Product (hydrogen content is respectively 0.18,0.36,0.50,0.75wt%).
The hydrogen content of heretofore described containing hydrogen silicone oil can be by titration measuring, specifically can be according to following operation
It carries out: preparing the acetic acid solution 0.2mol/L of bromine first, then prepare 10% liquor kalii iodide, then prepare 0.1mol/L's
Hypo solution.The concentration for having demarcated sodium thiosulfate, is demarcated with potassium bichromate, finally samples containing hydrogen silicone oil 0.07g,
In the iodine flask of 250ml, add 20ml carbon tetrachloride, add the acetic acid solution of 10 milliliters of bromines, after standing 2 hours, adds 25 milliliters of iodine
Change potassium, is titrated to terminal with the sodium thiosulfate sodium just demarcated, hydrogen content can be calculated.
In some embodiments, the organosilicon levelling agent is prepared via a method which to obtain: by containing hydrogen silicone oil, function
Monomer and complex metal catalyst are added in reaction kettle, and mixed solvent is added and is dispersed with stirring, and reaction 2~4 is small at 60 DEG C
When, it discharges to obtain the final product.
The mixed solvent can select toluene, acetone, ethyl acetate, chloroform, N,N-dimethylformamide etc. it
Between compounding.
In some embodiments, the weight ratio between the containing hydrogen silicone oil and the function monomer is (2~3): 1；
Preferably, weight ratio 2.5:1.
In some embodiments, fluorine atom and/or epoxy group are also contained in the function monomer molecular structure.
The function monomer containing unsaturated double-bond, ester group and fluorine atom in the present invention can select fluoropropenes acid
Ester type compound, such as perfluor alkyl ethyl acrylate, trifluoroethyl methacrylate, methacrylate 1,1- dimethylbutyl
Ester etc..The function monomer containing unsaturated double-bond, ester group and epoxy group can be with glycidyl methacrylate, 2- first
Base -2- propylene -1- base 2- oxirane carboxylic acid ester etc..
In some embodiments, the function monomer containing epoxy group and described contain fluorine atom in the molecular structure
Function monomer weight ratio be 1:(0.8~1.8)；Preferably, the function list in the molecular structure containing epoxy group

It is found by the applicant that being used by the containing hydrogen silicone oil to specific hydrogen content has unsaturated double-bond, ester group, fluorine atom/epoxy
After the function monomer of the particular functional groups such as group is modified, preparing resulting organosilicon levelling agent has flowing well
Property, good levelling effect can be played by being added in the products such as coating, while can also significantly improve the overcoating performance of coating,
It is not in the problems such as interlaminar bonding is insecure when carrying out multilayer brushing.Itself the possible reason is, the levelling effect of levelling agent
Quality be mainly to be stood to be determined by the surface of polymer masses system, fluorine atom is introduced in levelling agent separation structure, and fluorine is former
The performances such as son has radius small, and electronegativity is strong, therefore introducing fluorine atom can be reduced largely in the link of high polymer
Surface tension in the polymer, to change the chemical property of polymer.Fluorine atom also has the characteristics that polarizability is low, electronics
Cloud can abut against around fluorine atom, and since the binding force between electrostatic force becomes smaller, the cohesiveness between C-F is smaller,
At by temperature the effects of, fluorine atom is easy to portion's migration from the inside, causes polymer surfaces tension small, improves coating
The flow leveling of fluid.
In addition, can't improve it is found by the applicant that although the introducing of fluorine atom can improve the levelling effect of coating
Its overcoating performance, and by the compounding of above-mentioned function monomer, while introducing the monomer containing ester group and fluorine atom, it is re-introduced into
A certain amount of function monomer containing epoxy group and ester group, can significantly improve the overcoating performance of coating.Its possible reason
It is epoxy group polarity with higher, the introducing of epoxy group helps to change organosilicon levelling agent in coating intramolecule
The aggregated structure presented, silicon atom and fluorine atom are towards the degree arranged on the outside of air when solidifying for Effective Regulation coating, together
When introduce it is some be easy to the attached polar component with other coating compositions of parent, so as to improve body overcoating performance.It has been found that this Shen
Please in organosilicon levelling agent flow leveling and overcoating performance in esters of acrylic acid coating improvement it is especially significant.
