Abstract
The invention discloses a method for producing a modified rosin sizing agent, and the product belongs to the field of papermaking chemical engineering. The modified rosin sizing agent is produced by taking modified rosin resin, paraffin, oxidated polyethylene, an emulsifier, a salt of rosin acid, a polymeric dispersant PEG 4000, an organic bromine bactericide, stearic acid, a rosin type surfactant as raw materials and taking an agitator tank as the equipment. The production method has a series of advantages of simple technology, low raw material price, good product quality and the like. The product can be added into paper slurry during beating or proportioning as an internal sizing agent, and is capable of effectively improving paper performances such as water resistance, oil resistance, printing ink resistance and the like, and also is capable of improving slipperiness, hydrophobicity and printing adaptability.
Description
Technical field:
The invention belongs to the papermaking chemical field, relate in particular to a kind of production method of paper grade (stock) modified rosin sizing agent.
Background technology:
Sizing agent is a kind of additive for paper making, also deserves to be called jelly, can give the anti-China ink of paper, water resistant, anti-emulsion, the performance such as anticorrosive, and can improve smoothness, intensity and use the phase.Applying glue has two kinds of methods, a kind of is when making beating or batching, sizing agent to be made an addition in paper pulp and is called plasm-glue-blending, plasm-glue-blending refers to paper pulp, paper, cardboard is processed, the chemicals of obtaining the performance of anti-current body infiltration and adding, this class chemicals has hydrophilic radical and hydrophobic grouping, at fiber surface, make the outside be orientated hydrophobic grouping, make paper hydrophobic property and anti-current body permeability, on paper, applying glue can improve the paper water resistant, anti-oil, the performances such as anti-printing-ink, can improve slickness simultaneously, hydrophobicity, printing adaptability, internal sizing agent roughly is divided into rosin sizing agent, synthetic sizing agent, paraffin wax sizing agent and neutral sizing agent etc., another kind is after paper sheet formation, to cover with paint, lacquer, colour wash, etc. in the Paper or cardboard surface to be called top sizing, and Cypres is generally used the anionic polymer substance, and major function is to improve the page surface flatness, reduces porosity, prevents wildness and falls hair.Rosin is a kind of traditional internal sizing agent, there is using method simple, cheap, but its environment for use is acid, corrosion to equipment is stronger, therefore, make up with the modified product of gum rosin the shortcoming of gum rosin, these modified rosin glue results of use are better than rosin, and little to equipment corrosion, modified rosin glue again will be better with addition of certain auxiliary material effect.It is raw material that product of the present invention be take modified rosin resin, paraffin, oxidic polyethylene, emulsifying agent, rosinate, macromolecule dispersing agent PEG4000, organic bromine bactericide, stearic acid, colophony type surfactant, take agitator tank as equipment, produce modified rosin sizing agent, there is the series of advantages such as technique is simple, cost is low, good product quality, product is as internal sizing agent, to make an addition in paper pulp when making beating or batching, can effectively improve the performances such as paper water resistant, anti-oil, anti-printing-ink, can improve slickness, hydrophobicity, printing adaptability simultaneously.
Summary of the invention:
The problem to be solved in the present invention is to provide a kind of production method of modified rosin sizing agent, the method is with modified rosin resin, paraffin, oxidic polyethylene, emulsifying agent, rosinate, macromolecule dispersing agent PEG4000, the organic bromine bactericide, stearic acid, the colophony type surfactant is raw material, take agitator tank as equipment, produce modified rosin sizing agent, there is technique simple, cost is low, the series of advantages such as good product quality, the raw material proportioning that the present invention uses is: modified rosin resin 51%-53%, paraffin 10%-12%, oxidic polyethylene 4%, emulsifying agent 21%, rosinate 2%, macromolecule dispersing agent PEG4000 2%, organic bromine bactericide 1%, stearic acid 6%, colophony type surfactant 1%, water is appropriate.
The present invention can be achieved through the following technical solutions:
A kind of production method of modified rosin sizing agent, its feature consists of following steps:
(1) modified rosin resin of formula ratio, paraffin are sent into to agitator tank, first mixing heats up afterwards make abietic resin reach molten condition after, starting agitator stirs, rotating speed is 30 rev/mins, liquid modified rosin resin, paraffin are mixed, then the oxidic polyethylene that adds formula ratio, temperature regulating to 68 ℃-72 ℃, stirring reaction 2 hours.
(2) reaction finishes to continue to be warming up to 93 ℃-97 ℃, the emulsifying agent of formula ratio, rosinate, macromolecule dispersing agent PEG4000, organic bromine bactericide is added to stirring reaction 4 hours.
(3) stearic acid of formula ratio, colophony type surfactant are added and continue to stir, when solution becomes white, rotating speed is brought up to 200 rev/mins, add appropriate water, be cooled to while stirring normal temperature, after stop stirring, obtain the modified rosin sizing agent finished product.
(4) while using, modified rosin sizing agent is made an addition in paper pulp and gets final product when pulling an oar or prepare burden.
The described normal temperature of step (3) is 1 ℃-38 ℃.
The invention has the beneficial effects as follows: a kind of production method of modified rosin sizing agent is provided, and the method technique is simple, efficiency is high, and the sizing agent emulsion stability made is good, good dispersion, sizing efficiency are good; Product, as internal sizing agent, makes an addition in paper pulp when making beating or batching, can effectively improve the performances such as paper water resistant, anti-oil, anti-printing-ink, can improve slickness, hydrophobicity, printing adaptability simultaneously.
