Multifunctional waterborne additive with wetting and thickening functions, and manufacturing method thereof

The invention discloses a multifunctional waterborne additive with wetting and thickening functions, and a manufacturing method thereof. The multifunctional waterborne additive comprises, by mass, 5-20 parts of a nonionic wetting agent which is a propylene oxide-ethylene oxide copolymer F38, 1-10 parts of an anionic surfactant and a long-chain terminator which are sodium ricinoleate, 5-20 parts ofhydroxy organosilicon, 0-50 parts of an alcohol ether solvent PMA, 10-40 parts of a polyol, 5-30 parts of diisocyanates HDI and IPDI, 1-20 parts of a chain extender diol BDO, 2-20 parts of a carboxylglycol and 1-15 parts of amine. The additive can integrate two separate functions by chemical bonds in order to avoid performance interference and improve the stability, so multiple functions are realized by one additive, so the batching process is reduced, and the use cost is reduced. 一种具有润湿增稠多功能水性助剂及其制作方法，包括如下质量份数的原料：非离子型润湿剂环氧丙烷环氧乙烷共聚物F38用量5-20份、阴离子型表面活性剂和长链中止剂蓖麻油酸钠用量1-10份、羟基有机硅用量5-20份、醇醚溶剂PMA用量0-50份、多元醇10-40份、二异氰酸酯HDI和
