摘要
封端型水性聚氨酯固化剂是现阶段汽车工业的重要研究内容,其在汽车滤纸中的应用,能够有效提高滤纸的硬挺度和耐水性。基于此,文章研究了以甲苯二异氰酸酯、聚丙二醇作为反应原料,NaHSO_(3)作为封端剂,结合乳化剂的使用所制备成的新型封端型水性聚氨酯固化剂,凭借其简单的合成方法和低成本优势,提高滤纸品质。
End-sealing waterborne polyurethane curing agent is an important research content in the automobile industry at present.Its application in automotive filter paper can effectively improve the stiffness and water resistance of filter paper.Based on this,this paper studied toluene diisocyanate,polypropylene glycol as reaction raw material,NaHSO_(3) as a sealing agent,combined with the use of emulsif ier prepared into a new type of water-borne polyurethane curing agent,with its simple synthesis method and low cost advantage,improve the quality of filter paper.
