Ultrathin bendable natural stone composite board and manufacture method thereof

Abstract

The invention belongs to the technical field of building materials, in particular to an ultrathin bendable natural stone composite board and a manufacture method thereof. The stone composite board comprises a wax layer, a stone layer, a rubber layer and a metal substrate layer in sequence from the outside to the inside, wherein the wax layer is an oil wax layer; the thickness of the stone layer is 1-1.5 mm; the minimum bending radius of the stone composite board is 500-600 mm; the rubber layer is made of polyurethane adhesives, the thickness of which is 0.15-0.2 mm and the elongation percentage of which is larger than 120 percent; the metal substrate layer is a No. 5052 alloy aluminium plate, the thickness of which is 0.8-1 mm. The manufacture method comprises the following steps of raw material pretreatment, gluing, compounding, cutting, side length and thickness determination, polishing, waxing, bending forming and the like. The invention improves the processing efficiency, reduces the wastes of stone, and can achieve the good effects of saving natural resources, reducing product cost and quality and facilitating manufacture and construction.

Description

Ultra-thin bendable natural stone composite board and manufacturing method thereof technical field The invention belongs to the technical field of building materials, and in particular relates to an ultra-thin bendable natural stone composite board and a manufacturing method thereof. The stone composite board is used for surface decoration of cylindrical surfaces or curved walls of buildings. Background technique It is often necessary to decorate various natural marble, granite and other stone slabs on the exterior and interior surfaces of buildings. Among them, for the stone slabs used for the columns and curved walls of buildings, as shown in Figure 1, the traditional method is to directly place stone panels on the stone. Curved stone slabs are cut out of the raw material according to the required radian, wherein the curved stone slab 11 and the stone raw material 22 are shown. This method produces a lot of leftovers, which is a waste of stone, and the minimum plate thic...

AI Technical Summary

Problems solved by technology

This method produces a lot of leftovers, which is a waste of stone, and the minimum plate thickness is generally required to be 35mm larger. If it is less than 35mm, the stone plate is prone to breakage during processing.
