Embodiment 1
[0025] The resin matrix is 2 parts of chlorinated polypropylene and 5 parts of cyclized rubber;
[0026] The filler is 5 parts of calcium carbonate;
[0027] The solvent is 5 parts of xylene, 6 parts of butyl acetate, 1 part of butyl lactate, and 1 part of ethanol;
[0028] The additives are 0.8 part of cobalt naphthenate and 0.2 part of castor oil;
[0029] The pigment is 2 parts of azo or phthalocyanine.
Embodiment 2
[0031] The resin matrix is 2 parts of chlorinated polypropylene and 3 parts of cyclized rubber;
[0032] The filler is 4 parts of calcium carbonate;
[0033] The solvent is 5 parts of xylene, 1 part of toluene, 5 parts of butyl acetate, and 1 part of ethanol
[0034] The additives are 0.8 parts of cobalt naphthenate and 1 part of castor oil;
[0035] The pigment is 2 parts of azo or phthalocyanine.
[0036] Using cyclized rubber and chlorinated polypropylene as the resin matrix, add xylene, benzene, butyl acetate, butyl lactate and other solvents to the first reactor at 30-90°C, heat and stir for 0.5-2 hours, and the resin dissolves. A resin mixture is obtained. Add calcium carbonate, castor oil, and ethanol to the second reactor, stir and disperse evenly, then add azo or phthalocyanine pigments, and add a certain amount of toner for color matching, and grind them in a grinder at 50°C Grind two to five times to obtain a pigment mixture. Add the ball-milled pigment mixtu...

Abstract
The invention relates to a screen printing ink for polypropylene plastic. The screen printing ink consists of a resin basal body dissolved in a solvent, and a proper amount of an additive, a filler and coloring pigment; and based on the total weight of the ink, the resin basal body has 20 to 60 weight portions of cyclorubber with molecular weight of between 1,000 and 2,000,000 and cyclizing rate of between 10 and 90 percent, and 10 to 30 weight portions of chlorinated polypropylene. The resin basal body is added to the solvent, is heated and is stirred in a reactor to dissolve the resin out. A mixture of calcium carbonate, castor oil and ethanol is added to another reactor, is evenly stirred and dispersed, is added with the pigment and is ground. After ball milling, the mixture is added to the prior dissolved resin binder and is stirred and dispersed; and slurry is ground in a grinding machine.
Description
【Technical field】 [0001] The invention relates to an ink for plastics and a preparation method of the ink, in particular to a screen printing ink suitable for direct printing on the surface of polypropylene plastics and a preparation method thereof. 【Background technique】 [0002] Polypropylene plastic is polymerized from propylene monomer and is a colorless, odorless, non-toxic non-polar polymer compound. It can be made into thin films and hard plastic products. In the screen printing industry, polypropylene daily-use products, packaging bags, medical equipment products, and industrial woven products are all important types of substrate materials. [0003] Polypropylene plastic is characterized by low polarity, high degree of crystallization, low surface energy, high three-dimensional regularity, and high natural cohesion. It uses general ink screen printing, and its adhesion is extremely poor. Therefore, it is commonly used for etching with complex acid mixture and surface...
