新型新配方水性凹版塑料薄膜油墨

Novel new formula water-based gravure plastic film printing ink

Abstract

本发明新型新配方水性凹版塑料薄膜油墨一般是用于印刷PE、PP、OPP、NY等塑膜的油墨,但也可印刷复合软包装,只要印刷版面没有较大的色块经过复卷冷风检验,复合气味和牢度还是基本可以的,聚酰胺树脂的软化点控制在121度,否则因树脂软化点低在霉雨季节印刷时会出现印品粘连;塑料凹版表印油墨的稀释溶剂是甲苯,异丙醇,二甲苯,丁醇等;也可适时添加一些酯类溶剂来调整油墨的粘度;它具有遮盖力高、不腐蚀承印物和自然挥发干燥的特点;在常温条件下,表干只需15至30分钟,实干6至10小时;稀释剂可选用Ⅱ专用剂。
The invention discloses a novel new formula water-based gravure plastic film printing ink. The novel new formula water-based gravure plastic film printing ink is generally used for printing of PE, PP, OPP, NY, and the like plastic films, and also can be used for printing of composite soft packaging materials only if no large color lump is observed on printing surfaces; and composite smell and fastness are capable of according with requirements after rewinding cold wind detection. The softening point of polyamide resin is controlled to be 121 DEG C, otherwise adhesion of printing products may be caused in mould rain seasons because that resin softening point is low. The dilution solvents of plastic gravure table printing ink are methylbenzene, isopropanol, xylene, butyl alcohol, and the like; certain ester solvents can also be added so as to adjust printing ink viscosity. The novel new formula water-based gravure plastic film printing ink possesses excellent covering capacity; corrosion of printed materials is not caused; and natural evaporation drying can be realized. At normal temperature, surface drying can be realized in 15 to 30min, and complete drying can be realized in 6 to 10h; and II special agent can be taken as a diluent.
