Abstract

PURPOSE:To obtain a copolymer latex suitable as an adhesive for bonding rubber to fiber, by emulsion-polymerizing a conjugated diene monomer with an ethylenically unsaturated monomer and vinylpyridine so that the obtained copolymer may contain a specified amount of carboxyl groups on the surfaces of particles. CONSTITUTION:A copolymer latex obtained by emulsion-polymerizing 45-85wt% conjugated diene monomer with 10-45wt% vinylpyridine and 0-30wt% other monomers copolymerizable therewith, wherein the content of carboxyl groups on the surfaces of the latex particles is at least 0.01 meq. per gram of the copolymer. The amount of the conjugated diene monomer used is usually 45-85wt% based on the total weight of monomers, and when it is outside this range, the adhesive force is lowered. The amount of the ethylenically unsaturated monomer used is 0.1-25wt%. The amount of the vinylpyridine monomer used is usually 10-45wt% and when it is outside this range, the adhesive force is lowered.

In other words, if the rubber of the molded product contains vulcanization accelerators such as thiuram-based, sulfenamide-based, or guanidine-based, amine-based anti-aging agents, or natural rubber, for example, during long-term manufacturing of automobile tires. This is because polyester fibers have the disadvantage of deteriorating during the vulcanization process or during high-speed running of automobile tires, and their performance as reinforcing fibers is significantly reduced. In order to improve this drawback, we have improved the rubber compounding method by selecting a preferable vulcanization accelerator and anti-aging agent, and improved the polyester fiber itself by reducing the amount of terminal carboxylic groups contained in the polyester fiber. or ■ A method of pre-treating preester fibers with a compound containing a carboxyl group (for example, JP-A-55-166235

Next, 100 parts of Latex Man or Latex B was added thereto, and the mixture was reacted at 25° C. for 200 hours with stirring. Next is Palka? E (ICI Vulnax product Vul
30 parts of eabondE) were added. After adjusting this aqueous solution to a solid content concentration of 20%, polyester tire cord (1
500D/2) was subjected to immersion treatment. After the immersion treatment, heat treatment was performed at 240° C. for 1 minute. This treated polyester tire cord was sandwiched between natural rubber compounds prepared according to the formulation shown in Table 2, and press vulcanized. The adhesion between the tire cord and rubber was evaluated using the T adhesion test method (measurement temperature: 20°C, relative humidity: 65°C, 24 wire pull-out test).
