Description
Technical field
The present invention relates to paraffin wax emulsions technical field, more particularly to a kind of nano-titanium dioxide modified paraffin hybridisation emulsion
Preparation method.
Background technology
Paraffin wax emulsions are through emulsion reaction system by paraffin and several variety classeses, the emulsifying agent of performance and appropriate conditioning agent
Into solid-oil-water multiphase dispersion stable emulsion, without melting or dissolve when in use, it is resistance to antiacid, alkali resistant
The premium properties such as hard water, and the advantages of possess safe efficient, economic facilitate, it is widely used in building, rubber, papermaking, process hides etc.
In various industries.Although tool has been widely used, existing paraffin wax emulsions still have that stability is high, performance imperfection,
The problems such as effect is poor is used alone.To meet Shi Jishiyong demand, it is necessary to the property such as its abrasion resistance properties, water resistance and stability
Improvement can be made.
The content of the invention
The object of the invention be exactly in order to make up the defect of prior art there is provided a kind of wear-resistant, water resistance is excellent, it is stable
The preparation method of the high nano-titanium dioxide modified paraffin hybridisation emulsion of property.
The present invention is achieved by the following technical solutions：
A kind of preparation method of nano-titanium dioxide modified paraffin hybridisation emulsion, comprises the following steps：
（1）Butyl titanate by absolute ethyl alcohol and equivalent to absolute ethyl alcohol weight 10-20% is added in reactor jointly stirs equal
It is even, then add Tweens surfactant equivalent to absolute ethyl alcohol weight 50-100%, equivalent to absolute ethyl alcohol weight 100-
150% AEO and stearic acid equivalent to absolute ethyl alcohol weight 20-30% are uniformly mixed, and obtain Composite Milk
Agent；
（2）Paraffin is put into reactor in 65-85 DEG C of heating melting, the step of then adding equivalent to paraffin weight 5-10%
（1）The compound emulsifying agent stirs, and obtains emulsified wax；
（3）It first will be equivalent to step（2）The acetum of the emulsified wax weight 15-25% adds in emulsified wax 85-95 DEG C
First time stirring is carried out, the acetum equivalent to emulsified wax weight 30-40% is added after cooling and carries out second of stirring,
Nano-titanium dioxide modified paraffin hybridisation emulsion is obtained, the mass fraction of the acetum is 1-1.5%.
Described AEO is peregal O-25.
Described Tweens surfactant is Tween-80.
The step（2）In stirring condition be：Speed of agitator 1000-1500r/min, mixing time 15-30min.
The step（3）Middle first time stirring condition is：1000-1500r/min, 10-15min.
The step（3）In second speed of agitator be 400-600r/min.
It is an advantage of the invention that：
Butyl titanate, emulsifying agent are first well mixed by the present invention with the paraffin melted, are then emulsified paraffin, in paraffin
Hydrolysis generation titanium dioxide occurs for butyl titanate while emulsion dispersion, so that inorganic material nano titanium oxide be attached to
Inorganic-organic hybridization emulsion is obtained in paraffin wax emulsions, the property such as water resistance, wearability and intensity of paraffin wax emulsions is on the one hand improved
Can, on the other hand the combination due to nano titanium oxide in paraffin-water termination, reduces the aggregation of paraffin drop, carries
The high stability of the oil-water interfacial film of paraffin wax emulsions, so as to improve the stability of paraffin wax emulsions.Nanometer prepared by the present invention
Titania modified paraffin hybridisation emulsion has excellent abrasion resistance properties and water resistance, has good stability, and durability is high, practical
Property is strong.
