초록 ▼

This invention relates to compositions useful as adhesives and more particularly to the preparation of heat-curable epoxy-based adhesive compositions that are resistant to being washed off substrate surfaces prior to being cured. The incorporation of a solid diene-based rubber, in particular an acrylonitrile-butadiene copolymer rubber having a relatively high Mooney viscosity, significantly enhances the wash-off resistance of the adhesive, while still allowing the adhesive to be readily dispensed by pumping under high shear conditions.

대표청구항 ▼

1. A pumpable and wash-off resistant epoxy paste adhesive comprising: A) at least one epoxy resin; B) from 1 to 8 weight %, based on the total weight of the epoxy paste adhesive, of at least one solid diene-based rubber, wherein the solid diene-based rubber does not take the form of a core/shell particle where a central core is surrounded by an outer shell having a different composition than the core and wherein the solid diene-based rubber is comprised of from 25 to 35 weight percent acrylonitrile and 65 to 75 weight percent butadiene; C) at least one heat-activated latent curing agent; and D) at least one impact modifier/toughening agent selected from the group consisting of epoxy-based prepolymers obtained by reacting one or more amine-terminated polymers with one or more epoxy resins. 2. The epoxy paste adhesive of claim 1 wherein said at least one solid diene-based rubber has a Mooney viscosity of from 50 to 100 at 100 degrees C. as measured by ASTM D-1646 (Method B-002). 3. The epoxy paste adhesive of claim 1 wherein said at least one solid diene-based rubber is crosslinked. 4. The epoxy paste adhesive of claim 1 additionally comprising one or more of: at least one thixotropic agent/rheology modifier; at least one heat-activated blowing agent; at least one impact modifier/toughening agent other than the at least one impact modifier/toughening agent selected from the group consisting of epoxy-based prepolymers obtained by reacting one or more amine-terminated polymers with one or more epoxy resins; or at least one inorganic filler. 5. The epoxy paste adhesive of claim 1 comprising at least one substituted guanidine heat-activated latent curing agent. 6. The epoxy paste adhesive of claim 1 additionally comprising at least one inorganic particulate additive selected from the group consisting of calcium oxide and calcium carbonate. 7. The epoxy paste adhesive of claim 1 wherein the at least one epoxy resin includes at least one polyglycidyl ether of a polyphenol and at least one polyglycidyl ether of a non-aromatic polyalcohol. 8. The epoxy paste adhesive of claim 1 comprising from about 30 to about 65 weight percent of epoxy resin. 9. The epoxy paste adhesive of claim 1 comprising from about 25 to about 60 weight percent epoxy resin and about 0.5 to about 10 weight percent heat-activated latent curing agent. 10. The epoxy paste adhesive of claim 1, wherein said at least one solid diene-based rubber is crosslinked. 11. The epoxy paste adhesive of claim 1, additionally comprising at least one anti-stringing agent. 12. The epoxy paste adhesive of claim 11, wherein the at least one anti-stringing agent is a mixture of amorphous silica and fibrillated polyethylene fibers. 13. The epoxy paste adhesive of claim 1, wherein the at least one epoxy resin includes at least one epoxy resin selected from the group consisting of diglycidyl ethers of bisphenol A and bisphenol F. 14. The epoxy paste adhesive of claim 1, wherein the at least one solid diene-based rubber includes at least one solid diene-based rubber having a Mooney viscosity of at least 25 and not more than 100 at 100 degrees C. as measured by ASTM D-1646 (Method B-002). 15. A method of making the epoxy paste adhesive of claim 1, comprising preparing a preblend of the at least one solid diene-based rubber and epoxy resin and combining the preblend with other components of the epoxy paste adhesive. 16. The method of claim 15, wherein the preblend additionally includes a particulate inorganic filler. 17. A method of increasing wash-off resistance of an epoxy paste adhesive comprised of at least one epoxy resin, and at least one impact modifier/toughening agent selected from the group consisting of epoxy-based prepolymers obtained by reacting one or more amine-terminated polymers with one or more epoxy resins, and at least one heat-activated latent curing agent, said method comprising incorporating into said epoxy paste adhesive from 1 to 8 weight percent, based on the total weight of the epoxy paste adhesive, of one or more solid diene-based rubbers, wherein the solid diene-based rubbers do not take the form of a core/shell particle where a central core is surrounded by an outer shell having a different composition than the core and wherein the solid diene-based rubber is comprised of from 25 to 35 weight percent acrylonitrile and 65 to 75 weight percent butadiene. 18. The method of claim 17, wherein the at least one anti-stringing agent is a mixture of amorphous silica and fibrillated polyethylene fibers. 19. The method of claim 17, wherein said at least one solid diene-based rubber has a Mooney viscosity of from 50 to 100 at 100 degrees C. as measured by ASTM D-1646 (Method B-002).
