Fluorine-silicon acrylic resin nano composite anti-icing coating and preparation method thereof

InactiveCN102321415AReduce the amount of icingAchieve super-hydrophobic anti-icing effectCoatingsHysteresisAcrylic resin
The invention discloses a super hydrophobic anti-icing coating and a preparation method thereof, and is realized by preparing a fluorine contained acrylic resin and combining the fluorine contained acrylic resin with organosilicon resin and nano particles. In a scheme of the invention, the fluorine contained acrylic resin has small surface energy and strong hydrophobicity. The organosilicon resin utilizes effect of -CH3 on a surface thereof and small polarity to substantially reduce contact angle hysteresis. The fluorine contained acrylic resin can crosslink and solidify with the nano particles and active groups in the organosilicon resin to form a composite network. The invention can overcome defects of complex technology, high costs and unsuitability for large scale usage of an ordinary method for preparing a super hydrophobic coating; and the prepared coating can realize super hydrophobic anti-icing effect through a regular spraying method.

Method of preparing molding compositions with fiber reinforcement and products obtained therefrom

A method of preparing fiber reinforced acrylic thickened compositions which can be molded under low pressures and temperatures to provide thermoset articles, wherein liquid reactive components are slowly absorbed in high molecular weight solid acrylic resin in the form of large particles. The acrylic resin functions as a thickener which delays the viscosity build allowing fiber reinforcement to be incorporated before molding. The molding composition is well suited for use in dentistry and other fields where small amounts or molding composition are used occasionally.
