Rubber metal bonding refers to processes through which
rubber is adhered to a metal substrate. The metal gives the rubber enough
stiffness so the part can be mounted. Rubber provides the metal with
elasticity and damping properties. The rubber can be either adhered or
molded to a metal piece. Before the molding takes place, the metal is
prepared by degreasing, sandblasting or shot blasting in order to completely free the surface from rust and
other impurities. A bonding agent is then sprayed onto the piece of metal.
After drying, the rubber is placed into the mold for forming and curing.
In the rubber metal bonding process there are three essential elements:
rubber, the bonding agents and the substrate. Any type of rubber can
be used, providing that the material can flow into the mold without developing
a significant level of cross-linking and that the substances making up
the rubber material will not bleed rapidly to the surface of the uncured
stock. The bonding agents consist of polymer/solvent solutions, with
a primer coat based on phenolic-style resins and a topcoat of polymers
and other materials. Most of these solutions are patented. The thickness
of the bonding layer depends on the nature of the rubber formulation.
The application of the bonding agents typically requires the spraying
of a gray primer coat over a slightly wider area than the black topcoat,
using a barrel spraying machine. The substrate used in rubber metal bonding
services depends on the necessary strength and durability requirements
of the application.
The science behind the rubber metal bonding process is varied and complex.
Often the type of polymer (rubber) chosen depends on what type of metal
is to be used and/or the part being manufactured. Determining the appropriate
bonding agent is critical. The selection process depends on the rubber
to be used, the component design and the elasticity of the rubber. The
traditional metal used in rubber metal bonding services is steel in all
its forms and grades, but increasing use is made of aluminum alloys and
polyamides to save weight. Almost any material can be bonded to rubber,
provided that it can withstand the heat and pressures of the rubber
molding process. However, the results of bonding rubber to alloys, such
as bronze and brass, greatly depend on the composition of the alloys.
The pieces made by rubber metal bonding services are used in various
areas of the industrial, commercial and medical fields. Many of the components
are used for the isolation of vibration and noise in manufacturing applications. The motor vehicle industry in
particular uses a large number of bonded rubber to metal parts. The steering
wheel is joined to the steering column by various rubber bonded parts.
Foot pedals and bumpers are examples of common items that have rubber/metal
characteristics. Because of the wide variety of parts used today consisting
of bonded rubber to metal, most of the shops that specialize in the manufacturing
of these parts are custom shops that work with customers from the design
level through production.
Bonding rubber to metal is a process that requires adhering or molding the rubber to sandblasted metal.
Chemical curing
is a method in which an agent is applied to the surface of the lining
and allowed to permeate the lining over several days at room temperature.
The chemical curing process thatcan be accelerated by the application
of heat, is commonly used on tank repairs or large field lined vessels.
Exhaust steam curing
is a method in which the vessel is blanked off with blind flanges or
tarped with live steam being bled into it. The exhaust steam method
maintains the lining integrity and bond and is often used on field lined
tanks that are too large to transport.
Gaskets are
pieces or rings of rubber or metal placed at a joint to make it leakproof.
Gaskets are
a type of seal made often with bonded to metal rubber.
Induction heating
provides reliable, repeatable, non-contact and energy-efficient heating
in a minimal amount of time to very small areas within precise production
tolerances without disturbing individual metallurgical characteristics.
The closed-loop control of induction heating produces repeatable, rapid
and accurate heating cycles, making it ideal for in-line production
processes.
O-rings are
made of rubber or silicone and seal rotating or sliding shafts. O-rings,
often made with a rubber coating on metal, are used in applications
such as shock absorbers and differentials.
Piping is sometimes
bonded with rubber when the pipe line is required to be more insulated
and vibration absorbent.
Press bonding
is a non-heat or chemical way of bonding rubber to metal that involves
the bonding of a preformed rubber piece onto a piece of metal via a
predetermined groove or space and a mild adhesive agent.
Rubber bonding is a manufacturing process that adheres rubber to various materials in order to give the material elastic qualities.
Rubber grommets
are common devices made by the bonding of rubber to metal. Rubber grommets
are used in the screen press process, in the hoisting of a flag and
other applications in which an eyelet is needed for passing a line through.
Rubber products are those goods made from natural and synthetic rubbers materials.
Rubber
rollers are used to squeeze the water out of pulp in the manufacturing of paper.
The roll has a metal core, but to perform efficiently, the core is
lined
with rubber.
Seals are common
types of products made with rubber bonding technology. Seals are
often used as shut off pieces in hydraulic equipment.
Vulcanizer curing
is a rubber to metal bonding method in which a rubber lined metal article
is placed in a live steam vulcanizer and cured under pressure. The vulcanizer
method results in the highest rubber to metal adhesion and yields the
highest density for corrosive media.
Rubber to Metal Bonding Terms
Accelerators –
Chemicals which are added to rubbers to accelerate the rate of vulcanisation.
Rubber without accelerators takes 20-30 times longer to cure.
Activators – Chemicals added
to rubber to activate curing.
Adhesion – The propensity of
rubber to bond to a contact surface.
Adhesive – Material that can
be used to adhere or stick one surface to another.
Bonding – Joining of identical
or different types of material by means of an adhesive, creating a positive-substance
bond throughout the entire surface of the joint.
Bond Strength – Unit load,
applied in tension, compression, flexure, peel, impact, cleavage or
shear, required to break an adhesive assembly with failure occurring
in or near the plane of the bond. Rubber Metal Bonding strength is measured in pounds
per square inch (psi).
Break-Out – Force necessary
to actuate sliding. A high break-out value indicates the development of
adhesion.
Coating – A uniform layer of
chemical primers or adhesives that are used to produce chemical bonding
between rubber and a substrate.
Cold Bond – The adhesion of
a vulcanized rubber material to a contact surface through the use of suitable
contact cements.
Contact Pressure – Pressure
applied to the assembly to achieve a bond in contact adhesives.
Curing – Also known as “vulcanization,”
this is the permanent change that the rubber undergoes during molding.
Elastomer – Any material that
when stretched more than twice its length is able to return to its original
shape.
Flex Cracking – The tendency
of some Rubber Metal Bonding materials to crack as a result of repeated bending or stressing
at the same point.
Natural Rubber – Crude rubber
obtained from organic sources, such as vegetables.
Nitrile – Also referred to as
“Buna-N,” it is the most commonly used elastomer for O-rings,
due to its wide temperature range, resistance to petroleum fluids and
good physical properties.
Polymer – General term used
to describe all rubbers and plastics involved in Rubber Metal Bonding. Polymer is also the chemical term
that refers to all organic materials that are formed from chains of repeated
chemical units.
Primer – Chemical material that
improves the bond of the sealant to the substrate.
Set – Also called "permanent
set," it is the degree to which a rubber does not fully recover to
its original shape after it has been deformed for a long period of time.
Substrate – Any surface to which
a coating or sealant is applied.
Vulcanized Bond – A bond formed
between an elastomer to a primed surface through the used of heat and
pressure. The elastomer is vulcanized at the same time as the bond.
