Problems solved by technology

At present, there are two main ways to improve the tactility of paper printed matter. One is biaxially oriented polypropylene (BOPP) tactile film, which has good various properties, but it is not biodegradable and is not an eco-friendly material.
The other is to apply water-based tactile oil, which has disadvantages such as poor wear resistance, intolerance to alcohol, and poor anti-blocking properties.

Abstract

The invention provides water-based UV touch oil and a preparation method thereof, belonging to the technical field of touch oil. The water-based UV touch oil is prepared by mixing a main film-forming substance, namely a water-based self-extinction polyurethane emulsion, an ultraviolet curing component, namely water-based urethane acrylate, an acrylic UV monomer and other additives. After the water-based UV touch oil is subjected to ultraviolet curing to form a film, the wear resistance, the anti-blocking performance and the alcohol resistance of a touch coating are greatly improved. In this way, the excellent characteristics of the waterborne self-extinction polyurethane are reserved, the abrasion resistance, alcohol resistance and anti-blocking performance of the touch coating are improved through ultraviolet curing, and the curing method further has the advantages of rapid curing, environmental friendliness and capability of saving energy. Besides, the waterborne self-extinction polyurethane emulsion contains large-particle-size particles (0.1 [mu]m to 0.3 [mu]m), so the microcosmic roughness of a film-forming surface is increased, good matte effect and tactile sensation are obtained, and public preferences are conformed to.

Description

technical field [0001] The invention relates to the technical field of tactile oil, in particular to a water-based UV tactile oil and a preparation method thereof. Background technique [0002] Nowadays, with the rapid replacement of new materials in the printing field, people prefer prints with smooth velvet surface, soft elasticity and matte effect. Printed matter also allows people to experience visual and tactile feelings different from traditional printing effects through the use of special materials, special processes and special equipment. At present, there are two main ways to improve the tactility of paper printed matter. One is biaxially oriented polypropylene (BOPP) tactile film, which has good various properties, but it is not biodegradable and is not an eco-friendly material. The other is to apply water-based tactile oil. This kind of water-based tactile oil has disadvantages such as poor wear resistance, intolerance to alcohol, and poor anti-blocking propertie...
