Abstract
The invention discloses a styrene acrylic emulsion containing polyamidoamine dendrimer and a preparation method of the styrene acrylic emulsion. Deionized water, all emulsifier of sodium dodecyl benzene sulfonate and methanol are added into a four-necked flask according to weight parts of raw materials. The mixture is stirred at high speed until the emulsifier is emulsified sufficiently, N2 gas is introduced for protection, and stirring is carried out at constant speed. Then methanol solution of the polyamidoamine dendrimer is added, and at the same time, water bath heating is carried out. The monomers of styrene, methyl methacrylate and acrylic acid as well as potassium persulfate dissolved by deionized water completely are dripped into the flask respectively by two constant flow pumps when the temperature rises to about 80 DEG C. After the monomers and potassium persulfate are added, the mixture is keeped under the temperature for 1 hour and then heated to 85-95 DEG C for curing for 1h. The polymer emulsion is obtained when the heating is stopped and the mixture is stirred and cooled to room temperature. The emulsion provided by the invention has the characteristics of small average particle size and narrow size distribution, and can be used in the industrial fields of coating, textile, rubber and pharmaceutical industry.
Description
Technical field
The present invention relates to a kind of benzene emulsion that contains polyamide-amine dendrimer and preparation method thereof, can be used for industrial circles such as coating, weaving, rubber and medicine.
Background technology
In China, coating is utilized widely, but traditional coating environmental issue do rigorous inadequately; People's cognition is caused very major injury, and their sole mass is also very poor, work-ing life is short; Meeting the water capacity is prone to come off; Along with the development of society, people to the requirement of coating also in continuous raising, a kind of high-quality coating raw material of active demand.
Summary of the invention
Deficiency and defective in order to alleviate prior art the object of the present invention is to provide a kind of benzene emulsion that contains polyamide-amine dendrimer and preparation method thereof, and it is less that the emulsion of the present invention's preparation has median size, the characteristics of narrow diameter distribution; It can be used for industrial circles such as coating, weaving, rubber and medicine.
The present invention adopts following technical scheme to achieve these goals:
The benzene emulsion that contains polyamide-amine dendrimer, the weight part of its constitutive material is: deionized water 95-105, methyl alcohol 4-6, polyamide-amide type dendrimer 0.5-1.5, vinylbenzene 18-22, TEB 3K 6-10, vinylformic acid 4-6, Potassium Persulphate 0.3-0.5, X 2073 0.5-0.7.
The benzene emulsion that contains polyamide-amine dendrimer, the weight part of its constitutive material is: deionized water 100, methyl alcohol 5, polyamide-amide type dendrimer 1, vinylbenzene 20, TEB 3K 8, vinylformic acid 5, Potassium Persulphate 0.4, X 2073 0.6.
Contain the preparation method of the benzene emulsion of polyamide-amine dendrimer, may further comprise the steps:
75-85 part deionized water and whole emulsifying agent X 2073, methyl alcohol are added four-hole boiling flask, and the emulsification of high-speed stirring to emulsifying agent is abundant, feeds N
2Protection is at the uniform velocity stirred, and adds the methanol solution of polyamide-amide type dendrimer then; Carry out warming-in-water simultaneously, wait to be warmed up to about 80 ℃, drip into flask respectively by two constant flow pumps, control 0.5 hour and add with monomer styrene, TEB 3K and vinylformic acid and with the consoluet Potassium Persulphate of deionized water; After monomer and Potassium Persulphate dripped off simultaneously, insulation 1h was warming up to 85-95 ℃ of slaking 1h then; Stop heating, stir and be cooled to room temperature, promptly get polymer emulsion.
Beneficial effect of the present invention:
It is less that the emulsion of the present invention's preparation has median size, the characteristics of narrow diameter distribution; It can be used for industrial circles such as coating, weaving, rubber and medicine.
