ActiveCN110042667ASolve yieldSolve problems such as purification difficultiesCarbon fibresFiberCarbon fibers
The invention provides a preparation method of an isocyanate modified polyether silicone oil nonionic emulsion and a product and application thereof. The method comprises the steps of synthesizing double-end containing hydrogen silicone oil, synthesizing double-end hydroxyl modified silicone oil, synthesizing isocyanate modified polyether silicone oil, adding a proper amount of water for emulsifying, performing co-emulsifying with cationic amino modified epoxy silicone oil, and performing compounding to prepare a carbon fiber precursor oil agent. The technical problems met during an addition reaction of polyether modified silicone oil and high molecular weight polyethylene glycol monoallyl ether through containing hydrogen silicone oil that the reaction is difficult, the yield is low, theseparation purification is hard, and the color is dark are solved, and meanwhile the problems that the storage stability of amino modified silicone oil in the weak acid water phase is poor, compounding with cationic amino modified epoxy silicone oil is performed to prepare the carbon fiber precursor oil agent, after oiling, the carbon fiber precursor is stuck to rollers in the high-temperature drying and rolling process are solved.
