Abstract
The invention discloses a hot melt glue joint pyramid lattice metal sandwich plate and a preparation method of the hot melt glue joint pyramid lattice metal sandwich plate. A pyramid lattice core body and a panel are in glue joint and combined by a hot melt glue film to obtain a super-light porous material. The preparation method for gluing the metal pyramid lattice sandwich plate by the hot melt glue film is implemented. According to the hot melt glue joint pyramid lattice metal sandwich plate, the manufacture cost is lowered; bulk production is achieved; residual stress in connection is reduced; the corrosion resistance, the fatigue property and the damping property of a connection position are improved; the performances of light weight, high specific strength and high specific rigidity are effectively played, and the hot melt glue joint pyramid lattice metal sandwich plate has a wide application prospect in the fields such as transportation and building decoration.
Description
Technical field
The present invention relates to a kind of pyramid dot matrix metal clip laminate and preparation method thereof, be specifically related to a kind of PUR and glued joint pyramid dot matrix metal clip laminate and preparation method thereof.
Background technology
The ultra light porous metal material is in the last few years along with material preparation and developing rapidly of Machining Technology and the one type of novel multifunction material that occurs.Its core body has high porosity; Its micro-structural can be divided into unordered and orderly two big types by regular degree; The former comprises closed-cell aluminum foam, and the latter comprises two-dimensional lattice material (like ripple struction) and three-dimensional truss structure (like pyramid structure, tetrahedral structure).
At present, common porous metal interlayer plate has truss structure sandwich plate and honeycomb aluminium interlayer plate.The wherein existing truss structure sandwich plate of being reported is made and is all adopted solder technology, complex process, and cost is high.At communications and transportation, building decoration etc. shear strength is required not too highly, more pay attention to lightweight, damping, the field is used and had bigger limitation cheaply.
Summary of the invention
The object of the present invention is to provide a kind of high specific strength, high specific stiffness excellent properties with truss structure, technology is simple simultaneously, cost is low, be prone to produce in batches PUR splicing pyramid dot matrix metal clip laminate that function expansibility is strong and preparation method thereof.
In order to achieve the above object, PUR of the present invention glueds joint the pyramid structure dot matrix metal sandwich plate that pyramid dot matrix metal clip laminate is made up of through the PUR splicing the core body of pyramid structure and panel.
Preparation method of the present invention may further comprise the steps:
1) at first adopts mold pressing or folding to form the pyramid core body that has node platform on the metal stretching net of punching diamond mesh or smooth mistake, pyramid core body and metal decking cleaning and removing are degreased and rusty stain;
2) then hot melt adhesive film is cut into ribbon, requires can cover fully at least each pyramid core body node platform, from bottom to up according to following metal decking, hot melt adhesive film, the pyramid core body, hot melt adhesive film, the order of last metal decking is fitted;
3) last; The pyramid dot matrix sandwich plate that posts is used clamp, place and treat under the 150-170 ℃ of corresponding melt temperature environment of hot melt adhesive film that hot melt adhesive film melts the back and takes out, normal temperature solidifies down; Clamper for disassembling promptly obtains PUR and glueds joint pyramid dot matrix metal clip laminate.
The material of described rhombus net is fine aluminium, aluminium alloy, stainless steel, titanium or titanium alloy.
Described stretching nets is aluminium expanded sheets or titanium board network.
Described metal decking is corrosion resistant plate, titanium plate or the titanium alloy sheet of aluminium sheet, aluminium alloy plate, minimal thickness.
Described hot melt adhesive film is a membrane-like, belongs to thermoplastic cement, selects polyester hot melting adhesive or iolon class for use.
Described step 1) also carries out mechanical grinding to the platform of pyramid core body with the joint face of the corresponding metal decking of platform of pyramid core body or oxidation processes is learned in phosphatization liquefaction, to strengthen glue-joint strength.
The metal pyramid dot matrix sandwich plate that the body invention adopts the PUR adhering method to prepare can be when keeping high specific strength, specific stiffness; Be more suitable for large-area batch process; And have low cost, improve heat-resisting, cold-resistant and impact resistance, have important application prospects in communications and transportation, building decoration field; And because its through-hole structure, function expansibility is strong.And use the excellent mechanical property of dot matrix metal and realize high specific strength, the light porous material of high specific stiffness.For example, porosity is 5.6% aluminium pyramid dot matrix sandwich plate, and compressive strength reaches 2.1MPa, and density is merely water density (1g/cm
3) 1/6.The present invention adopts selected PUR to have heat-resisting, cold-resistant and impact resistance, and it connects, and technology is simple, cost is low, be prone to produce in batches, and has through-hole structure, and compound with other functional materials of being more convenient for obtains the expansion of function.
