Aqueous quick-dry coating for synthetic paper combination

Abstract

The invention discloses an aqueous quick-dry coating for synthetic paper combination. The aqueous quick-dry coating comprises a terpene resin, titanium dioxide, a polyamide alcohol-soluble resin, extinction powder, isopropanol, nitrocotton, an aqueous acrylic emulsion, silicon dioxide, ethyl ester and a printing ink electrostatic agent. The coating comprises two layers, which are respectively a connecting layer applied to the surface of synthetic paper and a surface layer applied to the connecting layer. The coating comprises the silicon dioxide, the production and curing time of common synthetic paper is 3-4 days, and after addition of the silicon dioxide, the drying and curing speed of the coating can be shortened to 20-30 minutes, so that the time for curing the synthetic paper can be greatly shortened, and the synthetic paper production efficiency can be improved; with the combination of the connecting layer and the surface layer of the coating, the connecting layer is used for treating the surface of paper, in addition, a function of connecting the surface layer and the paper is achieved, the adhesion effect of the coating can be greatly improved, the surface of the connectinglayer can be modified by using the surface layer, and synthetic paper of a smooth surface can be provided.

Description

technical field [0001] The invention relates to the technical field of coatings for synthetic paper production, in particular to a composite water-based quick-drying coating for synthetic paper. Background technique [0002] Synthetic paper is made by using chemical raw materials such as olefins and adding some additives. It has soft texture, strong tensile strength, high water resistance, light and heat resistance, and can resist corrosion of chemical substances without environmental pollution. , Good air permeability, widely used in the printing of high-end artworks, maps, picture albums, high-end books, etc. According to different structures, it is divided into single-layer synthetic paper, three-layer synthetic paper, and five-layer synthetic paper. [0003] Synthetic paper sometimes needs to be compounded during the production process. Two or more synthetic papers are combined to form a new synthetic paper. The surface of the synthetic paper is generally coated with a c...

Problems solved by technology

[0003] Synthetic paper sometimes needs to be compounded during the production process. Two or more synthetic papers are combined to form a new synthetic paper. The surface of the synthetic paper is generally coated with a coating, which has great performance. Partially determines the quality of the synthetic paper after compounding. There are many problems in the coating currently used, such as the coating is not environmentally friendly, leading to environmental pollution, the performance of the coating is not good, and the synthetic paper is delaminated and peeled off after lamination. , affecting the quality of synthetic paper, and the drying time of the coating is too long, the general synthetic paper drying and curing time is 3-4 days, the efficiency of synthetic paper production is low, and the surface of the coating carries static electricity, which does not effectively eliminate static electricity As a result, the paper cannot be separated as soon as possible during printing, so that the paper is adsorbed together, which leads to the shutdown of the printing machine and reduces the printing efficiency of synthetic paper.
