2. Xi'an resin manufacturing chain material process flow

First add benzoin into finely ground resin, raise the temperature to 120°C, stir thoroughly, and heat at a constant temperature (120°C) for 20 minutes. Add the hydroquinone after cooling to 80-60°C. Stir and heat up to 70°C, and then cool down. °C, add stannous chloride, stir well, drop to about 40°C, add benzoin ethyl ether, and mix well until use.

△: When used, 100 g was weighed, and the temperature was raised to about 60°. Methacrylic acid (34.5 g in summer, 17.25 g in winter), vinyl acetate 4.5-22.5 g, and screen printing ink 5.5-11 g were added.

3. The performance and use of major raw materials

(1) Photoinitiator and Preservative: Benzoin, also known as benzoin, benzoin, benzoylmethanol, bitter amaranth, phenyl hydroxy ketone, diphenyl hydroxy ethyl ketone. There are many kinds of photoinitiators, usually taking into consideration the curability, absorption spectrum, stability, color tone, permeability, odor, volatility, ionic reactivity, corrosion, the cost of the swelling of the printing film, ensuring the photoinitiator The stability is primary.

(2) Sensitizer and catalyst: Stannous chloride, also known as tin dioxide.

(3) Assisting resin and cross-linking agent, methacrylic acid, also known as a-methyl propene, isostric acid.

(4) Plasticizer and stripper: dibutyl ester, also known as dibutyl phthalate.

(5) Heat Stabilizer and Inhibitor: hydroquinone, also known as Hyder, Juniner.

(6) Dispersant and Interfacial Adhesive: LJJTM, also known as interfacial adhesive.

(7) Auxiliary resin and cross-linking agent: vinyl acetate, also known as vinyl acetate.

(8) Crosslinker and diluent: styrene, also known as vinylbenzene.

(9) Auxiliary resin and cross-linking agent: Acrylic acid, also known as acetic acid, vinyl formic acid.

(10) Anti-wear agent and ink additive: Polyethylene wax.

According to the above formula design and production process requirements, the ink production method is basically the same as the traditional lithographic ink, but the product is in the use of a certain wavelength of ultraviolet light irradiation, the ink system cross-linking reaction occurs - that is, the oil liquid transition Become solid. Its greatest feature is that it can print on both polar materials and non-polar materials; it can perform both flexographic flexography and transfer lithography directly; neither oven nor hair dryer facilities, nor need to consider dirty Edition into dusting. In the test of the above formula, the effect of the photoinitiator and the LJJ·TM additive in one step and the commercial product of the ink product and LJJ·TM is temporarily adjusted and the trial production is performed. In order to solve photon decomposition, we use commercially available ink and the same brand, the same production date, the same color variety, just add 2-3% LJJ · TM can eliminate the annoying problem of photon decomposition. At the same time, the ink does not need to be heated at minus 5-10°C, and it will flow at high speed as usual. When we form a film (image) from the web, we find that the presence of LJJTM activates the molecules of the ink. Printing film is significantly thinner than the thickness of the same purpose ink, bright, smooth, uniform, anti-sticking, continuous black film, not only increase the adhesion, but also greatly shortened the man-hour, is unmatched by other inks. From the above different examples, we are obsessed with the trend of the era of UV inks, not to grasp the market application of new polar substrates, it will not be able to follow the changes in market needs and change, slow, It may be eliminated overnight by new, cheap, high-quality UV inks. In order not to be eliminated from the harsh and ruthless market economy, we only have to fight for competition. In addition, in order to improve the low cost and high quality of non-absorbing UV offset polar materials, in addition to considering the printability and application range of UV inks, for example, the presence of oxygen in the air can also inhibit the curing of the light solid inks. Effect - leads to a decrease in surface dryness, etc.

The role of additives in addition to the above-mentioned role, reduce the acidity, increase the softening point, reduce the conjugated double bond, improve the anti-oxidation, making it difficult to adhere to the powder, low-temperature flow slow, promote the packaging and printing graphics show various During the color storage, the low-temperature stability, in order to meet the requirements of packaging and printing, to the low-cost, high-quality UV ink brand, participate in the international market competition, to meet the challenges of the 21st century nano-ink technology era.
