Description
Technical field
The present invention relates to papery comb core and preparation method.
Background technology
Honeycomb is the masterpiece in the nature biotechnology evolutionary process, have best material weight space ratio, best mechanical structure, specific strength, specific stiffness, have good sound insulation, heat-insulating property, be widely used for partition wall, door, furniture, packing of space flight and aviation, car and boat, building materials etc.
Paper wasp nest goods are the cores that utilize paper material to be made, again in the both sides of core compound needed flush coat material, as color steel, plasterboard, plastic plate etc.Traditional paper honeycomb core material is that paper is carried out behind vertical gluing from level to level compound by certain aperture specification, is cut into the honeycomb core strip of required size according to cellular material thickness with paper cutter then, and drawn, the typing of heating become hexagonal honeycomb paper core again.Recently also developed the automation cellular device of horizontal gluing.No matter how high the automaticity of above-mentioned technology have, it still exists a kind of insoluble technical problem, promptly the product specification of Sheng Chaning is restricted: (1) when the height (thickness) of honeycomb paper core when 100mm is above, can occur can not draw away or unstable, density refractory is with control.(2) the papery grammes per square metre of the general refill of producing is when 80～180g/m2 is above, and the refill height is difficult to drawing and setting when 50mm is above.Therefore when the grammes per square metre of paper material is very limited, its compressive resistance also will be restricted.The thickness of the compressive resistance of papery honeycomb paper core and the material of paper, cellular densities, paper all has relation, in actual applications, also must give fire prevention, anticorrosion, sound insulation, adiabatic or the like performance according to industry requirement, the technology of prior art realizes that these function economical costs are than higher.
Summary of the invention
Technical problem to be solved by this invention provides a kind of improved papery comb core and its preparation method, and method is simple, and is practical, and the product specification range of choice of production is big, is easy to give every performance.
Engineering of the present invention papery comb core is characterized in that arranging the honeycomb complex that is bonded as one between outer wall successively in the same way by the papery pipe.
The method of producing this comb core is that the papery pipe is arranged bonding formation honeycomb complex between outer wall successively in the same way, and vertical papery tubular axis obtains the core of desired thickness to cutting.
The above-mentioned core of the equal specification of polylith is spliced into big specification by bonding, obtains the core of the honeycomb article of required size, on its two sides compound needed flush coat material promptly obtain the honeycomb composite article.
Both can be bonded as one between the papery pipe, also can be bonded as one with foamed adhesive by the mode of foaming by adhesive.Adhesive can be various inorganic or organic adhesives, as starch, phenolic resins, pollopas, epoxy resin, thermoplasticity thermosol, sodium metasilicate or the like.Foamed adhesive such as polyurethane foam, phenol formaldehyde foam etc., these expanded materials are filled in and not only play the effect that is adhesively fixed between the papery pipe but also the slit between the papery pipe is filled, improve the compressive resistance of honeycomb article, improve thermal insulation and soundproof effect, can also improve the fire resistance and the fire endurance of goods.Take which kind of bonding mode according to circumstances to select, when adopting general adhesive bonding, other some fillers also can be filled in the slit between the papery pipe, and the pressurization compound tense prevents distortion between the papery pipe.
According to waterproof, moistureproof needs, can be at the inwall of papery pipe or/and outer wall be compounded with aluminium foil or plastic membranous layer.
For core is improved more in the performance of aspects such as sound insulation, thermal insulation, intensity, can packing in the papery pipe.As in order to improve the heat-insulating property of comb core, can be in papery pipe (honeycomb hole) the lower foams plastic materials of thermal conductivity factor such as filled phenolic resin, polyurethane, rubber and plastic foam; In order to improve the sound insulation value of comb core, can fill sound absorption properties materials such as ore deposit rock wool, nonwoven in the papery pipe; In order to improve fire protecting performance, can fill aluminium silicate wool etc. in the papery pipe.
For satisfying the fire-retardant fireproof requirement of engineering with comb core, the papery pipe must carry out flame treatment, and a kind of feasible method is that the papery pipe is soaked in fire retardant, carries out air dry or heat drying after soaking into.Fire retardant can be the various products that reach flame retardant effect, and as aqua type fire retardant, resinae fire retardant, these all have known product to realize.Water base sex flame retardant such as inorganic ammonium, the aqueous solution of Phosphorus fire proofing, as ammonium sulfate, ammonium chloride, ammonium phosphate etc., organic APP etc. for another example.In order to improve the flame retardant effect of goods better, the adhesive between the papery pipe preferably also adopts flame retardant adhesive simultaneously.
The material of papery pipe of the present invention itself can be used common corrugated paper, high-strength stupefied paper, wood pulp paper, boxboard, brown paper etc. as required, or various paperys is compound, is wood pulp brown paper as internal layer and skin, and sandwich is a corrugated paper.In order to improve the intensity of papery pipe, can in the papery pipe, be added with reinforcing material such as nonwoven, glass fibre, carbon fiber, natural fiber, fabric etc.
Advantage of the present invention:
Production method is simple, practical, the specification of the comb core of making comprises that thickness, density range of choice are big, intensity, sound insulation, thermal insulation, fire prevention, performance such as fire-retardant are easy to realize and have very large-scale motor-driven selectivity, promptly if the adhesive of the material by adjusting the papery pipe, caliber, bonding usefulness, whether in flame treatment, the papery pipe whether packing material etc. make the comb core of required performance.As fire-retardant fireproof type, flame-proof damp-proof type, heat insulation-type, sound insulation type, enhancement mode, paper is compound, aluminium paper is compound or combination between them etc.The thickness of prepared comb core can be selected between 5～2000mm, and the honeycomb aperture can be selected between 8～200mm, and grammes per square metre can be at 150～50000g/m
2Between select, the comb core that concora crush compressive resistance Billy makes of conventional art improves 10～100 times.Fire-retardant fireproof: fire endurance can reach more than 1 hour.Sound insulation value can reach 30～80db, and heat-insulating property reaches 0.04w/m.k.
