Description

A kind of preparation method of Cypres
Technical field
The present invention relates to a kind of preparation method of Cypres, specifically a kind of system of surface sizing agent for paper making Preparation Method.
Background technology
Top sizing be it is a kind of to paper surface processing to improve the important way of its application performance.It is needed in processing procedure It to be coated with a certain amount of sizing material in the equal sentence of paper surface(General coating weight control is in 0.3~2g/m2Between).At top sizing Reason not only increases the resistant to liquids penetrating power of paper, and can also improve its mechanical strength, surface property and printing performance, together When reduce the dosage of internal sizing agent, alleviate due to the problems such as machinery stains caused by plasm-glue-blending.Cypres Type is divided into three kinds of cationic, anionic and nonionic.Cationic surface-sizing agent can be to the moon of paper fibre Ionic group generates suction-operated, and hydrophobic grouping forms hydrophobic layer after stablizing, so as to improve the performance of paper.Anionic surface Sizing agent using when need additional precipitating reagent to be complexed and be gathered in paper surface, the performance of paper is improved after film forming.
The principal item of Cypres have starch, guar gum, gelatin, cellulose and hemicellulose, shellac, chitin and Alginic acid, gum rosin etc..With the development of petrochemical industry and high polymer synthesis industry, the surface of acrylate polymer series is applied 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.
Chinese patent CN201711098672.0 discloses a kind of Cypres and its preparation method and application, wherein table Surface sizing agent percentage composition by weight includes following raw material components:Bulk composition 20%~40%, hydrophilic resin 3%~15%, Mould inhibitor 2%~12%, ethylene absorbent 1%~6%, auxiliary agent 0.5%~2%, water 50%~70%;The wherein described main body at It is selected from one or more in rosin, gelatin and starch, the ethylene absorbent is the carrier for loading active ingredient, institute It states active constituent and is selected from least one of potassium permanganate, calper calcium peroxide and silver chlorate.The combination of the Cypres and fiber Power is good, and the surface that can be applied to paper forms one layer of fine and close film, and paper is made to have certain water-retaining property.Especially suitable for fruits and vegetables Packaging and fresh-keeping, play the role of bacteria mildew-proof, reduce ethylene concentration in packaging, avoid fruits and vegetables water loss, extend fruits and vegetables Freshness date.Meanwhile the film that densification is formed in paper surface can also improve the toughness and surface strength of paper.
Chinese patent CN201710665792.8 discloses a kind of double corrugated paper Cypres, by the raw material of following number Group is grouped as:25~35 parts of cornstarch, 15~25 parts of purple sweet potato starch, 10~20 parts of sodium sulphate, perfluoro butyl sulfonic acid fluoride 10~ 15 parts, it is 2~18 parts of triethanolamine, 1~5 part of citric acid, 5~15 parts of petroleum sodium sulfonate, 2~4 parts of fatty alcohol polyoxyethylene ether, right 2~4 parts of nitrobenzoic acid, 1~2 part of sodium tetraborate, 2~3 parts of dimethyl maleic anhydride, modified oxidized dose 10~15 parts, go from Sub- water is several, and sizing agent of the present invention of the invention is glittering and translucent, and no foreign pigment, viscosity greatly enhances, stronger than common sizing agent 70-80%.
Chinese patent CN201710630865.X discloses a kind of preparation method of the anti-Cypres that get damp, composition portion It includes 600-700 parts of polyamino resin, 195-215 parts, 135-160 parts glyoxals of styrene-acrylic resin, 70-90 parts of aluminum sulfate, 7-12 to divide 180-195 parts and 650-750 parts part zirconium oxychloride, alkyl Xi ketone dimers water.These types of goods and materials compounding composition it is anti-get damp it is poly- Polyimide resin emulsifier can form highly stable lotion after emulsifying alkyl Xi ketone dimers, after top sizing, in paper The excellent water resistant coating of the quick forming properties in surface, this coating is with little need for curing, and machine is generate 100% anti-under paper Outlet capacity, will not be grown because of the maturation period causes paper to get damp and influences intensity and water resistant ability.
Chinese patent CN201710607175.2 discloses a kind of corrugated paper Cypres and preparation method thereof, the corrugation Paper Cypres include the raw material of following parts by weight:20-35 parts of siloxanes, 50-100 parts of stearic acid, (methyl) acrylate 20-35 parts of class monomer, 60-70 parts of (methyl) styrene, 6-7 parts of cationic monomer, 20-30 parts of dispersant, cross-linking monomer 2-3 Part, 2-3 parts of emulsifier, 0.5-3 parts of initiator, 800-1000 parts of water.It is a large amount of to contain due to the stearic acid used in the present invention The reason of carboxyl can be combined with the carboxyl of fiber surface, improved its bonding force between corrugated paper, improved corrugated paper Ring crush intensity.
