Abstract
The invention discloses an organic fluorine waterproof oilproof finishing agent emulsion and a preparation method thereof. The organic fluorine waterproof oilproof finishing agent is polymerized from impurity-oxygen perfluoro-alkyl (methyl) acrylate monomer used as the principal monomer, and higher fatty alcohol acroleic acid and hydroxyethyl (methyl) acrylate used as the auxiliary monomer. The organic fluorine waterproof oilproof finishing agent emulsion can be used for waterproof and oilproof finishing of paper sheets and paper boards.
Description
Technical field
The invention belongs to paper, paperboard surface finishing field.Relate to a kind of organic fluorine waterproof oil resistant finish agent emulsion and preparation method thereof.
Background technology
Organic fluorine treatment agent product have lower interfacial tension, good thermotolerance and chemical stability, thereby can give the waterproof and the oil preventing performance of base material excellences such as woven fabric, leather, paper and cardboard.
(methyl) acrylic ester high molecular type has good film-forming property, characteristics that the cured article snappiness is good, with its as finishing composition handler woven fabric, paper etc. after, the item for disposal good permeability, good hand feeling is arranged.Though poly-(methyl) acrylate has better waterproof, and raw material is easy to get, cost is low, does not possess oil preventing performance.If fluorochemical monomer with the common polymerization of (methyl) acrylic ester monomer, then can be prepared not only waterproof but also grease proofing surface finishing agent.
Although fluorochemicals has important use in waterproof, aspect grease proofing, fluorochemicals need use a large amount of auxiliary agents usually.This analog assistant be in water and fluorine monomer in the organic solvent of high-dissolvability is all arranged, the use of solvent helps monomer to have monomer droplet to spread in polyalcohol emulsion particle.As U.S. Pat 08/048,350 add acetone as the polymerization used additives when polymerization, Japanese Patent JP309562/1999 proposes water miscible high viscosity auxiliary agent (25 ℃ time viscosity more than 3cP) is added to the water as triethylene glycol, dipropylene glycol dme etc. and forms compound water-medium.But the use of solvent can cause the decline of aqueous dispersion burning-point, perhaps remains in the object being treated, and this is very disadvantageous.No matter use which kind of solvent, all can increase the VOC value (volatile organic matter) of system, unfavorable to environment.And the present invention is a kind of waterproof oil-proof finishing agent emulsion that is used for paper and cardboard, and it is a kind of waterproof oil-proof finishing agent of aqueous dispersion type, does not wherein contain those unwelcome organic solvents.Therefore use not only safety performance height, also very little to the influence of environment.
Because the proportion of (methyl) acrylic ester monomer and fluorochemical monomer differs bigger, when obtaining multipolymer by emulsion polymerization, suspension polymerization etc., be difficult to make above-mentioned two kinds can gather monomer and be dispersed in uniformly in the polymerisation medium, therefore before polymerization, want by the high speed mechanical stirring it is dispersed in the polymerisation medium uniformly earlier.
The present invention is assorted oxygen perfluoroalkyl (methyl) acrylate monomer, high fatty alcohol (methyl) Acrylic Acid Monomer, (methyl) crylic acid hydroxy ester class monomer, the fluorinated copolymer emulsion that letex polymerization obtains in the presence of emulsifying agent, chain-transfer agent, initiator.The present invention has excellent water and oil repellant performance, and emulsion particle diameter is little, and does not wherein contain those unwelcome organic solvents, therefore uses not only safety performance height, and is also very little to the influence of environment.Working method of the present invention is simple simultaneously, and reaction conditions requires simple.Compare not only waterproof oil-proof result with product of the same type good but also cost is low.
