Description
Technical field
The present invention relates to a kind of higher alcohols defoamer.Higher alcohols defoamer is mainly used in paper industry, is mainly used in
Copy paper system.Defoamer belongs to fine chemical product, therefore the invention belongs to technical field of fine.
Background technology
Paper industry is divided into slurrying, papermaking and three parts of coating.Method many employings chemical method of slurrying, will timber,
The raw material such as bamboo, grass shred, through steaming and decocting, pulp washing, screen, bleach, pull an oar and prepare paper pulp.In raw material organic rich in many hydroxy acids
Thing, it is easy to make plant fibre surface and the most tiny bubble being difficult to eliminate of internal absorption；It addition, add in digestion process
Digestant, the retention agent increasing considerably and adding therewith of speed, filter aid, sizing agent, wet strength agent in paper-making process
Deng, these additive main bodys are macromolecular compounds, and they can play steady bubble or the effect bubbled in water so that vacuolar membrane
Intensity enhancing, thus considerably increase the difficulty of froth breaking.During whole slurrying with papermaking, except raw material chopping and paper are done
Beyond dry two-step, foam has harm in various degree to remaining each operation, speckle, diaphanous spot, aperture such as occurs, even
It is disconnected paper etc., causes great industrial loss.Therefore, use defoamer, particularly important for whole paper industry.
Copy paper system paper motor speed quickly, and adds kinds of surface activating agent, it requires that defoamer not only to have good
Good degassing suds suppressing properties, to have good dispersibility simultaneously.Although organic silicon defoamer froth breaking suds suppressing properties is good, but to emulsifying
Technological requirement is the highest, and once emulsifying is bad, and silicon speckle will be stayed on paper to cause industrial loss.Low-carbon (LC) alcohol defoaming agent has
Certain defoaming effect, but suds effect is poor.
A lot of document is had to describe the application in copy paper system of the higher aliphatic alcohols defoamer, such as patent CN
102337706 A describe a kind of defoamer emulsion being made up of C18-C20 alcohol and emulsifying agent, and patent CN102242523A is introduced
There is the defoamer emulsion that high fatty alcohol, higher alcohols polyether ester and emulsifying agent, thickening agent are made, for coating and copy paper plain boiled water
System.But after adding defoamer soon, its defoaming effect declines, and embodies suds ability the best.
Patent US 2013303635 discloses the defoamer emulsion of O/W type, and its main component includes, at least containing 16 carbon
The fatty alcohol (preferably 16-20 carbon atom) of atom, fatty acid ester (it is made up with polyglycereol of the higher fatty acids of C12-36,
Or the high fatty alcohol of the higher fatty acids of C12-36 and C12-36 is made), and the liquid state organics that boiling point is higher than 200 DEG C；
Patent EP 0531713 describes a kind of higher aliphatic alcohols emulsion defoamer, and its oil-phase component includes high fatty alcohol, and (carbon is former
Son at least 12), high-grade aliphatic ester (generated by the high fatty alcohol of the higher fatty acids of C1-36 with carbon atom at least 22, or
Person is that C12-22 higher fatty acids is condensed into C1-18 high fatty alcohol, or boiling point is senior higher than the hydrocarbon of 200 DEG C or C12-22
Fatty acid is condensed into polyglycereol), add that bigger hydrophilic emulsifying agent is made；The emulsion that both approaches prepares, stores temperature
Degree less than 20 DEG C, viscosity can passage in time and become big.Because high-grade fatty alcohol emulsion effectively aqueous systems can reduce table
Surface tension, so its content is the most, defoaming effect is the best, but C14 and the fatty alcohol containing more C atoms are solid, shaped, emulsifying
After, along with the reduction of temperature, its aggregation velocity is accelerated the most therewith, and the viscosity of emulsion increasing can even present paste.

Stable fatty alcohol emulsion prepared by face activating agent, but the 1 of C6-18,2 glycol production processes are complicated, expensive, are not suitable for
Industrialized production；Patent CN1781574 uses the adduct of oxirane and secondary alcohol to prepare stable senior fat as emulsifying agent
Fat alcohol emulsion, the but when molecular weight of emulsifying agent is bigger, the emulsion of preparation can very thickness, meanwhile, to the selection of emulsifying agent and compounding
Higher than required precision, compound proportion is high or too low, and emulsion coagulation or antifoam performance all can be caused to weaken.
The present inventor studies discovery, and when the content containing high fatty alcohol, particularly C18 is more, system can generate footpath
The particle that grain is bigger, this granule is very easy to assemble, and generates liquid crystalline phase and causes the viscosity of emulsion to become big, even has crystal to separate out
And form body of paste；So needing more emulsifying agent, but increasing of emulsifying agent, the increase of system foaming capacity can be caused, with
Time cause defoamer solubilized so that losing the effect at surface spreading, froth breaking effect subtracts greatly.The present inventor grinds through substantial amounts of
Study carefully, propose a kind of to prepare the defoamer emulsion that high fatty alcohol content is high, and emulsifying agent usage amount is the highest；I.e. use emulsifying
Agent phase emulsion process, mixes a small amount of anionic surfactant and nonionic surfactant, adds a certain amount of water
And co-emulsifier, form mixed micelle system, thus strengthen its absorbability, greatly strengthen emulsifiability；Simultaneously because of the moon from
The addition of sub-surface activating agent so that high fatty alcohol molecule is difficult to Coulomb repulsion assemble with each other, the most senior fat
The content of fat alcohol can reach more than the 25% of defoamer gross mass；After stirring, the footpath grain of micelle volume is less, then adds remaining
Oil phase and aqueous phase；The selectivity of emulsifying agent and the HLB value of emulsifying agent are not required by this method, and cost of material is relatively low；Prepare
Emulsion all can keep good stability at room temperature and low temperature, has excellent froth breaking suds suppressing properties simultaneously.
