Embodiment Construction

[0009] In reality, the bonding process of the nitrile rubber adhesive used for bonding between metal and nitrile rubber stipulates that the pressure when curing at room temperature is 0.01 to 0.2 MPa, that is, 0.1 to 2 ㎏ / cm2. This room temperature bonding pressure is extremely difficult for the bonding and manufacturing of metal and nitrile rubber bonding assemblies, so reducing the molding pressure for curing at room temperature is of great significance. The inventor has often verified through long-term experiments and concluded the invention. The principles and features of the invention will be described below with examples.

Abstract

A room-temperature low-pressure bonding technology for nitrile butadiene rubber and metal comprises the steps as follows: (1) surface treatment of a metal part; (2) surface treatment of a nitrile butadiene rubber plate or profile; (3) preparation of an XY502 nitrile butadiene rubber adhesive; (4) adhesive coating: the prepared XY502 nitrile butadiene rubber adhesive is uniformly brushed on a bonding part of the cleaned metal part and a bonding part of the polished nitrile butadiene rubber plate or profile with a soft brush; (5) bonding and curing: the metal part and the nitrile butadiene rubber plate or profile coated with the XY502 nitrile butadiene rubber adhesive are attached together. By means of the room-temperature low-pressure bonding technology for the nitrile butadiene rubber andthe metal, the technical problem of ultrahigh bonding molding curing pressure of a metal and nitrile butadiene rubber bonded assembly is better solved at the room temperature by reducing the bonding molding curing pressure of the metal and nitrile butadiene rubber bonded assembly, the machining and producing cost is reduced effectively, the percent of pass of the products is increased, and the technology is suitable for popularization and application.

Description

Technical field [0001] The invention relates to the technical field of a low-pressure bonding process between nitrile rubber and metal, in particular to a room-temperature low-pressure bonding process between nitrile rubber and metal. Background technique [0002] In the field of aviation manufacturing, the manufacturing of bonding assemblies between certain metals and nitrile rubber is to bond the cleaned metal parts and nitrile rubber sheets or nitrile rubber profiles together through nitrile rubber adhesives. , Composing metal and nitrile rubber assembly for aircraft manufacturing and assembly. At present, the bonding between metal parts and nitrile rubber sheets or nitrile rubber profiles through nitrile rubber adhesives is performed under conditions of high temperature heating and high pressure during bonding. This bonding method is extremely difficult for the bonding and manufacturing of the metal and nitrile rubber bonding assembly, the processing and production are time-...
