Paper-plastic corrugated plate and fabricating method thereof

Abstract

The invention relates to elastic calcium-plastic corrugated paper which has an elastic buffer function and is formed by calcium-plastic paper, and a paper-plastic corrugated plate formed by the elastic calcium-plastic corrugated paper. The calcium-plastic paper is made into the elastic calcium-plastic corrugated paper with concave and convex surfaces by a concave die and a convex die, two sides of the elastic calcium-plastic paper with concave and convex surfaces are respectively provided with face paper and inside paper to form a single-layer paper-plastic corrugated plate; or more than one piece of calcium-plastic paper is respectively pressed into the concave and convex surface by the concave die and the convex die, and the concave and convex surfaces are formed into the multiplayer paper-plastic corrugated plate by the paper adhesion. The invention has the advantages that: firstly, the elasticity is good, the supporting strength is high, compared with the common paper-making corrugated plate, the weight is reduced by 30-40 percent, the production energy consumption is lowered by 1 / 3-1 / 2, the appearance volume is reduced by more than 10 percent, the supporting strength is improved by near 50 percent, more importantly, the paper-plastic corrugated plate can be recovered or can be automatically degraded under the natural environment; secondly, the protecting property is good, the elastic calcium-plastic corrugated paper has better elasticity and buffer property, can externally absorb the force produced by the outside force striking instantly, and can internally buffer the striking of objects to the paper-plastic corrugated plate instantly, therefore, the purpose of effectively and reliably protecting the objects is achieved.

Description

technical field [0001] The invention relates to a paper-plastic corrugated board made of elastic calcium-plastic corrugated paper with elastic buffer function, which belongs to the field of cardboard paper manufacturing. Background technique [0002] The inventor of this application has previously applied for CN1706634A, titled "paper-plastic composite cardboard and its production process", the paper-plastic composite cardboard includes face paper one and face paper two, and a plastic sheet is arranged between face paper one and face paper two material. Its production process is carried out according to the following steps: (1) unwinding and gluing of the plastic sheet, unwinding of the first face paper and the second face paper; (2) compounding of the first face paper, the plastic sheet, and the second face paper; (3) Drying, creasing; (4) Slitting, cross-cutting, stacking. Its shortcomings: First, although the plastic sheet has the functions of water-proof and moisture-p...

AI Technical Summary

Problems solved by technology

Its shortcomings: First, although the plastic sheet has the functions of water-proof and moisture-proof, when the sheet-like plastic sheet is used to make paper-plastic composite cardboard, it has neither elastic function nor cushioning function, so it can only be used as a The existing corrugated paper is used together, which not only increases the manufacturing cost, but also is not environmentally friendly, and its plastic sheets are difficult to decompose naturally in a natural state
