Abstract
The invention provides a preparation method of a lattice metal plastic foam composite material, truss lattice metal material and foam plastic are compounded to obtain multifunctional compound porous material. The invention has great significance for realizing the preparation of the truss lattice metal material and the foam plastic. The lattice foam composite metal laminated board can be applied to floors, ceilings, and carriages of an urban rail, a subway and an express train and has wide application prospect; the board can effectively reduce the structural weight, improve the heat-insulating and magnetic shield performance and save energy and so on. Particularly, in the machine manufacturing industry, the high strength and high rigidity and the excellent damping performance of the board can be given full play; In addition, the manufacturing cost of the board is even lower.
Description
Technical field
The present invention relates to a kind of preparation method of metal plastics foam compound material, be specifically related to a kind of preparation method of dot matrix metal plastics foam compound material.
Background technology
Metal laminate is in the last few years along with material preparation and developing rapidly of Machining Technology and a class novel multifunction material that occurs.Its core body has high porosity, and its micro-structural can be divided into unordered and orderly two big classes by regular degree, and the former comprises foamed materials (containing perforate and closed pore), and the latter mainly is lattice material (perforate).
At present, common laminate mostly is single structures such as foam, honeycomb or ripple, only possesses single function of planting, or single plant strong and other function reduction of function, the major advantage of making core as the closed pore rigid foam is to use it vibration isolation, heat insulation and sound insulation etc. are arranged, but shearing rigidity and intensity are all than shortcomings such as dot matrix core are low, and laterally shear strength and bearing capacity are lower, and this has seriously limited the application of foam core sandwich on main structure.Interior horizontal shear strength of purlin support type sandwich plate and bearing capacity are higher, but owing to do not contain viscoplasticity high damping material (as RPUF), energy-dissipating property is relatively poor.Even composite construction is perhaps arranged, also cost cost height adopts aluminium matter honeycomb to do core as Sullivan and Hitehouse because the difficulty of manufacturing technology is big, fills up polyurethane in the honeycomb, and the composite of this structure can be used for submarine.
Summary of the invention
The object of the present invention is to provide and a kind ofly realize that by compound mode functionality advantage separately is integrated, realize that multiple function is blended in the preparation method of dot matrix metal plastics foam compound material all over the body in conjunction with truss dot matrix metal and plastic foam advantage separately.
For achieving the above object, the technical solution used in the present invention is: at first the expanded metal lath with punching rhombus net or smooth mistake adopts mold pressing, folding to form the pyramid core body, adopt soldering or electric resistance welding that the pyramid core body is prepared into the pyramid dot matrix sandwich plate then, aluminium sheet with 0.5-2mm seals around the sandwich plate again, stay a casting gate, in baking oven, be heated to 40～60 ℃, guarantee cleaning in the die cavity, foreign matters such as water, greasy dirt can not be arranged; The poly methylene poly phenyl poly isocyanate of getting 80～100 parts sweet mellow wine polyethers, 10～20 parts tricresyl phosphate (2-chloroethyl) ester, 1.5～5 parts silicone oil, 1～5 part mass concentration then and be 25%～40% triethylene diamine, 20～30 parts chloro fluoroethane and 100-150 part stirs and makes macromolecule mixture; Macromolecule mixture is molded in the pyramid dot matrix sandwich plate foams, solidify the back and place 2～5h maturation process, remove aluminium sheet and promptly get dot matrix metal plastics foam compound material at 50～100 ℃.
Because the present invention uses the sound insulation of the mechanical property of truss dot matrix metal excellence and foam, the advantage separately of heat insulation, damping, realizes multi-functional coupling.Compare with honeycomb, the present invention has three-dimensional through-hole structure, and compound with foam of being more convenient for has lower cost.
