Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The fire-proof and heat-retaining color steel sandwich panel of the present invention comprises a face plate and a bottom plate made of color steel and a core layer between the bottom plate and the face plate, and the core layer includes a mixture of vitrified microspheres and inorganic gel materials.

[0024] Preferably, the inorganic gel material is water glass. During specific implementation, the core layer is made of vitrified microspheres, water glass, sodium fluorosilicate and water-repellent agent, wherein the mass ratio of vitrified microspheres and water glass is 50-120:20-80, and sodium fluorosilicate is 1%-10% of the water glass mass, and the water repellent is 0.5%-5% of the water glass mass. The preferred implementation ratio is: the mass ratio of vitrified microspheres to water glass is 100:30-50, sodium fluorosilicate i...

Abstract

The invention discloses a fireproof heat-preservation colored steel sandwich board and a preparation method thereof. The fireproof heat-preservation colored steel sandwich board comprises a surface plate, a bottom plate and a sandwich layer located between the surface plate and the bottom plate, wherein the surface plate and the bottom plate are composed of colored steel. The sandwich layer is a mixture composed of glass beads and inorganic gel materials. During preparation, the rectangular colored steel is placed on a work table top to serve as the bottom plate; then surrounding plates are fixedly arranged on the periphery of the bottom plate, so that a containing cavity structure is formed by the surrounding plates and the bottom plate together; sandwich layer materials prepared in advance are poured into the containing cavity, and a pressing plate is used for flattening and compacting the surface of the sandwich layer materials; and the surface plate is laid on the surface of the sandwich layer materials, the periphery of the surface plate is fixed to the surrounding plates through connectors, and finally curing and drying are conducted, so that the fireproof heat-preservation colored steel sandwich board is obtained. The colored steel sandwich board has excellent fireproof and heat preservation properties at the same time and is low in weight. The preparation method of the fireproof heat-preservation colored steel sandwich board is simple and efficient.

Description

technical field [0001] The invention relates to a color steel sandwich panel, and also relates to a preparation method of the fireproof and thermal insulation color steel sandwich panel, which belongs to the technical field of building materials. Background technique [0002] Color steel plate is color coated steel plate, which is a kind of steel plate with organic coating. It is named after the iron sheet with a layer of color coating on the outer layer. Warehouses, shops, kiosks and temporary housing on construction sites. The core materials of color steel plates mainly include polystyrene, polyurethane and rock wool. Among them, although polystyrene and polyurethane are light in weight, they are combustible and combustible materials. The fire test conducted by the fire department in the color steel plate house showed that 2 minutes after the internal household items caught fire in the non-steel structure polystyrene color steel plate house, a large amount of black smoke...
