Composite metal tile and its making process

Abstract

The invention relates to a complex metal tile, comprising colored metal or nonmetal plate, characterized in that paint primer layer, which is heated to melt for connecting with polyethylene foaming plate, is set at the back of colored metal or nonmetal plate. The manufacturing method is that composite forming of prefabirated metal or nonmetal plate heated with the paint primer at the back and polyethylene foaming plate, sheet forming, cutting and finishing. The invention is provided with the benefit effect that because the technology method that coating the paint primer at the back of metal and nonmetal plate in advance, generating the substance with bonding component by heating and melting and refreezing, is applied, the dividing limitation of steel plate and heat insulation material by commonly using the layer pressed way of glue bonding can be conquered. It can eliminate the problem existing in metal tile such as noise, heat insulation, heat preservation and so on. Polyethylene foaming plate is pressed at the back of metal tile so as to absorb and decrease the metal vibration at the maximum extent, solve the noise problem effectively, solve problems such as heat insulation, heat preservation and so on, and resist firing.

Description

technical field [0001] The invention belongs to building materials, in particular to a composite metal tile and a manufacturing method thereof. Background technique [0002] There are many kinds of tiles used in building construction, and there are usually two manufacturing methods besides traditional mud tiles: one is to punch metal sheets and injection-molded VC series materials, and then make mud tile-like metal tiles; the other It is a production method of roll forming color steel, and the production process requires adhesive bonding. After 3 years, the metal plate and the thermal insulation material are separated, the interior is easy to corrode, and the service life is short. The metal tile has been widely used in the construction of roof capping of various buildings. It has the characteristics of environmental friendliness, beautiful appearance and strong durability. Its application range has gradually expanded from the original ordinary residence to the roof of vill...

AI Technical Summary

Problems solved by technology

However, metal tiles have disadvantages such as poor thermal insulation performance and dew condensation. At the same time, during construction, it is necessary to lay various insulation materials on the bottom of the roofing material, and then use metal tiles to seal the roof. Therefore, there are complex construction, high engineering costs, and economical gender issues
