Embodiment: four layers of combined corrugated board of high strength
Shown in accompanying drawing 1, four layers of combined corrugated board of a kind of high strength, comprise facial tissue 1 and inner paper 2, between described facial tissue 1 and inner paper 2, are provided with corrugated structure layer; Described corrugated structure layer is comprised of the first corrugated layer 3, polyvinyl acetate rigid backbone 5 and the second corrugated layer 4, the form fit of the shape of described polyvinyl acetate rigid backbone 5 and described the first corrugated layer 3 and the second corrugated layer 4, described polyvinyl acetate rigid backbone 5 is folded between described the first corrugated layer 3 and the second corrugated layer 4.
Described facial tissue and inner paper all adopt 440g/m
2kraft paperboard.Described polyvinyl acetate rigid backbone 5 is the corrugated polyvinyl acetate ester film after solidifying, can adopt polyvinyl acetate glue adhesive coating layer or polyvinyl acetate emulsion coating to form after solidifying, polyvinyl acetate is wherein thermoplastic, after solidifying, has good rigidity.Described the first corrugated layer and the second corrugated layer all adopt 100g/m
2common corrugated paper.
Comparative example: Granted publication number is CN2923304Y, name is called the product that the disclosed technical scheme of Chinese utility model patent of < < mono-tile four-layer corrugated paper board > > makes.
Performance test: the mono-corrugated case standard of ASTM of the U.S. of take is example, that carries out paper joins material (note; DIN55468-1 carton standard and the American Standard of Germany are similar), in American Standard, the biggest quality of single corrugated case content can reach 55kg, and in this standard, the quality of cardboard face, inner paper is all 440g/m
2.Common single wall corrugated board is to be formed by 3 Paper or cardboard bondings, and corrugated structure layer adopts one deck corrugated paper.
After testing, the key index of the mono-tile four-layer combined corrugated board requirement with American Standard regulation considerably beyond German A mark.Comparing result sees the following form:
As seen from the above table, four layers of combined corrugated board of high strength that embodiment mono-makes, its physical index has surpassed the standard of USA and Europe; Side pressure strength is 1.48 times of German A targets, and exposing intensity is 1.33 times of German A targets, and pop strength is 1.35 times of German A targets, and all indexs have all surpassed Unite States Standard, has met the requirement of the heavy pound of single corrugation transporting paper.Meanwhile, meet the double-layer corrugated cardboard highest standard of stipulating in GB GB6544/T-2008, as can be seen here, suitable as long as mono-tile four-layer combined corrugated board is joined material, can replace double-layer corrugated cardboard completely.The adhesive of comparative example one is that conventional corn slurry only plays a cementation, and in order to reduce costs, paints a strip when coating adhesive, so its structure to corrugated paper cuts little ice, and its structural strength to whole corrugated board also cuts little ice.And the present invention to be the rigid backbone forming after utilizing poly vinyl acetate material to solidify support whole corrugated board, play structure-reinforced effect, therefore must be between two corrugated papers full version gluing.It is best-of-breed technology scheme that the present invention selects polyvinyl acetate glue adhesive coating layer.Polyvinyl acetate glue stick is comprised of main body composition polyvinyl acetate and other auxiliary agent, the fixation thereby the characteristic that makes polyvinyl acetate glue stick both have adhesive bonds, the effect also with poly vinyl acetate material itself is the rigid support effect plaing after it solidifies for thermoplastic possesses, when using, the present invention take other products that poly vinyl acetate material is stock for example during polyvinyl acetate emulsion, its cementation declines, but it also can meet requirement of the present invention, it is identical while solidifying rear rigid support effect plaing with use polyvinyl acetate glue stick.
Comparative example two, with a 200g/m
2the corrugated structure layer (100g/m of corrugated paper alternate embodiment
2corrugated paper+polyvinyl acetate rigid backbone+100g/m
2corrugated paper), in the situation that other material, processing conditions are identical, be processed into conventional single watt of triple wall board, test result shows: its side pressure strength is only 12393.4N/m, expose intensity 14.04J, pop strength 2200.0kPa, is starkly lower than four layers of combined corrugated board of high strength that embodiment mono-makes.This presentation of results 1+1>2, also illustrates that the polyvinyl acetate rigid backbone in corrugated structure layer plays the supporting role of rigid backbone.
The material polyvinyl acetate of polyvinyl acetate rigid backbone is a kind of thermoplastic resin, it can form a fixed structure with mechanical property after solidifying between two corrugated paper, so it can be used as the rigid backbone with supporting role and is used for supporting facial tissue and inner paper.Polyvinyl acetate rigid backbone have simultaneously good shock-resistant, intercept, moistureproof, water proofing property, so the corrugated board after compound has higher intensity, pop strength, the barrier property (gas permeability, water imbibition, oil absorption) of exposing.
