The dispersion is prepared through adopting a long-chain alkyl siloxane component and a carboxyl silane component. The prepared dispersion is high in purity, good in product stability and wide in application range.
Description
Technical field
The present invention relates to polymeric material field, be specifically related to a kind of preparation method containing carboxyl chain alkyl silicone dispersion.
Background technology
The chain alkyl silicone dispersion containing carboxyl is group composition important in automotive coatings polishing agent, and the automotive polish VOC content that it is prepared is relatively low, and has high gloss, good pollution resistance and perception, preferable sense of touch performance.
Summary of the invention
Present invention aim at, it is provided that a kind of preparation method containing carboxyl chain alkyl silicone dispersion, the technical solution adopted in the present invention is:
A kind of preparation method containing carboxyl chain alkyl silicone dispersion, it is characterised in that it is prepared from carboxyl silicon components emulsion reaction by chain alkyl silicone components.
Further, described chain alkyl silicone components is prepared from by following steps:
A: join in reactor by 1 part of a-alkene, under nitrogen protection, is heated to 80 DEG C；
B: be slowly dropped into 1 part of containing hydrogen silicone oil, after 1-1.5h dropping, rises high-temperature to 120 DEG C；
C: being slowly dropped into isopropyl alcohol solution of chloroplatinic acid, 0.5-1h dropping is complete, insulation reaction 15h；
D: after reaction terminates, decompression is distilled off unreacted a-alkene, and processes through charcoal absorption, final acquisition chain alkyl silicone components.
Further, described carboxyl silicon components is prepared from by following steps:
A: by 12 parts of octamethylcy-clotetrasiloxanes, 1 part of r-the third amino methyl diethoxy silane, 5 parts of methyl dimethoxy epoxide dodecyl silane and 0.1 part of catalyst join in reactor, and oil bath is heated to 110 DEG C；
B: by 25 part 1,3,5-trimethyl cyclotrisiloxane are slowly added in reactor in 1h, and stirring makes it fully react 4h, then rise high-temperature to 150 DEG C, isothermal reaction 1h；
C: decompression is distilled off unreacted low-boiling-point substance, is cooled to 75 DEG C, is subsequently adding 0.8 part of maleic anhydride, continues reaction 1h, finally gives carboxyl silicon components.
The present invention provides the benefit that relative to prior art: the preparation method containing carboxyl chain alkyl silicone dispersion of the present invention, chain alkyl silicone components is used to be prepared from carboxyl silicon components, the dispersion purity prepared is high, and product stability is good, applied range.
