A kind of heat-resistance type printing paper product water lustering oil and preparation method thereof
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of heat-resistance type printing paper product water lustering oil and preparation method thereof.
Background technology
Printing gloss oil is claimed finishing oil or glazing paint again, is a kind of printing coating material.At present the oil polish of use mainly contains three kinds on solvent-borne type, UV light-cured type and water-based type in the printing of papery article.The solvent-borne type oil polish has advantages such as good anti-solvent, chemicals-resistant, high gloss, but can volatilize a large amount of organic solvents in use, thereby influences the healthy of people, and serious environment pollution is progressively eliminated; UV light-cured type oil polish has that rate of drying is fast, and advantages such as chemicals-resistant, high gloss, but complex process cost an arm and a leg, thereby large tracts of land is promoted and received certain limitation; Water lustering oil is the novel environment-friendly product that grows up the nineties in 20th century, and it has strong, colourless, tasteless, nontoxic, low-cost, and the advantages such as good glossiness, folding resistance of transparent feel, thereby becomes the main at present kind of using.
Printing paper product glazing divides common glazing, online glazing and preprints several kinds of glazings.Wherein preprint only corrugated case and preprint the step of one in production special process.The characteristics that corrugated case is preprinted production are in advance the facial tissue of corrugated case to be printed, then directly and corrugated paper carry out the mount pressing, and then be die-cut to case.The facial tissue that prints needs through the elevated temperature heat pressure roller when carrying out the mount pressing with corrugated paper, and temperature is about 160-220 ℃, and therefore the heat resistance to employed glazing paint has proposed higher requirement.
Water lustering oil is mainly polyacrylate dispersion, and polyacrylate has good filming performance, transparent, the pliable and tough and high resilience of the film of formation; But because its structure is generally the chain linear structure; Belong to thermoplastics type's material, very responsive to temperature, the phenomenon of " hot sticky cold crisp " can appear.Organosilicon-modified acrylate class emulsion has been because of having introduced the Si-O key that bond energy is big, strand is submissive, can effectively improve resistant of high or low temperature, resistance to water, hardness of polyacrylate etc.The organosilicon-modified acrylate emulsion polymerization is divided into two kinds of emulsion dispersion and emulsion copolymerization methods according to method of modifying.When emulsion dispersion prepares organosilicon-modified acrylate emulsion; Be earlier organic silicon emulsion to be mixed with stabilizing agent; Mix according to a certain percentage with acrylic acid ester emulsion again after regulating pH value, but the organosilicon-modified acrylate emulsion less stable of this blending and modifying, be easy to generate two be separated, the storage life lacks; And not having chemical bond to combine between organosilicon polymer and acrylate polymer, the raising of its weatherability and adhesive force is also not obvious.It is that organosiloxane that has active group (carbon-to-carbon double bond etc.) and acrylic ester monomer are carried out copolymerization that the emulsion copolymerization legal system is equipped with the organosilicon-modified acrylate emulsion; Generate emulsion polymers such as random, grafting, block or interpenetrating networks; Thereby obtain stable organosilicon-modified acrylate emulsion system, and improve polymer-modified performance greatly.
The present invention carries out emulsion copolymerization with the organic silicon monomer of acrylate monomer and carbon-carbon double key, the preparation organosilicon-modified acrylate emulsion.With it is that film forming agent and water soluble amino resin, wax emulsion, levelling agent, antifoaming agent etc. are re-dubbed the brightening water-based oil for printing with good heat resistance.
Summary of the invention
To the deficiency that exists in the prior art; The object of the present invention is to provide a kind of heat-resistance type printing paper product water lustering oil and preparation method thereof; Can not resistant to elevated temperatures defective thereby overcome common acrylic acid ester oil polish, introduce the waterproof and dampproof ability that functional organic silicon monomer can also reinforcing membrane simultaneously.
