Abstract
The present invention relates to modified paraffin wax for printing wax, which aims at providing wax with abundant resources, good quality and low cost for printing ink. Paraffin wax and wax with a high melting point are used as raw materials of the modified paraffin wax, and the modified paraffin wax is formed by leading air into the raw materials for oxidation under the action of a catalyst and a cocatalyst. The modified paraffin wax has the advantages of sufficient raw materials, simple and feasible technology, safe and convenient operation, low product cost and stable quality. The physical and chemical performance indices of the present invention reach or are better than those of natural beeswax. Printing ink products formed by the present invention reach a printing ink product standard ZBA17004-87 issued by the ministry. The present invention can completely replace natural beeswax to be used in printing ink.
Description
The present invention relates to a kind of printing-ink wax, particularly relate to a kind of paraffin modification technology.
In printing-ink, to control its serviceability, drying property and improve with wax and anti-ly wipe the foam performance for a long time, animal wax and vegetable wax are used the earliest in this respect, and beeswax, little candle wax, carnauba wax and Japan tallow also using so far.At present, all use natural beeswax in most of printing-inks, beeswax can improve the lifting performance of cover color ink, prevents wriggling.But the beeswax shortage of resources, price height, and contain moisture content uses dangerously, does not satisfy the requirement of printing ink industry.As for carnauba wax and Japan tallow, need cost an arm and a leg from external import.Obtain the cheap paraffin of price comparison and also once be used in the printing ink from refining of petroleum, but unmodified single paraffin is dissolved in the clear vehicle of stone of usefulness such as common type printing and lithographic printing ink hardly, the ink pellet surface of making just forms granular epidermis soon.
The object of the present invention is to provide the modified paraffin of a kind of wax aboundresources, super quality and competitive price, substitute natural beeswax.
The object of the present invention is achieved like this: the printing ink modified paraffin is to be raw material with paraffin, high melting-point wax, and under catalyzer, promotor effect, the bubbling air oxidation forms.By ratio of weight and the number of copies, paraffin: high melting-point wax: catalyzer: promotor=1: 0.11-1.50: 0.0011-0.005: 0.011-0.200.
66-90 ℃ of paraffin melting point 58-64 ℃, high melting-point wax fusing point.Catalyzer is a potassium permanganate, and content is greater than 90%, and promotor is ten dihydroxystearic acids, acid number 172-183mgKOH/g, and hydroxyl value is less than 130mgKOH/g.The condition of oxidizing reaction is oxidizing temperature 120-160 ℃, air capacity 0.11-1.0m
3/ h.kg.
Printing ink modified paraffin of the present invention, be in the wax molecule, to introduce to contain dioxygenase gene, strengthened the wax molecular polarity, make its emulsifying property good, stronger avidity and surfactivity are arranged, easier and chromatophore dissolve each other, and make the physical and chemical indexs such as fusing point, acid number of modified paraffin reach natural beeswax index, can replace natural beeswax to use in printing ink fully.The printing ink that this modified paraffin is made reaches ink product ministerial standard ZBA17004-87, and outward appearance is than natural bee wax product exquisiteness Paint Gloss, steady quality.And natural beeswax contains moisture content, must be heated 120-130 ℃ before using and deviate from moisture, otherwise can overflow during refining pot, the foam that rises can catch fire when serious, and is very dangerous.And modified paraffin water content not can directly use, and has characteristics such as simple for process, safe and convenient to use.The modified paraffin raw material sources are abundant, and the paraffin refinery all has production, and cheap.Natural beeswax shortage of resources costs an arm and a leg.The modified paraffin production cost is low, 1.5 ten thousand yuan per ton of product price, and than ten thousand yuan of sky beeswax reduction per ton 0.3-0.5, economic benefit is more remarkable, and replacing natural beeswax technology with modified paraffin serves as that development China paraffin chemical industry has been opened up a new way.
The invention will be further described below in conjunction with embodiment:
Embodiment 1: to make 1 kilogram of printing ink modified paraffin is example, with paraffin (62.4 ℃ of fusing points) 900 grams, and high melting-point wax (75 ℃ of fusing points) 100 grams, ten dihydroxystearic acids (acid number 172mgKOH/g), 30 grams add in the white head tower heat temperature raising together, after the raw material fusing, in tower, feed 0.15m
3/ h.kg air continues to heat up, and when temperature reaches 120 ℃, slowly adds potassium permanganate (content 90%) 1.5 grams, carries out oxidizing reaction, after 4 hours, and sampling analysis, when acid number reached 16-22mgKOH/g, stopped reaction made 1 kilogram of printing ink modified paraffin.Product appearance: block, light yellow, 61.9 ℃ of fusing points, acid number 16.86mgKOH/g, moisture content do not have.Reach natural bee wax product quality index: outward appearance: block, yellow, fusing point 61-65 ℃, acid number 16-22mgKOH/g, moisture content 1-2%.This modified paraffin send Shenyang City printing ink factory to do industrial application test, replaces the natural beeswax of same ratio in the proportioning respectively with the printing ink modified paraffin, makes and spreads light dose, slimicide, in-20 ℃ of refrigerator-freezers freezing 72 hours, does not have any variation.This wax slimicide sample is more finer and smoother than beeswax slimicide, constant product quality.Synthetic ink product by analysis, quality index is as follows: set time 40min, fineness 15 μ m, conjunctiva time 8h, viscosity 14, mobile 38mm, increasing value of tack 4 reach ink product ministerial standard ZBA17004-87.
Embodiment 2: with paraffin (60.2 ℃ of fusing points) 400 grams, and high melting-point wax (80 ℃ of fusing points) 600 grams, ten dihydroxystearic acids (acid number 180mgKOH/g), 10 grams add in the white head tower together, and heat temperature raising after the raw material fusing, feeds 1.0m in tower
3/ h.kg air continues to heat up, and when temperature reaches 130 ℃, slowly adds potassium permanganate (content 90%) 1.8 grams, carries out oxidizing reaction, after 4 hours, and sampling analysis, when acid number reached 16-22mgKOH/g, stopped reaction made 1 kilogram of printing ink modified paraffin.Product appearance: 62 ℃ of block, light yellow, fusing points, acid number 17.2mgKOH/g, moisture content do not have.This modified paraffin send Shenyang City printing ink factory to do industrial application test, the natural beeswax that replaces same ratio in the proportioning with modified paraffin respectively, synthetic printing ink, the product analysis quality index is as follows: set time 40min, fineness 15 μ m, conjunctiva time 8h, viscosity 14, mobile 38mm, increasing value of tack 4.Reach ink product ministerial standard ZBA17004-87.
