Abstract

The invention provides an antifog / antifrost coating comprising an anion polyelectrolyte copolymer and a preparation method of the antifog / antifrost coating. The antifog / antifrost coating is prepared from the following components by weight percent: 2 to 65 percent of poly(dimethylaminoethyl methacrylate-co-fluoroalkyl methacrylate-co-3-sulfopropyl methacrylate anion electrolyte-co-allyl methacrylate), 0.3 to 10 percent of oligoethylene glycol dimethacrylate, and 0.05 to 0.5 percent of light initiator. The components are prepared into a solution, the solution is smeared on the surface of a surface-modified base material in a droplet coating way, a rotary coating way, a spray coating way or an immersion coating way, and then the base material coated with the solution is cross-linked for 15 to45 minutes in a working way of 365nm and a power range of 15 to 125 W to obtain the antifog coating. By adjusting the constitution ratio of the coating, the hydrophilic and hydrophobic properties canbe balanced, and on the premise of ensuring excellent antifog performance, the coating has good stability. The coating is simple in preparation method, capable of realizing mass production and high in application value.

Description

technical field [0001] The invention belongs to the field of polymer coating materials, and in particular relates to the synthesis of anionic polyelectrolyte copolymers and their preparation methods for anti-fog / anti-frost coatings. Background technique [0002] Fog and frost bring a lot of inconvenience to people's daily life, production and work, and even cause safety hazards. Therefore, research on anti-fog / anti-frost technology has great practical value in production. The traditional methods of heating up by electric heating or spraying anti-fog reagents have the problems of high energy consumption and high cost. Coating anti-fog coating on the surface of the substrate has the advantages of less environmental pollution, low cost, and long duration, and has attracted widespread attention. [0003] Common anti-fog coatings mainly include super-hydrophilic coatings and water-absorbing coatings. Long-lasting anti-fog / anti-frost effects are easier to achieve with absorbent ...
