Definitions
- This invention relates to a method for achieving adhesion between certain adhesive compositions and certain polyolefinic elastomers. More particularly, the invention relates to a method for achieving adhesion between certain chlorosulfonated polethylenes and non-polar polyolefinic elastomeric materials.
- Ethylene-propylene-diene terpolymers EPDM
- IIR isobutylene- isoprene copolymers
- compositions developed over the years for bonding olefinic elastomers have been based more often than not on halogenated elastomers or other halogen-containing film- forming resins.
- These compositions typically contain an aromatic nitroso compound such as dinitrosobenzene or a precursor of an aromatic nitroso compound such as quinone dioxime.
- the aromatic nitroso compounds or precursors are believed to act as crossbridging agents so as to form a linkage between the adhesive composition and the olefinic substrate being bonded.
- EPDM elastomer-to-metal assemblies Typical commercial applications for EPDM elastomer-to-metal assemblies include anti-vibration or anti-shock mounts and bushings for motor vehicles.
- EPDM is particularly well suited for assemblies that must do service at elevated temperatures and/or in the presence of oxygen.
- other widely used diene elastomers are prone to damage through oxidative scission of the polymer backbone, and in the case of natural rubber, to thermal reversion as well.
- EPDM elastomer- to-metal assemblies Another important automotive application for EPDM elastomer- to-metal assemblies is that of extruded EPDM window channeling or metal-supported weather strips.
- Sheet metal aluminum and gal ⁇ vanized steel are typical
- An appropriate primer and adhesive overcoat is normally coated with an appropriate primer and adhesive overcoat, dried and slit into continuous window channel substrate form.
- Compounded but uncured EPDM is then extruded onto the coated metal and bonded with heat that also drives the EPDM vulcanization reaction.
- Adhesives and primers for bonding EPDM window channeling are generally very similar to those selected for EPDM mount or bushing fabrication and generally comprise at least one halogenated or halogen-containing film-former and an aromatic nitroso compound or precursor.
- Adhesive compositions of this type are described in U. S. Pat. No. 3,282,883 (DeCrease, Shafer), and also in U.S. Pat. No. 4,119,587 (Jazenski, Manino). Both patents cite the use of chloro ⁇ sulfonated polyethylene as a suitable halogen-containing film-former, and dinitrosobenzene as a necessary ingredient.
- EPDM electrostatic deformation
- window channel applications it is often specified by the automobile manufacturer that the elastomer profile should be flocked, i.e. with polyester textile fibers.
- the protruding closely-packed fibers of a flocked extrusion enable a good seal to window glass that will be rolled up and down so that dirt and other refuse cannot enter the automobile door's interior.
- the flocked elastomer surface also presents little or no undesirable friction as the window glass moves against it.
- EPDM primer compositions used for flocking of extrusions can also be employed where it is desired to coat an elastomeric EPDM substrate.
- EPDM may be coated for aesthetic purposes such as white coatings for the EPDM sidewall of tires.
- Primer compositions for bonding EPDM are commercially available from LORD Corporation under the trade names CHEMLOK 236, CHEMLOK 459, andTS3320-19.
- the second approach for flocking EPDM extrusions involves adhesive compositions of the urethane type which adhere directly to the untreated EPDM surface.
- Adhesive formulations along such lines are the subject of U. S. Pat. No. 4,535,121 (Oezelli, Hofimann).
- the urethane type compositions typically rely on the use of aromatic nitroso compounds or precursors of the same type as employed in EPDM-to-metal adhesives.
- the present state-of-the-art offers adequately adhering EPDM primer, adhesive and coating compositions, the existing formulations do have deficiencies and disadvantages.
- One difficulty with certain state-of-the-art adhesives is that of blisters forming under the extruded EPDM after bonding. These blisters are believed to be due to decomposition products of the aromatic nitroso compounds used in such formulations.
- the present invention is based on the unexpected discovery that chlorosulfonated polyolefins having a chlorine content not greater than about 30 percent have an unusual and substantial affinity for non-polar polyolefinic elastomers.
- the present invention therefore relates to a method for achieving adhesion between an adhesive composition and a non-polar polyolefinic elastomer comprising contacting the adhesive composition with the surface of the non-polar polyolefinic elastomer at an elevated temperature sufficient to effect adhesion wherein the adhesive composition consists essentially of a chlorosulfonated polyolefin having a chlorine content of between about 5 and 30 percent.
- the present invention relates to a method for achieving adhesion between an adhesive composition and a non-polar polyole ⁇ finic elastomer comprising contacting an adhesive composition with the surface of the non-polar polyolefinic elastomer at an elevated temperature sufficient to effect adhesion wherein the adhesive composition consists essentially of a chlorosulfonated polyolefin having a chlorine content of between about 5 and 30 percent.
- NPP elastomers suitable for utilization in the method of the present invention can essentially be any elastomeric olefin copolymer which has residual carbon-to-carbon unsaturation.

