Research On Preparation And Application Of Transparent Hydrophilic Antifogging Acrylate Resin

An effective antifogging method to avoid the fogging of the glass of silicate for ornament is to coat a layer hydrophilic antifogging coating.Acrylate resin which has excellent anti-fogging and water-soluble performance is a long transparent antifogging material.The main contribution of this paper is summarized as follow:1 Copolymer acrylate resin including hydroxyl(-OH), carboxylic(-COOH) and amina(-NH₂) is a new type of antifogging system and ahydrophi- lic antifogging constituents which is not found before.2 Water-soluble acrylate resin hydrophilic antifogging coating material is a new-type environmental protection material which takes ethanol as solvent and whose pastiness is adjusted by deionized water.3 The quality rate of accessory soft monomer ethyl acrylate and accessory hard monomer butyl methacrylate is 6 to 4, the quality rate of functional monomers in all monomers is 20 percent, the quality rate of MAA in the functional monomers is 22 percent, the quality rate of β-hydroxyl ethyl acrylate in the functional monomers is 8 to 10 percent and the remainder of functional monomer is acrylic acid.4 Cross-linking agent methylol acrylamide belongs to self-cross-linking system. The quality rate of cross-linking agent and carboxylic acid is 4 to 1. The resin can be cured perfectly at the temperature of 100℃ in 40 min.5 The antifogging performance is assessed by the contract angle and the time of first fogging on the surface of the glass. The mechanical performance is assessed by the adhesion and hardness of the antifogging film.
