At present, in the packaging and printing, environmental protection high temperature resistant,
121℃～150℃)
Screen printing ink has become the focus of attention.
The so-called environmental protection high temperature resistant screen printing ink, is in the process has been completed by screen printing packaging products surface, make the printing figure ink layer can adapt to heat the water solubility of ink layer, and has certain water resistance, rise to match the substrates with the environmental protection and adornment effect of the ink.
environmental protection high temperature the screen printing ink will not change its by environmental protection, high temperature resistant process. But the feature is to adjust the ink diluted with purified water, especially when printing products under a certain temperature, the printing ink ink film will improve the adhesion fastness, and not as a result of environmental heat softening of ink film, adhesion and cause defective or destroyed. Products can be according to the needs of users and the actual printing process, for different screen printing technology. Therefore, focusing on the formulation of the product here a brief introduction of the design and application range.
water of high temperature resistant screen printing ink features:
, high temperature resistant screen printing ink is non-toxic, tasteless, no volatile organic solvent, low cost, material source wide, good gloss, analysis resistance, heat resistance, abrasion resistance and resistance to water washing, economic health, etc.
, high temperature resistant screen printing ink according to the product use, can be divided into: high gloss, gloss and matt 3 kinds. From the silk screen process can be divided into: manual screen printing and rotary screen printing rotary screen. Water-based printing high temperature resistant ink in use process, can eliminate the harm to human body and the pollution to the environment, has begun to be food, artificial leather, bags and other packaging printing enterprises.
in addition to environmental protection, printing high temperature resistant ink compared with solvent-based printing ink also has the following advantages:
after printing film speed, dry quickly. Water of high temperature resistant screen printing ink drying process is 60% by evaporation or volatile, 40% by infiltration absorption material, dry quickly, about a few minutes or dozens of minutes to complete the printing ink by conjunctiva. If use infrared or hot air drying method can promote its membrane drying.
the use and storage is convenient, safe, and conducive to the safe production and improve the staff's working conditions operation. Due to solvent or oily screen printing ink, belong to the category of dangerous goods, transport, warehouse storage, use very inconvenience. And environmental protection high temperature resistant, screen printing ink with water as solvent, no danger, the use of safe and reliable, usable water cleaning equipment and cleaning the fingers.
avirulent insipidity. Due to water-based printing ink with water as solvent, a small amount of volatile edible alcohol as the auxiliary solvent, therefore particularly suitable for food, clothing, leather and plastic substrates.
good resistance to high temperature and heat sealing. Water-based printing ink has a good heat sealing performance, even with PE, PVC can obtain good effect of heat sealing.
finished goods good flowing property, crimp resistant ability. A headache in the printing is printing substrates after several color group of continuous dry, paper moisture content is extremely low, or easy to produce transverse or longitudinal contraction of PVC, artificial leather, easy to curl, so can't normal production or use. Application of the ink products after printing, decoration, hot stamping, cutting, can still maintain good flatness and crimp resistance.
the price is reasonable. General than the current commercially available water-based printing ink solvent printing ink low prices by about 30%, this has provided the price to expand market share advantage conditions.
in addition to the above advantages, high temperature resistant, silk screen printing ink used on cylinder rotary press, the operation method and the traditional solvent-based screen printing inks are nearly the same. But the point is the product of the PH control, viscosity, dry, silk screen mesh selection, oven or bake, temperature control, and under the condition of wet printing, the ink may not be fully dry and dragged, or pollution color sequence. In particular, how to prolong the drying time will be the focal point of the packaging and printing industry. On the other hand, it can be applied to the flexible gravure rotary printing machines.
heat resistance and washing resistance. The ink is usually resistant to 121 ℃ ~ 150 ℃, for some special packaging and printing products provides an operational platform. Especially the ink in the past often will be caused by the rise of temperature or humidity to stick or adhesion, bleached. Especially leatherette glazing after printing process such as tend to make the ink ink film become soft, deformation, migration caused the abandonment of the products. Second, even in use process for dyeing and printing process, because the ink film is not washing, lead to fade, rub off. The environmental protection high temperature resistant screen printing ink, usually by means of high temperature after curing figure ink film branched degree increase and strengthened the water resistance of the product.
high transparency. Substrates light, can be long-term preservation in print, under the strong sunlight, not easy yellowing, color and fade.
high resistance to wear. Packaging and printing accessories need strong wear resistance, per square centimeter, 50 pressure measurement shall generally be per minute 150; Are generally light, brightness can reach 50 to 70 units. As a result, the packaging printing products should not only wear-resistant, resistant to 30 points ` eight d_? Clock washed, and as high as 121 ℃ ~ 150 ℃ ( 3 seconds to 10 seconds) When can meet this requirement.
environmental protection high temperature the screen printing ink will not change its by environmental protection, high temperature resistant process. But the feature is to adjust the ink diluted with purified water, especially when printing products under a certain temperature, the printing ink ink film will improve the adhesion fastness, and not as a result of environmental heat softening of ink film, adhesion and cause defective or destroyed.
