Problems solved by technology

However, the existing water-based coating materials for anti-electromagnetic radiation clothing have poor absorption capacity for electromagnetic waves, and the absorbent powder is easy to precipitate and delaminate from the adhesive during storage, and must be dispersed again before use, which is not conducive to water-based coatings. The long-term storage of membrane materials increases the use of water-based coating materials.

Abstract

The invention discloses a waterborne coating material for a touch screen as well as a preparation method and application thereof. The waterborne coating material is prepared from the following raw materials in parts by weight: 70 to 80 parts of polyurethane acrylate composite emulsion, 15 to 20 parts of glucose, 1 to 2 parts of iron powder, 0.6 to 1.0 part of nickel powder, 2 to 4 parts of dipropylene glycol methyl ether, 0.8 to 1.0 part of a de-foaming agent, 0.2 to 0.3 part of a wetting agent, 0.15 to 0.25 part of a slipping agent and 0.2 to 0.3 part of a flatting agent. The waterborne coating material prepared by the preparation method has good transparency after being sprayed on the surface layer of the touch screen and cured; composite nano-spheres are arrayed directionally in a coating curing process, so that a coated surface is rough and the glare can be reduced; the composite nano-spheres can be used for absorbing and attenuating emitted electromagnetic waves, converting electromagnetic energy into heat energy and dissipating the heat energy, so that the electromagnetic radiation strength in the environment is improved, and a long-period accumulation effect, caused by electromagnetic radiation, on human bodies is weakened, so that damages, caused by harmful radiation, to human bodies are solved radically; the composite nano-spheres have good dispersity and strong storage stability in the polyurethane acrylate composite resin emulsion.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a water-based coating film material used for touch screens and a preparation method and application thereof. Background technique [0002] Electromagnetic radiation is an electric field and a magnetic field that oscillate in phase and are perpendicular to each other, moving in the form of waves in space, and its propagation direction is perpendicular to the plane formed by the electric field and magnetic field, effectively transferring energy and momentum. Electromagnetic radiation can be classified by frequency, from low to high frequencies, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, to name a few. [0003] Today, with the rapid development of information technology, electronic products that realize human-computer interaction technology through touch screen technology have brought great convenience to human beings.
