Description
Technical field:
The present invention relates to the preparation method of a kind of modified polyacrylate emulsion, have particularly to a kind of shell
The preparation method of the microsphere modified polyacrylate dispersion of hollow zinc of laminated structure.
Technical background:
Hollow structure material is a kind of novel partculate material grown up in twentieth century five, the sixties, quilt
It is widely used in the fields such as medicine controlled releasing, light absorption, microcapsule encapsulation, water process, catalysis, biochemistry.
Zinc oxide owing to pattern is various, structure-controllable and there is numerous special physical and chemical performance, therefore in
Hollow structure Material Field receives much concern.At present, the method preparing hollow zinc mainly has template, Ao Si
Special Grindelwald ripening method and chemical etching method.For template, use Ostwald ripening method
Prepare hollow ZnO microsphere with chemical etching method and have the advantage that first, low cost, it is not necessary to mould material;
Secondly, operating process is simple, can avoid going in template the process of removing template.But both approaches institute
The hollow zinc pattern of preparation is not easy to control, especially with regard to the system of the hollow zinc of specific morphology
For being also rarely reported.
Polyacrylate is because of its wide material sources, with low cost, has good cohesiveness, resistance to tortuosity etc. excellent
Point, becomes the filmogen being most widely used in leather finishing agent.But its film forming is fine and close, causes health
Performance reduces, and then affects the comfort level of leather goods dress.Therefore, researcher is poly-for how to improve
The water vapor permeability of acrylate coatings expands substantial amounts of work.Mainly include following two aspect: one is to adopt
Use inorganic nano particle modified polyacrylate dispersion, utilize the nanoparticle with the interface of organic alternate formation to be
Coating provides more vapor channel, but the method promotes amplitude the most not quite.Two to be that utilization itself has good
The protide filmogen modified polyacrylate of good sanitation performance, thus improve the saturating of polyacrylate coatings
Steam, (Gan Changfeng, Xu Qunna, Zhou Jianhua, etc. ternary amphipathic copolymer is prepared hud typed as emulsifying agent
Modified Casein Leather finishing agent [J]. Chinese leather, 2013,42 (5): 37-41.) but protide film forming material
Material poor water resistance, rub resistance and mechanical property be not poor.
Summary of the invention:
It is an object of the invention to provide a kind of shell and there is the hollow zinc microsphere modified poly-third of laminated structure
The preparation method of olefin(e) acid ester emulsion, not only has after modified polyacrylate emulsion film prepared by employing the method
There is good water vapor permeability, and there is certain resistance to water and mechanical property.
For achieving the above object, the present invention adopts the following technical scheme that:
1) by the Zn (NO of 2/3 consumption3)2·6H2O is miscible in deionized water with hexamethylenetetramine, and in
React 5min at 81~84 DEG C, be subsequently adding the sodium citrate of 2/3 consumption, after insulation reaction 1.1~1.5h, add
Enter the Zn (NO of residue 1/3 consumption3)2·6H2O and hexamethylenetetramine, and at 86~90 DEG C, react 5min
After, adding the sodium citrate of residue 1/3 consumption, after reaction 10min, regulation pH value is 9.2~10.8, then
Insulation reaction 3~5h at 86~90 DEG C, then through washing, be dried to obtain shell there is the hollow of laminated structure
ZnO microsphere;Wherein, Zn (NO3)2·6H2O, hexamethylenetetramine, the quality of total consumption of sodium citrate
Than being (0.624~1.2075): (0.2775~0.5685): (0.0225~0.2985);
2) shell is had the hollow zinc microsphere of laminated structure in deionized water after ultrasonic disperse, add
Entering in polyacrylate dispersion, stirring also reacts 6~8h at 75~80 DEG C, obtains shell and has laminated structure
The microsphere modified polyacrylate dispersion of hollow zinc;Described shell has the hollow zinc of laminated structure
Microsphere is (0.030~0.160) with the mass ratio of polyacrylate dispersion: 30.
Described Zn (NO3)2·6H2The gross mass of O and the mass ratio of deionized water are (0.624~1.2075): 70.
Described pH value uses ammonia or sodium hydrate aqueous solution to be adjusted.
Described being dried is to be dried 8~12h under the conditions of 60~80 DEG C.
The solid content of described polyacrylate dispersion is 30%.
During described ultrasonic disperse, shell has the hollow zinc microsphere of laminated structure and the quality of deionized water
Than being (0.030~0.160): 15.
The time of described ultrasonic disperse is 10~20min.
Described mixing speed is 350~450rpm.
Compared with prior art, the invention have the benefit that
(1) present invention utilize alkaline etching mechanism and Ostwald ripening mechanism prepare shell have lamellar knot
The hollow zinc microsphere of structure, technique is simple, low cost, and reaction condition is gentle, repeatable strong and productivity
High;The hollow zinc microsphere pattern that prepared shell has laminated structure is homogeneous.
(2) by physical blending process, shell is used to have the hollow zinc microsphere of laminated structure to polypropylene
Acid esters emulsion is modified, and utilizes the Large ratio surface that its hollow structure inside, shell laminated structure intertexture is formed
And the huge interface between the intrinsic performance characteristics of roughness, zinc oxide and zinc oxide and polyacrylate, promote
The combination property of polyacrylate coatings.Compared with virgin pp acid esters film, changed by the method for the present invention
Water vapor permeability and the resistance to water of the polyacrylate dispersion film of property can improve simultaneously, and water vapor permeability carries
High by 51%, resistance to water improves 11.61%, and tensile strength improves 60.26%.
Further, by ammonia or sodium hydroxide to the zinc hydroxide in hydroxide zinc/zinc oxide complex microsphere
The self assembling process of preferential etching and the growth of Zinc oxide nanoparticle oriented adsorption forms shell and has lamellar knot
The hollow zinc microsphere of structure so that prepared shell has the hollow zinc microsphere pattern of laminated structure
Homogeneous.
