Abstract

The invention provides a reaction system used for continuously and fast preparing anti-dazzle liquid. The reaction system comprises a storage tank, an impinging stream static mixer, a microwave reactor, a Venturi static mixer, a cooler and a constant flow pump. By adopting a reaction method for preparing the anti-dazzle liquid through the reaction system, silicate ester, alcohol, water and catalyst acid are fast and evenly mixed through the impinging stream static mixer, the mixed materials are fast heated through the microwave reactor so that the temperature can rise, the hydrolysis reaction is further accelerated, and a great deal of silanol obtained through hydrolysis is condensed into a small-sized polycondensation body; the mixed materials are fast mixed with a hindering agent when flowing through the Venturi static mixer, and the hindering agent hinders further condensation reaction of the silanol and growth of the polycondensation body; fast cooling is carried out through the cooler, and the reaction speed is lowered further to obtain the high-stability anti-dazzle liquid. The scheme is simple in technology and high in controllability, the product is stable in performance, easy to produce in quantity, and low in energy consumption, and the reaction system and method have powerful industrializing conditions and prospects.
