Abstract

The invention provides water-based gravure polishing oil and is characterized in that the water-based gravure polishing oil is prepared with the following raw materials in percentage by weight: water: 10-25; alcohols solvent: 5-20; emulsion: 20-45; solid resin: 5-25; amine assistant: 5-15; foam killer: 0.1-0.5; anti-wear additive: 0.5-5; flatting agent: 0.1-3; and film forming assistant: 1-5. Theinvention further discloses a polishing oil preparing method. Compared with the traditional gravure polishing oil, through the adoption of more reasonable raw materials, the water-based gravure polishing oil has the advantages of stable quality, innocuity, zero environment pollution, no solvent volatilization, high glossiness, strong abrasion resistance, low probability of yellowing and good adhesive attraction, can improve production environment, and is favorable for the health of operating staff; and the attenuant can be water and also can be the mixture of alcohols solvent and water with the ratio of 1 to 1 according to specific circumstances, so that the use cost of attenuant is greatly reduced.

Description

Technical field [0001] The present invention involves a type of optical oil, especially a water -based concave printing,; the present invention also involves a preparation method of the aforementioned optical oil. Background technique [0002] Caval printing is suitable for various alcohol labels, smoke marks and various high -end paper (such as copper version paper, cardboard, composite paper, etc.) printing materials.Can play a role in protecting and decorating printed materials.At present, the gravites used in the gravure oil are the solvent type of light oil, the printing is low, the anti -rubbing resistance is poor, and the VOC contains VOC, which has a destructive effect on the health and production environment of the operator. Invention content [0003] The technical problems to be solved by the present invention are the lack of existing technologies, providing a new formula for the more reasonable, high gloss, strong abrasion resistance, and safe and stable water. [000...
