Embodiment 1

[0041] Embodiment 1: Preparation of carboxyl-containing acrylic resin

[0042] Mix methacrylic acid, methyl methacrylate, isobornyl methacrylate, and benyl methacrylate in proportion, stir and heat, add a certain percentage of catalyst azobisisobutylcyanide to the reaction substrate, and control the methacrylic acid , methyl methacrylate, isobornyl methacrylate, and benyl methacrylate are in a ratio of 2:2-3:2-3:1-2, and the catalyst accounts for 1% by weight of the raw material. Adjust the reaction temperature and adjust The ratio of four kinds of raw materials, respectively obtain acid value at 50-200KOH / g, weight-average molecular weight is product acrylic resin A, B, C, D, at 4000-8000, expands the ratio range of four kinds of raw materials simultaneously, makes A The weight ratio of acrylic acid, methyl methacrylate, isobornyl methacrylate, and benyl methacrylate is outside the ratio range of 2:2-3:2-3:1-2, and acrylic resin E, F, G and H. The specific acid value and we...

Embodiment 2

[0046] Embodiment 2: the selection of the thixotropic agent containing silicon dioxide

[0047] The method for measuring silicon content in the thixotropic agent is the molybdenum blue photometric method or gravimetric method, and other methods known in the art can also be used.

[0048] The DBP absorption value of the thixotropic agent is measured according to the method of DIN53601, and the product whose DBP absorption value of the thixotropic agent is 150-250g / 100m1 is selected.

[0049] Select products that meet the requirements of the thixotropic agent according to the above method. The representative products that meet the requirements are matting powder OK412 from Degussa, BYK-405 from BYK, and OK500 from Degussa.

[0050] At the same time, a comparative test is carried out with products that do not meet the requirements. The representative product that does not meet the requirements chooses Grace matting powder RAD2105.

[0051] The silicon content and DBP absorption ...

Abstract

The invention relates to 3D glass light-sensitive black ink composition and a preparation method thereof; the 3D glass light-sensitive black ink composition comprises acrylic resin, a thixotropic agent, epoxy resin and a black pigment and is characterized in that the acrylic resin is carboxyl-containing acrylic resin, a side chain of each polymer unit of a main chain of the carboxyl-containing acrylic resin has more than one carboxyl group, the carboxyl-containing acrylic resin has an acid value of 50-200 mgKOH / g, the carboxyl-containing acrylic resin has a weight-average molecular weight of 4000-8000, the thixotropic agent contains silicon dioxide or organic silicon, wherein silicon accounts for 20-46% by weight of the thixotropic agent, and the thixotropic agent has DBP (di-n-butyl phthalate) absorption value of 150-300 g / 100 ml. coating film prepared with the 3D glass light-sensitive black ink composition has the advantages of high light-sensitivity, high precision, high shaking power, high adhesion and the like, has the excellent effects of boiling resistance, salt spray resistance, acid and alkali resistance, aging resistance and the like, and also has the properties of no wrinkling upon heating and no shedding at high temperature.

Description

technical field [0001] The invention relates to the technical field of 3D glass photosensitive black ink composition, in particular to a 3D glass photosensitive black ink composition and a preparation method thereof. Background technique [0002] The development of the glass cover has gone through three development processes of 2D-2.5D-3D. Compared with the traditional 2D and 2.5D, 3D glass has the advantages of light and thin, transparent and clean, anti-fingerprint, anti-glare, and good weather resistance. It can not only improve The appearance of smart terminal products is novel, and it can also bring excellent touch feel. Generally, since the light-shading frame of the 2D or 2.5D glass cover is made on a plane, it can be realized by direct screen printing, while 3D glass has a certain curvature, and the traditional silk-screen printing process cannot meet the production of the light-shading frame. Therefore, traditional screen printing black ink compositions cannot be u...
