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 layered composite plate for vibration damping and a preparation method thereof. The layered composite plate includes plate I, plate II and plate III, plate I, plate II and plate III are arranged sequentially from top to bottom, and plate II It is a steel plate, and the raw materials for preparing plate I and plate III are composed of the following components by mass: 26-28 parts of Al and 72-74 parts of Zn. The layered composite plate prepared by the present invention changes the traditional damping plate For the problem of single performance, by liquid-solid-liquid composite of liquid Zn-Al alloy and surface-treated steel plate, an interfacial metallurgical bonded Zn-Al / steel / Zn-Al layered composite plate is obtained, which has high stiffness , high strength and high elastic-plasticity, can effectively play a damping role, reduce the situation of structural damage and functional failure, and realize the complementarity of the excellent properties of the two metal materials; use the preparation method provided by the invention to carry out liquid-solid-liquid Composite preparation of Zn-Al / steel / Zn-Al layered composite board can effectively promote metallurgical bonding, simple operation, energy saving, and obvious economic effect.

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...
