Abstract
Disclosed is a hydrophilic buffing oil with core-shell structure,with its component and mass content: base materials 48-5%, latex 1-3%,water 43-48%, thickener 2-4% and assistant 0.1-0.5%. Coat the hydrophilic buffing oil on printed matter,then buffing it under rolling of 150kg in 80-100deg.C, making the wear resistance and ornamental higher,with protection to water and increased additional value;meanwhile, it uses latex polymerization method,inwhich there is no solvent,remarkably advancing productive condition,it has notably social benefit.
Description
Technical field
The present invention relates to a kind of buffing oil.
Background technology
Buffing oil can give printed matter good mirror effect, increases its wear resistance and glossiness.Buffing oil requires at room temperature can film forming, and therefore roll banding not during polishing, must possess good hardness, wear resistance and good low-temperature film-forming properties simultaneously under 80～100 ℃, 150kg roll-in.Traditional buffing oil is by having added a large amount of organic solvents to reduce its minimum film-forming temperature in hard emulsion, this buffing oil over-all properties is better, but execution conditions are abominable, and environment has also been caused pollution.Therefore, more be to adopt hard emulsion and the composite mode of soft emulsion in recent years, soft emulsion provides film-forming properties, and hard emulsion is given higher hardness of polymeric film and wear resistance.The shortcoming of this mode is that the glossiness of composite emulsion is not so good as the good of single emulsion.Seek out reasonable glossiness, it is similar that the optical index of two kinds of emulsion polymers is wanted, and the particle diameter of the latex particle of hard emulsion is littler than the soft emulsion.
Summary of the invention
The object of the present invention is to provide a kind of aqueous buffing oil of nucleocapsid structure, this aqueous buffing oil strong adhesion, good, the smooth property of wear resistance is good, heat-resisting, water-fast, ageing-resistant performance is good, can give printed matter good mirror effect.
The aqueous buffing oil of a kind of nucleocapsid structure provided by the invention, its component and weight content are:
Base-material 48～50%
Wax emulsion 1～3%
Water 43～48%
Thickening material 2～4%
Auxiliary agent 0.1～0.5%.
Base-material is the benzene emulsion or the pure-acrylic emulsion of nucleocapsid structure in the said components; The wax emulsion is polythene wax emulsion, carnauba wax emulsion or Vaseline emulsion; Thickening material is polyacrylic acid sodium water solution, sodium cellulose glycolate or polyvinyl alcohol; Auxiliary agent is defoamer, sanitas or mould inhibitor.
Base-material is the benzene emulsion or the pure-acrylic emulsion of nucleocapsid structure in the said components, and this base-material method as follows prepares:
(1) add entry and ammoniacal liquor in there-necked flask, high-speed stirring also is warming up to 50～70 ℃, adds the low molecular weight propylene acid resin in batches, is warming up to 75～85 ℃ again, is incubated 1.5～2 hours, obtains acrylic resin soln;
(2) add the mixing solutions of entry and sodium lauryl sulphate in the acrylic resin soln, begin logical nitrogen, stirred 10～30 minutes;
(3) in above-mentioned solution, add potassium persulfate solution, slow then drip styrene monomer, the dropping time was controlled at 1.5～2 hours, dropwised back insulation 15～30 minutes, obtained the white translucent seed emulsion with blue light;
(4) continue drip styrene, butyl acrylate, acrylic acid mix monomer in seed emulsion, the dropping time was controlled at 3～4 hours, in this process, added one time persulfate aqueous solution every 1.5～2 hours, after dropwising, was incubated 1～1.5 hour;
(5) be warming up to 90～95 ℃ of slakings 20～40 minutes again, be cooled to 40～60 ℃ then, add ammoniacal liquor and be neutralized to pH=8, make base-material.
In the aqueous buffing oil of the present invention, the benzene emulsion of the preferred nucleocapsid structure of base-material.The shell second-order transition temperature of this emulsion is lower, has good film formation at low temp to guarantee latex particle; The second-order transition temperature of stratum nucleare is higher, is embedded in during film forming in the external phase of shell, is similar to physical crosslinking, has given polymeric film higher intensity and wear resistance.The said products has solved the conventional emulsion product and has been difficult to satisfy simultaneously low film formation temperature and high-intensity contradiction.Consider that from gloss and cost benzene emulsion is better than pure-acrylic emulsion.
Optimization polypropylene of the present invention acid sodium is thickening material, because with respect to other thickening material, sodium polyacrylate has optimal thickening effectiveness to the emulsion of this nucleocapsid structure.The wax emulsion preferably polyethylene wax emulsion of adding, this emulsion can improve the wear resistance of polymkeric substance, but addition too much can influence the film formation at low temp of emulsion, and be full of cracks can appear in the surface during room temperature film-forming.
Aqueous buffing oil of the present invention at room temperature is coated on printed matter surface, again at 80～100 ℃, after the 150kg roll-in is polished down, have advantages such as strong adhesion, good, the smooth property of wear resistance is good, heat-resisting, water-fast, ageing-resistant performance is good, can give printed matter good mirror effect, increase its wear resistance and glossiness, improve added value, and can significantly improve and produce and execution conditions, have obvious social.
The present invention is further illustrated below in conjunction with embodiment.
