Description
Technical field
The invention belongs to auxiliary chemicals manufacture field, be specifically related to a kind of preparation method of macromolecule emulsifier.
Background technology
Emulsifying agent is generally divided into 3 kinds: traditional small-molecular emulsifier, reactive emulsifier and macromolecule emulsifier.Traditional small-molecular emulsifier can be brought final product into, and the surface at the process migration of emulsion film forming to film reduces glossiness and the water resistance of filming.Although the defect of small-molecular emulsifier can be avoided or overcome to reactive emulsifier, increased to a certain extent viscosity and the particle diameter of emulsion, the stability of system is reduced.Due to the structure of macromolecule emulsifier and the structure of water lustering oil basic identical, thereby greatly improved the consistency of macromolecule emulsifier and water lustering oil, reduced emulsion particle diameter, increased film forming glossiness.
Summary of the invention
The present invention has researched and developed a kind of macromolecule emulsifier, and object is: the tenderizer that a kind of environmental protection is provided.
This technical scheme:
A preparation method for macromolecule emulsifier, comprises the steps:
1), by polyisobutylene butanedioic anhydride 20-40 part, fatty alcohol-polyoxyethylene ether 20-40 part is carried out esterification under 20-30 degree Celsius of 450nm illumination;
2), reacting and obtaining preliminary emulsifying agent with the sodium hydroxide of 15-25 part ammonium persulphate and 20-40 part under 200-300 degree Celsius the polyisobutene succinic acid fatty alcohol-polyoxyethylene ether ester obtaining;
3), by step 2) in add linking agent and defoamer in the preliminary emulsifying agent that obtains.
Preferably, in described step 1), polyisobutylene butanedioic anhydride is 30 parts, 30 parts of fatty alcohol-polyoxyethylene ether.
Preferably, described step 2) in, ammonium persulphate is 20 parts, and sodium hydroxide is 30 parts.
Preferably, in described step 3), linking agent main component is Triethylenetetramine (TETA), dimethylaminopropylamine and diethyl amino propylamine any one and composition thereof.
Preferably, in described step 3), defoamer main component is organo-siloxane.
The invention has the beneficial effects as follows:
Institute of the present invention product property is stable, and reaction conditions is simple, and energy consumption is less, environmental protection, and sufficient raw, has production cost low, and turndown ratio is large, and production technique ratio is easier to the features such as realization.
