Embodiment 1

[0018] A preparation method of environmentally friendly zinc-aluminum damping alloy ZADAMP#1, which contains the following components by weight percentage: 20% Al, 0.5% Ti-RE master alloy, 0.5% Cu, 0.4% Mg, the balance is Zn. The preparation process includes the following steps:

[0019] (1) Dry and preheat the crucible at 300°C for 30min, and add Al metal block and covering agent first, because the melting point of pure Al is 660.32°C, and the melting temperature is usually 50~150°C higher than the melting point, so set the melting furnace temperature It should be 700~800℃ and keep it for a period of time.

[0020] (2) After the aluminum block is completely melted, add titanium and rare-earth master alloy particles. After the metal block is melted, add the copper block and the magnesium block. After melting, add the zinc block, add the covering agent after adding the zinc block, and adjust the melting furnace temperature to Keep it at 600~650℃ for a period of time. When the Zn i...

Embodiment 2

[0030] A preparation method of environmentally friendly zinc-aluminum damping alloy ZADAMP#2, which contains the following components by weight percentage: 15% Al, 0.3% Ti-RE master alloy, 0.25% Cu, 0.34% Mg, and the balance is Zn . The preparation processes (1) to (6) are as shown in the steps in Example 1.

[0031] Step (7): Heat the prepared zinc-aluminum damping alloy as follows: heat preservation at 330°C for 36 hours, quench it in an ice-water mixture between 0 and 10°C to cool to room temperature, and then age at room temperature 3 day. After the room temperature aging treatment, the quenched alloy is further placed in a heat treatment furnace, held at 330°C for 0.5 to 1 hour, and then discharged from the furnace for hot rolling at 330°C. The temperature fluctuation during the rolling process cannot exceed 10°C, and then returned to the furnace Keep the temperature at 330°C for 5-10 minutes, and then roll it further, the alloy reduction rate is 25%. After that, the allo...

Embodiment 3

[0033] A preparation method of environmentally friendly zinc-aluminum damping alloy ZADAMP#3, which contains the following components by weight percentage: 27.5% Al, 0.01% Ti, 0.2% rare earth, and the balance is Zn. The preparation processes (1) to (6) are as shown in the steps in Example 1.

[0034] Step (7): Heat the prepared zinc-aluminum damping alloy as follows: heat preservation at 350°C for 48 hours, quench it in an ice-water mixture between 0 and 10°C to cool to room temperature, and then age at room temperature 3 day. After the room temperature aging treatment, the quenched alloy is further placed in a heat treatment furnace, held at 350°C for 0.5 to 1 hour, and then discharged from the furnace for hot rolling at 350°C. The temperature fluctuation during the rolling process should not exceed 10°C, and then returned to the furnace. Keep it at 350°C for 5-10 minutes, and then roll it further. The reduction rate of the alloy is 70%. After that, the alloy plate is placed i...

Abstract

The invention discloses an environmental-friendly zinc-aluminum damping alloy and a preparation method of the environmental-friendly zinc-aluminum damping alloy. The alloy is made of, by weight percentage, 15%-27% of Al, 0.01%-0.1% of Ti, 0.1%-0.2% of rare earth, 0.02%-0.62% of Cu, 0.01%-0.5% of Mg and the balance Zn, and the sum of the weight percentages is 100%. Through the alloying and heat treatment processes, the microstructure of the alloy is obviously refined and uniformized, and the mechanical property of an existing zinc-aluminum alloy is improved. Compared with the existing zinc-aluminum damping alloy, according to the environmental-friendly zinc-aluminum damping alloy, alloy compositions do not contain silicon and lead, machining and cutting are easy, the alloy is not broken easily, environmental protection and zero pollution are achieved, and the alloy has good damping performance. The novel zinc-aluminum damping alloy can be used as a shock absorbing material and is widely used in the fields of building materials, electronics, general machines and the like.

Description

Technical field [0001] The invention belongs to the field of alloys, and specifically relates to an environment-friendly zinc-aluminum damping alloy and a preparation method thereof. Background technique [0002] With the rapid development of industry nowadays, vibration and noise seriously affect the stability and reliability of mechanical equipment operation. At the same time, the requirements for the safety of building structures against earthquakes and disasters are getting higher and higher, and seismic and noise reduction has become a key engineering problem that urgently needs to be solved in many fields. The core of solving the problem of vibration and noise reduction is to find high-performance damping materials. Metal damper is an energy-consuming device with simple structure and low cost, which is widely used. The metal dampers used by people now mainly include mild steel dampers, lead dampers, and shape memory alloy dampers. Mild steel dampers include out-of-plane ...
