preparation example Construction

[0019] A method for preparing a laminated composite plate for vibration damping, comprising the following steps:

[0020] 1) Pre-treat the outer surface of the board II. The pretreatment includes pickling the outer surface of the board II first, then washing the board II in deionized water, and then drying the washed board II. use;

[0021] 2) Calculated in parts by mass, weigh 26~28 parts of Al and 72~74 parts of Zn and melt them in an intermediate frequency induction melting furnace. ~7min, to make each element homogeneous, refining and degassing, filtering and standing still to obtain the pouring solution;

[0022] 3) Apply a release agent on the inner surface of the cavity of the mold, place the plate II after step 1) in the cavity of the mold, the plate II divides the cavity of the mold into cavity I and cavity II, Cavity Ⅰ and cavity Ⅱ are arranged symmetrically with respect to plate Ⅱ, the width of cavity Ⅰ and cavity Ⅱ are the same as the thickness of the steel plate...

Embodiment 2

[0025] Since the fusion of aluminum and a certain proportion of zinc can significantly improve the fluidity, refine the grain structure of the casting and thus improve the mechanical properties, the smelted Zn-Al alloy is composed of the following components in parts by mass: Al 26-28 Parts, Zn 72~74 parts; Since the steel matrix is ​​required to provide stiffness and strength for this layered composite plate, but also to ensure elasticity as much as possible, the steel matrix in the layered composite material—plate II chooses 60Si2Mn steel .

[0026] A method for preparing a laminated composite plate for vibration damping, comprising the following steps:

[0027] 1) Pre-treat the outer surface of the board II. The pretreatment includes pickling the outer surface of the board II first, then washing the board II in deionized water, and then drying the washed board II. use;

[0028] 2) Calculated in parts by mass, weigh 26~28 parts of Al and 72~74 parts of Zn and melt them in ...

Abstract

The invention provides a lamellar composite plate for vibration damping and a preparation method thereof. The lamellar composite plate comprises a plate I, a plate II and a plate III, the plate I, theplate II and the plate III are arranged in sequence from top to bottom, the plate II is a steel plate, and raw materials for preparing the plate I and the plate III are all composed of the followingcomponents including, by mass, 26 to 28 parts of Al and 72 to 74 parts of Zn. The lamellar composite plate prepared through the method solves the problem that a traditional vibration damping plate issingle in performance; a liquid Zn-Al alloy and the steel plate subjected to surface treatment are subjected to liquid-solid-liquid compounding, and the Zn-Al / steel / Zn-Al lamellar composite plate withinterfacial metallurgical bonding is prepared, the lamellar composite plate has high rigidity, high strength and high elastoplasticity, the vibration damping effect can be effectively achieved, the conditions of structural damage and functional failures are reduced, and complementarity of the excellent properties of two metal materials is achieved; and the preparation method is used for carryingout liquid-solid-liquid compounding to prepare the Zn-Al / steel / Zn-Al lamellar composite plate, metallurgical bonding can be effectively promoted, operation is simple, energy saving is achieved, and the economic effect is obvious.

Description

technical field [0001] The invention relates to the field of processing and manufacturing layered composite materials, in particular to a layered composite plate for vibration reduction and a preparation method thereof. Background technique [0002] Due to its remarkable noise reduction and vibration reduction effects, the vibration damping plate is widely used in automobile manufacturing, construction industry and electrical appliances. Because steel has excellent characteristics such as high strength and high rigidity, but its vibration damping performance is weak; zinc-aluminum alloy has light weight, good vibration damping and wear resistance, but its strength and bearing capacity are insufficient under strong load conditions. In order to solve the problem of damage and failure of steel structures caused by vibration and working environment, it is necessary to introduce multi-component materials to improve the service life and damping performance of vibration damping pla...
