Description
Technical field
The present invention relates to a kind of preparation of efficient antifoaming agent of non-silicone of aqueous phase system use, defoamer is a kind of fine chemicals additive.Therefore, belong to technical field of fine chemical preparations.
Background technology
In national economy is produced, used a large amount of chemical assistants as people in the processes such as textile printing and dyeing, coating, papermaking, cleaning, metal processing, in the hope of having reached different purposes, but because employed auxiliary agent is based on surfactant, their drawback is exactly to produce a large amount of foams, and is especially serious with anion and non-ionic surface active agent.The untimely elimination of these harm foams meeting produces serious influence to subsequent handling, is easy to cause the instability of product.At this problem, relatively high-efficiency method is to add defoamer in the foaming system at present, defoamer at first must possess lower surface tension as a kind of auxiliary agent, be easy to sprawl on the surface of vacuolar membrane, thereby cause the uneven collapse of bubbles that causes of vacuolar membrane intensity.General defoamer must possess antifoam performance and suds suppressing properties, antifoam performance is meant that mainly defoamer can be very fast with the foam elimination that produces, and suds suppressing properties refers to mainly how long the froth breaking activity of defoamer in the foaming medium can be kept, if activity descends significantly, then the effect of defoamer also just loses.
