Embodiment 1

[0041] The preparation of embodiment 1 composition 1

[0042] Disperse 0.3 parts of furnace carbon black, 1.5 parts of isoindolinone, 0.2 parts of phosphite and 4 parts of calcium carbonate in organic solvent isopropanol, vortex for 5 min, and grind until the particle size is about 20 μm to obtain a dispersion. Nano TiO 2 1 part was dispersed in sodium vinyl sulfonate solution to obtain a nano-additive solution. 20 parts of acrylic emulsion, 30 parts of polyethylene terephthalate resin, 10 parts of bisphenol A epoxy resin, Ag + 0.5 parts of complexes with fumaric acid-propylene sulfonic acid copolymers, 5 parts of crosslinking agent monoallyl maleate, 0.2 parts of initiator azobisisobutyronitrile, 5 parts of binder formula III compounds Add the nano-additive solution to the above dispersion liquid, stir at 800r / min for 3h, and adjust the pH to 7.5 with alkali solution to obtain the composition.

Embodiment 2

[0043] The preparation of embodiment 2 composition 2 (not containing binder)

[0044] Disperse 0.3 parts of furnace carbon black, 1.5 parts of isoindolinone, 0.2 parts of phosphite and 4 parts of calcium carbonate in organic solvent isopropanol, vortex for 5 min, and grind until the particle size is about 20 μm to obtain a dispersion. Nano TiO 2 1 part was dispersed in sodium vinyl sulfonate solution to obtain a nano-additive solution. 20 parts of acrylic emulsion, 30 parts of polyethylene terephthalate resin, 10 parts of bisphenol A epoxy resin, 0.5 parts of Ag+ complex with fumaric acid-propylene sulfonic acid copolymer, crosslinking agent Add 5 parts of monoallyl maleate, 0.2 parts of initiator azobisisobutyronitrile and nano-additive solution to the above dispersion, stir at 800r / min for 3h, and adjust the pH to 7.5 with alkaline solution to obtain combination.

Embodiment 3

[0045] The preparation of embodiment 3 composition 3 (does not contain metal ion complex)

[0046] Disperse 0.3 parts of furnace carbon black, 1.5 parts of isoindolinone, 0.2 parts of phosphite and 4 parts of calcium carbonate in organic solvent isopropanol, vortex for 5 min, and grind until the particle size is about 20 μm to obtain a dispersion. Nano TiO 2 1 part was dispersed in sodium vinyl sulfonate solution to obtain a nano-additive solution. 20 parts of acrylic emulsion, 30 parts of polyethylene terephthalate resin, 10 parts of bisphenol A epoxy resin, 5 parts of crosslinking agent monoallyl maleate, initiator azobisisobutyl Add 0.2 parts of nitrile, 5 parts of adhesive compound of formula III and nano-additive solution to the above dispersion, stir at 800 r / min for 3 hours, and adjust the pH to 7.5 with alkaline solution to obtain the composition.

Abstract

The invention discloses a brushable composition capable of realizing color marking of a laser. The brushable composition comprises an acrylic emulsion, polyethylene terephthalate resin, bisphenol A epoxy resin, black pigment, color pigment, a photothermal conversion material, a corsslinking agent, an initiator, a binding agent, a reactive emulsifying agent, an antioxidant and filler optionally added or not added; the composition can be brushed on the surface of a base material, wherein carboxyl in the binding agent and lone pair electrons on nitrogen atoms can form coordinate bonds with metalions on the surface of the base material, so that the fitting degree of the composition and the base material is increased; and the photothermal conversion material is capable of converting light energy into heat energy, so that the laser is marked at relatively small power, in addition, the marking effect is not affected, and the energy is saved.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a brushable composition capable of laser color marking. Background technique [0002] According to the "Product Quality Law of the People's Republic of China" and other laws and regulations, products sold in the market or product packaging must have marks used to identify the product and its quality, quantity, characteristics, characteristics and methods of use, collectively referred to as product identification. The product identification can be brand identification, barcode, product expiration date or batch number, etc. Marking has become an important part of industrial production. The current marking methods mainly include silk screen printing, pad printing, spraying, engraving, laser marking and other methods. In daily production, it is easier to mark on paper products or packages, soft plastic products or packages, whether by spraying or printing, and the cost is lower. However, i...
