There are many kinds of corrugated tiles, such as fiberglass corrugated tiles, which have high strength, but are not flame-retardant. Once discarded, they cannot be degraded and cannot be used repeatedly. For example, metal corrugated tiles have high strength, but poor texture and strong thermal conductivity. , if it is used for the roof, it is not conducive to heat insulation, the use effect is poor, and the specific weight is high, the cost is high, and once deformed, it is not easy to restore

Abstract
The invention provides a rigid polyvinyl chloride pantile and a preparation method thereof, and relates to a composite material, a structural material and the preparation method thereof. The rigid polyvinyl chloride pantile is composed of an aging-resistant layer, a structural layer and a bottom layer, wherein, the structural layer positioned between the aging-resistant layer and the bottom layer is formed by extruding polrvinyl chloride, calciumpowder, chlorinated polyethylene, calciumstearate, acrylic resin, polyethylenewax and the like; the aging-resistant layer is formed by extruding polrvinyl chloride, calciumpowder, chlorinated polyethylene, calcium stearate, DCP Dicapryl Phthalate, antioxygen, polyethylenewax and the like; and the bottom layer is formed by extruding polrvinyl chloride, calcium powder, chlorinated polyethylene, calcium stearate, DCP Dicapryl Phthalate, titaniumpigment, polyethylenewax and the like. The aging-resistant layer, the structural layer and the bottom layer are laminated and coextruded through a rectangular port die to obtain a rectangular flat-sheet material, and then the flat-sheet material is cooled for shaping by a waveform shaping die to form the rigid polyvinyl chloride pantile. The rigid polyvinyl chloride pantile of the invention has reasonable design, simple structure, convenient production and manufacturing. Compared with other pantiles, the pantile of the invention not only has light weight and good thermal insulation performance, but also can be flame-resistant, reused and made from waste plastics, thereby being economical, environmentally-friendly, and suitable for manufacturing head cover plates for plants, warehouses, car sheds, makeshift houses, re-roofing projects and the like, walls of construction sites and the like.
Description
technical field [0001] The invention relates to a rigid polyvinyl chloride corrugated tile and a preparation method thereof, which relate to a composite material, a structural material and a preparation method thereof, and are suitable for manufacturing workshops, warehouses, carports, simple housing, flat-to-slope projects, etc. Roof panels and walls of construction sites, etc. Background technique [0002] The rapid economic development has led to a large number of construction projects. On the one hand, many places have newly built factories, warehouses, carports and other facilities. On the other hand, in order to beautify the environment and improve living conditions, many places have converted some old buildings into flat roofs For the transformation of the slope top (flat to slope), there are still a large number of construction sites that need to be closed for construction, so as not to reduce the impact on the environment and traffic. All the above projects can use ...
