Description

Metal surface phenolic foam sandwich board for building
Technical Field
The invention relates to the technical field of building boards, in particular to a metal-faced phenolic foam sandwich board for buildings.
Background
The panels are flat rectangular building panels of standard dimensions, used in the construction industry as components of walls, ceilings or floors. But also to metal sheets formed by forging, rolling or casting. Divided into thin, medium, thick, extra-thick, generally standard sized flat rectangular building material panels. The sandwich board product consists of two layers of formed metal panels (or panels made of other materials) and a polymer heat-insulating inner core formed by directly foaming and curing the middle of the panels. The surface layer of the sandwich panel is made of common materials such as plywood, fiberboard, plastic board and metal sheet; the core material is made of light wood, rubber, cellulose acetate, plastics, resin-impregnated (or not) paper or cloth and metal honeycomb structure material. The surface layer material of the sandwich panel has more important influence on the physical performance and the environmental tolerance, and the core material determines the performances of the sandwich panel, such as heat preservation, sound insulation and the like.
The core material is a honeycomb-shaped cell structure material with a certain size. The kraft paper is usually roll-coated with sizing material on one side by a special sizing device, the distance between the offset positions of the paper coating parts on adjacent layers is half of the distance between two glue strips, and the width of the sizing line is the length of one side of a regular hexagon. The paper is overlapped and glued into a stack, then cut into a certain width by a guillotine, then heated to solidify the glue solution, and the two ends are pulled apart to form the hexagonal honeycomb structure. The skin material is selected according to the product requirements. The wall plate, the roof plate and the door leaf of the movable house are made of fiber boards; the cabinet furniture is usually made of plywood or veneer. When the surface material is glued with the core material, the core material is generally placed in a wood frame, the thickness of the wood frame is the same as that of the core material, and the upper surface and the lower surface of the core material are respectively covered with a gluing surface plate. The surface layer is made of wood, urea-formaldehyde glue or phenol glue. Then hot-pressed, typically at 0.2 to 0.3 MPa; the glued honeycomb plate is subjected to edge trimming, planing, edge punching and surface treatment to obtain a finished product. In the prior art, the conventional sandwich board needs to be improved in the aspects of heat preservation, sound insulation and the like, and the core material has poor environmental tolerance and gradually generates a pulverization phenomenon along with the prolonging of the service time.
