The cation dispersed colophony surface sizing agent has good emulsification effect, latex retention rate and paper water resisting property after paper gluing are both greatly improved, the sizing agent does not generate pollution, and the neutral-alkaline sizing agent does not have corrosion to the equipment, thus reducing the production cost of paper making. The sizing agent has reasonable formula, simple process and stable performance.
Description
Technical field
The present invention relates to a kind of macromolecular material, specifically a kind of improved cation dispersed common resin surface sizing agent.
Background technology
We know, sizing agent is to add in paper pulp or at some WATER RESISTANCE materials of paper surface coating, it can postpone fluid permeability, gives the performance of the anti-water of paper, anti-oil.Sizing agent can be divided into acid accumulator size and neutral and alkali sizing agent by the applying glue environment, and the neutral and alkali sizing agent is compared with traditional acid accumulator size has TiO little to equipment corrosion, that pollutional load is light, the pearl filler of available cheapness replaces costliness
2Etc. plurality of advantages.At home, neutral and alkali sizing agent-cationic dispersion rosin size has caused the attention of more and more producers, but relevant research, development are deep not enough.External AKD (alkyl ketene dimer), ASA (alkenyl succinic anhydride) and the neutral and alkali sizing agent of adopting, AKD exist the curing time long, degree of sizing is wayward, be prone to phenomenon such as skid; ASA also exists emulsion storage life weak point, the on-the-spot emulsification of needs, emulsifying device and operating technology is had drawbacks such as strict demand.Comparatively speaking, cation dispersed common resin has better applicability than AKD and ASA.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of prescription reasonable, stable performance, and technology is simple, the cation dispersed common resin surface sizing agent of the neutral and alkali that cost is low.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of cation dispersed common resin surface sizing agent, it mainly is made up of rosin and compound surfactant, compound surfactant comprises colophony type surfactant, macromolecule cation dispersant, surface of base activating agent, it is characterized in that: per 100 weight portion rosin add compound surfactant 65-75 part in the compositing formula, and colophony type surfactant, macromolecule cation dispersant, surface of base activating agent are formed by weight 0～0.2:2.5～3.5:0.5～2.5 in the compound surfactant.
Cation dispersed common resin surface sizing agent emulsify well of the present invention, latex retention and paper WATER RESISTANCE all improve a lot behind the paper sizing, and because of being raw material with rosin, sizing agent is pollution-free, the neutral and alkali sizing agent does not have corrosion to equipment, has reduced the paper cost.The present invention fills a prescription rationally, and technology is simple, stable performance.
The specific embodiment
The invention will be further described below in conjunction with embodiment:
A kind of cation dispersed common resin surface sizing agent, it mainly is made up of rosin and compound surfactant, compound surfactant comprises colophony type surfactant, macromolecule cation dispersant, surface of base activating agent, per 100 weight portion rosin add compound surfactant 65-75 part in the compositing formula, and colophony type surfactant, macromolecule cation dispersant, surface of base activating agent are formed by weight 0～0.2:2.5～3.5:0.5～2.5 in the compound surfactant.
The constituent of colophony type surfactant of the present invention: rosin: NaOH: epoxychloropropane: triethylamine=1:1:2:2, isopropyl alcohol (60ml).Each composition effect is: epoxychloropropane and sodium abietate reaction form intermediate; Triethylamine plays quaternarization; Isopropyl alcohol plays the dicyandiamide solution effect.
The building-up process of colophony type surfactant is: take by weighing in rosin and the three mouthfuls of conical flasks, add isopropyl alcohol, heating, stir, treat to add NaOH again after the complete fusion of rosin, adjust 80 ℃ of temperature, constant temperature 6 hours slowly adds epoxychloropropane, reaction condition is 95 ℃, 12 hours, the adding triethylamine carried out quaternary ammoniated, and reaction condition is 60 ℃, after question response finished in 10 hours with product revolve steam to remove and desolvate, can obtain the colophony type surfactant.
Macromolecule cation dispersant constituent of the present invention: isopropyl alcohol and water are made solvent, isopropyl alcohol in the 250ml four-hole boiling flask: water=2:1, add 0.05mol styrene, add the 0.15mol methyl acrylate, epoxychloropropane is a small amount of, add 0.25mol dimethylaminoethyl acrylate methyl ammonia ethyl ester, a small amount of persulfate.Wherein persulfate plays initator effect and above-mentioned constituent reaction formation copolymer.
In the 250ml four-hole boiling flask, add isopropyl alcohol and water and make solvent, add styrene, methyl acrylate, methyl methacrylate ammonia ethyl ester, nitrogen protection is stirred, is mixed down, establishes 60 ℃ of temperature, drips initator, heats up 80 ℃ then, reacts 5 hours.Drip epoxychloropropane, the reaction 2 hours down of 80 ℃ of reaction temperatures, after the isopropyl alcohol in the products therefrom is removed, promptly obtain the aqueous solution of macromolecule cation dispersant.
Cation dispersed common resin surface sizing agent of the present invention is formed: rosin: colophony type surfactant: macromolecule cation dispersant: surface of base activating agent (bromododecane base dimethyl benzyl ammonium)=10:0.15～0.29:3.5～6:0.7～3.6 (be fixed as 10 with rosin, regulate other reagent qualities ratios).Rosin can be made into Cypres after emulsified in the constituent.
In 100ml single port flask, add rosin in 90 ℃ of following fusions, then colophony type surfactant, macromolecule cation dispersant and basic cationic surfactant (bromododecane base dimethyl benzyl ammonium) synthetic in the above-mentioned experiment are added in proportion, mixed melting 9-11s, after stirring at low speed 28-35 minute, add the phase inversion water of preheating, carry out phase inversion under stirring fast, finishing, the back is rapid cools off, and obtains composite cation dispersion Cypres.
The present invention is fixed as 10 with rosin, regulates other reagent quality ratios.Compound surfactant comprises colophony type surfactant, macromolecule cation dispersant, surface of base activating agent.Concrete experiment and emulsifying effectiveness are:
Composite cation dispersion Cypres emulsifying effectiveness is fine, and latex retention and paper WATER RESISTANCE all improve a lot behind the paper sizing, and because of being raw material with rosin, sizing agent is pollution-free, and the neutral and alkali sizing agent does not have corrosion to equipment, has reduced the paper cost.
