Problems solved by technology

[0004] The high-end water-based wetting agents and water-based thickeners on the market are all imported from foreign countries, and the water-based thickeners and water-based wetting agents are purchased separately, which are more expensive than oil-based and use a large amount, resulting in a sharp increase in the cost of water-based products
In addition, adding a variety of different additives will affect the stability of the system and interfere with other properties
[0005] At present, most high-performance water-based additives are monopolized by foreign production, the unit price is high, and they can only meet a single performance

Abstract

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.

Description

technical field [0001] The invention relates to a multifunctional water-based auxiliary agent, in particular to a multifunctional water-based auxiliary agent capable of wetting and thickening and a preparation method thereof. Background technique [0002] Traditional coatings are substances composed of resins, organic solvents, fillers and additives. The main function is to modify the effect of the surface of the item, such as adjusting the color, haze, feel, etc. Solvent needs to be added during manufacture and use. The use of organic solvents is harmful to the human body and the environment, so the state has increased the control of oily products. At present, the development direction of such products is mainly to reduce or eliminate organic solvents. Among various new environmentally friendly products, water-based products are used instead. Oil-based products are easier to achieve. However, due to the great difference in performance between water-based products and oil...
