PURPOSE:To provide the titled two-pack type processing agent for bonding firmly chloroprene rubber to glass fiber, by formulating the first treatment to contain a silane coupling agent and the second treatment to contain resorcin, formaldehyde and a chloroprene rubber latex. CONSTITUTION:Glass fibers are treated with the first processing agent comprising a silane coupling agent (e.g. preferably one having the shown formula wherein R represents a group having vinyl, methacryl, acryl, allyl, epoxy, hydroxyl, mercapto or chloro and X represents a group capable of reacting with a siloxane or silanol), and then with the second processing agent containing resorcin, formaldehyde and a chloroprene rubber latex (preferably one obtained by mixing 100pts.wt. reaction product prepared by reacting 1mol of resorcin with 1-4mol formaldehyde and 100-1,100pts.wt. chloroprene rubber latex) and are bonded to chloroprene rubber by vulcanization. USE:Belt, hose, etc. |