- EPDM is prepared from ethylene monomers, propylene monomers and diene monomers.
- the diene monomers utilized to prepare the EPDM may be any diene monomer copolymerizable with ethylene or propylene monomers so as to provide residual unsaturation, preferably residual side-chain unsaturation in the resulting polymer.
- diene monomers include 1,4-hexadiene, ethylidene norbornene, and dicyclopentadiene, with 1,4-hexadiene and ethylidene norbornene being preferred.
- the NPP elastomer can be in essentially any form that will enable it to receive an adhesive composition.
- the NPP elastomer can be in the form of a block, strip, or sheet such as obtained by transfer or injection molding of the uncured NPP elastomer.

The solvent is then stripped to obtain a latex having a total sohds contents of from about 10 to 60, preferably from about 25 to 50, percent by weight.
- the chlorine content of the chlorosulfonated polyolefin is crucial to the adhesive bonding performance obtained by the method of the present invention. Specifically, it has been determined that chlorosulfonated polyolefins having a chlorine content not greater than about 30 percent have a surprisingly and unexpectedly superior affinity for NPP elastomeric materials. Accordingly, the chlorosulfonated polyolefin of the present invention must have a chlorine content of between about 5 and 30 percent, preferably between about 18 and 26 percent.

- An EPDM elastomer compound was prepared from the following ingredients:
- An adhesive overcoat having a non-volatile content of about 17 percent was prepared from the following ingredients using a high speed mixer (KINETIC DISPERSION CO., Laboratory model).
- a conventional metal primer composition (CHEMLOK 205 - Lord Corporation) was applied by dipping (and in accordance with the supplier's recommendations) to vapor-degreased grit-blasted steel coupons (dry film thickness 0.2 mil). The primed coupons were then dipped in the adhesive overcoat detailed above. Dry film thickness for the overcoat was approximately 1.3 mils.
- the bonded assemblies were tested by ASTM D429-B (modified for 45° peel angle) at a tensile tester jaw speed of 2" per minute.
- the resulting bond quality was 100% elastomer-tearing (no interfacial failure) at a pull value to failure of 90 lbs. (average).

- a second EPDM elastomer compound was prepared from the following ingredients:
- Tetramethyl thiuram monosulfide 1.5 ( a ) EPSYN 55 (Copolymer Corp.)
- HYPALON 45 was increased from about 17% to about 22% by slightly reducing the amount of xylene.
- Pads 1/8" thick of the same EPDM compound as used in Example 1 were vulcanized in a press for 20 minutes at 160°C.
- the same adhesive overcoat of Example 1 was painted onto two 1" strips of these pads with a paint brush, and the coated strips were air-dried.

- the adhesives were made up at a constant ratio of 5.56 parts of carbon black to 11.20 parts of the chlorosulfonated polyethylene in xylene. Non-volatile contents of the several adhesives were in the range of 17-24%, but all adjusted to give approximately the same dry film thickness after dipping.
- Laminates were prepared using the same vulcanized EPDM and same laminating procedure as in Example 4 except that the heat cycle in this case was 10 minutes at 144°C. Duplicate laminate samples for each adhesive were tested. Results were as follows:
- a white coating formulation was prepared by ball milling the following ingredients.

- the resulting cured white coating was very tough and elastomeric and was adhered so strongly to the EPDM substrate as to be almost impossible to remove by scraping with the sharp point of a knife.
- HYPALON 45 in the form of an aqueous dispersion at 40.4% non-volatile content was obtained from SUMITOMO SEIKA CHEMICAL CO. in Japan. This waterborne dispersion was designated by the supplier as CMS LATEX 450.
- the latex was diluted with deionized water to 17.9% non-volatile content. It was painted onto vulcanized strips of the same EPDM compo ⁇ md as used for Examples 4 and 5. The coated and dried strips were placed face-to-face in a PRECO PRESS under 15,000 lbs platen pressure with 4" diameter ram, and were then heated at 138°C for 10 minutes. The 1" laminated strips were tested for peel strength in a laboratory tensile tester with jaw speed separation of 20" per minute. Peel strength to rupture for two laminates averaged 37.5 lbs with failure 90% in the body of the elastomer and 10% failure interfacial to the adhesive and the vulcanized surface.
- a poly (dimethylsiloxane) emulsion designated DOW CORNING 346 Silicone Emulsion (60% non-volatile content) was blended as a surface friction reducing agent with the CMS LATEX 450 of the preceding example at a level of approximately five parts of silicone emulsion per 95 parts of CMS LATEX 450.
- the blend was coated onto a strip of the same vulcanized EPDM as used in Examples 4 and 5. After air-drying, the coated strip was heated for 10 minutes at 153°C. The resulting coating was well adhered to the elastomer substrate and showed a very low surface coefficient of friction which can be attributed to the silicone additive.
