Abstract
The utility model relates to the field of composite sandwich plates, and discloses an assembled BFRP and rock wool composite sandwich plate. The assembled BFRP and rock wool composite sandwich board is mainly formed by bonding and pressing a core layer and a surface layer; the sandwich layer of the composite sandwich board consists of honeycomb-shaped BFRP hollow boards and BFRP solid boards, the surface layer of the composite sandwich board adopts refractory rock wool boards, and the side surface of the sandwich board is provided with BFRP tenons and mortises for assembly. The composite assembled sandwich panel has good sound absorption, corrosion resistance and fire resistance, and the sandwich panel has light weight and high strength, so the composite sandwich panel can be used for floor slabs and wall plates in building construction and floors for building decoration.
Description
Technical Field
The utility model belongs to the field of composite sandwich plates, and particularly relates to an assembled BFRP and rock wool composite sandwich plate.
Background
The board can be seen everywhere in daily life, such as floor, wall board, roof board, etc. for building. In recent years, national security has become more and more important for buildings, and thus, high strength, durability and fire resistance are required for the slabs and wall panels for building stress. The rock wool product is made of basalt as main material and through solidification and shaping, and has excellent heat insulating, fireproof, sound absorbing, noise reducing and earthquake resisting performance, but not high strength. The basalt fiber reinforced composite material (BFRP) is prepared by a specific process of basalt fiber and a resin matrix, wherein the basalt fiber is formed by melting basalt at high temperature and drawing the basalt fiber at high speed by a wire drawing machine, and the basalt fiber reinforced composite material (BFRP) is an environment-friendly material which is light, high in strength, good in sound absorption and durability, but the strength of the BFRP can be reduced at high temperature. Therefore, the fireproof rock wool board and the BFRP board are organically combined to prepare the sandwich board which has good sound absorption, corrosion resistance, fire resistance, light weight and high strength.
Disclosure of Invention
The utility model aims to design a sandwich panel which is light in weight, high in strength, heat-insulating, corrosion-resistant and good in sound absorption performance.
The utility model is formed by bonding and pressing a core layer and a surface layer.
The sandwich layer uses a honeycomb-shaped BFRP hollow plate as a middle layer, and a BFRP solid plate as a surface layer of the sandwich plate.
The surface layer adopts an upper refractory rock wool board and a lower refractory rock wool board.
The side of the sandwich board is provided with a BFRP tenon and a mortise.
The adhesives between the upper refractory rock wool plate and the upper BFRP solid plate, between the upper BFRP solid plate and the honeycomb-shaped BFRP hollow plate, between the honeycomb-shaped BFRP hollow plate and the lower BFRP solid plate, and between the lower BFRP solid plate and the lower refractory rock wool plate are all selected from high-temperature-resistant epoxy resin.
Has the advantages that:
1. the utility model has little pollution to the environment in the production process.
2. The utility model has the characteristics of light weight, high strength, heat preservation, heat insulation, corrosion resistance, good sound absorption performance and the like.

Detailed Description
The present invention will be described in detail with reference to the following detailed description and accompanying drawings.
As shown in fig. 1, a BFRP, rock wool composite sandwich panel mainly includes: the composite plate comprises an upper refractory rock wool plate, an upper BFRP solid plate, a BFRP tongue, a honeycomb BFRP hollow plate, a mortise, a lower BFRP solid plate and a lower refractory rock wool plate. The BFRP and rock wool composite sandwich board is formed by bonding and pressing a core layer and a surface layer; the sandwich layer takes a honeycomb-shaped BFRP hollow plate as a middle layer of the sandwich layer, and an upper BFRP solid plate and a lower BFRP solid plate are taken as surface layers of the sandwich layer of the sandwich plate; the surface layer adopts an upper refractory rock wool board and a lower refractory rock wool board.
In the embodiment, the upper and lower surfaces of the upper and lower prefabricated BFRP solid plates 2 and 6 are subjected to sand blasting, a curing agent and high-temperature-resistant epoxy resin are mixed according to a certain proportion and then uniformly coated on the upper and lower surfaces of the upper and lower BFRP solid plates 2 and 6, the upper and lower BFRP solid plates 2 and 6 are respectively pressed on the upper and lower surfaces of the prefabricated honeycomb-shaped BFRP hollow plate 4 to form a sandwich plate core layer with BFRP tongue tabs 3 and mortise slots 5, finally the upper refractory rock wool plate 1 is pressed on the upper BFRP solid plate 2, and the lower refractory rock wool plate is pressed on the lower BFRP solid plate 6, so that the sandwich plate which has good sound absorption, corrosion resistance and fire resistance, light weight, high strength and assembly is finally produced.
Terms with orientation, such as upper refractory rock wool panel, upper BFRP solid panel, lower refractory rock wool panel, left and right sides, etc., used in the present invention are for the purpose of more clearly describing the structural components of the present invention, and the same embodiments or examples are not necessarily intended for schematic representations of the above terms.
