Application of the jelly in papermaking is more and more extensive.It includes the homopolymer and copolymer of acrylic ester monomer.For producing third
The monomer of olefine acid ester polymer can be divided into soft monomer, hard monomer and function monomer three classes.Glass transition temperature is lower(Methyl)
Alkyl acrylate is common soft monomer, it has softness, good fluidity, adhesion strength high and is easy to soak sticker surface etc.
Feature.But since cohesive performance is undesirable, polymer prepared by when exclusive use is too soft to influence practical application performance.Therefore,
People are generally copolymerized using the higher hard monomer of glass transition temperature and soft monomer to adjust the glass transition temperature of polymer, and raising makes
With temperature, improve hydrophobicity, adhesive strength and the transparency.In the molecule of function monomer containing carboxyl, epoxy group, hydroxyl, amido,
The functional groups such as amide groups can adjust the polarity of polymerizate, and can form crosslinking polymer, realize the work(of polymer
Energyization.Due to acrylate polymer have excellent weatherability, film forming and caking property, molecular structure can as needed into
Row adjustment, and multiple functions monomer can be added, polymer is made to have special function, it can significantly improve the property of paper
Can, become the research hotspot of domestic and foreign scholars.Someone has synthesized the cationic crosslinked polymerization containing epoxy and quaternary ammonium group
Object Cypres have studied influence of the factors such as monomeric species and dosage, initiator type to top sizing effect.Grind the hair that makes internal disorder or usurp
The film forming of existing surface size can significantly improve paper performance.Azodiisobutyronitrile is to be suitable for preparing efficient surface sizing agent
Initiator.
Fu little Long etc. is connect using the method for emulsifier-free emulsion polymerization on cationic starch molecule using Fenton reagent as initiator
Branch styrene-acrylic monomer, has synthesized a kind of St/ba Soap-free Emulsion Cypres.The emulsion particle diameter narrow distribution of synthesis, film forming
Property is preferable.When Cypres dosage is 0.4%, the ring crush index and degree of sizing of paper significantly improve.Somebody is with benzene second
Alkene, butyl acrylate, acrylamide, MethacryloyloxyethylTrimethyl Trimethyl Ammonium Chloride and vinyl silane triisopropoxide are original
Material, cation type organic silicon acrylic acid ester emulsion Cypres are prepared for by semi-continuous emulsion polymerizing method.The lotion has
There is excellent stability, can significantly improve the hydrophobicity and mechanical performance of corrugated paper.It is glued body with pure anion tapioca
System compares, and is applied using what 0.4% cation type organic silicon acrylic acid ester emulsion and 99.6% anion tapioca formed
Colloid system handling of paper can make its Cobb value decline 40%, and ring crush index increases by 20%.Zhang Guanghua etc. is good using compatibility
Vinyl monomer dissolving recycling waste polystyrene foam material, be prepared for the no-solvent type Cypres haveing excellent performance,
This Cypres can make the top sizing degree of paper improve 17 times, and ring crush intensity improves 21%, and deflection improves 33%.
In emulsion polymerization systems using reactive emulsifier partly or entirely replace conventional emulsifier method be in recent years
Come a kind of New Emulsion polymerization to grow up.The method avoids the residuals of emulsifier, reduce whole system
Foaming characteristic improves the caking property, hydrophobicity and lustrous surface of film convenient for preparing pure polymer.Recent year
Outer scholar attaches great importance to the exploitation of maleic anhydride type reactive emulsifier.The emulsifier of the type both has efficient emulsifying power
Power, and being copolymerized with monomer, emulsion particle particle diameter distribution is narrow, can prepare the lotion of high solids content, and polymer is answered
It is also obviously improved with performance.
