Abstract

The invention provides a method for continuously producing ultrathin stone polyurethane composite plates. The method comprises the following steps of: splicing a plurality of ultrathin stones into a preprocessed plate, reserving a cutting gap of 5-10mm at a connection edge of adjacent ultrathin stones, removing dust and then sealing the gap between the adjacent ultrathin stone plates by utilizinga binder to form a continuous strip-shaped ultrathin stone; simultaneously conveying the strip-shaped ultrathin stone and a composite bottom liner into a constant-temperature foaming control chamber,spraying polyurethane between the strip-shaped ultrathin stone and the composite bottom liner to form a heat insulation layer, and carrying out foaming and shaping by adopting a conventional foaming process; and segmenting along the gaps among all ultrathin stone plates to obtain the finished product. The method and the device, provided by the invention, realize the aim of mechanical and continuous production, solve the batch processing difficulty of the ultrathin stone polyurethane composite plates, have the advantages of simple production process, easiness of operation, high production efficiency and good product quality and greatly satisfy the requirements of decoration markets.

Description

technical field [0001] The invention is an improvement to the existing ultra-thin stone polyurethane composite board production process, and further provides a continuous method for producing ultra-thin stone polyurethane composite board, and also discloses its production device, which belongs to the technical field of building material production. Background technique [0002] The structure of the ultra-thin stone polyurethane composite board involved in the present invention usually includes: a veneer, an insulation layer and an underlayment, the veneer is an ultra-thin stone with a thickness of 5-10mm, and the insulation layer is polyurethane with a thickness of 20-300mm and a density > 35kg. The backing is generally made of polymer mortar mesh cloth to form a protective layer, and the thickness is generally 1-3mm. The backing can also be made of aluminum platinum paper. At this time, the function is mainly to facilitate production or protect the composite board. The ge...
