the color steel tile body are respectively processed to obtain a semi-finished product A with heat-conducting layers on both sides;

[0020] Open through holes on the semi-finished product A, the diameter of the through holes is 0.8-1.5cm; the spacing of the through holes is 2-5cm; and then use a forming machine to form corruga...

Abstract

The invention belongs to the technical field of processing of color steel tiles and particularly relates to a preparation method of a high-fireproof composite color steel tile. The method includes (1)pretreating a color steel tile body; (2) preparing a heat conductive layer coating, and coating the color steel tile body with the coating to obtain a semi-product A, and forming through holes in andshaping corrugated structures on the semi-product A; (3) forming fireproof layers to prepare a semi-product B; (4) forming a surface paint layer to produce the composite color steel tile. By arranging the heat conductive layers on two sides of the color steel tile and the fireproof layers on outer sides of the heat conductive layers, when fire hazard breaks out, fireproof layers have great fireproof and heat-insulation effect during use. In addition, the heat transmitted to the color steel tile body can be dissipated via the heat conductive layers in order to prevent deformation due to concentrated heat.

Description

Technical field [0001] The invention belongs to the technical field of color steel tile processing, and specifically relates to a method for preparing 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 uses color coated steel plate and is rolled 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, which is made by applying organic film such as roll coating or compounding PVC on the surface of the steel sheet after chemical treatment and baking and curing Into steel products. Color coated steel plate 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 roofing, wall and interior and exterior wall decoration of industrial and civil buil...
