Composite liner of asbestos-free beater sheets and metal plate and manufacturing method and application thereof

Abstract

The invention discloses a composite liner of asbestos-free beater sheets and a metal plate and a manufacturing method thereof. The composite liner comprises two layers of the asbestos-free beater sheets, wherein the metal plate is composited between the asbestos-free beater sheets, and silica gel lines are silk-printed on the edges of the three layers. The manufacturing method comprises the following steps of 1, manufacturing the asbestos-free beater sheets and pretreating the metal core plate; 2, bonding and compounding the asbestos-free beater sheets and the pretreated metal core plate to prepare a composite plate; and 3, roll coating a layer of organic silicon coating on the surface of the composite board, stamping and forming, and finally silk-screen printing the silica gel line on theedge of the liner to obtain the composite liner. The composite liner of the asbestos-free beater sheets and the metal plate is applicable to sealing the joint surface of a vehicle power assembly. Thecomposite liner has excellent compression resilience performance, excellent corrosion resistance to lubricating oil, fuel oil and coolant as well as excellent sealing performance.

Description

technical field [0001] The invention belongs to the field of gearbox sealing, in particular to a composite liner of asbestos-free scissor plate and metal plate, a manufacturing method and application thereof. Background technique [0002] Transmission oil leakage is a common phenomenon in my country's construction machinery industry, especially the leakage of transmission gasket failure is particularly serious. Nowadays, the oil leakage of products has become an important indicator for the industry to evaluate the quality of gearboxes, and reducing the oil leakage of gearbox gasket failure has become an important basic task for the construction machinery industry. At present, the main sealing methods of the joint surface of the gearbox at home and abroad are mainly glue, paper pads and foam rubber composite pads, but the above sealing methods have more or less defects; the sealing method of glue has good sealing performance, Low cost but inconvenient to disassemble; the sea...
