Abstract
A defoaming composition is composed of a composition E composed of a hydrogen bond donor polyether modified polysiloxane C and a hydrogen bond acceptor X, and a composition F composed of a hydrogen bond donor fatty alcohol polyether D and a hydrogen bond acceptor Y; and the polyether modified polysiloxane C is composed of a polyorganosiloxane A and an allyl polyether B. The general structural formula of the polyorganosiloxane A is RHSiO (MeSiO)SiHR, where Ris C1-12 alkyl, cycloalkyl or aryl, and a=10-100. The general structural formula of the allyl polyether B is CH═CHCH(OCHCH)(OCHCHCH)OH, where b=1-10, and c=10-100. The general structural formula of the fatty alcohol polyether D is R(OCHCH)(OCHCHCH)OH, where Ris C3-20 linear or branched alkyl, cycloalkyl or aralkyl; m=1-50; and n=10-100. The hydrogen bond acceptors X and Y are menthol, menthene, thymol, terpilenol, carveol or perillyl alcohol.
