Description
Technical field
The present invention relates to a kind of coatings for tin plate printing, relate in particular to mimeograph iron-dope of a kind of outer end, belong to the tank making technology field.
Background technology
Tinplate is again tinplate, is being commonly called as of electrolytic tinplate, and english abbreviation is SPTE, refers to that the two sides is coated with Low carbon cold rolling steel sheet or the steel band of commercially pure tin.Tin mainly plays a part to prevent from corroding and get rusty, and it is incorporated into solidity to corrosion, tin-welding and the appearance attractive in appearance of the intensity of steel and formability and tin among a kind of material, has characteristic corrosion-resistant, nontoxic, that intensity is high, ductility is good.Therefore be widely used in each fields such as every profession and trade such as packaging vessel (tank processed, tubbing and food-drink packing), electronic product, household electrical appliance, automobile, motorcycles, certainly, when described packaging vessel is applied to field of food, should strictly observe the regulation of relevant law.
Along with the development of China's packaging industry, tank industry processed has also had huge development, and this development has driven the development of relevant industries-coatings for tin plate printing.Coatings for tin plate printing belongs to thermosetting coating, and process printing or roller coat are coated with and install to the metallic surface, and then heated baking makes its crosslinking curing, forms tough and tensile filming.Coatings for tin plate printing (tin printingink) is one of planographic ink, is applied to letterest printing machine and wet type offset printing mode and prints iron sheet (tinplate) and process the general name that the metals such as steel plate, aluminium sheet are used printing ink.Coatings for tin plate printing has dividing of interior coating, outer layer coating; Rustproof lacquer can be divided into again oil of the outer end, printed form chalk and roller coat type chalk, colored ink, Lacquer finish wet goods.
The main characteristic of coatings for tin plate printing is strong to sticking of tinsel, and erosion resistance, anti-boiling, anti-baking, anti-solvent, fast light and processibility good (moulding, die-cut, seam etc.).The dried forms of coatings for tin plate printing has baking-type and ultraviolet curing type.in traditional tin graphed sheet technique, the dried forms of coating is baking-type, be that described coatings for tin plate printing is the thermofixation coatings for tin plate printing, its sticking power is good, alkali resistance also shows excellence, but the problem of thermoset coatings for tin plate printing maximum is that the speed of its curing is slow, its individual drying time reaches 35-40min, because drying time is long, can't realize continuous production, causing present tinplate to be coated with Huang whitewashes the tin graphed sheet unit and mostly still adopts the mode of operation of individual tin graphed sheet, this technique storing time is long, working hour and cycle are of a specified duration, energy consumption is large, individual tin graphed sheet lacks handiness and originality
The UV coatings for tin plate printing is to utilize UV-irradiation, make the photochromics molecular breakdown form overactivity atom or overactivity atomic group, these overactivity atoms and atomic group make the organic compound that contains unsaturated link(age) induce a series of light-initiated chain reaction, reaching at last molecule crosslinked polymerizing curable drying purpose, is a developing direction of coatings for tin plate printing.But the sticking power of UV coatings for tin plate printing is relatively poor, is not easy to carry out colored drawing thereon, and also effective not as the thermofixation coatings for tin plate printing in the performance of the aspects such as alkali resistance, anti-post-treatment, snappiness, wear resistance.
The tin graphed sheet wash primer is that the one deck between tinplate and printing ink links agent, and its effect is that printing ink or whitewash can be attached on tinplate securely.Tin graphed sheet tank processed is generally first to print, aftershaping, therefore in the courses of processing such as bending, stretching, welding, flange, seaming, except the coating rete that requires to parch and ink lay have enough intensity, also require them to tinplate, enough sticking power to be arranged, in order to avoid produce paint film and ink lay excessive deformation, cracking, the phenomenon that even comes off from tinplate in the machine-shaping process.
For the operational condition in tin graphed sheet technique, the performance of oil generally has following requirement for the outer end:
(1) transparency is good, after drying and forming-film yellowing little, do not hide the metal-like of tinplate;
(2) good levelling property is arranged, suitable thermoset and snappiness are beneficial to following process;
(3) printing ink or whitewash there are enough affinities, all kinds of tinplates are had good tack;
(4) after film forming, good water resisting property is arranged, be beneficial to printing.
To sum up, how to develop a kind of set time short, can realize that preferably continuous brushing purpose coatings for tin plate printing is one of this area problem demanding prompt solution.The sticking power of described coatings for tin plate printing, intensity and anti-processibility aspect also should show excellence, and every physicochemical property (as levelling property, hydrophobicity etc.) also should show well.
Summary of the invention
For the deficiencies in the prior art, one of purpose of the present invention is to provide a kind of set time short, can realize the coatings for tin plate printing of continuous brushing purpose, described coatings for tin plate printing sticking power, intensity and anti-processibility aspect performance excellent, and it has good levelling property and hydrophobicity.
The present invention is achieved through the following technical solutions:
