Long-acting hydrophilic material

Abstract

The invention discloses a long-acting hydrophilic material. The long-acting hydrophilic material is characterized by being mainly prepared from the following components of hydrophilic resin with polymerizing and / or crosslinking active groups, a hydrophilic monomer with polymerizing and / or crosslinking active groups, hydrophobic resin with polymerizing and / or crosslinking active groups, a hydrophobic monomer with polymerizing and / or crosslinking active groups, an ionic surfactant, a curing additive and / or an additive, wherein the type of the hydrophobic resin is the same with the type of the hydrophilic resin; the components are uniformly mixed, and are subjected to thermal chemical reaction or optical chemical reaction, and the hydrophilic components and the hydrophobic components are polymerized and / or crosslinked by chemical bonds, and are entrapped with the ionic surfactant to be compounded together, so as to obtain the long-acting hydrophilic material. The long-acting hydrophilic material has the advantages that the hydrophilic property is high, the effectivity is maintained for a long time, the anti-fog property is high, the wiping-resistant property is excellent, the good adhesion force to a substrate is realized, the optical transparency is high, and the heat stability is high.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to the composition of a long-acting hydrophilic polymer material and a preparation method thereof. Background technique [0002] The hydrophilicity of a material refers to the physical property that the hydrophilic molecules that make up the material can form short-term links with water molecules through hydrogen bonds. Due to the principle of thermodynamics, this molecule can not only dissolve in water, but also in other polar solvents. A hydrophilic molecule, or a hydrophilic portion of a molecule, is one that has the ability to polarize to the point where it can form hydrogen bonds and make it more soluble in water than oil or other hydrophobic molecules . [0003] The hydrophilic properties of materials have broad application prospects in human life, such as: [0004] 1. Anti-fog materials: Glasses, optical lenses, instrument mirrors, windshields, protective glass...

AI Technical Summary

Problems solved by technology

The most typical example is polyvinyl alcohol. Although it has excellent hydrophilic properties, it is completely lacking in commonly used substrate films, such as polyester films, polycarbonate films, polyacrylate films, cellulose films, etc. required adhesion

[0020] Other difficulties in preparing hydrophilic coatings using purely hydrophilic or / water-soluble molecules include: The surface formed by using purely hydrophilic or / water-soluble molecules to prepare hydrophilic coatings is often due to excessive water absorption, making the surface appear dull. Oily, causing the surface to be uneven and not smooth. When exposed to light, it will appear mottled and colorful, which will damage the optical transparency and imaging ability of the material.
