Abstract
The invention discloses a silicon-free antifoaming agent specially used for waste water processing, and a preparation method thereof. The silicon-free antifoaming agent specially used for waste water processing comprises, by weight, 5 to 20% of a fatty alcohol, 1 to 3% of fatty acid monoglyceride, 3 to 6% of a high aliphatic alcohol polyether, 60 to 70% of white oil, 15 to 35% of emulsifier S-60, 1 to 3% of lauryl sodium sulfate, 1 to 3% of white carbon black, and 2 to 5% of aluminium oxide, wherein the carbon atom number of the fatty alcohol ranges from 3 to 10, and the molecular weight of the high aliphatic alcohol polyether ranges from 5000 to 10000. The silicon-free antifoaming agent is capable of defoaming quickly, is low in using amount, possesses excellent thermal resistance, acid and alkali resistance, polyelectrolyte resistance, high shear resistance; the basic characteristics of foaming systems are not influenced by the silicon-free antifoaming agent; and the silicon-free antifoaming agent is capable of solving a problem that demulsification is easily caused when common antifoaming agents are added into polyelectrolyte, strong acid, strong base, and high shear systems.
Description
Technical field
The present invention relates to defoamer field, more particularly to one kind is without the special defoamer of silicon waste water process and its preparation side
Method.
Background technology
Use chemical assistant in a large number in the water treatment procedures such as industrial production, domestic water, wherein these auxiliary agents are with surface
Based on activating agent, the technique end of water process can all produce substantial amounts of foam, these materials be all based on macromolecular compound,
The foam that they are formed in water enhances bubble film strength because of intermolecular absorption problem so that froth breaking becomes difficult, and
Traditional organic silicon defoamer consumption is big, affects the fundamental property of the system of foaming, resistance to heat differential to have adverse side effect, therefore existing
There is defoamer performance to be improved；
Therefore, prior art has yet to be improved and developed.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide one kind is without the special froth breaking of silicon waste water process
Agent, it is intended to solve the problems, such as that prior art defoamer performance is to be improved.
It is a kind of to process special defoamer without silicon waste water, wherein：By weight percentage, including：
Fatty alcohol 5-20%；
Glyceryl stearate fat acid fat 1-3%；
Higher aliphatic polyethers 3-6%；
White oil 60-70%；
Emulsifying agent S-60 15-35%；
Lauryl sodium sulfate 1-3%；
White carbon 1-3%；
Aluminum oxide 2-5%.
Between 3-10, the molecular weight of higher aliphatic polyethers is between 5000-10000 for the wherein carbon atom of fatty alcohol.
A kind of preparation method without the special defoamer of silicon waste water process, wherein：Sequentially add fatty alcohol, the acid of glyceryl stearate fat
Fat, higher aliphatic polyethers, white oil, emulsifying agent S-60, lauryl sodium sulfate, white carbon, 30-60 point of aluminum oxide stirring
Clock is obtained without the special defoamer of silicon waste water process.Emulsifying agent S-60 is wherein added to be gradually added in batches.
The present invention's can be in industrial production, domestic water, consumption fast with froth breaking without the special defoamer of silicon waste water process
It is little, the fundamental property of the system of foaming is not affected, heat-resisting good, acid and alkali-resistance, resistance to polyelectrolyte, resistance to high shear, the present invention are solved
The defect of general common froth breaking agent emulsion easy breakdown of emulsion failure in polyelectrolyte, strong acid, highly basic, high shear system.The suds time
It is long, efficiency high, and it is nontoxic, corrosion-free, without adverse side effect.Low COD, low consumption amount, environmental protection.
