Abstract

The invention provides a pear essence for water-based inks, which is composed of the following components in percentage by weight: 1-30% of pear essence, 5-55% of composite modified oligosaccharide and the balance of deionized water. The pear essence is composed of ethyl acetate, propyl acetate, butyl acetate, hexyl acetate, cis-3-hexenyl acetate, isoamyl acetate, ethyl propionate, ethyl butyrate, ethyl 2-methylbutyrate, ethyl hexanoate, ethyl oenanthate, ethyl caprilate, ethyl benzoate, peach aldehyde, hexanal, hydroxy citronellal, trans-2-hexenal, acetic acid, butanol, linalool, damascone, ethyl 3-methylthiopropionate, lemon oil and ethanol. The invention also provides a preparation method of the pear essence for water-based inks. The composite modified oligosaccharide is used as a wall material to be coated on the pear essence so as to form the pear nanocapsule slow-release essence, thereby enhancing the fragrance persistence and water solubility of the essence; and thus, the pear essence is suitable for perfuming the water-based ink. The pear essence for water-based inks has the advantages of fresh and realistic fragrance, high naturalness and high fragrance persistence.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to an essence, in particular to a raw pear essence for water-based ink and a preparation method thereof. Background technique [0002] With the development of modern economy and society, the development of printing industry is gradually considered as one of the symbols to measure a country's industrialization and modernization. Ink is an important material for printing. Compared with traditional solvent-based ink, water-based ink is favored by users due to its environmental protection, low toxicity, health, and resource saving. It has received more and more attention. The current market share The volume is getting bigger and bigger, which has become the development direction of the ink industry today. Water-based ink is also called water-based ink. It is a printing ink made of water-based polymer compound, water-based binder, pigment and related additives, which are compounded and gro...
