Problems solved by technology

[0004] In order to pursue light weight and heat preservation effect, most of the fillers between the existing color steel plates are foamed cement, which can not only ensure good strength, but also have good heat preservation effect, but in the preparation process, the cement sandwich is generally prepared first and then bonded. The method of color steel plate leads to limited bonding strength and prone to separation. Especially for cement sandwich with special shape, it is necessary to use color steel plate as a template to ensure accurate butt joint in the later stage, but it is still necessary to remove the color steel plate and apply glue. Bonding agent, not only the process is cumbersome but also the bonding strength is low

Abstract

The invention discloses an integrated preparation process of a foamed cement sandwich color steel plate, and belongs to the technical field of color steel plate preparation. The color steel plate is used as a template, a plurality of self-adhesive capsules are adsorbed on the surface of the color steel plate by utilizing a magnetic field, then a mold is matched for foaming to obtain a cement sandwich, and the self-adhesive capsules are reserved on the surface of the cement sandwich; in the later steam curing process, the self-adhesive capsules are heated and opened, meanwhile, air between the cement sandwich and the color steel plate is heated and expanded to jack up the color steel plate to form a gap, tentacles extend out under the action of the magnetic field to be close to the color steel plate subjected to corona treatment, and the tentacles are combined with pits in the surface of the color steel plate; and meanwhile, the extrusion releases a binder to fill the gap, then the high strength connection between the color steel plate and the cement sandwich is realized under heavy pressure after cooling, compared with the prior art, the foamed cement sandwich and the color steel plate can be integrally prepared, and the foamed cement sandwich and the color steel plate are high in bonding strength and not easy to separate.

Description

technical field [0001] The invention relates to the technical field of color steel plate preparation, and more specifically relates to an integrated preparation process of foam cement sandwich color steel plate. Background technique [0002] Color steel refers to color-coated steel plate. Color-coated steel plate is a steel plate with organic coating. It has good corrosion resistance, bright color, beautiful appearance, convenient processing and forming, and has the advantages of original strength of steel plate and low cost. Features. [0003] There are several types of traditional coatings. The most high-end coating is fluorocarbon coating, which can last for almost 20 years. It is generally distributed from steel mills to various places in the form of rolls. The color steel plate we often see refers to the processed plate with a thickness of about 50-100mm. It is composed of a filler in the middle and color steel plates on both sides. Among them, the thickness of the c...
