Abstract
The invention discloses a vegetable oil type hectograph printing ink and a preparation method thereof. The printing ink is prepared by the following method: firstly producing a resin meeting the requirements of an offset printing ink through the esterification reaction of waste vegetable oil monoacid via a chain extender and a polyol; then carrying out the esterification reaction of the waste vegetable oil monoacid and the mono-alcohol or polyol under the action of a catalyst to generate waste vegetable oil monoacid mono-alcohol monoester or waste vegetable oil monoacid polyol monoester capable of replacing mineral oil to produce the offset printing ink; and finally preparing the vegetable oil hectograph printing ink through the offset printing ink resin prepared through the waste vegetable oil monoacid, a solvent and a pigment for the offset printing ink, wax, a gelling agent and a levelling agent. The prepared printing ink has a high color density, a moderate viscosity and a good printing adaptability, and solves the aggregation problems of greenness, environmental protection and resource recycle for the offset printing ink.
Description
Technical field
The present invention relates to a kind of vegetable oil type hectograph printing ink and preparation method thereof, belong to printing ink manufacturing technology field.
Background technology
The vegetables oil printing ink domestic large-scale producer of polyamide resin, nearly 8500 tons of annual manufacture of ink with polymeric amide, wherein need about 6000 tons of vegetables oil dimeracid, in the production process of dimeracid since polymeric ununiformity polymer have after finishing: 5% trimer acid, 60% dimeracid and 35% not polymerisable waste vegetable oil unit acid.Because the acid of waste vegetable oil unit is unfavorable for the polymerization chain extension polymerization of printing ink with the polymeric amide next stage, therefore, the acid of waste vegetable oil unit must be extracted with the distillatory mode, abandon as by product.The annual therefore depleted waste vegetable oil unit acid of factory reaches more than 2,000 ton.
Environmental protection production sustainable development is the main flow of the development in recent years of current enterprise, how to utilize the acid of waste vegetable oil unit, update in the printing of solution flexographic ink environmental protection package, and guarantee that it is urgent problem that the printed matter safety non-toxic does not contain natural Dioxins.
