Adhesion of textile fabric to butyl rubber

Claim 1

AN ADHESIVE COMPOSITION FOR THE ADHERING A SYNTHETIC RUBBERY COPOLYMER OF AN ISOOLEFIN HAVING 4 TO 7 CARBON ATOMS WITH 0.5 TO 10% OF AN OPEN-CHAIN CONJUGATED DIOLEFIN HAVING 4 TO 8 CARBON ATOMS TO TEXTILE MATERIALS, COMPRISING 100 PARTS OF SAID SYNTHETIC RUBBER PRE-REACTED WITH SUFFICIENT CURATIVE SELECTED FROM THE GROUP CONSISTING OF SULFUR, ULTRA ACCELERATORS OF SULFUR VULCANIZATION, DINITROSOBENZENES, P-QUINONE DIOXIME WITH AN OXIDIZING AGENT, AND 4-HYDROCABON-2,6-DIMETHYLOLPHENOLS TO INCREASE THE LINHORST PLASTICITY NUMBER BY FROM 0.002 TO 0.050 UNITS, FROM 15 TO 50 PARTS OF A NOVOLAC PHENOLFORMALDEHYDE RESIN AND A METHYLENE-YIELDING HARDENING AGENT THEREFOR SELECTED FROM THE GROUP CONSISTING OF HEXAMETHYLENETETRAMINE AND PARA-FORMALDEHYDE, AND SUFFICIENT ADDITIONAL CURATIVE SELECTED FROM THE AFORESAID GROUP TO VULCANIZE THE SAID PRE-REACTED RUBBER.

Claim 3

A METHOD OF ADHERING A SYNTHETIC RUBBERY COPOLYMER OF AN ISOOLEFIN HAVING 4 TO 7 CARBON ATOMS WITH 0.5 TO 10% OF AN OPEN-CHAIN CONJUGATED DIOLEFIN HAVING 4 TO 8 CARBON ATOMS TO A SYNTHETIC TEXTILE WHICH IS A RESINOUS, THEREMOPLASTIC, LINEAR POLYMER OF A HEXAMETHYLENEDIAMINE SALT OF ADIPIC ACID, COMPRISING PREPARING AN ADHESIVE BY PRE-REACTING 100 PARTS OF SAID RUBBER WITH FROM 0.25 TO 3 PARTS OF A 4-HYDROCARBON-2,6-DIMETHYLOLPHENOL AND FROM 0.1 TO 10 PARTS OF A HEAVY METAL CHLORIDE AT A TEMPERATURE OF FROM 235*F. TO 450*F., MIXING SAID PRE-REACTED RUBBER WITH FROM 15 TO 50 PARTS OF A CASHEW NUT SHELL OIL MODIFIED NOVOLAC PHENOL-FORMALDEHYDE RESIN AND HEXAMETHYLENETRAMINE AS A METHYLENE-YIELDING HARDENING AGENT THEREFOR, AND WITH SULPHUR AND AN ULTRA ACCELERATOR OF SULPHUR VULCANIZATION AS ADDITIONAL CURATIVE IN AMOUNTS SUFFICIENT TO VULCANIZE THE SAID PRE-REACTED RUBBER, INTERPOSING THE RESULTING ADHESIVE COMPOSITION BETWEEN THE SAID TEXTILE AND A VULCANIZABLE BODY OF THE SAID RUBBER TO BE ADHERED THERETO, AND CURING THE RESULTING LAMINATED TO FIRMLY ADHERE THE SAID BODY TO THE SAID TEXTILE.

Claim 4

A METHOD OF ADHERING A SYNTHETIC RUBBERY COPOLYMER OF AN ISOOLEFIN HAVING 4 TO 7 CARBON ATOMS WITH 0.5 TO 10% OF AN OPEN-CHAIN CONJUGATED DIOLEFIN HAVING 4 TO 8 CARBON ATOMS TO A SYNTHETIC TEXTILE WHICH IS A RESINOUS, THEREMOPLASTIC, LINEAR POLYMER OF A HEXAMETHYLENEDIAMINE SALT OF ADIPIC ACID, COMPRISING PREPARING AN ADHESIVE BY PRE-REACTING 100 PARTS OF SAID RUBBER WITH FROM 0.25 TO 3 PARTS OF A 4-HYDROCARBON-2,6-DIMETHYLOLPHENOL AND FROM 0.1 TO 10 PARTS OF A HEAVY METAL CHLORIDE AT A TEMPERATURE OF FROM 235*F. TO 450*F., MIXING SAID PRE-REACTED RUBBER WITH FROM 15 TO 50 PARTS OF A CASHEW NUT SHELL OIL MODIFIED NOVOLAC PHENOL-FORMALDEHYDE RESIN AND HEXAMETHYLENETRAMINE AS A METHYLENE-YIELDING HARDENING AGENT THEREFOR, AND WITH SULPHUR AND AN ULTRA ACCELERATOR OF SULPHUR VULCANIZATION AS ADDITIONAL CURATIVE IN AMOUNTS SUFFICIENT TO VULCANIZE THE SAID PRE-REACTED RUBBER, INTERPOSING THE RESULTING ADHESIVE COMPOSITION BETWEEN THE SAID TEXTILE AND A VULCANIZABLE BODY OF THE SAID RUBBER TO BE ADHERED THERETO, AND CURING THE RESULTING LAMINATED TO FIRMLY ADHERE THE SAID BODY TO THE SAID TEXTILE.
