[0004] At present, the common method of producing building templates has the disadvantage that it cannot be produced continuously. Secondly, the adhesive layer of the template is formed by impregnating and curing reinforcing fibers and epoxy or polyester resin, so it cannot be recycled and reused, and the waste cannot be disposed of, which affects the environment.

Abstract
The invention discloses a recyclable composite material building template. The template disclosed by the invention comprises an upper surface layer, a lower surface layer and a core layer, wherein the thicknesses of the upper surface layer and the lower surface layer are 0.1-10mm respectively; and the thickness of the core layer is 3-15mm. The invention simultaneously discloses a manufacturing method of the recyclable composite material building template. The method disclosed by the invention comprises the following steps: firstly, preheating yarns led out from a yarn creel are preheated; laying and scattering the preheated yarns into a single yarn ribbon shape; unrolling a roll of thermoplastic resin film so as to be laid together with the material of the single yarn ribbon shape alternately in a laminating manner, simultaneously performing stentering, rolling, melting and immersing, and then performing cooling rolling and shaping to form a sheet; rolling and molding the sheet to prepare the needed upper surface layer and lower surface layer; and cutting the upper surface layer, the core layer and the lower surface layer according to the dimension requirements of the sheet, piling for lamination, and cooling, thus obtaining the composite sheet of the corresponding specification.
Description
technical field [0001] The invention relates to the field of building materials, in particular to a recyclable composite material building template and a manufacturing method thereof. Background technique [0002] At present, the building templates commonly used in the construction field are divided into four categories: one is wooden multi-layer plywood; one is steel formwork; one is bamboo sheet, and the other is plastic building formwork. [0003] The above-mentioned types of building formwork exist in the process of use, such as poor wear resistance, low rigidity / mass ratio, poor creep resistance, poor fatigue resistance, easy corrosion, difficult demoulding, short service life, non-recyclable, high cost of use, etc. Many disadvantages. [0004] The current common method of producing building formwork has the disadvantage that it cannot be produced continuously. Secondly, the bonding layer of the formwork is formed by impregnating and curing reinforcing fibers and epoxy...
