Abstract

The invention relates to heat-set ink used for textile printing and a preparation method of the heat-set ink. The heat-set ink used for textile printing is characterized by comprising the following components in parts by weight: 10-40 parts of chloroethylene-vinyl acetate copolymerization paste resin, 20-60 parts of plasticizer, 1-3 parts of stabilizing and 2-7 parts of rheological additive, wherein the polymerization degree of the chloroethylene-vinyl acetate copolymerization paste resin is 1,000, the K value is 62-69, and the weight percentage of the vinyl acetate component is 3-8%. Phthalic acid ester plasticizers are not contained in the heat-set ink used for textile printing, and the curing temperature of the heat-set ink used for textile printing is between 120 DEG C and 140 DEG C.

Example Embodiment

[0030] Example 1

[0031] The formula is as follows:

[0032]

[0033] The vinyl chloride-vinyl acetate copolymer paste resin is KM-31 produced by Hanwha Corporation in South Korea, with a polymerization degree of 1000, a K value of 62-69, and a vinyl acetate composition of 3%-8%.

[0034] The plasticizer is made up of 60% of GL-300 (the ingredient is terephthalate (DOTP)) produced by South Korea’s LG Chemical and 40% of phenyl alkylsulfonate produced by Puyang Yifeng New Plasticizer Co., Ltd. composition.

[0035] The rheology additive is BYK-410 produced by BYK in Germany (the ingredient is a modified organic urea solution).

[0036] The stabilizer is AkcrosNobel environmentally friendly non-toxic calcium zinc stabilizer (liquid) (Lankros tat C 19).

[0037] The production process is as follows:

[0038] step 1. First add 120kg of plasticizer and stir slowly with a frequency conversion dispersing mixer;

[0039] Step 2. Then add 60kg of paste resin, slowly add and stir, do not disperse at high speed to cause the plastisol to form high temperature, paste resin can dissolve in the plasticizer without obvious particles;

[0040] Step 3. Then slowly add 2kg of stabilizer until the dispersion is uniform;

[0041] Step 4. Then add 3kg of rheological additives and disperse at a medium speed. The temperature of the plastisol should not exceed 45 degrees. The mixing time should be uniformly dispersed with the rheological additives until the plastisol is evenly thin and thick;

[0042] Step 5. Put the thickened plastisol on a three-roll mill for grinding once, then quality inspection and packaging.

[0043] Example 2

[0044] The formula is as follows:

[0045]

[0046] The vinyl chloride-vinyl acetate copolymer paste resin is KM-31 produced by Hanwha Corporation in South Korea, with a polymerization degree of 1000, a K value of 62-69, and a vinyl acetate composition of 3%-8%.

[0047] The plasticizer is GL-300 (the ingredient is terephthalate (DOTP)) produced by 80% of South Korea’s LG Chemical and 20% of trioctyl trimellitate produced by Shandong Kexing Chemical Co., Ltd. ( Referred to as TOTM).

[0048] The rheology additive is M5 produced by Degussa, Germany (the ingredient is non-crystalline fumed silica).

[0049] The stabilizer is AkcrosNobel environmentally friendly non-toxic calcium zinc stabilizer (liquid) (Lankros tat C 19).

[0050] The production process is as follows:

[0051] Step 1. First add 100kg of plasticizer and stir slowly with a frequency conversion dispersion mixer;

[0052] Step 2. Add 60kg of paste resin again, slowly add and stir, do not disperse at a high speed to cause the plastisol to form high temperature, the paste resin dissolves in the plasticizer without obvious particles;

[0053] Step 3. Next, slowly add 2 kg of stabilizer until the dispersion is uniform;

[0054] Step 4. Then add 12kg of rheological additive and disperse at a medium speed. The temperature of the plastisol should not exceed 45 degrees. The mixing time should be evenly dispersed by the rheological additive until the plastisol has a uniform consistency;

[0055] Step 5. Put the thickened plastisol on a three-roll mill for grinding once, and then quality inspection and packaging can be achieved.

[0056] The transparent jelly thermosetting ink of the present invention and the transparent jelly thermosetting ink of American Welfis and Italy Wanlinglong are respectively printed according to the following process conditions.

[0057] The printing process is as follows:

[0058] Use a 120-200-mesh screen, a right-angle squeegee with a hardness of 65-75 degrees, and the substrate is an ordinary stretch fabric.

[0059] Step 1: Place the fabric on the printing table, pay attention to flattening, adjust the screen distance between the screen and the substrate, and adjust the screen positioner;

[0060] Step 2: Put the ink on the screen printing plate and manually scrape the printed pattern with a squeegee for the first time, adjust the printed pattern with a heat gun to adjust the temperature to dry the surface. Note that the surface drying temperature is generally 80℃-100 ℃;

[0061] Step 3: Perform manual scraping again for the second time, or after drying the surface with a hot baking gun. Repeat the procedure of the second step above 4 times, and finally get a certain printing thickness of the ink coating;

[0062] Step 4: Set the electric baking tunnel to 120°C, 130°C, 140°C, and 150°C. The tunnel baking time is always set to 180 seconds, and the printed sample is placed in the electric baking tunnel for baking.

[0063] Table 1 shows the comparison of elongation of products produced with different K values of vinyl chloride-vinyl acetate copolymer paste resin.

[0064] Table 2 shows the performance comparison between the product of the present invention and the transparent gel thermosetting ink made by American Weifeishi and Italy Wanlinglong.
