Description

technical field [0001] The invention provides a basic adhesive material for water-based varnish (abbreviation: base material) and its preparation method, which are used to beautify and protect color printing and packaging paper products, so that they can withstand high and low temperature, high humidity, load and other environments. A basic material that is resistant to impact, collision, friction and corrosion by certain chemicals, and belongs to the field of color printing and packaging. Background technique [0002] "Paint" is divided into varnish (abbreviation: "oil") and color paint. "Oil" (varnish) is mainly used for "glazing" and "protection" on the surface of materials, so it is called "varnish". "Varnish" is composed of two parts: "base material" + "auxiliary". Effect. "Glossing" is to beautify colored paper products, and "protection" is to meet various functional requirements for beautified colored paper products. The higher the protection level for the functio...
