Embodiment 1

[0025] 155g of aluminum block and 419g of zinc block are prepared by conventional casting method to produce Zn-27%Al foamed zinc-aluminum alloy; the rosin is heated and melted at 150°C, kept for 15 minutes, and the foamed zinc-aluminum alloy prepared above is soaked into the liquid After heating in rosin for 10 minutes, turn off the power to cool down, and when the temperature drops to 100°C, take it out and cool it in air to obtain a polymer / foam zinc-aluminum alloy composite material.

Embodiment 2

[0027] 96.5g aluminum block and 342g zinc block were prepared by powder metallurgy to produce Zn-22%Al foamed zinc-aluminum alloy; the paraffin was heated and melted at 200°C, kept for 30 minutes, and the foamed zinc-aluminum alloy was soaked in liquid paraffin. Heat for 3 minutes, then turn off the power to cool down, and when the temperature drops to 40°C, take it out and cool it in air to obtain a polymer / foam zinc-aluminum alloy composite material.

Embodiment 3

[0029] Put 155g of aluminum block into the crucible, heat to melt in the resistance furnace, then add 419g of zinc block into the crucible to prepare Zn-27%Al alloy solution, keep the Zn-27%Al alloy melt temperature at 550°C; Melt the salt, remove crystal water, crush and sieve it into 21g of salt with a diameter of 0.1mm, put it into the mold and compact it, and preheat and keep the mold with salt at 550°C, and connect the mold to Negative pressure infiltration device, and then insert the mold into the alloy melt to make it infiltrate under negative pressure for 40 seconds. After the alloy is solidified, remove the salt filler and obtain a mass of 39g, a pore diameter of 0.1mm, and a porosity of more than 80%. Φ20mm×65mm through-hole foamed Zn-27%Al alloy; put the rosin in a crucible and heat it to 200°C on an electric furnace, and after holding it for 20 minutes, soak the foamed Zn-27%Al alloy prepared above into the liquid rosin , and then heated for 5 minutes, turned off t...

Abstract

The invention discloses a manufacturing method for polymer / foam allumen composite material. It includes the following steps: making foam allumen, and infiltrating high molecular material into the holes of allumen. The invention sharply improves the damping performance comparing with single identity allumen orsingle foam allumen.

Description

technical field [0001] The invention belongs to the technical field of metal-based composite materials, and in particular relates to a preparation method of a composite material formed of foamed zinc-aluminum alloy and polymer materials. Background technique [0002] Vibration and noise not only affect the accuracy and life of the machine, but also deteriorate the working environment, affect people's health, make people tired, tinnitus, and even incapacity in severe cases. The use of high damping materials is one of the most effective means to solve vibration and noise problems. Polymer viscoelastic materials have excellent damping properties, but poor strength; foam metal materials not only have good strength, but also have good damping properties. If the two are combined together to form a composite material, the two materials can be fully utilized. With their respective advantages, a composite damping material can be developed to better solve vibration and noise problems...
