Abstract

Abstract:

10-Undecenoic acid tetrafluoropropyl ester （UATE）, allyl polyether （F-6） and phenyl hydrogen-containing silicone oil were used as raw materials. Chloroplatinic acid was used as catalyst. The phenyl hydrogen-containing silicone oil co-modified with polyether and fluorine-containing ester （UAPFPS） was synthesized via hydrosilylation. The structure of UAPFPS was characterized by FT-IR and ¹H NMR. The optimum parameters were obtained by single factor experiment: the reaction temperature was 110 ℃; the reaction time was 5.5 h; n（Si-H） :n（C=C）=1:1.2; n（F-6） :n（UATE）=1:1; the amount of catalyst is 20 μg/g （relative to each gram of reactant）. Under this condition, the conversion of Si-H bonds was 95.30%. A modified silicone defoamer was prepared by compounding UAPFPS, silicone paste, emulsifiers and thickener. The results of performance test show that the defoamer has good defoaming properties, foam inhibition and stability.

Key words: long-chain fluorinated alkyl ester, phenyl hydrogen-containing silicone oil, hydrosilylation, defoamer
