Problems solved by technology

[0008] The technical problem to be solved by the present invention: in view of the strong water absorption of the current common water-based ink binder, it is not conducive to the entry and exit of water. If the water-based ink dries too slowly, it will cause poor drying of the printed matter, and the water-based ink dries too quickly, which is easy to cause ink Suspended on the surface of the printing material, the adhesion becomes poor, and there are also defects such as poor heat resistance and water resistance, which cannot meet market requirements. A preparation method for heat-resistant hydrophobic water-based ink binder is provided.

Abstract

The invention relates to the technical field of preparation of macromolecular materials and particularly relates to a method for preparing a heat-resistant hydrophobic type water-based ink binder. According to the method, a modified acrylic emulsion serves as a substrate, modified carbon nanotube powder and modified boric sludge powder serve as accelerants, and a polyoxyethylene-polyoxypropylene copolymer, potassium persulfate and the like are added as auxiliaries, so as to prepare the heat-resistant hydrophobic water-based ink binder; firstly, acrylic resin is modified and is effectively charged inside the water-based ink binder, and thus, the heat resistance, adhesive power and hydrophobicity of the water-based ink binder can be improved; plant essential oil is extracted from rose petalsby using a steam distillation method, and the modified carbon nanotube powder, the plant essential oil and the yoghurt are subjected to blended fermentation, so that the compatibility of the carbon nanotube powder and the substrate is improved; the boric sludge powder is used for reacting with a homemade dispersion solution, and thus, the heat resistance of the water-based ink binder is further improved, so that the water-based ink binder has an extensive application prospect.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a method for preparing a heat-resistant hydrophobic water-based ink binder. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate through printing. Ink is generally composed of pigments, binders, solvents and additives, etc. These components are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. Ink is widely used in various printings such as books, periodicals, packaging and decoration, and architectural decoration. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. [0003] Ink binder is an important part of printing ink and is the fluid part of ink. The rheology, viscosity, drying, film-forming and printing performance of printing ink mainly depend on the binder. The solid component in the ink can be fi...
