[Abstract]:Methyl two dimethylamino ethyl methacrylate and acrylamide cationic emulsifier has been synthesized, and the synthesis of cationic emulsion, and then applied to inkjet printing, and the addition of crosslinking system and functional monomer emulsion to improve water resistance and stability. At the same time on the synthesis of maleic acid, emulsifier, main the research contents are as follows: (1) to two dimethylamino ethyl methacrylate as monomer, preparation of quaternary ammonium salt type polymer emulsifier, its use with sixteen alkyl three methyl bromide combined with styrene and butyl acrylate monomers, cationic acrylic emulsion has been prepared. The experimental results show that when the cationic polymer emulsifier and sixteen alkyl three methyl bromide mass ratio was 34.6:0.6, the most stable cationic emulsion. By adding different crosslinking systems on polymer Effect of cationic emulsion resistance and particle size, at the same time by infrared spectroscopy, differential scanning calorimetry, laser particle size analyzer were used to characterize the prepared emulsion. The experiment results show that adding functional monomer three glycol two methyl acrylate (V-389) emulsion crosslinking agent when the water resistance when the best. The amount of V-389 was 1.7% (for total monomer), emulsion water absorption rate reaches a minimum value of 3.62%, a good performance. (2) using acrylamide as main monomers, sixteen alkyl three methyl ammonium bromide as phase transfer catalyst, polymer cationic emulsifier was synthesized with styrene and butyl acrylate monomers, cationic acrylic emulsion has been prepared. The experimental results show that when sixteen alkyl three methyl bromide dosage is 1 g, dosage of acrylamide was 5 g, epichlorohydrin dosage is 5.2 g, the most excellent emulsifier emulsion in the preparation of cation. In the process of seed emulsion, adding different crosslinking systems to explore its impact on the water resistance and particle size, at the same time by infrared spectroscopy, differential scanning calorimetry, laser particle size analyzer were used to characterize the prepared emulsion. The results show that: when adding diacetone acrylamide - crosslinking system has two hydrazide radical crosslinking system was 1 g, water absorption rate reaches a minimum value (3 5.39%.) with two dimethylamino ethyl methacrylate polymer emulsifier were prepared by cationic polyacrylate emulsion and inkjet. Using transmission electron microscopy, differential thermal scanner shows, particle size analysis structure of polymer emulsion prepared by the instrument were characterized on ink absorbent polymers in ink-jet printing. The results show that the polymerization using core-shell emulsion, functional monomer N-hydroxymethyl acrylamide was 4.60% (for total monomer, the same below), allyltrimethoxysilane weight is 2.30%, DM 19%, three nm two aluminum oxide dispersion was 10.67% (accounting for total, the emulsion) ink receptity emulsion is best, play the picture most clearly. (4) the prepared acrylamide cationic emulsion and three with the use of two aluminum oxide, and applied to the image printing, print the image is clearly, at the same time using transmission electron microscopy in the emulsion was characterized. (5) with maleic anhydride and N, N- two methyl diethanolamine as reactants and sodium p-toluene sulfonate as catalyst, maleic acid two ethanol amine ester was synthesized with maleic acid two ethanol amine ester and then quaternization reaction with sodium chloroacetate. A new type of polymerizable maleic acid cationic monomers were synthesized. Using mixed indicator two-phase titration method for the determination of the conversion rate, at the same time by infrared spectroscopy and nuclear magnetic resonance spectroscopy on the structure of the product was analyzed. The experimental results show that maleic acid The molar ratio of two ethanolamine to sodium chloroacetate is 1:1.2, the reaction time is 6 h, and the reaction temperature is 70 degrees. The conversion rate of tertiary amine is up to 76.17%. at the same time. The cationic emulsifier made by the above homemade single system is applied to emulsion polymerization, and a stable cationic emulsion is prepared.
