Abstract
A new paper honeycomb composite material, the panel core layer of the paper honeycomb structure is made up of grass fiber reinforced by glass fiber, the surface is made up of decorative paper or silk, satin and mounting paper, the bottom layer is bottom paper. During processing, the core layer and the bottom layer of the panel are dipped with modified urea-formaldehyde glue, the additive of the cellulose material is added into the bonding glue of the panel and the core, the surface of the core is grooved, and holes are formed on the frame edge. The composite material provided by the invention has low production cost and high performance, and can be widely used in military and civil products.
Description
The invention belongs to technical field of composite materials, proposed a kind of novel paper honeycomb structure composite.
In recent years, paper honeycomb composite material is in light weight with it, mechanical property is high and be subjected to the extensive attention of domestic technique circle, and is applied in some field.Utilize epoxy resin to make base-material as aircraft industry, make panel, do fuse, make some member of aircraft with nomex paper wasp nest with fiberglass or aluminium sheet etc.Paper wasp nest product is used for civilian also carrying out repeatedly attempts, but all eventually because of following former thereby not seen widespread use: (1), cost are too high; (2), technical problem such as unresolved fire-retardant, high temperature resistant, hypotoxicity, smog, protection against the tide; (3), fail fine solution and influence sandwich structure quality and cost owing to the technical problems such as bonding defect between surface layer and sandwich layer; (4), general panel is not with decoration, appearance plain, paint in addition or decoration veneer then increases cost.
The objective of the invention is to propose a kind of cheap, dependable performance, be suitable for civilian advanced composite material (ACM) product for solving above technical problem.
Basic ideas of the present invention are to adopt cheap raw material as far as possible, cheap glue is carried out modification, base-material is improved, and take certain technological measure to reach purpose of the present invention.
Concrete solution of the present invention is: (1) adopts cheap composite material face, with the bonding formation composite products of paper wasp nest sandwich.Composite material face is to add the glass fibre enhancing by grass fiber to make sandwich layer, adds overlay paper and bottom paper and constitutes; For overlay paper attractive in appearance can adopt facing paper, also can adopt silk, satin material to add and mount a layer paper formation, bottom is a bottom paper.Both did like this and can reduce material cost, and can make the panel can load again, also can play decoration function simultaneously; (2) adopt on the sandwich layer of panel and bottom paper that to soak modified urea-formaldehyde glue bonding, it is bonding that melamine glue is soaked in top layer and sandwich layer employing.Modifications such as modified urea-formaldehyde glue furfuryl alcohol, polyvinyl alcohol.Do like this, both can reduce cost, can guarantee the mechanical property of material again, also can make panel surface have anti-boiling hot, magnificent, hard characteristics; (3) additive of adding cellulosic material in the bonded adhesives of panel and paper wasp nest sandwich, to guarantee that panel and paper wasp nest sandwich cement, the fiber material feed additives that is added can be the fibrous material of selling on the market, also can be wood fiber materials such as saw foam, so but both guaranteed performances also can reduce cost greatly; (4), can guarantee that the sticking anchorage of panel and paper wasp nest sandwich is solid in paper honeycomb core and panel mutually bonding surface fluting, perforate exhaust on the edge of sealing around the paper honeycomb sandwich plate; (5) in paper wasp nest sandwich and modified urea-formaldehyde glue, also can add fire retardant, to improve high temperature resistant, the fire resistance of material.The fire retardant that is added can be a silica, also can be hydrated alumina etc.
Characteristics of the present invention are: (1) reduces the production cost owing to adopt cheap raw material greatly, makes it might extensive use in the product for civilian use.(2) owing to improvement to bonded adhesives, solved problems such as fire-retardant, high temperature resistant, hypotoxicity, protection against the tide preferably, made panel not only play decoration function, and can participate in stressed, and guaranteed panel and the bonding reliability of paper wasp nest sandwich, make it reach of the requirement of dual-use product to material.(3) surface decoration material can be selected for use arbitrarily with customer requirements, has improved the versatility of product.
The composite products that utilizes the present invention to make, can be made into the house partition wall, connect wall, cabin plate of door, go-cart, couchette bed board, furniture, convention table, steamer, train, automobile, floor etc., also can be made into stressed plate that unsteady house, artificial marble, band that band decorates decorate, house ceiling board etc., therefore, the present invention has a development prospect widely industrial.
