In the invention, after the high alcohol polyether ester is introduced, the problem that the antifoaming effect of the high alcohol emulsion is poor under a low temperature condition is solved, thus the high alcohol emulsion can keep outstanding antifoaming performance under the low temperature paper making system, and the storage stability of the high alcohol emulsion can also be enhanced.
Description
Technical field
The present invention relates to a kind of paper industry and copy paper system defoamer, be under the jurisdiction of technical field of fine chemical preparations.
Technical background
Paper industry comprises slurrying, copies operations such as paper and coating.Because various influences in the wet end chemistry with surface-active auxiliary agent, be easy in water, produce the foam of a large amount of difficult eliminations, simultaneously, contained various string hydroxyls in the pulping raw material, be easy to make fiber surface and inner absorption to be difficult to remove the tiny bubble foam with common defoamer in a large number, have a strong impact on the quality of subsequent handling and product, therefore, the selection of defoamer and use, particularly important for machine hand's preface.
The main effect of copying the paper defoamer is that the bubble that will be adsorbed on the fiber fines is earlier peeled away, and makes minute bubbles gather into bulla then and floats on the liquid level, and the bubble vacuolar membrane attenuation on the last water surface is finally broken.The paper of copying of existing better performances is generally the higher alcohols emulsion defoamer with defoamer, is main active with higher alcohols, forms emulsion oil-in-water by emulsifying process.For example, US4976888 discloses a kind of higher alcohols emulsion defoamer of being made up of higher alcohols, high-carbon alcohol ester, high boiling aliphatic hydrocarbon, Tissuemat E and emulsifying agent; US5679286 discloses a kind of higher alcohols emulsion defoamer of being made up of higher alcohols, letones and emulsifying agent; US430359 discloses a kind of higher alcohols emulsion defoamer of being made up of higher alcohols, aliphatic acid and saponified emulsifier; EP0149812 discloses a kind of higher alcohols emulsion defoamer of being made up of higher alcohols, high-carbon alcohol ester, higher boiling aliphatic hydrocarbon, water-soluble acrylic (acrylamide) polymer and emulsifying agent; CA02493055 discloses a kind of higher alcohols emulsion defoamer of being made up of higher alcohols, polyglycereol stearate, mineral oil, the two stearic amides of ethylenediamine, fatty acid ester and emulsifying agent.
Although the present paper technology of copying constantly promotes, the water temperature of plain boiled water is also on the rise, but because China is vast in territory, north-south climate differs greatly, cause in the winter time under the environment, the water temperature when paper is copied by part enterprise is on the low side, existing higher alcohols emulsion defoamer, therefore can not adapt to the foaming system under the low temperature, disappear and press down the bubble ability and become relatively poor.Simultaneously because emulsion is astable system on thermodynamics, the higher alcohols emulsion defoamer through long term storage or more possible be to occur easily after the long term storage under the low temperature being separated, thereby influence the use of defoamer.
The inventor by to wherein adding the higher alcohols polyether ester, can effectively solve the problem of the froth breaking variation of higher alcohols emulsion under cryogenic conditions through a large amount of experimental study and The field, has also strengthened the storage stability of higher alcohols emulsions simultaneously.
Summary of the invention
The objective of the invention is: provide a kind of under cryogenic conditions the good higher alcohols emulsion-type of antifoam performance copy the paper defoamer, its bin stability is good, the preparation condition gentleness.
Low temperature of the present invention is copied the paper system and is grouped into by following several one-tenth with defoamer:
