Specific implementation mode
The existing various exemplary embodiment that the present invention will be described in detail, the detailed description are not considered as the limit to the present invention
System, and it is understood as the more detailed description to certain aspects of the invention, characteristic and embodiment.
It should be understood that heretofore described term is only to describe special embodiment, being not intended to limit this hair
It is bright.In addition, for the numberical range in the present invention, it is thus understood that it is also specifically disclosed that every between the upper and lower bound of the range
A median.Median and any other statement value in any statement value or stated ranges or in the range in
Between each of between value smaller range be also included in the present invention.These small range of upper and lower bounds can include independently
Or it excludes in range.
Unless otherwise stated, all technical and scientific terms used herein has the routine in field of the present invention
The normally understood identical meanings of technical staff.Although the present invention only describes preferred method and material, the present invention's
Implement or can also be used and similar or equivalent any method and material described herein in testing.The institute mentioned in this specification
There is document to be incorporated by reference into, to disclosure and description and the relevant method of the document and/or material.It is incorporated to any
When document conflicts, it is subject to the content of this specification.
In the present invention, vocabulary of terms had both included singulative, also included plural form, unless context separately clearly refers to
Go out.Heretofore described "at least one" refers not only to the case where comprising "one" or "an", and prior also includes " more
It is a " or the case where " a variety of ".
As used in the present invention, term " interior wall sealing wax " is sometimes referred to as " water paint for internal walls ", " interior wall water-based composition ",
Refer to the paint vehicle or coating painted on wall indoors.Compared with painting in outdoor exterior wall paint, paint film is softer, water-resistant capacity
It is weaker.
As used in the present invention, term " sealing wax " refers to the coating composition for being dispersed or dissolved in aqueous solvent.Including, but not
It is limited to water-reducible coating and Water-dispersing coatings (or water-dispersible paint).Lotion is emulsified after referring to as water-reducible coating is
The coating that film forming matter is prepared, can be diluted in construction with water.Emulsion is that instigate solvent type resin to be dissolved in organic molten after wherein
In agent, then make the lotion that resin dispersion is formed in water by strong mechanical agitation with the help of emulsifier.As moisture
Scattered coating refers to the coating prepared as film forming matter using synthetic resin emulsion.Lotion refers in the presence of emulsifier, in mechanical agitation
During, the small particles group that unsaturated ethylene alkenyl monomer is polymerized under the conditions of certain temperature is dispersed in water point of composition
Dissipate lotion.
As used in the present invention, term " degree of branching " is calculate by the following formula：
Wherein " BP " is the degree of branching, and unit is percentage, and " a " is that have more than 2 reactive groups in each molecule

J.Am.Chem.Soc.113 describes the analysis method that the degree of branching is described using NMR in 4583,1991, which is based on
Dendroid unit, end unit and linear unit measure numerical value.
If all monomers of emulsifier are all simple function and difunctionality, the degree of branching is necessarily 0%.On the other hand,
If the degree of functionality of all monomers of emulsifier is all 3 or more, the degree of branching is necessarily 100%.As polyfunctional monomer amount increases
Add, the degree of branching also increases.
Without being bound by theory, it has been recognised by the inventors that emulsifier when emulsion polymerization of the present invention is amphiphilic, i.e. there is parent in one end
Oiliness, the other end have hydrophily.Lower in the degree of branching, hydrophobic group can be more closely deposited in micella, together
When hydrophilic radical can more closely be deposited in outside micella.These emulsifiers still remain in lotion after the completion of polymerization, film forming
After remain in paint film, compared with the high emulsifier of the degree of branching, after meeting water hydrophilic group be easier with water act on, promote water painting
It more permeates, spread and migrates in film, increase water absorption rate.Thus the water resistance of the paint film to obtaining has an adverse effect.
Based on this, the inventors discovered that, it is 50% or more, preferably 60% or more in the degree of branching of emulsifier, more preferably
70% or more；On the other hand, be 90% hereinafter, when in more preferable 85% or less range, emulsifier be it is Slight branching, thus
