Description
Technical field
The invention belongs to technical field of ink, particularly relate to a kind of environment-friendly type, the tin graphed sheet chalk of resistance to deep draw.
Background technology
Tinplate (being commonly called as tinplate) is still at present one of main raw of packaging industry, and this is because it has high temperature resistant process, mechanical resistant processing and the premium properties such as corrosion-resistant.In order to attractive in appearance and be convenient to identify various content, then need before tank processed on tinplate outer wall prints various pattern and mark.Then need to use Bai Keding, ink, coating etc. according to different packing instructions.Although the resistance to deep draw performance of Bai Keding is far superior to chalk, but Bai Keding is the roller coating printing of full version, just can use under the prerequisite must printed in full version, the printing that this just cannot meet need have and leave a blank on tinplate (namely expose plain sheet or directly printing color pattern etc. on plain sheet), therefore the chalk of printed form occupies certain market share in tin graphed sheet tank industry always.
Existing tin graphed sheet chalk is mainly that binder and the whole toner of titanium dioxide form through mixed grinding by Oleum Cocois Synolac or soybean alkyd, epoxy resin and aminoresin, the wettability of Synolac to pigment is better, sticking power and the snappiness of film are good, and with epoxy resin to improve sticking power, shock-resistant and resistance to steam sterilization performance, aminoresin promotes the crosslinking curing of Synolac, epoxy resin as solidifying agent, and improves hardness and the gloss of film.
In general, improve the consumption of Synolac, the chemical proofing of film and loss of adhesion; Improve content of epoxy resin, then sticking power and resistance to steam performance improve, but coating dryness is poor; The gloss of titanium dioxide content printing performance and film below 40% better but opacifying power is poor, the consumption of titanium dioxide more than 50%, the whiteness of film and opacifying power better, but the gloss difference of printing performance and film.
Based on above-mentioned technical reason, there is following weak point in current tin graphed sheet chalk: formula contains cobalt, manganese class siccative, not environmentally; Epoxy resin for improving sticking power in formula contains harmful material dihydroxyphenyl propane; Resistance to deep draw poor performance, cannot meet the requirement of deep processed product.
In view of this, necessary provide a kind of environment-friendly type, the tin graphed sheet chalk of resistance to deep draw, its formula, not containing cobalt, manganese class siccative, meets the requirement of environmental protection; And containing the material that dihydroxyphenyl propane etc. is harmful in its formula; What is more important, its resistance to deep draw performance is good, can meet the requirement of deep processed product, reaches the deep-draw effect of high-performance Bai Keding.
Summary of the invention
The object of the invention is to: for the deficiencies in the prior art, and provide a kind of environment-friendly type, the tin graphed sheet chalk of resistance to deep draw, its formula, containing cobalt, manganese class siccative, meets the requirement of environmental protection; And containing the material that dihydroxyphenyl propane etc. is harmful in its formula; What is more important, its resistance to deep draw performance is good, can meet the requirement of deep processed product, reaches the deep-draw effect of high-performance Bai Keding.
In order to achieve the above object, the present invention adopts following technical scheme:
A tin graphed sheet chalk for resistance to deep draw, by mass percentage, comprises following component:
Dehydrated castor oil alkyd resin 20% ~ 50%;
Dead front type polymeric polyisocyanate 3% ~ 16%;
Benzene is for aminoresin 3% ~ 15%;
Butylated amino resin 1% ~ 6%;
Dispersion agent 0.3% ~ 1%;
Auxiliary rheological agents 1% ~ 3%;
Titanium dioxide 40% ~ 60%;
Filler 0 ~ 5%;
Whole toner 0.01% ~ 0.1%;
Defoamer 0.1% ~ 1%;
Flow agent 0.1% ~ 1%;
Catalyzer 0.1% ~ 1%;
High boiling solvent 1% ~ 5%.
Wherein, dehydrated castor oil alkyd resin gloss is high, good weatherability, brushability, good leveling property, and it is very fast to the release of solvent, and drying property is good, good to the wettability of pigment, the sticking power of film and snappiness good; And adopt dehydrated castor oil alkyd resin to be base-material, can be made into low temperature curing type tin graphed sheet chalk, adding a small amount of aminoresin can regulate dryness.Dehydrated castor oil alkyd resin and aminoresin share can film-forming well, and the snappiness of film is good, and sticking power is also very desirable.
