Abstract
The invention discloses a papermaking dispersant and a preparation method therefor. The papermaking dispersant contains the following ingredients in parts by weight: 100-150 parts of toluene, 150-250 parts of sodium acrylate, 20-30 parts of styrene, 20-50 parts of acrylonitrile, 0.05-1 part of catalyst V65, 10-15 parts of mercaptoethanol, 5-8 parts of maleic anhydride and 80-100 parts of water. The papermaking dispersant has the advantages that the papermaking dispersant is high in viscosity, good in water solubility and high in dissolving speed, and produced paper sheets are high in quality and good in hand feeling; and meanwhile, the preparation method for the papermaking dispersant is easy and feasible and is shortened in production cycle, reduced in energy consumption, low in cost and easy to implement.
Description
Technical field
The present invention relates to a kind of chemical products, particularly relate to a kind of dispersion agent and preparation method thereof.
Background technology
Existing paper-making dispersant agent solvability is not high, water-soluble poor, and the paper quality of production is not high, can not meet the demand of existing market.
Summary of the invention
Goal of the invention: the first object of the present invention is to provide a kind of water-soluble paper-making dispersant agent higher with solvability; The second object of the present invention is to provide the preparation method of this paper-making dispersant agent.
Technical scheme: paper-making dispersant agent of the present invention, comprises the component of following weight part: toluene 100-150 part, vinylformic acid receive 150-250 part, vinylbenzene 20-30 part, the fine 20-50 part of propylene, catalyst V 650.05-1 part, mercaptoethanol 10-15 part, maleic anhydride 5-8 part and water 80-100 part.
Wherein, described toluene 120 parts, vinylformic acid receive 200 parts, vinylbenzene 25 parts, fine 30 parts of propylene, catalyst V 650.5 parts, mercaptoethanol 12 parts, maleic anhydride 7 parts and 90 parts, water.
First the preparation method of paper-making dispersant agent of the present invention, comprise the steps:, under 60-70 DEG C of condition, heating toluene, vinylformic acid are received and vinylbenzene, and the reaction times is 2-3h; Secondly, add all the other components and be slowly warming up to 80-90 DEG C, the reaction times is 1-2h, and cooling, stratification, filter to obtain decorating film, then dry and get final product.
Beneficial effect: compared with prior art, its remarkable advantage is in the present invention: this paper-making dispersant agent viscosity is high, good water solubility, dissolution rate fast, and the paper quality of production is high, good hand touch; Meanwhile, preparation method of the present invention is simple, the production cycle shortens, energy consumption reduces, with low cost, easily realize.
