Problems solved by technology

However, the screen-printing baking ink needs to be baked, which limits its scope of use. It cannot process the graphics and images of some large and complex precision components, and it cannot be used for some temperature-sensitive materials.
In addition, baking photosensitive ink requires a relatively large investment due to the need for baking equipment; it also consumes a lot of energy, which is not conducive to resource conservation

[0034] B. Preparation of alkali-soluble photosensitive resin: butyl acetate, methyl i...

Embodiment 1

[0042] Add 20 parts by weight of butyl acetate and 20 parts by weight of methyl isobutyl ketone into the reactor and raise the temperature to 95°C, add 40 parts by weight of styrene-maleic anhydride resin, add 15 parts by weight of hydroxyethyl acrylate, 6 parts by weight Hydroxypropyl acrylate, 0.1 parts by weight of tetraethylammonium bromide, and 1.0 parts by weight of p-tert-butylcatechol were kept at a constant temperature for 25 hours, and then the temperature of the reaction system was lowered below 60°C to obtain the required alkali-soluble photosensitive resin. Take by weighing 50 parts of the aforementioned alkali-soluble photosensitive resin according to the weight fraction ratio, 5 parts of cellulose acetate butyrate, 2 parts of trimethylolpropane triacrylate, 2 parts of 2-methyl-1-(4- Methylthiophenyl)-2-morpholino-1-propanone, 26 parts of talc, 0.5 parts of phthalocyanine blue, 11.5 parts of ethyl acetate, 3 parts of BYK306. Add the aforementioned alkali-soluble...

Embodiment 2

[0052] Weigh according to the weight ratio: the alkali-soluble photosensitive resin prepared in Example 1: 80 parts, 2 parts of pentaerythritol tetraacrylate, 2 parts of benzophenone, 40 parts of barium sulfate, 0.5 part of phthalocyanine green, 5 parts of toluene, 1 part of Deqian 410. Add the above-mentioned alkali-soluble photosensitive resin, active diluent, filler, and pigment weighed into a high-speed disperser to disperse and stir, and then add photosensitizers, additives, and solvents to the high-speed disperser to disperse and stir for 25 minutes to obtain a semi-finished product. Grinding by three-roll machine for 3 times until the fineness is below 15um, the self-drying photosensitive anti-acid corrosion and electroplating anti-plating ink of the present invention is obtained. The performance test results are as follows:

Abstract

The invention discloses a naturally dried photosensitive acid-corrosion-resistant electroplating printing ink and a preparation method thereof. The naturally dried photosensitive acid-corrosion-resistant electroplating printing ink comprises the following components in parts by weight: 50-80 parts of alkali soluble photosensitive resin, 0-5 parts of cellulose used for coating, 2-10 parts of active diluents, 2-8 parts of photosensitizer, 10-40 parts of filler, 0.5-1 part of pigment, 5-15 parts of solvent and 0.5-3 parts of auxiliaries, wherein the alkali soluble photosensitive resin is prepared from the following components in parts by weight: 40-60 parts of mixture consisting of 20-30 parts of n-butyl acetate, 0-30 parts of methyl isobutyl ketone, 0-20 parts of methylbenzene and 0-20 parts of propylene glycol monomethyl ether acetate, 25-40 parts of styrene-maleic anhydride resin, 15-20 parts of acrylic acid monomer, 0.1-1.0 part of catalyst and 0.1-1.0 part of polymerization inhibitor. The naturally dried photosensitive acid-corrosion-resistant electroplating printing ink disclosed by the invention does not need baking, is dried naturally after being diluted and is energy-saving and is resistant to acid and electroplating, and a film formed after the electroplating printing ink sprayed and dried naturally is high in adhesive force, high in hardness, quick in development, capable of obtaining clear images and resistant to acid corrosion.

Description

technical field [0001] The ink of the invention particularly relates to a self-drying photosensitive anti-acid corrosion and electroplating ink. [0002] The present invention also relates to a preparation method of the self-drying photosensitive anti-acid corrosion and electroplating ink. Background technique [0003] Nowadays, photosensitive technology is widely used in the production of signs, panels, and decorative product graphics. In addition, photosensitive technology is also used in the processing of precision hardware products to obtain precise graphic images. There are many ways to obtain precise images and images on metal surfaces, such as the bone glue mask method using dichromate as a photosensitizer, the dry film method, and the wet film method. Bone glue mask is a serious pollution source and carcinogen, which is extremely harmful to the human body, and is basically not used now; dry film technology does not meet the requirements for precise graphics and imag...
