Method and device for improving interlayer bonding force of fiber reinforced building plate

Abstract

The invention discloses a method and a device for improving interlayer bonding force of a fiber reinforced building plate. The method comprises the following basic steps of a, adding slurry to a forming cylinder layer by layer by rotating to form a wet blank; b, when the wet blank reaches a certain thickness, enabling array needles on a plurality of arc-shaped acupuncture tiles above the forming cylinder to be in contact with and inserted into the wet blank gradually, and generating corresponding array holes; c, continuing receiving the slurry by the array holes so that the array holes are filled to form array rivets, and stripping the array rivets after the wet blank reaches the thickness; and d, pulling the arc-shaped acupuncture tiles to a starting side, and repeating the process aboveto realize continuous production. The device comprises the forming cylinder, the plurality of the arc-shaped acupuncture tiles, hinges, the array needles, an elliptical closed orbit, universal joints,hanging rods, a pulling motor, a control system, a lifting system and the like. The method and device disclosed by the invention are easily combined to a conventional copying method or slurry flowingmethod production line at present, and do not have limitation on components, thickness and the like of materials; and the performance of the obtained fiber reinforced building plate with improved interlayer bonding force is greatly improved.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a method for preparing a new type of fiber-reinforced building board. Background technique [0002] Fiber-reinforced building board is a building material made of cement or calcium silicate as the base material, mixed with various fibers as reinforcement materials, and various auxiliary materials. The building material is usually used for external wall protective panels, decorative panels, fireproof panels, thermal insulation panels, etc. of commercial or civil buildings. Existing fiber-reinforced building panels are generally produced on a large scale by the scissoring method or the flow-flow method, both of which require the use of forming cylinders to accumulate a certain thickness of wet billets layer by layer, and then carry out subsequent pressurization and steam curing of the wet billets And other special technical processing. Obviously, subsequent treatments such a...

Problems solved by technology

[0003] Aiming at the problems of poor interlayer bonding force and product anisotropy in fiber-reinforced building board products, a method and device for improving the interlayer bonding force of fiber-reinforced building board materials is proposed. In fact, it is easy to realize, and the product can greatly improve the bonding force in the thickness direction, realize the isotropy of product performance, make the aspect ratio close to 1, bring convenience to the plate construction, and greatly reduce the failure and damage of the product such as splitting and peeling , prolong product life
