Problems solved by technology
[0004] Aiming at the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to design a special water-based ink for decorative paper with better dispersibility, no layering of ink, less edge collapse of subsequent processed products, and better color fastness. And at the same time, it only needs to be produced under normal temperature and pressure, energy saving, high work efficiency and low raw material cost.

Embodiment 1
[0015] Example 1 (corresponding raw materials and proportioning values of Example 1 in the comparison table): 19 parts of water-soluble red powder, 30 parts of ammonia-soluble acrylic resin, 4 parts of polyether surfactants, 5 parts of isopropanol, 40 parts of industrial water , first use 32 parts of them (reserve 8 parts for final washing), 0.8 parts of MB-16 preservative, add them to the container one by one, stir and mix evenly, move to a sand mill for sanding and disperse, and then use the remaining 8 parts Rinse the remaining mixture in the container with water and move it to a sand mill for sanding and dispersing. When the fineness of the mixture is 10-25 μm, the sanding and dispersing are completed, and the material is discharged into a barrel to make the red water-soluble ink specially used for this decorative paper. The fineness of the ink is 20μm, the viscosity is 25S in 4 cups at 20°C, the solid content is 25%, pH=8.5, and the color fastness compared with blue wool...

Abstract
The invention provides a special water-based ink for decorative paper, which is formed by proportioning the following raw materials in weight portion: 16 to 22 portions of water-soluble toner, 27 to 33 portions of water / ammonia-soluble acrylic resin, 2 to 6 portions of polyether-type surfactant, 3 to 7 portions of isopropyl alcohol, 37 to 43 portions of water and 0.5 to 1.1 portions of MB-16 as a preservative. The pH value of the ink is 8 to 9; the viscosity of the ink is between 22 and 28 S, which is measured by a 20-DEG C TU-4 cup; the fineness of the ink is between 20 and 25 mu m; the solid content of the ink is between 20 and 28 percent; and the color ratio resistance degree of the ink is more than or equal to 6 in contrast with blue wool. A method for producing the special water-based ink for decorative paper comprises the following steps of preparing and weighing raw materials, mixing and evenly stirring the raw materials, sand-milling, dispersing, barreling, inspecting and leaving factory. The water-based ink is specially used for printing decorative paper patterns, and has the advantages that the water-based ink is good in dispersity, free from ink delamination, difficult to cause edge crack to subsequent processed products and good in color resistance fastness. The method for producing the ink has the advantages of energy saving, high work efficiency, and lower raw material cost.
Description
technical field [0001] The invention relates to a water-based ink. Background technique [0002] The dispersibility of domestic water-based ink for decorative paper is not ideal, and it is prone to disadvantages such as floating color and ink layering. The decorative paper printed with this kind of ink is easy to collapse in subsequent processed products such as flooring, and its color fastness is also poor. Poor. Although similar imported inks have no obvious above-mentioned defects, they are expensive. [0003] CN1237602 discloses Wu Ping's patent application for "water-based ink formula and production process for cartons". In its production process, the adhesive is prepared first, and rosin, water, triethylamine, and surfactant need to be heated to 55 in the reaction kettle. ℃—80℃ for 2 hours, consumes energy, and needs to be cooled before adding diluent, adhesive spreader, ethanol, low work efficiency, and easy to produce bubbles during use, requires defoaming agent, c...
