Problems solved by technology

[0006] The gloss of paint and ink is mainly produced by the emulsion conjunctiva. The gloss has a great influence on the appearance of paint or ink products. The gloss is high, the color is bright, it looks more energetic, and it meets people's inner needs; gloss If the degree is poor, the color will be dull, giving people a feeling of staleness and depression, which will greatly reduce the promotional effect of the product
At present, water-based inks and water-based coatings generally have the disadvantage of insufficient gloss. In addition to external light sources, substrates and other reasons, the composition and properties of inks and coatings themselves will play a decisive role in gloss.

Abstract

The invention discloses an internal plasticizing monomer-modified acrylate / inorganic nano composite emulsion and a preparation method thereof. The raw material of the internal plasticizing monomer-modified acrylate / inorganic nano composite emulsion is composed of the following components by weight percent: 30-60% of acrylate monomer, 1-10% of internal plasticizing monomer, 1-10% of inorganic nano-materials, 0.1-1% of initiator, 1-10% of emulsifier, 0.01-1% of buffer agent, 0.01-1% of lauryl mercaptan and the balance of deionized water. The internal plasticizing monomer is directly pre-emulsified together with the acrylate monomer in the preparation method; the inorganic nano-materials are directly added one time. The production process is simple in required equipment, convenient to operate, low in cost and high in safety. The acrylate emulsion is comprehensively modified by adopting the internal plasticizing monomer and the inorganic nano-materials, so that the composite emulsion has high strength after film formation, the toughness is also greatly improved. and the glossiness and the heat resistance are also greatly improved; the application scope of the emulsion is broadened.

Description

technical field [0001] The invention relates to a modified acrylate emulsion, in particular to an internal plasticizing monomer modified acrylate / inorganic nanometer composite emulsion and a preparation method thereof. Background technique [0002] Acrylate emulsion uses water as the medium, which is safe in production and has little environmental pollution. It overcomes the fatal shortcomings of solvent-based polymers and meets people's requirements for environmental protection of chemical products. And the process is simple, easy to operate, and flexible; and this type of emulsion has excellent performance, good stability (storage, freeze-thaw, machinery, etc.), high film transparency, good gloss, aging resistance, water resistance and Excellent acid resistance. These advantages endow acrylate emulsions with a wide range of uses, which can be used in water-based paints, writing materials, adhesives, and functional films, and are increasingly used in industries such as con...
