Background technology
Foam is phenomenon common in live and work.But foam can bring great harm sometimes in industrial production, such as reduce machine operating efficiency, incur loss through delay working time, affect the quality of product etc.The method of eliminating harmful foam mainly contains physical method and chemical method, and defoamer froth breaking is one of chemical method.Along with the significantly raising of industrial enterprise's production scale and production efficiency, 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 exploitation and refining, coating, emulsion polymerisation, sewage disposal, metal cleaning, and defoamer has become indispensable functional aid in 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, also has good froth breaking ability and the lasting bubble ability that presses down simultaneously in the situation that consumption is very low, thereby, favored very much.
Defoaming composition is the core of defoamer, and its antifoaming speed and suds suppressing properties directly affect the performance of final products.For silicone based defoamer, the improvement of the antifoaming performance of its active matter is the improvement direction of silicone defoaming agent.The most original polysiloxane defoamers active matter is processed and is obtained through specific process technology by dimethyl silicone polymer and silica, as the defoaming agent composition that US3383327 introduces.But because it can not press down bubble lastingly, suds suppressing properties is poor, therefore, researcher both domestic and external has carried out large-scale expansion research to its performance.US4338217A1 replaces common polysiloxanes and silicon dioxide granule mixed processing to make defoaming composition with alkoxy polysiloxane; US5824739 introducing amino-polysiloxane or carboxyl polysiloxanes, as the main body of defoaming composition, obtain defoaming composition with silica mixed processing; EP163541B1 introduces with the polysiloxanes containing terminal hydroxyl and react formation side chain polysiloxane with the polysiloxane containing other active function groups under the effect of catalyst, and replace common polysiloxanes and hydrophilic silicon dioxide mixed processing with this, prepared defoamer formulations has very high viscosity, is difficult to this emulsion dispersion in water.US5153258 introduces and introduce the antifoaming performance that lightly crosslinked polysiloxane can improve composition in system, for example containing vinyl polysiloxane and hydrogeneous polysiloxane, hydroxyl polysiloxane and alkyl silicate, under the effect of catalyst, cross-linking reaction occurs, but crosslinking degree is difficult to control.US5486306 has introduced the hydrogeneous polysiloxane of a kind of direct use and α-olefine reaction synthesizes defoamer for washing powder, and this technique is synthetic simple, but the defoamer antifoam performance obtaining is poor, easily produces silicon spot with clothing in contact; In WO2007137948A1, introduced after hydrogeneous polysiloxane and the reaction of vinyl polysiloxane, the dimethyl silicone polymer dilution that adds trimethylsiloxy group end-blocking, when in above-mentioned patent, hydrogeneous polysiloxane and vinyl polysiloxane react, viscosity is large, wayward, the defoaming agent composition antifoaming performance obtaining is poor.CN1931417A discloses a kind of defoaming agent composition of high temperature resistant resistance to highly basic, it is obtained by polysiloxanes and organic siliconresin cross-linking reaction, active matter is prepared into after emulsion to bubbling test performance in black liquor, it has good suds suppressing properties, but antifoaming speed needs further to be improved, and, because defoaming composition viscosity is larger, be dispersed in water difficult.
EP-A341952 introduces and uses the silicone antifoam agent of branching and the composition of polyether-polysiloxane copolymers as defoamer, for pulp production.US5523019 introduces the composition of mineral oil and polyether-polysiloxane copolymers as defoamer, it is said and has positive effect.According to WO 98/000216, the siloxanes that contains dimethyl-3-hydroxypropyl-polyoxyethylene polyoxypropylene group is specially suitable surfactant in defoamer formulation.
The present invention reacts based on hydrogeneous polysiloxane and alpha-olefin, vinyl polysiloxane by a kind of, obtains having the alkyl-modified polysiloxane of following structure:
And adding amino-polysiloxane and silica, organic siliconresin mixed processing, the organosilicon defoaming composition obtaining, due to the existence of amino-polysiloxane, is easy to emulsification; With alkyl, to polysiloxane modification, improved the adhesion of organosilicon defoaming composition and organic material, made synthesizing organo-silicon emulsion there is good antifoaming performance in anion and nonionic system, and there is good flow leveling; Synthesis of solid particle defoaming agent, has slow release effect and foam and controls effect, in washing powder, adds, and has guaranteed that washing foam in early stage enriches, cleans up and washs later stage rinsing conveniently, the effect of water saving.Owing to having added therein amino-polysiloxane, amino-polysiloxane can improve fabric softness, has improved the affinity of solid particle defoamer and fabric, has reduced unnecessary trouble.
Summary of the invention
A kind of defoaming composition provides a kind of and reacts based on hydrogeneous polysiloxane and alpha-olefin, vinyl polysiloxane, and the defoaming composition that adds amino-polysiloxane, silica and organic siliconresin to obtain, can be used for the antifoam composition of organic silicon emulsion and solid defoamer.
