Vertical carbon fiber template and production method thereof

Abstract

The invention discloses a vertical carbon fiber template, comprising a carbon fiber composite skin made of carbon fiber cloth, spunlace non-woven fabric, random copolymerized polypropylene and a binder, and a core board formed by splicing and curing a plurality of wooden strips , two carbon fiber composite skins are pasted and connected to the large planes on both sides of the core board. The invention discloses a production method of a vertical carbon fiber template, which comprises the following steps: processing a core board; processing a carbon fiber composite skin; applying glue to the core board and the carbon fiber composite skin; covering the skin; cold pressing; hot pressing to obtain a finished product. The present invention uses construction waste templates as the main material to make the load-bearing main material, that is, the core board, and uses carbon fiber cloth, spunlace non-woven fabric, random copolymerized polypropylene and adhesive to jointly process it into a carbon fiber composite skin, and then the carbon fiber composite skin and The core board is processed into a vertical carbon fiber template through gluing, cold pressing, and hot pressing, which has the advantages of high reuse rate, cost saving, high density, high strength, wear resistance, and corrosion resistance.

Description

technical field [0001] The invention relates to a building formwork and a production method, in particular to a vertical carbon fiber formwork and a production method. Background technique [0002] The traditional building formwork is actually a kind of plywood. The difference is that the building formwork is a glued building formwork specially produced for pouring concrete in buildings, bridges, tunnels and other water conservancy projects. The production process is as follows: [0003] 1. Rotary cutting of logs: select high-quality eucalyptus logs, cut according to the budget of the veneer length required for production, and then go through the precision rotary cutting machine for rotary cutting and cutting; [0004] 2. Drying and finishing of the veneer: use the large drying yard of natural sunlight to dry naturally or by heating, and then arrange and pack; [0005] 3. Veneer gluing assembly: the veneer gluing assembly is precision and excellent four-roller gluing machin...

AI Technical Summary

Problems solved by technology

[0009] 1. Rotary cutting of logs needs to cut down a large number of trees, which has caused great damage to the ecological environment;

[0010] 2. Drying and finishing of veneer needs to invest a high cost to build a drying room and the operating cost is high;

[0011] 3. The veneer glue-coated billet adopts the horizontal and vertical staggered blanking method, the probability of misalignment and overlapping of the blanks is extremely high, the seam is large, the force is uneven, the strength is not high, the cost is extremely high, and it is extremely easy to delaminate;

[0012] 4. The surface of the formwork is easy to bond to the concrete, the concrete surface is uneven, the effect of clear water cannot be achieved, the number of turnovers is not high, and the corners of the formwork are delaminated and uneven after multiple turnovers, which affects the effect of another turnover

[0013] In order to solve the above problems, the applicant proposes a composite formwork in which veneer and core board are superimposed and glued together. This kind of formwork can be processed by waste wood, which can save a lot of wood, but there are still the following defects: longitudinally using multi-layer veneer superimposed and glued together by hot pressing , the wood around the edge of the board absorbs water and easily expands to cause delamination; in the process, the veneer is glued through the interlayer, which is prone to partial leakage of glue, resulting in delamination of the formed board veneer. The raw material for the veneer is a small amount of secondary skin or perforated board, repaired It cannot be perfected, and the overlap is easy to delaminate; the surface is heat-treated or covered with plastic, so that the surface of the formwork is not bonded when it is combined with the concrete, and it is easy to release the mold
