Description
Technical field
The present invention relates to degasser, be specifically related to the water-soluble higher alcohols degasser of a kind of copy paper.
Background technology
In papermaking operation, the existence of foam can affect the quality of paper delivery and the operational efficiency of machine greatly.In general, the reason causing foam to occur has two.One is can add many auxiliary agents with surface active function before slurrying and copy paper are surfed the Net, as digestant, washing agent, retention agent, filter aid, wet strength agent, sizing agent etc., the lignin, starch catabolin, resin etc. that itself contain in slurrying simultaneously also can serve as the role of stabilizing agent, reduce the interface energy of liquid level and air, easily bubble.Two is that the mechanical processes such as wet end dehydration, labial lamina whitewashing, pumping procedure, stock tank stirring all can introduce a large amount of air to wet pulp, becomes the main cause of foaming.Air content high in addition also can cause into pinprick, the porosity increase of paper, and makes the drainage of paper machine reduce, increase pumping energy consumption.Therefore use degasser in the copy paper stage, effectively reduce the air content in paper pulp, seem particularly important.The action principle of degasser is stripped out by absorption air minute bubbles in the fibre, pools air pocket and to emerge liquid level, finally break.
In the market and copy paper degasser disclosed in patent be generally oil-in-water type higher alcohols degasser, with higher alcohols and derivative thereof for main active, emulsification type is Water-In-Oil.Corresponding patent has US430359, US4976888, US5679286, US5866041, US6649721, EP0149812, EP0531713, CA02493055, US3673105, US3923683, DE-A2944604, CN1538866A, CN1781574, US5679286, EP-A513173, EP-A662172, DE-A4232415, CN101718055A etc.But emulsion is thermodynamically non-stability system, the phenomenons such as the long easy appearance reunion of oil-in-water type higher alcohols degasser period of storage, gel, thickening, affect result of use.The degasifying effect of warm oil-in-water type higher alcohols degasser can die down along with increasing of temperature in addition, carrys out reinforcement often through increase consumption.Meanwhile, emulsifying temperature is often up to 90-100
oc, increases preparation process difficulty.
Summary of the invention
The object of the invention is to: provide a kind of copy paper water-soluble higher alcohols degasser, this degasser possesses all advantages of emulsion-type higher alcohols degasser, service condition is gentle, has wide spectrum applicability.
Technical solution of the present invention is: count it by weight and comprise following component: the degassed active material of 60-90 part, 0.1-25 part weak anionic surfactant, 9.9-15-part dispersant.

oc initiated polymerization obtains for 1-3 hour, and molecular weight is at 500-1000000, and its general structure is as follows:
，
Wherein R is the 1-3 unit alcohol of 8-24 carbon atom, and m, n are the number contained in a molecule, and m is 1-5000, n is 0-2000.
Wherein, Long Chain Alkyl Acrylate is obtained by esterification by least one in the 1-3 unit alcohol of acrylic acid and 8-24 carbon atom.
Wherein, initator is redox initiator or radiation initiators or thermal initiator.
Wherein, higher alcohols are at least one in the 1-3 unit alcohol of 8-24 carbon atom.
Wherein, fatty acid ester is obtained by esterification by the 1-3 unit alcohol of the aliphatic acid of 8-16 carbon atom and 3-24 carbon atom.
Wherein, weak anionic surfactant is at least one of 10 two to octadecyl carboxylates.
Wherein, dispersant is at least one of the stearmide of 16-36 carbon atom, polyoxyethylene alkane ether, polyoxyethylene polyols ether, polyoxyethylene polyoxypropylene block copolymer.
Beneficial effect of the present invention is:
