Abstract
The invention relates to an industrial organic silicon defoamer. The industrial organic silicon defoamer is prepared from the following raw materials in parts by weight: 80-150 parts of dimethicone, 2-8 parts of methyl-p-hydroxybenzoic acid, 15-28 parts of hydroxyethyl cellulose, 10-30 parts of monoglyceride fatty acid ester, 12-25 parts of polyethylene glycol fatty acid ester, 60-100 parts of polydimethylsiloxane and 800-1500 parts of water. The industrial organic silicon defoamer developed by the invention has the beneficial effects that a synthetic process of the traditional defoamer is replaced, the cost is lowered, the environment protection quality is improved, a technical support is provided for the energy conservation and emission reduction of enterprises, the popularization and use values are relatively high, and the technical progress is demonstrated.
Description
Technical field
The present invention relates to a kind of chemical assistant, and in particular to a kind of industrial organic silicon defoamer, belong to coating technology neck
Domain.
Background technology
In most industrial processes, a large amount of bubbles for producing can make troubles, for example, affect production efficiency, cause to set
Standby to damage, production is even resulted in when serious cannot be carried out, in industrial wastewater, sanitary sewage, electroplating wastewater, dyeing waste water, petrochemical industry
The field of industrial waste water treatment such as waste water, sugar production wastewater, starch wastewater, alcohol effluent, black liquid, the impact of bubble is particularly general
Time, it is required to solve the problems, such as froth breaking.Froth breaking in wastewater treatment process belongs to water-based system froth breaking, and at present conventional defoamer is more
For organic silicon defoamer, low cost good with water-based system compatibility that it has and surface tension are low, froth breaking is rapid, the suds time
The characteristics of harsh conditions, wide adaptabilities such as length, volatility little, high temperature resistant.
The organic silicon defoamer applied in water-based system is generally emulsion form, will be insoluble in the organosilicon isoreactivity of water
Material makes emulsion oil-in-water by the emulsification such as emulsifying agent, water, and after adding bubbling system, the organosilicon with defoaming activity can
In being effectively dispersed in water phase, froth breaking effect is given full play to.But existing organic silicon defoamer dilution stability and froth breaking persistence
, easily there is floating oil or breakdown of emulsion in difference, organosilicon therein is gradually disengaged in wastewater treatment process because waste water is subject to vigorous agitation
Separate out, make defoaming activity reduction, froth breaking persistence not good, often lead to need to repeat addition defoamer, so that wastewater treatment
Cost increases.
The content of the invention
The present invention provides a kind of industrial organic silicon defoamer, and low production cost, dispersiveness is fast, and defoaming capacity is strong, uses
The features such as scope is wide.Preparation method has process is simple, the characteristics of easy to operate.
For achieving the above object, the present invention employs the following technical solutions realization：
A kind of industrial organic silicon defoamer, the preparing raw material weight percent of the defoamer is consisted of：
80-150 parts of dimethicone,
2-8 parts of methyl para hydroxy benzoic acid,
15-28 parts of hydroxyethyl cellulose,
10-30 parts of mono-fatty acid glyceride,
12-25 parts of cithrol,
60-100 parts of dimethyl silicone polymer,
800-1500 parts of water.
Preferably, the preparing raw material weight percent of the defoamer is consisted of：
110 parts of dimethicone,
3 parts of methyl para hydroxy benzoic acid,
20 parts of hydroxyethyl cellulose,
20 parts of mono-fatty acid glyceride,
20 parts of cithrol,
80 parts of dimethyl silicone polymer,
1000 parts of water.
It is prepared by described dimethicone：Load band through octamethylcy-clotetrasiloxane, end-capping reagent and organic amine catalyst
In there are three mouthfuls of reactors of thermometer, agitator, nitrogen bubble stirring is passed through, the vacuum dehydration at 30 DEG C is polymerized at 80 DEG C
Afterwards, then it is warmed up to 150 DEG C, destroys catalyst, makes dimethicone standby.
Compared with prior art, the invention has the advantages that：The New type of orgarosilicon foam breaber that the present invention is developed,
Replace the synthesis technique of traditional defoamer, not only reduced cost but also improve the quality of environmental protection, reduce discharging for industry energy conservation and provide
Technical support, with higher application value, shows technological progress.
