Process for adhering a polyester fibrous material to a rubber
Реферат: 1,254,779. Bonding polyester material to rubbers. BRIDGESTONE TIRE K.K. 28 May, 1969 [4 June, 1968], No. 26868/69. Heading D1P. In a process for bonding a fibrous polyester material to natural or synthetic rubbers the material is immersed in an aqueous solution of triglycidyl isocyanurate, dried at 200- 250‹C, immersed in an aqueous solution of a resorcinol-formaldehyde resin and rubber latex solution, dried at 100-250‹C and finally contacted and vulcanized with the rubber composition. The material preferably takes up 0.01-15 parts by weight of solid (based on 100 parts by weight of material) from the first solution and 0.10-15 parts of the second solution. The first solution may also contain a second component either from a group consisting of amines, amine derivatives, amine regenerators of amines and amine regenerators of amine derivatives or from a group consisting of polybasic carboxylic acids and polybasic carboxylic acid anhydrides, the weight ratio of the first to the second component being in either case from 100:1 to 100:300.