Dead front type polymeric polyisocyanate is polymkeric substance stable under reacting by the NCO group of polymeric polyisocyanate and encapsulant the normal temperature generated, dead front type polymeric polyisocyanate coordinates with polyol resin, ink stable under can obtaining normal temperature, this ink is under baking condition, encapsulant at high temperature dissociates, release NCO group, thus polymeric polyisocyanate and polyol resin component generation crosslinking reaction, form film.Dead front type polymeric polyisocyanate easily operates, and insensitive to atmospheric moisture.
Solvent, for dissolving other materials, makes other material uniformly dispersed therein.Benzene is good for the compatibility of aminoresin, butylated amino resin and various thermosetting resin, and water-tolerant, good luster, snappiness is good, salt spray resistance, chemical resistance are good, particularly at transfer India side in the face of painted more excellent.Catalyzer is used for playing katalysis, improve the speed of crosslinking reaction between dehydrated castor oil alkyd resin and dead front type polymeric polyisocyanate, reduce solidification value, shorten set time, the hardness improving ink, gloss, moisture resistance and erosion resistance, raising ink mechanical property.
Titanium dioxide and filler can make the viscosity of ink increase, and filler and titanium dioxide need through processed before interpolation, and to avoid consuming part isocyanic ester, titanium dioxide can make whole ink in white.Filler can spread out by dispersion agent effectively, prevents filler from reuniting, and makes the thickening effectiveness of filler homogeneous everywhere.Auxiliary rheological agents is the key component of ink, it can control delicate nature and the feature of fluid product, there is no these medium ink just easy sagging, ink will splashes in coating process, covering power diminishes, and the storage life also can shorten, adopt the mobility of auxiliary rheological agents adjustable ink, reduce the drippage and splashing that occur in roller coat or brushing process, ink viscosity fast and controllably increase, thus improve sag resistance, in ink transport or storage process, auxiliary rheological agents can prevent pigment sedimentation in formula, ensure that the consistence of the finished product, the balance of rationality is reached between weather resistance and good coating characteristics.
In addition, in the present invention, the content of solvent is little, and be only 1%-5%, add the potent thickening power of filler and titanium dioxide, therefore, the special thickness of the present invention, therefore in the course of processing, needs flow agent especially.Flow agent is under dynamic or static conditions, can reduce surface tension, increases wettability, improves the auxiliary agent of levelling effect.If levelling is bad, will cause tangerine peel, shrinkage cavity, brush mark etc. paint film defect, the interpolation of appropriate flow agent then can improve these paint film defects, impels ink in drying and forming-film process, form smooth, smooth, a uniform film.After ink is coated on body surface, increasing sliding auxiliary agent can float over film coated surface, reduces the surface tension of ink, film is reduced second surperficial frictional coefficient, makes film avoid scratching, also can improve the workability of the industrial coating of the serialization of ink.
Whole toner can improve the whiteness of tin graphed sheet chalk, making film seem whiter, by adding different whole toners, can obtain warm colour tone or cool colour tone.In addition, in ink, the existence of foam can cause various problem, and as low in production efficiency, energy consumption increase, print surface defect, production printing are difficult to problems such as carrying out, and defoamer has and excellent presses down bubble and broken bubble function, can reduce surface tension significantly.
Relative to prior art, the present invention is by selecting the content of reasonable component and each composition, it can be made to reach best cross-linking density, thus reduce the generation of internal stress, improve the overall performances such as stretchiness, snappiness, sticking power, make it have the over-all properties that resistance to deep draw, damage resistant etc. are excellent, the requirement of deep processed product can be met, reach the deep-draw effect of high-performance Bai Keding.And its formula is not containing the material that cobalt, manganese class siccative and dihydroxyphenyl propane etc. are harmful, meets the requirement of environmental protection.
Wherein, dehydrated castor oil alkyd resin is short oil dehydrated castor oil alkyd resin; oil content is less than 40; its preparation method is: by Viscotrol C with mix oleic acid (linolenic acid and sunflower seeds oleic acid, the mass ratio of the two is 1:1) by weight 1:1 and mix, under protection of inert gas; be warming up to 250 DEG C; insulation reaction 2h, starts detection reaction device Free Fat acid concentration, controls degree of esterification.After esterification completes, Pintsch process, mixed fatty acid dissociates out again, and Viscotrol C changes into synourin oil.The principle of this step is: with the hydroxyl reaction on the lipid acid such as linolenic acid oleic acid and sunflower seeds oleic acid and castor oil molecule chain,, because the secondary carboxylate generated is unstable, at high temperature there is cracking in i.e. secondary esterification, castor oil molecule chain forms conjugated double bond, obtains synourin oil.
