Problems solved by technology

However, the polymerization activity of allyloxy monomers is much lower than that of acrylate monomers, so a large amount of unreacted allyloxy nonylphenoxy propanol polyoxyethylene ether will remain
Although the residual allyloxynonylphenoxypropanol polyoxyethylene ether can also undergo photopolymerization in the coating, its polymerization activity is low, so some parts remain in the coating and do not participate in the curing reaction The formation of a cross-linked network is only physically fixed by the cross-linked network. In the case of high humidity, it is easy to lose and affect the continuous anti-fog performance

Abstract

The invention provides a preparation method of quaternary ammonium salt type hydrophilic ultraviolet curing resin. The preparation method comprises the following steps: performing Michael addition reaction on binary polyether amine and acryloyloyloxyethyl trimethylammonium chloride at room temperature to obtain a double-end secondary amino compound intermediate; and performing Michael addition reaction on the double-end secondary amino compound intermediate and polyfunctionality acrylic ester at 40-45 DEG C to obtain the quaternary ammonium salt type hydrophilic ultraviolet curing resin. The method provided by the invention has the following advantages: (1) the quaternary ammonium salt type hydrophilic ultraviolet curing resin is easily prepared by two-step Michael addition reaction in short time at relatively low temperature; and (2) due to a quaternary ammonium salt structure fixed by a chemical bond on a crosslinking network formed by photo-curing, the quaternary ammonium salt type hydrophilic ultraviolet curing resin can guarantee excellent initial and continuous anti-fog property of a film after being applied to anti-fog coating.

Description

technical field [0001] The invention relates to a preparation method of a quaternary ammonium salt type hydrophilic ultraviolet light curing resin, belonging to the technical field of polymer material synthesis. Background technique [0002] When the water vapor in the air is lower than the dew point, it will condense into tiny liquid droplets to form fog. This adverse effect often occurs in windows, bathroom mirrors, glasses, swimming and diving glasses, windshields, optical instrument lenses, solar cell light-transmitting panels, car lights, indicator lights, agricultural films, etc., which are closely related to our lives. on transparent materials. As a result of the atomization of water droplets on the surface of transparent materials, not only the decrease of light transmittance will affect the vision, but sometimes it will cause harm. For example, when the droplets condense on the lens surface of precision analysis instruments such as infrared optical microscopes, the...
