specific Embodiment approach 2

[0019] A simple mold is used to directly cast manganese brass, a metal damping material, in the mesh holes and on the surface of the metal mesh composite plate to form a metal mesh plate manganese brass damping composite material. It increases the strength of manganese brass, and also prevents hot-rolled cladding, and the stress cracking problem of thick manganese brass in explosive welding cladding.

specific Embodiment approach 3

[0020] Lay a layer of barbed wire with a diameter of 1mm and a spacing of 2mm on the steel plate, and then lay a layer of glass cloth. After stacking three to six layers in total, put a layer of steel plate on it, and perform explosive compounding after compression. Carry out sealing welding. Due to the formation of many holes and fibers of different lengths between layers of glass cloth, the vibration and noise reduction effect is very good. The material is high temperature resistant, non-flammable, non-toxic and tasteless. It has high strength and is easy to connect with other structures. It is a promising vibration and noise reduction composite material.

Abstract

The invention relates to a metal screen damping composite material and the manufacture method. By explosive welding or spot welding, one or more than one layer of metal net and board is connected with the metal panel to form a metal net composite panel, viz. the metal screen. Various damp materials are added in the mesh and the surfaces of the metal screen. The damp materials can be added in the mesh and the surfaces of the metal screen by rubber vulcanization, plastic knife coating and solidification, direct plastic frothing, damp metal molding, explosive welding with a layer of glass cloth between the metal nets and other method. The manufacture method has the advantages that: the metal screen damp composite material keeps the damping performance and improves the intensity; the manufacture method solves the low combining intensity of the material and metal plate; prolongs the service lift of composite material and enlarges the application range.

Description

technical field [0001] The invention relates to a metal mesh damping composite material and its manufacturing method, in particular to a metal mesh composite board made of one or more layers of metal mesh and metal plates, and the metal mesh composite board The mesh and the surface are filled with rubber, plastic, foamed plastics, polyurethane elastomer, polyurethane foam elastomer, glass cloth, metal damping composite material with an integrated structure and a manufacturing method thereof. Background technique [0002] Some damping materials commonly used now, such as rubber, soft plastic, foam plastic, etc., have very low strength themselves, and the commonly used method when connecting with metal plates is to use adhesive bonding. The bonding strength is low, usually tens of megapascals, and it will fail in strong earthquakes and long-term vibrations. The service life is short, which is limited in application. In order to increase the strength of the damping material, ...
