Description
?
Technical field
The present invention relates to a kind of silicon composition that can be used for organic silicon emulsion.Therefore, the invention belongs to technical field of fine chemical preparations.
Background technology
Foam is common phenomena in the live and work.But foam can bring great harm sometimes in industrial production, for example reduce machine working efficiency, incur loss through delay working time, influence the quality of product etc.The method of eliminating harmful foam mainly contains physical method and chemical process, and the defoamer froth breaking is one of chemical process.Along with the significantly raising of industrial enterprise's industrial scale and production efficiency, the defoamer froth breaking is more widely used.At present, defoamer has been widely used in the industries such as papermaking, textile printing and dyeing, oil production and refining, coating, letex polymerization, sewage disposal, metal cleaning, and defoamer has become indispensable functional aid in the production process.
According to the difference of defoaming composition, defoamer is divided into mineral oil origin, polyether-type and several main types such as silicone based.Compare with other defoamers, poly organo siloxane defoamer stable chemical performance, side effect is little, and good froth breaking ability and the lasting bubble ability that presses down are also arranged under the very low situation of consumption simultaneously, thereby, favored very much.
Defoaming composition is the core of defoamer, and its antifoaming speed and suds suppressing properties directly influence the performance of the finished product.For silicone based defoamer, the improvement of the antifoaming performance of its actives is the improvement direction of silicone antifoam agent.The most original polysiloxane defoamers actives is handled through specific process technology by polydimethylsiloxane and silicon-dioxide and is obtained, and the defoaming agent composition of introducing as US3383327 comes to this.But because it can not press down bubble lastingly, namely suds suppressing properties is poor, and therefore, domestic and international research personnel have carried out large-scale expansion research to its performance.US4338217A1 replaces common polysiloxane and silicon dioxide granule combination treatment to make defoaming composition with the alkoxyl group polysiloxane; US5824739 introducing amino-polysiloxane or carboxyl polysiloxane obtain defoaming composition as the main body of defoaming composition with the silicon-dioxide combination treatment; EP163541B1 introduces with the polysiloxane that contains terminal hydroxyl and form the side chain organopolysiloxane with the organopolysiloxane reaction that contains other active function groups under the effect of catalyzer, and replace common polysiloxane and hydrophilic silicon dioxide combination treatment with this, prepared defoamer has very high viscosity, is difficult to this emulsification is dispersed in the water.US5153258 introduces in system and introduces the antifoaming performance that lightly crosslinked organopolysiloxane can improve composition, for example contain vinyl organopolysiloxane and hydrogeneous organopolysiloxane, hydroxyl organopolysiloxane and alkyl silicate and under the effect of catalyzer, crosslinking reaction takes place, but crosslinking degree is difficult to control.US5486306 introduced the hydrogeneous organopolysiloxane of a kind of direct usefulness and α-
The synthetic defoamer of olefine reaction is used for washing powder, and this technology is synthetic simple, but the defoamer antifoam performance that obtains is poor, contacts with fabric and easily produces the silicon spot; After having introduced the reaction of hydrogeneous organopolysiloxane and vinyl organopolysiloxane among the WO2007137948A1, the polydimethylsiloxane dilution that adds the trimethylsiloxy group end-blocking, when hydrogeneous organopolysiloxane and vinyl organopolysiloxane react in the above-mentioned patent, viscosity is big, wayward, the defoaming agent composition antifoaming performance that obtains is poor.CN1931417A discloses a kind of defoaming agent composition of high temperature resistant anti-highly basic, it is obtained by polysiloxane and silicone resin crosslinking reaction, actives is prepared into test performance after the emulsion, it has suds suppressing properties preferably, but antifoaming speed remains further to be improved, and, because defoaming composition viscosity is bigger, be dispersed in the water it quite difficult.
The silicone antifoam agent of EP-A341952 introduction use branching and the composition of polyethers-polysiloxane copolymer are used for pulp production as defoamer.US5523019 introduces the composition of mineral oil and polyethers-polysiloxane copolymer as defoamer, it is said to have positive effect.According to WO 98/000216, the siloxanes that contains dimethyl-3-hydroxypropyl-polyoxyethylene polyoxypropylene group is specially suitable tensio-active agent in the defoamer formulation.The more difficult greatly emulsification of defoaming agent composition suds suppressing properties difference in the above-mentioned patent or viscosity.
The inventor finds to form in the process of silicon composition in hydrogeneous organopolysiloxane, silicone resin and the reaction of hydroxyl organopolysiloxane, if hydrogeneous organopolysiloxane is direct and the reaction of hydroxyl organopolysiloxane, do not react with silicone resin, the silicon composition crosslinking degree that obtains is excessive, and viscosity is difficult to control.If but hydrogeneous organopolysiloxane, hydroxyl organopolysiloxane and silicone resin are reacted jointly, the silicon composition suds suppressing properties that obtains is poor.
Summary of the invention
The present invention adds the hydroxyl organopolysiloxane by a kind of again based on hydrogeneous organopolysiloxane and silicone resin reaction, through the hydrophobic particles combination treatment, obtains silicon composition.Because the hydroxyl in hydrogeneous organopolysiloxane and the silicone resin reacts, make silicon composition have the siloxanes space structure of long-chain branch, improve the bonding force of silicon composition and organic materials, in being rich in the system of anion surfactant, foam has been had good inhibition effect after the synthesizing organo-silicon emulsion.
