Description
Technical field
The present invention relates to a kind of preparation method of paper-making dispersant agent, be specifically related to a kind of preparation method of fast-solving polyacrylamide paper-making dispersant agent.
Background technology
At present, polyacrylamide is because containing carboxyl in molecular chain, and there is the capillary effect of reduction, contribute to moistening to solid of water, this is advantageous particularly for the dispersion in water such as fiber, filler, when polyacrylamide adds slurry, fiber, filling surface can be made to form bimolecular structure, extreme and the water of outer dispersion agent has stronger avidity, adds the degree that the solids such as fiber, filler are spontaneously wet out by water.Between the solid particulate such as fiber, filler because of electrostatic repulsion away from, reach good dispersion effect.Although anionic polyacrylamide dispersion agent is used widely because of cost advantage, and quality product is uneven, the problems such as ubiquity dissolution rate is slow, poorly soluble, easy degraded.
Summary of the invention
Object of the present invention is exactly the defect existed for prior art, a kind of preparation method of fast-solving polyacrylamide paper-making dispersant agent is provided, it is high and stable that this product has viscosity, solvability is good, and dispersion effect is good, anti-degraded, nontoxic, dissolution rate fast (having in 30min is that solubilized is complete, and the energy consumption that obvious shortening dissolution time and reduction dissolved product cause improves production efficiency).
The present invention is achieved through the following technical solutions:
By the acrylamide of 180-280 part, the sodium acrylate solution of 120-250 part, 0.5-2 part tensio-active agent, the additive of 10-20 part, 550-650 part deionized water is mixed with solution, proceeds to reactor after adjusting temperature, pH value; Pass into nitrogen, oxygen is eliminated, then add the chain-transfer agent of 0.03-0.06 part, the redox initiator of 0.08-0.12 part, the water-soluble azo class initiator initiated polymerization of 0.1-0.5 part; Obtain gum polymers after reaction terminates, by gum polymers granulator granulation, micelle carries out drying in 65-75 DEG C, namely obtains product after drying through pulverizer fragmentation.
The additive sodium vinyl sulfonate that the present invention introduces, improve the wetting ability of polymkeric substance and anti-degradation property, as paper-making dispersant agent, dispersion efficiency is high, and improves gloss and the surface property of coating; For paper, this coating makes its wear resistance be improved.
